Closes soc-ymph.3 — GOALS.md directive D3 (Quarantine-empty enforcement gate).
Why
- tests/_quarantine/ is meant to be an inbox, not a parking lot. Without a
gate, parked suites accumulate and the directive promise that "broken
tests get fixed or deleted" silently drifts.
What
- scripts/check-quarantine-empty.sh: new gate (exit 1 when find returns any
*.sh/*.bats under tests/_quarantine; exit 0 otherwise; ALLOW_QUARANTINE=1
env var for single-cycle operator override). Uses set -euo pipefail and
array-based output for portable enumeration.
- GOALS.md: new `quarantine-empty` row, weight 4 (mirrors bead spec).
goal_count 22 -> 23.
- .github/workflows/validate.yml: new validate-quarantine-empty job (no
changes filter — quarantine is shared infra, always check), registered
in summary.needs[] and summary echo. Per learning
2026-05-07-ci-workflow-additions-need-parity-co-execution, validated
via scripts/validate-ci-policy-parity.sh.
- AGENTS.md: CI Jobs table row for validate-quarantine-empty.
- scripts/pre-push-gate.sh: new check 22c (quarantine empty), always-on so
it catches pollution regardless of diff scope.
- tests/scripts/pre-push-gate.bats: stub check-quarantine-empty.sh per
test-fixture parity rule.
Verification
- bash scripts/check-quarantine-empty.sh -> PASS (empty)
- Synthetic populated dir -> exit 1 with file list
- ALLOW_QUARANTINE=1 override -> exit 0 with SKIP banner
- ao goals measure -> quarantine-empty result=pass, weight=4
- bash scripts/validate-ci-policy-parity.sh -> PASS (49 jobs, 7 non-blocking)
- bash scripts/pre-push-gate.sh --fast Pass 1 -> PASSED
