RED: classify_decision_outcome labels every allow without an applied or errored obligation as obligation_skipped / obligation_executor, even when no obligation outcome exists (obligation_skipped_present=false in the same record). Expect a policy_allow / policy_engine outcome, a new decision_basis_version for newly emitted records, the wire enum parity to admit policy_allow, and retained wave39_v1 records read as stored.

…_allow classify_decision_outcome ignored obligation_skipped_present, so every allow without an applied or errored obligation became obligation_skipped / obligation_executor, including plain allows with no obligation at all. Real proxy captures showed it on every allow, next to obligation_skipped_present=false in the same record. Add DecisionOutcomeKind::PolicyAllow (origin PolicyEngine) for that case and keep ObligationSkipped for an actually skipped obligation. Mirror the variant in the incident decision wire enum, map it in the replay, deny and restrictiveness projections, and stamp new records with decision_basis_version wave39_v2 so replay does not compare a pre-fix and post-fix allow as identical. Retained wave39_v1 records are read as stored. Re-pin the reviewed producer-source digests. Breaking for the Rust API: DecisionOutcomeKind is not non_exhaustive. Decision: Grok 4.7 High and Muse (muse-wonder-1.0) both chose this as the next step and recommended this shape. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ON_V2 Drops the now-unused V1 import that clippy -D warnings rejected; the literal wave39_v2 stays pinned in replay_diff_contract. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Non-building review of head Verdict: BLOCKED. The classification claims hold. The block is the required semver job, which has already failed on this head. F1, open: semver job failed
Printed from that job log: Workspace Public API on this diff:
A major bump, or a recorded semver override, is what makes this head pass that gate. Nothing else in the diff needs to change for that. 1. Consumers of the new variantI looked for a missed match and did not find one that mishandles Searches: Exhaustive arms that name

… API break Review of the previous head: the enum in assay-evidence's decision_wire_v1 is private, so adding policy_allow widens incident admission without breaking that crate's public API. The assay-core break stays as stated. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The current-head failure is the consequence of the unchanged breaking enum and release configuration.

The checked-in goldencombined_session_3345.tar(awave39_v1record with outcomeobligation_applied) still reproduces byte-identically.

DecisionOutcomeKindis public and not#[non_exhaustive], so exhaustive matches outside the workspace must add an arm. This is semver-major forassay-core.
