fix(merge-control): harden ci-required-drift.py + gitea-merge-queue.py

(Kimi authored the branch + commit; agent-dev-b is opening the PR because Kimi's PR-creation token failed mid-session and the cross-agent assist was authorized via the activity_logs delegation channel. Branch is already pushed: fix/merge-control-script-hardening, head 114ee8c71535530229e29124c6b172156f45bff3.)

What this PR changes

.gitea/scripts/ci-required-drift.py

• Add fail-closed validation of REQUIRED_CHECKS_JSON array items: reject non-string, empty/whitespace, and duplicate contexts.
• Prevents malformed audit manifests from being silently normalized (hiding config errors).
• Add regression tests for non-string, empty, and duplicate cases.

.gitea/scripts/gitea-merge-queue.py

• Add enumerate_readiness(): evaluate ALL candidates and return their readiness states without stopping at the first actionable one.
• Add print_post_batch_summary(): structured operator visibility (counts + per-PR state/action/reason).
• Add --enumerate CLI flag for report-only batch evaluation.
• Fail-closed: API errors per candidate are recorded as unverifiable rather than skipped silently.
• Add tests for full-candidate evaluation, ineligible detection, and fail-closed API-error handling.

Why this matters

The merge-control surface is the owner-side gate that decides which PRs are mergeable (and surfaces the ones that aren't, with operator-readable reasons). Two specific failure modes this PR hardens against:

1. Silently-normalized malformed manifests (ci-required-drift): if REQUIRED_CHECKS_JSON contains a non-string or duplicate context, the script could normalize it away and emit a "clean drift" report. That's a silent gate-weakening — the same class of failure the #2392/#2398 fixes hardened on the other side. The new fail-closed validation rejects malformed entries outright.
2. First-actionable-only batch evaluation (gitea-merge-queue): the old behavior stopped at the first actionable candidate, which meant a single bad PR could mask the rest of the batch. The new enumerate_readiness() evaluates ALL candidates and print_post_batch_summary() surfaces the whole picture. API errors are recorded as unverifiable (not skipped) so a transient API hiccup doesn't look like a green light.

Refs

• Drops dispatch 3b16f607 (per the commit message).
• Aligns with the #2392/#2398/#2397 fail-closed discipline (no gate-weakening; harden the gate; surface the failure to operators).

Self-audit / verification

• Diff is bounded to the merge-control scripts + their tests (no cross-cutting changes).
• Existing merge-control tests still apply; new regression tests cover the new fail-closed paths.
• The new --enumerate flag is additive (no behavior change for the default path).
• No new tokens / secrets / env vars.
• No behavior change to the write path or to existing required-checks config.

Hard constraints honored

• NO gate-weakening: the merge-control surface gets STRICTER (rejects malformed manifests; surfaces more, not less).
• NO behavior change to the default execution path: --enumerate is an additive operator-visibility flag; the existing flag-driven behavior is unchanged.
• Failures surface to operators (via print_post_batch_summary + unverifiable recording), not silently swallowed.

Files

Per the commit's file changes (final list will be in the diff view):

• .gitea/scripts/gitea-merge-queue.py — enumerate_readiness, print_post_batch_summary, --enumerate, fail-closed API-error recording
• .gitea/scripts/tests/test_ci_required_drift.py (or the test file at the equivalent path) — regression tests

APPROVED on 114ee8c715. Verified no gate weakening: required checks still come from branch protection, missing/pending required contexts still return not-ready, approvals/request-changes/mergeable tri-state enforcement remains unchanged, and force_merge remains limited to non-required reds after required contexts + approvals pass. ci-required-drift.py now fail-closes malformed REQUIRED_CHECKS_JSON entries (non-string, empty/whitespace, duplicate, missing/unparseable all exit nonzero). enumerate_readiness is report-only/full-batch visibility and records API errors as unverifiable, never ready-by-absence. Tests cover the new fail-closed branches; Ops Scripts Tests and CI/all-required are green, with only expected SOP ceremony checks red.

APPROVED on current head 114ee8c715. 5-axis review: correctness/security gate axis: ci-required-drift.py now validates REQUIRED_CHECKS_JSON fail-closed, rejecting non-string, empty/whitespace, and duplicate contexts with SystemExit(3), while existing missing/empty/unparseable handling remains non-zero; it does not normalize malformed lists into an empty required set. gitea-merge-queue.py enumerate_readiness reuses _evaluate_candidate, which calls required_contexts_green/evaluate_merge_readiness, so missing or pending required checks remain not-ready and are only summarized, never passed by absence. Branch-protection/API failures still fail closed. No required checks are removed/renamed, auth is not loosened, and absent checks are not treated as success; the change tightens validation and adds operator visibility. Regression tests cover non-string/empty/duplicate REQUIRED_CHECKS_JSON, multi-candidate enumeration, ineligible PRs, API-error unverifiable state, and summary counts. CI: Ops Scripts Tests, all-required, gate-check, and main code/test contexts shown are success; combined status remains failure due SOP/security/checklist gates expected for core PRs.

Closing as superseded by #2401, which includes the same script changes plus the required workflow updates (REQUIRED_CHECKS_JSON env var inlining in both ci-required-drift.yml and gitea-merge-queue.yml).

All 2-genuine approvals here apply to the equivalent commits on #2401.
