Task ID | State | Task description | Owners (Source)
--- | --- | --- | ---
EXCITITOR-LNM-21-001 `Observation & linkset stores` | DONE | Stand up `vex_observations` and `vex_linksets` collections with shard keys, tenant guards, and migrations that retire any residual merge-era data without mutating raw content. | Excititor Storage Guild (src/Excititor/__Libraries/StellaOps.Excititor.Storage.Mongo)
EXCITITOR-LNM-21-002 `Conflict annotations` | DONE | Capture disagreement metadata (status + justification deltas) directly inside linksets with confidence scores so downstream consumers can highlight conflicts without Excititor choosing winners. Depends on EXCITITOR-LNM-21-001. | Excititor Core Guild (src/Excititor/__Libraries/StellaOps.Excititor.Core)
EXCITITOR-LNM-21-003 `Event emission` | DONE | Emit `vex.linkset.updated` events and describe payload shape (observation ids, confidence, conflict summary) so Policy/Lens/UI can subscribe while Excititor stays aggregation-only. Depends on EXCITITOR-LNM-21-002. | Excititor Core Guild, Platform Events Guild (src/Excititor/__Libraries/StellaOps.Excititor.Core)
EXCITITOR-LNM-21-201 `Observation APIs` | DONE | Ship `/vex/observations` read endpoints with filters for advisory/product/issuer, strict RBAC, and deterministic pagination (no derived verdict fields). Depends on EXCITITOR-LNM-21-003. | Excititor WebService Guild (src/Excititor/StellaOps.Excititor.WebService)
EXCITITOR-LNM-21-202 `Linkset APIs` | DONE | Provide `/vex/linksets` + export endpoints that surface alias mappings, conflict markers, and provenance proofs exactly as stored; errors must map to `ERR_AGG_*`. Depends on EXCITITOR-LNM-21-201. | Excititor WebService Guild (src/Excititor/StellaOps.Excititor.WebService)
EXCITITOR-LNM-21-203 `Docs & SDK examples` | DONE | Update OpenAPI, SDK smoke tests, and documentation to cover the new observation/linkset endpoints with realistic examples Advisory AI/Lens teams can rely on. Depends on EXCITITOR-LNM-21-202. | Excititor WebService Guild, Docs Guild (src/Excititor/StellaOps.Excititor.WebService)
EXCITITOR-OBS-51-001 `Metrics & SLOs` | DONE | Publish ingest latency, scope resolution success, conflict rate, and signature verification metrics plus SLO burn alerts so we can prove Excititor meets the AOC "evidence freshness" mission. | Excititor Core Guild, DevOps Guild (src/Excititor/__Libraries/StellaOps.Excititor.Core)
