fix(engine): route reflexive triggers through the stack - #7332
Conversation
Reflexive ("when you do") triggers from mana-ability costs and resolutions
now materialize as real deferred triggers released through the stack at
their owner boundary (payment, cast announcement, or resolution
settlement) with CR 603.3b APNAP batching, instead of a completed mana
frame self-releasing its own batch.
- A completed mana micro-frame queues its reflexive + observer trigger
contexts in `deferred_triggers` (durable, serde round-tripped state)
and returns to the owner prompt; only the owner boundary releases the
batch onto the stack.
- Nested parent mana topologies keep per-frame cost-event ledgers
disjoint; a suspended parent's retained prefix joins the batch via
parent-snapshot suffix augmentation.
- Targetless/nonmodal `ManaAdded` observers are classified as triggered
mana abilities and resolve inline inside the frame; optional and
opponent-may bodies pause and resume the frame on readiness.
- Delayed one-shot and whenever-event triggers matching TapsForMana join
the frame batch under the same ordering.
- `build_resolved_from_def` replaces four inline ResolvedAbility
literals in vote tally resolution.
- Eliminated players' queued contexts are cleaned up; the client
envelope never carries the sidecar or construction-recipient state.
Known gap, documented in the tests rather than encoded as a contract: a
rider-free unless-payment has no settled-Priority convergence yet, so
its queued batch is released only by the next owner boundary.

- Around line 2358-2362: Update reflexive-trigger materialization around
try_materialize_reflexive_trigger so modal abilities with a passing
QuantityCheck condition are handled before the target-slot fallback. Ensure
target-less modals do not return false and resolve all modes; instead preserve
the modal-choice path by producing WaitingFor::AbilityModeChoice, or enforce an
equivalent invariant for this shape. Keep the existing WhenYouDo handling
unchanged.
- Around line 2293-2296: Update build_target_slots to treat reflexive.targets as
complete for pre-bound reflexives whose condition is
AbilityCondition::WhenYouDo, so it returns no target-selection slots and
begin_pending_trigger_target_selection does not prompt again; preserve the
existing behavior for other reflexives.
- Around line 13158-13173: Strengthen the test
reflexive_with_no_legal_required_target_is_dropped_by_shared_dispatch by
capturing the boolean returned from try_materialize_reflexive_trigger, asserting
it indicates successful materialization, and verifying the deferred trigger
queue contains the trigger before drain_deferred_trigger_queue runs. Keep the
existing post-drain empty deferred_triggers and stack assertions to prove the
trigger is dropped during shared dispatch.

- Around line 9397-9404: Update the comment above the activate_mana_ability flow

Changes requested on a789202d99cf3bc5458ff4f13d849c84b2d7628d. The merge conflict itself is maintainer-side staleness (main's #7327 rewrote the same line-pinned census after this branch's base), so please do not spend time rebasing it. I will port that mechanical conflict after the substantive issues below are corrected.
Blockers
-
crates/engine/src/game/elimination.rs:254-258describes routing the carried construction-priority recipient in current turn order, but callsplayers::next_player. That helper is explicitly physical seat-forward;players::next_player_in_turn_orderis the established direction-aware authority and usesprevious_playerunderTurnDirection::Reversed. A reversed multiplayer game therefore sends priority to the wrong surviving player. Use the direction-aware helper and add a discriminating reversed-turn-order elimination regression where the departed carried recipient is not the construction prompt owner. -
crates/engine/src/types/game_state.rs:20708-20900normalizes the fields used by loop equality, whileGameState::PartialEqstill comparespending_triggered_mana_resumeat:21992. The newTriggeredManaResumecarries a monotonicrules_execution_nodeand nested trigger contexts (current,accepted_tail, andcollected_batches;:7460-7487), butnormalize_for_loopnever canonicalizes that sidecar. Equivalent paused triggered-mana loop states therefore compare unequal solely because their execution identities advanced, producing a false negative in loop detection. Normalize the node and recursively clear trigger identities across every sidecar context, with a regression that differs only in those volatile identities.
Cleanly separate from this review
The sole textual conflict against current main is the coordinate census in crates/engine/src/game/engine.rs; main commit 79e44116d58e2f0897df41f140007a6dd8efbbc6 (#7327) introduced its side and is not an ancestor of this PR head. That is maintainer work, not a contributor rebase request.
Recommendation: address the two behavioral blockers on a new head; maintainer will then port the mechanical #7327 conflict and re-review the resulting head.

Maintainer hold on current head The immediately preceding changes-requested review raced with this follow-up commit: its two reported behavioral defects are addressed by the current delta ( The remaining I am keeping the PR held while the full current-head implementation review and required Rust/frontend/parse-diff evidence are completed. If the current head clears those gates, the maintainer will port the single mechanical census conflict and re-review the post-port head; no contributor action is needed for the conflict itself. |
Dismissed because the author pushed ae8c1fe before submission; that commit addresses the two findings. The current-head maintainer hold states the remaining review and evidence gates.

Reflexive ("when you do") triggers arising from mana-ability costs and resolutions now materialize as real deferred triggers released through the stack at their owner boundary — payment, cast announcement, or resolution settlement — with CR 603.3b APNAP batching. Previously a completed mana micro-frame self-released its own ordering batch.
This is the sixth and final piece of the batch that produced #6997, #7007, #7008, #7017, and #7039.
What changes
deferred_triggers(durable, serde-round-tripped engine state) and returns to the owner prompt; only the owner boundary releases the batch onto the stack.ManaAddedobservers are classified as triggered mana abilities and resolve inline inside the frame (their mana is spendable by the very cast that masked the frame); optional and opponent-may bodies pause the frame and resume it on readiness, not on production.TapsForManajoin the frame batch under the same ordering.build_resolved_from_defreplaces four inlineResolvedAbilityliterals in vote tally resolution.client_state_wire_valuenever carries the sidecar or construction-recipient state to either root.Known gap (documented, not encoded)
A rider-free unless-payment has no settled-Priority convergence yet —
finish_successful_unless_paymentruns the pipeline only when it resolved a sub-ability — so a bare paid cost releases its queued batch only at the next owner boundary. The two tests that border this record it in doc comments rather than asserting the gap as a contract; closing it is therun_post_action_pipeline_from_settled_priorityfollow-up.Tests
