The network tracker wrapped the auth-challenge interceptor, so a 401/403
never reached it as a response: the interceptor cancelled the body and
threw, and the tracker logged only the thrown error. NetworkEntry renders
its response section only when a status is present, so the body — and the
WWW-Authenticate resource_metadata and scope — were never shown.
Move the tracker below the interceptor so it records the real response and
clones its body before the interceptor cancels it, and stop awaiting that
cancel: with the tracker's clone as the other tee branch, the cancel settles
only once the clone reads to the end, which would hang on an unending body.

The challenge-driven plumbing did not reach the default CLI/TUI flow. With
no stored token in the legacy era, InspectorClient deliberately builds the
transport with no authProvider (so the SDK cannot open a browser before the
callback server is listening), which also leaves challenge interception off;
the 401 then surfaces as the SDK's headerless UnauthorizedError and the
runner calls authenticate() with no challenge in hand. So a server serving
metadata only at the advertised path still failed there — including for the
legacy showcase the README instructs.
Add a passive counterpart to the challenge interceptor: an observer fetch
that reports every 401/403 without touching control flow or the body. The
OAuthManager records the advertised URL from it and uses it in
authenticate() and its CIMD pre-registration. Latest-wins, including
clearing when a later challenge advertises none.
Also: the fixture helper dropped an explicitly supplied empty
resourceMetadataPath by truthiness, bypassing validation and silently
reverting to the well-known route.
Covered by a direct-client integration test that drives connect ->
authenticate() against the real server and asserts the advertised path was
requested and the well-known one never was; verified failing without the
fix.

The mid-session auth work passed `validate`/CI but failed the local-only
`npm run test:coverage` per-file gate (≥90% lines/statements/functions/
branches) on 12 files. Add targeted unit/integration tests so every changed
file clears the gate; annotate provably-dead defensive branches with justified
`/* v8 ignore */` comments rather than relaxing the gate.
Files brought to ≥90 on all four dimensions:
- core/auth: mcpAuth, oauthUx, utils, challenge, node/runner-interactive-oauth
- core/mcp: oauthManager, inspectorClient, node/authChallengeFetch,
remote/remoteClientTransport, remote/node/{remote-session,server}
- clients/web/src/utils: oauthResume, browserTabVisibility
`npm run test:coverage` now passes (3575 tests, 0 threshold failures);
`npm run validate` green across all four clients.
