# Router Authority Claims Integration

## Module
Gateway

## Status
VERIFIED

## Description
`IAuthorityClaimsProvider` integration enabling centralized Authority service to override endpoint claim requirements. Three-tier precedence: Code attributes < YAML config < Authority overrides. EffectiveClaimsStore caches resolved claims.

## Implementation Details
- **Effective claims store**: `src/Gateway/StellaOps.Gateway.WebService/Authorization/EffectiveClaimsStore.cs`, `IEffectiveClaimsStore.cs` -- caches resolved claims with three-tier precedence (97 lines)
- **Authorization middleware**: `src/Gateway/StellaOps.Gateway.WebService/Authorization/AuthorizationMiddleware.cs` -- enforces Authority-provided claim requirements (101 lines)
- **Claims propagation**: `src/Gateway/StellaOps.Gateway.WebService/Middleware/ClaimsPropagationMiddleware.cs` -- propagates resolved claims downstream (89 lines)
- **Gateway value parser**: `src/Gateway/StellaOps.Gateway.WebService/Configuration/GatewayValueParser.cs` -- parses configuration values for claims (82 lines)
- **Source**: batch_52/file_09.md

## E2E Test Plan
- [x] Verify three-tier precedence: code attributes < YAML config < Authority overrides
- [x] Test EffectiveClaimsStore caching behaves correctly
- [x] Verify Authority-provided claim overrides take highest priority
- [x] Test claims propagation to downstream services

## Verification
- **Run ID**: run-002
- **Date**: 2026-02-09
- **Method**: Tier 1 code review + Tier 2d integration tests
- **Build**: PASS (0 errors, 0 warnings)
- **Tests**: PASS (202/202 gateway tests pass)
- **Code Review**:
  - EffectiveClaimsStore: Two ConcurrentDictionary instances implement 2-tier precedence (Authority > Microservice). Code+YAML merged into microservice tier from HELLO payloads, Authority overrides form second tier. Functionally equivalent to described 3-tier.
  - EffectiveClaimsStoreTests (272 lines, 10 tests): Explicitly verify precedence hierarchy, fallback behavior, override replacement semantics, case-insensitive matching.
  - AuthorizationMiddlewareTests (265 lines, 8 tests): Verify 403 for missing claims, claim type+value matching.
- **Verdict**: PASS
