Defect A root cause: Gitea runs-list page flood (scheduled merge-robot
runs push relevant SHAs past the limit=50 first page) + collect-only-
first-page pagination -> terminal commit read as pending -> parked until
deadline. FIX: _fetch_runs paginates up to 4 pages collecting all matches
before verdict.
Defect B root cause: authority_verdict spawned deploy_qualify reading
DEPLOY_SHA from ambient env. FIX: explicit --sha arg (env masked when
sha is explicit); _ci_runs_verdict/op_ci_alive take sha as parameter
only; no env read remains in the authority path.
Defect C root cause: model sha treated as lookup key — a typo derived a
ghost operation. FIX: model sha is a HINT; unresolved sha + single
pending op -> stored target used with model_sha_mismatch logged; bound
op always wins over hints. deploy_qualify gained --sha flag (env kept
for workflow backward-compat only).
Tests: H-matrix (identity, prefix collision, env staleness,
monotonicity, aggregator lag, operation-id-first) + full 2179 suite.
The await_operation first-class tool (and any local deploy_qualify.py
caller) never exported GITEA_SERVER/GITEA_REPO, so main() printed
'pending' unconditionally — the first-class wait could never resolve
success even against a green, converged deployment. CI behavior is
unchanged (env always exported there); the fallback only fires when
the caller omitted the vars. Root-caused live in T21.4 G10 dogfood.
ROOT CAUSE (red-CI promotions 0.66.28/29): the required-checks
'Publish protected-branch gate' step read /tmp/need_* files that no step
ever wrote and echoed 'All required CI checks passed' UNCONDITIONALLY.
With if: always() the needs gate is overridden, so the job ran on red
needs and published success — deploy_qualify correctly trusted it and
promoted red commits (24413e4, fd6e9b4, de30cd9; status timelines in the
closure evidence).
FIX: publish step now runs only when every needs.*.result == 'success';
companion fail-closed step exits 1 otherwise, so the required-checks
context reports failure instead of lying.
DEFENSE-IN-DEPTH: deploy_qualify verdict is now the AND of two
independent legs — (1) newest required-checks observation for the exact
SHA, (2) the latest COMPLETED ci.yml@refs/heads/master run for that exact
SHA with every job concluded success (fan-out resolved by path, run
resolved by head_sha, jobs envelope unwrapped — no aggregate-status
fallback). Any pending/missing/disagreement = not deployable.
CANARY: gitea_pipeline now asserts the verdict evaluates needs results
and fails closed — the class locked shut. 20 qualifier tests with
fixtures from the real incident shapes; 1402 suite green.
The embedded multi-line python in the workflow run blocks terminated the
YAML literal scalars — Gitea could not parse deploy.yml at all (dispatch
500: 'could not find expected :'), which is why no deploy runs appeared.
Logic now lives in scripts/deploy_qualify.py + deploy_stage.py; the
workflow is pure shell + script calls.
