# AGENTS
## Role
Minimal API host wiring configuration, storage, plugin routines, and job endpoints. Operational surface for health, readiness, and job control.
## Scope
- Configuration: appsettings.json + etc/concelier.yaml (yaml path = ../etc/concelier.yaml); bind into ConcelierOptions with PostgreSQL storage enabled by default.
- Storage: PostgreSQL only (`Concelier:PostgresStorage:*`). No MongoDB/Mongo2Go; readiness probes issue `SELECT 1` against ConcelierDataSource.
- Services: AddConcelierPostgresStorage(); AddSourceHttpClients(); RegisterPluginRoutines(configuration, PluginHostOptions).
- Bootstrap: PostgreSQL connectivity verified on startup.
- Endpoints (configuration & job control only; root path intentionally unbound):
- GET /health -> {status:"healthy"} after options validation binds.
- GET /ready -> PostgreSQL connectivity check; degraded if connection fails.
- GET /jobs?kind=&limit= -> recent runs.
- GET /jobs/{id} -> run detail.
- GET /jobs/definitions -> definitions with lastRun.
- GET /jobs/definitions/{kind} -> definition + lastRun or 404.
- GET /jobs/definitions/{kind}/runs?limit= -> recent runs or 404 if kind unknown.
- GET /jobs/active -> currently running.
- POST /jobs/{*jobKind} with {trigger?,parameters?} -> 202 Accepted (Location:/jobs/{runId}) | 404 | 409 | 423.
- PluginHost defaults: BaseDirectory = solution root; PluginsDirectory = "StellaOps.Concelier.PluginBinaries"; SearchPatterns += "StellaOps.Concelier.Plugin.*.dll"; EnsureDirectoryExists = true.
## Participants
- Core job system; Storage.Postgres; Source.Common HTTP clients; Exporter and Connector plugin routines discover/register jobs.
## Interfaces & contracts
- Dependency injection boundary for all connectors/exporters; IOptions<ConcelierOptions> validated on start.
- Cancellation: pass app.Lifetime.ApplicationStopping to bootstrapper.
## In/Out of scope
In: hosting, DI composition, REST surface, readiness checks.
Out: business logic of jobs, HTML UI, authn/z (future).
## Observability & security expectations
- Log startup config (redact DSN credentials), plugin scan results (missing ordered plugins if any).
- Structured responses with status codes; no stack traces in HTTP bodies; errors mapped cleanly.
## Tests
- Author and review coverage in `../StellaOps.Concelier.WebService.Tests`.
- Shared fixtures (PostgreSQL-backed harnesses) 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.
