# StellaOps Authority

Authority is the platform OIDC/OAuth2 control plane that mints short-lived, sender-constrained operational tokens (OpToks) for every StellaOps service and tool.

## Responsibilities
- Expose device-code, auth-code, and client-credential flows with DPoP or mTLS binding.
- Manage signing keys, JWKS rotation, and PoE integration for plan enforcement.
- Emit structured audit events and enforce tenant-aware scope policies.
- Provide plugin surface for custom identity providers and credential validators.

## Key components
- `StellaOps.Authority` web host.
- `StellaOps.Authority.Plugin.*` extensions for secret stores, identity bridges, and OpTok validation.
- Telemetry and audit pipeline feeding Security/Observability stacks.

## Integrations & dependencies
- Signer/Attestor for PoE and OpTok introspection.
- CLI/UI for login flows and token management.
- Scheduler/Scanner for machine-to-machine scope enforcement.

## Operational notes
- MongoDB for tenant, client, and token state.
- Key material in KMS/HSM with rotation runbooks (see ./operations/key-rotation.md).
- Grafana/Prometheus dashboards for auth latency/issuance.

## Epic alignment
- **Epic 1 – AOC enforcement:** enforce OpTok scopes and guardrails supporting raw ingestion boundaries.
- **Epic 2 – Policy Engine & Editor:** supply policy evaluation/principal scopes and short-lived tokens for evaluator workflows.
- **Epic 4 – Policy Studio:** integrate approval/promotion signatures and policy registry access controls.
- **Epic 14 – Identity & Tenancy:** deliver tenant isolation, RBAC hierarchies, and governance tooling for authentication.
