# AGENTS
## Role
Canonical persistence for raw documents, DTOs, canonical advisories, jobs, and state. Provides repositories and bootstrapper for collections/indexes.
## Scope
- Collections (MongoStorageDefaults): source, source_state, document, dto, advisory, alias, affected, reference, kev_flag, ru_flags, jp_flags, psirt_flags, merge_event, export_state, locks, jobs; GridFS bucket fs.documents; field names include ttlAt (locks), sourceName, uri, advisoryKey.
- Records: SourceState (cursor, lastSuccess/error, failCount, backoffUntil), JobRun, MergeEvent, ExportState, Advisory documents mirroring Models with embedded arrays when practical.
- Bootstrapper: create collections, indexes (unique advisoryKey, scheme/value, platform/name, published, modified), TTL on locks, and validate connectivity for /ready health probes.
- Job store: create, read, mark completed/failed; compute durations; recent/last queries; active by status.
- Advisory store: CRUD for canonical advisories; query by key/alias and list for exporters with deterministic paging.
## Participants
- Core jobs read/write runs and leases; WebService /ready pings database; /jobs APIs query runs/definitions.
- Source connectors store raw docs, DTOs, and mapped canonical advisories with provenance; Update SourceState cursor/backoff.
- Exporters read advisories and write export_state.
## Interfaces & contracts
- IMongoDatabase injected; MongoUrl from options; database name from options or MongoUrl or default "concelier".
- Repositories expose async methods with CancellationToken; deterministic sorting.
- All date/time values stored as UTC; identifiers normalized.
## In/Out of scope
In: persistence, bootstrap, indexes, basic query helpers.
Out: business mapping logic, HTTP, packaging.
## Observability & security expectations
- Log collection/index creation; warn on existing mismatches.
- Timeouts and retry policies; avoid unbounded scans; page reads.
- Do not log DSNs with credentials; redact in diagnostics.
## Tests
- Author and review coverage in `../StellaOps.Concelier.Storage.Mongo.Tests`.
- Shared fixtures (e.g., `MongoIntegrationFixture`, `ConnectorTestHarness`) live in `../StellaOps.Concelier.Testing`.
- Keep fixtures deterministic; match new cases to real-world advisories or regression scenarios.


## Required Reading
- `docs/modules/concelier/architecture.md`
- `docs/modules/platform/architecture-overview.md`

## Working Agreement
- 1. Update task status to `DOING`/`DONE` in both correspoding sprint file `/docs/implplan/SPRINT_*.md` and the local `TASKS.md` when you start or finish work.
- 2. Review this charter and the Required Reading documents before coding; confirm prerequisites are met.
- 3. Keep changes deterministic (stable ordering, timestamps, hashes) and align with offline/air-gap expectations.
- 4. Coordinate doc updates, tests, and cross-guild communication whenever contracts or workflows change.
- 5. Revert to `TODO` if you pause the task without shipping changes; leave notes in commit/PR descriptions for context.
