drafts: true📝 WalkthroughWalkthroughThe event system increases history-collector mailbox capacity. Decryption-share and C6-proof generation now uses the canonical honest roster. Integration benchmarks validate fixtures, thread reservations, local aggregation, event boundaries, and correlated C6 verification events. ChangesCanonical decryption and benchmark validation
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The PR improves benchmark stability, but the current head can silently skip C6 verification when roster persistence fails, accept decryption shares from non-committee parties in tests, and fail on incomplete local fixtures instead of using the fallback. Merge should wait for these issues to be fixed or explicitly accepted. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Report failure to persist the canonical roster.
try_mutate errors are discarded. If persistence fails, this handler logs that it stored the roster and returns successfully. A later CiphertextOutputPublished then finds no roster and skips C6 work.
Report EType::KeyGeneration and return when this mutation fails.
Proposed fix

+ if let Err(err) = self.state.try_mutate(&ec, |mut s| {
s.aggregated_pk = Some(pk);
s.honest_parties = Some(honest_party_ids.clone());
s.decryption_domain = Some(e3_committee_hash::DecryptionDomainContext {
interfold_address: self.interfold_address,

committee_public_key: data.pk_commitment.into(),
});
Ok(s)
