Snapshot

Reviewed overlay for SN57 using the official Sparket website and source repository. No official docs/API/OpenAPI surface is verified yet. This re-review pass re-verified all 5 surfaces live (no missing-probe gap found); confirmed sparket.ai/openapi.json is not a real schema (SPA HTML fallback). Observed the backend health endpoint reporting a real degraded/stale sync state and a single-source on-chain identity discrepancy ("gaia") uncorroborated by any live infrastructure -- see gap_notes.
