Chris CoutinhoandClaude e81c2ad33d docs: Update upstream OAuth status with completed oidc app PRs [skip ci] 
Update oauth-upstream-status.md to clarify patch requirements and document
completed upstream work:

**Clarifications:**
- CORSMiddleware patch is for Nextcloud core server (not user_oidc app)
- Root cause: CORS middleware logs out sessions without CSRF tokens
- Solution: Allow Bearer tokens to bypass CORS/CSRF checks
- Updated all references with actual PR number: nextcloud/server#55878

**Completed oidc app PRs (now documented):**
- ✅ H2CK/oidc#586: User consent management (v1.11.0+)
- ✅ H2CK/oidc#585: JWT tokens, introspection, scope validation (v1.10.0+)
- ✅ H2CK/oidc#584: PKCE support (RFC 7636) (v1.10.0+)

**Updated sections:**
- "What Works Without Patches" - Added JWT, scopes, consent features
- "Upstream PRs Status" - Added completed PRs table
- "Monitoring Upstream Progress" - Focus on remaining work
- Last updated date: 2025-11-02

All OAuth features except app-specific APIs now work out of the box
with oidc app v1.10.0+. Only CORSMiddleware patch remains pending.

Chris CoutinhoandClaude 849c67c32a fix: Complete Keycloak external IdP integration with all tests passing 
This commit completes the Keycloak external IdP integration for the MCP
server, implementing ADR-002 Tier 2 (External Identity Provider) with
full Bearer token authentication support.

Key Changes:
1. **Keycloak backchannel-dynamic configuration**
   - Added --hostname-strict=false and --hostname-backchannel-dynamic=true
   - Allows external issuer (localhost:8888) with internal endpoints (keycloak:8080)
   - Solves Docker networking issue where containers can't reach localhost

2. **CORSMiddleware Bearer token patch**
   - Created app-hooks/patches/cors-bearer-token.patch from upstream commit 8fb5e77db82
   - Allows Bearer tokens to bypass CORS/CSRF checks (stateless authentication)
   - Applied via post-installation hook 20-apply-cors-bearer-token-patch.sh
   - Enables app-specific APIs (Notes, Calendar, etc.) to work with Bearer tokens

3. **Patch organization**
   - Moved patches to app-hooks/patches/ directory
   - Updated docker-compose.yml to mount entire app-hooks directory
   - Consolidated patch management for better maintainability

4. **Test improvements**
   - All 11 Keycloak integration tests passing
   - Tests validate OAuth token acquisition, MCP connectivity, token validation,
     tool execution, token persistence, user provisioning, scope filtering,
     and error handling

Architecture:
- Keycloak acts as external OAuth/OIDC identity provider
- MCP server uses Keycloak tokens to access Nextcloud APIs
- Nextcloud user_oidc app validates Bearer tokens from Keycloak
- No admin credentials needed - all API access uses user's OAuth tokens

Cache Note:
- Discovery and JWKS caches must be cleared when switching Keycloak configurations
- Use: docker compose exec redis redis-cli DEL "<cache-key>"
- Or: docker compose exec app php occ user_oidc:provider keycloak --clientid nextcloud

- Validates external IdP integration pattern
- Demonstrates offline_access with refresh tokens (Tier 1 & 2)
