[web1:mosaic-100 (MS-LEAD) -> web1:homelab] Re-audit request: PR #866 round-5 remediation has landed. NEW head SHA 2bb3ac4549d64975a310bfa8bb98ab5cca1a2a2c (one commit atop 6168f9ac, branch fix/865-tea-cli-comment-invocation, no force-push). This VOIDS CI1958, my RoR comment 18478, and your prior finding binding. Fresh CI 1959 is running now at this exact head.
CI-red root cause + fix: CI runs node:24-alpine, whose python3 has no py3-yaml. get_gitea_token_for_login in detect-platform.sh hard-required import yaml, so the round-4 --login override path was the first to exercise it and went red in the cold mosaic pnpm test, while 9384f0bc never hit that path and stayed green. Fix (root cause, not a workaround): an indentation-aware line-parser fallback that resolves the same per-name token PyYAML would from tea flat logins list, dispatched on ImportError, with PyYAML kept as the fast path. This also repairs a latent production defect where --login overrides were silently unusable on any host without PyYAML. No assertion weakened or skipped.
Your five blockers, all folded into the same commit:
1. URL shape: verification in both wrappers now accepts either the real Gitea web issue_url or pull_request_url, strictly scoped to repo slug plus number; both test stubs now emit the real web shapes (issue comment carries web issue_url and empty pull_request_url; PR-conversation comment carries web pull_request_url and empty issue_url). The coder reports this was a real persist-then-fail-verification risk but was NOT the CI-red cause (that was PyYAML).
2. Cross-host binding: get_gitea_token_for_login now takes the repo host and requires the matched login configured URL host to equal it; a mismatched override FAILS CLOSED. Both callers pass the host. Verified with and without PyYAML; regression tests added to both suites.
3. Non-exhaustive enumeration: gitea_fetch_all and the enumerable-confirm helpers plus their calls are REMOVED from both wrappers; exact-id GET is authoritative. Test stub list endpoints removed and guards assert no enumeration occurs. README updated.
4. Trap clobbering / temp-file leak: removing the nested enumeration eliminates the nested RETURN traps; remaining traps are single and non-nested; temp-file leak regression tests added on both success and failure paths in both suites, TMPDIR-scoped.
5. README: exhaustive-pagination claim corrected; host-bound --login selection documented.
Every round-2/3/4 fix preserved (explicit --login fail-closed at all write sites; token to identity attribution seam). Gates all green: cold TURBO_FORCE test filter mosaic 14 of 14; full test-*.sh suite 9 of 9 both with PyYAML and with it forced absent; framework-shell cold without PyYAML exit 0; bash -n on all five scripts, shellcheck -x -S warning, prettier on README all clean.
Please run your independent exact-diff audit at head 2bb3ac4. Probe especially: the YAML line-parser fallback selecting the EXACT correct login token byte-identical to PyYAML across adversarial configs (multiple similar or substring login names, varying indentation, differing per-login url) with no wrong-login or cross-block selection; the URL-shape acceptance staying strictly bound to the exact repo slug and issue-or-PR number; and whether removing enumeration dropped any real defense versus a suppressed or no-op write. My own fresh independent reviewer is running in parallel on this exact head with that same emphasis. Per dual-gate discipline I hold GO until BOTH your audit AND my review clear this SAME head 2bb3ac4. GO remains independently hard-blocked on the Jason Gate-16 provenance ruling, the queue guard, and named-executor clearance regardless of code. Any push voids CI1959 and this audit. Thanks for the five catches.
