# Mergify merge queue — WS3.4/D5 of the v3.8.49 quality/velocity master plan.
#
# WHY: ~85-100 active PR authors/month and 300+ PRs/week peaks, all merged by ONE
# identity. The manual merge-train validated batches by hand; this queue automates
# it with batching + automatic batch bisection (a red batch of N costs ~log2(N)
# revalidations instead of N). Mergify Open Source plan: free, unlimited, public repo.
#
# GOVERNANCE (non-negotiable, mirrors CLAUDE.md Hard Rules #21/#22 + the owner's
# pre-merge ⭐ gate):
# • A PR enters the queue ONLY via the `queue` label — applied by the owner (or a
# session acting for the owner) AFTER the pre-merge ⭐ report/decision. The label
# IS the merge approval; Mergify only executes it.
# • During a release-freeze (open issue labeled `release-freeze`), do NOT label PRs
# targeting the frozen branch — the freeze is a human-honored coordination signal
# the queue cannot see. Retarget to the active release/vX+1 first (Hard Rule #21).
# • Never label a PR another session is actively working (Hard Rule #22b).
# • Fallback path if Mergify misbehaves or the OSS plan changes: the manual
# merge-train runbook (docs/ops/MERGE_TRAIN.md) — remove labels, proceed by hand.
# Auto-enqueue (current Mergify model, 2026): auto_merge_conditions in
# merge_protections_settings — the rules-based queue action / autoqueue path is
# deprecated (EOL 2026-07-16). The owner-applied `queue` label IS the approval.
merge_protections_settings:
auto_merge_conditions:
- label = queue
queue_rules:
- name: release
# Any current or future release branch — the reason GitHub's native queue was
# rejected (no wildcard support on personal-account repos).
queue_conditions:

- label=queue
- -draft
- -conflict
# "Everything that ran is green, nothing still running, AND the always-on
# anchor check succeeded" — robust to the path-filtered fast-gates (docs-only
# PRs skip code jobs; matrix shard names vary) while never fail-open: a PR with
# zero checks cannot vacuously merge, because `Merge integrity` runs on EVERY
# non-draft PR (quality.yml) and must be an affirmative success. Review approval
# is intentionally NOT a condition here: the owner-applied `queue` label IS the
# approval in this repo's single-maintainer model (see governance header).
merge_conditions:
# "Zero failures" — EXCEPT the advisory dast-smoke: it is continue-on-error by
# design and its GH-hosted CLI build hangs recurrently (drafts #7184/#7221 were
# dequeued solely by it). Any OTHER failure still blocks (anti-fail-open kept).

- "#check-failure=0"

# NO batching: 'Merge Queue Batch' requires a paid Mergify tier (live finding
# 2026-07-15 — the queue command fails with "Cannot use Merge Queue batch" on
# the free plan). Serial queue (1 PR at a time) still automates the train.
# Squash keeps the one-commit-per-PR history the CHANGELOG reconciliation expects.
