homelab-integration.md gains a "Scheduled discovery" section documenting TAPIR_DISCOVERY_INTERVAL and TAPIR_FETCH_RATE and the load-bearing single-replica constraint (in-process scheduler → replicas: 1 is required; >1 double-runs discovery). VISION Stage 0 carries a pointer to ADR-018's gate-clock reset so nothing in docs implies the window started before unprompted use was possible.
