- transport.ts: update the SSE-branch comment to say the default path uses
fetchWithOptionalAuthIntercept (proxy-aware baseFetch + optional auth-challenge
intercept), not the bare proxy-aware baseFetch.
- clients/cli/README.md: fix the §5 mid-session validation link to use the
../../specification/ prefix like the sibling links in the same sentence
(previously resolved to a nonexistent clients/cli/ path).
Both flagged by the @claude review of PR #1601; comment/doc-only, no runtime change.

Address the TypeScript-safety review items on the mid-session auth work:
- oauthManager: replace the unguarded `this.oauthConfig.storage!` assertions on
the EMA re-mint/persist paths with a `requireStorage()` helper that throws a
clear error; in `getOAuthState` reuse the already-narrowed local `storage`.
- cli: `parseRunnerOAuthCallbackUrl` always returns a config, so make
`callMethod`'s `callbackUrlConfig` (and the always-passed `cliAuthOverrides`)
required instead of asserting them non-null at three call sites.
- test-servers/resolve-config: drop the `as unknown as T` double cast; collect
into a base-shaped array and do a single honest downcast at the return.
No behavior change; validate + coverage green.

`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

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}

Extends the header redaction from #1585. Before a fetch entry reaches any
sink, mask known-sensitive credentials in the request/response bodies and
the URL query string, in addition to headers:
- redactBody(): form-urlencoded + JSON bodies, recursive over nested
objects/arrays, best-effort (never throws), values-only.
- redactUrlQuery(): masks sensitive query params, preserves path,
non-sensitive params, and any fragment.
- Sensitive fields: client_secret, code, refresh_token, access_token,
id_token, code_verifier, client_assertion, assertion, password, token
(case-insensitive), reusing the [REDACTED] sentinel.
Applied to the request success + error entries and the async response-body
callback. Live outbound requests are byte-identical — only the logged copy
is redacted.

The "cancels a pending debounce timer when the input is re-focused" test
passed trivially after the delay:null change: synchronous typing meant the
assertion ran at t≈0, before the 300ms debounce could ever fire, so it
passed whether or not handleFocus's clearTimeout worked.
Rewrote it with fake timers so the debounce window elapses deterministically
(advance the clock by 400ms directly). The interaction is driven with
fireEvent rather than userEvent because userEvent's async internals deadlock
under vitest fake timers with the Mantine/happy-dom stack. Verified
load-bearing: removing the clearTimeout in handleFocus makes it fail
(expected 1 to be 0), and it passes once restored.
Also tightened the sibling-context comment (with delay:null the sibling is
reliably "es"); the tolerant /^es?$/ regex is left as-is.

Root-cause and deterministically fix the recurring 5s-timeout flakes that
surfaced under v8-instrumented, concurrent load. All fixes are test-only; no
product source changed. No test was skipped or disabled, and the per-file
coverage gate (>=90 on all four dims) still holds.
Common root cause across the modal/form/screen suites: userEvent.setup()
schedules a real setTimeout between keystrokes. Under CPU contention those
yields balloon, so multi-field interactions blew past the 5s per-test
timeout. Fix: userEvent.setup({ delay: null }) removes the per-keystroke
real-timer dependence (typing dispatches synchronously), making the suites
load-independent.
Per file:
- ServerConfigModal / ServerImportConfigModal / ServerImportJsonModal /
ResourcesScreen / InspectorView: userEvent.setup({ delay: null }).
- PromptArgumentsForm (completions): replaced wall-clock sleeps sized just
past the 300ms completion debounce (await setTimeout(400)) — which race
the debounce timer under load — with awaited conditions (findBy/waitFor)
on the real rendered outcome, plus delay:null. Negative assertions now
lean on the component's synchronous state/timer teardown instead of a
timed window, so they are deterministic regardless of machine speed.
- inspectorClient integration "tracks stderr logs": the child's stderr is
piped out-of-band from the tool's JSON-RPC response, so reading the log
synchronously after callTool raced the stderr chunk. Wrapped the assertion
in vi.waitFor so it polls until the line lands.
Verified: web validate + 6x test:coverage (4 sequential + 2 concurrent
under load) + standalone test:integration, all green (229 files / 3237
tests per coverage run; 799 integration tests), zero intermittent failures.

Round-2 @claude review of #1592 caught a seventh member of the clear
family that the first pass missed: clearClientInformation still wrote to
the store synchronously, carrying the same pre-hydration clobber risk the
clearAfterHydration helper was written for (a clear before hydration lands
persists a near-empty blob, overwriting the whole on-disk oauth.json).
Wrap its mutation the same way and add a clear-before-hydration test
proving a sibling token (and thus every other server's blob) survives.

Address round-1 @claude review of #1592:
- OAuthStorageBase.clear* no longer mutate the pre-hydration (empty) store —
a clear issued before hydration is deferred until it lands, so it merges
onto the real persisted state instead of (a) being resurrected by the late
rehydrate merge or (b) persisting a near-empty blob that clobbers every
other server's on-disk credential. Already-hydrated clears stay synchronous.
- store.setServerState migrates a pre-normalization raw-key blob onto the
canonical key on first partial write (was: shadowed it with a fresh
canonical entry, orphaning the raw blob's other fields). clearServerState
now also drops the raw-key orphan.
- Document the keepalive 64KB combined-body ceiling on the remote-storage
write, the getRemoteOAuthStorage memo key intentionally omitting fetchFn,
and the real ordering invariant behind the sync getScope.
- Tests for the clear-before-hydration and raw-key-migration paths.

- Document the intentional asymmetry between a present-but-malformed `state`

error redirects that omit `state`.
- Make the "valid state is not rejected" test assert the specific downstream

Migrate the web client's OAuth storage from BrowserOAuthStorage
(sessionStorage) to RemoteOAuthStorage, which POSTs through the backend's
/api/storage/oauth route to ~/.mcp-inspector/storage/oauth.json (mode 0600).
A credential obtained in the browser is now the same blob the TUI/CLI read
on the same host, giving web ⇄ TUI ⇄ CLI parity (Wave 1 of #1579).
Core (shared with TUI/CLI):
- OAuthStorageBase now drives a single async hydration (`ready()`,
`getHydrationError()`); every post-redirect read (getClientInformation,
getTokens, getCodeVerifier, getServerMetadata, getIdpSession) and every
save awaits it so a late hydration merge cannot clobber a fresh write.
getCodeVerifier/getServerMetadata become async; the store is created with
skipHydration:true so there is no auto-hydration to race the explicit one.
- store.ts adds normalizeServerUrl so a token saved under
https://Example.com/mcp is found when the CLI asks for
https://example.com/mcp/; getServerState falls back to the raw key.
- remote-storage adapter POSTs with keepalive so the write survives the
OAuth authorize redirect, surfaces swallowed persist failures, and gives
richer read/write error messages.
- generateOAuthState throws instead of silently degrading to Math.random.
- NodeOAuthStorage honors MCP_INSPECTOR_OAUTH_STATE_PATH for isolated
fixtures. Provider codeVerifier()/getServerMetadata() + the EMA idpOidc and
connection-state readers await the now-async storage.
Web:
- environmentFactory + a new shared lib/remoteOAuthStorage accessor
(memoized per {baseUrl, authToken}) wire RemoteOAuthStorage into the
connection path, the EMA IdP hook, and the per-server "clear OAuth" action
so all three share one in-memory view of oauth.json.
Tests: async-hydration + normalizeServerUrl suite, keepalive/error-path
coverage, and the sync→async migration across existing storage/provider/EMA
tests. Web validate + coverage gate + integration suite green; CLI/TUI/
launcher validate green.

Add a pure, DOM-free CSP-builder library at
clients/web/src/lib/sandbox-csp.ts that validates app-supplied
`_meta.ui.csp` requests, filters them to safe sources, builds the
locked-down Content-Security-Policy string, and wraps untrusted widget
HTML in a fixed host shell whose first <head> child is the CSP meta.
- SAFE_CSP_SOURCE: strict regex that rejects directive/attribute
breakouts (`;`, `"`, `<`, `>`, whitespace).
- approveCspSources(): drops unsafe entries (with a warning) and omits
empty keys; echoes back only what the host will enforce.
- buildSandboxCspPolicy(): `default-src 'none'` catch-all, `form-action
'none'`, source-allowlist filtering, `'unsafe-inline'` for the app's
own inline script/style.
- escapeHtmlAttr() / wrapSandboxedHtml(): defense-in-depth so untrusted
bytes never precede the applied policy.

* feat(web): add View Source toggle to resource preview (closes#1552)
Markdown, CSV, and HTML resources render in a way that hides the
underlying text (react-markdown, the CSV table, the sandboxed HTML
iframe). Add a "View Source" button to the resource preview footer, left
of Refresh and styled to match it, that swaps the rendered preview for
the raw resource text. In source mode the button reads "View Rendered".
- Only shown for markdown/csv/html (other kinds already show their text,
or have no meaningful text source).
- Source mode forces ContentViewer through its plain-text renderer; the
displayed MIME label keeps the resource's real type.
- The toggle resets to the rendered view when the previewed resource
changes (React's adjust-state-during-render pattern — no effect).
Tests cover the toggle round-trip, per-kind visibility, and the reset;
a Storybook play function exercises rendered → source → rendered.

* refactor(web): address View Source review nits (#1553)
- Per-item source gating: in source mode only source-toggleable items
switch to plain text, so a mixed multi-part resource doesn't force an

- Share a FooterButton constant between Refresh and the View Source
toggle so the two stay visually identical (per the subcomponent
guidance — both had the same two inline props).
- Add aria-pressed to the toggle so assistive tech gets explicit on/off
state beyond the label flip.
Tests added for the aria-pressed state and the mixed multi-part case.
