  "notes": "This gate wraps lib/core/doctor/graph-derive-health-module.cjs's detectRoomHealth (Canon Part 7 reuse before build: the SEED-037 4d derivation-health signal already ships, with two existing consumers, and this is a third consumer, never a second copy). The committed converged-room fixture has no room.db, so a run against it reports status skip, and skip is the correct green case, not a failure. Declared at rung logged for one release per requirement 5, promoted to blocking only by the D8 rule once a log exists and promotion_rule is met; it is the runner's first declared policy because SEED-037 established that Larry must never write into a graph nothing downstream derives."
