  "notes": "Already blocking: this gate is an existing scripts/doctor.cjs acceptance point (id worktree-hygiene, severity blocker) invoked with --check --json exactly as declared here, so declaring it at rung blocking is a transcription, not a behavior change. No evidence log exists for it today (34 of 35 gates lack one), so promotion_rule is decided now, before any log exists, and is retained for schema completeness and for a future demotion-then-repromotion review, never for an upcoming promotion since blocking is already the ceiling rung."
