Summary:

• render anyOf, oneOf, and allOf response schemas as expandable branches in the HTTP reference
• infer filesystem route contracts through HandlerFunction annotations and Response.json payloads
• add documentationOutput for programmatic HTTP contracts without runtime validation

Validation completed: typecheck, build, 123 docs tests, 13 focused tests, 1536 unit tests, smoke, security audit, boundaries. Integration suite is still running locally.

The line-limit check is already red on origin/main because the script rejects files above the existing baseline. No package version or release is included; publishing remains a maintainer action.
