Purpose

Focused four-file Finisher observer/collector implementation. Captures an unsigned, fail-closed journey over eight agent fronts with exact owner readbacks, safe process cleanup, rollback restoration checks, documentation, and regression tests.

Dependency / base

• Stacked on draft Repair release checks, readiness deadlines, and dependency policy #25 — branch agent/certforge-readiness-20261003, pinned base SHA 424fc76fa09d9a83fcbe0d2ec12dc62ef97859c9.
• Repair release checks, readiness deadlines, and dependency policy #25 provides required production-E2E schema/entry points. Do not merge independently or before Repair release checks, readiness deadlines, and dependency policy #25 is integrated and revalidated.
• Replaces the contaminated original draft Finisher: independent fail-closed live verification collector (task 50135) #44, which remains unchanged; PR47 excludes all 16 unrelated inherited commits.

Exact source and scope

• Current head: 2e0d592b031c5482bf69f150aec74012dc953bf8.
• Git tree: 5efe62b70c08a911e2bf7ae9df3d766506215ca7 — bit-for-bit match to isolated QUENCH hardening commit f5a8fbabb2ee4c70b0934a99631b631e0809c74d.
• Four files relative to Repair release checks, readiness deadlines, and dependency policy #25:
  • docs/FINISHER_COLLECTOR.md
  • scripts/collect_finisher_e2e.py
  • src/echo_certification_forge/finisher_collector.py
  • tests/test_finisher_collector.py
• Fourth commit strengthens trust boundaries: 24 separate named owner-issued/recalled stability-front observations (three windows × eight fronts), exact route/provider/snapshot hash binding while permitting one shared Cloudflare singleton run ID, and exact comparison to four owner-approved immutable rollback checkpoint/config digest pins. Malformed/replayed/cross-front proofs fail closed.
• No generated P1 report, deployment asset, or unrelated file is part of the diff.

Checks (2026-11-08)

• Current hardening tree: QUENCH Windows Python 3.14 focused tests 74 passed, 6 skipped, exit 0; Python compile and whitespace check passed.
• Current hardening tree: P1 acceptance 3/3 scenarios passed, exit 0. Source-only and tampered evidence remain blocked; deploy gate denied and verdict NOT_READY.
• Previous pre-hardening tree only: QUENCH full pytest -q 760 passed, 9 skipped; FORGE Linux focused 65 passed. These results are historical and do not qualify the new head.
• Current head GitHub-hosted full CI, P1/P6/P7 acceptance and CodeQL: pending independent results. Local full suite was intentionally deferred due low QUENCH available RAM and bounded FORGE I/O stall, not represented as passing.

Release disposition: NOT_READY

No admitted Finisher-specific independent eight-front production attestation, source/artifact identity sign-off, rollback operational proof, or authorized independent signed release verdict exists for this PR. Keep DRAFT and prevent deployment/merge until hosted CI, CodeQL, independent security review, real owner admission, production E2E, and sign-off are complete. Do not substitute a fixture or simulated success for genuine evidence.
