Both are invoked from `pkg/frost/signing/native_adapter_registration.go`'s package `init()`, so a transient registration glitch — for example, the `frost_native`/`frost_tbtc_signer` build flavor's FFI lookup returning an error — would crash the binary at startup. Downstream code in `pkg/frost/signing/backend.go` already handles the absence of a registered native adapter through `ErrNativeCryptographyUnavailable`, so the legacy execution backend remains the safe-by-default path when native execution is unavailable; panicking at init turned a recoverable degradation into an outage. Replace the panics with structured `logger.Warnf` calls plus a package-level `lastRegistrationError` and `LastNativeRegistrationError()` accessor. Callers that want to fail startup on a registration error can opt in by checking that accessor after invoking `RegisterNativeExecutionAdapterForBuild`; default callers continue booting with the legacy backend, exactly as if `frost_native` was never enabled. The existing `TestRegisterNativeExecutionFFISigningPrimitiveForBuild_ProviderErrorPanics` becomes `..._ProviderErrorIsRecordedNotPanicked` and asserts the new behavior: no panic, error visible through `LastNativeRegistrationError()`, FFI executor remains unregistered. 2. `parseBuildTaggedTBTCSignerResult` unconditionally deferred `C.tbtc_signer_free_buffer(result.buffer.ptr, result.buffer.len)` even when the C wrapper's status-code -1 path returned `result.buffer.ptr == NULL`. The C wrapper checks the `frost_tbtc_free_buffer` symbol for NULL but does not check the buffer pointer, so a future Rust-side change that dereferenced its ptr argument without a NULL guard would crash. Skip the defer when the buffer pointer is nil. 3. `unmarshalSignerMaterialFromPersistence` accepted any uvarint length within the data buffer. A corrupted state file or a hostile peer carrying a multi-hundred-MiB envelope would allocate that many bytes before the existing bounds check ran. Cap the format length at 256 bytes and the payload length at 256 KiB — comfortably above any real signer material envelope — and reject earlier with a clear error. Add the matching negative tests `TestUnmarshalSignerMaterialFromPersistence_RejectsOversizedFormatLength` and `TestUnmarshalSignerMaterialFromPersistence_RejectsOversizedPayloadLength`.

H1+H4 — scaffold key-group must be opt-in (was silently accepted) `pkg/tbtc/signer_material_resolver_build_frost_native_tbtc_signer.go` previously built signer material whose `KeyGroupSource` was the string `"legacy-wallet-pubkey"` — a placeholder derived from a sha256 of the legacy wallet public key rather than the output of a real FROST DKG run — and the FFI primitive at `pkg/frost/signing/native_ffi_primitive_transitional_frost_native.go` silently substituted the Rust signer's RunDKG key group when the payload's source was that placeholder. Together that meant a production deployment with placeholder material would have routed signing through whatever key group the Rust side happened to return without any operator-facing signal. Add an explicit, refuse-by-default opt-in: `KEEP_CORE_FROST_TBTC_SIGNER_ACCEPT_SCAFFOLD_KEY_GROUP=1`. The new `signing.AcceptScaffoldKeyGroupEnabled` helper is per-call (not cached), so flipping the env back to unset recovers fail-closed behavior without a restart. Both the resolver and the FFI primitive check the flag; both refuse with a clear error message that names the env var and the placeholder source. Existing scaffold-using tests (`TestBuildTaggedTBTCSignerRoundKeyGroup`, `..._LegacyKeyGroupSourceUsesRunDKGResult`, `TestRegisterSignerMaterialResolverForBuild_UsesDefaultProvider`, the `signingExecutor` suite in `pkg/tbtc`) opt in via `t.Setenv` to continue exercising the scaffold path; a new `TestRegisterSignerMaterialResolverForBuild_DefaultProviderRefusesScaffoldWithoutOptIn` pins the refuse-by-default behavior, and a new `TestBuildTaggedTBTCSignerRoundKeyGroup/legacy_source_mismatch_refused_without_opt_in` covers the FFI side. 2. M2+M3 — Bitcoin witness restoration refuses unsupported shapes `pkg/bitcoin/transaction_builder.go`'s `ReplaceUnsignedTransaction` restoration path handled only `len(previousInput.Witness) == 1` (the P2WSH-style single redeem script). Multi-element previous witnesses — what a P2TR script-path spend would carry — were silently dropped, leaving the replaced input with an empty witness that signing later couldn't recover. Out-of-scope for the current P2TR key-path FROST migration but a footgun the next person to touch this code would hit. Switch to an explicit `switch` over previous witness length: 0 leaves the replacement empty, 1 restores the redeem script as before, anything else fails loudly with a clear "only zero- or single-element pre-signing witnesses are currently supported" error. Lifting this to support multi-element witnesses needs a per-input policy (the replacement could legitimately differ in witness shape from the previous), so failing loudly is the safer shape today. Also remove the tautological inner `len(replacedInput.X) == 0` checks that the two outer refusals already guarantee. New regression test `TestTransactionBuilder_ReplaceUnsignedTransaction_RejectsMultiElementPreviousWitness`. 3. M5 — first-write-wins on peer messages The three round-message receive loops (`native_ffi_primitive_transitional_frost_native.go` tbtc-signer contribution, `native_frost_protocol_frost_native.go` round one and round two) all did `receivedMessages[message.SenderID()] = message`, last-write-wins. That let a peer mutate its own contribution after the first send. ROAST evidence semantics call for first-write-wins, with bit-identical retransmissions being idempotent and conflicting retransmissions being dropped with a structured log entry. Each receive loop now checks `receivedMessages[senderID]` first. If present and the new message is byte-equal on the relevant payload fields (`Contribution{Identifier,Data}` for tbtc-signer, `Commitment{Identifier,Data}` for round one, `SignatureShare{Identifier,Data}` for round two), the duplicate is ignored; if different, the new message is dropped with a `protocolLogger.Warnf` line that names the sender. Three equality helpers (`buildTaggedTBTCSignerRoundContributionMessagesEqual`, `nativeFROSTRoundOneCommitmentMessagesEqual`, `nativeFROSTRoundTwoSignatureShareMessagesEqual`) plus a new package-level `protocolLogger` log channel. Verification (local, GOCACHE under /private/tmp): go test ./pkg/frost/... ./pkg/bitcoin go test -tags 'frost_native frost_tbtc_signer' ./pkg/frost/... ./pkg/bitcoin go test -tags 'frost_native frost_tbtc_signer' ./pkg/tbtc -run \ 'TestConfigureFrostSigningBackend|TestNewNode_ConfiguresFrostSigningBackend|TestSigningExecutor_Sign|TestRegisterSignerMaterialResolverForBuild|TestBuildTaggedTBTCSignerRoundKeyGroup|TestBuildTaggedLegacyCompatibleNativeExecutionFFISigningPrimitive|TestTransactionBuilder_ReplaceUnsignedTransaction' All pass. This is the safe-by-default tier of the PR #3866 review remediation; the M4 (ROAST bounded transition evidence) and M7 (ROAST-aware retry replacing the byte-identical tECDSA shuffle) tracks are separate multi-PR efforts, and L5 (FFI status-code semantics) is paired with a forthcoming tbtc-signer change.

What neither fix covered: scaffold material persisted from a previous opted-in session can still drive the FFI signing path on later runs after the operator has unset the flag. The signing path feeds `buildTaggedTBTCSignerDKGPlaceholderPublicKeyHex(identifier)` — a non-curve-point 3-byte string like `"020001"` — into the Rust signer's `RunDKG` for every included participant. The bootstrap signer is permissive about this shape; a future production signer would not be, and the per-cycle leak of placeholder identifiers into telemetry and blame attribution is its own concern. Close the persistence-vs-execution gap by refusing to enter the FFI signing path at all when the payload is scaffold-era and the operator has not actively opted in for this process. The check sits at the top of `signWithTBTCSignerCoarseEngine` immediately after the signer material is decoded — before the engine availability check, before member-set determination, before `buildTaggedTBTCSignerRunDKGInputsForIncludedMembers` runs — so placeholder participant pubkeys are never built when the flag is unset. The fence is per-call (not cached), matching the contract on `AcceptScaffoldKeyGroupEnabled`: flipping the env back unset recovers fail-closed behavior without a restart. The error wraps `ErrNativeCryptographyUnavailable` so any caller that already handles the "native cryptography is unavailable" condition treats this the same way; downstream callers that want to surface a more specific "scaffold refused" diagnostic can match on `AcceptScaffoldKeyGroupEnvVar` in the error message. New regression test pins the fence behavior: `..._Sign_TBTCSignerPath_RefusesScaffoldMaterialWithoutOptIn` registers a working mock engine, omits the env var, calls `Sign`, and asserts the refusal references both the env var and the placeholder source, plus that `RunDKG`, `StartSignRound`, and `FinalizeSignRound` were all not called. The existing scaffold-path tests (`..._BootstrapVersion_LegacyKeyGroupSourceUsesRunDKGResult`, `..._BootstrapVersion_InvalidCoarseSignatureFallsBack`, `..._NoEngineNoLegacyShare`, `..._AttemptVariationRunDKGConflictFallsBack`, `..._BootstrapVersion_AttemptVariationStartSignRoundConflictFallsBack`, `..._InvalidAttemptPolicy_DoesNotFallback`, `..._ConsumedAttemptReplay_DoesNotFallback`) opt in via `t.Setenv` so they continue to exercise the scaffold path beyond the fence. Verification (local, GOCACHE under /private/tmp): go test -tags 'frost_native frost_tbtc_signer' ./pkg/frost/... go test -tags 'frost_native frost_tbtc_signer' ./pkg/tbtc -run \ 'TestConfigureFrostSigningBackend|TestNewNode_ConfiguresFrostSigningBackend|TestSigningExecutor_Sign|TestRegisterSignerMaterialResolverForBuild' All pass.

This consumer change makes `isBuildTaggedTBTCSignerConsumedAttemptReplayError` prefer that code when it is reachable through the error chain so any future cosmetic rewording of the Rust message on either side cannot silently break replay detection. The structured form is plumbed through by introducing a new `buildTaggedTBTCSignerStructuredError` type that carries `Code` and `Message` from the FFI envelope. `buildTaggedTBTCSignerResultStatusError` wraps that struct via `%w` so callers can extract it through `errors.As`. The existing `buildTaggedTBTCSignerErrorMessage` is refactored to `buildTaggedTBTCSignerErrorPayload` returning the struct directly; the rendered error-chain string still has the form `"code: message"` so log readers see no change. The detector then implements a small policy ladder: 1. If a structured envelope carries the new `consumed_attempt_replay` code, return true. 2. If a structured envelope carries the legacy `validation_error` code (pre-dedicated-variant signers route the replay path through `EngineError::Validation`), substring-match only the Message field so unrelated `validation_error`s carrying noise in their wrapping chain are not mistaken for replays. 3. Any other recognized code is authoritative and not a replay. 4. If no structured envelope is reachable at all (pre-envelope signer builds), fall back to substring-matching the whole rendered string. The legacy wording is preserved by the current tbtc-signer release so this branch continues to work during the rolling upgrade window. Two new test functions cover the new behavior: - `TestIsBuildTaggedTBTCSignerConsumedAttemptReplayError` runs eight cases through the detector: nil, structured code matches, structured but different code rejects, structured empty code with legacy wording in the message accepts, plain-wrapper string accepts, legacy `validation_error` with replay wording accepts, `validation_error` with unrelated message rejects, unrelated error rejects. - `TestBuildTaggedTBTCSignerErrorPayload` exercises the new decoder against structured envelopes, message-only envelopes, completely empty envelopes, and malformed payloads. Verification (local, GOCACHE under /private/tmp): go test -tags 'frost_native frost_tbtc_signer' ./pkg/frost/... ./pkg/bitcoin go test -tags 'frost_native frost_tbtc_signer' ./pkg/tbtc -run \ 'TestConfigureFrostSigningBackend|TestNewNode_ConfiguresFrostSigningBackend|TestSigningExecutor_Sign|TestRegisterSignerMaterialResolverForBuild' All pass. This is the keep-core side of L5 from the independent PR #3866 review. The Rust side is the matching tlabs-xyz/tbtc PR that introduces the `consumed_attempt_replay` code.

Today the package layout names ROAST +concepts (`pkg/frost/roast`, `pkg/frost/retry`) but the actual semantics fall +short of the protocol in two specific places: + +* The retry policy in `pkg/frost/retry/retry.go` is byte-identical to the + tECDSA shuffle in `pkg/tecdsa/retry/retry.go`. It is a deterministic + participant shuffle, not ROAST-aware attempt advancement. +* The three FFI/native-FROST receive loops in `pkg/frost/signing/` drop + channel overflows with `select { default }`, with no bounded transition + evidence and no retransmission contract. + +This RFC proposes a layered design that closes both gaps together, because +they share the same notion of *attempt context* and *transition evidence*. +It is broken into discrete PR-sized phases so the migration can land +incrementally without regressing the existing signing flow. + +== Motivation + +The ROAST paper (Ruffing-Ronge-Aranha-Schneider, CCS 2022) describes a +coordinator-driven retry protocol that turns FROST's brittle round +synchronisation into an asynchronous robust signing primitive. The key +invariants are: + +1. *Attempt context.* Every signing attempt is bound to a deterministic + context (session, key group, message digest, attempt counter, included + participant set). All in-flight protocol messages must reference the + attempt context they belong to. Messages for a stale or future attempt + must not influence the current attempt's transcript. +2. *Transition evidence.* When the coordinator moves an attempt forward it + must publish (or be able to publish on demand) evidence that justifies + the transition: which contributions arrived, which were rejected, which + peers failed to respond within the attempt's bound, and what new + exclusion set the next attempt should use. This is what makes the + protocol *robust* rather than relying on optimistic liveness. +3. *Deterministic exclusion.* The next attempt's participant set is a pure + function of the previous attempt's transition evidence (plus the + original group + seed). Two honest coordinators driving the same session + must arrive at the same attempt context. + +The byte-identical `EvaluateRetryParticipantsForSigning` shuffle satisfies +none of these. It re-shuffles the same set deterministically using +`(seed, retryCount)`. It has no notion of which participants were +*blamable* in the previous attempt, no exclusion ledger, and no message +context binding. + +The receive-loop drop is more subtle but equally protocol-violating: a +silent drop on channel overflow means that two participants observing the +same network can end up with divergent transcripts -- one with the +contribution, one without -- and there is no evidence trail to detect or +recover from that divergence. The `select { default }` pattern is fine for +optimistic transport but not as the canonical mechanism for protocol +membership. + +The two findings cluster naturally: + +* M4 (the receive drop) is the source of evidence. +* M7 (the retry shuffle) is the consumer of evidence. + +A change that fixes M7 without M4 has nothing to drive retry decisions on. +A change that fixes M4 without M7 produces evidence that no consumer reads. +This RFC therefore treats them as one design split into phases, not as two +independent fixes. + +== Background: ROAST in brief + +For implementers approaching this RFC fresh, the relevant ROAST surface is: + +* A *session* fixes the key group, the message digest, and the original + signer set. +* Each session goes through one or more *attempts*. An attempt is + identified by `(session_id, attempt_number)` and contains an *included + set* of participants and an *excluded set* of participants known to be + unable or unwilling to complete this attempt. +* The *coordinator* of an attempt is selected deterministically from the + included set (this is already implemented in `pkg/frost/roast/coordinator.go` + via `SelectCoordinator`). +* The coordinator collects round-one commitments, round-two signature + shares, then either: +** Aggregates a signature when t-of-n shares arrive within the attempt's + time bound -- the session is done. +** Times out and emits *transition evidence*: the set of peers that did + not contribute on time, and the new excluded set the next attempt + should use. + +The retry shuffle in keep-core's tECDSA path predates ROAST and answers a +different question -- "if signing fails, who do we try next?". It does so +without distinguishing inactive peers from corrupted ones, and it makes no +attempt to construct an evidence trail. That is appropriate for tECDSA +(which has its own malicious-share detection downstream) and inappropriate +for FROST (which expects the coordinator to be the source of truth for +attempt advancement). + +== Current state + +=== Retry layer + +`pkg/frost/retry/retry.go` exports `EvaluateRetryParticipantsForSigning` +and `EvaluateRetryParticipantsForKeyGeneration`. Both are pure shuffles +seeded by `(seed, retryCount)`. The signing variant takes no input from +the previous attempt's transcript. `diff pkg/frost/retry/retry.go +pkg/tecdsa/retry/retry.go` is empty. + +=== Coordinator layer + +`pkg/frost/roast/coordinator.go` exports `SelectCoordinator`. The function +is correct in isolation -- given an included set and an attempt context it +returns a deterministic coordinator -- but there is no consumer of the +selected coordinator's state. Attempt context is reconstructed +implicitly from `(seed, retryCount)` at the retry layer, with no shared +record of which messages arrived in which attempt. + +=== Receive layer + +`pkg/frost/signing/native_ffi_primitive_transitional_frost_native.go` and +`pkg/frost/signing/native_frost_protocol_frost_native.go` together host +three receive loops: + +* `native_ffi_primitive_transitional_frost_native.go:973` -- tbtc-signer + round contribution capture. +* `native_frost_protocol_frost_native.go:568` -- native FROST round-one + commitments. +* `native_frost_protocol_frost_native.go:650` -- native FROST round-two + signature shares. + +All three use the same shape: + +[source,go] +---- +messageChan := make(chan *T, expectedMessagesCount*4+1) +request.Channel.Recv(recvCtx, func(message net.Message) { + // shouldAcceptNativeFROSTMessage(...) filtering ... + select { + case messageChan <- payload: + default: + } +}) +---- + +The channel is generously sized (`expected*4+1`), and the assembly side +applies first-write-wins / equal-or-reject (added in PR #3959).

No protocol behaviour changes. +* Extend protocol message structs with `AttemptContextHash` field, with + the field optional during the migration so existing peers stay + compatible. + +=== Phase 2: Receiver overflow tracking (M4 layer A) + +* Introduce `AttemptEvidenceRecorder` interface and a no-op default. +* Plumb the recorder through the three receive loops. Default no-op + preserves exact current behaviour. +* Add unit tests showing the recorder captures overflow without + changing receive semantics in the noop path. + +=== Phase 3: Coordinator state machine + +* Promote `pkg/frost/roast/coordinator.go` to a state-tracking + coordinator. Existing `SelectCoordinator` becomes an internal helper. +* Cover deterministic next-attempt computation under unit tests with + property tests for the + `(AttemptContext, TransitionEvidence) -> AttemptContext` map. +* No production code path uses the new coordinator yet -- it ships + unused. + +=== Phase 4: Wire receiver to coordinator + +* Connect the evidence recorder to a real coordinator instance behind + a new build tag (`frost_roast_retry`). +* Existing receive loops still use the noop recorder; the new code + path is reachable only when the build tag is set. +* Add a soak-style test that drives the full attempt -> evidence -> + next-attempt loop under fault injection (synthetic overflow, + synthetic reject, synthetic silence). + +=== Phase 5: Retry adapter + +* Add `EvaluateRoastRetryForSigning` and + `roast.SigningRetryAdapter`. +* Migrate one signing call site behind the `frost_roast_retry` build + tag, leaving the other call sites on the legacy shuffle. +* Wire a feature-flagged readiness gate (analogous to the existing + ROAST strict-mode guard) so production builds refuse to enable the + build tag without explicit operator opt-in. + +=== Phase 6: Migrate remaining call sites + +* Move remaining signing call sites onto the adapter. +* Once the legacy `EvaluateRetryParticipantsForSigning` has no + callers, delete it. (Key-generation legacy retry stays.) +* Remove the build tag; the new retry path is unconditional. + +=== Phase 7: Readiness manifest evidence + +* Update the FROST readiness manifest to flip ROAST retry + + transition evidence from `missing-no-go` to `present` once Phase 6 + ships and the integration test suite has been run against a real + testnet. +* As with every readiness gate in this repo, the manifest is updated + only when the supporting evidence is attached. The RFC does not + promise an early flip. + +== Open questions + +. *Cross-process coordinator agreement.* Today each signer runs its own + process; the coordinator state machine is per-process. We assume + that two honest signers, fed the same `TransitionEvidence` from a + shared gossip layer, produce the same `NextAttempt`. The gossip + layer for transition evidence is not yet designed. Options: +.. Piggy-back on existing FROST broadcast channel -- simplest but + couples evidence to protocol round-trips. +.. Dedicated evidence broadcast topic -- cleaner separation, more + wiring. +.. Coordinator-only authoritative -- only the elected coordinator + produces evidence and other signers verify but don't recompute. + Closest to the paper but loses redundancy. ++ +This is the question that most needs design-time review with +threshold-network/keep-core protocol owners before Phase 3 lands. + +. *Persistence across signer restart.* If a signer crashes mid-attempt, + does it lose its evidence? The paper assumes persistent state. For + keep-core we likely accept evidence loss on restart at first (the + attempt times out and a new attempt is started fresh) and revisit + persistence in a follow-up RFC once we have wire-level evidence. +. *FFI surface.* `tbtc-signer` (the Rust engine) does not need to know + about ROAST coordinator state -- it remains a pure signing engine. + But it does need to surface structured errors that the coordinator + can map to exclusion reasons. PR #425 / #3961 (the L5 paired + change) is the template for this style of error-code wiring. Future + exclusion-relevant errors should follow the same dedicated-variant + pattern. +. *Backward-compat horizon.* Once the `AttemptContextHash` field is on + protocol messages, how long do we accept messages from peers that + omit it? Proposal: optional during Phase 1-5, required at Phase 6, + validation-rejection at Phase 7. + +== Out of scope + +* DKG retry. The key-generation legacy retry stays.

Widen field from int64 to [32]byte. * Elevate signed-evidence gossip on a dedicated topic as the recommended path entering Phase 3 (still open until protocol-owner review). Spell out why deterministic NextAttempt without input agreement produces divergent outputs. * Replace single-value ring with per-category quotas (overflow, reject, conflict, silence) so a peer cannot spam one category to mask another. Bound is now O(|IncludedSet| * sum(quotas)). * Define concrete exclusion thresholds as constants up-front (overflowExclusionThreshold = 4, etc.) rather than leaving the policy parameterised; explain why constants avoid runtime desynchronisation. * Sketch SyncState gossip message as the persistence story for Phase 5+ -- gossiped signed attestations are the persistent record, avoiding on-disk state.

Old peers continue to interop. * Receiver-side Unmarshal validates length-when-present (must be exactly AttemptContextHashFieldLength = 32) but does not yet match against the locally-computed context. Higher-level acceptance lands in a later RFC-21 phase behind a build tag. * Shared helpers in attempt_context_binding.go convert between the on-wire []byte form and the canonical [32]byte hash form. Senders use SetAttemptContextHash; receivers use GetAttemptContextHash to get the hash + presence flag. Equal-or-reject is extended to compare AttemptContextHash bytewise, so a peer that retransmits the same contribution but mutates the binding mid-stream triggers the existing first-write-wins reject path (introduced in PR #3959). 17 new tests cover: length validation; array<->slice round-trip without caller aliasing; per-message marshal/unmarshal round-trip with field absent and present; backward compatibility with pre-Phase-1B JSON; wrong-length rejection; equal-or-reject sensitivity to the new field. All pass under `go test -tags 'frost_native frost_tbtc_signer' ./pkg/frost/...` plus the pkg/tbtc regression subset.

Four targeted edits: 1. Cross-process coordinator agreement -- replaces the all-to-all-with-local-union recommendation (which silently assumed synchronous gossip) with coordinator-proposed aggregation on a dedicated topic, signed with the operator key, with receiver-side bundle verification for censorship detection. Documents the rejected alternatives and the liveness/safety properties. 2. AttemptSeed source -- the DkgGroupPublicKey input to the seed derivation comes from the FFI signer material at attempt construction time, not from a wallet registry lookup. Removes hot-path async coupling and respects layering between core signing and application state. 3. SelectCoordinator seed bridging -- BeginAttempt wraps the legacy int64-seeded SelectCoordinator with a sterile, named adapter that folds the new [32]byte AttemptSeed into the legacy parameter shape. Bridge is exhaustively tested so later edits cannot accidentally desynchronise it. 4. Silence-parking transience -- Layer B exclusion policy now states explicitly that silence-based parking is single-attempt only with no escalation, so a peer falsely labelled silent (late delivery, coordinator censorship) is reinstated by the very next attempt. Permanent exclusion only follows from overflow or non-transport reject events, neither of which can fire on a slow-but-honest peer. Also: removes a stale "(see open question 1)" reference in Layer A, and adds compact decision blocks for the remaining Phase-3 questions (signer-material binding, key reuse, JSON format, message-size budget). Open questions reduced to three: persistence across restart (Phase 5+), FFI surface guidance (follows L5 pattern from PR #425 / #3961), and AttemptContextHash backward-compat horizon (Phase 6+). No code changes. Implementation PRs reference these decisions in their descriptions. --- ...dinator-retry-and-transition-evidence.adoc | 218 +++++++++++++++--- 1 file changed, 180 insertions(+), 38 deletions(-) diff --git a/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc b/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc index 9a8ca0d957..20eec16b8f 100644 --- a/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc +++ b/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc @@ -198,6 +198,14 @@ session inputs; it is never chosen, only derived.

No transport, aggregation, or signature handling yet -- those land in PR 3.3 and later. * pkg/frost/roast/transition_message.go - LocalEvidenceSnapshot: per-signer signed evidence carrying SenderID, AttemptContextHash, sorted OverflowEntry slice, and an OperatorSignature placeholder. - TransitionMessage: coordinator-aggregated bundle carrying the attempt context hash, the elected coordinator's member index, a SenderID-ascending Bundle of LocalEvidenceSnapshots, and a CoordinatorSignature placeholder. - OverflowEntry: JSON-friendly canonical key/value pair for one attempt.Evidence.Overflows entry. Sorting by Sender ascending is enforced at construction and validated at Unmarshal. - NewLocalEvidenceSnapshot: converts an attempt.Evidence map into the canonical sorted-slice form ready for signing. - (*LocalEvidenceSnapshot).Evidence(): reverse conversion to the attempt.Evidence map form. - Type() implementations under the frost_signing/roast/ prefix so net.TaggedUnmarshaler routing can dispatch unambiguously. - Marshal/Unmarshal pair via encoding/json, matching the Phase 1B pattern. - Validation in Unmarshal: zero-sender rejection, 32-byte AttemptContextHash enforcement, MaxSnapshotsPerBundle cap (256), MaxOperatorSignatureBytes / MaxCoordinatorSignatureBytes caps (256 each), bundle ordering by sender ascending, and every snapshot's AttemptContextHash matching the bundle hash. Phase 3.2 deliberately treats the OperatorSignature and CoordinatorSignature fields as opaque length-capped byte slices.

634b2ed955ca899e146eb5c082d4f24597afce83 Mon Sep 17 00:00:00 2001 From: maclane Date: Fri, 22 May 2026 19:52:01 -0500 Subject: [PATCH 112/403] feat(frost/roast): RFC-21 Phase 3.3 -- aggregation + bundle verification Extends the Coordinator interface with the three methods that drive the ROAST coordinator-aggregation flow defined in RFC-21's Resolved Decisions section: * RecordEvidence(handle, snapshot) -- accept a peer's signed LocalEvidenceSnapshot. Validates structure, verifies the operator signature via the configured SignatureVerifier, checks the snapshot's AttemptContextHash matches the handle's bound context, and applies first-write-wins / equal-or-reject semantics. The self-submission is tracked separately so VerifyBundle can later detect coordinator censorship. * AggregateBundle(handle) -- called by the elected coordinator's node. Sorts the accumulated snapshots ascending by SenderID, builds the TransitionMessage, signs the canonical bundle bytes with the local Signer, and transitions the attempt state through Aggregating to Transitioned. Returns ErrNotAggregator when the caller's selfMember is not the elected coordinator. * VerifyBundle(handle, msg) -- called by every receiver. Verifies the bundle's coordinator signature against the attempt's elected coordinator, verifies each contained snapshot's operator signature, and -- when the receiver has already submitted its own snapshot -- verifies that snapshot is present and byte-identical in the bundle. Returns ErrCensorshipDetected when an honest receiver's evidence has been dropped or mutated by the coordinator. Supporting surface (pkg/frost/roast/signature.go): * Signer interface (Sign payload -> sig) -- Phase 4 will wire to pkg/net's operator-key signing. * SignatureVerifier interface (Verify payload, sig, member) -- Phase 4 will wire to pkg/net's member-keys table. * NoOpSigner / NoOpSignatureVerifier for tests that don't exercise the crypto pipeline; preserve the Phase-3.1 NewInMemoryCoordinator convenience constructor. * CanonicalSnapshotBytes / CanonicalBundleBytes -- deterministic JSON encodings the signatures cover. The snapshot encoding omits OperatorSignature; the bundle encoding includes every snapshot's OperatorSignature so the coordinator's signature attests to the exact assembled set. * verifySnapshotSignature / verifyBundleSignature / verifyOwnObservationsPresent -- the receiver-side checks, each testable in isolation. Sentinel errors: ErrNotAggregator, ErrAttemptStateInvalid, ErrAttemptContextMismatch, ErrSnapshotConflict, ErrSignatureInvalid, ErrSignatureMissing, ErrCensorshipDetected. Constructor changes: * NewInMemoryCoordinator() preserves the Phase-3.1 signature; it internally calls NewInMemoryCoordinatorWithSigning(0, NoOpSigner, NoOpSignatureVerifier). The selfMember=0 sentinel disables the censorship-detection check (the caller has no submitted snapshot to verify presence of). * NewInMemoryCoordinatorWithSigning(selfMember, signer, verifier) is the production constructor for Phase 4. The Phase 1B-style validate() methods on LocalEvidenceSnapshot and TransitionMessage are promoted to public Validate() so callers that construct messages in memory can validate without a marshal/unmarshal round-trip. Tests (24 new cases across signature_test.go and bundle_aggregation_test.go): Signature pipeline: * NoOpSigner returns empty; NoOpVerifier accepts everything; NoOp pair is concurrency-safe under 32x32 goroutines. * CanonicalSnapshotBytes excludes OperatorSignature. * CanonicalBundleBytes excludes CoordinatorSignature but includes every snapshot's OperatorSignature. * fakeSigner / fakeVerifier deterministic round-trip with SHA256(memberID || payload). * Tampered-payload rejection. * Coordinator-mismatch rejection. * Censorship-detection helper for missing snapshot and mutated signature; skip semantics for selfMember == 0 and no selfSubmission. Aggregation and verification: * RecordEvidence: nil rejection, unknown handle, context hash mismatch, bad signature, valid-and-idempotent re-submission, conflict rejection, self-submission tracking. * AggregateBundle: non-aggregator rejection, signed bundle build (size, ordering, signature, terminal state), deterministic bundle JSON across different record orderings. * VerifyBundle: valid acceptance, censorship detection, coordinator- signature forgery, snapshot-signature forgery, attempt-context mismatch, nil message, unknown attempt, concurrent record-and-aggregate safety.

Parked members are skipped from THIS attempt only; the attempt after that automatically reinstates them. - NewAttemptContext preserves its seven-argument signature (attempt-zero / no-parking shape); the new NewAttemptContextWithParking is the constructor used by NextAttempt. - Hash() includes the parked set (between ExcludedSet and AttemptSeed in the canonical encoding). - Pinned-fixture reference encoder updated to match. * pkg/frost/roast/coordinator_state.go - Coordinator interface gains NextAttempt. Policy (matches RFC-21 Resolved Decision on silence-parking transience): 1. Permanent exclusion (transport-blamable): overflow count summed across the bundle >= OverflowExclusionThreshold. 2. Permanent exclusion (validation-blamable): reject events -- no-op in Phase 3.4 since the reject category does not yet exist on the recorder; hook documented for a later phase. 3. Silence parking: senders in prev IncludedSet not present in bundle, not now permanently excluded -- moved to TransientlyParked for ONE attempt. 4. Reinstatement: prev TransientlyParked members rejoin IncludedSet automatically. 5. Infeasibility: if next IncludedSet < threshold, return ErrAttemptInfeasible. The "strictly transient" parking discipline is the formal mitigation Gemini's review asked for: a peer falsely labelled silent (network blip, coordinator censorship caught at VerifyBundle) is reinstated by the very next attempt without intervention. Tests (15 cases in next_attempt_test.go): * No-evidence baseline: IncludedSet unchanged, attempt number incremented. * Overflow threshold (4 observers x 1 event = 4) triggers permanent exclusion. * Overflow below threshold (1 < 4) does NOT exclude. * Silent member moved to TransientlyParked, not ExcludedSet. * Previously parked member is reinstated to IncludedSet. * Full park/reinstate cycle across two transitions (N -> N+1 -> N+2): the originally-silent member appears in N+1's TransientlyParked and N+2's IncludedSet. * Original signer set size (|Inc| + |Exc| + |Park|) preserved across transitions. * Determinism: identical inputs produce identical AttemptContext hashes. * Infeasibility: threshold of 5 with only 3 included members returns ErrAttemptInfeasible. * threshold=0 disables the infeasibility check (test seam). * Overflow counts summed across observers, not maxed. * Nil bundle rejected. * Unknown handle rejected with ErrUnknownAttempt. * OverflowExclusionThreshold constant matches RFC-21 specification.

The type is exported in every build so callers construct it without conditional compilation. * RegisterRoastRetryCoordinator stores the dependencies; later registrations overwrite earlier ones (intentional -- supports runtime reconfiguration). * RegisteredRoastRetryCoordinator reports current state via a (deps, ok) pair so receivers can decide between the bounded recorder path and the Phase-2 NoOp fallback. * ResetRoastRetryRegistrationForTest clears state between cases. Build separation: * roast_retry_registration_default_build.go (//go:build !frost_roast_retry) is a permanent no-op stub. RegisterRoastRetryCoordinator is a silent no-op; RegisteredRoastRetryCoordinator always returns (zero, false). The default build therefore preserves Phase-2 receive semantics exactly: no coordinator is ever found. * roast_retry_registration_frost_roast_retry.go (//go:build frost_roast_retry) is the real registry, mutex-protected for concurrent register / lookup. Tests: * Default-build (2 cases): registration silently discarded; reset is a no-op; RegisteredRoastRetryCoordinator returns the zero value with ok=false. * Tagged-build (4 cases): round-trip; later-write-wins; reset clears; concurrent register-vs-lookup under race detector.

The lookup falls back to NoOp when the registry is empty (default build or no caller has registered), so Phase-2 receive semantics are preserved exactly in the default deployment. * pkg/frost/signing/roast_retry_recorder.go - roastRetryRecorderForCollect helper. Consults RegisteredRoastRetryCoordinator and returns attempt.NewBoundedRecorder() when a coordinator is registered, attempt.NoOpRecorder() otherwise. Intentionally not build- tagged: the build-tag gating happens at the RegisteredRoastRetryCoordinator layer. * native_frost_protocol_frost_native.go (round-one + round-two collect call sites) and native_ffi_primitive_transitional_frost_native.go (tbtc-signer contribution collect call site) - Replace attempt.NoOpRecorder() with roastRetryRecorderForCollect(). Comment text updated to point forward to PR 4.3 (snapshot submission via RecordEvidence). Tests: * roast_retry_recorder_test.go (default build, 3 cases) - NoOp behaviour when registry empty. - NoOp behaviour after a default-build Register call (which is a silent stub). - Per-call recorder instances do not share state. * roast_retry_recorder_frost_roast_retry_test.go (tagged build, 2 cases) - Bounded recorder accumulates overflows when a coordinator is registered. - Reset reverts to NoOp behaviour. Phase 2's test surface (evidence_overflow_test.go etc.) still uses attempt.NoOpRecorder() / attempt.NewBoundedRecorder() directly, so the helper's contract is exercised independently from the receive loops.

Submission is a deferred call so it runs on both the success and error return paths. The orchestration that populates the session-handle binding (SetCurrentAttemptHandleForSession) is Phase 5 work, so the submission path is dormant in production deployments today: the helper sees no binding and returns silently. The code path is unit-tested via a binding installed by the test itself, so regressions land at code review. Files: * pkg/frost/signing/roast_retry_attempt_handle_default_build.go (//go:build !frost_roast_retry) - SetCurrentAttemptHandleForSession, ClearCurrentAttemptHandleForSession, ResetSessionHandleRegistryForTest, and currentAttemptHandleForCollect are no-op / always-false stubs. * pkg/frost/signing/roast_retry_attempt_handle_frost_roast_retry.go (//go:build frost_roast_retry) - sync.RWMutex-protected map from sessionID to sessionAttemptBinding{handle, context}. - Set / Clear / Reset functions; later-binding-wins by design (a session whose attempt has transitioned re-binds). * pkg/frost/signing/roast_retry_submit.go - submitSnapshotIfActive(sessionID, recorder): no-op unless all of (registry populated, session bound, recorder non-empty); when all three hold, builds a signed LocalEvidenceSnapshot and calls Coordinator.RecordEvidence. Errors logged at WARN, never propagated, so a transient submission failure cannot break the signing flow. - buildSignedSnapshot helper isolates the canonicalisation + signing chain so failures are surfaced precisely in logs. * native_frost_protocol_frost_native.go (round-one + round-two callers) and native_ffi_primitive_transitional_frost_native.go (tbtc-signer contribution caller) - Capture the recorder by name (no longer inline). - defer submitSnapshotIfActive(request.SessionID, recorder) before calling collect, so submission runs on both success and error returns. Tests (7 cases in roast_retry_submit_frost_roast_retry_test.go, plus the default-build path is exercised by existing tests): * submit no-op when registry empty * submit no-op when session unbound * submit no-op when recorder snapshot is empty * submit signed snapshot with the right SenderID, signed payload, and overflow contents when bound + populated * SetCurrentAttemptHandleForSession: later binding overwrites earlier * Clear removes the binding * RecordEvidence error is logged, not propagated; caller does not observe failure All pass under: go test ./pkg/frost/signing/..., go test -tags 'frost_roast_retry' ./pkg/frost/signing/..., go test -race -tags 'frost_native frost_tbtc_signer frost_roast_retry' ./pkg/frost/signing/..., staticcheck -checks '-SA1019' ./pkg/frost/..., gofmt -l ./pkg/frost/signing/, go vet ./pkg/frost/....

The harness bypasses the receive-loop wiring (which is unit-tested in pkg/frost/signing under the frost_roast_retry tag) and drives the Coordinator API directly with synthetic snapshots. The novel property it exercises is multi-instance agreement: every node's NextAttempt result must hash-match every other node's, regardless of which fault-injection scenario was run. Tests (6 scenarios in multi_coordinator_soak_test.go): * Clean attempt -- no overflow, no silence -> IncludedSet unchanged at next attempt; nothing excluded or parked. * Overflow exclusion -- 4 observers report 1 overflow each against member 3 (sum = OverflowExclusionThreshold) -> member 3 permanently excluded next attempt. * Silence parking -- member 3 silent -> member 3 parked at next attempt; not permanently excluded. * Park + reinstate cycle -- N+1 parks member 3 (silent at N); N+2 reinstates member 3 (still silent at N+1 by design, cannot submit while parked). * Infeasibility -- threshold = 5 with two silenced members -> every node's NextAttempt returns ErrAttemptInfeasible. * Original signer set preservation -- |Inc| + |Exc| + |Park| invariant holds across three consecutive transitions. Cross-instance agreement is asserted by every soakAttempt invocation: the helper computes NextAttempt on every node's local Coordinator instance and refuses to return until every result's hash matches every other's. A single divergence anywhere causes the test to fail with a precise hash comparison. soakSigner produces SHA-256(memberID || payload) signatures; the matching soakVerifier accepts byte-identical recomputations. No real crypto needed -- the harness exercises the policy + canonical- encoding contracts, not key infrastructure. Verification: * go test ./pkg/frost/roast/... -- pass * go test -race ./pkg/frost/roast/... -- pass * go test -tags 'frost_native frost_tbtc_signer frost_roast_retry' ./pkg/frost/... -- pass (5 packages) * staticcheck -checks '-SA1019' ./pkg/frost/... -- silent * gofmt -l ./pkg/frost/roast/ -- silent Stacked on Phase 4.3 (#3974).

Phase 5 description -- removed the "migrate one signing call site" step. Phase 5 now ships only the adapter, session orchestration, and readiness gate. A partial migration would fracture the attempt-context binding across rounds within a single session (e.g., round-one on ROAST, round-two on legacy shuffle): the evidence captured in round-one would disconnect from the participant selection in round-two. The readiness gate is the risk-management mechanism, not partial migration. 2. Phase 6 description -- changed "Move remaining signing call sites" to "Migrate all signing call sites in a single coordinated change". The three flows share one attempt context per session; migrating them together preserves the round-to-round binding. 3. New Resolved Decisions subsection -- documents a periodic TTL sweep over sessionAttemptBindings (default two hours) so a goroutine panic before the deferred ClearCurrentAttemptHandleForSession cannot leak bindings indefinitely. The eviction is a defence-in-depth backstop, not a substitute for session-completion correctness. Doc-only; no code changes. The TTL implementation lands in Phase 5.2 alongside the session orchestration it backstops. --- ...dinator-retry-and-transition-evidence.adoc | 81 +++++++++++++++---- 1 file changed, 67 insertions(+), 14 deletions(-) diff --git a/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc b/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc index 20eec16b8f..4a97f849e6 100644 --- a/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc +++ b/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc @@ -413,22 +413,50 @@ choices in their PR descriptions and reviews. next-attempt loop under fault injection (synthetic overflow, synthetic reject, synthetic silence). -=== Phase 5: Retry adapter - -* Add `EvaluateRoastRetryForSigning` and - `roast.SigningRetryAdapter`. -* Migrate one signing call site behind the `frost_roast_retry` build - tag, leaving the other call sites on the legacy shuffle. -* Wire a feature-flagged readiness gate (analogous to the existing - ROAST strict-mode guard) so production builds refuse to enable the - build tag without explicit operator opt-in. - -=== Phase 6: Migrate remaining call sites - -* Move remaining signing call sites onto the adapter. +=== Phase 5: Retry adapter, session orchestration, readiness gate + +* Add `EvaluateRoastRetryForSigning` and `roast.SigningRetryAdapter` + with a `ChainAddressResolver` interface to bridge + `group.MemberIndex` (ROAST namespace) to `chain.Address` (legacy + namespace). +* Wire session orchestration at the layer that constructs + `NativeExecutionFFISigningRequest`: at session start call + `Coordinator.BeginAttempt` and `SetCurrentAttemptHandleForSession`; + on session end call `ClearCurrentAttemptHandleForSession` from a + deferred cleanup so success and failure paths converge. +* Add a TTL eviction sweep over `sessionAttemptBindings` (default + two hours) so a goroutine panic before the deferred clear cannot + leak bindings indefinitely (see Resolved decisions). +* Wire a feature-flagged readiness gate + (`KEEP_CORE_FROST_ROAST_RETRY_ENABLED=true`) so production builds + with the `frost_roast_retry` tag still refuse to wire orchestration + without explicit operator opt-in.

No consumer wired yet; Phase 6 migrates the three production call sites onto the adapter in a single coordinated change. * pkg/frost/roast/signing_retry_adapter.go - MemberToParticipantResolver[T] interface bridges group.MemberIndex (ROAST namespace) to T (legacy namespace -- typically chain.Address in production keep-core flows). The interface is generic in T so pkg/frost/roast does not import any caller-side type. - EvaluateRoastRetryForSigning[T]: pure function. Calls Coordinator.NextAttempt, converts the next IncludedSet via the resolver, returns ([]T, AttemptContext, error). Propagates ErrAttemptInfeasible unchanged so callers cannot accidentally swallow the threshold-floor failure. - SigningRetryAdapter[T] struct: binds the inputs onto a value so call sites can hold the configuration once and call EvaluateRetryParticipantsForSigning (legacy-shaped) per retry. Includes NextAttemptContext() for callers that need the AttemptContext to re-bind session orchestration. Generic-in-T design (Gemini's Phase-5 design review): * Production callers instantiate as SigningRetryAdapter[chain.Address] * Tests use SigningRetryAdapter[string] or [int] for simplicity * pkg/frost/roast stays decoupled from pkg/chain Tests (9 cases in signing_retry_adapter_test.go): * HappyPath: 5-member group, all submit -> 5 addresses returned in IncludedSet order * PropagatesInfeasibility: high threshold -> ErrAttemptInfeasible surfaces unchanged * PropagatesResolverError: resolver failure wraps with member index context, errors.Is sentinel passes * RejectsNilCoordinator * RejectsNilResolver * SigningRetryAdapter_LegacyShapeMatchesPureFunction: legacy-shaped method returns same participants as the pure function * NextAttemptContextRoundTrip: NextAttemptContext is deterministic across repeated calls * PropagatesInfeasibility via the struct method as well All pass under: go test ./pkg/frost/roast/..., go test -race ./pkg/frost/roast/..., go test -tags 'frost_native frost_tbtc_signer frost_roast_retry' ./pkg/frost/..., staticcheck -checks '-SA1019' ./pkg/frost/..., go vet ./pkg/frost/..., gofmt -l ./pkg/frost/roast/.

21:05:11 -0500 Subject: [PATCH 120/403] feat(frost/signing): RFC-21 Phase 5.2 -- orchestration helpers + TTL sweep Adds the session-orchestration entry points Phase 6 will wire from production call sites, plus the background TTL-eviction sweeper documented in RFC-21's Resolved Decisions section. * pkg/frost/signing/roast_retry_orchestration.go (new, untagged) - BeginOrchestrationForSession(sessionID, ctx) -> (handle, cleanup, error) calls Coordinator.BeginAttempt and SetCurrentAttemptHandleForSession; returns a cleanup function the caller defers. - EndOrchestrationForSession(sessionID) is the cleanup convenience when the cleanup function cannot be captured. - In the default build the helper returns an error directing the caller to fall back to legacy behaviour; production code paths cannot accidentally succeed into orchestration when the build tag is off. * pkg/frost/signing/roast_retry_attempt_handle_frost_roast_retry.go (extended) - sessionAttemptBinding gains createdAt time.Time. - SessionHandleBindingTTL constant (2h, matching RFC-21). - SessionHandleSweepInterval constant (15m). - StartSessionHandleSweeper() launches the background goroutine via sync.Once; safe to call multiple times. - sessionHandleSweepLoop ticks at the interval and calls evictStaleSessionHandleBindings. - evictStaleSessionHandleBindings(maxAge) is exposed at package level so tests can call it directly with small TTLs without waiting for the ticker. - ResetSessionHandleRegistryForTest now also stops the sweeper and resets the sync.Once so each test starts fresh. * pkg/frost/signing/roast_retry_attempt_handle_default_build.go (extended) - StartSessionHandleSweeper is a no-op stub. * pkg/frost/signing/roast_retry_registration_frost_roast_retry.go (extended) - RegisterRoastRetryCoordinator calls StartSessionHandleSweeper so the defence-in-depth backstop is active whenever orchestration could plausibly run. Tests: * roast_retry_orchestration_test.go (default build, 1 case) - BeginOrchestrationForSession returns an error when registry empty (which it always is in the default build). * roast_retry_orchestration_frost_roast_retry_test.go (tagged build, 9 cases) - HappyPath: Begin populates binding, cleanup removes it - Error when registry empty - Error when registered Coordinator is nil - Error when BeginAttempt fails (synthetic erroring coordinator) - EndOrchestrationForSession removes the binding - evictStaleSessionHandleBindings evicts old entries via direct timestamp manipulation; survives fresh ones - Sweep with default TTL evicts nothing for fresh bindings - SessionHandleBindingTTL constant matches RFC-21 (2h) - StartSessionHandleSweeper idempotent under repeated calls - RegisterRoastRetryCoordinator starts the sweeper exactly once even under repeated registration (verified by Reset not double-closing the stop channel) All pass under: go test ./pkg/frost/signing/..., go test -tags 'frost_roast_retry' ./pkg/frost/signing/..., go test -race -tags 'frost_native frost_tbtc_signer frost_roast_retry' ./pkg/frost/signing/..., staticcheck -checks '-SA1019' ./pkg/frost/..., gofmt -l ./pkg/frost/signing/, go vet ./pkg/frost/....

The env var is the load-bearing gate; missing opt-in short-circuits orchestration even when the registry has a real coordinator. Tests: * roast_retry_readiness_test.go (7 cases, untagged) - Accepts "true" - Accepts true case-insensitive (true / True / TRUE / tRuE) - Accepts trimmed whitespace - Rejects unset (returns ErrRoastRetryReadinessOptOut; error message names the env var) - Rejects other values (false / 1 / yes / TRUE_ / tru / anything) - RoastRetryReadinessOptInEnabled mirrors the Ensure result - Env var name matches RFC-21 specification (locks the name) * roast_retry_orchestration_frost_roast_retry_test.go (extended) - Existing happy-path / error tests get t.Setenv(envVar, "true") so they reach the path under test. - New: TestBeginOrchestrationForSession_ErrorsWhenReadinessOptInUnset -- asserts a registered coordinator alone is not enough; missing env var still short-circuits orchestration.

Orchestration error taxonomy. The orchestration call from the executor adapter into BeginOrchestrationForSession can fail for two fundamentally different reasons that must NOT be collapsed into a single "fall back to legacy" path: - Static-configuration errors (env var unset, no coordinator registered): fall back to legacy. These errors are deterministic across nodes; every honest signer observes the same outcome from the same configuration. - Runtime state-machine errors (Coordinator.BeginAttempt failure, internal invariant violated, etc.): hard fail. These errors are non-deterministic; a fall-back-on-error policy would let node A run the legacy shuffle while node B proceeds with the ROAST state machine, splitting the signing group on NextAttempt. The decision is load-bearing for Phase 6 safety. Sentinel errors ErrRoastRetryReadinessOptOut and ErrNoRoastRetryCoordinatorRegistered (introduced in Phase 6.3) identify the static class via errors.Is. 2. FrostUniFFIV1 signer-material prerequisite. Phase 6.1's ExtractDkgGroupPublicKeyFromMaterial cannot extract the DKG group public key from V1 material. The Phase 7 readiness manifest flip is therefore gated on verified migration off V1 across production signers. The migration tracking mechanism is out of scope for this RFC; the prerequisite is documented here as a hard dependency. Doc-only; no code changes. Phase 6.3 implements the error taxonomy; the V1 prerequisite is verified before Phase 7 ships. --- ...dinator-retry-and-transition-evidence.adoc | 59 +++++++++++++++++++ 1 file changed, 59 insertions(+) diff --git a/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc b/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc index 4a97f849e6..f1ddcd5a73 100644 --- a/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc +++ b/docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc @@ -634,6 +634,65 @@ field on `sessionAttemptBinding`.

Phase 6.3 calls this from the executor adapter; Phase 6.4 may use it from the migration call sites. * pkg/frost/signing/attempt_context_from_request.go (new, gated frost_native) - BuildAttemptContextFromRequest(*NativeExecutionFFISigningRequest) returns (AttemptContext, error). Strict ordering: signer material is decoded BEFORE the AttemptContext is constructed, so an extraction failure surfaces a clean error rather than a half-built context (mitigation for Gemini's Phase-6 review hidden assumption). - Format-aware KeyGroupID derivation (per RFC-21 Resolved Decision): FrostUniFFIV2: HASH160(0x02 || xOnlyOutputKey) via frost.WalletPublicKeyHashCompatibilityAlias -- matches RFC-20's compatibility-alias scheme exactly. FrostTBTCSignerV1: the raw KeyGroup string from NativeTBTCSignerMaterialPayload -- the tbtc-signer engine treats it as the canonical per-group handle. - AttemptNumber is converted from keep-core's 1-based Attempt.Number to RFC-21's 0-based AttemptContext.AttemptNumber. Rejects Attempt.Number == 0 (must be >= 1). - TransientlyParked is empty: Phase 6 ships attempt-zero shape. Multi-attempt orchestration with parking metadata lands in Phase 7+. - messageDigestFromBigInt helper converts *big.Int message to the 32-byte canonical digest, left-padding short values. Sentinel error: ErrAttemptContextConstruction wraps every construction failure so callers distinguish it from runtime ROAST errors via errors.Is. ErrUnsupportedSignerMaterialFormat from PR 6.1 propagates through wrapped chains intact. Tests (15 cases in attempt_context_from_request_test.go): * UniFFIV2_HappyPath * UniFFIV2_KeyGroupIDDerivation -- verifies HASH160 exactly via the reference function * TBTCSignerV1_KeyGroupIDIsRawIdentifier * RejectsNilRequest -- with sentinel * RejectsNilMessage * RejectsNilSignerMaterial * RejectsNilAttempt * RejectsZeroAttemptNumber * PropagatesExtractionErrors -- ErrUnsupportedSignerMaterialFormat unwraps correctly even after ErrAttemptContextConstruction wraps * AttemptNumberIsZeroBased (3 sub-cases: 1->0, 2->1, 5->4) * DeterministicAcrossInvocations -- two calls with same request produce byte-identical AttemptContext hashes * HashChangesWhenMessageDigestChanges * HashChangesWhenIncludedSetChanges * messageDigestFromBigInt: PadsShortBigInts * messageDigestFromBigInt: RejectsLongBigInts * SmokeTestSha256Length -- AttemptContext.MessageDigestLength matches sha256.Size All pass under: go test -tags 'frost_native frost_tbtc_signer' ./pkg/frost/signing/..., go test -tags 'frost_native frost_tbtc_signer frost_roast_retry' -race ./pkg/frost/..., staticcheck -checks '-SA1019' ./pkg/frost/..., go vet ./pkg/frost/..., gofmt -l ./pkg/frost/signing/.

Per the RFC-21 Phase-6 Resolved Decision on orchestration error taxonomy (#3980): - BuildAttemptContextFromRequest failures are treated as STATIC fallbacks. They are per-input deterministic: the same NativeExecutionFFISigningRequest produces the same construction outcome on every honest node. Log at INFO and continue without orchestration. - BeginOrchestrationForSession failures matching ErrRoastRetryReadinessOptOut or ErrNoRoastRetryCoordinatorRegistered are STATIC fallbacks for the same reason (deterministic per deployment configuration). - Any other BeginOrchestrationForSession failure is a RUNTIME Coordinator state-machine error. HARD FAIL: return error from the executor adapter. The signing group must NOT have node A on legacy shuffle while node B is on ROAST state machine, which would fracture NextAttempt agreement. New files: * pkg/frost/signing/roast_retry_executor_entry_default_build.go (//go:build !frost_native) - attemptRoastRetryOrchestrationFromRequest permanent stub returning (nil, nil). The executor adapter compiles and runs in the default build with zero orchestration overhead. * pkg/frost/signing/roast_retry_executor_entry_frost_native.go (//go:build frost_native) - Real implementation. Walks the (build context, begin, return cleanup) sequence with the error-classification discipline. - Defensive nil-logger handling so the existing executor- adapter tests (which pass nil) do not panic. * pkg/frost/signing/roast_retry_orchestration.go (extended) - ErrNoRoastRetryCoordinatorRegistered sentinel. - BeginOrchestrationForSession wraps the sentinel via fmt.Errorf %w so callers can errors.Is it. * pkg/frost/signing/native_ffi_executor_adapter.go (modified) - Execute now calls attemptRoastRetryOrchestrationFromRequest after building the FFI request, defers the cleanup if orchestration started, then proceeds to primitive.Sign as before. Tests: * roast_retry_executor_entry_test.go (default-build, 1 case) - Stub returns (nil, nil) for any input. * roast_retry_executor_entry_frost_native_test.go (frost_native, 4 cases) - Static fallback when no coordinator registered (default-build stub of RegisteredRoastRetryCoordinator returns false). - Static fallback for FrostUniFFIV1 (unsupported format). - Static fallback for nil signer material (deterministic precondition). - Static fallback for zero attempt number. * roast_retry_executor_entry_frost_roast_retry_test.go (frost_native && frost_roast_retry, 4 cases) - Static fallback when readiness env var unset. - Static fallback when registry empty. - Happy path activates orchestration; binding exists; cleanup clears it. - HARD FAIL on synthetic runtime BeginAttempt error. All pass under: go test ./pkg/frost/..., go test -tags 'frost_native frost_tbtc_signer frost_roast_retry' ./pkg/frost/..., go test -race -tags 'frost_native frost_tbtc_signer frost_roast_retry' ./pkg/frost/..., staticcheck -checks '-SA1019' ./pkg/frost/..., gofmt -l ./pkg/frost/signing/, go vet ./pkg/frost/.... Stacked on Phase 6.2 (#3982).

PR 6.4 installs the legacy implementation as the default; Phase 7 will install the ROAST-driven implementation alongside AggregateBundle production at the executor-adapter layer. The migration here is the *abstraction*, not a behavioural change. Both default and frost_roast_retry builds today execute the same legacy retry shuffle. The dispatcher exists so Phase 7 can replace it without touching signing_loop.go's call shape. * pkg/tbtc/signing_loop_roast_dispatcher.go (new, untagged) - signingParticipantSelector interface: single Select method matching the legacy shape, plus a sessionID parameter that Phase 7's ROAST-driven implementation will use to look up the most recent TransitionMessage. - defaultSigningParticipantSelector() returns the legacy impl. * pkg/tbtc/signing_loop_legacy_selector.go (new, untagged) - legacySigningParticipantSelector: calls pkg/frost/retry.EvaluateRetryParticipantsForSigning verbatim. - Documented as the rollback path preserved through Phase 6 so the readiness env var can disable ROAST retry without deleting the legacy code (per the RFC-21 Phase-6 Resolved Decision on rollback preservation). * pkg/tbtc/signing_loop.go (modified) - signingRetryLoop gains participantSelector field; default initialised in newSigningRetryLoop. - qualifiedOperatorsSet now calls srl.participantSelector.Select instead of retry.EvaluateRetryParticipantsForSigning directly. - pkg/frost/retry import removed (only the dispatcher's legacy implementation uses it now). Tests (5 cases in signing_loop_roast_dispatcher_test.go): * defaultSigningParticipantSelector returns the legacy impl * legacy selector delegates to retry.EvaluateRetryParticipantsForSigning * legacy selector propagates retry-shuffle errors * signingRetryLoop routes through the dispatcher (recording selector verifies Select called exactly once and result is surfaced) * selector errors propagate through signingRetryLoop What Phase 7 will add: - AggregateBundle production at the executor-adapter end (the elected coordinator's node generates a TransitionMessage at attempt completion). - Per-session bundle registry so signing_loop can look up the most recent bundle for the message. - ROAST-driven signingParticipantSelector that consumes the bundle via EvaluateRoastRetryForSigning and falls back to the legacy selector when no bundle is available. - Readiness manifest flip once integration tests pass on a real testnet. Verification: * go build ./... -- clean * go test ./pkg/tbtc/... -count=1 -- pass * go test ./pkg/frost/... -count=1 -- pass * staticcheck -checks '-SA1019' ./pkg/... -- silent * go vet ./pkg/... -- clean * gofmt -l ./pkg/... -- silent Pre-existing test failure note: TestNode_RunCoordinationLayer fails under the 'frost_native frost_tbtc_signer frost_roast_retry' tag combination on the integration tip *without* the Phase 6.4 changes (verified by checking out integration-tip's tbtc package and re-running). Not introduced by this PR; tracked separately. Stacked on Phase 6.3 (#3983).

The default-build signing-loop selector therefore always sees "no bundle" and falls back to the legacy retry shuffle. * pkg/frost/signing/roast_retry_bundle_registry_frost_roast_retry.go (//go:build frost_roast_retry) - Real implementation: sync.RWMutex-protected map; TTL matches SessionHandleBindingTTL (two hours). - sessionBundleEntry pairs bundle with createdAt for eviction. - evictStaleTransitionBundles helper for tests + Phase-7+ sweeper integration. - Later Record-calls overwrite earlier ones (latest transition wins). - nil bundles silently discarded. * pkg/frost/signing/roast_retry_orchestration.go (extended) - maybeProduceTransitionBundle helper called from the cleanup function returned by BeginOrchestrationForSession. The helper: 1. Verifies the local node is the elected coordinator for the attempt (skip if not). 2. Checks the attempt is still Collecting (skip if already transitioned -- e.g. signature succeeded, no bundle needed). 3. Calls Coordinator.AggregateBundle. 4. Stashes the result via RecordTransitionBundleForSession (a no-op in default build). - Failures along the path are silent: cleanup must never panic and must never propagate errors into the signing flow's defer chain. A missing bundle just means the next attempt's selector falls back to legacy. Tests: * roast_retry_bundle_registry_test.go (//go:build !frost_roast_retry, 1 case) - Default-build stub is observably no-op. * roast_retry_bundle_registry_frost_roast_retry_test.go (//go:build frost_roast_retry, 5 cases) - Round-trip Record -> TransitionBundleForSession. - Later Record overwrites earlier (latest-wins). - Clear removes the bundle. - Nil bundles silently discarded. - evictStaleTransitionBundles removes old entries while preserving fresh ones. - TTL matches session-handle TTL (bundles must not outlive sessions). * roast_retry_orchestration_bundle_test.go (//go:build frost_roast_retry, 3 cases) - Cleanup on elected coordinator records a non-nil bundle with the correct coordinator id after seeding evidence. - Cleanup on a non-elected coordinator does NOT record a bundle. - Double-cleanup is safe (second call sees Transitioned state and bails silently without panic).

Falls back to the legacy retry shuffle whenever a precondition is missing (no bundle, no registry, no session-handle binding). * pkg/tbtc/signing_loop_selector_default_build.go (//go:build !frost_roast_retry) - defaultSigningParticipantSelector returns legacySigningParticipantSelector. Default-build binary contains no ROAST-retry code paths at all. * pkg/tbtc/signing_loop_selector_frost_roast_retry.go (//go:build frost_roast_retry) - roastSigningParticipantSelector implements the dispatch: bundle absent? -> legacy fallback registry empty? -> legacy fallback no session-handle binding? -> legacy fallback all preconditions met? -> EvaluateRoastRetryForSigning - Errors from EvaluateRoastRetryForSigning (ErrAttemptInfeasible, resolver failure) are propagated unchanged per the RFC-21 Phase-6 hard-fail error taxonomy. Falling back on these runtime errors would let one node use legacy retry while another uses ROAST -- the signing group would fracture on NextAttempt agreement. - membersResolver closure maps group.MemberIndex (1-based) to chain.Address via the supplied members slice. Validates zero and out-of-range inputs. - defaultSigningParticipantSelector returns the ROAST selector; its first action is to check for bundle availability and delegate to the legacy selector when absent. * pkg/frost/signing/roast_retry_attempt_handle_*.go (extended) - Public CurrentAttemptHandleForSession wrapper around the unexported currentAttemptHandleForCollect so the ROAST selector in pkg/tbtc can read the handle. Default-build stub returns ok=false; tagged build returns the real binding. Tests (8 cases across two build configurations): * pkg/tbtc/signing_loop_selector_default_build_test.go (//go:build !frost_roast_retry, 1 case) - Default-build defaultSigningParticipantSelector returns legacySigningParticipantSelector. * pkg/tbtc/signing_loop_selector_frost_roast_retry_test.go (//go:build frost_roast_retry, 7 cases) - Tagged-build default is roastSigningParticipantSelector. - Bundle absent -> legacy fallback succeeds. - Registry empty (bundle recorded but no coordinator registered) -> legacy fallback. - No session-handle binding -> legacy fallback. - membersResolver maps index -> address correctly. - membersResolver rejects zero index. - membersResolver rejects out-of-range index. - End-to-end happy path: register coordinator, bind session, seed snapshots, aggregate bundle, record bundle, Select returns a non-empty address slice via the ROAST path. All pass under: go test ./pkg/tbtc/..., go test ./pkg/frost/..., go test -tags 'frost_roast_retry' ./pkg/tbtc/... ./pkg/frost/signing/..., staticcheck -checks '-SA1019' ./pkg/tbtc/... ./pkg/frost/..., gofmt -l ./pkg/tbtc/ ./pkg/frost/signing/, go vet ./pkg/tbtc/... ./pkg/frost/.... Stacked on Phase 7.1 (#3985). With this PR, the frost_roast_retry-tagged build executes the full ROAST coordinator-driven retry path end-to-end when (a) the operator opt-in env var is set, (b) a coordinator is registered, and (c) a session has progressed past attempt 1 (so a transition bundle exists). Default builds and tagged builds without preconditions met still execute the legacy retry shuffle, so the behavioural rollback path is intact. --- ...oast_retry_attempt_handle_default_build.go | 10 + ..._retry_attempt_handle_frost_roast_retry.go | 9 + pkg/tbtc/signing_loop_roast_dispatcher.go | 16 +- .../signing_loop_roast_dispatcher_test.go | 15 +- .../signing_loop_selector_default_build.go | 12 + ...igning_loop_selector_default_build_test.go | 15 ++ ...signing_loop_selector_frost_roast_retry.go | 127 ++++++++++ ...ng_loop_selector_frost_roast_retry_test.go | 219 ++++++++++++++++++ 8 files changed, 406 insertions(+), 17 deletions(-) create mode 100644 pkg/tbtc/signing_loop_selector_default_build.go create mode 100644 pkg/tbtc/signing_loop_selector_default_build_test.go create mode 100644 pkg/tbtc/signing_loop_selector_frost_roast_retry.go create mode 100644 pkg/tbtc/signing_loop_selector_frost_roast_retry_test.go diff --git a/pkg/frost/signing/roast_retry_attempt_handle_default_build.go b/pkg/frost/signing/roast_retry_attempt_handle_default_build.go index 43a5538f59..8bc28b14da 100644 --- a/pkg/frost/signing/roast_retry_attempt_handle_default_build.go +++ b/pkg/frost/signing/roast_retry_attempt_handle_default_build.go @@ -38,3 +38,13 @@ func currentAttemptHandleForCollect( ) (roast.AttemptHandle, attempt.AttemptContext, bool) { return roast.AttemptHandle{}, attempt.AttemptContext{}, false } + +// CurrentAttemptHandleForSession is the exported alias for +// callers outside the package (e.g. the ROAST-driven signing +// selector in pkg/tbtc).

Captures the three activation prerequisites (build tag, env var, coordinator registration), the behavioural matrix across configurations, the RFC-21 Phase-6 error-handling discipline (static vs runtime errors), and the recommended rollout sequencing. Cross-references every file the multi-phase RFC-21 implementation touched so operators can trace behaviour back to the responsible package. The readiness manifest itself (the cross-repo evidence ledger that gates production enablement) lives in the tlabs-xyz/tbtc monorepo's docs/operations/ directory, not in keep-core.

It is intended for +node operators and release engineers planning a rollout of the new +retry semantics. + +The feature ships as a build-tagged code path. A production +binary built without the tag contains *no ROAST retry code*; +every signing flow uses the pre-RFC-21 legacy retry shuffle. A +binary built with the tag still executes the legacy path unless +the operator explicitly opts in via an environment variable, and +even then the new path silently falls back to legacy whenever its +preconditions are not met. + +== Activation prerequisites + +All three must be true at the same time for the ROAST retry path +to influence participant selection on a given session attempt: + +. *Build tag set.* The keep-core binary is built with + `-tags frost_roast_retry`. Without the tag, the dispatcher + package does not include the ROAST selector at all. +. *Operator opt-in env var.* The runtime environment defines + `KEEP_CORE_FROST_ROAST_RETRY_ENABLED=true` (case-insensitive, + whitespace-trimmed). The variable is read per call (not + cached), so an operator can flip the switch during a debugging + session without restarting the node. +. *Coordinator registered.* A caller has invoked + `signing.RegisterRoastRetryCoordinator(deps)` at process + startup with the node's operator-key signer, the network's + signature verifier, and the node's member index. + +When any of these is missing, the receive loops, executor +adapter, and signing-loop selector all behave as in the legacy +pre-RFC-21 path. The behavioural rollback is therefore *configuration- +only*: toggle the env var off and the next signing attempt uses +the legacy retry shuffle. + +== Behavioural matrix + +[options="header"] +|=== +| Build tag | Env var | Registry | Bundle present | Behaviour +| not set | _any_ | _any_ | _any_ | Legacy retry shuffle +| set | unset | _any_ | _any_ | Legacy retry shuffle (env-var gate) +| set | true | empty | _any_ | Legacy retry shuffle (no coordinator) +| set | true | populated | absent | Legacy retry shuffle (first attempt / no transition yet) +| set | true | populated | present | ROAST `EvaluateRoastRetryForSigning` +|=== + +The bundle is "present" once the elected coordinator's node has +produced a `TransitionMessage` at the end of a prior attempt +(see Phase 7.1 in RFC-21). Until that happens, the ROAST path is +dormant and the legacy path provides liveness. + +== Error handling discipline + +The orchestration layer distinguishes two error classes: + +* *Static-configuration errors.* Env var unset, no coordinator + registered, signer-material format not extractable. These are + deterministic per deployment configuration: every honest signer + observes the same outcome. Logged at INFO, signing flow + continues with the legacy retry shuffle. + +* *Runtime state-machine errors.* `Coordinator.BeginAttempt` + failures, internal invariant violations, + `ErrAttemptInfeasible` from the policy's threshold floor. These + are non-deterministic across nodes. Treated as *hard failures*: + the session is declared failed and the operator is notified + via the standard signing-failure log path. Falling back to + legacy on these errors would let one node use legacy retry + while another uses ROAST, which would split the signing group + on `NextAttempt` agreement. + +This discipline is the load-bearing safety property of the +RFC-21 design and is enforced in +`pkg/frost/signing/roast_retry_executor_entry_frost_native.go`. + +== Production rollout sequencing + +. *Build the binary with the tag.* Internal builds and CI + pipelines already exercise the tag via + `go test -tags 'frost_roast_retry' ./pkg/frost/... ./pkg/tbtc/...`. + Production binaries adopt the tag once the readiness manifest + in the cross-repo tBTC monorepo's `docs/operations/` directory + flips to `present`. +. *Verify FROST/UniFFI V1 migration.* The DKG-pubkey extraction + helper rejects FrostUniFFIV1 signer material. The Phase 7 + manifest flip is gated on verified migration off V1 across + production signers; until that migration completes, ROAST + retry would silently fall back to legacy on V1-bearing nodes. +. *Stage operator opt-in.* Operators set + `KEEP_CORE_FROST_ROAST_RETRY_ENABLED=true` on a subset of nodes + first. Static-configuration fallback guarantees mixed-state + deployments stay correct: nodes without the env var simply use + legacy. Beware: a node with the env var set but no registered + coordinator (e.g., due to a misconfigured startup script) still + uses legacy, so the safety property holds. +. *Monitor for runtime hard-failures.* The "ROAST orchestration" + log lines under + `keep-frost-roast-orchestration` and + `keep-frost-roast-retry` loggers indicate transitions of the + new state machine. A spike in WARN/ERROR entries from these + loggers is the early signal of trouble. +. *Roll back via env var.* If anything misbehaves, unset + `KEEP_CORE_FROST_ROAST_RETRY_ENABLED` and restart (or wait for + the per-call check to flip the next attempt). The legacy code + paths are retained through Phase 6 and 7 deliberately to make + this rollback bit-for-bit safe. + +== Cross-references + +* RFC-21: `docs/rfc/rfc-21-roast-coordinator-retry-and-transition-evidence.adoc` +* Build-tag scaffolding: `pkg/frost/signing/roast_retry_registration_*.go` +* Orchestration entry point: `pkg/frost/signing/roast_retry_orchestration.go` +* Executor-adapter wiring: `pkg/frost/signing/native_ffi_executor_adapter.go` +* Signing-loop dispatcher: `pkg/tbtc/signing_loop_roast_dispatcher.go` +* ROAST-driven selector: `pkg/tbtc/signing_loop_selector_frost_roast_retry.go` +* Bundle registry: `pkg/frost/signing/roast_retry_bundle_registry_*.go` +* Readiness env var: `pkg/frost/signing/roast_retry_readiness.go` +* Coordinator state machine: `pkg/frost/roast/coordinator_state.go` +* Adapter type: `pkg/frost/roast/signing_retry_adapter.go` From ba612b2987501c3ec1ebc03bc8e9662d116926fc Mon Sep 17 00:00:00 2001 From: maclane Date: Fri, 22 May 2026 22:53:34 -0500 Subject: [PATCH 130/403] feat(frost/roast): close M4 -- reject + conflict evidence categories Closes the M4 gap from the original PR #3866 review by adding the two evidence categories the RFC-21 Phase-2 work left as future work: validation-rejection evidence and first-write-wins-conflict evidence. With this PR, the NextAttempt policy can permanently exclude misbehaving peers on all four ROAST blame channels -- transport-overflow, validation-reject, equivocation-conflict, and silence -- instead of just overflow + silence. Why this matters: a peer that only sends malformed messages (validation rejects, never overflows the channel) was previously indistinguishable from a silent peer. The transient silence- parking policy would bench-and-reinstate them indefinitely, never permanently excluding the malicious behaviour. Same for a peer equivocating mid-attempt: the existing first-write-wins assembly correctly dropped the conflicting retransmission but only logged the event -- the bundle carried no structured evidence the coordinator's policy could act on. * pkg/frost/roast/attempt/evidence_recorder.go - EvidenceRecorder interface gains RecordReject(sender, reason) and RecordConflict(sender). - RejectQuotaDefault = 8, ConflictQuotaDefault = 4 (matches categoryQuota in RFC-21 Layer A). - Evidence struct extended with Rejects (map[MemberIndex][]RejectEntry: per-(sender, reason)) and Conflicts (map[MemberIndex]uint). - boundedRecorder: per-reason quota counter keeps each reason bucket independent so a peer cannot saturate one reason to mask another. Conflicts counter saturates at the conflict quota. - noOpRecorder: every category discards. - NewBoundedRecorderWithQuotas(overflow, reject, conflict) constructor for tests; existing NewBoundedRecorderWithQuota preserved for backward compat (defaults reject + conflict quotas). * pkg/frost/roast/transition_message.go - RejectEntry (Sender + Reason + Count) and ConflictEntry (Sender + Count) wire types added. - LocalEvidenceSnapshot gains Rejects []RejectEntry and Conflicts []ConflictEntry, both omitempty. - NewLocalEvidenceSnapshot canonicalises into sorted slices: rejects ascending by Sender then by Reason; conflicts ascending by Sender. - Evidence() reconstructs the map form for downstream consumption. - Validate() enforces sorted-ascending invariants on both new slices. * pkg/frost/roast/next_attempt.go - RejectExclusionThreshold = 1; ConflictExclusionThreshold = 1 (per RFC-21 Layer B). - computeNextAttempt now consults rejectBlamedSenders and conflictBlamedSenders alongside the existing overflowBlamed set. All three feed into the permanent ExcludedSet. - blamedSenders helper factored to share the threshold-comparison + sort logic across the three category helpers. * pkg/frost/signing/native_frost_protocol_frost_native.go and * pkg/frost/signing/native_ffi_primitive_transitional_frost_native.go - Three reject sites: in each of the three receive loops, the shouldAcceptNativeFROSTMessage failure path now calls evidence.RecordReject(senderID, "validation_gate_rejected") before returning. (Previously the message was just dropped.) - Three conflict sites: the first-write-wins assembly loop's "dropping conflicting" branch now calls evidence.RecordConflict(senderID) immediately before the existing log line. (Previously only the log line.) Tests (15 new cases): * pkg/frost/roast/attempt/evidence_recorder_categories_test.go (7) - RecordReject accumulates by reason - RecordReject per-reason quota saturates - Per-reason quotas independent across reasons - RecordConflict accumulates and saturates - All three categories present in Snapshot after mixed input - NoOp recorder inert across all categories - RFC-quota constants match documented values * pkg/frost/roast/next_attempt_categories_test.go (5) - Single reject crosses threshold -> permanent exclusion - Single conflict crosses threshold -> permanent exclusion - Reject and conflict on different senders -> both excluded - Empty rejects+conflicts -> no exclusion (sanity) - Threshold constants match RFC-21 * Receive-loop wiring is covered by existing send/recv tests combined with the recorder unit tests; no new behaviour test added at the integration level because the NoOp default keeps pre-RFC-21 receive semantics observably unchanged. Verification: * go build ./... + go build -tags 'frost_native frost_tbtc_signer frost_roast_retry' ./... -- both clean * go test ./pkg/frost/... + go test -race ./pkg/frost/roast/... + go test -tags 'frost_native frost_tbtc_signer frost_roast_retry' ./pkg/frost/... -- all pass (5 packages) * staticcheck -checks '-SA1019' ./pkg/frost/... -- silent * go vet ./pkg/frost/... + gofmt -l ./pkg/frost/ -- clean This PR completes M4 from the original PR #3866 review.

Default builds and sessions without a ROAST- attempt binding skip enforcement entirely, so the change is observationally identical to pre-Phase-6 behaviour outside the ROAST path. The Phase 1B AttemptContextHash field was structural-only (present, 32 bytes) until now. Senders could populate it but receivers ignored the value -- meaning a peer could send a message bound to attempt N to a receiver running attempt N+1 of the same session and the receiver would accept it as long as SessionID matched. This PR closes that gap. * pkg/frost/signing/attempt_context_binding_validation_frost_native.go (new, gated frost_native) - attemptContextHashCarrier interface so the helper covers all three FROST/tbtc-signer message types via their existing GetAttemptContextHash methods. - verifyMessageAttemptContextHash: looks up the session's handle binding via currentAttemptHandleForCollect. No binding -> return nil (legacy / default build). Binding present + matching hash -> return nil. Binding present + missing hash -> ErrAttemptContextHashMissing. Binding present + mismatched hash -> ErrAttemptContextHashMismatch. * pkg/frost/signing/native_frost_protocol_frost_native.go and * pkg/frost/signing/native_ffi_primitive_transitional_frost_native.go Three receive callbacks updated. After the existing shouldAcceptNativeFROSTMessage gate, each callback now calls verifyMessageAttemptContextHash. Failure paths call evidence.RecordReject(senderID, "attempt_context_hash_mismatch") so the policy can permanently exclude peers that consistently send stale-attempt messages. Tests: * attempt_context_binding_validation_frost_native_test.go (gated frost_native && frost_roast_retry, 5 cases) - No binding -> any message passes - Binding + matching hash -> passes - Binding + missing hash -> ErrAttemptContextHashMissing - Binding + mismatched hash -> ErrAttemptContextHashMismatch - Integration with a real nativeFROSTRoundOneCommitmentMessage via SetAttemptContextHash; rebinding to a different context produces a mismatch * attempt_context_binding_validation_default_build_test.go (gated frost_native && !frost_roast_retry, 1 case) - In the default build the helper always passes regardless of message contents, matching the rollback promise.

The counters increment whenever a metrics-emitting recorder records an event. In default builds and in unregistered-coordinator states the recorder is NoOp, so the counters stay at zero. Operators only see non-zero values once the ROAST-retry registry is populated and live signing flows record evidence -- the "do I have ROAST retry running?" smoke test. * pkg/frost/signing/roast_retry_metrics.go (new, untagged) - Cumulative atomic counters: roastRetryOverflowEvents, roastRetryRejectEvents, roastRetryConflictEvents. - RegisterRoastRetryMetrics(*clientinfo.Registry) registers Source functions under the "frost_roast_retry" application prefix, producing metrics named: - frost_roast_retry_overflow_events_total - frost_roast_retry_reject_events_total - frost_roast_retry_conflict_events_total via the existing ObserveApplicationSource mechanism. - metricsEmittingRecorder wraps an attempt.EvidenceRecorder and bumps the matching counter on each Record* call before delegating to the inner recorder. - Nil-safe: a nil inner recorder collapses to NoOp; a nil clientinfo.Registry is a no-op registration. * pkg/frost/signing/roast_retry_recorder.go (modified) - roastRetryRecorderForCollect now wraps the bounded recorder with newMetricsEmittingRecorder when the registry is populated. NoOp path is unchanged (no metrics emission). Tests (6 cases in roast_retry_metrics_test.go): * Counters increment on Record* (with different per-category counts). * Snapshot delegates to the inner recorder. * Nil inner falls back to NoOp without panicking. * Unregistered coordinator -> NoOp recorder -> no counter bumps. * Concurrent counter increments are race-safe. * RegisterRoastRetryMetrics(nil) is a no-op (defensive guard). Operator wiring: The keep-core node's startup sequence should call RegisterRoastRetryMetrics(&clientinfo.Registry) alongside the existing registry observation calls. Documentation will be added in a follow-up to the rollout guide (docs/development/frost-roast-retry-rollout.adoc).

The decision had been distributed across commit messages, the RFC text, and inline comments on individual sentinel definitions. The block centralises it next to the code that enforces it, so future maintainers can find the rationale without having to reconstruct it from spelunking history. Key statements captured: STATIC errors -> safe to fall back to the legacy retry path. Every honest signer observes the same node-local config at startup so fallback decisions are deterministic across the group. Sentinel: ErrNoRoastRetryCoordinatorRegistered, detected via errors.Is in signing_loop_roast_dispatcher.go. RUNTIME errors -> HARD FAIL. Per-attempt protocol state errors can be observed by some participants and not others within the same attempt; falling back to legacy under those conditions creates split-brain (some operators running new code, others running legacy on the same attempt). The orchestration layer returns these as bare errors that the dispatcher treats as terminal. The block also notes the historical redirect: the earlier design had BeginAttempt failures fall back, on the assumption that BeginAttempt was cheap idempotent setup. Review identified BeginAttempt mutates per-attempt state and can fail from races with concurrent receives, which the static-error fallback can't safely handle. Documenting the "why" prevents the regression from being re-introduced by a maintainer who reads only the code. Pure documentation -- no behaviour change, no test changes.

The byte-identical JSON is checked into both repos; each side's test reads its local copy and asserts its own derivation function reproduces the expected output. If frost.WalletPublicKeyHashCompat- ibilityAlias drifts from BitcoinTx.deriveWalletPubKeyHashFromXOnly on the bridge side, at least one repo's test fails. The drift this catches is the silent killer for the bridge-protocol identity contract: if keep-core derives a different 20-byte alias than the bridge for the same input, FROST wallets registered by the DKG coordinator land at addresses the bridge doesn't recognize, or vice versa. The failure mode is invisible until a wallet is actually created in production. Test cases TestFrostWalletPubKeyHashDerivationVectors Asserts frost.WalletPublicKeyHashCompatibilityAlias produces the expected 20-byte alias for every FROST vector (HASH160(0x02 || xOnlyOutputKey)). TestEcdsaCompressedPubKeyHash160Vectors Asserts HASH160 of the compressed pubkey matches the expected value for every ECDSA vector. The bridge performs this derivation implicitly during registerNewWallet (compress then hash160); this test pins the algorithm on the keep-core side using the same vectors the bridge pins on its side. TestDriftCheckMetadata Pins the drift_check.tbtc_path / drift_check.keep_core_path / drift_check.rule fields, so a future cross-repo CI sync check has stable references. TestFixtureFileShouldExistAtMirrorPath Documents the convention that the file lives at the path the fixture self-declares; a nudge for anyone moving the file. Companion PR tlabs-xyz/tbtc#432 lands the same JSON fixture and the bridge-side test against TestBitcoinTx.deriveWalletPubKeyHashFromXOnly. Both PRs ship together; landing only one provides no drift protection. Lineage Surfaced in the cross-PR review re-evaluation, originally flagged as "Cross-repo walletID derivation test fixture -- separate effort." Priority was raised when the Phase B-2 keep-core DKG coordination protocol became part of the active roadmap; that phase produces walletIDs the bridge must accept, and this fixture validates the contract before B-2's implementation goes through end-to-end testing.

Bundle evidence entries are observer-signed claims, not self-incriminating proofs, so the policy now refuses to take permanent action on any accusation that is not group-established: - ExclusionAccuserQuorum(groupSize, threshold) = f+1 distinct accusers, where f = groupSize - threshold is the byzantine tolerance. At f+1 at least one accuser is honest under the protocol's own t-of-n assumption. Real faults reach the quorum naturally because contributions are broadcast and every honest member observes them; fabricated ones cannot. - Accusers are counted distinctly (one per observer per accused per category); claimed count magnitudes are no longer summed into blame. Reject reasons no longer multiply accusers, and categories are tallied independently instead of summing into each other. - Only members of the previous IncludedSet are credible accusers; accusations against members outside the original signer set are ignored. - Established overflow accusations (transport-blamable) now park transiently instead of excluding permanently: transport pressure can never be made self-incriminating, so it may cost an attempt of liveness but not permanence. - Established reject/conflict accusations still exclude permanently. - Sub-quorum claims are ignored entirely so a single byzantine observer cannot even impose parking liveness costs. RFC-21 Layer B is updated to match, including the verifiability roadmap: once the wire format carries self-incriminating proof (the accused's own signed conflicting bytes; a re-checkable invalid contribution), single-proof exclusion becomes sound and the quorum gate can be relaxed per category. New regression coverage: quorum boundary at f vs f+1 for both permanent categories, fabricated-blame grinding across six attempts, count-magnitude fabrication, cross-category non-summing, non-credible accusers, non-original accused, established-overflow park-and- reinstate cycle, and the production-shape quorum pin (100, 51) = 50.

Flagged in #4026; at Phase-7 wiring every Go-derived attempt context would fail Rust-side validation. This PR makes the Go derivation normative and durable: - RFC-21 Annex A (normative) specifies the derivation, the KeyGroupBytes definition for FrostTBTCSignerV1 material, the 0-based/1-based wire mapping (wire = AttemptNumber + 1), wrapping semantics, and the accepted non-goals (unframed concatenation, first-8-bytes fold, grindability bounds) with rationale. - pkg/frost/roast/testdata/coordinator_seed_vectors.json pins ten end-to-end vectors (seed int64 + selected coordinator), covering attempt 0/1/5/3/7, sparse and production-size (n=100) member sets, opaque key-group handles, and negative folded seeds. The file is regenerated from the Go implementation via ROAST_SEED_VECTORS_REGEN=1 (TestRegenerateCoordinatorSeedVectors), so the vectors provably come from the spec'd input matrix. - TestCoordinatorSeedDerivation_ConformanceVectors consumes the file and pins DeriveAttemptSeed -> foldAttemptSeed -> SelectCoordinator end to end, including the wire-mapping invariant and at least one negative-seed pin so an unsigned port cannot pass. The Rust signer adopts the same derivation and a byte-identical vector copy in the paired PR stacked on #4005.

The tbtc-signer FFI `AttemptContext` + carries `wire_attempt_number = AttemptNumber + 1` (1-based, zero + rejected); implementations consuming the wire form MUST subtract + one before the composition below. +* `IncludedSet`: the attempt's included member indices. + +=== Derivation + +---- +AttemptSeed32 = SHA256(KeyGroupBytes || SessionID || MessageDigest) +ShuffleSeed_i64 = int64_from_be_bytes(AttemptSeed32[0..8]) +SourceSeed_i64 = ShuffleSeed_i64 + int64(AttemptNumber) // two's-complement wrap +Coordinator = GoMathRandShuffle(sort_ascending(IncludedSet), SourceSeed_i64)[0] +---- + +`GoMathRandShuffle` is the exact shuffle of Go's legacy `math/rand`: +`rand.New(rand.NewSource(seed)).Shuffle` -- ported bit-exactly to +Rust in `pkg/tbtc/signer/src/go_math_rand.rs` and pinned by the +cross-language vectors of keep-core PRs #4026/#4027. The addition is +two's-complement wrapping on both sides (Go's defined signed +overflow; Rust `wrapping_add`). + +=== Non-goals and accepted properties + +* The concatenation `KeyGroupBytes || SessionID || MessageDigest` is + not length-framed, so input-boundary collisions are theoretically + expressible. This is accepted: the seed feeds a *non-cryptographic* + shuffle whose only job is deterministic agreement on rotation + order among honest members; every input is independently and + unambiguously bound (and framed) in the `AttemptContext` hash that + protocol messages verify. The seed is not a security boundary, and + no exclusion or signing decision may ever be derived from it. +* Only the first 8 bytes of `AttemptSeed32` influence the shuffle; + the remaining 24 bytes are bound via the `AttemptContext` hash + only. +* Grindability: an adversary who can choose `SessionID` or + `MessageDigest` can bias coordinator rotation order. Session and + message identifiers are protocol-fixed inputs (deposit/redemption + driven), not free adversary choices; rotation-order bias degrades + at worst into the serial-attempt latency bound, never into a + safety property. + +=== History + +Before this annex, the two implementations diverged: the Go layer +derived `fold(SHA256(KeyGroup || SessionID || MessageDigest))` with +0-based attempts while the Rust engine used the first 8 bytes of the +raw `MessageDigest` with 1-based wire attempts (the legacy +`signingAttemptSeed` convention of the pre-ROAST signing loop, which +`pkg/tbtc/signing_loop.go` retains until Phase-7 migrates it to this +annex). The divergence was flagged in keep-core PR #4026 and resolved +by adopting the Go derivation as normative. + == References * Ruffing, Ronge, Aranha, Schneider. ``ROAST: Robust Asynchronous diff --git a/pkg/frost/roast/coordinator_seed_vectors_test.go b/pkg/frost/roast/coordinator_seed_vectors_test.go new file mode 100644 index 0000000000..f27e5c7284 --- /dev/null +++ b/pkg/frost/roast/coordinator_seed_vectors_test.go @@ -0,0 +1,344 @@ +package roast + +import ( + "encoding/hex" + "encoding/json" + "fmt" + "os" + "strconv" + "testing" + + "github.com/keep-network/keep-core/pkg/frost/roast/attempt" + "github.com/keep-network/keep-core/pkg/protocol/group" +) + +// coordinatorSeedVectorsPath is the cross-language conformance vector +// file for the normative coordinator-shuffle seed derivation (RFC-21 +// Annex A).

15:29:36 -0400 Subject: [PATCH 191/403] =?UTF-8?q?docs(rfc-21):=20Annex=20B=20=E2=80=94?= =?UTF-8?q?=20serial-attempt=20latency=20budget=20vs=20on-chain=20timeouts?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RFC-21 runs ROAST attempts serially where paper-ROAST runs up to n-t+1 concurrent sessions. Compute what that costs against the bridge's deadlines instead of asserting it is fine: - As deployed (41 blocks/attempt, signingAttemptsLimit=5): <= ~41 minutes before the loop gives up -- ~175x inside the 5-day redemption timeout. - f-byzantine worst case at a hypothetical f+1=50 attempt limit: ~6.8 hours -- still ~17x inside the redemption timeout. - The binding liveness constraint is therefore NOT serial latency but all-honest-subset sampling: per-attempt success is 0.49/0.24/0.11/ 0.025 for f=1/2/3/5, so for f>=3 the 5-attempt loop fails with better-than-even odds long before any timeout is approached. The node.go attempts-limit rationale assumes f<=2; the production backstops beyond that are inactivity claims, redemption-timeout slashing, and wallet retirement. - Codify the structural fix as a Phase-7+ requirement: t-of-included finalize (first t responsive members; groundwork in the signer's true-late-t-of-n doc) at minimum for redemption signings, bounded n-t+1 concurrency as the follow-on, and alerting when observed failure rates imply f>=3 behaviour until then. Stacked on the Annex A PR so the annex numbering lands in order.

The honest +caveat is the next section. + +=== What actually binds: subset sampling, not serial latency + +An attempt requires every included member to contribute (the +transitional finalize rejects partial contribution sets), and each +attempt's included set is drawn from ready members. The per-attempt +success probability against `f` byzantine-but-announcing members is +the probability of drawing an all-honest `t`-subset: + +[cols="1,2,2"] +|=== +| `f` | P(all-honest subset) per attempt | P(success within 5 attempts) + +| 1 | 0.490 | 0.966 +| 2 | 0.238 | 0.743 +| 3 | 0.114 | 0.454 +| 5 | 0.025 | 0.120 +|=== + +(`P = ∏_{i=0}^{f-1} (49-i)/(100-i)` for `n=100, t=51`; the +`signingAttemptsLimit = 5` rationale in `pkg/tbtc/node.go` assumes +`f ≤ 2`.) + +So for `f ≥ 3` the loop fails with better-than-even odds long before +any timeout is approached: **the binding liveness constraint is +sampling probability, not serial latency**. A patient adversary does +not even need coordinators — any included byzantine member can burn an +attempt by going silent after announcing, and silence parking is +strictly transient by design, so re-announcing members re-poison +later subsets. This is the liveness profile inherited from the +tECDSA-era loop; its production backstops are outside the signing +loop: operator-inactivity claims (`pkg/protocol/inactivity`), +redemption-timeout slashing, and wallet closure/moving-funds +retirement. + +=== The structural fix (Phase-7+ requirement, not an optimization) + +True ROAST semantics remove the per-attempt veto entirely: the +coordinator finalizes with the first `t` *responsive* members of the +included set (t-of-included finalize) and runs up to `n-t+1` bounded +concurrent sessions so a stalling coordinator costs nothing but its +own slot. Under those semantics a silent member costs zero attempts +(they are simply not among the first `t` responders), the sampling +table above becomes irrelevant (any `t` honest responders suffice, +which the `t`-of-`n` assumption guarantees exist), and the worst-case +added latency degenerates to the coordinator-rotation bound. The +design groundwork already exists in the signer repo +(`pkg/tbtc/signer/docs/true-late-t-of-n-finalize-considerations.md`). + +Recommendation codified by this annex: + +. Before the ECDSA-retirement phases, adopt t-of-included finalize for + the ROAST signing path (at minimum for redemption signings, which + carry slashing-backed deadlines). +. Treat bounded concurrent attempts (`n-t+1` cap) as the follow-on + once t-of-included finalize lands; with it, the `f·τ` serial bound + in this annex stops being the worst case and becomes the + no-concurrency fallback. +. Until then, the `signingAttemptsLimit = 5` / `f ≤ 2` assumption and + this annex's tables are the documented envelope; alerting should + fire when observed attempt failure rates imply `f ≥ 3` behaviour. + == References * Ruffing, Ronge, Aranha, Schneider. ``ROAST: Robust Asynchronous From f6375bae6fea78211b77cc82ce98a2163de2fee8 Mon Sep 17 00:00:00 2001 From: maclane Date: Thu, 11 Jun 2026 15:40:49 -0400 Subject: [PATCH 192/403] test(frost/roast): cross-language differential corpus for the coordinator shuffle Widens Go<->Rust math/rand parity from a handful of pinned vectors to a generated 600-case differential corpus over SelectCoordinator: - 216 boundary cases: seeds {0, +/-1, i64 MIN/MAX, MIN+3/MAX-3, the #4026 pin seed and its negation} x attempts {0, 1, 7, u32::MAX} (exercising the two's-complement wrapping seed+attempt composition) x six member sets including unsorted and reversed inputs (pinning the internal sort). - 384 generated cases from a fixed-seed generator sweeping set sizes 1..255 (full group.MemberIndex range), full-range int64 seeds, and small/large/extreme attempt numbers. The corpus is regenerated from the deterministic case matrix via ROAST_SHUFFLE_CORPUS_REGEN=1 and mirrored byte-identically to the Rust signer (pkg/tbtc/signer/testdata/), whose go_math_rand port replays the same 600 cases -- any drift in source seeding, Fisher-Yates order, int31n bounds, sign handling, wrapping, or sorting fails the drifting side's own suite.

From 4f7907829ee93cfbcd537ddb5c79efc7b920e3a7 Mon Sep 17 00:00:00 2001 From: maclane Date: Fri, 12 Jun 2026 09:54:17 -0400 Subject: [PATCH 199/403] feat(frost/roast): protobuf signed-body envelopes for transition evidence Post-merge follow-up #4 from the June 2026 review stack: replace json.Marshal as the canonical signed-bytes encoding for evidence snapshots and transition bundles before Phase 7 wiring ossifies the format. Design - sign what you transmit, verify what you received: - new pkg/frost/roast/gen/pb/evidence.proto: a snapshot is SignedLocalEvidenceSnapshot{body, operator_signature} where body is the serialized LocalEvidenceSnapshotBody; a transition message is SignedTransitionMessage{body, coordinator_signature} whose body embeds every member's signed snapshot envelope VERBATIM (repeated bytes signed_snapshots) - producers marshal a body exactly once at signing time and cache it; parsed messages retain the received body/envelope bytes verbatim; verification always runs over exact received bytes and nothing in the evidence chain is ever re-encoded - signature validity never depends on any serializer's canonical form, across protobuf library versions or across languages (the Phase 7 Rust signer verifies and parses these same bytes) - CanonicalSnapshotBytes/CanonicalBundleBytes are replaced by SignableBytes() accessors; the coordinator's first-write-wins conflict comparison now compares exact signed bytes - Marshal of a received message returns the received envelope verbatim, so evidence bytes survive re-broadcast; wire-legal but non-canonical encodings also survive (pinned by test) - RFC-21 "Evidence message format" decision rewritten accordingly, with the rationale for retiring canonical JSON Tests: existing suite migrated off JSON fixtures (encode helpers bypass production signing to exercise structural rejection); new wire_test.go pins byte-preservation through re-broadcast, verbatim snapshot-envelope embedding in bundles, non-canonical-encoding survival, and tampered-body verification failure. go build ./..., go vet, gofmt clean; frost + tbtc package tests green.

The observer call is now wrapped in recover-and-log. - snapshotEnvelopeForEvidence handed the observer the slice returned by Marshal, which is the snapshot's internal wire-envelope cache (the same must-not-mutate contract this stack pinned in the #4040 envelope work). An observer that retained and mutated it would corrupt the cached signed bytes used by later bundle aggregation. It now returns a defensive copy. Regression tests: a panicking observer still yields ErrSnapshotConflict from the protocol path; mutating the evidence envelope bytes leaves the snapshot's cached Marshal output intact.

This is the interim measure scheduled in the gates-doc decision log. The signing retry loop reports every terminal attempt outcome (minority readiness after completed announcement, failed protocol run, failed done-check exchange, or success) through an optional reporter; mechanical iterations that never sample the group (block-timing skips, local announcement errors, context cancellation) are deliberately not reported. Exactly one local signer per wallet reports, so a node records one observation per network-wide attempt. Outcomes feed a process-wide rolling window (50 attempts, shared across wallets via the PerformanceMetrics instance) exporting three gauges: signing_attempt_rolling_success_rate, signing_attempt_rolling_sample_count, and signing_attempt_implied_f_alert (1 when the full window's rate is below 0.14, between the f=2 expectation 0.238 and the f=3 expectation 0.114 of the Annex B sampling model; ~4% false-alarm at f=2, ~64% detection at f=3 per independent window). Operator guidance and threshold-tuning caveats are documented in the rollout adoc; Annex B now points at the implementation.

The enforcement runs at the end of RegisterNativeExecutionAdapterForBuild and covers the whole failure family: config-install failure, engine-registration failure after a successful install, and a binary built without frost_native (which can never honor the demand). Env-fallback mode (path unset) keeps the safe-by-default degrade posture unchanged. The checks are positive (native adapter + FFI executor actually registered), not merely error-presence, because later registration legs reset LastNativeRegistrationError and could mask an earlier failure. Fatality is deliberately not profile-conditional: an unreadable config file cannot reveal its profile and a missing profile means production (production-by-omission), so path-set is the only non-circular trigger.

The surrounding orchestration (Phase 6.3 executor-adapter entry, error taxonomy, Phase 7.1 bundle production, Phase 7.2 bundle-consuming selector) shipped with it. The two open exit items (legacy evaluator deletion, build-tag removal) are explicitly re-stated as gated on Phase 7's manifest flip, with the legacy evaluator's surviving caller identified as the deliberate rollback path. The FROST readiness manifest gets its home in keep-core (docs/development/frost-readiness-manifest.adoc): it was planned for the tBTC monorepo's docs/operations/ directory, but the monorepo signer is retired and keep-core is canonical, so Phase 7's flip target now exists in this repository. Both gates (ROAST retry, transition evidence) are recorded missing-no-go with explicit flip conditions: Phase 6 shipped (met), real-testnet integration run (pending), verified FrostUniFFIV1 migration (pending). The rollout doc and the RFC's stale receive-loop drop-site references are repointed accordingly.

Byte-preservation (the point of the envelope) is pinned by tests: received bytes survive re-broadcast verbatim, a non-canonical encoding is preserved, key-path and script-path roots round-trip, and Validate rejects malformed packages. proto generated with protoc-gen-go v1.36.3 into the existing gen/pb dir (no new Dockerfile gen-allowlist entry). Coordinator signing/distribution and member-side authentication (elected-coordinator check, signature verification, root binding) + retention + the context-bound member-authenticated share submission follow on this branch; the engine never sees this envelope (blame adjudication is Go-side).

Begin the tag with byte 0x00 (an illegal protobuf tag, field 0) so the signed payload is undecodable as any protobuf message: a signing-package signature is rejected when another envelope decodes the forged body, and another coordinator-signed message's signature (over a body starting >= 0x08) can never verify against domain||body. The test now asserts undecodability, including a body that embeds a full valid transition body. P2: Unmarshal reset bodyCache and wireEnvelope but not signaturePayloadCache, so a reused receiver could authenticate a freshly decoded package against stale signable bytes. Clear the cache on Unmarshal; test added. Proto SIGNED PAYLOAD note updated to the new tag bytes (file-level comment; generated .pb.go is unchanged).

Each signed body now prepends a UNIQUE domain tag to the bytes it signs and verifies, while the body that travels on the wire stays the bare serialized body. - Add localEvidenceSnapshotSignatureDomain + transitionMessageSignatureDomain, each beginning with byte 0x00 (an illegal protobuf tag, field 0) so the signed payload is undecodable as any protobuf message. This separates the domains in both directions without relying on field layout: a signature over one body cannot be accepted on another envelope (its decoder rejects the 0x00-leading body), and a genuine protobuf body starts >= 0x08 so its signature can never verify against domain||body. Matches the signing-package fix on #4056. - Split each type into bodyBytes() (the bare wire body) and SignableBytes() (domain || body). wireEnvelopeBytes / Marshal now embed bodyBytes(), and both Unmarshal reset the signable-bytes cache so a reused receiver never verifies against stale bytes. Rename signedBody -> bodyCache; add signaturePayloadCache. Sign and verify both flow through SignableBytes(), so the change is transparent to the sign sites and the wire envelope structure is unchanged. It DOES change the bytes signed, so signatures are not compatible with the pre-change protocol - all nodes must run the new code together (acceptable pre-mainnet; the external-audit gate stands). Tests pin the domain tagging, undecodability, prefix-free distinctness, bare wire body, and the reused-receiver cache reset.

Regenerated pb.go. - Codex P2: Validate now caps submitter_signature at MaxOperatorSignatureBytes, matching the other ROAST envelopes (an over-cap-but-under-envelope-cap signature previously reached verification/retention). - Gemini P1 (binding): keep signing_package_hash bound to the SignedSigningPackage ENVELOPE (Gemini affirmed - ties the share to the exact branch each member received); documented that this assumes canonical / non-malleable operator signatures, else the Phase 7.2b-4 blame layer must compare package bodies. Tests: round-trip asserts coordinator_id; validate-rejects adds zero / out-of-range coordinator + oversize submitter signature. Full pkg/frost/roast suite passes under -race.

AuthenticateShareSubmission used the truncating SubmitterID() accessor (uint32 -> uint8) and bytes.Equal without first enforcing structural validation, so a manually-assembled submission with submitter_id=259 signed by member 3 would authenticate AS member 3 (attribution confusion / dedup bypass), and empty live + sub hashes could pass via bytes.Equal(nil, nil). Call Validate() at the top of AuthenticateShareSubmission - it enforces 32-byte hashes, in-range member ids, and a present share before any field is trusted. Apply the same guard to AuthenticateSigningPackage (the merged sibling shares the identical truncating-accessor pattern) so both authentication boundaries are uniform. Tests: out-of-range submitter_id / coordinator_id rejected before verification, for both functions. Full pkg/frost/roast suite passes under -race.

An unsigned re-encoding of the same (body, signature) - which SigningPackage.Unmarshal deliberately preserves - changes an envelope hash without being equivocation, letting a MitM frame an honest coordinator and fragmenting share bindings across members. Switch the package identity to the BODY hash for BOTH the share binding (signing_package_hash) and the collector's equivocation detection. SigningPackage.EnvelopeHash -> BodyHash (sha256 of the signed body, stable across envelope re-encoding); proto + struct docs updated. - Defensive copy: Round2Collector.RecordSigningPackage retains a collector-owned copy of the package envelope, so a caller reusing the SigningPackage (receive-loop Unmarshal) cannot mutate the retained blame evidence. - Also hardens the two-phase lock: re-check the binding's elected coordinator after re-acquiring (prune + re-begin TOCTOU). Tests: body hash stable across an envelope re-encoding; the collector treats a re-encoded same-body package as idempotent (not equivocation) and retains its own copy across caller mutation.

Identity is the share BODY hash, so an unsigned envelope re-encoding is idempotent rather than a false conflict (the body-hash lesson from the package side). Retains a collector-owned envelope copy; nil-guarded; re-checks the binding after re-acquiring the lock. - ShareSubmission.BodyHash() added (sha256 of the signed body). - round2Record.shares now keyed to an owned round2ShareRecord{bodyHash, envelope}. Tests: authenticated retain + idempotent re-record; rejections (nil, unknown attempt, no package, non-member, wrong package); member-equivocation evidence; re-encoded same-body share idempotent. Full pkg/frost/roast suite under -race. The round-2 sign/distribute/authenticate/retain surface is now complete; next is 7.2b-3 (mirror FFI culprits) + 7.2b-4 (f+1 quorum blame compare).

Per attempt, for each candidate against the authoritative package: - accepted retained share that re-verifies INVALID -> RejectEntry (the observer holds the member's operator-signed share: self-incriminating, independently checkable; feeds NextAttempt's existing f+1 establishment gate). - accepted share that re-verifies VALID (yet flagged) -> nothing: not self-incriminating under this observer's package; coordinator-directed faults are a SEPARATE path (7.2b-4b), never inferred here. - divergent share only -> nothing (NEUTRAL: possible targeted coordinator equivocation, must not alone exclude). - no retained share / indeterminate re-verification -> nothing (fail closed). FROST share re-verification is engine-backed (Go has no native FROST share crypto - the collector's SignatureVerifier checks operator sigs, not the share equation): the new Round2ShareVerifier interface is that seam, injected so this lands and reviews now with a fake verifier; the engine-backed impl wires in with the interactive orchestration. Reuses the existing reject category + ExclusionAccuserQuorum/NextAttempt f+1 machinery; ConflictEntry stays reserved for self-conflicting bytes. Deterministic output (deduped, ascending by member, Count 1). Retained bytes are snapshotted under the collector lock; re-verification runs lock-free. Design converged via Codex+Gemini consultation.

A Go FFI bridge would naturally map a Rust/FROST deserialization error to a Go error, which the classifier read as "indeterminate -> don't blame", letting that cheater dodge a RejectEntry. Replace it with an explicit ShareVerificationResult tri-state (ShareValid / ShareInvalid / ShareIndeterminate): ShareInvalid covers both a mathematically invalid share AND undecodable member bytes; ShareIndeterminate is reserved for failures that are NOT the member's fault. The classifier blames ONLY ShareInvalid - everything else, including any future verdict, fails closed.

Retain the first conflicting package and surface the equivocation via a new CoordinatorConflicts(attemptContextHash) ([]ConflictEntry, error) as a ConflictEntry against the coordinator - the observer's input to LocalEvidenceSnapshot.Conflicts -> NextAttempt's f+1 establishment gate, which permanently excludes (and thereby auto-rotates) an established equivocating coordinator. Symmetric with 7.2b-4a's ClassifyCandidateCulprits: the collector produces accusation entries; the (still-unbuilt) orchestration wires them to the snapshot. No re-verification is needed - both conflicting packages were authenticated before the conflict was flagged, so it is unforgeable, self-incriminating proof. Catches only equivocation THIS observer directly received (the rare broadcast case). Targeted/split equivocation (different packages to disjoint members, so no single observer sees two) needs cross-observer comparison - Phase 7.2b-4b-ii, under a separate Codex+Gemini design consultation.

Routing the proof through f+1 lets a coordinator equivocate to <= f members and escape. - The proof must be the FULL coordinator-signed package envelope, not a hash+signature: the coordinator signs domain || body, so a verifier needs the body to check the signature AND the embedded attempt_context_hash (a hash+sig pair is replayable to frame an honest coordinator).

Layer 2 of the proof-carrying 4b: members publish the coordinator-signed package envelope(s) they accepted (the authoritative one, plus a second body-different one on local equivocation) so NextAttempt (PR3) can verify + dedupe by body hash + instant-exclude a coordinator that signed >= 2 distinct bodies for one attempt. The proofs travel verbatim like the other evidence bytes; a proof-free snapshot encodes exactly as before (backward compatible). No verification here.

With snapshots now carrying up to 2*MaxSignedSigningPackageBytes of coordinator package proofs, an adversary could make proto.Unmarshal allocate for a multi-hundred-MB garbage envelope before Validate's per-field caps fire. Add MaxSignedLocalEvidenceSnapshotBytes (proofs + operator sig + 64 KiB evidence/ framing allowance) and MaxSignedTransitionMessageBytes (a full bundle of those + coordinator sig), and reject oversized envelopes at the top of both Unmarshal paths before decoding. The transport layer remains the tighter primary bound; these are finite pre-allocation backstops matching the rest of the wire stack.

Additive: no caller yet (mirrors how the engine export landed before its Go caller). - cgo: tbtc_verify_signature_share typedef + dlsym wrapper + call helper, mirroring tbtc_signer_aggregate. - buildTaggedTBTCSignerEngine.VerifySignatureShare(sessionID, signingPackage, signatureShare, memberIdentifier, taprootMerkleRoot) -> tri-state verdict, with request/response marshalling + decoding helpers. - NativeShareVerificationVerdict tri-state with Indeterminate as the ZERO value, so an unset value / decode failure / FFI-transport error all fail closed against false blame. BLAME-SOUNDNESS: the request builder deliberately does NOT reject empty/short signing-package or signature-share bytes. For this operation those bytes are the SUBJECT of the engine's verdict: a member's retained share envelope can carry empty/garbage inner FROST bytes (the collector authenticates the operator signature, not the FROST equation), and the engine maps such bytes to `invalid` (blame). A bridge-side rejection would surface as an FFI error the Go host maps to ShareIndeterminate, letting a cheater dodge blame. Only the sessionID routing key is validated; package/share/member-id pass through for the engine to classify (malformed -> indeterminate, never false blame). Tests: payload builder (fields, taproot variant, empty-session rejection, pass-through of empty blame-subject bytes) and verdict decoder (valid/invalid/ indeterminate, unrecognized -> error + Indeterminate). Builds clean under default, frost_native, and frost_native+frost_tbtc_signer+cgo; full signing suite + vet + gofmt green. Follow-up (PR 2b): the concrete Round2ShareVerifier that unwraps the retained envelopes, binds session/taproot, calls this method, and maps the verdict to roast.ShareVerificationResult, plus interface wiring + fakes.

Design from a Codex+Gemini consult (strong convergence): - EngineRound2ShareVerifier in pkg/frost/signing (frost_native), depends on a narrow Round2ShareVerifyingEngine interface (segregation) so it is unit-tested with a one-method fake, no cgo. NativeTBTCSignerEngine gains VerifySignatureShare (so the registered engine satisfies it); 3 fakes updated. - Bound to ONE attempt via Round2ShareVerificationBinding{SessionID, AttemptContextHash, TaprootMerkleRoot}. The engine resolves the group key from sessionID and tweaks by the root; it cannot tell a valid-but-WRONG session/root from the right one, so a mis-bound verifier would turn an honest share into FALSE blame. VerifyRetainedShare checks the retained package's own AttemptContextHash and TaprootMerkleRoot against the binding BEFORE calling the engine, refusing (Indeterminate) on mismatch - it does not rely on the f+1 quorum to paper over mis-binding. (sessionID itself can't be self-checked; the construction site must supply one consistent with the attempt - a hard contract, enforced later by orchestration.) - Fail-closed against blame: submitter 0, unparseable package/share envelope, attempt/root mismatch, share-submitter-id mismatch, engine error, and any unrecognized verdict map to ShareIndeterminate without (for the pre-engine cases) calling the engine. Only the engine's `invalid` verdict yields ShareInvalid. Envelope-unmarshal failures are Indeterminate because retained envelopes are collector-authenticated re-marshals (the member controls only the inner FROST bytes, which DO pass through and become ShareInvalid when garbage). Added beyond the consult: a share-submitter-id guard (never verify one member's identity against another's bytes). - Hygiene: constructor errors on nil engine / empty sessionID and copies the root; immutable + concurrency-safe; warns on anomalous Indeterminate (never raw bytes); no operator-signature authentication here (collector's job, Q1). Compile-time assertion that it implements roast.Round2ShareVerifier. Construction site (live sessionID/taproot supply during a real signing session) is deferred to the not-yet-built interactive orchestration; the compiler prevents dead-code drift since the interface is already consumed. Tests (fake engine): verdict mapping, key-path nil root, engine error -> Indeterminate, every fail-closed-without-calling-engine case, constructor copies the root, nil-engine / empty-sessionID rejection, and argument capture. Builds default / frost_native / cgo; signing suite + vet + gofmt green.

My local validation missed it: I only tested ./pkg/frost/signing, and `go build ./...` skips _test.go files. Fixed both fakes; now validated repo-wide with `go vet -tags frost_native ./...` (the only remaining warning is a pre-existing tecdsa copylocks lint, unrelated here). Self-review fold (Medium): VerifyRetainedShare now checks the retained share commits to the bound package - bytes.Equal(sub.SigningPackageHash, pkg.BodyHash()) - before calling the engine, returning ShareIndeterminate on mismatch. This is the share<->package analogue of the submitter-id guard and the most direct false-blame guard at this layer: it prevents verifying a share against a package it never committed to (which would make an honest member's share fail -> false ShareInvalid). The collector only accepts package-bound shares, so it is a defensive cross-check that keeps the verifier sound for any caller. Added a test case (share commits to a different package -> Indeterminate, engine not called) and refactored the test helpers so a share commits to the same package the verifier is bound to. Gates: default + frost_native + cgo builds, signing suite, pkg/tbtc vet, repo-wide frost_native vet, gofmt all green.

Bridges the hardened interactive engine FFI to Go so a later orchestrator can drive engine-held-nonce signing. Mirrors the #4069 VerifySignatureShare bridge pattern (typedef + dlsym wrapper + call helper + marshalling). Adds to buildTaggedTBTCSignerEngine (concrete, build tag frost_native && frost_tbtc_signer && cgo): - InteractiveSessionOpen(sessionID, member, message, keyGroup, threshold, taprootMerkleRoot, attemptContext) -> {sessionID, attemptID, idempotent} - InteractiveRound1(sessionID, attemptID, member) -> commitments bytes - InteractiveRound2(sessionID, attemptID, member, signingPackage) -> share bytes - InteractiveSessionAbort(sessionID, *attemptID) -> {sessionID, aborted} Plus the request/response structs, a NativeInteractiveAttemptContext input type (+ session-open/abort result types) in the frost_native engine file so the orchestrator can reference them without cgo. Secret nonces never cross this boundary (engine-held, keyed by session+attempt) - the caller exchanges only public commitments, the coordinator's signing package, and shares. ADDITIVE: no Go caller yet, and the NativeTBTCSignerEngine interface is NOT widened (methods land on the concrete engine only), so no fakes change - repo- wide `go vet -tags frost_native ./...` stays clean. interactive_aggregate, whose failure path surfaces candidate culprits (needs a structured error carrying them), lands in the next PR. Tests: payload builders (fields, attempt-context marshalling, taproot variant, empty-input rejections incl. empty/zero attempt-context fields) + response decoders for all four. Builds clean under default / frost_native / frost_native+frost_tbtc_signer+cgo; signing suite + repo-wide frost_native vet + gofmt green.

Serializing the value unchanged meant the FIRST attempt (RFC 0 -> wire 0) would be rejected before round 1. Fix: InteractiveSessionOpen's request builder converts AttemptNumber+1 to the wire value (with a wrap/overflow guard) and documents NativeInteractiveAttemptContext.AttemptNumber as the 0-based value the bridge converts - so callers pass the natural attempt.AttemptContext value unchanged and cannot reintroduce the off-by-one. Test added: RFC attempt 0 -> wire attempt_number 1; the existing payload test now asserts wire = RFC + 1. Self-review fold: malformed-JSON / missing-field rejection tests for all four interactive response decoders (parity with the #4069 decoder-error test). Gates: signing suite, repo-wide frost_native vet, gofmt green.

InteractiveAggregate aggregates the responsive subset's shares for an attempt into the BIP-340 signature; the engine resolves verifying material from the session's own DKG state (no public key package crosses the FFI). The one non-mechanical piece: on a share-verification failure the engine returns the CANDIDATE CULPRITS in the error payload (ErrorResponse.candidate_culprits, u16 Go member ids, omitted for other errors), but the Go error envelope was code/message only. So: - add candidate_culprits to buildTaggedTBTCSignerErrorResponse + buildTaggedTBTCSignerStructuredError (additive; empty for every other error, so no behavior change elsewhere); - add a typed InteractiveAggregateShareVerificationError{SessionID, AttemptID, CandidateCulprits, Message}; InteractiveAggregate maps the aggregate_share_verification_failed code to it (session/attempt filled from the caller's request, which the payload doesn't echo). The runner errors.As it and feeds the culprits to the envelope-bound f+1 blame adjudication. The culprits are documented as PURE-CRYPTO candidates, NOT authoritative blame (a coordinator that aggregated honest shares against a substituted package/root would make honest shares appear here) - consistent with the engine + #4062. ADDITIVE: method on the concrete engine only (interface not widened; no fakes touched - repo-wide frost_native vet clean). Carries the wire u16 ids; PR3 converts u16 -> group.MemberIndex. Tests: payload builder (fields, rejections) + decoder (success/malformed) + interpretInteractiveAggregateError (share-verification -> typed error with culprits; other error -> passthrough preserving ErrNativeBridgeOperationFailed) + error-payload culprit extraction. Builds clean under default / frost_native / cgo; signing suite + repo-wide frost_native vet + gofmt green. (client-* CI does not build the cgo tags; validated locally.)

Adds MarkSucceeded(handle) to the Coordinator interface + inMemoryCoordinator: transitions a live (Collecting) attempt to Succeeded; returns ErrUnknownAttempt for an untracked handle and ErrAttemptStateInvalid for a non-Collecting attempt (fails closed like RecordEvidence/AggregateBundle rather than masking a caller bug). Any node may mark its OWN attempt succeeded - success, unlike AggregateBundle, is not coordinator-only. The runner (next PR) calls it on a successful aggregate; the cleanup's existing state == Collecting guard then skips, closing the bug. Updated the state-machine doc (Collecting branches to Succeeded directly on success, or Aggregating -> Transitioned on failure) and the 3 Coordinator test fakes (frost_roast_retry tag). Interface widening validated repo-wide via `go vet -tags "...frost_roast_retry" ./...` (no other implementers). Tests: Collecting -> Succeeded (State reflects it); unknown handle -> ErrUnknownAttempt; non-Collecting (double-mark) -> ErrAttemptStateInvalid. Go-native (roast), so the standard CI builds + tests it. Default build + repo vet + gofmt + roast suite green.

No runner orchestration logic yet - the happy path lands next. ActiveRoastAttempt: the immutable single-source-of-truth binding for one attempt {sessionID, context, contextHash, handle, electedCoordinator, taprootMerkleRoot, dkgGroupPublicKey}. NewActiveRoastAttempt enforces the consistency assertions that keep blame sound - sessionID==ctx.SessionID, ctx.Hash()==handle.ContextHash(), elected coordinator taken AUTHORITATIVELY from coordinator.SelectedCoordinator, non-empty dkg group key - and copies the root + dkg key so the binding is immutable (NextAttempt must derive every attempt's seed from the SAME dkg group public key bytes). A mis-bound session/root would make the engine verify honest shares against the wrong material -> false blame, so it is validated once here and then frozen. RunnerBus: the typed broadcast mesh (Broadcast + per-type receive streams for commitments/package/share/snapshot/bundle) with an in-process implementation for tests. CRITICAL dedup semantics (Codex consult): dedup ONLY byte-identical retransmissions (per-subscriber seen-set keyed by FULL message content hash); body-different messages from the same sender are NEVER suppressed, because for signing packages and shares a body-different duplicate IS equivocation evidence the collector must see - deduping by (attempt, sender) would silently drop it and defeat the 4b proof-carrying mechanism. Tests: ActiveRoastAttempt construction + each hard-assertion rejection + immutability of the copied root/dkg-key; bus typed routing, exact-retransmit dedup, body-different-duplicate delivery (the equivocation case), and late-subscriber isolation. Passes under -race. frost_native suite + gofmt + repo-wide frost_native vet green. (client-* CI builds default tags, not frost_native; validated locally.)

AttemptContext.AttemptSeed = SHA256(dkgGroupPublicKey || sessionID || messageDigest), and the same key later feeds NextAttempt's retry-seed derivation, so a different (non-empty) key would bind ctx's hash (key A) to retry material from key B and diverge subsequent attempts. Now re-derive attempt.DeriveAttemptSeed(dkgGroupPublicKey, sessionID, ctx.MessageDigest) and reject a mismatch against ctx.AttemptSeed. - Context immutability: context was stored as a shallow copy and Context() returned it, so a caller could mutate ctx.IncludedSet / ExcludedSet / TransientlyParked and make Context().Hash() drift from the pinned ContextHash(). Now cloneAttemptContext deep-copies those three slice fields on construction AND on Context() return - matching the root/dkg-key copying so the binding's immutability is honest. Tests: callers now pass the bound testDkgGroupPublicKey; added a "dkg key mismatch" rejection case (non-empty wrong key -> seed mismatch). frost_native suite + -race + gofmt + repo-wide vet green.

Design (consult + the #4075 slice-aliasing lesson): - Subscribes to the bus in the CONSTRUCTOR (before any Run broadcasts) so a node never misses a peer's first message; the harness constructs all nodes before starting them. - Every engine/collector input derives from the immutable ActiveRoastAttempt binding, never from peer messages; the node records its OWN share explicitly (no bus self-echo); envelope/payload bytes are copied at the boundary. - Elected coordinator from the binding; exactly that node builds+signs the package, everyone authenticates+retains it via the collector (Q1 boundary). - Package built from the whole responsive included set, so the aggregate needs a share from each (silent-member subsetting is the retry path's concern). Fake-engine + fake-bus harness test: N=3 run concurrently to a successful aggregate; each emits the signature and transitions its attempt to Succeeded. Passes under -race; frost_native suite + gofmt + repo-wide vet + default build green. (Fake-ignored placeholders - FROST member-identifier encoding, attempt-context fingerprint/id - are finalized at cgo wiring; the runner drives rounds with the attempt id the engine returns.)

Previously it accepted any sender and keyed by the envelope's SubmitterID, so a node could fill an honest member's slot with garbage, drop their real share, and get them falsely blamed. - obtainSigningPackage (Gemini P1 DoS): non-coordinators now loop and accept ONLY the elected coordinator's package for this attempt; a garbage package from any node previously aborted the honest run before the real one arrived. - Root-divergence refusal (Codex P1): after RecordSigningPackage retains the package, refuse (sign nothing) when its taproot root diverges from the bound session root - signing Round2 against it would sign for the wrong tweak; the retained package is blame evidence. - Attempt isolation (Codex P2): all three collection points now ignore messages whose msg.Attempt != the bound context hash (the bus may carry concurrent or stale attempts). Tests: adversarial e2e (a garbage package from a non-elected sender + a share from a non-included member, pre-injected, are ignored and the honest run still succeeds) + a constructor-rejection table (my self-review Low). Happy path + -race + frost_native suite + gofmt + repo vet + default build green.

P1 (message-vs-digest binding): the constructor accepted a free-standing `message` parameter and only rejected empty input. A caller whose message diverged from the digest the attempt is bound to (ActiveRoastAttempt's MessageDigest, which the package/share envelopes commit to via the attempt hash) could have the runner open the session and FROST-sign those bytes, marking an attempt for digest A succeeded with a signature over digest B. Remove the parameter entirely and derive the signed message from the binding's MessageDigest, so the runner can never sign a message inconsistent with the attempt it is bound to. P2 (abort native attempts on early exit): once InteractiveSessionOpen succeeds the engine holds the attempt's secret nonces/session state. If Run returned early (ctx cancel, or an error before round 2 consumed the nonces) that material stayed resident. Add InteractiveSessionAbort to the engine boundary and defer a best-effort abort, suppressed only on a clean success. Tests: drop the removed "empty message" construction case; add an early-exit test (ctx expires while collecting commitments) asserting exactly one native abort fires. frost_native suite green under -race; gofmt + repo frost vet clean.

The prior fix retained a sender's body-different share only while collectShares was still collecting. But the loop exits the instant len(into) == len(included), so a duplicate queued BEHIND the share that fills the final slot was never read, never recorded, and then lost when Run aggregated and pruned - the same gap the coordinator-package path already closes with a post-return drain. Extract recordShareMessage (validate -> retain -> count first-accepted) and call it from both the collection loop and a non-blocking, buffer-bounded drain that runs once `into` is full, so queued member-equivocation evidence reaches the collector before aggregation/prune. Test: RetainsQueuedShareEquivocationAfterCollection - member 2's first share fills the final slot and its body-different duplicate is queued right behind it; the conflict is still emitted (EquivocationKindShareConflict, member 2) and the first share is still the counted one. frost_native signing suite green under -race; gofmt + vet clean.

The share-drain and recordBufferedCoordinatorPackages both used a receive-until-empty loop (for { select { case <-stream; default: return } }). That only terminates when the channel is observed empty, so a peer that keeps the stream non-empty - e.g. flooding body-different share submissions - starves the default branch, and the loop neither finishes nor observes ctx. Run then hangs instead of aggregating even though enough valid shares were collected: a liveness DoS. Bound both drains to the queue length at entry (for i, n := 0, len(stream); ...). They still retain every duplicate already buffered behind the slot-filling envelope, but a flood arriving DURING the drain is not processed (late arrivals are the blame path's concern), so the drain always terminates promptly.

The conclusion defer pruned on every non-success exit. But failure paths retain signed evidence the blame/retry path must read: the root-divergence return fires AFTER RecordSigningPackage, and (once it lands) an aggregate share-verification failure leaves the recorded package/shares. Pruning there made CoordinatorPackageProofs / ClassifyCandidateCulprits report ErrRound2UnknownAttempt, losing the proof just retained. (This over-corrected the earlier prune fold, which only needed prune-on-success.) Split the defer by outcome: SUCCESS prunes the collector state (no blame/retry needs it); FAILURE / early exit aborts the engine session to drop resident secret nonces but leaves the collector intact for the caller to snapshot, propagate, and then prune. Test: PreservesEvidenceOnAggregateFailure - force every node's aggregate to fail after package/shares are recorded, then assert each collector still holds the attempt (a conflicting re-begin is rejected). Verified to FAIL under the old always-prune defer. Success-prune and early-exit-abort tests still pass. frost_native signing + roast suites green under -race; gofmt + vet clean.

Adds the Go cgo binding for the engine's new frost_tbtc_derive_interactive_attempt_context export, so the host obtains the canonical attempt context + FROST identifiers from the engine instead of re-deriving the domain-separated hashing in Go (the consult's Option B, single source of truth). Mirrors the existing InteractiveSessionOpen bridge: a C dlsym shim (tbtc_signer_derive_interactive_attempt_context + typedef), the request payload builder (0-based -> 1-based wire attempt-number conversion, overflow-guarded), the response decoder (1-based -> 0-based back; identifier mapping), the cgo call, and the buildTaggedTBTCSignerEngine.DeriveInteractiveAttemptContext method returning NativeDeriveInteractiveAttemptContextResult{AttemptContext, FrostIdentifiers}. Additive: no Go caller yet. The concrete engine gets the method now so that widening interactiveSigningEngine in the next PR (runner integration: coordinator cross-check + placeholder replacement + identifier threading) keeps the cgo build green. Production real-engine signing stays gated on the frost-secp256k1-tr =3.0.0 external audit; this is parse/serialization plumbing. Tests (structural, no .so needed - the real-FFI path skips when unlinked, like the sibling bridges): request payload builder (fields + 0->1-based) + input rejection + response decode (1->0-based + identifiers + malformed/zero-attempt rejection). gofmt + cgo build/vet/suite + frost_native build all clean.

Truncation at the auth boundary: Unmarshal cast the 4-byte sender_id straight to group.MemberIndex (uint8), so an out-of-range claim (e.g. 259) wrapped to a valid seat (3) and could pass IsValidMembership for whoever holds the wrapped seat - and round-1 commitments carry no inner signature to reject it later. Validate the raw uint32 is in [1, group.MaxMemberIndex] BEFORE the narrowing cast. Liveness: deliverNonBlocking recorded the content hash in `seen` BEFORE the non-blocking send, so a message dropped on a full stream was marked seen; the pkg/net retransmission after the stream drained was then suppressed as a duplicate - permanently losing a required message. Record `seen` ONLY after a successful enqueue (dedup-check + send + record now under one lock; the non-blocking send never blocks, so holding the lock across it is safe).

A message dropped on stream overflow is NOT recovered by a pkg/net retransmit - BroadcastChannel.Recv wraps the handler with retransmission support that filters already-seen sender/seqno BEFORE the handler runs, so a retransmit never re-reaches the bus. Relying on it could permanently lose a required commitment/share under overflow. A drop is therefore permanent, and blocking is unsafe (the runner drains streams in phases - blocking on a finished stream would stall the ones it still needs). So the correct guarantee is to size the streams above a whole attempt's HONEST message volume (<= one per included member per type + a small equivocation allowance the collector caps anyway; tBTC groups ~100 seats) so honest operation never overflows. Overflow can then only arise from a peer flooding distinct messages faster than the runner drains, degrading the attempt to a ROAST retry (pkg/net per-peer limits backstop it) rather than silently dropping an honest message. Bumped the per-stream buffer 256 -> 1024 and corrected the misleading "pkg/net retransmits anyway" comments at all four sites. The don't-mark-seen-on-drop behavior is kept as defensive dedup hygiene (a drop must not poison the set against a non-retransmit re-delivery) but is no longer described as a recovery path; the test is renamed DropDoesNotPoisonDedup with the accurate framing. frost_native build/vet/suite (-race) + cgo vet clean.

Adds a gated interactive signing path to the native FFI executor adapter: when the audit gate is on, an engine is registered, and ROAST orchestration is active for the session, the executor drives ONE interactive attempt via the merged runner/bus/engine pieces instead of the coarse primitive. Design follows the Codex+Gemini executor-wiring consult: - The existing tBTC signingRetryLoop owns retries; the executor drives a single attempt per invocation (no nested loop). - The runner replaces primitive.Sign only on the active interactive path; the coarse path stays as the fallback (side-by-side, gated rollout). - Engine injection via a package-level provider seam (fake in tests, cgo engine in production); a DISTINCT audit gate (KEEP_CORE_FROST_INTERACTIVE_SIGNING_ENABLED, default off) keeps the real engine dormant until the frost-secp256k1-tr audit clears, separate from the orchestration readiness gate. - Threshold comes from the persisted DKGThreshold, not DishonestThreshold+1. - Once committed to interactive signing, failures HARD-FAIL (no silent coarse fallback) to avoid fracturing the signing group. The drive lives under frost_native && frost_roast_retry (runner + orchestration registries both live); a no-op stub covers all other builds. Fake-engine tests cover the happy path (1-of-1, real decoded BIP-340 sig), each front-door fallback, and the runner-failure hard-fail. Deferred to follow-ups: production cgo engine registration (gated), the stable ROAST session-key plumbing + blame/evidence bridge (cross-attempt), and coarse-path retirement.

The drive looked the attempt handle up by SessionID (currentAttemptHandleForCollect), but SetCurrentAttemptHandleForSession keys by SessionID alone -- so concurrent seats overwrite each other's handle: two seats could MarkSucceeded the same handle, or a seat could fall back to coarse after another seat's cleanup while peers stay interactive. Fix (root cause, matching the consult's session-object shape): fold the drive into attemptRoastRetryOrchestrationFromRequest, which now drives the gated attempt with the handle BeginOrchestrationForSession returned for THIS Execute and returns (signature, cleanup, error). The drive takes the handle + attempt context as parameters -- no session-keyed lookup -- so each seat stays bound to its own attempt. The drive collapses to one frost_native file (no longer needs frost_roast_retry or a default stub; the entry's existing build-tag split already covers it). All four tag combinations build/vet/test green (default / frost_native / +frost_roast_retry / +frost_tbtc_signer cgo); -race clean.

That is intentional, not a bug: per the executor-wiring consult, production cgo interactive signing is deferred until the blame/evidence bridge + stable session-key plumbing land AND the frost-secp256k1-tr audit clears. Registering it now would let an operator enable a half-wired flow (retries without culprit exclusion, session-key trap unfixed). Document the deferral at registerBuildTaggedNativeFROSTSigningEngine -- where a reader of the new RegisterInteractiveSigningEngineProvider seam looks for the production wiring -- so the unreachable-in-production state reads as an intentional, gated rollout step rather than a forgotten call.

Makes ROAST retry actually consult the previous attempt's transition state (it silently always fell back to legacy before) via a STABLE, member-scoped session key and a unified transition record. Per the Codex+Gemini consult. The trap (verified): signingSessionID embeds the attempt number, so the transition bundle was stored under an attempt-specific key while the selector looked it up by fmt.Sprintf("%v", message) -- the keys never met. Codex found two more: cleanup cleared the handle before the selector could use it, and the selector passed a nil dkgGroupPublicKey (so NextAttempt derived a context NewActiveRoastAttempt rejects). Fix: - Add roastSessionID(message, root, startBlock), STABLE across attempts, beside the attempt-specific signingSessionID; thread it via signing.Request. RoastSessionID -> NativeExecutionFFISigningRequest and into AttemptContext.SessionID. The coarse path keeps the attempt-specific SessionID. - Replace the bundle registry with one RoastTransitionRecord{Bundle, PreviousHandle, PreviousContext, DkgGroupPublicKey} keyed by (roastSessionID, memberIndex): subsumes the key fix, the cleared-handle trap (record carries the handle), the nil-dkgkey trap (carries the key), and multi-seat keying (#4081). Cleanup populates it under the STABLE ctx.SessionID; the HANDLE registry stays keyed by the attempt-specific request.SessionID so the coarse receive-loop's binding validation + snapshot submission are unaffected. - signingParticipantSelector.Select gains a memberIndex param; the ROAST selector reads RoastTransitionForSession(roastSessionID, member) and feeds PreviousHandle/Bundle/DkgGroupPublicKey to EvaluateRoastRetryForSigning. Scope: PR2a delivers the coordinator/local-bundle (and single-node) retry path - a record is populated only for the seat that produces the bundle locally. Non- coordinator seats get it via PR2b's snapshot/transition bus exchange, which also wires the blame/evidence bridge. Production interactive signing stays gated until both land. All four tag combinations build/vet/test green (default / frost_native / +frost_roast_retry / +frost_tbtc_signer cgo); full pkg/tbtc suite green both builds.

selector consumes records P1: driveInteractiveRoastSigningIfEnabled passed request.SessionID (attempt- specific) into NewActiveRoastAttempt, but ctx.SessionID is now the stable RoastSessionID -> the sessionID != ctx.SessionID check rejected every gated interactive attempt before round 1. Bind to attemptCtx.SessionID (the interactive engine session is unified on the stable id). The drive test now uses request.SessionID != ctx.SessionID, mirroring production, so it exercises the fix. P2: the (session, member) transition record persisted after consumption, so a stale record (from attempt N, when this member is not the next attempt's elected coordinator and produces no fresh one) could re-drive a later retry with the wrong IncludedSet. The selector now consumes (clears) the record after reading it; absent a fresh record it falls back to legacy. New regression test asserts consume-on-read. All affected suites green (pkg/frost/signing 3 builds, pkg/tbtc frost_roast_retry); gofmt clean.

Change signingParticipantSelector.Select to return the included member indices ([]group.MemberIndex) instead of a qualified-operator address set the signing loop re-maps. The legacy selector now computes the indices internally (operator selection + per-member inclusion + surplus trim); the loop derives the excluded set as the complement. This is a behaviour-preserving refactor -- the full pkg/tbtc suite's excluded-set assertions are unchanged -- that removes the multi-seat precision loss of the address-based path (one ready seat qualified ALL of an operator's seats, including ones ROAST means to park/exclude) and lays the member-level seam the ROAST selector (PR2b-1b) will return its transition IncludedSet through.

Every local seat -- including ones excluded from an attempt -- now records a local "observe" binding for each attempt so it holds a coordinator-instance- local handle to (in later commits) verify the attempt's transition bundle and run NextAttempt for participant selection. An AttemptHandle is not portable across coordinator instances, so a receiver cannot use another node's handle. - pkg/frost/signing: an observe-attempt registry keyed by (roastSessionID, member, attemptContextHash) -> {handle, context, dkgGroupPublicKey}, plus ObserveAttemptForTransition which -- gated on the readiness opt-in and a registered coordinator -- builds the attempt context from the request, BeginAttempts a local handle, and stores the binding. No-op under the deterministic static conditions every honest node sees identically (opt-out, no coordinator, unextractable material). - pkg/tbtc: a per-signer roastTransitionController (nil in the default build and non-ROAST deployments) the signing loop drives via BeginObservedAttempt once per attempt, BEFORE the skip branch, with the exact member-level included/excluded sets selection produced. Constructed from loopCtx so the later commits can scope the bundle exchange to the session lifetime. INERT: the observe bindings are produced but not consumed. The failed-attempt snapshot/bundle exchange (C2) and member-level fail-closed consumption (C3) follow. Cleanup of consumed bindings + sweep wiring land with C2's listener; in the gated/dormant state (no coordinator registered) the registry does not grow. Single-seat-per-node scope; multi-seat ROAST retry stays rejected. Verified: gofmt; build+vet on default / frost_native / "frost_native frost_roast_retry" / "frost_native frost_tbtc_signer cgo"; observe + loop-wiring unit tests (incl. -race); full pkg/frost/signing (tagged) and full default pkg/tbtc suites green.

RoastTransitionExchange runs one signer's failed-attempt transition exchange over a RunnerBus: - a listener (session-lifetime ctx) records peers' evidence snapshots against the elected coordinator's observe handle (only the elected seat collects) and verifies + stores received transition bundles; - BroadcastForcedSnapshot publishes a forced empty proof-of-attendance snapshot (marshaled, then recorded OWN before broadcast so VerifyBundle's censorship check is meaningful); - AggregateAndBroadcast aggregates the collected snapshots into a coordinator-signed bundle, stores it via the same verify+store path receivers use, and broadcasts it -- a no-op on any seat that is not the elected coordinator. All binding lookups resolve the per-attempt observe handle (C1) by the snapshot/bundle's own SIGNED AttemptContextHash; the authenticated bus sender must match the claimed submitter/coordinator. verifyAndStore clears the consumed observe binding. Tested with a synchronous multi-node harness (capture bus + by-hand delivery): 3 seats broadcast forced snapshots -> the deterministically elected coordinator aggregates + broadcasts -> every seat ends with a verified transition record and a cleared observe binding; a non-elected seat produces no bundle/record. INERT: nothing constructs the exchange in production yet (part 2 wires it into the controller's OnAttemptFailed with the snapshot/bundle block deadlines and retires maybeProduceTransitionRecord as producer). Selector still legacy. Verified: gofmt; vet on default / frost_native / "frost_native frost_roast_retry" / "frost_native frost_tbtc_signer cgo"; full tagged pkg/frost/signing suite.

Still INERT -- the selector does not consume the produced records yet (C3). - ObserveAttemptForTransition returns the attempt context hash so the controller retains it for the failed-attempt drive. - The per-signer controller (frost_native && frost_roast_retry) now constructs the session-scoped exchange when ROAST retry is active (readiness opt-in + a registered coordinator + a usable wallet channel; nil otherwise) over a broadcast-channel runner bus scoped to loopCtx, and adds OnAttemptFailed: it publishes this seat's forced proof-of-attendance snapshot and spawns a goroutine that, at the snapshot deadline (timeoutBlock + cooldown), has the elected coordinator aggregate + broadcast the bundle -- off the retry-loop goroutine, bounded by loopCtx. The exchange is held behind a small interface so the controller's drive is unit-tested with a fake. - The signing loop calls OnAttemptFailed before the protocol-failure continue (only included seats reach it); signing.go threads se.waitForBlockFn through. - Observe bindings the seat does not consume per-attempt (a signing whose attempts all succeeded) are cleared at session end via the exchange listener's defer, so they do not leak (the failed-attempt path already clears via verifyAndStore; the TTL-sweep backstop wiring lands in C3 with the producer retirement).

The ROAST participant selector now CONSUMES the transition record the observe + bus exchange (C1/C2) produces, selecting the next attempt's included set at the member level. This is the one commit that changes signing behaviour (gated: frost_roast_retry build + readiness opt-in + a registered coordinator; legacy fallback otherwise, so dormant until the audit clears). - ConsumeRoastTransitionForSelection (pkg/frost/signing, frost_roast_retry): a three-way contract -- * fresh record -> NextAttempt(PreviousHandle, Bundle, threshold, DkgKey) -> return nextCtx.IncludedSet verbatim (member-level), with freshness (prev attempt + 1 == retry) and a derived-attempt cross-check; * initial attempt or ROAST inactive -> ErrRoastSelectionFallBackToLegacy (a UNIFORM legacy fallback every honest node makes identically); * a committed ROAST attempt expected a transition that did not arrive (or NextAttempt infeasible) -> a plain error, so the caller FAILS CLOSED. VerifyBundle is not re-run here (the listener verified before storing). - The ROAST selector dispatches: consume on success, legacy on the fallback sentinel, and surface any other error -> performMembersSelection returns it -> the retry loop terminates (the outer layer retries the whole signing). Never legacy on the fail-closed path: mixed ROAST/legacy selection across honest nodes is the fracture class. threshold = the group honest threshold (== the tBTC signing threshold t for the NextAttempt infeasibility check; the authoritative source if they ever diverge is the persisted DKGThreshold). Verified: gofmt; build+vet on all 4 combos; consume + selector tests (5 + 3); full tagged pkg/frost/signing; full tagged pkg/tbtc (minus the pre-existing failure). The default build does not compile this path (frost_roast_retry), so it is unchanged.

Foundation only -- behaviour-preserving until the parking is threaded from selection (the next commits). Codex's B1: ConsumeRoastTransitionForSelection returned only the next IncludedSet, dropping NextAttempt's TransientlyParked set, and BuildAttemptContextFromRequest dropped parking (nil) -- so a silence-parked (transiently-offline) honest member became permanently excluded and was never reinstated, monotonically shrinking the signer set toward infeasibility. This commit lays the carrier: - signing.Attempt gains TransientlyParkedMembersIndexes (a subset of the "not participating now" ExcludedMembersIndexes). - BuildAttemptContextFromRequest splits Excluded into permanent-excluded (Excluded - Parked) and the parked set, and calls NewAttemptContextWithParking with both instead of dropping parking, so NextAttempt can reinstate a parked member the attempt after. No producer sets TransientlyParkedMembersIndexes yet (the selector still returns only IncludedSet), so parking is empty and permanentExcluded == Excluded -- behaviour is unchanged. The selector struct + loop threading + the roastAttemptNumber decouple + lostRoastSync + done-check handling (B1 threading, B2, B3) follow. Verified: gofmt; build on default / frost_native / "frost_native frost_roast_retry"; context-builder / observe / consume / exchange / cleanup tests green.

B2 -- decouple the committed ROAST attempt index: signingRetryLoop now maintains roastAttemptNumber, a 0-based counter advanced ONLY when an iteration reaches selection/observe (a committed attempt). The block-timing, announcement, and minority-readiness skips that tick attemptCounter no longer advance it, so a skipped loop iteration does not break the consecutive-transition chain across honest nodes. The observe context, freshness check, and ConsumeRoastTransitionForSelection all key off roastAttemptNumber instead of attemptCounter-1. B1 -- thread the transient park through selection: ConsumeRoastTransition ForSelection now returns (included, transientlyParked, err); the new participantSelection struct carries both through the Select interface; the loop passes the parked set to BeginObservedAttempt, which stamps it on the observe Attempt so the attempt after a one-attempt park reinstates the parked members rather than excluding them permanently. The legacy selector never parks. Also makes cloneAttempt nil-preserving for the parked field so a clone compares DeepEqual to an attempt that never set it. Tests: TestConsumeRoastTransitionForSelection_CarriesParking (B1), TestSigningRetryLoop_SkipDoesNotAdvanceRoastAttemptNumber (B2).

The transition listener now flags lostSync when it receives a bundle for an attempt hash it NEVER observed (distinguished from a benign retransmit of an already-consumed attempt by a retained observed-history marker). The retry loop checks HasLostSync before selection and fails closed -- catching the lagging-node fracture the selector's local freshness check cannot (its roastAttemptNumber is behind, so a stale-but-consecutive record would mis-select). The bundle is authenticated but unverifiable for an unobserved attempt; that insider fail-closed surface is within 1b's accepted regression and is the blame bridge's concern (PR2b-2), documented at the site. B3 -- the observe handle stays in a collecting state after the drive handle's local success, so an elected coordinator could aggregate, and a peer's failure bundle could be stored, for an attempt that actually SUCCEEDED. OnAttemptSucceeded (wired right after a successful protocol round, before the done-check) clears the observe binding -- keeping the history marker -- so no failure transition is synthesized or stored for a won attempt. A subsequent done-check failure then finds no fresh record and fails closed (adjudicated to Codex: mark-succeeded + fail-closed over synthesizing a dishonest no-reject transition). Registry: add an observed-history map (lifetime-shared with bindings: cleared at session end, swept by the same TTL) + attemptEverObserved + exported ClearObservedAttemptOnLocalSuccess. Tests: lost-sync on unobserved bundle; retransmit of a consumed bundle does not trip lost sync; a succeeded seat stores no peer failure transition and does not false-trip lost sync; done-check-failure-after-success signals OnAttemptSucceeded and never OnAttemptFailed; lost-sync fails closed before selection; HasLostSync delegation; registry marker retain/clear semantics.

Safe today (NewAttemptContext- WithParking copies before sorting) but a latent footgun if any future context-build step mutates permanentExcluded in place.

That breaks the signing-round / transition-evidence correlation the blame bridge needs and leaves the coarse path electing a coordinator / deriving a session off a wall-clock counter that diverges across nodes with different skip histories. Resolution (the context-coherence core of the consult-locked Option B, adjudicated Codex over Gemini's interactive-only Option D; Gemini's anti-B "legacy topic collision" objection was a misread -- the re-key is strictly ROAST-gated): when ROAST retry is runtime-active, the loop keys the active signing attempt off the COMMITTED roast index. committedRoastAttemptNumber is captured BEFORE the per-attempt advance and used for both the observe binding (Number = committed+1) and the active attempt (number = committed+1), so the two AttemptContexts are byte-identical; the transiently-parked set is threaded through signingAttemptParams onto the active Attempt. signing.go's coordinator election, session id, and Attempt.Number inherit the committed identity for free (they already key off attempt.number). Gating is the new deterministic, group-wide signing.RoastRetryActive() (readiness opt-in AND a coordinator registered -- false in non-frost_roast_retry builds via the registration default stub), mirroring the observe step's own runtime gate so observe and active agree. The legacy / ROAST-inactive path is byte-identical to today (attemptCounter, no parking). DEFERRED (with reason): Option B's announcement session-id re-key. It is not needed for fracture-safety -- with the active context now committed-keyed, two co-announcing nodes on different roast numbers build different hashes and cannot co-sign (fail + retry, lostSync backstop) -- and it is double-edged on laggard liveness (isolating a laggard into its own announcement session can strand it on an old roast number), the exact battle-tested sync point Gemini flagged. The done-check stays attemptCounter-keyed intentionally: a laggard receiving the majority's valid signature via the wall-clock done-check is benign and helps liveness. Tests: ActiveAttemptUsesCommittedRoastNumber (skip makes attemptCounter=2 diverge from the committed number 1 -> active uses 1); ActiveAttemptUses AttemptCounterWhenRoastInactive (legacy unchanged); RoastRetryActive gating.

Add TestSigningRetryLoop_ActiveAttempt CarriesParking: an injected selector parks member 3, and the test asserts the parked set reaches signingAttemptParams. A regression dropping the field would make a one-attempt park permanent on the active path (the B1 hazard). - Attempt.Number's doc still said "1-based signing attempt counter"; under active ROAST it carries the COMMITTED roast number (can be < the wall-clock count after skips). Clarify so a future caller does not assume wall-clock semantics. Accepted-not-folded (documented in the review): the per-call env read means an operator flipping KEEP_CORE_FROST_ROAST_RETRY_ENABLED mid-signing can desync the active gate within one signing -- liveness-only (SessionID/context-hash firewalls), operator-debugging trigger, consistent with the env's documented per-call semantics. Coarse split-quorum under coordinator equivocation is the PR2b-2 blame bridge's domain. Done-check staying attemptCounter-keyed is benign and confirmed beneficial (a laggard finalizes the majority's valid signature).

Fix: add a build-tagged roastTransitionProducerAvailable() (true only under frost_native && frost_roast_retry; default-stub false), and require it in both RoastRetryActive() and the selector's active gate. Without a producer ROAST is inactive -> legacy fallback, never fail-closed. Behavior-preserving in the production target (frost_native && frost_roast_retry: the producer is always present, so RoastRetryActive stays readiness AND coordinator, and the fail-closed discipline is unchanged). roastTransitionProducerAvailable is a build constant, so it is uniform across a correctly-deployed group. This also resolves the build-tag asymmetry three reviewers flagged (the committed-number active-attempt switch could fire in a frost_roast_retry-only build with no observe context to match): RoastRetryActive is now false there, so the active attempt stays on the legacy attemptCounter. DEFERRED (Codex P2-2, per the locked plan): the transition exchange binds one deps.Coordinator/SelfMember, so a multi-seat operator's non-elected seats cannot aggregate -> next retry fails closed. That is the documented PR2b-1.5 multi-seat increment (per-seat deps); the rollout gate must reject multi-seat wallets until then. Not introduced by this PR. Tests: FallbackWhenNoProducer (frost_roast_retry && !frost_native -> legacy, not fail-closed); RoastRetryActive gating now asserts == producer availability. The frost_native fail-closed tests are unchanged (producer present).

They still run + assert in frost_native && frost_roast_retry; the no-producer legacy-fallback path is covered by the dedicated TestConsumeRoastTransitionForSelection_FallbackWhenNoProducer. Root cause of the miss: my test-build matrix ran default + "frost_native frost_roast_retry" + cgo, but not frost_roast_retry-only -- exactly the build whose behavior the producer-gate changed. frost_roast_retry-only is now part of the verification matrix; it passes (pkg/tbtc 146.7s, pkg/frost/signing ok).

A multi-seat operator runs one signer goroutine per local seat, but ROAST deps were registered ONCE process-wide with a Coordinator bound to a single SelfMember; whichever local seat is the elected ROAST coordinator for an attempt could only aggregate if it happened to be deps.SelfMember, else AggregateBundle returned ErrNotAggregator -> no transition bundle -> the next retry fail-closed. This commit replaces the single registry slot with a per-member map and adds the per-seat API, WITHOUT changing single-seat behavior (the call-sites still use the legacy helpers; commit 2 threads the per-member ones through): - roastRetryRegistrationByMember map[MemberIndex]RoastRetryDeps - RegisterRoastRetryCoordinatorForMember(member, deps) -- enforces deps.SelfMember == member (the coordinator is bound to deps.SelfMember at construction, so a mismatch would let it aggregate as the wrong seat; rejected) - RegisteredRoastRetryCoordinatorForMember(member) - RoastRetryActiveForMember(member) (readiness AND producer AND this member registered) -- per-seat activation so an unregistered seat stays on legacy rather than fail-closing - back-compat: RegisterRoastRetryCoordinator(deps) registers under deps.SelfMember; RegisteredRoastRetryCoordinator()/RoastRetryActive() keep the legacy "any registered" semantics (single-seat unchanged; the ~20 existing callers + default-build stubs are untouched) Single-seat is byte-identical (legacy wrapper round-trips one entry). Per-member overwrite/coexist, self-member-mismatch rejection, and per-member activation are tested; full signing suite green in all three producer states + -race.

The highest-value finding was a real miss: the multi-seat acceptance test was VACUOUS -- for its context the elected coordinator is member 1 (= the legacy process-default SelfMember) and it only built the elected's exchange, so it passed even against the pre-fix shared-coordinator code. - Rewrite TestRoastTransitionExchange_MultiSeatElectedSeatAggregates: build an exchange + observe binding for EVERY local seat from its OWN per-member deps, then assert (a) the elected seat aggregates with its own coordinator (record + one bundle) AND (b) the NON-elected siblings do NOT aggregate (no bundle). (b) is the non-vacuous half: pre-fix all seats shared one coordinator bound to the elected member, so a sibling's AggregateBundle would have run as the elected member and broadcast a bundle; per-member coordinators make it ErrNotAggregator.

Gemini approved; Codex found 3 P2s -- P2-1 is a real fracture I introduced when threading per-member deps. P2-1 (partial-activation fracture): commit 2 made the SELECTOR's activation gate per-member (RoastRetryActiveForMember). A multi-seat operator with member A registered and member B not would then drive A via the transition (ROAST) and B via the legacy shuffle for the SAME attempt -> divergent included sets -> fracture. The legacy-fallback sentinel is only safe when UNIFORM. Fix: the selector's ROAST-vs-legacy decision is now PROCESS-level (RoastRetryActive, any-entry), and a missing per-member coordinator (partial registration -- a wiring bug) FAILS CLOSED, never legacy (a legacy fallback for the unregistered seat while a sibling selects from the transition would split the included set). The per-member loop/observe gates stay as-is: an unregistered seat cannot observe and fails closed at the selector, so it never selects a divergent set. P2-2 (stale deps on reject): RegisterRoastRetryCoordinatorForMember now DELETES any existing entry when it rejects a registration (member 0 or SelfMember mismatch), so a bad re-registration deactivates the seat (fail-safe to legacy) instead of leaving stale deps active. P2-3 (coarse submitSnapshotIfActive any-entry): NOT folded -- pre-existing Phase-4 coarse evidence path (the session-keyed handle registry is not member-keyed, and no live binding producer is wired, so it is inert). A partial fix (per-member coordinator only) would pair it with a still-session-keyed sibling handle and be worse; the full fix needs the session-handle registry member-keyed too -- a separate scope and a coarse-path prod-wiring prerequisite. Gemini concurred it is out of scope here. Tests: PartialRegistrationFailsClosed (member 1 registered, select member 2 -> fail closed, not legacy); RejectDropsExistingEntry.

Only the cgo `frost_tbtc_signer` resolver carries that guard; the non-cgo `frost_native` resolver permits it (transitional build -- the deeper native_ffi_primitive guard refuses scaffold material at signing time instead). So the test failed under any non-cgo frost_native build. - TestUnmarshalSignerMaterialFromPersistence_LegacyEncodingResolvesNativeMaterialOnFrostNativeBuild - TestSignerMarshalling_LegacyRoundtripMigratesToNativeEnvelopeOnFrostNativeBuild assert legacy->native resolution SUCCEEDS without opt-in -- the permissive non-cgo behaviour. So they failed under the cgo combo (resolver refuses). Re-tag each test to the build whose resolver contract it exercises, mirroring the resolver files' own tag split (signer_material_resolver_build_frost_native.go vs signer_material_resolver_build_frost_native_tbtc_signer.go): - move the refusal test into a new cgo-tagged file (`frost_native && frost_tbtc_signer && cgo`); - tag the migration tests `frost_native && !(frost_tbtc_signer && cgo)`.

For a multi-seat operator that registered some but not all seats, the unregistered seat would then run the coarse/legacy primitive while registered sibling seats drive bound ROAST messages -- mixed bound/unbound for the same attempt, a group fracture (Codex re-review of #4085). The legacy-fallback sentinel is only safe as a UNIFORM, group-wide decision: i.e. when NO seat is registered anywhere (registeredRoastRetryMemberCount() == 0). When a sibling seat IS registered, advertising the fallback for an unregistered seat is non-uniform within the operator and fractures the attempt, so fail CLOSED with a non-sentinel error (the dispatcher treats it as terminal and aborts Execute rather than falling through to coarse). Also fail closed for FULLY-registered multi-seat (count > 1): the session-handle binding (SetCurrentAttemptHandleForSession) is still keyed by sessionID alone, so two local seats in one attempt would collide. Member-keyed handles are deferred to PR2b-2; until then any multi-seat operator fails closed rather than mis-bind. Mirrors the coarse evidence path's multi-seat guard (submitSnapshotIfActive) in this same PR. Single-seat is unchanged. Tests: partial multi-seat (Codex's case) and fully-registered multi-seat both fail closed with a non-sentinel error and create no session binding.

That error flows through the tBTC executor into signingRetryLoop as a signingAttemptFn error, which the loop treats as a FAILED ATTEMPT: it drives transitionController.OnAttemptFailed, reportAttemptOutcome(false), and retries (`continue`). Because multi-seat is a STATIC condition no future attempt can resolve, the node would spin futile attempts until the signing timeout and synthesize garbage failed-attempt transitions, instead of failing closed (Codex re-review of #4085). Coarse fallback is not an option: interactive<->coarse mixing fractures the group. Fix (Codex+Gemini consult -> Option B, terminal error classification): - Add an exported ErrTerminalSigningFailure sentinel in pkg/frost/signing, documented as the THIRD disposition in the orchestration error taxonomy: STATIC -> coarse fallback; RUNTIME -> no fallback but RETRY (may be transient); TERMINAL -> ABORT the retry loop (static, futile to retry, unsafe to fall back). - BeginOrchestrationForSession wraps ErrTerminalSigningFailure for both multi-seat fail-closed branches (count>1, and the partial count==1 unregistered-seat case); count==0 stays the STATIC ErrNoRoastRetryCoordinatorRegistered fallback sentinel. - signingRetryLoop matches it via errors.Is and exits immediately (return nil, err) BEFORE the retry/transition machinery -- no OnAttemptFailed pollution, no spin. The loop only classifies retry disposition; FROST owns the terminal classification. Tests: orchestration fail-closed tests assert the terminal classification; a new signing_loop test proves a terminal attempt error aborts after exactly one attempt (no retry), while the existing RUNTIME signing-error case still retries. Verified: gofmt clean; builds green on default / frost_native / frost_roast_retry / frost_native+frost_roast_retry; pkg/frost/signing green across all 4 producer states + -race; full pkg/tbtc default suite green.

The local member (request.MemberIndex -- the receiver seat, never the inbound sender) is threaded through the receive-loop validators and the evidence-submission path; submitSnapshotIfActive becomes member-aware via RegisteredRoastRetryCoordinatorForMember. Retire the PR2b-1.5 multi-seat fail-closed guards that existed only because the binding was keyed by sessionID alone: the count>1 terminal guard in BeginOrchestrationForSession and the count>1 no-op in submitSnapshotIfActive. A fully-registered multi-seat operator now proceeds per-seat with isolated bindings. KEEP (do not retire) the partial-registration fail-closed: when THIS seat has no coordinator but a sibling is ROAST-active (count>0), Begin returns ErrTerminalSigningFailure, not the legacy-fallback sentinel. The ROAST-vs-legacy selector is process-uniform, so an unregistered sibling running legacy while siblings drive bound ROAST would fracture the attempt; member-keying the handle does nothing for a seat with no coordinator. Only count==0 (no seat registered anywhere) returns the static legacy sentinel. AttemptContext has no per-seat fields, so ctx.Hash() is identical across sibling seats: member-keying does not change validation semantics; it only isolates handles and prevents cross-seat cleanup. Verified across all 5 tag combos (default / frost_native / frost_roast_retry / both / +CGO frost_tbtc_signer) + -race + gofmt; pkg/tbtc signing-loop tests green.

Bridge the two: a member-keyed pending-evidence stash keyed by (RoastSessionID, member, attemptHash) -- the namespace-independent coordinate shared by the drive and observe worlds -- carries the raw recorder snapshot. submitSnapshotIfActive stashes it (dropping the dead drive-handle RecordEvidence); BroadcastForcedSnapshot consumes it and builds the ONE signed snapshot it broadcasts, so the elected coordinator's AggregateBundle includes the real evidence and computeNextAttempt can establish + exclude an f+1-accused member. Lifecycle mirrors the observe registry: consume on broadcast, clear on local success and session end, TTL sweep as a backstop; the Evidence is deep-copied on store. The stale selector comment is retired (the ROAST selector is already wired under frost_roast_retry). Design locked via Codex + Gemini consult (both PROCEED, no holes). Scoped to the coarse f+1 path; coordinator-equivocation proofs (interactive Round2Collector) are step 2b.

The OTHER exclusion path -- proof-carrying coordinator equivocation -- was still inert: verifiedCoordinatorEquivocations scans every bundle snapshot's CoordinatorPackageProofs and instant-excludes a coordinator that signed >=2 distinct authentic bodies, but nothing populated those proofs in the live path. The interactive runner's Round2Collector retains the coordinator-signed packages (and is NOT pruned on failure), yet they never reached the broadcast snapshot. Bridge it through the same pending-evidence stash 2a introduced, extended to a union {evidence, coordinatorProofs}: on an interactive runner failure, driveInteractiveRoastSigningIfEnabled surfaces collector.CoordinatorPackageProofs and stashes them by (RoastSessionID, member, attemptHash); BroadcastForcedSnapshot consumes them and passes them to the variadic NewLocalEvidenceSnapshot, so the seat's ONE signed snapshot carries them. Publishing the authoritative package on EVERY failed interactive attempt (not just locally-observed conflicts) is what lets NextAttempt aggregate bodies ACROSS observers and catch TARGETED equivocation -- a coordinator that sends different packages to different members, where no single observer sees both. Each writer upserts only its own field (coarse and interactive are mutually exclusive per attempt, but the union never assumes XOR and never drops the sibling's data). Proofs are deep-copied on store; lifecycle (consume-on-broadcast, clear-on-success, session-end, TTL) is unchanged. Stale "deferred cleanup stashes the transition bundle" comments retired (cleanup only clears the handle binding). Default-build no-op stub added for the frost_native drive path. Design locked via Codex + Gemini consult (both PROCEED, no holes). 2c (fault injection) follows. Prod-dormant until the cgo interactive engine is registered (gated on the frost-secp256k1-tr audit).

EngineRound2ShareVerifier and Round2Collector.ClassifyCandidate- Culprits were both complete but constructed/called nowhere -- so a member that submitted an invalid FROST signature share was never excluded and the retry could loop. Wire the third fault source on the interactive failure path (mirroring 2b): on a runner.Run share-verification failure, driveInteractiveRoastSigningIfEnabled type-asserts the engine to Round2ShareVerifyingEngine, converts the engine's uint16 candidates to MemberIndex (dropping 0 / out-of-range so a malformed candidate can never truncate into an honest seat), builds an EngineRound2ShareVerifier bound to the attempt, classifies each candidate's RETAINED share via ClassifyCandidateCulprits (frozen-Q1 boundary: only an ACCEPTED retained share that re-verifies INVALID is blamed; every not-the-member's- fault condition fails closed), and stashes the resulting reject accusations in the same union pending-evidence entry as the 2b proofs. BroadcastForcedSnapshot carries them; computeNextAttempt's f+1 reject gate excludes an f+1-corroborated bad-share member. f+1, not instant: a share is self-incriminating only against the package THIS observer accepted, so a byzantine coordinator's targeted split could otherwise make one honest observer instant-exclude an honest peer; f+1 corroboration (honest observers re-verify identical retained bytes deterministically) closes that. Best-effort + fail-safe: a non-share error, a verifier-incapable engine, malformed candidates, or an empty classification all stash nothing. Compile-time assertion that the cgo engine satisfies Round2ShareVerifyingEngine; the stale "evidence/proofs mutually exclusive" comments are corrected (one interactive failure now carries both). Design locked via Codex + Gemini consult (both PROCEED, no holes). Prod-dormant until the cgo interactive engine is registered (gated on the frost-secp256k1-tr audit).

Add a signed signer_ids field (member indices, ascending + distinct) to SigningPackageBody -- it rides the coordinator-signed body, so it is authenticated, not an unsigned sidecar. The SigningPackageBytes stays the cryptographic source of truth: the engine verifies shares against it, so a coordinator that lies in signer_ids causes only a LIVENESS failure (aggregate fails closed), never a wrong signature or false blame (Gemini's Option-B adjudication). Validate enforces structure (each a real member index so SignerIDs() cannot truncate; strictly ascending hence distinct); empty stays valid for the full-included flow, so this is fully back-compatible (the body-travels-verbatim discipline means old nodes still verify new packages over the received bytes). No behaviour change yet -- nothing sets or reads signer_ids. PR2 (runner subset) populates + consumes it; PR3 makes the done-check threshold-aware. The included-set oversizing that activates it is a deferred policy knob. Design locked via Codex + Gemini consult (both PROCEED).

Make the attempt finalize over the first t responsive committers instead: - Coordinator: collectCommitments now collects until EXACTLY t (the threshold) and stops, builds the FROST package over that t-subset, and carries the chosen members in the package's signed signer_ids (PR1's field), ascending+distinct. - Non-coordinator signer (in signer_ids): runs round 2 and collects round-2 shares from the package's signer set, not the full included set. - Observer (committed in round 1 but not in signer_ids): does NOT run round 2; it aggregates the subset's broadcast shares publicly, marks the attempt succeeded, and returns the signature - and still aborts the engine session on success to drop its unconsumed round-1 nonces (the success path previously suppressed the abort, which leaked an observer's nonces). t-of-included stays inert until participant selection oversizes the included set past the threshold (it currently trims to exactly honestThreshold), so the machinery is harmless and dormant until MacLane enables oversizing. PR3 will make signingDoneCheck (pkg/tbtc) threshold/package-set aware. Also harden the runner constructor to reject threshold > included-set size, the new round-1 collection loop's termination invariant. All behind the frost_native pre-prod build tags.

In a targeted coordinator-equivocation case where that member was handed a different package and broadcasts a divergent share, the collector is designed to keep it as EquivocationKindDivergentShare evidence for the f+1 blame/transition path - and the signer-set filter was discarding it. Split the membership gate: retain (hand to RecordShareSubmission) any INCLUDED member's well-formed share, but only COUNT signer-set shares toward the aggregate. The collector already enforces included-membership and keeps divergent shares separately; the runner now caches the included set (includedMembers) and gates retention by it, restoring the pre-subset evidence surface while keeping t-of-included counting. Added TestInteractiveSigningRunner_RetainsObserverDivergentShareAsEvidence: an included observer's divergent share is retained (EquivocationKindDivergentShare emitted) but not counted.

From 0671d99a3c855e201075da90cc5ca61a06c1a321 Mon Sep 17 00:00:00 2001 From: maclane Date: Fri, 19 Jun 2026 17:30:53 -0400 Subject: [PATCH 317/403] feat(frost): conclude the oversized signing done check by signature quorum (7.3 t-of-included PR3/3) Under RFC-21 Phase 7.3 t-of-included finalize, an interactive signing attempt is signed by the first t responsive committers of an (optionally) oversized included set; the non-subset and offline members never broadcast a signing done check, so the outer signingDoneCheck - which required a confirmation from EVERY attempt member - would hang an otherwise-successful attempt to its timeout and force a needless retry. Conclude the done check on a deterministic threshold quorum instead, keeping the legacy (non-oversized) path byte-for-byte unchanged: - non-oversized (included == honestThreshold; today's selector output and the whole coarse path): the legacy all-members rule is UNCHANGED - wait for every attempt member, require all signatures equal, return max(endBlock). - oversized (included > honestThreshold): bucket done checks by signature and conclude once a bucket holds >= honestThreshold distinct senders (the minimum that proves a valid threshold signature). Minority buckets (divergent or adversarial signatures) are IGNORED, never fatal, so one bad done message cannot fracture the group. The end block is the DETERMINISTIC attempt timeout block, not a network-order-dependent max over done messages. The deterministic end block is the crux: batch scheduling derives the next signature's start as signingStartBlock = prev endBlock + interlude, so a per-node max over a network-order-dependent subset would desync the batch. Returning attemptTimeoutBlock (which every honest node computes identically) fixes it. With honest majority (t > groupSize/2) at most one signature bucket can reach t - even under coordinator equivocation - so the quorum is unique and no body-hash / proto change is needed; the >1-quorum branch is unreachable and intentionally non-fatal. Design locked via a Codex+Gemini consult after the initial first-t-arrivals approach was shown to be cross-node non-deterministic (it fed an order-dependent end block into batch scheduling). Tests: legacy done-check tests unchanged; added oversized conclude-on-quorum (with a deterministic end block), minority-divergent-ignored, and split-below-quorum-times-out.

It exercises wire serialization of every RunnerMessage type (commitments, signing package, shares), the claimed-seat<->authenticated-operator-key binding, the per-type demux, and bounded delivery, with two cases: - full-included (group size == threshold == 2, every seat signs); - t-of-included (group size 3, threshold 2): the coordinator finalizes over a t-subset and the remaining committed seat observes, so the RFC-21 Phase 7.3 subset/observer flow is validated across the real transport too. This is the explicit prerequisite for retiring the coarse path ("real transport passes multi-node testing"). Test-only, frost_native (pre-prod) tag; no production behavior change. The standard client-* CI does not build frost_native tags, so this is validated locally (default + frost_native + -race).

Registering the cgo engine as the interactive provider made registerBuildTaggedNativeFROSTSigningEngine mutate a package-global provider, and that function runs from the default FFI registration path. Several tests trigger that path, so TestRegisterInteractiveSigningEngineProvider - which asserted "no provider yet" up front - failed under -shuffle / a focused -run when one of them ran first (reproduced: it saw a leaked *buildTaggedTBTCSignerEngine). Codex suggested resetting the provider in the default-registration cleanup; that alone is insufficient (verified: another default-registration test leaks it under a different interleaving). The robust fix is for the asserting test to establish its own precondition: it now resets the interactive provider up front, so it is order-independent regardless of which tests ran before it. Also reset it in TestRegisterNativeExecutionFFISigningPrimitiveForBuild_UsesDefaultProvider's cleanup (symmetric with its existing FFI executor/provider resets), so the test that mutates the global also tidies it. Verified: 10 -shuffle seeds of the cgo Register/Interactive tests pass (was an order-dependent FAIL before); the original repro order passes; non-cgo frost_native unaffected; cgo build/vet + gofmt clean.

It fills the gap in real-cgo coverage: - _WithLinkedSigner proves the real crypto over the LOW-LEVEL Sign/Aggregate API (fed KeyPackage bytes directly); - the fake-engine runner suite proves the Go-side orchestration without crypto. This is the missing combination - the interactive session API the runner uses, with real crypto - the prerequisite toward coarse-path retirement. THE keyGroup GLUE = RunDKG. InteractiveSessionOpen resolves the signing key by a keyGroup IDENTIFIER (engine-internal persisted material), not KeyPackage bytes, so the low-level DKG result the test holds as bytes is not loadable as an interactive keyGroup. RunDKG runs the full DKG, persists the result, and returns the keyGroup the interactive (and coarse) signing path resolves - the same flow production uses (the wallet runs DKG, gets a keyGroup, then signs). Correctness is proven by the engine's SUCCESSFUL InteractiveAggregate: FROST validates the shares and the aggregate internally, so a non-error 64-byte BIP-340 signature is a valid threshold signature over the message under the keyGroup's group key. The one remaining nicety, an ADDITIONAL external schnorr.Verify, is intentionally omitted: the engine exposes no keyGroup -> group-pubkey accessor (RunDKG returns only the keyGroup id), so external verification would need a new engine API. The e2e itself is complete via the internal validation.

RunDKG persists the DKG result in the signer's encrypted state, so a LINKED signer environment needs a state encryption key and an isolated state path - which the existing _WithLinkedSigner test did not need because its low-level Part1/2/3 DKG does not persist. Without them this e2e fails before signing (TBTC_SIGNER_STATE_ENCRYPTION_KEY_HEX missing), and a shared/default state path plus the fixed session id makes reruns conflict. Set both before RunDKG: a deterministic 32-byte test encryption key, and a fresh TBTC_SIGNER_STATE_PATH under t.TempDir() so each run starts from clean state. This makes the test self-contained in a linked environment (no external state setup, rerunnable). Still skips cleanly when the FFI symbols are absent. Verified: cgo build/vet + gofmt clean; the test still runs and SKIPS cleanly without the Rust lib.

Generalize the skip guard: skipFrostUnavailable turns ErrNativeCryptographyUnavailable from ANY engine call into a SKIP that names the operation and says to rebuild the lib, while any other error stays a real failure. Now the e2e is inert when the lib is absent OR incomplete, and runs to completion only against a current lib. Also document the link-and-run invocation in the file header. Verified: cgo build/vet + gofmt clean; skips without the lib (at RunDKG) and, against the stale lib, skips cleanly at the derive step (was failing) naming the missing symbol.

Findings that shaped the test: - The keyGroup glue (RunDKG -> keyGroup -> InteractiveSessionOpen) and the state isolation WORK against real crypto - RunDKG, DeriveInteractiveAttemptContext, InteractiveSessionOpen, and InteractiveRound1 all execute and produce a real commitment. - The engine requires threshold >= 2 (RunDKG rejects t=1) AND holds ONE open interactive member per session in a PROCESS-GLOBAL state (Open is fingerprinted once per session; interactive_state_for_attempt_mut rejects any non-opener member). By design each production node is its own process. So a single test process can faithfully drive exactly one signer's contribution, but NOT the full t-of-n finalize (package over t commitments -> round 2 per member -> aggregate), which needs the other members' contributions from their own processes. So this test now validates what one process can: a full real DKG that persists a keyGroup, then the local signer's interactive open + round 1 with real crypto - the real interactive path the runner uses, exercised end to end through the Go<->Rust FFI. The multi-member orchestration (t-subset across nodes, observers, real transport) is covered with the fake engine in the runner net e2e; a complete multi-member real-crypto signature is the remaining piece and needs a multi-process harness. Renamed _EndToEnd -> _MemberContribution to match what it asserts. Verified: PASSES against the linked lib; SKIPS without it; cgo vet + gofmt clean.

Adds a default-OFF KEEP_CORE_FROST_INTERACTIVE_SIGNING_ONLY gate; when set, the executor REFUSES to fall through to the coarse signing primitive: if interactive signing did not run (its audit gate off, or no engine), the attempt fails CLOSED rather than silently signing over the retired coarse path. The hard-fail on a committed interactive failure is unchanged; this only converts the (nil signature, nil error) "interactive not enabled -> coarse" fall-through into a refusal. Default off, so production is unchanged: coarse stays the path until an operator flips this on. Flipping it on IS the tECDSA->FROST cutover for that node (the coarse fallback is gone), so it stays off until the frost-secp256k1-tr external audit clears and the recovery-leaf decision lands - the actual code deletion of the transitional coarse primitive is the irreversible follow-up, deliberately deferred. Tests: TestEntry_InteractiveOnly_RefusesCoarseFallback (orchestration active + interactive audit gate off + this flag on -> the executor returns a refusal naming the env var, no signature) and TestEntry_InteractiveSigningOnlyEnabled_ParsesFlag. Existing static-fallback executor tests unchanged (the flag defaults off). Builds clean across the tag combos; cgo vet + gofmt clean.

KEEP_CORE_FROST_INTERACTIVE_SIGNING_ONLY was bypassed on exactly the misconfigured/cutover paths it was meant to protect. Move the enforcement to native_ffi_executor_adapter, the SINGLE point where the coarse primitive is invoked: when the orchestration yields no interactive signature for ANY reason (audit gate off, no engine, or any static fallback) and interactive-only mode is on, the adapter fails CLOSED before nefea.primitive.Sign instead of falling through. Revert the partial executor-entry check. Test moves to the adapter level: TestNativeExecutionFFIExecutorAdapter_Execute_ InteractiveOnlyRefusesCoarse runs in the DEFAULT build, where the orchestration helper is a no-op (nil,nil,nil) - the ultimate static fallback - and asserts the adapter returns a refusal AND the coarse primitive's signCalls == 0 (never invoked). Plus the flag-parsing test. Builds across all tag combos; existing adapter + executor-entry tests unchanged; gofmt clean.

Wrap the refusal with %w ErrTerminalSigningFailure; the adapter test now asserts errors.Is. Also folds my own review's scope notes into the gate doc: interactive-only is format-agnostic (refuses coarse for every signer format the native executor handles), closes both the inner FFI primitive and the outer fallbacks, and fails all native signing closed in a build without the interactive engine - so enable it only on a frost_native node with the audit gate on.

Neither exercises the real-engine <-> real-pkg/net-transport <-> runner seam together. This does: n interactive signing runners, each over its own real pkg/net BroadcastChannel bus, driving the real cgo engine to a real BIP-340 signature, in one process (full-included 2-of-2 and t-of-included 3/threshold-2 subset). Key wiring discovery (no engine change needed): the Go RFC-21 coordinator election seeds on SHA256(dkgGroupPublicKey || sessionID || messageDigest), and the Rust engine seeds the same shuffle on SHA256(keyGroup || sessionID || messageDigest) where keyGroup is the DKG handle string. Passing []byte(keyGroup) as the binding's dkgGroupPublicKey makes the two independent derivations agree, so the runner's engine-vs-binding coordinator cross-check (never before exercised against the real engine) passes. RunDKG persists a resolvable key group, so there is no loadInteractiveKeyGroup gap on this path. Shape (A) shares ONE process-global engine across all seats (ENGINE_STATE is a process-global OnceLock; the multi-seat fix #4098 is what lets one engine serve every local member). The seam surfaced a real, correct boundary: the engine's aggregate completion marker is per-ATTEMPT (attempt_id, message, root), not per-member, so the first seat to aggregate produces the signature and co-resident seats observe interactive_attempt_already_aggregated. That is faithful — in production each node has its own engine — and every seat still drives its FULL transport (commitments + shares broadcast/collected over real pkg/net) before aggregate. Assertion: exactly one seat aggregates a real 64-byte signature and reaches Succeeded; every other seat reached aggregate and hit the per-attempt idempotency marker (no other failure). Skip-guarded (absent/stale libfrost_tbtc skips at the up-front DKG). Verified vs the rebuilt lib: both tests pass, -race -count=3 clean (exactly one winner, no races), skip without the lib, cgo vet + gofmt clean.

CI builds NONE of the frost_native/frost_tbtc_signer/cgo tags, so the real-crypto interactive tests (incl. the multi-node e2e in this PR) are validated locally only and can silently rot. Adds .github/workflows/frost-cgo-integration.yml: it checks out the Go branch, checks out a PINNED mirror commit (ci/frost-signer-pin.env - an explicit SHA, not the moving tip, so an engine/bridge drift fails CI loudly in one reviewed unit instead of silently turning the real-crypto tests into skips), builds libfrost_tbtc, verifies the exported frost_tbtc_* ABI symbols, and runs the cgo-tagged tests with skips FORBIDDEN. The require-cgo gate is KEEP_CORE_FROST_REQUIRE_CGO=true, which flips skipFrostUnavailable's lib-unavailable SKIP to a FATAL - so an absent/stale/unloadable lib fails the job rather than quietly dropping coverage. Linker note (Codex): -Wl,--no-as-needed retains the DT_NEEDED on the lib even though the bridge references it only via dlsym(RTLD_DEFAULT). The Go interactive code and the signer crate live on separate branches today, so the gate checks the pinned mirror commit out into a side path and builds from there; after the branches merge, swap the cross-branch checkout for an in-tree cargo build and keep the gate. Locally validated: require-mode FAILS without the lib (was a skip), SKIPS when unset, PASSES with the lib; the workflow YAML parses (7 steps); the verified ABI symbols are present in the built lib. A CI workflow can only be fully exercised by running it on a PR. Production binary packaging + a structured ABI-version assertion are deliberately left as follow-ups (release pipeline / mirror), noted in the handoff.

Adds process-wide cumulative counters following the roast_retry_metrics.go pattern: - frost_interactive_signing_success_total / _failure_total: whether the interactive path, once driven, produces signatures or fails on a committed attempt. Emitted at the single executor-entry chokepoint where the drive's (signature, error) outcome is interpreted (the inactive fall-through - both nil - counts as neither). - frost_interactive_signing_coarse_fallback_refused_total: the FLIP-SAFETY signal - increments whenever no-coarse-fallback mode (KEEP_CORE_FROST_INTERACTIVE_SIGNING_ONLY) terminally refuses a would-be coarse/legacy signing, at all three #4101 refusal sites (legacy backend, native backend promotion, FFI adapter). During a staged flip a misconfigured node - interactive-only on but interactive signing not running - shows up here instead of silently failing every attempt. RegisterInteractiveSigningMetrics mirrors RegisterRoastRetryMetrics; operators wire it at startup (alongside the existing one, when the registration wiring lands). Emitted in every build, stays at zero until the gated interactive path runs - inert by default. This is the one genuinely buildable, non-gated item from the handoff's §6 production- integration review: §6.1 (signer material) is mostly already built (DKG+persistence; resolver fail-closed is tested), §6.2 activation wiring + §6.4 wallet lifecycle are gated, and the rest of §6.3 is ops/runbooks. Builds across all tag combos; new tests pass (incl. an end-to-end legacy-backend refusal bumping the counter); no regression; cgo vet + gofmt clean.

The bridge and the lib are linked at runtime via dlsym; a symbol that resolves but changed MEANING is silent corruption. This adds a fail-closed preflight that asserts the linked lib's FFI contract version before any contract-sensitive call. - Pure, fully-unit-tested rule (native_tbtc_signer_abi_version.go, untagged): lib abi_major must EQUAL requiredTBTCSignerABIMajor (1) and abi_minor must be >= requiredTBTCSignerABIMinMinor (0). Default-build tests cover every branch (wrong major either direction, too-old minor, higher-minor-additive-ok) via a parameterized helper. - cgo preflight (native_tbtc_signer_abi_version_frost_native.go): fetches the version via the new frost_tbtc_abi_version FFI, runs ONCE per process (sync.Once - the lib is process-global, not hot-swapped) before the first engine op. MISSING symbol keeps ErrNativeCryptographyUnavailable in the chain (explicit message; lib predates ABI versioning) so it SKIPS in dev and is FATAL under the require-cgo gate like any stale lib; PRESENT-but-wrong (malformed/wrong-major/too-old-minor) is ErrTBTCSignerABIIncompatible and fails loudly ALWAYS. - Gate: callBuildTaggedTBTCSignerOperation (the single chokepoint every request-taking engine op funnels through) runs the preflight first. The no-arg version/abi-version calls bypass it, so no recursion. - Bumps ci/frost-signer-pin.env to the mirror commit that adds frost_tbtc_abi_version (25e4f277a), and adds that symbol to the CI gate's verified set, so the gate builds a lib whose ABI the preflight accepts. Design via Codex consult (major.minor; exact major + min minor; init-time fail-closed; explicit missing-symbol error; no upper bound; frozen {abi_major,abi_minor} surface). Builds across tag combos; untagged rule tests + cgo preflight test pass; require-cgo full run green against the ABI lib; no-lib skips; default suite unchanged; vet + gofmt clean.

So an incompatible lib was NOT actually failing closed end to end: the ABI error got swallowed into a legacy signature. Fix at the single chokepoint - the top of signWithTBTCSignerCoarseEngine, before any fallback: a guard that fails closed on ErrTBTCSignerABIIncompatible (a PRESENT-but-wrong lib). A MISSING/absent lib is ErrNativeCryptographyUnavailable, NOT this sentinel, and still falls back to legacy as the transitional design intends - only a responding-but- incompatible lib is refused. The check is a build-split helper (tbtcSignerABIIncompatibility: real cgo preflight when linked, no-op otherwise), indirected through a var (tbtcSignerABIIncompatibilityCheck) so the no-fallback behavior is testable in the frost_native build. New test (mirrors _InvalidAttemptPolicy_DoesNotFallback): injects an incompatible ABI verdict + a valid attempt + a legacy-key-share payload, asserts Sign returns ErrTBTCSignerABIIncompatible, no signature, and ZERO fallback events. Bumps the signer pin to the mirror tip (6e3718ba0, which also adds the header decl). Builds across all tag combos; new test passes; existing fallback tests unchanged; cgo vet + gofmt clean.

A broken/partial lib could thus bypass the fail-closed guard.

Malformed JSON is rejected too; extra/unknown fields are still tolerated (an additive minor bump may add fields old bridges ignore). The cgo assertTBTCSignerABICompatible now calls it instead of a lenient inline Unmarshal. Tests: parser accepts valid (incl. present zero minor) + extra fields; rejects missing abi_minor, missing abi_major, empty object, malformed json, non-object.

A length >= 2^31 would overflow to a negative value and panic ("length out of range") at the cgo boundary, or silently truncate to a wrong length; reject it (the buffer is still released by the deferred free). - the request-call helper: scrub the secret request bytes from the C heap (the C.CBytes copy) before C.free. The request can carry signing-share / nonce material, and plain C.free does not overwrite; this mirrors the existing Go-side zeroBytes hygiene applied to the caller's own copy. - nativeExecutionFFIExecutorAdapter.Execute: recover panics raised along the cgo signing path and surface them as a failed attempt, so a single malformed native-signer response cannot take down the signing process. Adds a unit test with a panicking primitive (verified to crash the process without the recover). The cgo paths are compile-verified under -tags 'frost_native frost_tbtc_signer cgo'; the recover is exercised by an untagged unit test. The two cgo-tagged changes still need a runtime pass in the cgo + linked-libfrost_tbtc environment.

Silence-parking has no accuser-quorum gate, so a single transient mass-silence event -- or one byzantine member that is the elected coordinator for one attempt and omits snapshots -- could drop the IncludedSet below threshold and permanently kill a signing session, even though the original signer set could still complete it. This contradicts the file's own step-4 contract ("silence parking is strictly transient; a falsely-silenced honest peer recovers without intervention") and ErrAttemptInfeasible's own doc ("the session can no longer make progress with the original signer set"), and it routes a permanent failure around the very accuser-quorum defense that exists to stop a byzantine minority from grinding the group to ErrAttemptInfeasible. Evaluate feasibility against the permanently-available set (original \\ ExcludedSet): only permanent exclusions (established reject/conflict/ equivocation) can render a session infeasible. The next attempt's IncludedSet is still feasible \\ parkSet (it may fall below threshold for one attempt; the parked members are reinstated next attempt). When parking would empty the IncludedSet, reinstate the parked members rather than producing an unconstructable empty attempt. Pathological grinding under sustained malicious silence stays bounded by the outer tBTC signingAttemptsLimit. The two existing tests asserted the buggy behavior (silence below threshold -> permanent fail); retarget them to genuine permanent-exclusion infeasibility and add transient-silence-recovers coverage (single-step, full harness, and a two-attempt park-then-reinstate cycle).

The substitution LOGIC (observational logging, divergence rejection, matching-IO acceptance) remains covered directly by the TestEvaluateNativeUnsignedTransactionForSigning_* tests. Replace the four legacy-P2PKH substitution-through-signTransaction integration tests (which asserted the now-removed behaviour) with two gate tests -- SkipsNativeBuildForLegacyTransaction and InvokesNativeBuildForTaprootTransaction -- and retarget the two native-build error-propagation tests to a Taproot transaction (the only path on which the native build now runs).

A fix applied to one and not the other would silently make ECDSA and FROST select different qualified-operator sets for the same seed. This selection is structurally shared across schemes: it is the scheme-agnostic "pick the base signing group from the ready members" used for the initial attempt of every signing (and for DKG). FROST's per-attempt robustness diverges only on retries, via ROAST (NextAttempt); the initial selection does not -- ROAST is a transition-from-previous function and cannot produce attempt 0, so the initial selection is permanently shared. Move the algorithm (byte-for-byte, verified identical) into a neutral package, pkg/protocol/retry, and point both callers (pkg/tbtc/dkg_loop.go and signing_loop_legacy_selector.go -- the only two) at it. Delete pkg/tecdsa/retry and pkg/frost/retry. Keep the superset test (the tecdsa copy had an extra triplet-seat-count case the frost copy lacked). No behavior change; a single source eliminates the drift hazard.

(This is an authenticated-insider liveness halt the blame bridge does NOT close, because a never-observed attempt yields no evidence to attribute it.) markLostSync now uses CompareAndSwap and returns whether it transitioned, so the attribution is logged exactly once even while the listener keeps receiving such bundles. No change to the fail-closed semantics.

The seven sortition.Chain methods on TbtcChain switch on hasFrostAuthorization() (true whenever FROST is configured), and a single MonitorPool loop consumed them -- so the loop labeled "legacy ECDSA sortition pool monitoring" actually maintained the FROST pool during overlap, and post-cutover (DisableLegacyECDSA=true) the only loop stopped, leaving the FROST pool -- the one new FROST wallet DKG selects from -- unmonitored. Bind monitoring explicitly per pool. Two sortition.Chain views (ecdsaSortitionChain, frostSortitionChain) route directly to their own registry/pool with no hasFrostAuthorization() switch, and the node runs one MonitorPool loop per pool: - ECDSA loop: existing flags + policy, now correctly ECDSA-bound. - FROST loop: new DisableFrostSortitionPoolMonitoring flag (default-on), beta policy only (the ECDSA pre-params gate does not apply to FROST DKG), gated on FROST being configured and INDEPENDENT of DisableLegacyECDSA so the FROST pool stays monitored during the drain and after the legacy pool is retired. The operator is not necessarily registered in both pools, so the FROST loop treats sortition.ErrOperatorUnknown (now exported) as non-fatal: it warns and leaves FROST monitoring inactive rather than aborting node startup. The legacy loop keeps its existing fail-fast (the operator is ECDSA-registered during the drain). TbtcChain's own sortition.Chain methods are left unchanged, so heartbeat and other callers are unaffected; GetOperatorID stays ECDSA-bound. Both loops' join/update txs already share tc.transactionMutex + tc.nonceManager, so they cannot race on the operator account nonce.

For a FROST wallet on a canonical Bridge, a transient call failure would silently yield the left-padded legacy ID, and callers use WalletChainData.WalletID to choose P2TR (FROST) vs P2WPKH (legacy) scripts, so it would build or search the wrong wallet script. The error type cannot reliably tell a legacy on-chain Bridge -- where the walletID eth_call returns a normal RPC/ABI error even with the current binding -- from a transient failure, so distinguishing by error is fragile and breaks legacy deployments (Codex P1 on the first revision of this PR). Route the fallback by SCHEME instead, using the wallet's ECDSA wallet ID (zero => FROST, non-zero => legacy ECDSA), which GetWallet already has: - Legacy ECDSA wallet: its canonical wallet ID equals the legacy derivation, so fall back on any accessor error (and it is the only option on a legacy Bridge lacking the accessor). - FROST wallet: requires the canonical ID; surface the error rather than return a wrong legacy ID. A FROST wallet only exists on a canonical-ID Bridge, so the error is genuinely transient. Extracted into resolveWalletID with TestResolveWalletID covering all four cases.

This closes that DKG<->Sign zeroization inconsistency. The DKG engine methods build a Go-heap request payload (JSON), hand a C copy to the Rust FFI via C.CBytes, and receive the response as a fresh Go slice via C.GoBytes. callBuildTaggedTBTCSignerOperation already scrubs and frees the C-heap request copy, and the Rust side frees the C response buffer, but the Go-side request/response slices were never wiped. Mirror the Sign path exactly by deferring zeroBytes on the secret-bearing Go buffers, so a mid-function or error return still wipes: - Part1: response (round-1 secret package / private polynomial coeffs). - Part2: request (round-1 secret package) and response (round-2 secret package + per-recipient round-2 secret shares). - Part3: request (round-2 secret package + received secret shares) and response (final key package / long-term signing share). - RunDKGWithSeed: request (DKG seed that deterministically reconstructs the group secret); its response is public metadata only. Public-only buffers are left untouched (RunDKG request/response, Part1 request). The defers run after the decoders evaluate the return value, and the decoders return freshly hex-decoded copies, so wiping the transport buffers never corrupts the returned secrets. cgo-safe: the Go slices are independent of the C copies, so zeroing them after the call returns neither races the C side nor risks a double-free.

So the entire ROAST retry state machine and ~30 `frost_native` unit tests never compiled or ran in CI, and `make build` (the release/Docker path) shipped the `!frost_roast_retry` no-op stubs. This closes that activation gap. - client.yml: add a `client-frost-roast-retry` job that builds the coordinator path with cgo disabled (`go build -tags "frost_roast_retry"` and `-tags "frost_native frost_roast_retry"` over `./...`) and runs the tagged unit tests under the three non-cgo tag sets that cover the whole matrix (`frost_native`, `frost_roast_retry`, `frost_native frost_roast_retry`) over ./pkg/frost/... and ./pkg/tbtc/... against the mock FFI (no Rust lib, no Docker). - frost-cgo-integration.yml: add `frost_roast_retry` to the real-crypto cgo tag set and drop the narrow `-run` filter so the whole tagged pkg/frost/signing suite runs against the linked libfrost_tbtc (skips still forbidden); the heavy multiproc e2e tests already ran and self-constrain their worker subprocesses with anchored `-test.run`, so dropping the outer filter only adds lighter tagged unit tests. Add a step that smoke-builds the activation artifact via `make build-frost`. - Makefile: add a `build-frost` target that produces the ROAST-retry activation binary (tags `frost_native frost_tbtc_signer frost_roast_retry`, cgo-linked to libfrost_tbtc with the same CGO_LDFLAGS as the cgo workflow). - frost-roast-retry-rollout.adoc: replace the false claim that CI already exercised the tag with an accurate description of the new coverage. Locally validated (system Go, cgo off): `go build -tags "frost_roast_retry" ./...` and `-tags "frost_native frost_roast_retry" ./...` compile clean; all three non-cgo tag sets pass on ./pkg/frost/... and ./pkg/tbtc/... The cgo-linked full build is deferred to CI (requires building the Rust libfrost_tbtc, which the cgo workflow does from the pinned signer source).

Under the gate the lib IS linked, so `StartSignRound` instead reached the real signer and its provenance gate, producing a different error. Probe the linked lib with `assertTBTCSignerABICompatible()` - the same check the ABI preflight uses, which keeps `ErrNativeCryptographyUnavailable` in the chain iff the lib is absent - and skip the fail-closed assertions with a reason when the lib is present. The registration-wiring assertions still run under both builds, and the linked-lib crypto path is covered by `TestBuildTaggedTBTCSignerInteractiveFROSTBridge_WithLinkedSigner` and the `TestRealCgoInteractiveSigning*` suite. No assertion was weakened and no production code was touched; this matches the skip-when-unavailable pattern already used by the neighbouring cgo tests. Validated locally by building libfrost_tbtc from the pinned signer mirror and running the whole tagged pkg/frost/signing suite with the lib linked and KEEP_CORE_FROST_REQUIRE_CGO=true: 402 pass, 1 skip (this test), 0 fail; the real-crypto DKG/multiproc e2e tests ran and passed. Without the lib linked the test still runs its fail-closed assertions and passes.

Previously the coordinator↔chain wiring and the real cgo DKG execution were covered separately (frost_dkg_coordinator_test.go with stub results; frost_dkg_execution_frost_native_test.go in isolation) and never in one flow. The DKG output is real: a thin recording wrapper delegates to the cgo engine and captures the x-only group key, which the test asserts equals the key submitted on-chain byte-for-byte (no injected/fake result can pass), is a valid secp256k1 point, and backs a registered wallet. The group is reduced to 3 seats held by one node because the cgo engine is a process-global OnceLock and its development dealer DKG holds all key packages in one engine (n>=2; the library rejects n==1). Gated frost_native && frost_tbtc_signer && cgo, so plain frost_native builds are unaffected.

The build-tagged tbtc-signer engine registers whether or not the lib is linked, so the prior availability check passed even with an absent/stale lib and the missing ABI only surfaced inside the coordinator goroutine's RunDKGWithSeed, making the test hang until the 90s deadline instead of skipping. Now exercise the once-per-process ABI preflight up front via a raw seeded RunDKGWithSeed and route the result through a helper mirroring the reference skipFrostUnavailable: ErrNativeCryptographyUnavailable SKIPS (or FATALs under KEEP_CORE_FROST_REQUIRE_CGO), any other error fails. The probe runs on the raw engine so it never pollutes the recording wrapper's captured key. P2: remove the recovery-goroutine race. initializeFrostDKGCoordinator also launches recoverFrostDKGCoordinatorState; if it observed AwaitingResult before the OnFrostDKGStarted subscription, it could drive the DKG via the waitForConfirmation=false bypass and the deduplicator would suppress the subscription path, passing the test without exercising the confirmation flow. The chain now signals when recovery has completed its initial IDLE scan (the first GetFrostDKGState reader), and the test waits for that signal before flipping to AwaitingResult+emitting - so only the subscription's block-confirmation path can run. A deterministic assertion (submit block >= emit block + dkgStartedConfirmationBlocks) proves the confirmation waitForBlockHeight path was exercised and guards against silent regression.

Native FROST wallets carry native signer material that the transitional legacy signing backend cannot process, so a node left on the default/legacy backend produces valid wallets via DKG but then fails every signing attempt (heartbeat, deposit sweep, redemption). DKG uses the native path directly, so wallet creation succeeds and masks the misconfiguration until the first signature. Fail fast at startup: when FROST DKG is enabled but the signing backend is legacy, return a clear error pointing at tbtc.frostSigningBackend (set it to "native" or "ffi"). The native backend handles both native FROST and legacy-ECDSA material, so it is always correct once FROST is enabled.

A FROST node on "native" with an unavailable native engine therefore passed the guard, then fell back to the legacy bridge and failed on native FROST signer material at signing time instead of startup. Add signing.NativeExecutionAvailable() (mirrors the strict-mode availability gate but is consultable in any mode) and require it in the guard in addition to the non-legacy backend check.

So currentNativeTBTCSignerEngine() != nil alone still let the FROST startup guard pass on a frost_native && frost_tbtc_signer && cgo build with an absent/incompatible library, and the node would start only to fail DKG/signing at runtime. nativeSignerEngineAvailable now also requires ensureTBTCSignerABICompatible() == nil - the same cached dlsym probe of frost_tbtc_abi_version the wrapper uses at operation time, which returns nil only for a present, ABI-compatible library. Split into build-tag variants: signer (engine registered AND ABI probe passes), no-signer frost_native (false), and non-frost_native (false).

The real engine's share verification and the f+1 reject-blame exclusion policy (next_attempt.go) were only ever exercised separately (the policy with fakes); this wires them together. roast_runner_real_cgo_invalid_share_exclusion_frost_native_test.go drives: attempt 1 - a selected signer submits a structurally valid but cryptographically WRONG round-2 share (corruptingRound2Engine mangles the engine's share output); the coordinator's REAL aggregate fails with a typed share-verification error that NAMES the culprit; NextAttempt - an ExclusionAccuserQuorum (f+1) reject quorum against the culprit PERMANENTLY excludes it (ExcludedSet, not a transient park); attempt 2 - the surviving subset aggregates a real BIP-340 signature without it. Companion to the dropout/transient-park test (retry #1): same deterministic {coordinator, target}-only attempt 1, but the invalid share yields exclusion rather than parking.

Now assert, before driving the retry: - the coordinator fails SPECIFICALLY at 'collect shares' (it built + broadcast the package, produced its own share, then starved on the target's) -- not a generic early error; - the target REACHED round 2 and produced the share it withheld. Only the target's OUTBOUND share is dropped, so it still receives the coordinator's share and aggregates locally off the shared engine; that local success (sigLen 64, deterministic across runs) is the proof it produced -- and the bus withheld -- a genuine round-2 share. A pre-round-2 failure now fails the test.

Both name the elected coordinator and bind the authoritative signing package, so both are accepted aggregation shares -- a second accepted-but-different signed body is member double-signing. An honest Round2Collector fed the coordinator's authoritative package and both shares flags the second as EquivocationKindShareConflict (ErrShareConflict) and the process-wide observer receives the culprit-naming evidence. Closes the gap where the collector's conflict detection was only ever exercised with synthetic submissions and fakes, never over a genuine engine-produced FROST share submitted through the real transport. Detection is deterministic: the test drives an independent honest collector with the exact on-wire envelopes the Byzantine seat broadcast, decoupling detection from the runner's collect-shares drain race. Asserts the fault was actually reached -- a real round-2 share was produced and broadcast, and the two envelopes are distinct, same-package-bound accepted shares (a genuine double-sign, not a divergent share).

Two authentic bodies signed by the coordinator's own operator key are unforgeable proof, so verifiedCoordinatorEquivocations bypasses the f+1 accuser gate and forces INSTANT PERMANENT exclusion of the coordinator (ExcludedSet, not a transient park) even when the two proofs are split across two honest observers. Unlike the existing policy-level test, which uses a SHA-256 fakeVerifier, this uses a REAL secp256k1 operator-key Signer/Verifier (local_v1), so both packages must genuinely authenticate under the same verifier the coordinator instance carries. A non-vacuous negative control -- one authentic package plus one whose real signature is corrupted (rejected by the real verifier) -- is only one distinct authentic body and does NOT exclude the coordinator, proving the verifier is genuinely cryptographic and the positive exclusion required two authentic distinct bodies. Every snapshot carries no reject/conflict/overflow evidence, pinning causation to the equivocation path rather than an f+1 tally.

Closes the gap where the overflow primitive (enqueueOrRecordOverflow) and the park policy (next_attempt.go) were only ever tested separately -- the primitive with synthetic recorder-count assertions, the policy with hand-authored OverflowEntry bundles. Here the evidence the policy parks on is the exact evidence the real primitive produced against a real full bounded channel. The flooder is itself a bundle sender, so silence-parking cannot account for the park -- only the overflow quorum can. Asserts the fault was actually reached (the channel rejected enqueues and the recorder recorded overflow), that the park is transient (a following attempt with no accusations reinstates the flooder), and that the f+1 quorum is genuinely enforced (a single accuser does not park).

The test first proves the divergence is real (a registered, ROAST-active node selects the full 5-member transition set while a would-be legacy node trims to the honest threshold), then proves the fail-closed guard collapses that divergence: the SAME node-B Select call that returned a concrete legacy set with the registry empty FAILS CLOSED once ROAST is active (a wiring partial-registration), and node A fails closed on its missing expected transition. Neither emits a NextAttempt set, so they cannot converge on divergent ones -- the network fails closed instead of splitting. Closes the gap where the fail-closed branches were only exercised in isolation with fakes; nothing proved the two configs would actually diverge and that the guard, not chance, suppresses the divergent legacy selection. The false->true RoastRetryActive flip on node B's identical call is the proof, and each fail-closed decision is repeated to show it is a deterministic per-seat function of registry state.

This is the first increment toward replacing the node's transitional trusted-dealer keygen (executeTBTCSignerFROSTDKG -> RunDKGWithSeed), which the Rust signer hard-disables under TBTC_SIGNER_PROFILE=production ("production requires distributed DKG wiring"). The DKG crypto already exists over the FFI; what was missing is the orchestration that routes round-1 (broadcast) and round-2 (per-recipient) packages between seats. - distributedDKGRunner.Run drives the three rounds over a DKGBus for one member: broadcast the round-1 package, collect peers'; Part2 -> route each round-2 package to its recipient, collect those addressed to us; Part3 -> local secret share + the agreed group key. Every secret stays local; only public round-1 packages and per-recipient round-2 packages cross the bus. - An in-process DKGBus drives the deterministic test. Round-2 packages carry secret-share material and are addressed but not yet encrypted; phase 1 encrypts them to the recipient's operator key (reusing pkg/tecdsa/dkg's ephemeral-ECDH envelope) and runs over the real wallet broadcast channel. The real-cgo test runs 3 seats concurrently over the bus and proves they agree on one group key while holding distinct shares, then verifies a real 2-of-3 threshold signature under the DKG group key -- proving the bus-orchestrated shares are a functional threshold key, not just distinct blobs. Part3 cryptographically verifies each round-2 package against its sender's round-1 commitment, so a passing run proves the routing is correct. Race-clean.

A shared transport can carry other groups' traffic; counting such a sender fills a slot that a real peer's package is then dropped from (sortedRound1Packages iterates only the member set), so the runner would finish collection early and call Part2/Part3 with incomplete packages. Gates both round-1 and round-2 collection on the new memberSet. (Thanks: Codex review, P2.) - Zero the round-1/round-2 SECRET packages and the received round-2 packages once consumed, matching the engine's zeroBytes hygiene for the copies handed to the Go caller; DKG secret-share material must not linger in the heap. - Reject duplicate participant identifiers at construction (they would collapse round-2 routing) and build the identifier<->member routing maps from the member set only, not the broader identifierByID. - Guard inProcessDKGBus.subscribers with a mutex (matching inProcessRunnerBus) and document that its blocking sends need a buffer above the per-stream volume. Adds no-cgo (frost_native) regression tests: a non-member arriving first must not short-circuit round-1 collection, and duplicate identifiers must fail closed.

This adds an ECIES envelope over the existing pkg/crypto/ephemeral ECDH: the sender derives a symmetric key from a ONE-TIME ephemeral private key and the recipient's static (operator) public key, encrypts the share, and carries the ephemeral public key with the ciphertext. Only the recipient recovers the same key (ECDH with its private key + the carried ephemeral public key) and opens the share; the sender's ephemeral private key is discarded, giving per-message forward secrecy on the sender side. The underlying box is authenticated, so a wrong recipient or a tampered envelope fails to open rather than yielding a wrong share. The envelope is generic over ephemeral keys; the orchestrator will supply each recipient's operator key (converted to an ephemeral public key) and seal/open round-2 payloads when the transport is wired (phase 1b).

collectRound2 OPENS the share sealed to us with our private key and reconstructs the package Part3 consumes. A share we cannot open (corrupt, tampered, or sealed to another member) is skipped, so a bad share fails into the retry path rather than corrupting the DKG. - The runner now takes each member's public key (to seal to) and this node's private key (to open with); the constructor fails closed on a missing sealing key. In production these are the members' operator keys. - operatorPublicKeyToEphemeral / operatorPrivateKeyToEphemeral convert secp256k1 operator keys to the ephemeral (btcec) keys the envelope uses, with a round-trip test proving the converted keypair still ECDH-matches for seal/open. Also documents the seal envelope's security boundary (confidentiality only - authenticity and anti-replay come from the sender-authenticated transport and Part3 verification) and adds a malformed-ephemeral-key test. The real-cgo 3-seat DKG now runs the FULL encrypted round-2 path: each seat seals its shares to recipients and opens its own, and the DKG still produces one group key with distinct shares and a verifying 2-of-3 threshold signature.

scrub the operator scalar (review) - Bind every DKG round message to its attempt session and reject messages carrying a different session. Retries for the same wallet seed share a broadcast channel; without this discriminator a stale round-1/round-2 message from a failed prior attempt (from a retained member) would pass the sender/recipient checks, fill that sender's slot in the retry, and mix packages across attempts in Part2/Part3. The constructor fails closed on an empty session. (Codex P2.) - Zero the temporary 32-byte scalar copy of the operator private key produced by operatorPrivateKeyToEphemeral; PrivKeyFromBytes copies it, so the raw copy can be scrubbed on return, matching the surrounding secret-hygiene. (Codex P3.) Adds no-cgo tests: real-member round-1 messages stamped with a prior-attempt session are ignored (retry isolation), and a round-2 share sealed to the wrong key is skipped into the timeout/retry path rather than accepted.

Mirrors the ROAST runner bus: it authenticates a message's CLAIMED sender against the message's authenticated operator public key (MembershipValidator.IsValidMembership) BEFORE delivering, and demuxes into bounded per-subscriber round-1/round-2 streams with non-blocking, deduped delivery so a slow or flooding peer never blocks an honest broadcaster. - dkgTransportMessage wire format: sender || recipient || session-length || session || payload, with the DKG round type carried by the pkg/net Type() string; round-2 confidentiality stays in the seal envelope, not the transport. - The subscriber gains the mu/seen dedup state the net bus needs; the in-process bus leaves it unused. Tested (no cgo) via a fake net.Message exercising the receive path: authenticated round-1/round-2 demuxed to the right streams, a spoofed seat and an outsider dropped, a multi-seat operator's seats both accepted, byte-identical retransmission deduped, and the wire marshal round-trips + rejects malformed input. Node wiring (swap RunDKGWithSeed -> orchestrator over this bus, flip the production gate) is phase 2.

So the orchestrator now LEARNS each member's round-2 sealing key from the operator public key on its round-1 broadcast (which precedes round 2), instead of taking a recipientKeys map at construction: - Every message carries the sender's SenderPublicKey; the net bus sets it to the key it AUTHENTICATED the sender against (not any claimed value). The runner stamps its own operator public key on its broadcasts so peers learn ours. - collectRound1 parses each accepted sender's key into recipientKeys; a sender whose key we cannot parse is skipped (we could not seal a round-2 share to it). - The round-2 send seals to the learned key; the constructor now takes the node's operator private key (to open) and marshaled public key (to stamp), and fails closed on an empty public key. This is the node model the pkg/tbtc wiring (phase 2b) needs: a multi-seat node will run one orchestrator per local seat over the wallet DKG channel, each learning peers' keys from round 1. The real-cgo 3-seat DKG now learns keys over the bus and still agrees on one group key with a verifying 2-of-3 threshold signature; adds a no-cgo test that an unparseable round-1 key is skipped.

assert the authenticated key (review) - Deliver an addressed round-2 message ONLY to its recipient's subscriber instead of to every subscriber. Round-2 is per-recipient (n*(n-1) messages group-wide), so fanning every one into every subscriber's stream overflowed the buffer for mainnet-sized groups (default GroupSize 100 -> ~9900 round-2 messages) and deliverNonBlocking dropped honest traffic, timing out the DKG. Filtering by recipient bounds a subscriber's round-2 volume to O(n) (the shares addressed to it), so the 1024 buffer covers the largest group. Subscribe now takes the seat's member index. (Codex P1.) - Assert the net bus sets a delivered message's SenderPublicKey to the AUTHENTICATED operator key (the linchpin of secure round-2 key learning), and that a round-2 addressed to another seat is not delivered here. Clarify that the runner's self-key stamp is dropped on the net bus and re-derived from auth (the trusted stamp path is in-process-test-only).

The goroutine now calls it instead of the dealer executeFrostDKG. - Tests: pin CanonicalFROSTIdentifier and cross-check it against the engine's own DeriveInteractiveAttemptContext derivation in the e2e (the identifier the persist op and signing path require). Needs the signer op (keep-core PR #4136). Builds no-cgo and cgo; the distributed DKG, persist->interactive-sign e2e, and pkg/tbtc execution tests stay green.

multi-node e2e (review) Two blocking correctness fixes on the distributed DKG wiring, plus the multi-node integration test over the real transport that exercises them. - [P1] The runner broadcasts FINAL compact member indexes as the transport sender, but executeDistributedFrostDKG passed the membership validator built over the ORIGINAL sortition-ordered operators. When readiness compacts the active set (e.g. original seats 2,4,5 -> final 1,2,3), the bus authenticated the shifted seats against the wrong operators and dropped their round messages, timing out the DKG. Build the validator over finalSigningGroup's final-ordered operators (finalOperators[i] is the operator for final member i+1). - [P2] The DKG bus installed its channel Recv handler in the constructor, before the orchestrator subscribed the local seats. A fast peer's round-1 arriving in that window was handled with zero subscribers and dropped - and the transport's retransmission layer had already marked it seen, so it was never redelivered and the DKG stalled. Defer Recv into a new DKGBus.Start(), which RunDistributedDKGForSeats calls only after every seat has Subscribed. - Add a multi-node net-transport e2e: n nodes, each with its OWN operator key, run the distributed DKG over the real pkg/net broadcast channel via RunDistributedDKGForSeats (membership-authenticated, ECIES round-2 sealed to peers' learned operator keys), agree on one group key, and a threshold subset interactive-signs to a verifying BIP-340 signature. Reliable across -count=3.

Distributed material is signable ONLY via the interactive path; with it off, signing routes to the coarse path, cannot reconstruct a distributed key, and every signature fails closed. Gating the DKG on the signing opt-in prevents creating an unsignable wallet. (My review P2.) - Raise the required signer ABI minor to 1: this build calls frost_tbtc_persist_distributed_dkg_key_package (added in ABI 1.1), so a 1.0 lib now fails the ABI preflight and is FATAL under require-cgo, instead of failing later at the dlsym after the DKG already ran. (Codex P2.) - Replace the raw t.Skip in the distributed-DKG cgo tests with skipFrostUnavailable, which skips in dev but FAILS under KEEP_CORE_FROST_REQUIRE_CGO, so the cgo job cannot silently drop this coverage when the linked lib is absent/stale. (Codex P2.) - Correct the round-2 forward-secrecy comment: shares are ECIES-sealed to STATIC operator keys (sender-side forward secrecy only), NOT the two-sided per-DKG ephemeral exchange pkg/tecdsa/dkg runs. (My review P2, comment scope.) Builds no-cgo + cgo; the distributed-DKG, multi-node, and persist->sign cgo tests and the pkg/tbtc execution tests stay green.

Now each seat uses a FRESH per-DKG ephemeral key pair: - The orchestration generates one ephemeral key pair per local seat (no operator private key reaches the runner); the operator key stays with the channel, which authenticates each round-1 broadcast. - The seat's ephemeral PUBLIC key piggybacks on its already-authenticated round-1 broadcast (a new length-prefixed wire field). No extra exchange round is needed. Peers learn it, seal this seat's round-2 shares to it, and the seat opens them with the ephemeral private key, discarded when the DKG ends. - The net bus carries the ephemeral key on the wire (authenticated by the operator signature it validates the seat against) instead of overwriting it with the operator key. Both sender and recipient keys are ephemeral -> two-sided forward secrecy, matching pkg/tecdsa/dkg, but without the extra round. - RunDistributedDKGForSeats and executeDistributedFrostDKG drop the operator-key parameter accordingly. Adds a net-bus test that the delivered sealing key is the wire ephemeral (not the operator key) and extends the wire round-trip to cover the ephemeral field. The multi-node real-transport e2e still agrees on one group key and interactive-signs to a verifying BIP-340 signature (x3 reliable); all no-cgo and cgo distributed-DKG suites stay green.

The codebase already scrubs every other DKG secret (part1/part2 packages, round-2 shares) with zeroBytes; the ephemeral keys were the gap. - Add ephemeral.PrivateKey.Zero() (best-effort in-place scrub of the secret scalar's backing words; big.Int exposes no zeroization) + a test. - Scrub this seat's ephemeral private key when the DKG concludes (deferred in distributedDKGRunner.Run) and the one-time sender ephemeral after each seal (deferred in sealRound2Share). Both run AFTER their single use, so opening and sealing are unaffected - the multi-node and persist->sign e2es stay green. - Correct stale docstrings that still described the removed operator-key sealing path (RunDistributedDKGForSeats, openRound2Share, collectRound1) - the operator key no longer reaches sealing/opening.

The old pin (6e3718ba0) predates the ABI 1.1 bump, so the Go bridge - which now requires abi_minor >= 1 for the distributed-DKG persist op - fail-closed against it ("lib reports abi_minor 0, requires at least 1"), and every cgo-tagged real-crypto test failed. Bump the pin to 5a88e9a44 (feat/frost-distributed-dkg-persist head): ABI 1.1 with persist_distributed_dkg_key_package, the cross-session key_group resolution, the Round2 wallet-session gate re-check, and the emergency-rekey writer hardening. The old pin is an ancestor of the new one (clean forward bump), exactly the "bump this SHA in the same PR that requires a newer engine ABI" flow the pin documents. This unblocks the cross-session multi-node e2e that signs under a distinct session. (The separate client-integration-test failure is unrelated flaky infra - transient electrum test-server errors in pkg/bitcoin/electrum - and clears on re-run.)

A peer the barrier released ahead of a slower node can broadcast round-1 before that node is receiving; the transport drops it (no subscriber) and marks the pubsub sequence seen, suppressing retransmission, so collectRound1 times out and the DKG stalls (recovered only by a full retry). The earlier fix ordered only the LOCAL subscribe->Start->broadcast, not this cross-node window. Fix (register the receiver before the barrier): StartDKGMessagePrebuffer registers the DKG unmarshalers and starts capturing round messages off the channel BEFORE the readiness announcement. After the bus is Started and every seat Subscribed, RunDistributedDKGForSeats Replays the captured messages through handleMessage; the bus dedups by content hash, so any that also arrived live are ignored. Additive and low-risk - it only rescues messages that would otherwise be dropped; the happy path is unchanged (the in-process test bus's Replay is a no-op, and the multi-node test, which subscribes before Start, passes nil).

Replace Drain()+Replay() with DrainAndForward(sink): under one lock it snapshots and clears the buffer AND installs the sink as the destination for all further captures. The capture handler takes the same lock, so every message is EITHER in the snapshot (delivered to the sink) OR forwarded live to the sink - there is no handoff window in which a message is dropped. The orchestrator passes bus.Deliver as the sink (new single-message receive-path entry alongside Replay); the bus dedups by content hash, so duplicates are harmless. This also removes the post-drain retention nit (captures are forwarded, not accumulated). Test TestDKGMessagePrebuffer_DrainAndForwardHandsOff; multi-node e2e still green. Caught by review (Codex).
