mcp-data-platform-v0.13.0

Unified HTTP Transport

• Unified HTTP server serves both SSE (/sse, /message) and Streamable HTTP (/) transports from a single entry point
• Added StreamableConfig (session_timeout, stateless) to ServerConfig with YAML support and sensible defaults
• Added token bridging in MCP middleware to extract auth tokens from Streamable HTTP RequestExtra headers
• Added shared token context key between pkg/auth and pkg/middleware for cross-package interoperability
• Updated CORS headers for Streamable HTTP protocol requirements (Mcp-Session-Id, DELETE method)
• Renamed transport flag from sse to http (backward compatible)

Test Quality Remediation

• Removed 20 tautological struct-readback tests that tested Go compiler behavior rather than application logic
• Moved phantom newAuditStoreAdapterWithStore function from production code to test file
• Added 10 platform unit tests covering nil config handling, default timeouts, noop authenticator fallback, signing key boundaries, and close-with-nil-store
• Added 4 middleware chain integration tests using real mcp.Server + AddReceivingMiddleware + in-memory transport:
  • Semantic enrichment injects DataHub context into Trino responses
  • Query context injection adds Trino availability to DataHub search results
  • Default-deny persona blocks unauthorized tool calls (fail-closed)
  • Full-stack test validates all middleware layers execute in correct order
• Strengthened security-critical OAuth tests: token rotation proof, auth code entropy check, ExpiresIn validation, AccessToken != RefreshToken
• Strengthened audit event test to verify all 12 fields survive JSON round-trip

Tooling

• Added make dead-code target for unreachable function analysis
• Added make mutate target for mutation testing via gremlins
• Updated make verify to include dead code analysis
• Added AI Verification Requirements section to CLAUDE.md

Documentation

• Fixed all stale SSE-as-transport references across README, CLAUDE.md, and docs
• Added server.streamable config section to configuration reference
• Replaced manually maintained changelog with link to GitHub Releases
• Updated llms.txt and llms-full.txt for transport rename and streamable config
