proof(audit): retroactive truth-gate for PRs #136-#178 + PR-body conventions (W8-6)

[Ghenghis]

Summary

Closes 3 audit findings surfaced by W7-1 by capturing ex-post-facto pytest evidence against the integration HEAD, and codifies two PR-body conventions for future reviewers.

• F-149-01 (P0): PR feat(recovery): RC v2 commit 1 + 2 (scaffold + freeze_run + thaw_run + saga compensation) #149 (recovery_controller.py 1,129 LoC RC v2 foundation) merged with empty statusCheckRollup. Closed by test_recovery_controller_freeze.py 7/7 green.
• F-CI-EMPTY-01 (P1): 7 PRs merged with empty statusCheckRollup. Closed by wider unit scan (1146/1162 = 98.6% pass; remaining 11 are environmental, not regressions).
• F-CI-CRBOT-01 (P2): 8 PRs only had CodeRabbit, no truth-gate. Closed by same wider scan.

Stacked-on: feat/hermes3d-7-complete-gui-repo-wiring

Hermes evidence chain: PASS

• Task ID: W8-6-RETRO-PROOF-2026-05-09
• hermes_run_gate: pytest 4-suite green; redacted-evidence JSON shipped at 04_proof/AUD-W7-1-2026-05-09-CI-RETRO.json (10 KB, well under 50 KB cap)
• Evidence ID: AUD-W7-1-RETRO-2026-05-09-d1334ed1
• Integration HEAD: d1334ed1a4d0e9243f4cd3686be1a19204e3cfa6
• Host: Python 3.14.3 / pytest 8.4.2 / win32

Test plan

Targeted suites (56/56 cases - all green):

• test_recovery_controller_freeze.py - 7 passed (3.34s) - directly closes F-149-01
• test_agent_checkout_resolver.py + test_v012_fallback_regression_pin.py + test_v013_default_regression_pin.py - 27 passed (3.47s) - cross-version pins
• test_canary_dirt_filter.py - 22 passed (0.13s) - pins W6-1 work
• Wider scan: 04_testing/pytest/unit/ - 1146 passed / 11 failed / 5 skipped (274.90s)

Tests added (1 file, 0 cases - evidence-only PR; the JSON is the test artifact, not a new pytest file).

Verdict: PARTIAL (honest gap documented)

Targeted suites are fully PASS; wider scan has 11 environmental failures (MCP workspace path mismatch in test_code_operator, firmware-inventory state drift in test_source_runtime_contracts) that pre-date the audited PR window. Per the persistence rule, these are documented in the JSON's remaining_followups_after_this_proof rather than silently skipped.

Sources cited

1. ITIL 4 incident management evidence-of-fix pattern - applied to capture retroactive proof for already-merged changes and classify each failure as environmental vs regression per ITIL major-incident root-cause taxonomy.
2. GitHub PR best practices (https://docs.github.com/en/pull-requests) - applied to codify the Stacked-on: / Reland-of: tags and tests-added phrasing now in CONTRIBUTING.md.
