Scope

Fail closed when acquisition evidence can manufacture buyer/data-room readiness through non-canonical time, invalid freshness configuration, coercible/out-of-domain commercial metrics, or coercible immutable-release asset metadata. Commercial thresholds and external evidence requirements are unchanged.

TDD lineage

  • bbc69eec...3c45bb79...: reject non-canonical/impossible updated_at evidence.
  • f2530a58...f8ad88be...: reject invalid timezone forms and future updated_at claims.
  • 653e31ce...d095ef43...: fail closed on invalid acquisition evidence max-age configuration.
  • 912ca902...b441219f...: require canonical typed revenue/customer/LOI and ratio metrics.
  • RED ea3d8d6c... → candidate lineage through current branch: immutable-release asset bytes must be a positive safe-integer JSON number, never a coercible string.
  • Non-destructive convergence 1d5c39f48b8b3244b3491c5c96267b7cbc21f32b: incorporate protected main d24ea29071412fa0cfebfbbde15a97405f1afa58 and its current immutable central-workflow trust binding without touching this PR's six acquisition paths.

Date-only YYYY-MM-DD and reviewed timezone-bearing timestamps remain supported. Licensing/IP gates, immutable release identity/digests, report-only semantics and foreign repositories are unchanged.

Current exact-head evidence

  • protected base: d24ea29071412fa0cfebfbbde15a97405f1afa58
  • exact head: 1d5c39f48b8b3244b3491c5c96267b7cbc21f32b
  • application CI 32503728934: queued
  • reviewer-ci 32503728919: queued
  • central Security Scan 32503728899: queued
  • Ready state is retained, but queued evidence is non-passing and predecessor results are not reused

Merge boundary

Do not merge until this unchanged exact head has terminal-success application CI, reviewer-ci and eligible central Security Scan, zero valid unresolved findings, and a fresh live-base/governance/scanner-authority recheck.

Merge Risk: ⚪ Minimal · up to 754dd

The PR tightens evidence validation while retaining supported date-only timestamps. The localized test-coverage follow-up does not indicate a production correctness or merge-blocking defect, so no actionable merge-blocking risk remains after normal checks and review.

📝 Info: Stricter updated_at parsing affects revenue and transfer gates

validateEvidenceMetadata now parses timestamps via parseIsoDateOrTimestamp, which rejects formats Date.parse accepted (no-timezone timestamps, space-separated dates). It gates both revenue and transfer evidence, so any producer emitting a non-canonical updated_at now fails closed. No in-repo files are affected.

📝 Info: metrics.pass cross-gates route fields

Both arrRoute and pipelineRoute now require metrics.pass, which validates every present metric. A present-but-invalid field unused by a route (e.g. an out-of-range gross_margin in pipeline evidence) now blocks that route where it was previously ignored. Absent fields are skipped, so only present-invalid values are affected.

📝 Info: Empty max-age env var now exits instead of using default

In parsePositiveNumber, an env var set to an empty string is now treated as explicitly invalid and exits with status 1, where the old code fell back to the default of 45. Ambiguous but fail-closed and consistent with intent.

📝 Info: Timestamp regex defers minute/second bounds to Date.parse

isoDateOrTimestampRegex validates hours strictly but accepts any \d{2} for minutes, seconds, and offset. Out-of-range values like 12:60:00 and +99:99 are rejected only because V8's strict ISO Date.parse returns NaN at acquisition-readiness-audit.mjs. Correct, but the rejection depends on Date.parse, not the regex.
