 # Link-Not-Merge (LNM) Observation & Linkset Schema
 
-_Draft for approval — authored 2025-11-16 to unblock CONCELIER-LNM tracks._
+_Frozen v1 (add-only) — approved 2025-11-17 for CONCELIER-LNM-21-001/002/101._
 
 ## Goals
 - Immutable storage of raw advisory observations per source/tenant.
 - Deterministic linksets built from observations without merging or mutating originals.
 - Stable across online/offline deployments; replayable from raw inputs.
 
+## Status
+- Frozen v1 as of 2025-11-17; further schema changes must go through ADR + sprint gating (CONCELIER-LNM-22x+).
