When to use: Perform a lightweight clash analysis between two Revit categories (e.g. Mechanical Equipment vs Structural Framing) using bounding-box overlap where available, falling back to shared-Level proximity, then annotate with any matching VDC rules stored in the D1 database. When NOT to use: Do not use as a substitute for Navisworks Manage for contractual clash reports — this is a first-pass coordination sniff test, not a certified Clash Detective run. APS scopes: data:read viewables:read (Model Derivative metadata + properties). Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable. Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — verify model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter. Side effects: Read-only against APS. May read from D1 vdc_rules table if present. Idempotent.
