Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR strengthens protection of canonical recorded-time and governance evidence, but two text validators still accept string subclasses instead of enforcing the stated exact built-in text contract, leaving a bounded non-canonical input path. The change is mergeable with explicit owner awareness and follow-up. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

@opencode-agent Please review the current unchanged head against protected |
_canonical_timestamp accepted any built-in timezone instance, so a low-level object.__setattr__ could reintroduce timezone(+09:00) and serialize +09:00 into canonical_json, changing the SHA-256 evidence digest. Require identity with the single timezone.utc instance instead. RED->GREEN regression: builtin fixed-offset (+09:00) reinjection now raises ValueError; suite stays at 100% statement/branch coverage (coderabbitai Major thread on PR #60).

Extend the exact-primitive boundary to _validate_digest and _validate_evidence_version_code so a str subclass carrying forged __eq__/__hash__ cannot validate as one value and serialize as another. Covered by parametrized forgery regressions; coverage stays at 100% statement/branch (devin Info thread on PR #60).

Live lifecycle correction — 2026-09-06
Live authority is now protected

This PR still carries exact feature head6417a590e97916782f600aee0c1f05220b42ff9don the older recorded base snapshot9e3e4847510e1e612b48474ba42b177b8ed824df; GitHub currently reports it Draft and non-mergeable. The earlier body statements saying non-Draft/mergeable and treating9e3e484...as the live protected truth are historical only.The valid Selection Review hardening delta is preserved. Do not close, force-rebase, or choose one side of the tree merely to remove conflicts. Before any Ready transition, non-force adopt the current protected
develop, reconcile semantic/provenance conflicts while retaining the feature regressions and protected #161 repository-quality consolidation, reseal any deterministic artifacts from final bytes, and reacquire every applicable exact-head local/central/security/review gate. Historical exact-head GREEN remains evidence for the old feature snapshot only and does not transfer across that reconciliation.Current governed repair
This Orgmetra-only lane hardens
SelectionReviewPacketcanonical recorded-time and trust-bearing text evidence without changing selection-decision authority. Construction accepts only exact built-in trust primitives, freezes valid recorded time to one immutable UTC instant, rejects caller-controlled timezone behavior and post-construction timezone reinjection, and keeps canonical JSON/SHA-256 deterministic. Timestamp overflow is normalized into the packageValueErrorcontract. Earlier findings about mutable/customtzinfo, built-in non-UTC reinjection, andstrsubclasses inevidence_set_digest/evidence_version_codewere repaired with regressions; addressed threads are resolved.No dedicated-writer dependency repository is modified.
Historical exact-head evidence
Feature head
6417a590e97916782f600aee0c1f05220b42ff9dpreviously had terminal GREEN Orgmetra-owned evidence for Selection Review Quality, Foundation CI, Recovery Rehearsal Quality, SAST/Semgrep, Requisition Review Quality, Job-Analysis API Quality, PostgreSQL/owned coverage controls, the PR review merge scheduler, close-empty-PR control, Code Quality, Dependency Review, Scorecard, Trivy and OSV against the olderdevelop@9e3e484...snapshot. That evidence is not current protected-parent acceptance.Required central review evidence on that historical snapshot remained fail-closed: OpenCode lacked a formal exact-head verdict, historical Noema timed out under an older trusted central source, and Strix published internally contradictory target/finding evidence. No qualifying independent current-head non-author
APPROVEDreview exists.Merge governance
This PR is not merge-ready. Keep Draft until protected-parent reconciliation is complete and the reconciled exact head satisfies every then-applicable Orgmetra and central required workflow, authoritative security evidence, resolved review conversations, and qualifying independent review requirements. Do not self-approve, use routine administrator bypass, transfer predecessor evidence, weaken a gate, manufacture evidence, add a no-op retrigger commit, race another lifecycle writer, or mutate a dedicated-writer dependency.
