chore: replace main's tree with v2 by cliffhall · Pull Request #1830 · modelcontextprotocol/inspector

cliffhall · 2026-07-28T03:11:48Z

Phase 4 of the v2 go-live runbook (#1804 §5). main becomes the v2 tree.

⚠️ Do not squash-merge. This must land as a merge commit — squashing collapses the two parents and defeats the entire point (see below).

What this is

A true merge recording v2/main as a second parent, not a reset:

parent ac3c1a12   (main @ 1.0.0)
parent 4d30d1cd   (v2/main)

So main's history survives, no force-push is needed, branch protection on the default branch stays on, and main becomes a genuine superset — meaning v2/main can afterwards be fast-forwarded to main or retired cleanly.

git diff HEAD origin/v2/main is empty: the tree is byte-identical to v2/main, 1216 files.

One correction to the runbook

§5's command fails as written:

fatal: refusing to merge unrelated histories

main and v2/main have genuinely unrelated histories — different root commits (996f02c7 vs 3b583e1f), no merge base at all. --allow-unrelated-histories is required:

git merge --no-commit -s ours --allow-unrelated-histories origin/v2/main
git rm -rf . && git checkout origin/v2/main -- .
git commit

This follows from something AGENTS.md already notes — v1.5/main was never an ancestor of v2/main — but §5 didn't account for it.

Open PRs were moved first

All 125 open PRs targeting main were re-pointed at v1/main before this, so none are stranded against a tree that no longer exists. v1/main strictly descends from main, so their merge bases and diffs are unchanged — spot-checked that #1732 (the DNS-rebinding TOCTOU fix), #1696 and #1519 all still report MERGEABLE. Triage remains #1819's job.

Note it was 125, not ~30 — gh pr list defaults to a limit of 30, which badly understated the backlog. Relevant to #1819's rate-limit planning.

Verification

git diff HEAD origin/v2/main — empty
Two parents present, old main (ac3c1a12) is an ancestor of the merge
No client/ server/ cli/ paths tracked in the commit (the dirs remaining on my disk are untracked node_modules/build residue)
Root package.json version reads 2.0.0

After merge

Closes #N starts auto-closing, since PRs into main now target the default branch — the manual close-and-move-to-Done ritual can stop (#1821).

…d V1.5 board (#1555) * docs(AGENTS): document board membership + status workflow; drop closed V1.5 board (closes #1554) The Issue-driven Work Style section described board interaction in prose but only gave concrete gh commands for the version label, so agents labeled issues/PRs without adding them to board #28 or setting a Status. - Add explicit gh recipes for `project item-add` + `project item-edit`, including the V2 board's project/field/Status-option IDs. - Correct Status names to the real board values (In progress / In review, plus Backlog / Building / Done). - State that a v2 item isn't "created" until labeled AND on the board with a Status set. - Remove the closed V1.5 board (project 39) and its base-branch/label references. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(AGENTS): require real issues (no drafts) and assign issues to their creator Per maintainer guidance: every board item must be an actual GitHub issue, not a draft card, and each issue must be assigned to the user it is created for. Replaces the draft-items-vs-issues bullet. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(AGENTS): clarify PR-to-issue linking limits on non-default branch Closing keywords (Closes #N) only auto-link and auto-close for PRs that target the repo's default branch. v2 PRs target v2/main, so the keyword is only a cross-reference there. Document that: - the PR body's first line must still be `Closes #<ISSUE_NUMBER>`, - there is no gh flag to manually link (no `gh pr edit --add-issue`), - on merge, the issue must be closed manually and its board item moved to Done, since auto-close won't fire on v2/main.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(AGENTS): mark v1.5/main as a frozen reference branch (do not delete) v1.5/main is merged and takes no new work, but the branch is kept as a reference point (e.g. to track down a regression introduced by the merge into v2/main). Note that it should not be deleted.

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. Re-implements the sandbox-csp portion of PR #1510 (Wave 1 of #1579) as a standalone library; wiring into the app bridge is a follow-up issue. Adds full unit tests (100% lines/statements/functions/branches) and lists the file in the web coverage `include` so it is gated (the untested legacy src/lib siblings stay out until they get tests).

…oses #1562) generateOAuthState() now throws when crypto.getRandomValues is unavailable instead of silently degrading to a non-cryptographic Math.random() fallback — OAuth state is a CSRF token and must be unpredictable.

…ge parity) (closes #1548) 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.

Address @claude review of #1583: - statusOf() now only treats a numeric `.code` as an HTTP status when it is in the 100-599 range, so an MCP SDK McpError JSON-RPC code (e.g. -32601 MethodNotFound) is no longer leaked into the envelope `status` or misclassified as AUTH_REQUIRED (it falls back to USAGE). - causeOf() now carries a depth cap (MAX_CAUSE_DEPTH) so a cyclic/ self-referential `error.cause` chain terminates instead of recursing infinitely. - Add tests for both: a -32601 McpError-shaped error (status undefined, exit USAGE) and a self-referential cause chain (finite string).

…asymmetry, tighten test - Soften the OAuth-callback-rejected toast: the shape guard is defense-in-depth, not full CSRF prevention (PKCE remains primary), so the message no longer overstates ("rejecting to prevent a cross-site request" -> "did not originate from this session"). - Document the intentional asymmetry between a present-but-malformed `state` (rejected) and a wholly absent `state` (accepted, matched via OAUTH_PENDING_SERVER_KEY) — rejecting the null case would mask real provider error redirects that omit `state`. - Make the "valid state is not rejected" test assert the specific downstream "could not be matched" toast (seeding OAUTH_PENDING_SERVER_KEY) instead of an indirect "some toast fired" check.

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.

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).

…1596) 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.

…ound 1) 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.

* ci: add headless-browser boot smoke for the web client (#1615) smoke:web only asserts GET / serves the SPA HTML with the injected token; it never runs the React app, so a Node built-in reaching the browser bundle (which crashes the app to a blank page at runtime, e.g. #1612) slips through. Add smoke:web:browser, which boots the same prod --web server and runs the bundle in headless Chromium (Playwright, already a clients/web devDependency), asserting the app renders its first frame (the "Add Servers" control) with no uncaught page errors — in particular no `Module "node:*" has been externalized`. This catches "Node code reached the browser bundle" as a class, not one import at a time.

It only passed locally because an ancestor node_modules happened to carry playwright; CI has none, so it failed with "Cannot find package 'playwright'". Resolve it explicitly from clients/web via createRequire, independent of cwd and ancestor dirs.

Keeps polling on non-ok (a warming server may answer 503). - Add a child 'error' handler so a spawn-level failure surfaces as the smoke's FAILED line instead of an uncaught raw stack; readiness and the child-exit race both report it. - Drop the unused isExited/exitCode/child exports from the helper API. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * ci: reframe browser smoke around uncaught pageerror; fix stop() edge Third-review findings. 1. The `Module "…" has been externalized` string can't fire against a Vite 8 *prod* bundle — verified end-to-end against the installed vite@8.0.0: a node: import reaching the browser graph is a BUILD-time warning, and the shipped stub is a silent `module.exports = {}`. The real #1612 manifestation is the first *call* into that empty stub throwing a TypeError at module init (confirmed: injecting a used `node:fs` import fails the smoke with "readFileSync is not a function"; an unused one ships {} and is harmless). So the signature machinery was dead against the bundle it runs on — dropped it. The smoke now asserts exactly what it verifies: the prod bundle boots and paints with no uncaught page error. Reworded the script header, the AGENTS.md bullet, and the README row to match. Console errors stay diagnostic-only. 2. The helper's child 'error' handler set `exited = true`, but Node emits 'error' for a failed kill/send too (child still alive) — so `stop()` (guarded on `exited`) would skip the SIGTERM and orphan the launcher on the port. Track the error separately (`childError`); `bootFailed()` = exited || childError, while `stop()` still SIGTERMs a live child. Docs: fixed the stale AGENTS.md claim that `cd clients/web` makes `import("playwright")` resolve (createRequire does, cwd-independently; the cd is only for `npx playwright install`), and noted the shared scripts/lib/prod-web-server.mjs helper on both smoke bullets.

The async twin of the #1612 shape — the same empty-stub TypeError reached through an await/.then(), or a failed dynamic import (this app lazy-loads chunks) — lands on the console channel as `Uncaught (in promise) …` / `Failed to fetch dynamically imported module`, which were diagnostic-only, so the smoke would have passed. Hard-fail console errors matching /^Uncaught\b|Failed to fetch dynamically imported module/; every other console error stays a printed non-fatal note. The prefixes are unambiguous (a font/CDN miss reads "Failed to load resource: net::ERR_…"; React warnings never start with "Uncaught"), so this can't reintroduce the flake the earlier round fixed. Verified: an unhandled rejection at module init now fails the smoke where it previously wouldn't. Also prod-scope the AGENTS.md note that the "externalized" string isn't a runtime message (under `npm run dev` Vite's stub is a Proxy that console.warns it), and document both the sync and async failure signals.

The OK console line and the README smoke row still said "page error"; match the two-channel wording already in the AGENTS.md bullet.

A failure there means the package isn't resolvable from clients/web, so the actionable fix is `npm install` at the repo root (the postinstall cascade installs clients/web's devDependencies). The chromium.launch() catch keeps its --with-deps advice (correct for the missing-system-libraries case).

…1770) * refactor(web): consolidate the three GET /api/config hooks into one (#1643) useSandboxUrl, useServerListWritable, and useInspectorVersion each fetched the same static /api/config payload separately and read one field from it — three requests on load for one payload. Replace them with a single useInitialConfig hook that fetches once and exposes { version, sandboxUrl, writable, loading } with the same tolerant parsing/defaults (writable defaults true; version/sandboxUrl undefined when absent; unmount-safe). - Add core/react/useInitialConfig.ts; wire App.tsx to it. - Remove the three former single-field hooks and their tests. - Fold the fetch-branch matrix into one useInitialConfig test.

…1771) Codebase-wide sweep bringing the web client into strict compliance with the AGENTS.md TypeScript and Mantine/React conventions: ~170 inline 2+-static-prop elements extracted to named .withProps() constants across ~77 files, the AGENTS.md rule wording tightened to match (static-prop boundary + Accordion/Transition/data-*/Box exemptions), a real ScreenStage Box->Flex layout regression fixed (direction: column) with a Storybook regression guard, and an App.tsx double-cast tightened. Closes #1762.

…erInfo (#1773) A modern-era server/discover makes serverInfo optional (SHOULD, not MUST); a conforming modern server that omits it left initializeResult undefined, collapsing the entire connected header + tab bar so the server was uninspectable. Gate initializeResult on connectionStatus alone with a catalog-name fallback, and thread a serverInfoReported flag so the Connection Info modal reports the omission truthfully instead of presenting the inferred name as server-sent. Closes #1772.

…ty reported serverInfo name (#1774) (#1775) * fix(web): degrade the connected header to the catalog name for an empty reported serverInfo name (#1774) A server that reports serverInfo with an empty name string (an empty-but-present name) left ViewHeader rendering a nameless title. App's `??` fallback only fires when the whole serverInfo object is absent (the #1772 modern-omitted case), so a reported `{ name: "" }` slipped through with `serverInfo.name === ""`. Resolve the header's display name in InspectorView: fall back to the active server's catalog name when the reported name is blank. This is a display-only fallback — the Connection Info modal stays faithful to the raw report because it reads App's untouched `initializeResult` + `serverInfoReported`, so `serverInfoReported` keeps meaning "the server sent a serverInfo object" (a reported-but-empty name still reads as "—" in the modal, and any reported version stays intact — driving the flag off name emptiness would wrongly mask the version).

The header now degrades a whitespace-only reported name; the modal had the same gap — `serverInfo.name || "—"` treats " " as truthy and renders a visually blank row, the exact outcome the `||` exists to prevent. Trim both the name and version rows before the fallback so a blank-but-present value reads as "—". Uses optional chaining (`?.trim()`) to preserve the prior tolerance of a non-conforming runtime-absent field (the type is non-null, but a server can omit it — covered by the existing "version missing" test). Stays faithful: the fallback is still "—", never a borrowed catalog name. Applied the same `?.` hardening to the header's resolveHeaderServerInfo guard.

Commit 2f508ff added `serverInfo.name?.trim()` in both ConnectionInfoContent and resolveHeaderServerInfo, but only the version `?.` short-circuit was exercised (by the pre-existing "version missing" test) — the symmetric name `?.` was uncovered. Add two tests passing a serverInfo that omits `name` (`{ version: "1.0.0" } as never`): the modal Name row reads "—", and the header degrades to the catalog name. Pins the documented tolerance and makes the two new branches explicit rather than relying on gate headroom.

…1769) (#1777) * build(web): fail vite build on a browser-externalized Node built-in (#1769) Vite 8 (rolldown) externalizes a node:* / Node built-in that reaches the browser graph with a warning and ships a `module.exports = {}` stub — the build still succeeds, shipping a broken bundle. The runtime browser smoke (smoke:web:browser, #1615) only catches the subset where that stub is *called* at module init; a stub imported but never called ships silently and nothing gates it. Add a Vite build plugin that turns that specific browser-externalization warning into a hard `vite build` error, moving detection upstream into `npm run build` / `validate` and additionally catching the never-called case the runtime smoke can't see. - clients/web/server/browser-externalized-builtin-gate.ts: Vite-agnostic detection + error + per-build state machine (unit-tested to the ≥90 gate). - vite.config.ts: thin Vite wiring. A throw inside rolldown's onLog is swallowed (the one hook where it doesn't abort — verified against vite@8.0.0), so the gate records the warning in onLog and re-throws in buildEnd. Scoped to `vite build` (apply: 'build'); the Node runner build (tsup) is unaffected. - scripts/verify-build-gate.mjs + verify:build-gate (in npm run ci and the GitHub workflow): runs a real build with a node:fs probe and asserts it fails via the gate — the only check that catches the warning phrasing drifting in a future Vite bump and silently disabling the message-keyed gate. There is no stable log `code` on the rolldown warning (only message + plugin), so the gate keys off the documented message phrasing; the drift guard above is what keeps that safe across Vite versions. smoke:web:browser stays as the runtime backstop.

Makes the docblock true. - buildEnd(error) now only asserts on the success path — rolldown also calls buildEnd(error) when the build already failed for another reason, and throwing then would mask that real error with the #1769 message. - verify-build-gate.mjs: drop the shell `rm -rf` cache-clear entirely (verified the gate fires reliably without it — the earlier "caching" symptom was the onLog-swallow behavior, not a stale cache); add a result.error spawn-failure check so a missing `npx` isn't misdiagnosed as "not via the gate"; add SIGINT/SIGTERM handlers so an interrupt during the multi-minute build still restores the mutated entry; add a progress log before the spawn. - Match the double-quote style of the sibling server/ files. - Docs: list browser-externalized-builtin-gate.ts in the AGENTS.md server/ block and the clients/web/README server/ list (with why a build helper lives under server/), and add verify-build-gate to the root README scripts/ line.

Guard the entry read so a renamed main.tsx fails through fail() with an actionable message. On a botched restore, save the captured original to a sidecar .bak and point there instead of recommending `git checkout --`, which would discard uncommitted edits. - AGENTS.md: fix the muddled CI-steps sentence (GitHub CI runs the whole chain as separate steps, Storybook last) and note the applyToEnvironment client-only scoping in the gate prose.

The old message hard-coded "phrasing drifted", which misdirects for the config-regression class this script exists to catch. Added applyToEnvironment to the docblock's config-regression list too. - Bound the build with a 10-min spawnSync timeout (+ SIGKILL); a timeout sets result.error (ETIMEDOUT) and reports via the existing branch, instead of burning to the GitHub job's 360-min default with no output. - Guard the probe write so a read-only/EACCES checkout fails through fail() with an actionable message instead of escaping as a raw stack. - SIGTERM now exits 143 (was 130, which is SIGINT's code).

Without it, a stale KNOWN_PHRASE after a phrasing update would make the three-way diagnosis misreport a plugin-not-applying regression as a phrasing drift — the exact misdirection the diagnosis exists to avoid. - Make the .bak safety net reachable on the path that needs it most: restoreEntry now catches its own write failure and routes to a shared saveBackupAndFail helper, instead of letting the write escape the finally as a raw stack (which skipped the .bak fallback and left the probe injected in the entry). - Add the fourth "plugin isn't applying" cause to the diagnosis: a future Vite emitting the warning before the client env's buildStart reset clears it (same symptom as the other three). - Flag once, on the failing-check path, that clients/web/dist holds a probe build so a local debugger doesn't serve it unaware.

The issue number also appears in vite.config.ts comments, so a code frame from an unrelated build error there could otherwise make the check report OK with the gate dead — the one direction it must never get wrong (a false pass hiding a dead gate). - Drift guard now anchors on the BROWSER_EXTERNALIZED_BUILTIN_PHRASE assignment (regex) instead of a whole-file substring match, so the old wording lingering in a comment can't mask a changed constant; and its readFileSync of the gate module is guarded so a moved file fails through fail() actionably. - Extract PROBE_MODULE ("node:fs") used to build both the PROBE and the diagnosis check + messages, so changing the probe module can't silently misroute a phrasing-drift failure into "probe never reached the graph". - Comment the load-bearing diagnosis order (phrase before module-name).

Previously only KNOWN_PHRASE was guarded; the prefix is mirrored across the same TS/.mjs boundary for the same reason, so rewording the gate's thrown error would make a correctly-firing gate report "the build broke for another reason" (benign direction, but the same misdirection the other guards close). - Write the restore-failure .bak under the OS temp dir, not next to the entry: a sidecar inside src/ is untracked and a `git add -A` (likely while recovering) would sweep it into a commit. - Branch-(b) remediation now says update BOTH the gate constant AND KNOWN_PHRASE, so a phrasing-drift fix lands in one pass instead of tripping the drift guard on the next run. - Note next to BROWSER_EXTERNALIZED_BUILTIN_PHRASE that it must stay a single string literal (the script's drift guard anchors a regex on the assignment).

Uses mkdtempSync for a unique dir instead of a fixed tmp filename, so a pre-existing/foreign-owned /tmp file can't make the recovery message point at someone else's content. - Guard the restore-verification readFileSync too, routing a failure through saveBackupAndFail so the whole restore path is uniformly safe (a raw throw there would skip the backup net). - vite.config.ts: enforce: 'pre' on the gate plugin so it runs ahead of the normal-plugin group in the onLog chain — a plugin whose onLog returns false filters the log for later plugins, so trailing the array would let a future log-filtering plugin silently blind the gate.

Call restoreEntry() in that catch to roll the partial write back (falling through to the .bak net if the restore itself can't write), and correct the comment that claimed a write failure happens "before any mutation". Also widen the enforce:'pre' comment to note it orders ahead of Vite's core plugins too (harmless — the gate defines no resolve/load/transform).

On a read-only checkout nothing was ever written, yet the developer was told the restore failed and pointed at a /tmp backup of an untouched file. Roll back inline instead: attempt the restore without exiting, track whether it succeeded, then always report the PRIMARY write error, appending "restore from version control" only when the rollback didn't take.

Reworded the comment to not repeat the full lead (matching how the phrase pin avoids repeating its phrase); the literal now occurs exactly once, restoring the guard's meaning. Also make the probe-write recovery message factual instead of inferred: read the entry back and only warn "restore from version control" when it actually differs from the original. On a read-only checkout both writes fail at open, so the file is untouched and the old hedge needlessly implied damage.

…d modules (#1784) * refactor(web): sharpen src/lib vs src/utils rule and move misfiled modules (#1776) Codify the empirical rule the web client already followed loosely — utils = pure functions that compute; lib = things that instantiate, adapt, or touch the environment — in AGENTS.md and clients/web/README.md, and move the modules that sat on the wrong side of it. Moves (source + co-located test): - lib/sandbox-csp -> utils (pure CSP-string construction; type-only import) - utils/browserTabVisibility -> lib (registers visibilitychange listeners) - utils/oauthResume -> lib (reads/writes sessionStorage) - utils/clearServerOAuthState -> lib (drives live InspectorClient / OAuthStorage) Borderline audits (kept in place): pendingReauth (pure type declarations), deepLink / correlateTransportErrors / mcpNetworkHeaders / oauthUx / oauthFlow / oauthNetworkPhase (pure transforms / type-only core imports) stay in utils; downloadFile stays whole in lib (dominant side is DOM side effects). Also relocate the lone src/test/lib/downloadFile.test.ts straggler beside its source at src/lib/downloadFile.test.ts, and document the test-placement rule (side-by-side by default; src/test/ only for core/ tests, the integration project, and shared scaffolding). Pure move — no behavior change; no build/coverage config keys off the boundary.

Stale path references (fixed): update the four in-repo pointers left at pre-move paths — specification/v2_auth_mid_session.md (oauthResume, browserTabVisibility → lib/), and the two load-bearing sandbox security comments (sandbox_proxy.html, sandbox-controller.ts → src/utils/sandbox-csp). 2. lib/types/customHeaders (moved): it's pure (types + pure transforms), the rule's clearest counterexample. Moved lib/types/customHeaders.{ts,test.ts} → utils/ (no external importers; only its own test) and removed the undocumented lib/types/ subdir. Documented that utils/ is the home for pure shared domain types + their constructors — no separate types/ bucket. 3. One-way arrows (item 3): declare OAuthResumeAuthKind in utils/pendingReauth and re-export it from lib/oauthResume, so the only cross-directory arrow now points lib → utils. Codified that invariant in AGENTS.md. Wording nit: AGENTS.md + README now state diagnostic logging (console.warn/error) doesn't count as a side effect for the utils rule.

Stale paths (same class as round-1 item 1): the customHeaders move left three references to the deleted lib/types/customHeaders.ts path in specification/ (v2_ux_interfaces_phase_0_4_inventory.md, v2_ux_interfaces_plan.md ×2) — updated to utils/customHeaders.ts. 2. customHeaders anchor: note in AGENTS.md that its shape is staged for ServerSettingsForm (per v2_ux_interfaces_plan.md), so its zero-importer state reads as intentional rather than rot; kept as the no-types/-bucket illustration and led the anchor list with load-bearing modules. 3. Type-only-import clause: split the conflated clause — a type-only import (pendingReauth) and re-exporting core's pure functions/constants (oauthUx/oauthFlow) are distinct reasons to stay in utils; what makes a module lib is wrapping core's stateful runtime. Fixed in both AGENTS.md and the web README. Cosmetic: re-padded the v2_auth_mid_session.md table row to column width.

"no separate types/ bucket" overreached: clients/web/src/types/ does exist (navigation.ts + react-syntax-highlighter .d.ts ambient stubs wired via tsconfig.app.json paths). Scoped the claim in both AGENTS.md and the web README to "no types/ sub-bucket INSIDE lib/utils", and noted src/types/ is for ambient .d.ts stubs, not domain types. 2. README example list drifted from AGENTS.md's round-2 load-bearing anchors — realigned it (inspectorTabs/mcpNetworkHeaders, dropped the zero-importer customHeaders from the headline list). 3. Clarified v2_ux_interfaces_plan.md:185 so the v2 path reads as the copy's destination, not as the v1.5 source location. Follow-up filed as #1785 (board Todo): src/types/navigation.ts InspectorTab is dead and duplicates utils/inspectorTabs.ts — kept out of this pure-move PR.

Grammar (item 1): the round-4 #1785 clause read "superseding [#1785] will remove it" — a participle with no subject. Reworded to "the dead navigation.ts InspectorTab, which #1785 will remove". 2. Readability (item 2): the src/utils/ bullet had accreted into a single ~1,400-char blob across five review rounds. Promoted the carve-outs to scannable sub-bullets (Domain types / Diagnostic logging / Importing from core) and lifted the src/types/ note out to its own line, since it's a statement about a sibling directory, not about utils.

"no build/coverage glob" was factually wrong (should-fix): the web coverage include in clients/web/vite.config.ts DOES enumerate src/lib/** and src/utils/**. The conclusion (a move between them is coverage-neutral) survives, but the reason was wrong. Reworded both AGENTS.md and the web README to say nothing *enforces* the boundary — no path alias, and the include lists both dirs so a move is coverage-neutral — plus the important whitelist caveat: a module outside components/lib/utils/server falls out of the ≥90 gate entirely. 2. Removed a pre-existing duplicate glob in vite.config.ts (src/lib/**/*.{ts,tsx} appeared twice, lines 161 and 163). Inert (vitest de-dupes) but it sat three lines from the config the doc now describes. Nits: gave the README bullet the same round-5 sub-bullet restructure as AGENTS.md, and made its #1785 reference a real markdown link (bare #N doesn't autolink in rendered repo markdown). npm run ci green (config change re-verified through coverage + smokes + Storybook).

…eak 'window is not defined' (#1786) (#1793) * test(web): settle real-timer Transitions so the coverage gate can't leak 'window is not defined' (#1786) The web coverage gate was intermittently failing with an unhandled `ReferenceError: window is not defined` thrown from a Mantine `Transition` timer that fired after happy-dom tore down `window` (the #1760 class). The three `ViewHeader.test.tsx` tests that use `renderWithMantineTransitions` (real, env="default" timers) each drove their *primary* transition to completion, but the concurrent *enter* on a sibling cell leaves no unmount to `waitFor`, so its rAF→setTimeout chain could still be pending at teardown and fire post-teardown, failing an unrelated later file's run. Fix: after each such test, flush pending transition timers against the still-mounted tree via `settleTransitions()` (a wait longer than the 300ms header duration + rAF slack), so the settling setState targets a live tree and nothing is left to fire after cleanup unmounts. Also close the related nit: `renderWithMantine`/`renderWithMantineTransitions` now accept a `colorScheme` option, so `ViewHeader.test.tsx` no longer hand-rolls a bare `defaultColorScheme="dark"` MantineProvider (the #1760 anti-pattern). AGENTS.md documents both the option and the settle requirement. Closes #1786 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * test(web): address review — export settleTransitions, derive settle from HEADER_ANIM_MS, guard fake timers, correct comments Review feedback on PR #1793: 1. Derive the settle window from the real animation duration: export `HEADER_ANIM_MS` from ViewHeader.tsx and compute `TRANSITION_SETTLE_MS = HEADER_ANIM_MS + 200` in the test, so bumping the header duration can't silently make the settle insufficient (the invariant is now structural, not a comment). 2. Move `settleTransitions` into the shared `renderWithMantine.tsx` helper (exported, optional `ms` arg) next to `renderWithMantineTransitions`, since AGENTS.md points every future caller at it — shared test scaffolding belongs in src/test/, not a single test file. AGENTS.md now references the helper. 3. Guard `settleTransitions` against `vi.useFakeTimers()`: it awaits a real setTimeout, so under fake timers it would hang to the test timeout. Throw a clear message instead. 4. Correct the diagnosis comments: the hazard isn't a Mantine timer surviving unmount (its effect cleanup cancels timers) — it's the React state update Mantine's inner rAF schedules outside `act`, resolving post-teardown. Also fix the stale setup.ts matchMedia comment: the reduce-motion stub does not disable transitions (Mantine defaults respectReducedMotion=false); env="test" is the actual #1760 protection.

Justify 500ms generically — a typical few-hundred-ms transition plus rAF slack. - settleTransitions doc: stop asserting a single escape mechanism as fact. State what's observed (a post-teardown dispatchSetState throwing from resolveUpdatePriority, which runs synchronously inside dispatchSetState), what's known (useTransition has an unmount cleanup), and that the exact escape route isn't pinned down — the act-wrapped drain fixes it regardless. - setup.ts: happy-dom v20 does implement matchMedia, so reframe the block as a deliberate override (pinning prefers-reduced-motion: reduce) rather than a polyfill for a missing API. - Export MantineRenderOptions so callers can name the options type.

Dropped the false clause; kept the part that actually justifies the `as unknown as MediaQueryList` double cast (the stub omits most of the interface). - setup.ts finding 5 (folded in rather than deferred): anchored the `matches` regex to `/prefers-reduced-motion:\s*reduce/` so the override no longer also answers `true` to `(prefers-reduced-motion: no-preference)`. - renderWithMantine.tsx nit 4: the `env="test"` rationale sat on `makeWrapper`, which also builds the `env="default"` wrappers (opposite purpose). Moved it onto `renderWithMantine`, mirroring the `env="default"` rationale on `renderWithMantineTransitions`; `makeWrapper` keeps a one-liner.

Verified empirically that the helper's `afterEach` runs BEFORE the global cleanup() in setup.ts (afterEach is LIFO; setup.ts's cleanup is a setupFile registered first) — the ordering the drain depends on. The three explicit `settleTransitions()` calls in ViewHeader.test.tsx are gone; each render passes `settleMs: HEADER_ANIM_MS + 200` instead, keeping the window duration-derived. The auto-settle skips under fake timers (and no transitions test uses them). `settleTransitions` stays exported for the rare manual mid-body case. - Note 1 (settle formula was duration-only): the helper doc + the new `settleMs` option doc now say the window must exceed the longest JS chain — duration PLUS any enterDelay/exitDelay — plus rAF slack. - Nit: ViewHeader.test.tsx now states why HEADER_ANIM_MS is exported (the settle window must track the animation it settles).

Added BOTH guards the review suggested. (1) Runtime self-check: renderWithMantineTransitions captures the render container; the afterEach throws a clear error if it's already detached (cleanup ran first). (2) Pinned `sequence.hooks: "stack"` on the unit project. While verifying, found the ordering actually holds in EVERY sequence.hooks mode (stack/list/parallel) because setupFile hooks are outer relative to the helper's import-registered hook — so the comments now state that true mechanism (the pin is defense-in-depth; the container.isConnected check is the real enforcement), rather than claiming it "depends on stack". Full 3533-test unit suite passes under "stack". - Note 1 (fake-timer claim was backwards): AGENTS.md no longer says the leak "would return" under fake timers (fake clocks park Mantine's setTimeout/rAF and are discarded, not drained). The real hazard — the auto-settle silently no-ops, so real-clock work is unprotected — is now stated. The afterEach also console.warns on the fake-timer skip (was silent; the manual settleTransitions throws — this closes that asymmetry). - Note 3 (arming was last-write-wins): armedSettleMs now keeps the longest window via Math.max, so a later short-animation render can't under-settle an earlier long one. - Nit: documented `settleMs: 0` as a working opt-out for a test that drove every transition to completion itself (act flush, no wait). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * test(web): post-await self-check + correct the hook-ordering mechanism (round 6) Round-6 review of PR #1793: - Finding 1 (self-check blind in parallel): added the post-await container.isConnected re-check the review suggested (factored both checks into assertConnectedForSettle(container, "before"|"after")). While verifying it, I established the actual mechanism, which differs from what both prior comments and the review assumed: setup.ts's cleanup() is a *setupFile (outer)* hook, and Vitest runs inner afterEach hooks to completion before outer ones in EVERY sequence.hooks mode — so cleanup never races this settle. Verified: ViewHeader's real-transitions tests pass under stack/list/parallel with neither check tripping, and a same-suite `afterEach(cleanup)` probe (where the ordering CAN break) does trip them (pre-check). So sequence.hooks isn't load-bearing here; the comments in renderWithMantine.tsx, vite.config.ts, and AGENTS.md now say that. The "stack" pin stays as documentation of intent / defense-in-depth, and the two checks are the real guard against a future same-level-cleanup regression. - Nit: documented why last-write-wins on armedContainer is fine (cleanup detaches every container at once, so the last is a faithful "cleanup ran" proxy). - Nit: the fake-timer skip warning now interpolates the current test name so it's actionable at teardown.

Fixed at the source: the helper now wraps unmount() to disarm the auto-settle (clear armedSettleMs/armedContainer) — once the test has unmounted there's nothing to settle against a live tree. The guard message also now names the self-unmount cause. Verified: a probe that unmounts a real-transitions render no longer trips the guard; ViewHeader unaffected. - Nit: documented that the module-level arming assumes sequential tests (not safe under test.concurrent/describe.concurrent). - Nit: the fake-timer skip warning falls back to "(unknown test)" when currentTestName is undefined. - Finding 3 (doc weight): trimmed the AGENTS.md bullet to the *rule* (use the transitions variant only for mid-flight assertions; pass a duration-derived settleMs; no fake timers; use the returned unmount()) and pointed at the helper's own comments for the full mechanism, which now carries it at more depth.

Now the wrapped unmount() DOWNGRADES: the drain still runs (mechanism-independent — flushes queued rAF/setTimeout while window is alive; a setState on the unmounted tree is a React no-op), only the liveness assertion for that container is dropped. - Finding 2 (disarm undid round-5 max-wins arming): arming is now per-container (a Set of live containers) instead of all-or-nothing. Unmounting one tree drops only its own container; a second still-mounted tree keeps its longer window and its liveness check. The isConnected assertions run over the still-live set. Verified with probes: returned unmount() drains without tripping the guard; a second still-mounted tree is unaffected when the first self-unmounts; a bare mid-body cleanup() STILL trips the guard (it's live, not decoration); ViewHeader unchanged.

The afterEach now captures a liveness failure, always runs the act-wrapped drain (flushing queued rAF/setTimeout while window is alive), and throws afterward — so the explanatory error stands alone. Verified: a bare mid-body cleanup() still throws the guard error (now after draining); ViewHeader unchanged. - Nits: AGENTS.md now names the reachable bare-detach path (a mid-body cleanup() on a still-armed tree) rather than "a bare RTL unmount"; the settleMs doc notes arming is per-test, so in a multi-render test the longest window wins (a `0` is superseded by a longer sibling render).

Reworded to match the helper: it warns, and the hazard is that real-clock work is then unprotected, so the test depends on which clock was installed at teardown. - Finding 3 (nit): matched the console.warn string to that same corrected framing, so AGENTS.md and the warning agree. - Finding 2 (nit): a drain-time throw could discard the captured liveness error (the substitution round 9 set out to prevent, one step further). Now the drain error is captured too and the liveness error is preferred, so the explanatory error always wins.

It's now attached as the liveness error's `cause` (when the liveness error is an Error), so an act-surfaced component error from the settling render is preserved without changing which error fails the test. - Finding 2: the guard's error message pointed the reader first at the `sequence.hooks: "stack"` pin, which the file itself documents as defense-in-depth and NOT the ordering guarantee. Reworded to name the actually- reachable cause first — cleanup moved to a same-level afterEach instead of the setup.ts setupFile (outer) hook — and demote the pin to a parenthetical, so a maintainer who trips the check isn't sent to investigate a non-causal setting.

Reworded to state that observation first, then list candidate causes: (a) a bare mid-body cleanup() in the test (the reachable case today), or (b) cleanup moved off the setup.ts setupFile hook to a same-level afterEach. No single cause asserted as fact. - Nits 2a/2b: when both a liveness error and a drain error fire, the drain error is now also console.error'd (in addition to being attached as `cause`), so it's readable regardless of whether the reporter renders `error.cause` and isn't silently dropped even if the liveness error somehow isn't an Error.

Dropped that parenthetical so the log is true on both paths. - Nit: trimmed the now-duplicated outer comment to just the priority rationale (the inner comment, which mentions the log + instanceof conditional, is the accurate one). - Nit: guard message says "drained against a dead tree" (exact for both the before- and during-settle detach) instead of "drained nothing". - Nit: the message now names renderWithMantine.tsx rather than "the ordering note here", so it's self-contained out of context. eslint clean; ViewHeader unchanged; npm run ci green.

The vite.config.ts comment claimed the pin overrides a "parallel" default; corrected to say the pin is Vitest 4's own default made explicit (documents intent + guards a future default change), which is a truer reason to keep it than an override. - Nit: tied the two additions together — the post-settle check's same-level race can only arise if someone changes sequence.hooks to "parallel" (same-level hooks run sequentially under "stack"/"list"), so the pin and the post-check now reference each other rather than sitting in opposed positions.

Reproduced it (vitest --no-isolate --pool=threads --no-file-parallelism over two real-transitions files leaves one file's arming unconsumed) and documented the assumption + the onTestFinished escape hatch on the arming-state comment. - Nit: the "sequence.hooks is why the pre-check can't see the concurrent detach" clause was wrong — the pre-check is blind because it runs synchronously before the await (a property of where it sits, not the hook mode).

…ow-list (#1796) Closes #1795. Enforce localhost-only binding in code (the "never 0.0.0.0" rule was only a spec note): refuse an all-interfaces HOST — across every spelling the OS binds as the wildcard (inet_aton decimal/octal/hex, IPv6, IPv4-mapped, zone-scoped, IDNA/Unicode) — unless DANGEROUSLY_BIND_ALL_INTERFACES=true (Docker's sanctioned opt-in). Fixes the reported stdio-connect 403 by expanding the default loopback origin allow-list to all three interchangeable forms. Hardening surfaced across an extended review: closes an IDNA/fullwidth wildcard bypass, a blank-ALLOWED_ORIGINS fail-open, and the CLI/TUI OAuth-callback wildcard bind (loopback-only now, RFC 8252); canonicalizes the origin allow-list the way a browser does; derives frame-ancestors from the real embedder list (IPv6-literal exclusion verified in headless Chromium); strictPort on all three bind points; and preserves the CLI exit-code map + JSON envelope through the mcp-inspector --cli launcher path. Shared host normalization lives in core/node/hostUrl.ts. Docs + tests + smokes throughout. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

* fix(core): register peer-request handlers before connect (#1797) The roots/sampling/elicitation capabilities are advertised on the SDK `Client` at construction, so from the moment `connect()` sends `notifications/initialized` the server may issue any of those requests. The handlers, however, were registered after the handshake resolved and after `fetchServerInfo()` — leaving a window in which the SDK answered `-32601 Method not found`. `server-filesystem` asks for `roots/list` the instant it is initialized (that is how it learns its allowed directories) and lost the race, so it silently fell back to its CLI-argument directories instead of the roots configured in the Inspector. `server-everything` asks later and did not. Extract the four peer-request handler blocks into `registerPeerRequestHandlers()` and call it before `client.connect()`. None of them depend on server capabilities — only on constructor-set state. The notification handlers that do gate on `this.capabilities` stay in `connect()`, after `initialize`. Regression test drives the race deterministically with a fake transport that delivers `roots/list` synchronously from inside the `send()` of `notifications/initialized`; it fails on the pre-fix ordering.

Moved to a new `registerPeerNotificationHandlers()` called next to `registerPeerRequestHandlers()` before `connect()`. Finding 2: the timing test asserted one of the four moved handler blocks. It now injects `tasks/list` and the `roots/list_changed` notification in the same burst as `roots/list`, so moving any of the block back after `connect()` fails the test. Sampling/elicitation stay out — they park a pending request awaiting user input and have no reply to assert on. Dropped the unused `sessionId`/`setProtocolVersion` transport fields. Verified the added assertions are load-bearing: the notification assertion fails against the previous commit, the `roots/list` one against `origin/v2/main`.

It can't, normally: `RootsListChangedNotificationSchema` is a member of `ClientNotificationSchema` and absent from `ServerNotificationSchema` — the client sends it (setRoots does, at :4251). The inbound handler is defensive coverage for a non-conformant server, and dispatches `rootsChange` with our own already-known roots. Reworded the method doc and the test's header so neither states the false premise; the move itself stands (it gates on no server capability, so it belongs with the request handlers). Also from review: - Dropped the vacuous `notificationRejected` flag and its inverted comment. The SDK does not throw for an unregistered notification, so the try/catch could never observe one — confirmed by bisect, where the pre-fix failure was always `rootsChanges`, never the flag. Removing the catch also stops it swallowing a genuine throw from the injected requests. - Narrowed `replies` to responses (`"result" in message || "error" in message`) so it can't also collect client-originated requests. - Annotated the unreachable `if (!this.client)` guard with a justified `v8 ignore` per the AGENTS.md dead-guard policy. Re-verified both regression directions: the `roots/list` assertion fails against `origin/v2/main`, the `rootsChange` one against `55e25b7c`.

The new timing test asserts exactly that non-empty dispatch. Replaced with one accurate line. Comment-only. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(cli): advertise roots so roots/set is actually serviceable (#1797) Round-4 review found the same -32601 symptom on a second path: the CLI constructed its InspectorClient with no `roots` option, so `capabilities.roots` was never advertised and no `roots/list` handler was registered — yet `--method roots/set` calls `setRoots()`, which announces `notifications/roots/list_changed` to the server. A server taking up that invitation got "Method not found", after the CLI reported success. The review's suggested fix — register `roots/list` unconditionally — is not implementable: the SDK asserts the client capability inside `setRequestHandler` ("Client does not support roots capability"), so it throws during connect for any client built without the option, and `registerCapabilities` refuses to run after connect. A client that omits `roots` therefore cannot legally serve `roots/list` at all. Fixed at the layer that can fix it: `cli.ts` seeds `roots: []`, matching web (`App.tsx` always passes it). The core registration stays gated on the constructor value, now with the SDK constraint documented so the next reader doesn't retry the unconditional version. `setRoots()`'s doc claimed it "will enable roots capability if it wasn't already enabled" — it cannot, for the reasons above. Corrected, and dropped the dead `if (this.roots === undefined) this.roots = []` the very next line overwrote. Tests: a CLI test drives `list_roots` over an HTTP test server (verified load-bearing — without the seed it fails on the -32601 error text), and the core timing test gains a case pinning that roots set after connect are served with the current values, not the constructor's.

The user's roots were already in hand two lines away, on `serverSettings.roots` (lifted from mcp.json by `mcpConfigToServerEntries`). Now passed through `cleanRoots`, the same shared helper web uses, so both clients answer `roots/list` byte-identically for the same config. This matters most on the CLI because it is one-shot: `--method roots/set` sets roots on a connection torn down a few statements later, so the config file is the only durable way to give a run its roots. Same gap in the TUI (`App.tsx` built its options with no `roots` key at all), fixed the same way. The review suggested a follow-up issue for it; folding it in here instead, since it is the identical line and splitting it would leave a known-wrong client in tree. Also from review: hoisted `waiters` up with the other fields, and `injectRequest` now rejects after 1s naming the method and id rather than hanging to the vitest timeout.

Roots are the least discoverable member of that list — there is no flag, and `--method roots/set` dies with the connection — so the file is the only durable way to supply them. Said so. - cleanRoots() trusted its input's shape. `Root[]` is a compile-time type over hand-editable mcp.json, and as of this PR all three clients feed it straight from disk, so `"roots": [{"name":"Work"}]` or `"roots": "file:///work"` threw at connect. Non-array bails to []; an entry without a string uri is dropped with a warning. Hardened in the one shared place rather than three call sites. Review suggested a follow-up issue; folded in for the same reason as the TUI fix last round. - Test comment said the CLI passes a `roots: []` seed — true one commit ago. - injectRequest clears its timeout on reply (an armed timer outliving a test is the #1760 teardown class), and setRoots' doc drops the "despite what this comment used to claim" archaeology.

Reproduced against the shipped function body before fixing. A bad `name` now costs the name, not the root (it is optional, and the uri is still usable), with a warning. The doc no longer overstates what is validated. Also from review: the CLI test comment said "`cli.ts` now seeds `roots: []`" — true only of that ad-hoc test's path; and the registration comment's `(:588)` line reference is now a durable name.

Web cleans at its call site; the CLI does not, so `--method roots/set --roots-json '[{"name":"Work"}]'` stored a root with no uri, advertised it in the roots/list reply, and echoed it back as success. cleanRoots is idempotent, so calling it inside setRoots covers the CLI without disturbing web's pre-clean, and all three entry points now agree. Review filed this as an optional follow-up; folding it in for the same reason as the TUI and cleanRoots items — it is smaller than the issue describing it. Test asserts the malformed entry is dropped and the valid one survives; verified load-bearing against the bare-spread version.

All three clients clean at their call site, so nothing was broken — but the invariant was enforced by convention rather than by the class, at the very entry point this whole thread started from. `this.roots` now runs through cleanRoots, with a ternary so the `undefined`-vs-`[]` distinction that gates capabilities.roots survives. Also from review: - The CLI roots/set test provoked a cleanRoots warning without suppressing it (AGENTS.md). Suppressed, and the spy now asserts the drop was reported rather than silent. - `enables roots when previously undefined …` in coverage-backfill was named after behaviour round 5 established does not exist. Renamed, with a comment on what that client actually can and cannot do. - setRoots dispatches a copy to rootsChange, as getRoots() already did, so a listener can't push into the list we advertise. - run-method.test.ts's connectStdio now passes `roots: []` like cli.ts, so the helper matches the client shape production builds. Verified load-bearing: the constructor test fails against the raw assignment. validate / coverage / build-gate / smoke / storybook all green (run as separate stages — full `npm run ci` kept being killed mid-coverage by the environment).

It closed one of two sites: my reply conflated the notification handler's *dispatch* with the roots/list *request* handler — the latter is serialized to the wire immediately and is fine, the former hands listeners the internal array. Both copy now. Also from review: dropped the `({}) as never` in the new constructor test for the real factory the sibling tests use (this test never connects, so it is never invoked), and the needless `async` on it.

Before it, registration happened after every await in connect(), so the moment a peer request could be queued the connect could no longer fail — queue and failure path never overlapped. Registering before the handshake puts both the handshake and the post-connect `setLoggingLevel` inside that window. The catch sets status to error and drops the transport but never cleared pendingSamples/pendingElicitations; only disconnect() does, and connect() reaches it solely on the connect-timeout path (not the default). So a server that elicits at `initialized` and then fails the connect left a live pending-request modal on a dead connection — web derives it from the queue lengths with no status gate — and the elicitation's cancel() never fired, hanging any awaitUrlElicitation waiter. Extracted disconnect()'s clear-and-cancel into clearPendingPeerRequests() and called it from the catch, dispatching the change events so the UI drops the modal. CLI/TUI are unaffected either way (sample/elicit off). Test note: the first version of this test passed with and without the fix — its `requestedSchema` omitted `properties`, so the SDK rejected the inbound params and nothing was ever queued. Fixed the fixture; it now fails without the change with a queued ElicitationCreateMessage.

The test asserted only `getPendingElicitations()`/`getPendingSamples()`, which read the arrays directly — but the arrays are not what removes the modal. `usePendingClientRequests` tracks its own state off the pendingSamplesChange/pendingElicitationsChange events, so a regression that cleared without dispatching would strand a live modal on a dead connection and stay green. Both tests now assert the events fired with an empty payload; verified by deleting just the dispatches, which fails them. The connect-failure fix left the other way a connection ends uncovered: a mid-session crash goes through the transport's `onclose`, which sets status and fires `disconnect` but never touched the queues. Same two hazards, and arguably more reachable. `clearAndAnnouncePendingPeerRequests` wraps the clear plus its events, guarded on a non-empty queue so the paths that overlap (a connect failure whose dropCachedTransport also fires onclose) announce once; called from both. New test queues an elicitation, fires onclose, and asserts the queue and the event — fails without the change. Review flagged the crash path as a follow-up; folding it in, as with the earlier out-of-scope items — it is the same seam and three lines.

Moved disconnect()'s clear above its status/disconnect block so both paths agree; its change events stay batched with the other teardown dispatches. Full gate green, so nothing depended on the old ordering. - clearPendingPeerRequests' doc still named the `connect()` failure path as a caller; that path now goes through clearAndAnnouncePendingPeerRequests. Names the two real callers. - The mid-session test waited on `await Promise.resolve()` — the microtask-counting pattern this file replaced with injectRequest two rounds ago, working today only because the enqueue happens exactly one tick deep. Waits on the client's own `newPendingElicitation` instead. - The file header still called the constructor case "the last case"; it is third of five, and the two teardown cases went undescribed. Rewritten. - Restored the missing blank line between two tests, and noted why the sampling-event assertion holds for a queue that never held anything.

It holds for the arrays but not the events: the crash path announces before `disconnect`, while disconnect() batches its change events with the rest of its teardown, so they land just after. Since the events are what drives the modal, the distinction matters to the next reader. Scoped the comment rather than un-batching — un-batching would trade a documented ordering for a real behaviour change with no gain. Same rule as round 14, one level down: check the other site, then check the other axis. Also gave the new `newPendingElicitation` wait the timeout that `injectRequest` documents, so a regression that stops the enqueue fails at the wait instead of hanging to the vitest timeout.

The existing `disconnect` listeners only count events, and the two teardown tests cover the crash and connect-failure paths, neither of which goes through disconnect(). So the one behavioural change in the stack was untested in both directions, and the tidy that undoes it (regrouping the clear with the batched change events) would have stayed green. Test records the queue length from inside a `disconnect` listener; the fixture's close() never fires onclose, so it exercises disconnect()'s own ordering rather than the crash path. Verified against the pre-round-14 position: `expected 1 to be +0`. Folded the newPendingElicitation wait into a shared helper now that two tests use it.

That is the path most likely to have a modal open when it runs. Asserted after the await rather than inside the disconnect listener, since disconnect() batches the events deliberately; verified by deleting the dispatches (`expected undefined to be +0`). Header rewritten by category rather than position: it has now gone stale twice in three rounds because it counted tests ("the last two") and enumerated paths that a new test falsified. It names the three teardown paths and what distinguishes them instead.

True only if "announcing" means the `disconnect` event: the connect-failure path emits none at all, and both it and the crash path clear after their `statusChange`. Scoped to what's true. Same shape as rounds 10/14/15 — a parity asserted in prose that holds on one of the axes it could mean — which is now the fourth time, in a sentence I wrote. ElicitationCreateMessage.cancel()'s doc still credited `disconnect()` teardown; this PR made clearPendingPeerRequests() its only caller, serving three paths. Re-attributed, and promoted the no-`onRemove` note to its own paragraph with the consequence spelled out — it quietly became a three-caller invariant during this PR, and "don't splice mid-iteration" reads like a style note until you know it would skip every other entry and leave those promises unsettled.

That throw lands before the handshake, so the client can never reconnect. Worse than the -32601 this PR started from: the connection is gone rather than answering one method badly. Not a regression (the same gate lived after the handshake before) and unreachable from the three shipped clients, which all pass roots. But core/ is a library surface, and the failure is unrecoverable. Gate now reads a construction-time `rootsCapabilityAdvertised` — the thing the SDK actually asserts on — so this.roots stays free to change. setRoots' doc says what does happen on such a client: the roots are stored and readable, but no server can ask for them. Also scoped the header's claim that the connect-failure path emits no `disconnect`: true of connect()'s own catch, but on a real transport dropCachedTransport's close() fires onclose first, which does dispatch one — making the catch's own call the auth-recovery backstop.

Adding any term to the advertisement condition would leave the flag true with `capabilities.roots` absent — the same unrecoverable wedge, reintroduced silently and in the throwing direction. Now read off the built capability object after it is assembled, so divergence is structurally impossible rather than merely absent. Verified the reconnect test still fails against the old `this.roots` gate. Also: named the capability-lifetime category in the test header (the new test was none of the three it listed), moved that test below the teardown group so the group stays contiguous, and rewrapped the over-long comment line.

Reproduced before fixing: CONNECT ERROR: Client does not support elicitation capability (required for elicitation/create) Since #1797 moved registration before the handshake, that throw means the client cannot connect at all. Same wedge as the roots one, one capability over, and reachable through a documented option value rather than a future edit. Gated on a new elicitationCapabilityAdvertised, derived from the built capability object exactly as the roots flag now is. Test constructs with `{ form: false, url: false }` and asserts connect() resolves; verified load-bearing. Also made the four construction-time capability inputs (sample, elicit, receiverTasks, advertisedExtensions) `readonly`. The round-19 bug was a mutator making a construction-time fact stale, so a future setter for any of these should be a compile error rather than a review catch.

A server taking the invitation gets -32601: the advertise-then-refuse shape this PR opened with, and the last place it survived. Now built from capabilities.sampling / capabilities.elicitation, both decided just above, with the key omitted entirely if neither applies. Also made the remaining three registration gates read the built capability object like the two from the last two rounds — sampling, tasks/*, and the URL-elicitation completion handler. None could diverge today, but a mixed convention means the next reader has to re-derive which gates are safe, and adding one condition to an advertisement block is exactly how elicitation broke. Five gates, one rule now. Test asserts a receiverTasks+elicit:false client advertises tasks.requests with sampling and without elicitation; verified load-bearing.

Second client in the same test asserts `tasks` survives (list/cancel are still serviceable) while `requests` is absent rather than empty; verified against `requests: taskRequests`. The header regained a numeral four commits after round 17 rewrote it by category to stop exactly that, and it was already stale. Dropped, and named the third category — advertise-only-what-you-serve, which is about the capability object rather than a registration gate.

Round 13 recorded the samples-vs-elicitations asymmetry as deliberate on two grounds: nothing internal awaits a sample, and the transport is gone by then. The first still holds; the second is false on one path, and it is a path this PR created. `connect()`'s catch drops the transport only when `!transportHasAuthProvider`, so on the HTTP+OAuth path — web's ordinary authenticated case — it is retained and the caller reconnects over it. A sampling request queued during the handshake was then discarded with the connection still live: no response frame ever written, and the server waits forever for a reply to a request we accepted. Accept-then-silence, which is worse for the peer than the -32601 this PR opened with. SamplingCreateMessage.cancel() mirrors the elicitation one — settles (rejects, what the UI's decline path already sends and the SDK turns into an error response) without calling onRemove, since the caller iterates the queue and clears it. clearPendingPeerRequests loops it like the elicitations. Also corrected two comments that assumed the catch always tore the transport down, and noted that the retention is gated on transportHasAuthProvider alone — independently of isConnectAuthRecoveryError, which gates only the status hold. Test asserts settlement rather than a wire frame, since on the disconnect() path the transport is closed before the settle; a later respond() throwing "already resolved or rejected" is the proof. Verified load-bearing.

That promise only gets a consumer when the server polls tasks/result, so a task sitting in input_required has no handler attached — and the settle added last commit surfaced as an unhandled rejection. Not hypothetical: the repo already worked around it test-side, with a helper that reaches into private state to attach no-op catches, whose comment describes this exact race. Fixed at the source instead — one `void payloadPromise.catch(() => {})` at creation, which also covers the pre-existing cancelReceiverTask path. Removed the now-redundant helper and its two call sites. Verified: dropping the source line makes that suite report two unhandled rejections. Corrected SamplingCreateMessage.cancel()'s doc — its "no response frame is ever written" rationale is true of the plain shape only; a task-augmented sample already answered the wire with a CreateTaskResult, so settling it is about not leaving the task in input_required limbo. Nits: generalized the enqueue wait helper to both events so the sampling wait gets the timeout the elicitation one has; moved the sampling teardown test back into the contiguous teardown group; named the settle property in the header; fixed the fixture doc that still claimed to record replies.

Probed it: the premise is wrong. The SDK asserts the notification capability too — `notification()` rejects with "Client does not support roots list changed notifications" and nothing reaches the wire. No spec violation and no invitation; what actually happened is that setRoots provoked that rejection and logged it as "Failed to send", implying a transient failure where the truth is structural. Kept the early return on that corrected basis: it stops us provoking a rejection we know will come, and warns accurately instead. Doc and comment say the SDK is the enforcer rather than claiming this guard is what keeps the wire clean. The test pins the end state (no invitation for roots we can't serve) and passes either way — recorded as such rather than presented as a regression guard, since it isn't one.

Split into rootsListChangedCapabilityAdvertised, mirroring urlElicitationCapabilityAdvertised, which already reads its assertion's sub-field; rootsCapabilityAdvertised keeps the roots/list registration, where presence is what setRequestHandler checks. Also moved the new test out of the gate pair it had split — it is a runtime-emission case, not a registration-gate one — and extended the header's converse-category paragraph to cover notifications, which indexes it without inventing a category. Reflowed the setRoots doc paragraph in one pass (111-char line from the last commit, plus a ragged orphan from an earlier edit).

That reword happened in core/, but the same premise had been written into the two comments justifying the CLI's roots seed, and they still asserted it. Both now state the real pre-fix failure: a server asking for roots on its own got -32601, and roots/set could not announce at all. Also fixed the warn message under the round-28 gate: it named the roots capability while the gate is on roots.listChanged — precisely the pair that split was made to distinguish, so a client advertising `{}` would have been told it advertised nothing.

That map holds the modern tasks/* frames the SDK's era gate refuses to route, so the SDK's chained _onclose doesn't know about them: a Tasks-tab poll in flight when the server died waited out its own 30s timeout and reported a timeout for what was a crash, on a connection that had already dispatched `disconnect`. Pre-existing — both the map and the crash path predate this PR. Fixing it here because the invariant it violates is one this PR wrote down: "every path that ends a connection has to clear that queue, announce it, and settle each entry", in clearAndAnnouncePendingPeerRequests' doc and the timing test's header. One channel was true of one path out of three. Test starts a raw-wire request and fires onclose; without the call it hangs to the vitest timeout, which is the symptom. Checked the two siblings and left both: taskInputAbortControllers is already unblocked via the elicitation cancel the crash path performs, and activeToolCallAbortController rides an ordinary client.request the SDK settles itself.

Round 31 established that scoping so the code wouldn't imply an impossible state; the prose then un-scoped it. Split into its own paragraph with its own scope clause, and reflowed both in one pass rather than nudging breaks.

On the failing path the raw-wire test left the production 30s timer armed, so a regressed run got the intended failure plus a stray unhandled rejection up to 30s later — the armed-timer class the file's own comment names, on the failure path. `settled` is marked handled before the race. Verified: with the fix removed the run fails with "raw-wire request not settled by teardown" and no unhandled rejection.

Both were wrong: `Promise.race` attaches a rejection handler to every input, so `withTimeout(settled, …)` on the next line already marks it handled. Verified with a standalone script — no unhandledRejection fires, and the pre-fix version was equally safe. Removed the line and the comment. The comment mattered more than the line: it told the next reader that `Promise.race` does not mark its losers handled, which is false and would cost them elsewhere. Kept the true half by setting `timeout: 50` on that test's client, so a regression leaves no 30s timer armed and fails with `Raw request "tasks/get" timed out after 50 ms` — more self-describing than the raced generic message.

Verified it isn't one: `safeDisconnectTimeout` defaults to 0 and the only caller anywhere that passes a value is a single test, so nothing is drained in production; and the drain polls the SDK's `_responseHandlers`, which never holds raw-wire ids, so those were never eligible regardless.

Noted, so someone adding one later knows it would inherit a 50ms budget rather than reading the comment and looking elsewhere. The two installReceiverTaskResponseBypass guards read `this.receiverTasks` while the five gates around them read the advertisement. Installing the bypass mutates the Protocol's _requestHandlers map, so it is registration — same as the setRequestHandler it follows. Equivalent today; aligned so the convention is uniform rather than something the next reader has to re-derive per site. The genuinely-runtime `receiverTasks` reads are left. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-38 — one predicate for the whole bypass mechanism (#1797) Round 37 moved the bypass *install* guard to the advertisement and left the three branches it controls on the raw option, splitting one immutable fact across two sources. The dead direction is the harmful one: if the tasks advertisement ever acquires a condition — the exact edit that produced the elicitation wedge — then advertised goes false while receiverTasks stays true, the bypass is not installed, and the handler still returns `{ task }` into the SDK's validating wrapper, which rejects it. That is the breakage the bypass exists to prevent, and before round 37 it could not happen because install and branch read the same field. All three now read tasksCapabilityAdvertised. `receiverTasks` is left where it belongs: assigned once, and driving the advertisement. Also noted that the wrapper's own check is redundant with its install guard and kept deliberately, since it must agree with the handler branch.

The crash path doesn't clear it, the connect() failure catch doesn't, and connect() never reset it — so a record created in one session survived into the next connect() on the same instance, and `tasks/list` is answered from that map. A new server would be told about a task it never created. Reachable in web (the only client with receiverTasks): a task-augmented sampling/createMessage arriving in the handshake window creates a record; if that connect then fails with a 401, App.tsx retries connect() on the same instance. Cleared at the top of connect() rather than only on the crash path — the auth-recovery retry means ending a session isn't the only way a new one begins, and starting clean covers every route in. disconnect() keeps its clear via the same extracted helper. Pre-existing — the crash path never cleared these — but the handshake window this PR opened is what lets a receiver task exist before connect resolves, and this was the one member left outside the invariant the PR documented. Test verified load-bearing.

Two of the other four have real symptoms on the same crash-then-reconnect path: - subscribedResources — the modern subscribeToResource early-returns on a uri already in the set, so after a reconnect the user's Subscribe click silently sends nothing to the new server while the UI keeps listing it. - cancelledTaskIds — a leftover id mislabels a *new* task sharing it as cancelled rather than failed, and server task ids are often short. taskInputAbortControllers leaked un-aborted controllers. modernLogLevel had the opposite asymmetry: disconnect() cleared it so it couldn't leak (#1629), but nothing restored it, so a reconnect after an explicit disconnect silently lost the user's configured level while a reconnect after a crash kept a mid-session override. It is now recomputed from serverSettings the way the constructor does, so both routes agree. clearReceiverTasks became resetSessionState, called from the same place. Tests cover the two symptomatic siblings and now assert receiver tasks through the `tasks/list` handler — what a server actually sees, and the symptom itself — which also removed the unjustified `as unknown as` the previous commit added. The remaining cast is justified in place, since cancelledTaskIds has no public reader.

On the one path that reconnects the *same* instance — auth recovery — the control then read Off while every modern request carried `_meta` logLevel "debug", the default. A tool whose job is showing what you send should not disagree with itself about what it sent. The control now re-seeds from the active server's settings exactly as setupClientForServer does, instead of blanking. Also from review: - Added the tests the restore never had, covering both halves: a mid-session override does not survive a reconnect, and a disconnect no longer drops the configured level (the #1629 half, and the actual behaviour change). - resetSessionState's doc claimed "every piece of state scoped to one connection", which invites assuming membership rather than checking it. Now states the rule: state a new session would misread; what only needs settling on the way out stays with the teardown paths. - Header: session-scoping paragraph moved below the outbound one to match test order, and it now names all five members rather than three. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * refactor(core): one derivation for the modern log level (#1797) Round-42 review: the configured level was computed independently in four places — twice in InspectorClient (constructor, resetSessionState) and twice in App.tsx (the seed and the re-seed). The client and the Logs control agreed only because four sites happened to compute the same expression, and any drift reproduces exactly the symptom the previous commit fixed: the control reading one level while every modern request stamps another. Extracted resolveModernLogLevel into core/mcp/types.ts beside DEFAULT_MODERN_LOG_LEVEL; all four call sites use it, with the web mapping undefined→null at its own boundary (display, not a second derivation). Also from review: - disconnect()'s comment still credited itself with preventing the #1629 leak, which resetSessionState now prevents. It says what the line does now — read "not opted in" while disconnected — and notes the web control deliberately shows the configured level in that window. - resetSessionState's doc claimed an un-aborted taskInputAbortControllers entry "leaks a paused poll loop". Both registration sites release in a finally, so nothing leaks permanently; the abort closes the window between a crash and the unwind. Softened, and it now has the test it lacked — the only member of the five without one. - Noted in App.tsx that the re-seed depends on activeServerIdRef still holding the outgoing id (it syncs in a passive effect), so an eager clear would silently drop it to the default. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(core): reset the subscription stream state with the set it derives from (#1797) Round-43 review: resetSessionState cleared subscribedResources but left modernStreamState, so a crash-then-reconnect on the same instance held an empty set alongside `{ active: true }` — a combination the rest of the file treats as impossible, since onModernSubscriptionClosed and onModernReconnectFailed both compute `active` from `subscribedResources.size > 0`, and the comment at :4712 asserts a terminal drop clears both. No symptom today only because the UI mirror resets itself independently, in another file — which is the arrangement this PR has spent its rounds removing. Clearing it here also announces the reset; that set's every other mutation dispatches. Also from review: - The web re-seed treated "no server found" as the default level rather than Off, because resolveModernLogLevel returns the default for absent *settings*. Reachable via a second disconnect after a crash, and via removing the active server. Now distinguishes the two. - Converged the two injectRequest copies: withTimeout takes an optional onTimeout, so both drop their waiter on the timeout path. The newer copy had lost exactly the cleanup that was round 33's reason for leaving the original alone. Test seeds the stream state a live subscription would have left; verified load-bearing (the earlier version passed either way, since the fixture never activates a stream). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(web,core): correct the re-seed branch; share the subscription-stream reset (#1797) Round-44 review. My round-43 fix traded one wrong branch for another: it read `?.settings`, which is undefined both when no server matched *and* when the server has no settings node — and the second is the common case (a hand-written mcp.json entry never opened in Server Settings). Those servers showed Debug while connected and Off after disconnect, which is exactly the client/UI disagreement rounds 41-42 removed, with no modernLogLevelChange event to reconcile it. Now branches on the server. Worth noting no test would have caught it: App.tsx is a documented exclusion from the coverage gate. Also from review: - resetSessionState cleared subscribedResources without announcing it, two lines below a comment arguing that every other mutation of that set dispatches. And it took two statements of a six-statement cluster disconnect() clears together — leaving modernReconnectAttempts (a new session's first drop would back off as if it were the old one's nth), modernListenGeneration (the bump that makes an in-flight re-listen bail), and a stale modernSubscription. One resetSubscriptionStream helper now serves both, announcing both axes; disconnect() keeps only the live stream's best-effort close. That also removed the file's one assignment to modernStreamState that bypassed its setter. - The stream-state test pinned the value, not the dispatch — the half the UI actually tracks. Now asserts both; verified against a bare field assignment. - onModernSubscriptionClosed's comment claimed the disconnect reset always clears the set; on a crash it doesn't until the next connect. Says so.

Dead text where it sat, and the most load-bearing comment in the batch. Moved, not reworded. That is round 32's finding in production code, from the same cause: inserting anything between a doc block and its method is a move that needs checking, prose or code. Also from review: - resetSubscriptionStream announced the cleared set before updating the stream state derived from it, so a listener in between saw an empty set with an `active` stream — the combination the helper exists to prevent, exposed by its own dispatches. Both fields move first, then both are announced. The onModernSubscriptionClosed comment now says that window is never observable, which is newly true. - The test header called the log level "cleared"; it is re-seeded, which is the #1629 half of the test twenty lines below. Says "reset", with the distinction spelled out, and the paragraph reflowed in one pass.

Not guaranteed on the connect path — an `onerror` without an `onclose` leaves the transport up, connect() reuses it, and the reset then drops the last reference to a stream still open on the server. Nothing can close it afterwards: the `closed` handler bails on the bumped generation, and `closed` never resolves for a live stream. Before the extraction the surviving reference was eventually closed by refreshModernSubscription as `previous`, so this was newly unclosable. The helper now closes it itself, best-effort, after the dispatches so the round-45 ordering is unaffected; disconnect() drops its two hand-rolled lines. Also from review: - The session test pinned the subscription set's value but not its dispatch — the half the UI tracks, and the gap round 43 closed for the stream axis one line away. Both now asserted; verified load-bearing. - resetSessionState's doc said disconnect() "clears all of this", which is true by duplication for two of the five members; it now says a sixth has to be added in both places. And "the teardown paths" handle the in-flight tool call only on the disconnect route — on a crash it is callTool's own finally. Named.

It is two and three — and the member the enumeration dropped is the one that is *paired* rather than duplicated: modernLogLevel is re-derived here and blanked in disconnect(), deliberately. Both corrected. - `subscription.closed.then(...)` had no rejection handler, unlike every other promise around that stream. Newly reachable: before the last commit a connect-path reset dropped the reference with `closed` permanently pending, so the chain never settled at all; closing the stream is what makes it settle. Added, with the Node-terminates reasoning the file already applies to payloadPromise. - The listen-stream test exercised transport reuse without asserting it — the half that makes "still open on the server" true. Counts factory calls now, so the premise fails loudly if a future change recreates the transport rather than silently ceasing to apply.

It doesn't: closing resolves it. What that close newly reaches is the handler running at all, where the reference used to be dropped with `closed` pending forever. And chaining after `.then` also swallowed handler throws — silently abandoning a re-listen on the path whose job is recovering a dropped stream. Now the second argument to `.then`, scoped to the rejection, with the comment saying which half is which. - `closing?.close()` reaches into third-party code from `disconnect()`'s straight-line teardown, none of which is inside a `try` — a synchronous throw would skip the raw-wire rejects, the task aborts, the receiver-task clear and nine dispatches, silently, since most callers catch a disconnect(). Best-effort now against both failure modes. - Header indexes the listen-stream test: same category, but a release obligation rather than a misread one. - Its comment described the generation guard, which the stub can't exercise; marked as production behaviour. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-49 — pin the best-effort close, unorphan the doc (#1797) Round 48 made `resetSubscriptionStream`'s close best-effort against both a rejected promise and a synchronous throw, but nothing exercised either arm: both `modernSubscription` stubs in the tree resolve. On the `disconnect()` path an escaping failure would silently skip the raw-wire rejects, the paused task-input aborts, the tool-call abort and `clearReceiverTasks()` — the findings rounds 13 and 30 closed, re-opened at once with a green suite. Two table-driven cases now seed a `close()` that throws and one that rejects, and assert teardown continued past it. Also: the `.then` comment gave opposite verdicts on one mechanism (an unhandled rejection is named unacceptable, then chosen for a handler throw) — reworded to say the handler cannot throw today and why the shape is defensive; and `refreshModernSubscription`'s doc block, orphaned two methods up since before this branch, moved onto the method it describes. Closes #1797 * review: round-50 — sweep the queues start-clean, unify the close (#1797) `resetSessionState`'s doc excluded the peer-request queues and the raw-wire map because "the teardown paths handle them" — true of the paths that run. An `onerror` without an `onclose` runs none of them: it flips status to "error" and leaves `baseTransport` cached, so a `connect()` on the same instance reuses a live transport. That is the route the round-46 stream close was built on, and it strands these two the same way — the web pending-request modal is derived from the queue length with no status gate, so it outlives the session, and answering it writes a response for the old request id onto the new connection. Both are now swept start-clean beside the reset (both helpers are idempotent, so the routes that already ran them are unaffected), the end-clean clears stay put for the `disconnect`-event consumer, and both docs say which is which. Also folds the three subscription `close()` sites onto one `closeSubscriptionBestEffort` helper, so all three absorb a synchronous throw as well as a rejection — at `refreshModernSubscription`'s first site the reference is already dropped, so a throw there both leaks a live stream and aborts the refresh before its replacement is opened. Closes #1797 * review: round-51 — pin the sweep's ordering, name the category (#1797) The connect-start sweep must sit after `resetSessionState()`, and the two calls read as independent. Cancelling a task-augmented peer request settles it synchronously into the record callback, which ends in `upsertReceiverTask` — a no-op only because `clearReceiverTasks()` just emptied the map. Hoisted, it would emit a `notifications/tasks/status` for the outgoing session's task onto the transport the connect is about to reuse. Stated at the call and pinned by a test (which fails on the hoist). Adding that third caller also made five docs stale, all describing the old set by count or as "teardown" — the class round 23 diagnosed. All five now name the category: every route out, plus the top of …

* test(cli,tui): typecheck the __tests__ dirs (#1791) The cli/tui `typecheck` scripts only checked `src` (the src-only tsconfig excludes `**/*.test.*`), leaving the `__tests__` dirs — which do the most `as` casting — with no tsc pass. Add a `tsconfig.test.json` per client that includes `__tests__` with the test-exclusions dropped and the test-only path aliases (`@modelcontextprotocol/inspector-test-server`, the `@inspector/core/*` deep paths, express/vitest) resolving what vitest resolves, then fold `tsc -p tsconfig.test.json` into each `typecheck`. Fixes the 76 errors it surfaced: - cli: a wrong `@modelcontextprotocol/inspector-core/...` module specifier (should be `@inspector/core/...`; only a type import so vitest never caught it), `r.headers` optional-access guards, and partial OAuth mocks replaced with typed `makeFakeCliOAuthClient()` / `makeFakeServerSettings()` factories instead of `as` casts. Adds `@types/express` (devDep) so the transitively aliased test-server source typechecks, mirroring clients/web. - tui: rest-param signatures on the App OAuth spies (fixes the spread-arg and narrow-return errors), a widened callback param (`iss?`), a `makeFakeServer- Settings()` factory for the tuiOAuth tests, required OAuth-metadata/client fields in AuthTab, and a loosened `entry()` message param for the deliberately-malformed wire messages HistoryTab's defensive branches render. Gate coverage only; no runtime behavior change.

Now typechecked. - App.test.tsx: type `callTool` against `InspectorClient["callTool"]` (+ the Parameters<…> wrapper) so its `mockResolvedValue` payloads are checked, and give `clearOAuthTokens` an `async () => {}` impl so the mock actually returns the `Promise<void>` its type promises. - AGENTS.md: correct the per-client alias-set description (cli's is widest, tui's is core+react only, launcher's has no paths) and note launcher's config file lives in its test project, not the src project.

This closes the class the review kept surfacing by hand (launcher/__tests__ in round 3, launcher/vitest.config.ts in round 4) — a new top-level file can no longer go untypechecked silently. Wired into `npm run ci` and the GitHub workflow. - launcher: reorder `validate` to run `typecheck` before `build` (matches tui and the documented order), and make `typecheck` self-contained — it now runs both `tsconfig.json` and `tsconfig.test.json`, so running it standalone means the same thing it does in cli/tui. - makeFakeCliOAuthClient: note on the comment that the typing covers the defaults, not `overrides` (a bare vi.fn() override is Mock<(...args)=>any>). - Docs: README table + AGENTS.md updated for the new guard and the corrected launcher typecheck/validate ordering.

Verified: stripping `npm run typecheck` from launcher's validate now fails the guard. - Nit 3: switch `tsc --listFiles` → `tsc --listFilesOnly` (identical file list, ~4× faster: whole guard 23s → ~4s). Now cheap enough for the inner loop, so it moves into `validate` (right after verify:format-coverage) instead of a standalone ci step — matching its sibling. Removed the separate ci-chain entry and GitHub workflow step (validate covers it). - Nit 4: `npx --no-install tsc` so a missing local tsc fails fast instead of reaching for the registry (matches verify-build-gate.mjs). - Nit 5: corrected projectFiles' JSDoc to describe the filter that's actually there (drops repo-external + node_modules paths; core/ + test-servers/ stay but are harmless). - Finding 2: fixed the 2-space misindent on the new root package.json line (prettier --write).

Also accepts `--project`. - Nit 3: on a tsc config error, echo the `error TS…` diagnostic (scanning both streams — tsc prints config errors to stdout) so a broken tsconfig is self-explaining rather than surfacing only as a misleading "file in no project" report. - Nit 4: refreshed the CI workflow's stale "Validate" step name/comment (it now runs the coverage guards + validate:core + per-client typecheck). - Nit 5: reworded the `.d.ts` carve-out comment to read as pre-emptive (there are none under cli/tui/launcher today).

No-op on today's tree (no client `.mts`/`.cts`); confirmed a tracked `.mts` with a type error is now caught. Ambient `.d.{ts,mts,cts}` stay excluded. - Nit 2: drop the unused `export` on `rootReachedCommands` (internal to the lib; nothing imports it, and scripts/ isn't eslint-gated to catch dead exports).

Fixes the AGENTS.md avoid-double-casts violation. - Nit 3: write all seven FakeClient OAuth wrappers as `(...a: Parameters<InspectorClient["…"]>)` (the three zero-arg ones were hand-written `()` forwarders), so the block comment's "forward the same Parameters<…> tuple" is literally true and a future added parameter can't be silently dropped. - Nit 2: update the five places that still described the guard as `.ts`/`.tsx` only to `.ts`/`.tsx`/`.mts`/`.cts` (script header + trackedSourceFiles JSDoc, AGENTS.md ×2, README.md).

MALFORMED's single cast stays (load-bearing). This leaves MALFORMED as the file's only cast, matching what the comments describe. - Nit 2: add `rootReachesScript` to scripts/lib/npm-scripts.mjs and have each coverage guard assert its SIBLING is still wired into the root `validate`. A guard can't detect being unrun itself, but the two now vouch for each other, so dropping either from `validate` is caught by the other (only deleting both slips through). Verified: removing verify:typecheck-coverage from validate now fails verify:format-coverage, and vice-versa. Nits 3 (git-index visibility) and 4 (pre-existing as-never/as-unknown casts in tests — out of scope, none added by this PR) left as agreed.

(Splits each script on `&&`/`||`/`;` so a flag on one command can't taint another.) Verified a `typecheck` using `tsc … --noCheck` now fails with a clear message; `--noCheck` is a live idiom here (cli's test-servers:build), so this is a real copy-paste hazard. - Nit 2: reachableScripts (shared lib) now also follows npm's implicit `pre<name>`/`post<name>` lifecycle hooks, so moving a gate into e.g. `prevalidate` is recognized instead of producing a false "not reachable" failure (cli already uses a `pretest` hook). Verified. - Nit 3: AGENTS.md "Test placement" now states the Node clients (cli/tui/ launcher) keep all tests in `__tests__/`, enforced by verify:typecheck-coverage (a co-located src test lands in no tsconfig project). - Nit 4: noted on the factory comments that `Partial<…>` overrides admit an explicit `undefined` for a required field (exactOptionalPropertyTypes off).

Excluding it also makes such a test land in no tsconfig project, so verify:typecheck-coverage catches it — making the AGENTS.md placement rule literally true for all three clients. - Finding 2: verify-typecheck-coverage now catches both remaining ways a typecheck could check nothing: (a) case-insensitive `--noCheck`/`--nocheck`/ `--listFilesOnly` on the command, and (b) `noCheck` set in the tsconfig itself (detected via `tsc --showConfig`, which surfaces it from the config or its extends chain). Verified both fail the guard. - Nits 3 & 4: restructured into an explicit gate-integrity phase (wiring + neutered + config-noCheck + no-projects) that reports under its own accurate header and exits BEFORE the file-coverage pass — so an inert gate no longer prints file-remediation advice, nor buries the real cause under an "in no tsconfig project" line for every file that gate covered. The one CIMD OAuth E2E integration test that flaked in the coverage run passes 32/32 in isolation and on re-run; unrelated to these script/config changes.

All three clients now exclude `**/*.test.*` (one glob, covering .ts/.tsx/.mts/.cts) — which is also exactly what AGENTS.md already claims. Verified a `src/probe.test.mts` is no longer emitted and now fails the guard. - Finding 2: the gate-integrity phase no longer prints a false "names no `-p <project>`" line when config-`noCheck` disables projects — the condition now keys off `projects.length` (harvested), not `checking.length` (post- filter), so a client whose projects were all config-disabled shows only the accurate per-project lines. - Nit 3: recorded the boundary on the phase comment — it does not detect shell-level failure suppression (`… || true`, `; exit 0`). - Nit 5: the file-coverage remediation now leads with "for a co-located test, move it to `__tests__/`" (adding it to the src `include` would reintroduce the build emit) before the general add-to-include advice.

Also harvests `-b`/`--build` project paths. Verified `tsc --noEmit && tsc --noEmit -p tsconfig.test.json` now reports OK. - Finding 2: CLIENTS is no longer hardcoded — it's derived from the `cd clients/<x> && npm run validate` entries in the root `validate` chain (minus an explicit web exclusion), so a new Node client is auto-required, matching the repo-wide reach of its sibling verify-format-coverage. Added a guard-would-check-nothing bail if the derivation yields an empty set. Verified a new `clients/newclient` is picked up and its uncovered file flagged. - Nit 3: the phase-2 remediation now leads with the general add-to-`include` advice and only appends the "move it to __tests__/" note when a failing path is actually a test file (was misdirecting plain files). - Nit 4: AGENTS.md no longer says the test config includes "only" __tests__ (launcher's also includes its vitest.config.ts). (Two different web integration tests each flaked once under parallel load during the coverage runs — both pass in isolation and on a clean re-run; timing- sensitive and unrelated to these script/doc-only changes.)

The chain derivation was fail-open: a root-chain edit that kept running a client but didn't match the strict regex silently dropped it from the required set (112→53 files, still green). Disk is fail-closed — a client can't be silently dropped, a new client with a typecheck is auto-required, and web (no typecheck script; builds via `tsc -b`) is excluded on its own, so the explicit exclusion is gone. The existing `rootRunsClientValidate` wiring check still verifies the root chain runs each — now LOUD when it doesn't. Verified: `cd ./clients/tui && …` now hard-fails the integrity phase instead of silently shrinking coverage; `cd clients/tui && npm run build && npm run validate` stays gated. Removed the now-unused `clientsRunByRootValidate` from the shared lib. - Nits 2 & 3: documented the two unreachable-today limitations on typecheckProjects — a solution-style `tsc -b` (empty `files` + `references`) would under-report, and the implicit-tsconfig fallback assumes no file operands. - Nit 4: refreshed the file header to mention `-b`/`--build` + the implicit `./tsconfig.json` (only the JSDoc had been updated).

Now every `clients/*` with a readable package.json must EITHER declare a `typecheck` (→ enrolled) OR be in an explicit EXEMPT map (`clients/web`, reason: `tsc -b`); anything else is a hard gate-integrity failure. This is fail-closed on the rename axis too, and web's skip is a stated decision rather than an accident of which scripts it declares — so web gaining a `typecheck` no longer auto-enrolls it into the solution-`-b` false failures. Verified: renaming tui's `typecheck` now hard-fails; a `tsc -b` on web stays exempt. - Nit 3: `rootRunsClientValidate` normalizes a leading `./`, so `cd ./clients/tui && npm run validate` (which genuinely runs it) is no longer a false "no longer runs" alarm. - Nit 2: README/AGENTS/script-header prose no longer names a fixed cli/tui/launcher scope — they describe the disk-discovered "every clients/* with a typecheck script (web exempt)" rule.

Now an anchored regex (escaped dir + optional leading `./` + a trailing boundary). Verified the sibling case now hard-fails. - Nit 2: a `clients/*` dir holding tracked TS but no readable package.json is now a gate-integrity failure (was treated as "not a client"), so the "fail-closed on every axis" claim holds. Verified. - Nit 3: readdirSync is wrapped, so a missing `clients/` dir yields the intended "found no clients/* dir" message rather than a raw ENOENT stack. - Nit 4: EXEMPT's reason is now surfaced in the success line ("clients/web exempt: typechecks via tsc -b …"), so the exemption is visible at runtime, not only in source. (Also moved `isRequiredSource` above nodeClients — nit 2's new tracked-TS check calls trackedSourceFiles at module-init, which referenced it before init.)

So a quoted `-p "tsconfig.test.json"` (a form tsc accepts) made the typecheck guard report every file that project covers as uncovered, and a quoted `cd "clients/tui"` in the root chain tripped a false wiring failure. Moved tokenize() (now single+double quote) into the shared lib, imported it into both guards, rewrote typecheckProjects to walk tokens (`-p`/`--project`/`-b`/`--build` → next token), and strip quotes before the `cd` match in rootRunsClientValidate. Verified both quoted forms now pass. - Nit 2: a stale EXEMPT key (a dir that no longer exists) was asserted in the success line unchecked. nodeClients now fails if an EXEMPT key isn't a real `clients/*` directory. Verified. - Nit 3 (build/dist filter belt-and-braces) left as a recorded boundary.

Now matches on the token basename (`isTsc`), keeping round-17's quoting fix while restoring the tolerance. Verified a `node_modules/.bin/tsc` typecheck reports OK. - Nit 2: `rootRunsClientValidate` stripped quotes for the `cd` match but tested `npm run validate` against the unstripped string, so `npm run "validate"` false-failed. Both halves now test the stripped string. - Nits 3 & 4: documented on typecheckProjects — the contrived `--noCheck false` (checking on) is still treated as disabling, and the `&&`/`||`/`;` split runs before tokenizing (a quoted operator inside an arg would split mid-token, unreachable for project paths).

Added it explicitly to `clients/cli/tsconfig.test.json`'s include (zero source changes; verified a bad line in it now fails cli's typecheck). Softened the AGENTS.md clause that implied the whole test-server source is transitively covered. - Nit 2: `rootRunsClientValidate` now also recognizes the `npm --prefix <dir> run validate` invocation form (was `cd`-only). - Nit 3 (stderr spy drops the completion-callback overload): left as-is — latent, not live (no exercised path awaits a stderr drain), and adding typed overload params would reintroduce the write-overload complexity the round-1 vi.spyOn refactor removed.

So the root chain could run a client's `validate:fast` while the guard kept measuring its `validate` (unrun), green. Anchored the tail to a boundary (`/\brun validate(?=$|[\s&;])/`). Verified `validate:fast` now hard-fails. - Finding 2: durably close the test-servers/src class instead of point-fixing. Added a SHARED_ROOTS check — every tracked TS under `test-servers/src` + the root `vitest.shared.mts` (the `format:check:shared`/`lint:shared` surface) must land in the GLOBAL union of client projects. So a NEW unimported bin entry is caught (not just server-composable.ts, named in round 19). Verified a fresh `server-orphan-bin.ts` now fails. Zero source changes — the union already covers 15/15. - Nit 4: the integrity message and rootRunsClientValidate docstring now mention the `npm --prefix` form too.

This closes BOTH round-21 findings at once: - Finding 1 (stale allowlist fail-open): a rename of `test-servers/src` no longer silently drops it — its files reappear in the required "other" set and hard-fail (verified: `git mv test-servers/src test-servers/source` now fails instead of going 127→113 green). The subtractive `core/` exemption is fail-closed on staleness for the same reason. - Finding 2 (allowlist vs deny-by-default): a new top-level TS location is now auto-required (verified `tools/probe.ts` is flagged), matching the repo-wide reach of the sibling verify-format-coverage. - Nit 3: added the shared-source clause to the README table row (AGENTS got it last round). Header comment updated to describe the non-client coverage.

So a `core/*.tsx`/`*.mts`/`*.cts` or a co-located `core` test got no tsc pass from anything. Narrowed the exemption to exactly that shape (`isExemptCoreFile`): a core `.ts` that isn't a co-located test. So a core `.tsx`/`.mts`/co-located test is now required in some project. Zero-fix today (0 such files); verified `core/mcp/probe-widget.tsx` and a co-located core `.test.ts` are now flagged. - Nit 2: `EXEMPT_ROOTS` is now a Map (dir → reason) and its reason is surfaced in the success line alongside the client exemption. - Nit 3: the non-client miss message is now the general "in no client's tsconfig project"; the `test-servers` remediation clause is conditional on an actual `test-servers/` path (tracked via `nonClientMisses`, not string-sniffing the composed message). - Nit 4: success line says "(N clients + non-client)".

So a `core/**/__tests__/*.test.ts` (a live layout — `core/mcp/__tests__/fakeInspectorClient.ts` already sits there) was flagged though web checks it. Now mirrors the UNION: under `__tests__/` → exempt `.ts`/`.tsx`; otherwise `.ts` minus co-located `*.test.ts(x)`. Verified a core `__tests__` test now passes while a core `.tsx` outside `__tests__` stays required. - Finding 2: `EXEMPT_ROOTS` was a Map whose keys nothing read (round 22 replaced its filter with hardcoded `isExemptCoreFile`) — a phantom registry. Collapsed to a single `CORE_EXEMPT_REASON` const used in the OK line. - Nit 3: README/AGENTS scope descriptions updated (core is no longer wholesale excluded; the non-client set is deny-by-default).

This was the last whole-tree exemption wider than the gate it defers to. Now web is ENROLLED: a client with no `typecheck` script but a `tsconfig.json` `references` array is measured through those reference projects (`tsc -p <ref> --listFilesOnly`), and is wired iff its `validate` runs `tsc -b` (`validateRunsTscBuild`). EXEMPT is now the empty escape hatch. Verified: a web-root `playwright.config.ts` with a type error is now flagged, and dropping `tsc -b` from web's build hard-fails the integrity phase. Zero-fix on the tree — the union of web's 4 projects covers all 625 tracked web files. - Nit 2: assert `core/` exists (the OK line unconditionally states its exemption) — parity with the EXEMPT stale-key check. - Nit 3: a `core/` miss now gets core-specific remediation (widen web's `tsconfig.app.json` include, not a cli/tui project). - Nit 4: README/AGENTS scope descriptions corrected — web is enrolled (not exempt), and the exact core-exempt shape (app `*.ts` minus co-located tests + test `__tests__/**/*.{ts,tsx}`). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * chore(scripts): round-25 — drop redundant core exemption; guard tsc -b --noCheck Responds to the round-25 @claude review of #1799: - Finding 1: enrolling web (round 24) made the hand-maintained `core/` exemption both redundant and fail-open — web's measured `tsc -b` projects already cover core, and the mirror could go stale (narrowing web's include let an unimported core error pass). Deleted `isExemptCoreFile`, `CORE_EXEMPT_REASON`, the core presence assertion, and the exemptNote core clause. `core/` is now required like everything else and covered by measurement (127→894 files; a `core/*.tsx` web doesn't reach is now caught by measurement, not a hand-model). Kept the core-specific remediation clause. - Finding 2: the reference (`tsc -b`) path skipped the non-inertness check — a `tsc -b --noCheck` build gated nothing while the guard stayed green. Turned `validateRunsTscBuild` into `tscBuildStatus` (ok/neutered/none); a neutered `tsc -b` now hard-fails, matching the typecheck-script path. Factored the disabling-flag predicate (`isDisablingFlag`) so both paths share it. - Nit 3: `clientTsconfigReferences` now strips block comments too (every other tsconfig in the repo uses `/* */`). - Nit 5: README/AGENTS wiring clause covers web's `tsc -b` (not just the `typecheck` script), and core is described as measured, not exempt. Nit 4 resolves itself: EXEMPT is empty and the exemptNote/ternary now collapse cleanly. Nit 6 (tsc -b bound to a specific tsconfig) left as recorded.

Fixed at the measurement layer: projectFiles now expands a solution config (`{"files":[], "references":[…]}` — lists nothing under --listFilesOnly) to its references and measures those recursively, so a `tsc -b` project is measured no matter which path harvests it. Generalized the references reader (tsconfigReferences(path)). Verified web with `typecheck: "tsc -b"` now passes. Dropped the stale "web … is out of scope" JSDoc clause. - Nit 2: a `core/**/__tests__/**` miss now points at `tsconfig.test.json` (its actual owner), not `tsconfig.app.json`. - Nit 4: AGENTS.md's one-line summary now mentions the non-client (`core/`, `test-servers/src`) coverage, matching the detailed bullet. Nit 3 (EXEMPT empty, dormant stale-key check) left as the intended escape hatch.

Factored a shared `resolveLeafProjects` (a solution → its real leaf projects, cached rawProjectFiles) used by BOTH coverage (`projectFiles`) and a shared `checkingLeaves` disable-check, so a `noCheck` in a referenced project is now caught on either path. Verified: `typecheck: "tsc -b"` + `noCheck` in tsconfig.app.json now hard-fails (was green). Caching also cut the guard from ~20s to ~11s. - Nit 2: directory-form references (`{ "path": "./packages/a" }`) now resolve to `<dir>/tsconfig.json`, so a nested-solution dir reference is expanded. - Nit 3: reworded the empty-listFiles comment (it's "solution config OR errored config", both of which the reference expansion handles). - Nit 4: script header notes a `tsc -b` solution is reduced to its references on either enrollment path.

Now tracks visited leaves in a Set and skips an already-seen leaf entirely. Verified a duplicate harvested project yields one line, not two. - Nit 3 (record-completeness): noted in AGENTS that the one tier the guard structurally can't see — a per-file `// @ts-nocheck` — is owned by `@typescript-eslint/ban-ts-comment` across lint:core/lint:shared/each client. Nit 2 (the ~11s perf claim isn't reproducible on a CI-class runner) and nit 4 (hybrid-solution / composite boundaries, both tsc-rejected → unreachable) left as recorded.

Behavior when run directly is unchanged (894 files). - Added table-driven tests (node's built-in `node --test`; the root has no vitest harness by design) for the shared lib (`tokenize`, `reachableScripts` incl. pre/post hooks, `rootRunsClientValidate` across cd/--prefix/quoted/ prefix-sibling/`validate:fast`, `rootReachesScript`) and the guard's parsers (`isRequiredSource`, `isTsc`, `isDisablingFlag`, `typecheckProjects`, `tscBuildStatus`) — one case per rule a review round found (r7/r10/r13/r15/ r16/r17/r18/r19/r20/r25). 12 tests. Wired `test:scripts` into `validate`. - Nit 2: a `scripts/*.ts` miss now gets a scripts-specific remediation (keep it `.mjs`, or give `scripts/` its own tsconfig project). - Documented the guard's test suite in AGENTS.md.

So dropping it from validate, or renaming a test to `*.spec.mjs`/`*.test.mts` (which node --test silently skips), now hard-fails. Verified both. - Nit 2: extracted a pure `parseTsconfigReferences(raw)` from tsconfigReferences and table-tested the JSONC tolerance (block/line comments, trailing comma, no references, malformed, no path) — the r17/r26 rules had no cover. - Nit 3: added `-b`/`--build`/bare-`tsc -b` and explicit `--project` cases to typecheckProjects's test so its title matches its table. - Nit 4: rewrote the rootRunsClientValidate test to put `cmd` in a script reached from validate, and added the reachability cases (an orphan cd-validate must NOT count; validate:tui indirection must) — the r5 property. - Nit 5: added test:scripts to AGENTS's validate ordering + the README table. 15 guard tests now.

The glob half read `rootPkg.scripts["test:scripts"]` literally while the wiring half two lines above used `reachableScripts`, so a delegating `test:scripts` (`npm run test:scripts:lib && npm run test:scripts:guard`) — which genuinely runs all 15 tests — reported every tracked test file as "not matched by the glob", advising a rename the files already satisfy. Now harvested across every script reachable FROM `test:scripts`, the same fix round 6 applied to the `typecheck` harvest; `pretest:scripts` counts for free. 2. `globToRegExp` escaped `{`/`}` as literals and left `?` as a regex quantifier, both divergent from `node --test`'s glob. `*.{test,spec}.mjs` is the natural widening here (the guard's own file scan already treats a `.spec.` file as a test) and false-failed; `?` silently meant "optional previous char" and threw outright when segment-leading. Adds `?` → `[^/]` and a brace-alternation pass, with an unbalanced brace falling back to a literal. Nit 3: `resolveLeafProjects`'s two path-resolution rules (the r26 directory-form reference, and refs resolving against the referring config's dir) extracted as `projectConfigFile`/`refToProject` so they are one-row tables like the other parsers, rather than untestable behind a `tsc` spawn. Nit 4: AGENTS.md + README document that the guard now enforces `test:scripts` on three axes (wired, non-empty, glob-covered). Verified: probes C and D exit 0; probe B (rename to `*.spec.mjs`) still caught; `test:scripts` 18/18; `verify:typecheck-coverage` OK 894 files; `verify:format-coverage` OK 919; `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-32 — measure globs with node's own matcher Round-32 review; both findings point at deleting code. 1. `globToRegExp` hand-modeled `node --test`'s glob and was still one form short — character classes (`*[.]test.mjs`, `*.test.[mc]js`) hit the escape set and became literals, so the guard false-failed on files node genuinely runs. Replaced the whole translator (and its brace balance pre-scan) with node's `path.matchesGlob` — 22.5.0+, and the repo floor is >=22.19.0. Same *measure, don't model* move round 25 made when it deleted `isExemptCoreFile` in favor of measuring web's projects; being exact for every form node accepts is the point, since node's matcher is the thing being modeled. 2. The round-31 glob harvest was inline in `main()`, so mutation-reverting it to the literal single-script read left the suite green — the commit's headline fix was its one untested change. Extracted as `testScriptGlobs`, with rows for the direct form, the delegating form (both child globs, not `npm`/`run`/`<name>`), a `pretest:scripts` hook, and an unreachable script contributing nothing. Nit 3: `resolveLeafProjects`' JSDoc moved back onto it (the extraction left it stranded above `projectConfigFile`, which had two stacked doc blocks). Nit 4a: a `test:scripts` naming no path/glob harvested nothing, and `.some()` over an empty list blamed every test file with unfollowable advice. Now one explicit message naming the real problem. Verified: probes for the direct, delegating, brace, `[.]` and `[mc]` forms all exit 0 (the last two were false failures before); probe B (rename to `*.spec.mjs`) still caught; bare `node --test` reports the new single message; `test:scripts` 18/18; `verify:typecheck-coverage` OK 894; `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-33 — scope the glob harvest to `node --test` segments 1. False pass. `testScriptGlobs` kept every non-flag token from every reachable script, so a glob belonging to a NEIGHBOURING command was attributed to the test runner — and since `.some()` needs only one glob to match, a broader one suppressed a real miss rather than adding an inert pattern. A `pretest:scripts` of `prettier --check "scripts/**/*.mjs"` (reachable via the pre-hook round 31 added) was enough: the probe-B rename to `*.spec.mjs` then passed while `node --test` silently ran 12 of 18 tests. Now scoped per command segment to the ones invoking `--test`, exactly as `typecheckProjects` gates on `tokens.some(isTsc)`. The JSDoc paragraph claiming a surplus token can't suppress a miss is corrected — it was false. 2. The gate-integrity block is extracted as `testScriptProblems(scripts, testFiles)`, pure and outside `main()`. The nit-4a branch added last round was the third consecutive commit whose newest branch sat outside the test seam and mutation-survived; extracting the block ends the pattern rather than pinning one more condition from the outside. Verified. The finding-1 probe (prettier pre-hook + `*.spec.mjs` rename) now exits 1 where it exited 0; the hook alone still exits 0. Mutation testing over the whole helper — empty-harvest branch to `if (false)`, segment gate removed, wiring axis removed, non-empty axis removed, segment split removed, `reachableScripts` to `Object.keys`, `matchesTestGlob` to equality — kills 7/7, including the branch that survived the last three rounds. `test:scripts` 21/21 · `verify:typecheck-coverage` OK 894 · `verify:format-coverage` OK 919 · `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-34 — harvest only positional args; normalize `./` Both findings are the axis round 33 fixed, one level in. 1. False pass. The segment gate stopped a neighbouring COMMAND's glob, but within a kept segment the filter was still "any non-flag token", so a glob-valued flag's VALUE was harvested as a positional arg. `--test-coverage-include "scripts/**/*.mjs"` is broader than the test glob and matches a renamed `*.spec.mjs`, so it vouched for the very file the runner skips — and it isn't hypothetical: `scripts/` sits outside the ≥90 coverage gate, so that flag is the obvious next thing added here. Tokens preceded by a value-taking `--test-*` flag are now dropped. 2. False failure. `./scripts/**/*.test.mjs` — which `node --test` accepts, and the common npm-script idiom — matched nothing, because `git ls-files` emits no `./`. Both files were then blamed for a rename that never happened, the unfollowable-remediation shape fixed for the bare-runner case last round. A leading `./` is normalized off, as `rootRunsClientValidate` already does. Nit 4: the gate-integrity footer's typecheck-wiring advice is now conditioned on at least one issue being about the typecheck wiring — a `test:scripts` failure carries its own per-line remediation, and appending `--noCheck`/`tsc -b` advice under a renamed-test-file message sends the reader after the wrong thing. Verified. The coverage-include probe with the rename now exits 1 where it exited 0, and exits 0 without the rename; the `./` probe exits 0 where it exited 1; a `test:scripts`-only failure no longer prints the typecheck footer. Mutation sweep 9/9 killed, including both new rules. `test:scripts` 22/22 · `verify:typecheck-coverage` OK 894 · `verify:format-coverage` OK 919 · `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-35 — fourth axis: flags that narrow the run 1. False pass on a new axis. The three axes ask whether the tests are run, whether there are any, and whether the runner is told about each — none asks what it then DOES with them. `--test-shard 1/2` keeps every glob intact and executes 6 of 22 tests, exiting 0, with the guard green; `--test-only` runs 2, as does a non-matching `--test-name-pattern`. This is `--noCheck` for the test runner, one domain over. Adds `NARROWING_TEST_FLAGS` and a fourth axis in `testScriptProblems`. Three of those flags were already in `VALUE_TAKING_TEST_FLAGS` — the guard knew them well enough to drop their values but not that they shrink the run. Both `--flag value` and `--flag=value` report as the bare flag name. 2. The footer conditioning added last round was itself inside `main()` — the pattern the same commit's comment documented, recurring in the commit that documented it. Extracted as `integrityAdvice(problems, nonTypecheck)`. Doing that fixes nit 3 in the same move: the old condition keyed off `testScriptIssues` specifically, so it covered one of three non-typecheck categories. A sibling-vouch failure ("the root validate no longer runs verify:format-coverage") and client-enrollment problems still got `--noCheck`/`tsc -b` advice about a typecheck pass they have nothing to do with. All three sets are now excluded. Verified. `--test-shard 1/2`, `--test-only` and `--test-name-pattern zzz` each now exit 1 naming the flag, while node runs 6/2/2 of 22. A sibling-vouch failure no longer prints the typecheck footer. Mutation sweep 12/12 killed, including all three new rules and the branch this commit replaces. `test:scripts` 24/24 · `verify:typecheck-coverage` OK 894 · `verify:format-coverage` OK 919 · `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-36 — discover test files by content, not name 1. False pass on the axis underneath the other four. The required test-file set was built with the same name pattern the `test:scripts` glob uses, so a rename escaping BOTH was invisible: the file left `testFiles` entirely, so nothing asked whether the runner was told about it, and the survivor satisfied the non-empty axis. A dot→hyphen slip (`npm-scripts.test.mjs` → `npm-scripts-test.mjs`) dropped 6 of 24 tests with every gate green — and the file that stops running is the one pinning the r16 prefix-sibling and r20 tail anchors, the series' two other false passes. Round 30 fixed "renamed to a form the glob misses" by broadening the name pattern; a fifth name pattern only moves the boundary again. `node --test` decides what a test is by whether it registers tests, so `isScriptsTestFile` reads that instead — the same measure-don't-model move as r25 and r32. It also covers what no name pattern can: a NEW test file added under a name the glob misses, never run and never noticed. Nit 2: `enrollmentProblems` no longer suppresses the footer. "declares no `typecheck` script …" IS about the typecheck pass and the footer's first clause is its canonical fix; excluding it lost the advice for the r15 rename scenario. The criterion is "is this about the typecheck pass at all", not "does it carry per-line advice" — several typecheck problems carry their own and still want the footer. JSDoc corrected accordingly. Nit 3: the complementary-shard boundary (`1/2` + `2/2` across two reachable scripts genuinely runs everything, and is flagged anyway) recorded on the helper, alongside the guard's other documented boundaries. Nit 4: the three `--test-coverage-{lines,branches,functions}` thresholds added to VALUE_TAKING_TEST_FLAGS. Their values are numeric and so inert rather than suppressing, but model completeness is cheaper than re-deriving that later. Verified. The hyphen rename now exits 1 naming the file; the `.spec.mjs` rename is still caught; an enrollment failure prints the footer again; the guard is unchanged at 894 files OK (exactly the 2 tracked test files reference `node:test`, none of the other 12 `scripts/` files do).

False failure. The predicate matched a bare `node:test` mention, so a shared helper importing the runner's `mock` API — registering no tests — was enrolled as a required test file and told to rename itself to `*.test.mjs`, which would only make node run an empty file. `scripts/lib/` is already the repo's shared-helper location, so this is the plausible next file there. Tightened to node's actual criterion: an import/require OF `node:test` AND a test registration. 2. Regression. `readFileSync` was passed as an argument, so it ran for every tracked `scripts/` file before the predicate's extension gate could reject it — a file in the index but not the worktree (`rm` without `git rm`) took the guard down with a raw ENOENT stack, aborting phase 1 before any real finding printed. Discovery did no reads at all before round 36. Extension is now gated first and the read wrapped: an unreadable tracked file warns and is skipped, the round-6 precedent where a failed `tsc` echoes its diagnostic instead of dying. Verified: the mock-helper probe exits 0; the tracked-but-deleted probe exits 0 with a one-line skip warning instead of a stack; the dot→hyphen rename is still caught. Mutation sweep over the predicate 3/3 (import form, registration, extension). `test:scripts` 25/25 · `verify:typecheck-coverage` OK 894 · `verify:format-coverage` OK 919 · `npm run ci` green.

* fix(core): start OAuth on a modern/auto-era connect (#1805) The SDK's `server/discover` negotiation probe runs before anything else on `protocolEra: "auto" | "modern"`, and its classifier reports whatever the transport threw as `SdkError(ERA_NEGOTIATION_FAILED)` with the real error moved to `data.cause`. That buried both connect-time auth signals: the remote path's `AuthRecoveryRequiredError` (matched with `instanceof`, and carrying the authorization URL) and a direct transport's `AuthChallengeError`. An OAuth-protected server that authorized fine on the legacy era instead produced a dead-end "Version negotiation probe failed" — no redirect, and the connection status flipped to `error` despite `isConnectAuthRecoveryError` existing to prevent exactly that. - `findNestedAuthError()` walks `cause` / `data.cause` for either typed error. Not gated on the SDK's error code or message, so it survives rewording. - `connect()` unwraps the rejection at the earliest point, ahead of `withDirectAuthRecovery` (whose `isAuthChallengeError` check is shallow), the outer status guard, and every client's connect error handling — so web, CLI, and TUI are all fixed without a client-side change. - On the direct path, enable `interceptAuthChallenges` for the probing eras even with no stored tokens. Without an authProvider the 401 reaches the SDK as a raw `SdkHttpError`, and the classifier ignores the HTTP status (it only looks for a JSON-RPC error body) — so pin mode rethrew it with the 401 discarded entirely, no status and not even a cause for the walk to find. Verified against a live dual-era server that answers 401 on both `initialize` and `server/discover`: `auto` and `modern` now reject with `AuthRecoveryRequiredError` carrying a real authorization URL. Each half of the fix is load-bearing — reverting either fails the new integration tests.

On a "satisfied" outcome the recovery runs a complete nested connect() via reconnectAfterAuthRecovery(), so the retry leg re-awaited the already-rejected promise and rejected a connect() whose client was in fact connected. Short-circuit the retry when already connected, and skip the post-connect block the nested connect already ran (a duplicate `connect` event re-triggers every list-state manager's refresh). - Document the accepted 403 side effect of enabling interceptAuthChallenges with no stored tokens, and why every `{ pin }` counts as probing. - Replace the private-method double cast in the era-probe test with an observable assertion on the transport options, and split the non-auth failure case per era instead of a message alternation that passed either way.

The `attempt >= 1` guard is per-call and a satisfied outcome recovers via a nested connect() with a fresh counter, so a server that keeps rejecting freshly refreshed tokens recursed without bound. Counted across the nesting boundary, capped at 3. - Strengthen the regression test (server info populated by the nested connect, no duplicate statusChange) and add the two missing cases: a failed reconnect still rejects, and the recursion bound terminates. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016S7h83UKNQ7kvSiFDNksCt * test(core): cover the recovery teardown branch; fix a duplicated case Third-pass review findings on #1809, both about tests added in the previous commit: - The retry leg's teardown error had no coverage, so a regression to the old status fall-through would have stayed green. Covered deterministically: the nested connect dispatches `connect` after setting "connected", so closing the live transport from that listener flips the status before the retry leg runs. Asserts the error identity, which is the point of the change. - "still rejects when the reconnect underneath the recovery fails" used a challenging transport for every connect, so it walked the same bounded chain as the recursion-bound test rather than covering a non-auth reconnect failure, and its comment claimed an "error" status the auth path never reaches. Now fails the reconnect with a plain error and asserts both.

…st (#1808) (#1810) * fix(auth): offer explicit re-authorize when callback state is lost (#1808) A `/oauth/callback` that arrives with no recorded SEP-2352 discovery state made the SDK throw `AuthorizationServerMismatchError` and the Inspector dead-ended, surfacing the raw SDK text with no path forward. The SDK folds two very different failures into that one error class, so `core/auth/issuerBinding.ts` classifies them structurally: a recoverable "lost authorization state" (the SDK puts prose, not an issuer URL, in the `recordedIssuer` slot) versus a genuine cross-AS `issuer_mismatch`. Only the first gets a recovery affordance. Web: the callback failure now raises a dedicated banner ("Authorization state was lost" / "Authorize again") whose action clears the stale OAuth state for that server and starts a fresh authorization. A genuine mismatch stays a red, non-dismissible security notification with both issuers named and no one-click retry. Node runners (CLI/TUI): the same classification rewrites the callback rejection into the shared actionable copy instead of the SDK text. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016S7h83UKNQ7kvSiFDNksCt * fix(auth): detect the SDK mismatch error via isInstance (#1808) The callback-leg classifier gated on `err.mcpBrand`, but the SDK declares that brand in a `static {}` block, so it lives on the constructor and is never reachable from an instance. The predicate always returned false, so `findIssuerBindingFailure()` never matched and the #1808 recovery banner was inert in production — the callback dead-ended exactly as before. Use the SDK's own `AuthorizationServerMismatchError.isInstance()`, which is cross-copy safe by construction (it consults a `Symbol.for()`-keyed brand set), with a `name` fallback for a serialization boundary. Correct the module doc, which cited cross-bundle safety as the reason to avoid `instanceof` — the very thing the SDK's branded `hasInstance` provides. Every fixture now constructs a real `AuthorizationServerMismatchError` instead of a hand-rolled object with an own `mcpBrand`, which is why a green `npm run ci` hid this. Adds a test pinning the brand's placement so the feature cannot silently go inert again. Review follow-ups: drop the unused `isLostAuthorizationStateError`, remove the duplicated banner title default, resolve the banner title/action label where the banner is raised, keep the clear-failure notification open, and bound remote-supplied issuers in user-facing copy.

* docs: refresh V2 board Status option IDs in AGENTS.md (#1823) `V2 Go Live` (`b3a6966e`) was added to the Status field via the web UI on 2026-07-27 for the go-live phases (#1804) and was not in the table; the `SDK V2 + New Spec` row it replaced in position (`1bbb6f57`) had already been removed, so following the table failed with "option Id does not belong to the field". Record the current five options, note that adding the column via the web UI left the other four IDs untouched (evidence the UI path is safe, unlike the GraphQL full-replace hazard documented below it), and list every removed column's dead ID in one place. Also add the missing recipe for moving a card that is already on the board: the existing recipes only cover `item-add` for a new item, leaving no copy-paste path for looking an existing card's item id up by issue number.

Add it. Also fold in two adjacent fixes: the "In review" casing left behind two lines from the "In progress" → "In Progress" fix (labels are matched exactly when re-fetching ids by name), and a note that --limit must stay above the board's item count, since exceeding it truncates silently and surfaces as an opaque node-resolution error from item-edit.

The two recipes above it already carry their context as in-block comments; match that.

…1814) * fix: wait for the TUI to exit before removing its temp dir (#1801) `done()` sent SIGTERM and then immediately `rmSync`'d the work dir, which doubles as the TUI's HOME. Nothing waited for the child, so the Ink process could still be writing into the dir while rmSync walked it — a file landing after a directory was read but before it was removed surfaces as ENOTEMPTY on macOS, failing `smoke:tui` after a successful render. Removal now happens only once the child's `exit` event fires: SIGTERM, then SIGKILL after SMOKE_TUI_EXIT_GRACE_MS (default 5s), then clean up regardless after twice that. The crash-before-render path short-circuits via a `childExited` flag set by the pre-registered exit handler. cleanup() also warns instead of throwing, so a leftover temp dir can never fail a passing smoke. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MvKF2mqi4hoQSUqQpZXNTq * fix: wait on close, not exit, so spawn failure resolves instantly (review #1814) A failed spawn emits `error` + `close` and never `exit`, so the previous `child.once("exit")` wait never fired on that path: done() sent SIGTERM to a process that never existed and resolved only via the give-up timer — 10s at the default grace, with a warning blaming a SIGTERM the child never received. Waiting on `close` covers both normal termination and spawn failure, and additionally guarantees the stdio pipes are drained. The short-circuit gate moves with it, `childExited` → `childClosed`: keying it on `exit` would have skipped the drain on the crash-before-render path, which is exactly where the quoted output matters. Messages that quote that output are now thunks rendered in finish(), after the drain, instead of being sliced at call time. SIGTERM is now sent only to a child that is still running, since on both the crash and spawn-failure paths there is nothing left to signal. finish() also gets a `finished` guard so its single-entry invariant is local rather than inferred from process.exit() being synchronous. Measured, spawn failure (grace shortened to 500ms): 1.04s + spurious warning before, 0.02s and silent after. Crash-before-render now prints the child's stderr detail line that the pre-drain slice could truncate. Happy path 3x, timeout path, and full `npm run smoke` + `npm run validate` all green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MvKF2mqi4hoQSUqQpZXNTq * fix: bound the drain, and make the give-up warning true (review #1814 r2) Three follow-ons from the second review pass: The give-up warning still said the TUI "did not exit within Xms of SIGTERM", but after switching the wait to `close` neither clause is reliably true — the timer's most plausible trigger is now a child that has already exited, and on the crash and spawn-failure paths no SIGTERM is sent at all. That is the same defect this PR fixed one round ago (a warning naming a signal never sent), so the deadline is now re-armed with a message describing what is actually being awaited. `close` is bounded by whoever holds the stdio pipes, which can outlive the direct child: a descendant that inherited them keeps it pending. That is the one real cost of `exit` → `close`, and it is moot only because the TUI spawns nothing at boot — a reason that lives entirely outside this file. Once `exit` has fired the deadline drops to DRAIN_MS, keeping the drain guarantee without inheriting an unrelated process's lifetime. Measured against a grandchild holding the pipes for 3s: 0.54s and an accurate warning, instead of 3s. The quoted output is sliced from the tail rather than the head. The thunk added last round exists to capture bytes that arrive late, which a head slice then discards as soon as output exceeds 800 chars — and on the timeout path the last frame is what diagnoses a stuck render, not the first. Verified: a 2KB stderr crash now reports its final line. The sibling scripts keep `slice(0, 800)`; changing them is a deliberate sweep, not a drive-by here. Also corrected the cleanup() comment — the wait lives in done(), and it is for `close`, not `exit`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MvKF2mqi4hoQSUqQpZXNTq * docs: correct the cleanup() and DRAIN_MS comments; tail-slice cleanly (review #1814 r3) The cleanup() comment claimed its warning "should not fire now that removal waits for close" — true only of the normal path. Both give-up branches call finish() without close, and those are precisely the states where something may still hold the dir, so the warning is expected there. Same defect class as the two warnings already fixed in this PR (a message asserting what the code no longer guarantees), relocated into a comment. The DRAIN_MS comment explained why the cap exists but not what it costs: on that path the work dir is removed while a descendant holding HOME=work may still be writing to it — #1801's race, re-entered deliberately. That is only acceptable because cleanup() warns instead of throwing, so record the two as load-bearing for each other where the constant is defined. Tail-slicing an Ink stream can begin mid-CSI-sequence, leading a diagnostic with an escape-code fragment that mangles the line after it. outputTail() drops through the first newline when the output was actually truncated, and returns short output untouched.

… wording (#1811) (#1812) Closes #1811 Four README links pointed at files that don't exist on `v2/main`, and the launcher README described catalog seeding as one behavior when it is two. - `docs/mcp-server-configuration.md` — written fresh for v2 (the v1.5 file predates the `--catalog`/`--config` split) - `docs/launcher-config-consolidation-plan.md` — restored from `v1.5/main`, path drift corrected, v2 notes appended - `docs/images/tui-screenshot.png` — regenerated against the current TUI - launcher README seeding wording — split into the two real behaviors (web seeds two sample servers; cli/tui seed empty) Review across three rounds also corrected several claims verified against source: the `--` separator is inverted between web and cli, a cli target placed after a flag is silently discarded, `--server` is a no-op on web and an unknown-option error on tui, the `MCP_CATALOG_PATH` ad-hoc guard is cli-only, and the conflict matrix diverges on both `--header` and `--transport stdio`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01Txmv2qqv3yeKgRzoqXytzD

Phase 4 of the v2 go-live runbook (#1804 §5). `main` becomes the v2 tree while keeping its own history: this is a true merge recording `v2/main` as a second parent, not a reset, so no force-push is needed and the default branch's history and PR trail survive intact. Mechanically: `-s ours` to take no tree from the merge, then the index is replaced wholesale with `v2/main`'s. `git diff HEAD origin/v2/main` is empty afterwards. Note the runbook's command needed one addition — `main` and `v2/main` have genuinely unrelated histories (different root commits, no merge base), so `--allow-unrelated-histories` is required or the merge refuses outright. All 125 open PRs previously targeting `main` were re-pointed at `v1/main` first, so none of them are stranded against a tree that no longer exists.
