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 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.
