Extends ADR-084's RaBitQ-as-similarity-sensor pattern from five sites
to twelve, adding seven additional pipeline locations the user
identified during ADR-084 implementation:
- Per-room adaptive classifier short-circuit (Mahalanobis prefilter)
- Recording-search REST endpoint (GET /api/v1/recordings/similar)
- WiFi BSSID fingerprinting (channel-hop scheduler input)
- mmWave (LD2410 / MR60BHA2) signature wake-gate
- Witness bundle drift detection (CI ratchet)
- Agent / swarm memory routing (ADR-066 swarm bridge)
- Log / event-pattern anomaly detection (cluster Pi)
Each site has a 2-3 sentence decision (what gets sketched, what
triggers the comparison, what the refinement does on miss) and a
witness-hash artifact (what the system stores in place of the raw
embedding/event/signal).
Implementation plan ordered cheapest-first / least-risky-first.
Acceptance criteria align with ADR-084 (8x-30x compare cost,
≥90% top-K coverage, <1pp accuracy regression) where applicable;
non-vector sites (witness bundle, BSSID time-series, event log)
have site-specific criteria.
Three open questions explicitly flagged:
1. Mahalanobis-after-binary-sketch is novel — no published primary
source found, marked conjecture, decision deferred to bench
2. Canonical "non-vector → sketchable" encoding is unsolved
3. MERIDIAN (ADR-027) cross-environment domain interaction needs
site-by-site analysis before bank rebuild semantics are committed
Status: Proposed. SOTA review by goal-planner agent.
