# TASKS
| Task | Owner(s) | Depends on | Notes |
|---|---|---|---|
|MongoBootstrapper to create collections/indexes|BE-Storage|Storage.Mongo|DONE – `MongoBootstrapper` ensures collections & indexes incl. TTL on locks.ttlAt.|
|SourceState repository (get/set/backoff)|BE-Conn-Base|Storage.Mongo|DONE – implemented `MongoSourceStateRepository`.|
|Document/DTO stores with SHA/metadata|BE-Conn-Base|Storage.Mongo|DONE – DocumentStore and DtoStore provide upsert/status lookups.|
|AdvisoryStore (GetAllAsync etc.)|BE-Export|Models|DONE – AdvisoryStore handles upsert + recent/advisory fetches.|
|Job store (runs/active/recent)|BE-Core|Storage.Mongo|DONE – `MongoJobStore` covers create/start/complete queries.|
|Alias and reference secondary indexes|BE-Storage|Models|DONE – bootstrapper builds alias/reference indexes.|
|MergeEvent store|BE-Merge|Models|DONE – MergeEventStore appends/retrieves recent events.|
|ExportState store|BE-Export|Exporters|DONE – ExportStateStore upserts and retrieves exporter metadata.|
|Performance tests for large advisories|QA|Storage.Mongo|DONE – `AdvisoryStorePerformanceTests` exercises large payload upsert/find throughput budgets.|
|Migration playbook for schema/index changes|BE-Storage|Storage.Mongo|DONE – `MongoMigrationRunner` executes `IMongoMigration` steps recorded in `schema_migrations`; see `MIGRATIONS.md`.|
|Raw document retention/TTL strategy|BE-Storage|Storage.Mongo|DONE – retention options flow into `RawDocumentRetentionService` and TTL migrations for `document`/GridFS indexes.|
|Persist last failure reason in SourceState|BE-Storage|Storage.Mongo|DONE – `MongoSourceStateRepository.MarkFailureAsync` stores `lastFailureReason` with length guard + reset on success.|
|AdvisoryStore range primitives deserialization|BE-Storage|Models|DONE – BSON helpers handle `RangePrimitives`; regression test covers SemVer/NEVRA/EVR envelopes persisted through Mongo.|
|FEEDSTORAGE-DATA-03-001 Merge event provenance audit prep|BE-Storage|Merge|DONE – merge events now persist field-level decision reasons via `MergeFieldDecision` documents for analytics. **Coordination:** log any new precedence signals to storage@ so indexes/serializers stay aligned.|
|FEEDSTORAGE-DATA-02-001 Normalized range dual-write + backfill|BE-Storage|Core|**DONE (2025-10-12)** – `AdvisoryStore` honors `EnableSemVerStyle`, dual-writes normalized docs, and SemVer backfill migration registered for staged rollout.|
|FEEDSTORAGE-TESTS-02-004 Restore AdvisoryStore build after normalized versions refactor|QA|Storage.Mongo|DONE – storage tests updated to cover normalized version payloads and new provenance fields. **Heads-up:** QA to watch for fixture bumps touching normalized rule arrays when connectors roll out support.|
|FEEDSTORAGE-DATA-02-002 Provenance decision persistence|BE-Storage|Models `FEEDMODELS-SCHEMA-01-002`|**DONE (2025-10-12)** – Normalized documents carry decision reasons/source/timestamps with regression coverage verifying SemVer notes + provenance fallbacks.|
|FEEDSTORAGE-DATA-02-003 Normalized versions index creation|BE-Storage|Normalization, Mongo bootstrapper|**DONE (2025-10-12)** – Bootstrapper seeds `normalizedVersions.*` indexes when SemVer style is enabled; docs/tests confirm index presence.|
|FEEDSTORAGE-DATA-04-001 Advisory payload parity (description/CWEs/canonical metric)|BE-Storage|Models, Core|DONE (2025-10-15) – Mongo payloads round-trip new advisory fields; serializer/tests updated, no migration required beyond optional backfill.|
|FEEDSTORAGE-MONGO-08-001 Causal-consistent session plumbing|BE-Storage|Concelier Core DI|TODO – Introduce scoped MongoDB session provider enabling causal consistency + majority read/write concerns in `AddMongoStorage`; flow optional `IClientSessionHandle` through job/advisory/source state/document stores; add integration test simulating primary election to prove read-your-write + monotonic reads.|
|FEEDSTORAGE-DATA-07-001 Advisory statement & conflict collections|Team Normalization & Storage Backbone|FEEDMERGE-ENGINE-07-001|TODO – Create `advisory_statements` (immutable) and `advisory_conflicts` collections, define `asOf`/`vulnerabilityKey` indexes, and document migration/rollback steps for event-sourced merge.|
