- Added optional FetchImpl fields to compaction, proxy, AI, coding-agent, and mnemopi options.
- Threaded injected fetch implementations through OAuth, discovery, and search/LLM request flows.
- Removed exported hookFetch utility and its package entrypoint from utils.
- Replaced global-fetch test monkeypatching with per-test FetchImpl mocks across test suites.
- Extended `buildWellKnownUrls` and `#resolveRegistrationEndpoint` to try `/.well-known//` as a third candidate after origin-root and path-prefixed forms.
- Fixed single-segment path handling so `/my-service` is treated as the gateway prefix rather than dropped.
- Fixed missing `await` on `#tryWellKnownForRegistration` that caused path-prefixed fallback to return an unresolved Promise.
- Added tests for single-segment prefix discovery and RFC 8414 path-ful issuer fallback.
- Extract resource_metadata URL from WWW-Authenticate and follow RFC 9728 chain
- Add buildWellKnownUrls with path-prefixed well-known fallback for gateways
- Fix resolveRegistrationEndpoint to try path-prefixed well-known (was missing await)
- Support relative Mcp-Auth-Server URL resolution against server URL
- Pass resourceMetadataUrl through all discoverOAuthEndpoints call sites
- Add comprehensive tests for path-prefixed, resource_metadata, and relative URL flows
- Extracted fetch mocking logic into reusable `hookFetch()` utility function with middleware-style handler pattern.
- Replaced manual `globalThis.fetch` assignment and restoration across 10 test files with `hookFetch()` calls using `using` statement for automatic cleanup.
- Implemented Disposable pattern with Symbol.dispose for fetch hook resource management, eliminating try-finally blocks.
- Exported `hookFetch` from utils public API to enable consistent fetch mocking across packages.
- Added `authServerUrl` field to `AuthDetectionResult` to capture MCP OAuth server metadata.
- Added `extractMcpAuthServerUrl()` function to parse and validate `Mcp-Auth-Server` header URLs from OAuth errors.
- Enhanced `discoverOAuthEndpoints()` to accept optional `authServerUrl` parameter and query `/.well-known/oauth-protected-resource` endpoint.
- Improved OAuth metadata extraction to handle multiple `clientId` field variations (`clientId`, `default_client_id`, `public_client_id`).
- Extracted metadata parsing logic into reusable `findEndpoints()` helper function supporting multiple OAuth metadata formats.
- Added comprehensive test coverage for OAuth endpoint discovery, header parsing, and error validation.
