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.
