…uages Add comprehensive OAuth authentication documentation to all four API client libraries (Go, Java, Python, TypeScript). Each includes: - Prerequisites and admin configuration links - Required headers table (Authorization, X-Glean-Auth-Type) - Complete authorization code flow example using idiomatic libraries - Token refresh tips for production use 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Address PR review feedback:
- TypeScript: Add PKCE (code_challenge, code_verifier) and state
verification using openid-client v6 correct API
- Java: Fix Spring Security YAML structure with proper named
registration/provider ("glean") and authorization-grant-type
- Go: Add cryptographic state generation and validation to prevent
CSRF attacks (was using hardcoded "state")

3/5 (strong opinion: non-blocking)
This should include offline_access to showcase getting a refresh token

4/5 (serious issue: blocking)
Have we validated this code works? We're OAuth 2.1 so state is optional and not even recommended but PKCE is required.
That we're generating a state suggests we might be not generating a PKCE challenge.
- Go: Use correct Search.Query() with components.SearchRequest, add PKCE with oauth2.GenerateVerifier/S256ChallengeOption/VerifierOption - Java: Add Spring Security PKCE config, use correct search().query() API - Python: Add PKCE via code_challenge_method='S256', use models.SearchRequest - TypeScript: Use correct search.query() API (not search.search()) All examples now use real SDK APIs verified from GitHub READMEs and include proper PKCE implementation for secure OAuth flows. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
