StellaOps Authority — Authentication Libraries Team
Read first:
AGENTS.md,StellaOps.Authority.TODOS.md, and this plan. Keep status synchronized across trackers.
Mission
Deliver shared authentication components consumed by resource servers, clients, and tooling: abstractions, DI helpers, token clients, and supporting utilities.
Task Breakdown
| Order | Task IDs | Description | Dependencies | Acceptance | 
|---|---|---|---|---|
| 1 | LIB1 | Stand up StellaOps.Auth.Abstractions(claims, scopes, principal builder, ProblemResultFactory). | DevEx FND1 | Unit tests covering claim normalization + problem responses. | 
| 2 | LIB3 | Implement NetworkMaskMatcherwith IPv4/IPv6 CIDR support; port tests from Serdica inspiration. | LIB1 | 100% branch coverage on mask utilities. | 
| 3 | LIB2 | Build StellaOps.Auth.ServerIntegration(DI extension wiring JwtBearer, bypass masks, policy helpers). | LIB1, LIB3 | Add integration test with stub Authority JWKS. | 
| 4 | LIB4 | Build StellaOps.Auth.Client(discovery, JWKS caching, password/client credential flows, token cache abstraction). | LIB1 | Provide IStellaOpsTokenClientinterfaces. | 
| 5 | LIB5 | Integrate Polly + HttpClientFactory patterns (configurable retries/backoff) in Auth.Client. | LIB4 | Config tested via options binding. | 
| 6 | LIB6 | Prepare NuGet packaging metadata (license, tags) and update build pipeline to push once stabilized. | LIB1–LIB5 | Validate dotnet packoutputs signed packages. | 
Implementation Notes
- All option classes should bind via StellaOps.Configurationnaming conventions.
- Token client must support file-based cache (for CLI) and in-memory cache (for services).
- Provide sample usage snippets for Feedser integration (to hand off).
- Consider adding IClaimsTransformationhelper for ASP.NET resource servers.
- Ensure authentication failures map to standard problem responses (missing/expired token, insufficient scope).
Deliverables
- Three new projects: StellaOps.Auth.Abstractions,.ServerIntegration,.Client.
- Unit + integration tests, coverage reports.
- Example integration docs/snippets for Feedser and CLI teams.
- Packaging metadata ready for CI once green-lit.
Coordination
- Weekly sync with Authority Core + Feedser Integration to align on scopes/policies.
- Share NuGet package versions with DevEx once published.
- Notify CLI team when client API stabilizes (unlock CLI1–CLI3).
- Coordinate with Security Guild on bypass mask semantics and default policies.
Status (2025-10-10)
- LIB1 DONE – Principal builder/problem factory complete with unit coverage.
- LIB3 DONE – NetworkMaskMatcherreplaces Serdica helpers with IPv4/6 tests.
- LIB2 DONE – AddStellaOpsResourceServerAuthenticationwith scope/bypass policies implemented.
- LIB4 DONE – Auth client, discovery/JWKS caches, in-memory/file token caches with happy-path tests delivered.
