Summary

• Adds unit test covering mid-session ceiling breach via getAccessTokenSilently
• Adds Session Expiry from Upstream IdP (IPSIE) section to EXAMPLES.md

Test plan

• All existing unit tests pass
• New session_expiry ceiling (IPSIE SL1) test passes

Summary by CodeRabbit

• Bug Fixes
  • Authentication state now refreshes when a silent token request returns no token, keeping session and user information current.
  • Protected requests now report a missing_token error when no token is available, while anonymous requests can proceed without authorization.
• Documentation
  • Added guidance on upstream identity-provider session expiry, including expiry behavior, token requests, and claim handling.

📝 Walkthrough

The change documents the session_expiry ID-token claim and its effects. It also refreshes authentication state when a silent token request returns no token, with tests for service state changes and interceptor behavior.

Changes: Upstream IdP session expiry

Layer / File(s)	Summary
Document and validate session-expiry behavior EXAMPLES.md, projects/auth0-angular/src/lib/auth.service.ts, projects/auth0-angular/src/lib/auth.service.spec.ts, projects/auth0-angular/src/lib/auth.interceptor.spec.ts	Documentation describes the session_expiry claim, expiry behavior, and null handling. When a silent token request returns no token, the service refreshes authentication state. Tests cover authentication and user state changes, plus the interceptor’s missing_token error.

Merge Risk: 🔵 Low · up to 258e8

The documentation example will not compile for Angular 13–16 consumers, although the impact is limited to users copying this example.

Security architecture risk: 🔵 Low · up to 258e8

The change uses the existing authentication-state owner and preserves protected HTTP request handling. No new authorization bypass was identified. Expiry and recovery timing remain incompletely verified, so token-request completion should not be treated as an atomic identity-state transition.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated impact is within an application's authentication-state consumers, including route guards and identity displays. The inspected change adds no credential authority or cross-service dependency; exposure in external consuming applications was not inventoried.

Trust Boundaries and Controls

• observed — An empty token does not itself assert a new identity or grant access. State is re-read from the client, and the unchanged HTTP boundary requires a token for protected configured routes. Anonymous continuation remains an explicit route configuration.

Resilience and Maintainability Implications

• inferred — Identity refresh is not an atomic transition: overlapping asynchronous authentication reads are not cancelled, and user and claims perform additional reads. This machinery predates the PR. The added trigger warrants timing validation, but source inspection alone does not establish stale identity restoration or a newly reachable authorization bypass.

Hardening Proposals

• proposed — Validate delayed, repeated and overlapping expiry/recovery responses across authentication, user and claims before relying on token-request completion as proof that identity state has cleared.

Make the example compatible with the supported Angular versions.

The package supports Angular 13 and later, but @if requires Angular 17. Applications on Angular 13–16 cannot compile this example. Use *ngIf and import NgIf, or label the example as Angular 17+.
