Remove the `schedule:` trigger from gitea-merge-queue.yml (execution absorbed into the operator conductor)

Measurement (Gitea DB action_run_job, 7d, posted on operator-config#157): the scheduled queue job is the top remaining CI meta-job after event-driven dispatch (operator-config#157/#159): 312 jobs/hr around the clock across 26 repos (288/day in this repo alone) = ~52.4k container jobs/week, ~58–65 in-job hours/week plus a full container lifecycle per tick — and ~99% of ticks are no-ops ("merge queue empty" / fail-closed holds; verified in this fleet's action logs).

What replaced it: since operator-config#194 (merged + autoheal-applied), the operator conductor tick (molecule-core-cron-bot.sh conductor, every 5 min — same cadence as this schedule) runs this repo's merge-queue in-process, with this repo's own workflow env and this repo's own script version (parsed/fetched per tick, sha256-pinned before execution). Live parity was proven before this PR was opened: the conductor pass reproduces this repo's scheduled-run behavior exactly.

This PR changes no policy: the queue contract, merge bar, labels, and workflow_dispatch (manual run) are untouched. Only the schedule: block is removed so the 5-min container polling stops.

Kill-switch / rollback:

Conductor-side: touch /etc/molecule-bootstrap/molecule-ci-conductor-fleet.disabled (operator host) — disables the in-process pass.
Repo-side: revert this PR (re-adds schedule: - cron: "*/5 * * * *"); workflow_dispatch works at any time.

Projected saving for this repo: ~2,016 scheduler jobs/week.

SOP checklist

Comprehensive testing performed — change is a workflow-trigger removal (no code/logic). Verified: (a) transformed YAML parses and workflow_dispatch retained, validated programmatically for all 26 repos before opening; (b) the replacement (conductor fleet pass, operator-config#194) proven live: dry + real runs reproduce this repo's scheduled-job behavior byte-for-byte (same script version, same env, same fail-closed outcomes), full installed-path conductor tick green (status-reaper rc=0, merge-queue rc=0, merge-queue-fleet rc=0, journal 2026-06-10T10:12:58Z).
Local-postgres E2E run — N/A: CI workflow trigger change only, no application/database code.
Staging-smoke verified or pending — the conductor fleet pass is already live on the operator host (autoheal-applied 2026-06-10T09:40Z) and has been observed processing this repo class in production while the schedule still runs in parallel; removing schedule: only stops the redundant container polling.
Root-cause not symptom — root cause: schedule-based polling burns a full CI container lifecycle every 5 min per repo (~52k jobs/week fleet-wide, ~99% no-ops) for work an existing operator-side tick can do in-process; this PR removes the polling vehicle, not the queue policy.
Five-Axis review walked — correctness: YAML validated + behavior parity proven; readability: in-file note documents the absorption + rollback; architecture: execution moved to the conductor (operator-config#158 pattern), policy untouched; security: workflow loses its schedule-time token use, conductor side sha256-pins script bytes; performance: removes ~2,016 scheduler jobs/week for this repo.
No backwards-compat shim / dead code added — yes, none: the schedule: block is deleted (not commented-as-fallback); workflow_dispatch is retained as the designed manual vehicle, not a shim.
Memory/saved-feedback consulted — gate semantics are CTO-governed (absorb execution, never policy); kill-switch + rollback in every change; verify the real artifact (live conductor tick observed, not assumed); parallel-work check done (no competing PRs touch this file).

qa APPROVE (5-axis, MQ-3 gate-integrity verified). Change touches ONLY the on: trigger block of gitea-merge-queue.yml — removes the schedule: */5 cron, documents that the operator conductor (operator-config#194) now invokes the queue in-process every 5 min (the cron burned ~288 container-jobs/day/repo, ~52k/week fleet-wide, ~99% no-ops). GATE-INTEGRITY (the key axis): this does NOT weaken merge-queue enforcement — the required-check verification + 2-distinct-genuine gating lives in the job SCRIPT/STEPS, which are UNCHANGED; the trigger only controls invocation CADENCE, not what the gating does when it runs. No bypass introduced — workflow_dispatch is an invocation vehicle, the gating still runs regardless of invocation source. Correctness/robustness: sound; the only trade-off is liveness now depends on the operator conductor — which is fail-SAFE (queue STALLS rather than bad-merges) and has a documented kill-switch + manual workflow_dispatch fallback + rollback. Security: no token/permission delta (permissions block unchanged). Content-security: only an internal operator host PATH in a comment (no creds) — clean. CI green, mergeable. NON-BLOCKING sequencing note: this assumes the operator conductor (operator-config#194) is LIVE and ticking before the cron is removed — if it's not yet deployed, the queue would go dark until it is; worth confirming conductor-live as these merge. Approving.

Security 5-axis — APPROVE (head a05c067879). ci: remove gitea-merge-queue schedule: cron — the operator conductor now runs the queue in-process every 5 min (operator-config#194). 2nd distinct lane (CR-B holds 1st).

Gate-integrity (this touches the merge-queue workflow — scrutinized hard): the change is ONLY to the on: trigger (drop schedule: */5, keep workflow_dispatch). The merge-queue JOB/script (the gitea-merge-queue.py gate-check + merge logic) is UNCHANGED — same required-approval/required-context enforcement, just invoked by the conductor instead of cron ("THIS repo's env + script version preserved"). No merge-gate bypass, no weakening of approval/context checks. ✓
Security/content-security: workflow-trigger config only; no secrets, no permissions: change (block unchanged). The documented kill-switch path + rollback are operator-host ops-records in an internal CI comment (appropriate ops disclosure, not a tenant-reachable attack surface). ✓
Performance (the point): removes ~288 container jobs/day/repo (~52k/week fleet-wide, ~99% no-ops) — real CI-resource savings; also relieves the runner-pool pressure tracked on #2514/Face-A. ✓
Robustness/Readability: comment documents rationale + measurement + kill-switch + full rollback (restore the schedule block). workflow_dispatch remains as manual fallback. ✓
Non-blocking (operational sequencing): this presumes the operator conductor is LIVE and invoking this queue per-repo; if it is not yet wired, queued PRs would stall — mitigated by the retained workflow_dispatch manual fallback + the documented rollback. Recommend confirming conductor-live before/with the merge.
Gate GREEN (all 4 CI contexts ✓ incl Workflow-YAML-lint (validates the edited workflow), Secrets-scan). Author devops-engineer ≠ me. Clean trigger-cleanup — APPROVE.
