# TASKS — Epic 1: Aggregation-Only Contract
> **AOC Reminder:** ingestion aggregates and links only—no precedence, normalization, or severity computation. Derived data lives in Policy/overlay services.
| ID | Status | Owner(s) | Depends on | Notes |
|---|---|---|---|---|
| CONCELIER-CORE-AOC-19-001 `AOC write guard` | DONE (2025-10-29) | Concelier Core Guild | WEB-AOC-19-001 | Implement repository interceptor that inspects write payloads for forbidden AOC keys, validates provenance/signature presence, and maps violations to `ERR_AOC_00x`. |
> Docs alignment (2025-10-26): Behaviour/spec captured in `docs/ingestion/aggregation-only-contract.md` and architecture overview §2.
> Implementation (2025-10-29): Added `AdvisoryRawWriteGuard` + DI extensions wrapping `AocWriteGuard`, throwing domain-specific `ConcelierAocGuardException` with `ERR_AOC_00x` mappings. Unit tests cover valid/missing-tenant/signature cases.
> Coordination (2025-10-27): Authority `dotnet test` run is currently blocked because `AdvisoryObservationQueryService.BuildAliasLookup` returns `ImmutableHashSet<string?>`; please normalise these lookups to `ImmutableHashSet<string>` (trim nulls) so downstream builds succeed.
| CONCELIER-CORE-AOC-19-002 `Deterministic linkset extraction` | DONE (2025-10-31) | Concelier Core Guild | CONCELIER-CORE-AOC-19-001 | Build canonical linkset mappers for CVE/GHSA/PURL/CPE/reference extraction from upstream raw payloads, ensuring reconciled-from metadata is tracked and deterministic. |
> 2025-10-31: Added advisory linkset mapper + DI registration, normalized PURL/CPE canonicalization, persisted `reconciled_from` pointers, and refreshed observation factory/tests for new raw linkset shape.
> Docs alignment (2025-10-26): Linkset expectations detailed in AOC reference §4 and policy-engine architecture §2.1.
| CONCELIER-CORE-AOC-19-003 `Idempotent append-only upsert` | DONE (2025-10-28) | Concelier Core Guild | CONCELIER-STORE-AOC-19-002 | Implement idempotent upsert path using `(vendor, upstreamId, contentHash, tenant)` key, emitting supersedes pointers for new revisions and preventing duplicate inserts. |
> 2025-10-28: Advisory raw ingestion now strips client-supplied supersedes hints, logs ignored pointers, and surfaces repository-supplied supersedes identifiers; service tests cover duplicate handling and append-only semantics.
> Docs alignment (2025-10-26): Deployment guide + observability guide describe supersedes metrics; ensure implementation emits `aoc_violation_total` on failure.
| CONCELIER-CORE-AOC-19-004 `Remove ingestion normalization` | DOING (2025-10-28) | Concelier Core Guild | CONCELIER-CORE-AOC-19-002, POLICY-AOC-19-003 | Strip normalization/dedup/severity logic from ingestion pipelines, delegate derived computations to Policy Engine, and update exporters/tests to consume raw documents only. |
> Docs alignment (2025-10-26): Architecture overview emphasises policy-only derivation; coordinate with Policy Engine guild for rollout.
| CONCELIER-CORE-AOC-19-013 `Authority tenant scope smoke coverage` | TODO | Concelier Core Guild | AUTH-AOC-19-002 | Extend Concelier smoke/e2e fixtures to configure `requiredTenants` and assert cross-tenant rejection with updated Authority tokens. | Coordinate deliverable so Authority docs (`AUTH-AOC-19-003`) can close once tests are in place. |

## Policy Engine v2

| ID | Status | Owner(s) | Depends on | Notes |
|----|--------|----------|------------|-------|
| CONCELIER-POLICY-20-002 `Linkset enrichment for policy` | TODO | Concelier Core Guild, Policy Guild | CONCELIER-CORE-AOC-19-002, POLICY-ENGINE-20-001 | Strengthen linkset builders with vendor-specific equivalence tables, NEVRA/PURL normalization, and version range parsing to maximize policy join recall; update fixtures + docs. |
> 2025-10-31: Base advisory linkset mapper landed under `CONCELIER-CORE-AOC-19-002`; policy enrichment work can now proceed with mapper outputs and observation schema fixtures.

## Graph Explorer v1

| ID | Status | Owner(s) | Depends on | Notes |
|----|--------|----------|------------|-------|
| CONCELIER-GRAPH-21-001 `SBOM projection enrichment` | BLOCKED (2025-10-27) | Concelier Core Guild, Cartographer Guild | CONCELIER-POLICY-20-002, CARTO-GRAPH-21-002 | Extend SBOM normalization to emit full relationship graph (depends_on/contains/provides), scope tags, entrypoint annotations, and component metadata required by Cartographer. |
> 2025-10-27: Waiting on policy-driven linkset enrichment (`CONCELIER-POLICY-20-002`) and Cartographer API contract (`CARTO-GRAPH-21-002`) to define required relationship payloads. Without those schemas the projection changes cannot be implemented deterministically.
| CONCELIER-GRAPH-21-002 `Change events` | BLOCKED (2025-10-27) | Concelier Core Guild, Scheduler Guild | CONCELIER-GRAPH-21-001 | Publish change events (new SBOM version, relationship delta) for Cartographer build queue; ensure events include tenant/context metadata. |
> 2025-10-27: Depends on `CONCELIER-GRAPH-21-001`; event schema hinges on finalized projection output and Cartographer webhook contract, both pending.

> 2025-10-29: Filter-aware lookup path and /concelier/observations coverage landed; overlay services can consume raw advisory feeds deterministically.

| ID | Status | Owner(s) | Depends on | Notes |
