e31a20eec7 test(proxy): isolate proxy env per file; word the guard failure by candidate source
Addresses review round 7 on #2099 (three suppressed comments).

- Proxy variables are now cleared for the WHOLE of `transport.test.ts` and
  `cli.test.ts`, not just around the proxy tests. Measured: undici's
  `EnvHttpProxyAgent` captures its proxy URLs when it is CONSTRUCTED and re-reads
  only NO_PROXY per request, so with the process-wide memo, any earlier test that
  connects on a machine with an ambient proxy would pin the agent to it and a
  later test setting HTTP_PROXY would be talking to an agent that is not
  listening. Clearing up front means nothing can build the singleton before the
  proxy tests do, and restoring only in the file-level afterAll means the memo
  cannot be left bound to a closed test proxy.

  Both suites verified green under a hostile ambient env
  (`HTTP_PROXY`/`http_proxy`/`HTTPS_PROXY` pointed at a dead port). In fairness
  this is hardening rather than a fixed failure: the concrete cross-test break
  did not reproduce with the current test order — but it depends on test order
  and on the developer's environment, which is exactly what this removes.

- The guard's failure message said a package "is declared external but was
  inlined" even for a candidate that came only from the root dependencies —
  i.e. #2067's own shape, where the missing `external` entry IS the bug, so the
  message contradicted the config it was asking the reader to check. It now
  words the failure by candidate source, and says to add the entry.

The capture-at-construction behavior is documented on `createProxyFetch`, since
it is the reason the suites are structured this way.

96f96aad41 fix(proxy): preserve fetch semantics through the proxy adapter
Addresses review round 4 on #2099 — three posted comments and three suppressed
ones, all valid.

- A rebuilt Response reported `url: ""`, `redirected: false`, and
  `type: "default"` even after undici followed a redirect: a fetch-contract
  regression visible only to proxy users, and one `core/auth/endpointOverrides.ts`
  explicitly guards against by declining to rebuild at all. This adapter has no
  such choice — the response arrives from the wrong realm — so it now reinstates
  the three with `defineProperty`.

- Normalizing a `Request` input dropped every option the Request itself carried
  beyond method/headers/body/signal. Most visibly `redirect`: a
  `new Request(url, { redirect: "manual" })` started following redirects instead
  of surfacing them. All of them are now carried through, with an explicit
  `init` still winning per the fetch contract.

  Both are covered by tests driving a real redirect through a real proxy, and
  both were confirmed to fail without the fix.

- `@modelcontextprotocol/ext-apps` was added only to the CLI's `external` list.
  AGENTS.md requires every root-declared runtime dependency in all three, since
  which client reaches it is a function of what `core/` imports rather than of
  the client's own code. Added to the web runner and TUI lists too.

- The `BUNDLED_CLIENTS` test compared the hard-coded list against a hard-coded
  copy of itself, so a new tsup-bundled client would have left it green while
  going unchecked. It now discovers clients from disk (a client is tsup-bundled
  iff it ships a tsup config) and compares. Verified it fails when a stub client
  is added.

- AGENTS.md's project tree still described `core/mcp/node/` as only the stdio
  transport factory; it now carries `proxyFetch.ts` and its role.

dbe95e58ed fix(guard): derive must-not-bundle candidates independently of external
Addresses the suppressed review comment on #2099, which was the sharpest of the
three rounds: the guard stopped looking at a package the moment its `external`
entry was removed — so deleting `"undici"` from the web config would have made
the pre-fix bundle pass. That is self-referential, and #2067 was precisely a
MISSING declaration, so the guard covered its regression but not the bug.

Candidates are now the union of two independently-derived lists: each client's
`external` array, and the root manifest's `dependencies` — root-declared by
rule, reached through `core/`, and required to be external in every client
bundle. Removing a package from an `external` list can no longer remove it from
scrutiny.

That immediately surfaced one latent instance of the same rule violation:
`@modelcontextprotocol/ext-apps` is root-declared and reached through
`core/mcp/apps.ts`, but was absent from the CLI's `external` list and was being
inlined into `index.js` — dragging the transitive v1 SDK and zod-to-json-schema
in with it. It is ESM, so it was not failing the way `undici` did; what it
violated was the rule. Adding it drops the CLI bundle from 590KB to 518KB.

It is also a real example of the shape the previous revision could not see: it
was inlined into the entry, emitting no `<pkg>-HASH.js` chunk at all.

2f83549bc3 test(proxy): isolate proxy env per suite; fail the bundle guard closed
Addresses review round 2 on #2099.

- The /api/fetch proxy test set only uppercase HTTP_PROXY, so an ambient
  lowercase `http_proxy` (which undici's EnvHttpProxyAgent prefers) or a NO_PROXY
  could route the request elsewhere and fail the assertion. All six proxy vars
  are now saved and cleared for the whole /api/fetch suite and restored in
  afterAll — suite-level rather than per-test because the agent is memoized
  process-wide once built. Verified the test still passes under a deliberately
  hostile ambient env (`http_proxy=http://127.0.0.1:9 NO_PROXY='*'`).

- `verify:bundle-externals` reported success when `parseExternals` returned
  nothing, so an ordinary tsup refactor — hoisting the array to a constant, or a
  line break after `external:` — would silently disable the guard. It now fails
  closed: every bundled client has externals, so "none parsed" means the parser
  lost track of the config. Verified against exactly that refactor. The
  per-client verdict moved into a pure `evaluateClient()` so all three failure
  modes are unit-tested, and the failure epilogue is now printed only for a real
  inlining, since "add the package to `external`" is the wrong instruction for
  the other two.

9a084f49e5 fix(proxy): proxy /api/fetch, and detect entry-inlined externals
Addresses the Copilot review on #2099.

- `/api/fetch` used the bare global `fetch`. That route is the browser's only
  way out to the network — the web client's `environment.fetch` is
  `createRemoteFetch()`, which forwards OAuth discovery and token requests
  there — so a corporate-proxy user could connect to a server but never
  authorize against it, and the PR's "OAuth is proxied now" claim held for the
  CLI and TUI but not for web. It now uses the same proxy-aware base fetch, with
  an integration test driving a real forwarding proxy (confirmed failing without
  the fix).

- `verify:bundle-externals` only recognized an inlining that produced a
  `<pkg>-HASH.js` chunk. A *statically* imported package is folded into
  `index.js` and emits no chunk, so it would have passed. Detection now keys off
  esbuild's `// <path>` module banners, covering both shapes. Because that
  depends on unminified output, a bundle with no banners now fails as such
  rather than reporting clean — enabling `minify` cannot silently retire the
  check. Tests cover the entry-inlined case, the same-prefix case
  (`undici-types` must not read as `undici`), and the no-banner case.

- The pre-push pipeline summaries in AGENTS.md, README.md, and
  .github/copilot-instructions.md still described `verify:build-gate → smoke`
  and omitted the new gate.

d90a955164 fix(proxy): route through undici's own fetch and keep undici external
Corporate-proxy users could not connect to any remote MCP server from v2.
Two independent defects, both reported in #2067.

1. The web and TUI bundles inlined undici. It was declared in the root and
   `clients/cli` manifests but named in no client's tsup `external` list, and
   tsup auto-externalizes only what the *nearest* manifest declares — so
   esbuild inlined 1.05MB of it into `clients/{web,tui}/build/`. undici is
   CommonJS, so the emitted chunk's `require("assert")` hit esbuild's ESM
   `__require` shim and threw `Dynamic require of "assert" is not supported`.
   The rejected `import()` surfaced as "the `undici` package is not available",
   telling users to install a package that was already present — and could not
   have helped, because the specifier had been rewritten to a relative chunk at
   build time.

2. `withProxyDispatcher` injected a *userland* undici `EnvHttpProxyAgent` into
   Node's *built-in* fetch. That couples two different copies of undici at the
   dispatcher handler interface, which is not stable across majors: Node 22
   embeds undici 6, Node 24 embeds 7, Node 26 embeds 8. A userland undici 8
   agent handed a built-in undici 7 handler is rejected with
   `fetch failed: invalid onRequestStart method`, and the request never leaves
   the process. So fixing the bundling alone would only have converted the
   web/TUI failure into the CLI's.

Both halves of the pair now come from userland undici — its `fetch` and its
`EnvHttpProxyAgent` — which keeps the handler inside one copy and works
unchanged from the Node 22.19 engine floor through Node 26. Deleting the
wrapper in favor of Node's native `NODE_USE_ENV_PROXY` was not an option:
measured, it is unsupported on 22.19 (the floor) and only lands mid-22.x.

Because undici's `Response` is a different class from `globalThis.Response`,
the proxied fetch re-wraps each response as a genuine global `Response`,
streaming preserved. Without that, `res instanceof Response` is false for
callers that test it — including the SDK's OAuth error formatter, which would
degrade every message to `Raw body: [object Response]`.

The proxy now sits at the bottom of the fetch stack (`environment.fetch` for
the Node clients, and the `createTransportNode` default for the web backend,
its one caller that supplies no `fetchFn`) rather than wrapping the transport's
fetch. Proxying means *substituting* the fetch, not decorating one, so wrapping
a supplied `fetchFn` would discard it; installing it underneath lets
InspectorClient's own wrappers compose over it. A side effect worth having:
OAuth discovery and token requests go through `environment.fetch` too, and were
never proxied before.

Guarding it:

- `undici` is added to all three tsup `external` lists and removed from
  `clients/cli/package.json`, so it is root-declared only, per the placement
  rule in AGENTS.md. The two installs had already drifted (root 8.5.0 vs cli
  8.9.0).
- New `npm run verify:bundle-externals` fails if any package a client declares
  external was inlined into that client's bundle anyway. It reads the *built
  output*, not the config — those two disagreed for four releases — and derives
  what to check from each client's own `external` array, so a newly
  externalized package is covered without editing the guard. Verified against
  the real pre-fix artifact, which it flags.
- The proxy tests now drive a real forwarding proxy rather than a mock. That
  matters: defect 2 was a runtime interface mismatch, which no mock can catch
  because no mock ever dispatches.

AGENTS.md's must-not-bundle rule (added by #2082) is extended with why undici
slipped past it, and notes the `node -e` trap — probing the bundled chunk with
`node -e` falsely succeeds, because it exposes a global `require` that
satisfies esbuild's guard.

Closes #2067

6b4bf68b8b fix(scripts): observe the final polling interval before declaring a timeout
Copilot's suppressed round-3 comment is right. The attempt-counted loop read
the output and then slept, so nothing ever observed the last interval: an
announcement arriving at 29.9s of a 30s budget was reported as a timeout, and
a spawn error or early exit landing in that window was misattributed the same
way. Inherited from the original smoke, but wrong either way.

Replace it with a deadline loop that re-reads state after every wait, the last
one included, and clamp the final wait to the deadline so the budget is a real
bound rather than one poll longer.

The regression test sets pollMs === timeoutMs, which makes the distinction
deterministic rather than a race: the attempt-counted loop gets exactly one
check, at t≈0 before the child has finished starting, then throws; the deadline
loop re-reads after the wait and sees the announcement. The child announces
immediately, ~2s inside the window, so a loaded runner can't flip it. Verified
both directions — the test fails against the old loop and passes against the
new one — and `npm run test:scripts` was repeated to confirm it is stable under
the full 116-test parallel run (an earlier margin-based version of this test
was not).

9cade95fd0 test(scripts): kill the probe child on every path; document the helper
Two review findings from round 2, both correct.

1. The regression suite killed its child only after the assertions. If
   `assert.rejects` or either assertion failed, execution never reached the
   kill, leaving a 60-second child attached to the runner — a suite guarding a
   process leak would leak one itself, precisely on the run where the
   regression had come back. Teardown is now registered from `onSpawn` via
   `t.after`, so it runs on every path out of every case. That is the helper's
   own ownership rule applied to the tests; killing an already-exited child is
   a no-op, so the early-exit cases pay nothing for it.

2. Document the new shared helper, per the maintenance rules. AGENTS.md's
   scripts/lib tree entry now carries announced-child.mjs and what its contract
   buys, and the smoke:web:app paragraph records why the spawn/readiness step
   moved out of the smoke (same reason teardownWebServer left prod-web-server's
   stop()). README's test:scripts row names the new suite alongside
   resolve-node-bin's.

Not mirrored into .github/copilot-instructions.md: that file is a distillation
of the rules a reviewer cites against a diff, and deliberately excludes the
project-structure tree and tooling inventory.

09b35489aa test(scripts): cover the readiness-timeout teardown path (#2000 review)
Copilot's review is right that the fix was unproven: smoke:web:app's happy path
always receives the announcement, so `npm run ci` never exercised a child that
stays alive *through* the readiness timeout — exactly the case that orphaned a
live server holding its port. A regression there would be silent in CI and
would surface only as a stray process on a later run.

Extract the spawn/readiness ownership into scripts/lib/announced-child.mjs
(the same move prod-web-server.mjs made for teardownWebServer, and for the same
reason), and add scripts/lib/announced-child.test.mjs under `test:scripts`.
The tests drive real `node -e` children rather than spies, so the assertion is
that a real process is reachable and killable, not that a mock was called: the
timeout case asserts the child was published before the wait, is still alive
when the throw lands, and is actually stopped by kill. The early-exit and
spawn-failure paths are covered alongside it, plus the both-streams scan.

smoke-web-app.mjs keeps its behavior — startMcpServer() now delegates the
spawn and publishes the child via `onSpawn`.

031991cc90 chore: three small cleanups from the v2.2.0 merge review
1. clients/web/.npmignore's explanatory comment still said the root "files"
   allowlist restricts publishing to build/ and dist/ and that everything else
   under clients/web "stays out regardless". #1934 added clients/web/static to
   that allowlist, so the claim was false — in a file that exists precisely
   because a packaging contract was misread once. Name static/ and say why it
   ships (read from disk at runtime by sandbox-controller.ts, at a path
   relative to the runner dir).

2. Replace the four unjustified `as unknown as Response` doubles in
   useServers.test.tsx with real Responses over real ReadableStreams: a
   null-body Response for the `!res.body` guard, a stream whose pull throws for
   the reader-rejects case, and pull-driven streams for the multi-frame and
   priming-comment cases (pull runs once per read, so the counting and the
   blocking second read behave exactly as the hand-rolled reader doubles did).
   The doubles are now structurally type-checked against the Response API.

3. scripts/smoke-web-app.mjs orphaned the MCP test server on a readiness
   timeout: startMcpServer() returned the child only once the announcement
   line matched, so a child that was alive but never announced left `mcpServer`
   unassigned, shutdown() could not stop it, and process.exit(1) left it
   holding its port. Publish the child to `mcpServer` the moment it is spawned,
   so every throw path is covered by teardown.

Closes #2000

7c77c2b15f fix(apps): address review of app-rendered elicitations
Eight findings from the Copilot review, all accepted.

Ownership across connections was the substantive one, in three parts. A
mid-session transport close reaches teardown only through
`clearAndAnnouncePendingPeerRequests`, whose emptiness check looked at the
native queues alone — so a lone app elicitation survived a dropped connection
with its modal still open; the check now counts the active set too. The web
bridge factory resolves its client at call time, so an entry queued by a
replaced `InspectorClient` could rebuild against the *next* one and answer
through a different server; the host now drops every entry synchronously on
the swap (`AppElicitationController.failAll`) rather than racing core's
awaited teardown. And the request id was only monotonic within one client, so
each replacement client's first request was `app-elicitation-1` — settling
that id could resolve the wrong server's request. It now carries a
per-instance prefix.

Result validation now parses the whole value with `ElicitResultSchema` before
the requested-schema check, instead of inspecting `action` by hand: a
`{ action: "decline", content: { x: {} } }` used to pass, though the standard
result permits only primitives and string arrays in `content`.

The dialog's accessible name now includes the request id and the prompt — two
concurrent elicitations can be for the same app URI, and the previous name
made those indistinguishable, which is what the comment beside it claimed to
prevent.

`observeAppCapabilities` takes a minimal structural `onmessage` contract
(generic over the message type, since a handler typed for a narrower message
is not assignable to one typed for `unknown`), removing the double cast at the
call site.

`smoke:web:elicit` now fails on an uncaught page error after a successful
drive, and captures the async half of that class off the console channel, as
its two sibling smokes do — it could otherwise print OK over a broken bundle.

Adds the tests each fix needs, including the two the review asked for
directly: that `advertiseElicitation` reaches the `AppBridge` constructor, and
that it is absent by default.

08fc20a22d feat(apps): negotiated app-rendered form elicitations
Let a server hand a form `elicitation/create` to an MCP App and return the
app's ordinary `ElicitResult`, with the native elicitation form as the
fallback on every failure.

No second extension, no custom method, and no custom result shape: the only
new wire surface is a nested `elicitation` flag on the existing
`io.modelcontextprotocol/ui` extension on each side, plus
`_meta.ui.resourceUri` on the request. App rendering is selected only when
all four gates hold — client `elicitation.form`, client MCP Apps MIME type,
the nested `elicitation` setting on BOTH peers, and a valid absolute `ui://`
URI on the request.

Only the web client advertises the nested client-side setting, and only
because it has a sandbox renderer: supplying
`InspectorClientOptions.appElicitation` is what opts a client in, so CLI and
TUI keep advertising the MIME type without ever claiming they can resolve an
elicitation through an app.

Routing lives in the one funnel both entry points already use
(`enqueuePendingElicitation`), so the inbound handler and the MRTR driver
cannot diverge. Ownership is request-scoped — a per-request id keys the
renderer, iframe and bridge — so two concurrent elicitations can never
resolve through each other's bridges. An explicit `decline`/`cancel` is a
completed elicitation and goes back to the server; everything else (absent or
malformed metadata, resource/sandbox/bridge failure, an app with no
elicitation capability, a timeout, an invalid result or one that fails the
requested schema) falls back.

The Inspector speaks the ext-apps#733 / SEP-3118 wire protocol but cannot yet
consume its helpers — the released `@modelcontextprotocol/ext-apps` (1.7.5)
predates that PR. `core/mcp/appElicitation.ts` and
`AppRenderer/requestAppElicitation.ts` mirror it exactly and are marked for
deletion once a release containing it ships. One consequence needed its own
seam: ext-apps 1.7.5 parses the view's `ui/initialize` through a schema that
strips `elicitation`, so an app that correctly advertises it would look like
one that did not, silently turning every negotiated elicitation into a
fallback. `AppRenderer/appCapabilities.ts` records the raw frame instead, and
prefers the bridge's own value once it carries the key.

`AppRenderer` now takes an `AppRenderSource` union rather than a `Tool`, so
the same renderer and bridge factory serve an App tool and an elicitation
without either faking the other's shape.

Adds the public fixture (`app_choose_option` + a self-contained
`ui://demo/choose-option.html` app covering accept/decline/cancel), its two
showcase configs, and `smoke:web:elicit`, which drives the negotiated path
end to end in headless Chromium and then the same tool against a server that
never advertised the capability, asserting the native form takes it.

Closes #1854

c93552139c fix(scripts): keep the resolver local, complete the cmd.exe quoting
Copilot review round 3, all three real:

- `require.resolve.paths()` also appends Node's GLOBAL FOLDERS
  ($HOME/.node_modules, $HOME/.node_libraries, $PREFIX/lib/node) and any
  NODE_PATH entries, so round 2's lookup could satisfy a missing repo
  install from a GLOBALLY installed typescript/vite — measuring the
  programs with the wrong compiler instead of producing the actionable
  "run npm install" this helper promises. Filter to the node_modules
  directories on fromDir's own ancestor chain.
- The quoting predicate missed characters cmd.exe still parses, notably
  parentheses (`C:\Temp(1)`), and quoting cannot suppress `%VAR%` at all
  — expansion happens before quotes are processed. Extracted to
  lib/win-shell-args.mjs with a broad predicate and a hard error on `%`
  rather than a silently different path. `platform` is a parameter so the
  Windows behavior is exercised on the POSIX machines that run the suite.
- AGENTS.md claimed pack-and-verify spawns via `process.execPath`; it does
  not, and cannot — its children are `npm` and the installed `.bin` shim.
  State the exception and why.

b399bc64e1 fix(scripts): find the manifest without exports, quote shell args on Windows
Copilot review round 2 (suppressed comments), all three real:

- `require.resolve("<pkg>/package.json")` is governed by the package's
  `exports`, and Node keeps no special case for `./package.json` — so a
  package declaring an `exports` map without it threw
  ERR_PACKAGE_PATH_NOT_EXPORTED even though its bin was installed and
  spawnable, a false "not installed" pointing at `npm install` for a
  package already on disk. Walk `resolve.paths()` instead, which never
  consults `exports`. The docblock claiming the opposite is corrected.
- `shell: true` (needed at all on Windows to start the `.cmd` shims) makes
  Node hand `cmd.exe` one space-joined string, so an argument holding a
  path with a space splits in two. Every generated path in
  pack-and-verify lives under `tmpdir()`, which sits beneath the user
  profile. Quote them via `shellArgs()` at all four spawn sites, the
  command path included — the hazard predates this PR, so fix the class.
- Document the new module: `scripts/lib/resolve-node-bin.mjs` in AGENTS.md's
  scripts/ tree, its tests in the README's `test:scripts` row.

4b143ce043 fix(scripts): validate the bin name and that its file exists
Copilot review on #1997:

- A string-form `bin` is npm's shorthand for ONE command, named after the
  package, so ignoring `binName` let a typo silently resolve the package's
  only executable while bypassing the documented "declares no such bin"
  failure. Match it against the manifest's unscoped name instead.
- A declared bin whose file is absent (partial install) was returned
  unchecked. `process.execPath <missing>` still spawns and exits 1 with
  empty stdout, which `rawProjectListing` records as "no diagnostic
  captured" — reproducing the bogus every-file-uncovered report this
  helper exists to eliminate. Throw here, where the remedy is actionable.

Also restores `rawProjectListing`'s docblock, which the new `tscEntry`
block had orphaned above itself.

7164806be3 Merge origin/v2/main: move the #1939 npx fix into the shared tsc-program lib
Upstream #1965 moved the tsc --listFilesOnly machinery into
scripts/lib/tsc-program.mjs (shared with the new verify:dep-lockstep),
still spawning `npx` — which is ENOENT on Windows. Resolve the conflict
by taking upstream's factoring and porting the #1939 fix into the lib:
rawProjectListing and verify-typecheck-coverage's --showConfig pass now
spawn process.execPath with the cached, hard-failing tscEntry resolver
(exported from tsc-program.mjs). Fixture copies in both main tests pick
up the new lib import graph. verify:dep-lockstep now runs on Windows
too.

a9b9a917e3 chore(scripts): compare only the copies a program actually met
Two findings from the Copilot review of #1965, both real.

1. The candidates were flattened to package names before the version
   comparison, so a third install holding a different copy failed the guard
   even when no program loads that copy beside another — and the diagnostic
   named an install that never took part. `crossInstallPackages` now returns
   the co-occurrences themselves (name → program → install → entry paths) and
   `findSkew` compares per program, across only the installs that met there.

2. Folding a nested copy onto its outermost install lost the path that
   identifies which copy was loaded, and the version was then read from the
   install's top-level entry — absent or differently versioned, either way
   letting a real pair pass. `classifyModulePath` now also returns the
   `entryPath` npm keys the lockfile by, `topLevelLockVersions` becomes
   `lockVersionsByPath`, and each holder is priced from the entry the program
   resolved. A resolved copy with no lockfile entry is now a hard failure
   rather than a silently dropped holder.

The failure output prints `in <program>` with each holder's install path
beside its version, so a nested copy is distinguishable from a top-level one.

7f9be24bf3 chore(scripts): derive dep-lockstep candidates from what enters each tsc program
`verify:dep-lockstep` derived its candidate set from the packages the shared
first-party sources named *directly*, so a package whose declarations reach a
program only through another package's `.d.ts` was invisible to it — it could
skew across installs and recreate the two-copy blow-up #1896 was about while
the guard stayed green. `@modelcontextprotocol/sdk` was the live example: never
written in first-party code, yet 16 of its `.d.ts` files land in clients/web's
test program.

Replace the derivation with the measured one: list every client tsconfig
project with `tsc --listFilesOnly`, map each resolved `node_modules` file to
its owning install and package, and keep the packages that reach ONE program
from TWO installs. That is exactly the set that can put two structurally
distinct copies of a type in front of one checker. The rest of the guard is
unchanged — top-level lockfile comparison, deny-by-default, `TOLERATED_SKEW` as
a name allowlist scoped to within-a-major.

The listing machinery moves to `scripts/lib/tsc-program.mjs`, shared with
`verify:typecheck-coverage`, so the two guards can't disagree about what a
program contains. It is deliberately not cached to disk between the two
processes: a stale fingerprint would make a guard measure a program that no
longer exists and pass on a real miss. The second pass costs ~14s.

`TOLERATED_SKEW` is now empty. `jose` and `@modelcontextprotocol/ext-apps` are
root-only since #1970 and cannot skew; `react` (whose types are `@types/react`,
resolved from one install) and `hono` never reach one program from two
installs. Each would be a rationale for a skew that cannot occur.

Closes #1965

e3a026802b fix: resolve node bins via package.json instead of spawning npx .cmd shims so the verify/smoke scripts run on Windows
On Windows npx/npm are .cmd shims a shell-free execFileSync/spawnSync
cannot start (ENOENT since the CVE-2024-27980 hardening), so
verify:typecheck-coverage died at validate's second step — doubly
silently, echoing "(no diagnostic captured)" per project and then
reporting all 918 tracked files as getting no tsc pass — and
verify:build-gate, the smoke test-server bootstraps, and pack:verify's
npm pack failed the same way.

Add scripts/lib/resolve-node-bin.mjs: resolves the JS entry behind a
package's bin from <pkg>/package.json (deep resolution is blocked by
Vite 8's exports map) and spawns it via process.execPath — the same
walk npx --no-install did, cross-platform and shell-free. Switch the
six npx call sites to it; the npm pack call gets the existing
shell-on-win32 idiom instead (npm has no in-tree package to resolve).
An unresolvable tsc is now a hard "cannot measure" error with
actionable stderr, pinned by a new main() regression test.

678184ed3e fix(smoke): pin the teardown ordering, and correct a docblock the test refuted
Both round-3 review points, both mine.

1. The docblock claimed deleting `removeSafe` would leave "both the unit suite
   and all three smokes green" — written before the test existed and never
   updated, so it contradicted the test added in the same PR. Only the smokes
   would stay green; the unit tests are precisely what fails on it.

2. `assert.ok(hasExited(child))` after the await proved only that the child was
   dead by the time teardown returned. It passes just as happily if the catalog
   were removed *first*, or while an un-awaited `stopChild` was still pending —
   so it did not lock down the #1801 ordering it claimed to.

   Sample the directory from the child's own `exit` handler instead, registered
   before teardown so it runs ahead of stopChild's listener and observes the
   world at the instant the child dies. `removeSafe` cannot have run by then: it
   is sequenced after the promise stopChild resolves from that very event.

Mutation-checked against both defects the old assertion missed — removing before
stopping, and dropping the await. Each now fails the test; neither did before.

3d541388db test(smoke): exercise the real teardown path, not just removeSafe
Copilot was right that the previous test proved only that `removeSafe` can
delete a directory — it never drove `stop()`, so deleting the cleanup call
would have left the unit suite AND all three smokes green. That is exactly the
regression these tests exist to catch, and they did not catch it.

Extract the teardown into an exported `teardownWebServer({ child, catalogDir,
label })`, which `stop()` now delegates to, and drive it against a stand-in
child process (a real `node -e setInterval` that stays alive until signalled)
rather than a mock. Three cases:

  - it removes the catalog dir it was given (asserted on the dir itself, not a
    spy, so the assertion cannot drift from the behavior);
  - it awaits the child's exit before removing — the #1801 race in one
    assertion, since losing the await is otherwise invisible;
  - an already-dead child is not an error, which is the failure path a smoke
    takes when it calls fail() after the launcher has crashed.

Mutation-checked: with the `removeSafe` call deleted, 2 of the 3 now fail
(previously: 0). AGENTS.md updated to match.

Signed-off-by is now on every commit (#1978 DCO); the requirement itself is
undocumented and tracked in #1979.

4a993fc45a docs(smoke): document the throwaway-catalog invariant and fix the label JSDoc
Addresses the two review comments that still applied to HEAD (the third, the
stop() race, was already fixed in a8022138).

- AGENTS.md still described the prod-web-server helper as shared by only
  smoke:web and smoke:web:browser, and said nothing about catalog isolation.
  It is the source of truth for these smoke mechanics, so record the invariant
  there: the temp catalog per run and why, that only the catalog (not HOME) is
  redirected, that teardown needs both halves of child-cleanup.mjs and is
  therefore async for every caller, and where the contract is unit-tested.

- The `label` JSDoc claimed the option prefixes the temp dir. It does not —
  that prefix is fixed at `smoke-web-catalog-` (deliberately, so every run's
  dir is greppable); `label` only prefixes teardown warnings.

16c96d44c3 fix(smoke): await the server's exit before removing its catalog, and test it
Addresses both Copilot review comments on #1978.

1. `stop()` removed the catalog dir immediately after a bare `child.kill()`,
   which only *delivers* SIGTERM. That is precisely the #1801 race
   `child-cleanup.mjs:11-17` documents, and it says both halves are needed:
   `stopChild()` closes the race on the normal path, `removeSafe()` makes the
   residual case harmless. I had used only the second. `smoke-web-app.mjs`
   already used `stopChild` for its MCP test-server child, so the helper was
   inconsistent with its own sibling. `stop()` is now async — it awaits
   `stopChild` and then removes — and all three callers await it
   (`smoke-web.mjs`'s `fail()` became async to match, so every call site had to
   `await fail(...)` or execution would run past it instead of exiting).

2. The isolation contract had no test. The smokes exit the process right after
   teardown, so a regression reintroducing the shared catalog — or dropping
   cleanup — would leave them all green. Split the two pure pieces out
   (`createTempCatalog`, `buildWebServerEnv`) and cover them in a sibling
   `prod-web-server.test.mjs`: a unique dir per run, no pre-created catalog
   file, the dir is removable, and an inherited `MCP_CATALOG_PATH` (or
   `MCP_AUTO_OPEN_ENABLED`) cannot beat the explicit one — the spread-then-assign
   ordering that guard depends on. `startProdWebServer` itself stays untested by
   design; it spawns a real launcher, which is the smokes' job.

29e3ce95b8 chore(smoke): run the web smokes against a throwaway catalog
`startProdWebServer` spread `process.env` without setting `MCP_CATALOG_PATH`,
so `smoke:web`, `smoke:web:browser`, and `smoke:web:app` all ran against the
developer's real `~/.mcp-inspector/mcp.json` — unlike `smoke:cli` / `smoke:tui`,
which have always driven a temp `--catalog`.

That made the web smokes both destructive and non-deterministic.
`smoke:web:app`'s deep link persists a `deep-link` server row, so a second run
finds it already on disk, racing hydration: the deep-link effect misses it in
`servers`, POSTs `addServer` anyway, and the backend answers 409. The app
swallows that 409 by design (App.tsx:2842) so the smoke still passed, but it
reported a spurious non-fatal console error that was really just residue from
the previous run.

Give the helper its own temp catalog dir and clean it up in `stop()` via
`removeSafe`, so cleanup can never turn a passing smoke red. Isolation lives in
the shared helper rather than per script, since every web smoke needs it.

Only the catalog is redirected — other per-user state under `~/.mcp-inspector`
stays shared, since isolating it means redirecting HOME wholesale, which would
also move the npx and Playwright caches these smokes depend on.

Verified: `smoke:web:app` twice in a row is now clean both times (previously
the second run reported the 409), the real catalog's mtime is unchanged, and no
temp dirs leak. CI never saw this — a fresh HOME per run made every CI run look
like a first run.

Closes #1977

288adbcfd6 chore(deps): enrol installs by package.json, and fail on a missing lockfile
From Copilot's fifteenth pass of #1962. `installDirs` filtered on the presence
of a lockfile, so a missing one silently removed that install from the
comparison rather than failing. For the root — the install every shared source
resolves from — that meant the guard could report success from client locks
alone, which is the deny-by-default contract inverted.

Enrolment is now by `package.json` (an install we are meant to compare), with
the root always enrolled, and a missing lockfile is a named, loud failure. A
`clients/` directory with no `package.json` is not an install and is skipped,
so a stray scratch dir isn't asked for a lockfile it should never have.

Three regression cases: a missing client lockfile in a fixture that IS skewed
(so failing open would show as a pass), a missing ROOT lockfile, and a stray
`clients/` dir that must not be enrolled.

e1768e44ce chore(deps): check the declared lockfileVersion, not just the packages key
From Copilot's fourteenth pass of #1962. `hasReadableLockShape` and the
diagnostic it drives both promise "lockfileVersion 2+", but the check only
looked for a `packages` table with a root entry. A file declaring v1 while
carrying such a table was accepted, produced an empty version map, and could
make a real skew read as aligned once only one other holder remained — the
same fail-open the shape check was added to close, through the half of the
contract that wasn't enforced.

The declared version is now verified: a finite number, 2 or greater. Absent,
non-numeric, and declared-v1-with-packages cases are all in the table.

8a2035c4d1 test(scripts): cover verify-format-coverage's sibling-guard vouch
From Copilot's thirteenth pass of #1962. This PR added `verify:dep-lockstep`
to the vouch loop in `verify-format-coverage.mjs` without a test for it. The
existing tests exercise `rootReachesScript` in isolation and the opposite
direction (dep-lockstep vouching for format-coverage), so a typo in a sibling's
name here would have left `test:scripts` green while that guard silently
stopped being enforced — the same "a gate that stops gating" failure the
vouch cycle exists to prevent, one level up.

Three cases, reusing the fixture-repo approach: dropping either sibling from
`validate` exits 1 naming that sibling, and with both wired no sibling is
reported missing. The last asserts on the *reason* rather than the exit
status, since the fixture has no client manifests to harvest globs from and
so fails later for an unrelated reason.

87c1e05420 chore(deps): count triple-slash type references as candidates
From Copilot's twelfth pass of #1962. A `/// <reference types="x" />` pulls in
a package's declarations exactly like an import does, but TypeScript reports
it in `preProcessFile`'s `typeReferenceDirectives`, not `importedFiles` — and
only the latter was read. A shared source using one could therefore load the
root's copy of a package alongside a client's without it ever entering the
candidate set, so its skew would pass. Same silent-miss direction as the
earlier syntax gaps, through a channel the parser switch didn't cover because
I only read one of its two outputs.

`typeReferencePackageNames` maps a directive to both candidates, since the
name is the *type* name and not the package: `node` resolves to `@types/node`,
while a package shipping its own declarations resolves to itself. Returning
both over-approximates, the safe direction — whichever isn't installed drops
out downstream. Scoped names mangle `@scope/pkg` → `@types/scope__pkg`,
TypeScript's convention. `path` references name a file, not a package, and are
ignored.

The real candidate set is unchanged at 17: no shared source uses a triple-slash
reference today. As with the other syntax fixes, this closes the channel
against the one that arrives later.

af63a07817 chore(deps): reject an unreadable lockfile instead of failing open
From Copilot's eleventh pass of #1962, and the most consequential kind of bug
for a gate: it failed *open*.

`topLevelLockVersions` returns an empty map for anything without a v2+
`packages` table — a lockfileVersion 1 file, or a malformed one. `main()` fed
that straight into the comparison, so such an install contributed no holders
at all, and a genuine skew among the remaining installs was reported as
aligned. The guard would have said OK to exactly what it exists to catch.

`hasReadableLockShape` now gates every discovered lockfile before any
comparison, requiring a `packages` object carrying the `""` root entry npm
always writes — "has a packages key" is not enough. An unreadable one is named
and exits 1, telling you to regenerate it. A JSON parse failure likewise
reports the file rather than dying on a bare SyntaxError with no path in it.

The empty-map behavior of the pure helper is kept and its test now says why it
is safe: the shape check rejects those inputs before they can reach
`findSkew`.

Three regression cases: a v1 lockfile in a fixture that IS skewed (so failing
open would show as a pass), a `packages` table with no root entry, and the
unit table for the predicate. Fixtures now write the `""` root entry, matching
real npm output.

32c827f089 test(scripts): exercise the dep-lockstep guard's executable path
From Copilot's tenth pass of #1962. The suite covered only pure helpers, so a
regression in source enumeration, install discovery, lockfile loading, the
sibling-guard vouch, or the nonzero exit on real skew would have left it
green — and the negative cases had only ever been run by hand, once per review
round.

Five end-to-end cases build a throwaway repo and run the guard as a
subprocess: aligned installs exit 0; a skewed one exits 1 naming the package
and every holder while leaving the agreeing package unreported; a package
imported only by `test-servers/src` still fails (so dropping the second shared
tree can't pass); a shared source matching no tracked file fails; and a
`validate` chain that stopped running `verify:format-coverage` fails the vouch
even when the versions are fine.

The fixture must be realpath'd. On macOS `tmpdir()` is `/var/…`, a symlink to
`/private/var/…`, and the guard runs `main()` only when `import.meta.url` (the
resolved path) matches `process.argv[1]` — so launching it via the unresolved
path loads the module and does nothing, exiting 0 silently. That is how all
five first "passed" as no-ops, and the comment records it.

48d74ba423 chore(deps): check each shared source contributed, not the aggregate count

`files.length === 0`, which stopped meaning anything once
`SHARED_SOURCE_FILES` was added: `vitest.shared.mts` alone keeps the total
nonzero, so a moved or renamed `core/` would leave the guard deriving
candidates from a near-empty set and passing on skew it exists to catch.

`sourcesWithNoFiles` now requires every configured dir and every named file to
have contributed, and names the ones that didn't. Directory matching is on a
path separator, so a prefix sibling (`core-internal/`) can't vouch for a
renamed `core/`.

Also drops two test comments left stale by the move to `ts.preProcessFile` —
they still described the deleted TRIVIA regex.

The guard resolves typescript from `clients/web`. The realistic way for that
to fail is a root install run with INSPECTOR_SKIP_CLIENT_INSTALL=1, which
leaves `clients/web/node_modules` empty — and a bare MODULE_NOT_FOUND stack
gives no hint that the fix is `npm install` at the root. Throw with that
guidance and the original error as `cause`.

Deliberately not a silent skip: an unrun guard guards nothing, which is the
failure mode the sibling-vouch ring exists to prevent.

fcd45037c9 chore(deps): extract specifiers with ts.preProcessFile; document the transitive boundary
From Copilot's sixth pass of #1962.

Take the TypeScript-parser suggestion, which was raised across three rounds
and was right. The regex scan got both directions wrong and every widening
traded one failure for the other: it *missed* valid syntax (`import x =
require(…)`, an import-attributes argument, a comment between tokens — each a
silent miss, so the package never entered the candidate set and its skew
passed), and it *invented* names from prose, since `// adapted from "react"`
is indistinguishable from an import to a pattern that cannot tell code from a
comment. The earlier prose test only passed because `cwd omitted` isn't a
valid package name.

`ts.preProcessFile` is the cheap answer I'd missed while arguing against the
full AST: TypeScript's lightweight pre-parse scanner, no parse tree and no
type checking, purpose-built to return module specifiers. It handles every
import form, trivia, strings, and regex literals, and never reads a comment as
code. typescript resolves from `clients/web`, which already carries it, via
the `createRequire` base `smoke-web-browser.mjs` established — a bare import
would resolve relative to `scripts/`, not the cwd.

The derived set drops 18 → 17 real names: every genuine package is retained
and the one prose artifact is gone. Regression tests now use *real* package
names in comments and strings, the case the old test couldn't cover.

Also records the KNOWN BOUNDARY the review's other finding identified.
Candidates cover what the shared sources name directly, so a package reaching
the program only through another package's `.d.ts` is invisible —
`@modelcontextprotocol/sdk` is the live example, skewed 1.29.0 vs 1.30.0 and
present in web's program from both installs, never written in first-party
code. Closing it properly changes what the guard measures, so it is tracked
as #1965, with both candidate derivations measured there: a lockfile closure
is unusable (155 packages, 25 skewed, nearly all irrelevant tooling, and it
misses the SDK anyway), while `tsc --listFilesOnly` is correct and small
(15 for clients/web).

2f1d97e7bb chore(deps): treat line comments as trivia too in the import scan
From Copilot's fifth pass of #1962. `TRIVIA` covered block comments but not
`//`, despite the contract right above it saying a comment is legal wherever
whitespace is — so `import(// lazy\n"pkg")`, `require(// lazy\n"pkg")`, and
`from // reason\n"pkg"` were stepped over, and such a package would never
enter the candidate set. Same silent-miss direction as the block-comment gap.

Both comment syntaxes are now covered. The line-comment branch runs to
end-of-line only; the newline itself is matched by TRIVIA's `\s` branch.
Regression test added alongside the block-comment one.

The derived set is unchanged at 18 real names — widening trivia does not
admit prose, since a specifier must still follow immediately and
`packageNameOf` rejects anything not shaped like one.

2dcf1450b2 chore(deps): see imports through comment trivia; name vitest.shared.mts in the README
Both suppressed comments from Copilot's fourth pass of #1962.

TypeScript allows a comment anywhere whitespace is legal, so
`import(/* webpackIgnore: true */ "pkg")` and `from /* why */ "pkg"` are
valid imports the patterns stepped over. That is the dangerous direction: a
missed specifier never enters the candidate set, so the package's skew passes
the guard silently, against the over-approximation the module claims. A
`TRIVIA` fragment now stands in for `\s*` at every inter-token position, with
regression cases for the commented static, dynamic, side-effect, and
`require` forms.

I did not move to the TypeScript parser. This is a root `scripts/` `.mjs`
tool with no bundler and no TS dependency; pulling in a compiler API to read
import specifiers is a lot of machinery for a scan that only needs to
over-approximate, and each missed form is a one-line pattern with a test
beside it. The derived set is unchanged at 18 real names, so nothing here
widens what is checked today.

The README's command row also still described the candidate scan as `core/`
and `test-servers/src` only, omitting the `vitest.shared.mts` the guard now
includes; it also never mentioned that an allowlisted package is tolerated
only within a major. Both stated.

35317fd9ed chore(deps): scope the allowlist to a major, cover vitest.shared.mts, fix the vouch comment
All four suppressed comments from Copilot's third pass of #1962. Each was
correct.

The candidate boundary omitted `vitest.shared.mts` — root-owned, imported by
every client's vitest config, and already treated as shared non-client source
by `verify:typecheck-coverage`. It imports only Node built-ins today, which
is exactly why the omission would have gone unnoticed until a third-party
import appeared there, resolved from the root, and skewed. Shared *files* are
now a first-class list beside the shared dirs.

The allowlist was a blanket exemption by name. Each entry's rationale
establishes that a patch/minor difference is benign, which is no evidence
that a React 18-vs-19 or Hono 4-vs-5 split would be — that is a different
type surface. Being listed now tolerates skew only *within a major version*;
a cross-major skew fails like anything else. Deriving the major from the
lockfile version keeps this automatic, with no per-package range to maintain
and bump. A version that can't be parsed is treated as "cannot prove same
major" and fails rather than passes.

`verify-format-coverage.mjs`'s comment overstated the vouching graph: the
three guards do not each check the others. This one checks both siblings;
each sibling checks only this one. Described as it actually works.

The AGENTS.md rule said to bump a shared dependency in "root + all four
clients", but launcher declares no zod and `findSkew` ignores installs where
a package is absent — so the rule as written asked for spurious dependencies.
Reworded to every install that *declares* it, and mirrored in
`.github/copilot-instructions.md`.

The failure output follows: it no longer advises adding a package that is
already allowlisted, saying "MAJOR skew" instead, and it names all three
shared sources rather than the two dirs.

47e0ee059a chore(deps): match CommonJS and template-literal imports in the shared-source scan
From the suppressed comment on Copilot's second pass of #1962. Under-
approximating is the dangerous direction here: a package the scan misses
never enters the candidate set, so its skew passes the guard silently.

Three forms went unmatched. `import x = require("pkg")` and a bare
`require("pkg")` are the ordinary import syntax in `.cts` — which the
previous commit just admitted to the scan, so leaving them out would have
been an inconsistency introduced by that widening. A dynamic import carrying
import attributes (`import("pkg", { with: … })`) was missed because the
pattern required the closing paren. A static template literal
(`import(\`pkg\`)`) was missed for want of a backtick in the quote class.

Backticks are accepted only in the *call* forms. A `from` clause requires a
string literal, so allowing them there would buy nothing while reopening the
prose hazard the anchored specifier pattern closes: inline code in comments
is written with backticks throughout this codebase, and admitting it inflated
the derived set from 18 names to 41 with prose fragments (`tools`,
`connect()`, `messages`). Inert today, since a name absent from every
lockfile contributes nothing — but a prose word colliding with a real package
name would silently widen the set. Pinned with a regression test.

The real set is unchanged at 18, so these forms add no package today; they
close the syntax against the one that arrives later.

e480fdc49d chore(deps): cover .mts/.cts in the shared-source scan, fix the README validate row
Both from Copilot's review of #1962.

The candidate-set enumeration matched only `.ts`/`.tsx`, while
`verify:format-coverage` and `verify:typecheck-coverage` both gate all four
TypeScript extensions. No `.mts`/`.cts` exists under `core/` or
`test-servers/src` today, which is exactly why the omission would have gone
unnoticed until a shared dependency arrived through one and skewed — the
failure this guard exists to prevent. Extract the rule as the exported
`isSharedSourceFile` predicate, cover all four extensions, and pin it with
regression tests (including path-boundary anchoring, so a `core-internal/`
sibling isn't swept in).

The README's `validate` row also omitted `test:scripts` and claimed typecheck
was cli/tui only; launcher runs one too, and web typechecks via `tsc -b`
inside its `build`. Restate the row to match the actual script chain.

6c33da38c9 chore(deps): align zod across installs and guard against version skew
Closes #1896

`clients/web`'s `tsc -b` exhausted the 4GB default heap at zod 4.4.x. The
cause is not a zod regression nor a pathological inference site of ours: it
is two copies of zod at *mismatched versions* inside one tsc program.

`clients/web/tsconfig.test.json` compiles `test-servers/src`, whose files
resolve zod (and the SDK's zod) from the **root** install, alongside web's
own sources, which resolve from `clients/web/node_modules`. At 4.3.6 vs
4.4.3 TypeScript must relate two structurally-distinct declarations of every
`@modelcontextprotocol/*` schema type, which is exponential over a recursive
generic surface — `TS2589 Type instantiation is excessively deep`, then OOM.

Bumping root zod to 4.4.3 and changing nothing else returns the build to
baseline: 11.4s and 2,567,882 instantiations, against 11.2s / 2,567,503 at
4.3.6. Two copies at the same version are harmless; skew is what explodes.

So drop the `~4.3.6` hold on `clients/web` and move all four manifests and
lockfiles to zod 4.4.3 together, and add `verify:dep-lockstep` to `validate`
to keep them there. The guard derives its candidate set from what `core/`
and `test-servers/src` import, compares the committed lockfiles' top-level
entries, and fails deny-by-default on any skew not in the annotated
`TOLERATED_SKEW` allowlist. It joins the existing mutual-vouch ring so
dropping it from `validate` is caught by `verify:format-coverage`.

5401e527e6 fix: handle spawn failure of the MCP test server in smoke:web:app
Copilot's third pass (suppressed comment) caught the remaining hole in the
child-process handling: `spawn()` reports a failure to start via an `error`
event, not `exit`. With no `error` listener Node throws it uncaught, replacing
the smoke's diagnostic with a raw stack — and because `exit` never fires in that
case, the readiness poll would otherwise spin for the full 30s before reporting
a timeout that misattributes the cause. `close` is now listened to alongside
`exit` for the same reason: it fires in cases `exit` does not.

prod-web-server.mjs already documents this exact hazard for the launcher child;
this brings the test-server child in line.

Both new branches verified by hand:
  - unspawnable executable → "could not spawn the MCP test server (…): spawn
    /nonexistent/node-binary ENOENT", immediately, instead of an uncaught throw
  - missing module → "MCP test server exited early" with the loader stack, fast,
    with no 30s hang

Full `npm run ci` green.

556aaca298 fix: fail smoke:web:app on async crashes, not just sync page errors
Copilot's second pass (suppressed comments) caught a real gap: the smoke
listened only for `pageerror`, which is the *synchronous* half of the
uncaught-crash class. Its async twin — an unhandled rejection, or a failed
dynamic import (this app lazy-loads chunks) — is not a `pageerror`; Chromium
reports it on the console channel. So an async crash during the app-open path
could leave the smoke green.

smoke-web-browser.mjs already solved this; this now mirrors it exactly — same
FATAL_CONSOLE pattern, same split between hard failures and diagnostics, so
benign noise (a font-CDN miss, a React warning) still can't flake CI. Fatal
console errors are now included both in the catch-block diagnostics and in the
final assertion, which is where they were missing.

Confirmed working on a passing run: a benign 409 subresource error is reported
as a non-fatal diagnostic rather than failing the smoke.

Full `npm run ci` green.

3f4f68699e fix: give smoke:web:app its own port; note the App config's era in the table
Copilot review on #1934, both comments actionable:

- smoke:web:app defaulted to 6299 — the same port smoke:web uses — while its
  own comment claimed the port was "distinct … so back-to-back runs can't
  collide". The three web smokes run sequentially in `npm run smoke`, so it
  passed, but a slow teardown, a TIME_WAIT socket, or a parallel run would
  EADDRINUSE it. Moved to 6297 (smoke:web 6299, smoke:web:browser 6298) and
  rewrote the comment to name the actual values rather than assert distinctness.

- The showcase table tells readers to connect with Protocol Era = Modern unless
  noted, and mcp-app-http.json is legacy-only. That was stated in the prose
  below but not in the row, so a reader scanning the table would try Modern
  first. Marked the row.

Verified: smoke:web:app passes standalone on 6297, and the full `npm run smoke`
chain passes with all three web smokes on distinct ports.

cf0ed4ac78 test: add smoke:web:app — drive a real MCP App end to end in headless Chromium
`smoke:web:browser` stops at first paint and never connects to a server, so
everything downstream of the connect — the Apps tab, the sandbox controller,
the UI-protocol bridge — was unexercised by any smoke. That is the code #1859
broke, and nothing would have caught a regression in it.

smoke:web:app boots the same prod --web server, spawns the mcp-app-http.json
composable server, and drives connect → open app → widget ready through one
deep-link navigate. The assertion is the documented data-app-status="ready"
contract, which the renderer only reports once the widget has loaded inside the
sandbox iframe AND completed its bridge handshake — so a single attribute
covers the proxy being served, the UI resource loading, and the handshake.

Two mechanics found by running it, both silent-failure shaped:
  - server-composable.ts announces readiness on stderr, not stdout, so watching
    stdout alone times out with an empty diagnostic. Both streams are scanned.
  - the bound port is not the configured one — createTestServerHttp resolves via
    findAvailablePort(), which walks upward when the port is taken. The smoke
    parses the announced URL instead of assuming 3130.

Scope: this runs against the repo build tree like every other smoke, so it would
NOT have caught #1859 itself (a packaging failure; the file is always present
in-repo). pack:verify owns that dimension — the two are complements, and the
header comment says so. A cheap structural pre-check does assert the proxy page
sits where sandbox-controller.ts resolves it, so a move/rename fails fast.

Both failure modes verified by hand: with clients/web/static removed, the
pre-check fires; with the pre-check bypassed, the data-app-status assertion
catches it independently.

22da48c652 fix: ship clients/web/static so the MCP Apps sandbox proxy loads
`clients/web/static/sandbox_proxy.html` is a committed source file, not a
build artifact, and it was never listed in the root package.json "files"
allowlist. `sandbox-controller.ts` reads it at runtime as
`<runner dir>/../static/sandbox_proxy.html`, so it resolved fine in-repo but
was absent from every published tarball — the read threw and the controller
served its "Sandbox not loaded" fallback page, breaking the Apps tab for
anyone running `npx @modelcontextprotocol/inspector`.

v1 shipped the equivalent as `server/static` in both the root and the server
workspace "files" lists; that entry has no counterpart in v2.

Add `clients/web/static` to the allowlist, and assert it in pack:verify twice
over — once in the tarball packlist and once on disk after install, since what
the runtime needs is the path *relative to* clients/web/build rather than mere
presence in the tarball.

No .npmignore change is needed: clients/web/.gitignore does not list `static`,
so the nested-gitignore packlist hazard that hid `build/` does not apply here.

fix(scripts): await the pack:verify web child's exit before removing its work dir (#1895)
* fix(scripts): await the pack:verify web child's exit before removing its work dir

`pack-and-verify.mjs` had the same kill-then-remove shape that made
`smoke:tui` flake with ENOTEMPTY in #1801: `verifyWeb()`'s
`finally { stop() }` only *delivered* SIGTERM, then the main flow
`rmSync`'d the work dir immediately, and `fail()` did the same back to
back.

Applies the #1814 treatment, factored into a shared
`scripts/lib/child-cleanup.mjs` so the two scripts can't drift:

- `stopChild()` — SIGTERM, await the child's `exit`/`close`, escalate to
  SIGKILL after a grace period, and ultimately proceed with a warning so
  a wedged child can never hang the script. `verifyWeb()`'s `stop()` now
  goes through it and is awaited, so the child is gone before the caller
  removes `work`.
- `removeSafe()` — `rmSync` that warns instead of throwing. Used on both
  success-path removals (a leftover temp dir must never fail a run that
  passed) and in `fail()`, where an ENOTEMPTY could otherwise bury the
  real diagnostic under an rmSync stack and skip the "tarball retained
  at ..." hint. `fail()` stays synchronous — it is called from sync
  contexts and ends in `process.exit()` — so it best-effort signals the
  child; `removeSafe()` is what makes that safe.

`smoke-tui.mjs` adopts `removeSafe()` for its `cleanup()`. Its `done()`
keeps its bespoke wait (documented inline): that one must keep waiting
for `close` *after* `exit` on a shorter re-armed deadline so the quoted
output is complete, which `stopChild()`'s first-of-exit/close contract
deliberately does not do.

Adds `scripts/lib/child-cleanup.test.mjs` (10 cases, `node --test` via
`npm run test:scripts`) covering the SIGTERM/SIGKILL escalation, the
`close`-only spawn-failure path, the never-hang give-up, late events
after giving up, and that `removeSafe` warns rather than throws.

`npm run ci` passes, and `npm run pack:verify` (not in the gate — needs
network) was run end to end and passes with no cleanup warnings.

* fix(scripts): normalize stopChild's graceMs and correct removeSafe's JSDoc

Copilot review round 1 on #1895.

- `stopChild()` trusted `graceMs` as given, but call sites build it as
  `Number(process.env.X ?? 5000)` — a typo yields `NaN`, which
  `setTimeout` treats as `0`. That would fire SIGTERM and SIGKILL in the
  same tick and print "did not exit within NaNms", collapsing the whole
  escalation silently. New exported `normalizeGraceMs()` falls back to
  `DEFAULT_EXIT_GRACE_MS` for anything non-finite or non-positive, with
  two tests: the table of bad values, and an end-to-end one asserting a
  `NaN` grace period still leaves only SIGTERM sent a turn later.
- `removeSafe()`'s `@returns` said "true if the path was removed", which
  is inaccurate for a missing path (`force: true` makes it a no-op
  success). Reworded to say what it actually reports.

`npm run ci` passes.

fix: wait for the TUI to exit before removing its temp dir (#1801) (#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.

* 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.

* 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`.

* 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.

test(cli,tui): typecheck the __tests__ dirs (#1791) (#1799)
* 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.

- App.test.tsx: type the OAuth spies against the real InspectorClient method
  signatures (`vi.fn<InspectorClient["…"]>()`) and forward `Parameters<…>`
  tuples from the FakeClient wrappers, so `toHaveBeenCalledWith(...)` on the
  six OAuth-lifecycle spies stays argument-checked under the new gate rather
  than accepting anything via `unknown[]`. `getOAuthState` regains its wide
  `OAuthConnectionState | undefined` return.
- Typecheck the client config files too: add `vitest.config.ts` / `tsup.config.ts`
  (and tui `dev.ts`) to each src `tsconfig.json` include — they were the one
  first-party surface still getting no tsc pass.
- Trim the redundant `src/**/*` from each `tsconfig.test.json` include (tsc
  pulls in the src the tests import; the src-only config already checks it).
- Rename the tui settings helper to `oauth-test-fakes.ts` to match cli's, and
  soften both factories' docstrings to stop naming a loader they don't mirror
  field-for-field.
- Fix a stale `@modelcontextprotocol/inspector-core/...` specifier in a
  createRemoteTransport JSDoc example (the same wrong package name the gate
  caught in the cli tests, surviving in a comment).

  signature (returns a `URL`), so it no longer diverges from production; the
  one mockResolvedValue is updated to a URL.
- makeFakeCliOAuthClient members are typed against the real CliOAuthClient
  signatures (not bare vi.fn()), so a wrong-signature override is rejected.
- HistoryTab: revert the `entry()` `message: unknown` widening (it un-checked
  the ~15 well-formed fixtures) and instead scope a named `MALFORMED` cast to
  the two intentionally-malformed messages.
- Typecheck the launcher `__tests__` too (the same gate hole in the one client
  the PR hadn't touched): new clients/launcher/tsconfig.test.json + a typecheck
  script folded into validate. Completes the "every client's __tests__ is
  typechecked" invariant.
- Doc the new test-typecheck + config-file typecheck in AGENTS.md.

* test: address round-3 nits — launcher config typecheck, callTool typed, docs

Responds to the round-3 @claude review of #1799 (all non-blocking):

- launcher: add `vitest.config.ts` to tsconfig.test.json's include (it was in
  neither project — the build config's rootDir: ./src rejects it). 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.

* test: address round-4 — durable typecheck-coverage guard + launcher/doc nits

Responds to the round-4 @claude review of #1799 (all non-blocking):

- Add `verify:typecheck-coverage` (scripts/verify-typecheck-coverage.mjs), the
  typecheck-coverage analog of verify:format-coverage and the durable guard for
  the invariant this PR establishes: for each Node client it runs the tsconfig
  projects its `typecheck` names with `tsc --listFiles`, unions them, and fails
  on any tracked .ts/.tsx that lands in no 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.

* test: address round-5 — wire-check the guard, --listFilesOnly, into validate

Responds to the round-5 @claude review of #1799:

- Finding 1 (the pre-merge one): the guard now ports verify:format-coverage's
  reachability checks — it asserts each client's `typecheck` is reachable from
  its own `validate` and that the root chain runs each client's `validate`, so
  it can't stay green while measuring a typecheck nothing invokes. 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). Docs (README/AGENTS) updated for the validate placement.

* chore(scripts): address round-6 guard nits — dedupe wiring, robust diagnostics

Responds to the round-6 @claude review of #1799 (all guard-ergonomics nits):

- Nit 2: extract the shared reachability logic (`reachableScripts`,
  `rootRunsClientValidate`) into scripts/lib/npm-scripts.mjs and consume it from
  BOTH verify-format-coverage.mjs and verify-typecheck-coverage.mjs, so the
  "is this gate actually run?" wiring can't drift between them (same rationale
  as scripts/lib/prod-web-server.mjs).
- Nit 1: typecheckProjects now harvests `-p`/`--project` from every script
  reachable from `typecheck` (not the single string), so a delegating
  `typecheck` (`npm run typecheck:src && …`) is handled instead of failing with
  a false "names no -p project" diagnosis. 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).

* chore(scripts): round-7 — guard .mts/.cts too; drop dead export

Responds to the round-7 @claude review of #1799:

- Finding 1: verify-typecheck-coverage now requires a tsc pass for tracked
  `.mts`/`.cts` (not just `.ts`/`.tsx`), matching verify-format-coverage's
  extension set — `.mts` is already the shared-config idiom here, so a client
  `vitest.config.ts` → `.mts` rename can no longer drop out of both the tsconfig
  include and the guard's required set. 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).

* test: round-8 — single casts in HistoryTab, uniform wrappers, doc scope

Responds to the round-8 @claude review of #1799:

- Finding 1: reduce the `MALFORMED` helper and `entry()`'s return cast from
  `as unknown as` to a single `as` (both compile clean — the malformed shapes
  are comparable to the JSONRPCMessage union), and delete the false "only
  option" sentence. 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).

Nits 4 (js config files out of the typecheck guard by construction) and the
footnoted callTool/ancestor-tsc items left as agreed.

* test: round-9 — drop entry()'s harmful cast; guards vouch for each other

Responds to the round-9 @claude review of #1799:

- Finding 1: remove `entry()`'s `as MessageEntry` return cast in
  HistoryTab.test.tsx. It was unnecessary (the spread of Partial<MessageEntry>
  over complete defaults is directly assignable) and harmful — it silenced type
  errors in the helper's OWN default fields (a `direction`/`method` typo now
  surfaces TS2820/TS2353). 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.

* test: round-10 — reject non-checking typecheck passes; pre/post hooks; docs

Responds to the round-10 @claude review of #1799:

- Finding 1: verify-typecheck-coverage now rejects a `-p <project>` whose own
  command carries `--noCheck` or `--listFilesOnly` — such a pass lists files
  without type-checking them, which previously satisfied both the wiring and
  file-coverage halves while checking nothing. (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).

* fix: round-11 — launcher build excludes tests; guard catches all noCheck vectors

Responds to the round-11 @claude review of #1799:

- Finding 1 (shipping bug): clients/launcher/tsconfig.json now excludes
  `**/*.test.{ts,tsx}` (matching cli/tui). launcher's `build` is an EMITTING
  tsc over src/**, and clients/launcher/build is in the root `files` allowlist,
  so a co-located `src/**/*.test.ts` would have been compiled into the published
  tarball. 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.

* fix: round-12 — exclude .mts/.cts tests from build; drop false integrity line

Responds to the round-12 @claude review of #1799:

- Finding 1 (tarball, again): the round-11 test exclude only covered
  `.ts`/`.tsx`, so a co-located `src/*.test.mts` still compiled into launcher's
  shipped `build/`. 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.

* chore(scripts): round-13 — implicit-tsconfig + derived clients; diagnostics

Responds to the round-13 @claude review of #1799:

- Finding 1: verify-typecheck-coverage now understands a `tsc` command with no
  `-p`/`-b` project flag — it resolves the implicit `./tsconfig.json` (tsc's own
  default), so the idiomatic `tsc --noEmit` form counts as coverage instead of
  producing false "in no tsconfig project" failures. 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.)

* chore(scripts): round-14 — enumerate clients from disk (fail-closed)

Responds to the round-14 @claude review of #1799:

- Finding 1: replace the root-chain `CLIENTS` derivation (round 13) with a
  disk enumeration — every `clients/<name>` whose package.json has a `typecheck`
  script. 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).

* chore(scripts): round-15 — enroll-or-exempt enumeration; normalize `cd ./`

Responds to the round-15 @claude review of #1799:

- Finding 1: the disk enumeration keyed on the presence of a script named
  `typecheck`, so renaming it silently dropped the client (112→53, still green)
  — contradicting the docstring. 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.

* chore(scripts): round-16 — anchor wiring match; close enumeration axes

Responds to the round-16 @claude review of #1799:

- Finding 1 (only false-PASS): rootRunsClientValidate matched the client dir as
  a bare substring, so a prefix-sibling (`clients/tui` vs `clients/tui-next`)
  satisfied the wiring check for the shorter name — dropping a client from the
  root chain went green if a sibling was present. 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.)

* chore(scripts): round-17 — share quote-aware tokenizer between guards

Responds to the round-17 @claude review of #1799:

- Finding 1: the two coverage guards parsed shell strings differently —
  verify-format-coverage had a quote-aware tokenize(); verify-typecheck-coverage
  used a raw regex. 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.

* chore(scripts): round-18 — match tsc by basename; strip quotes on both halves

Responds to the round-18 @claude review of #1799:

- Finding 1 (regression from round 17): `tokens.includes("tsc")` didn't match a
  path-invoked binary (`node_modules/.bin/tsc`), which the previous `\btsc\b`
  regex did — so such a `typecheck` was falsely reported as naming no project.
  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).

* test: round-19 — typecheck test-servers' unimported bin; --prefix wiring form

Responds to the round-19 @claude review of #1799:

- Finding 1: `test-servers/src/server-composable.ts` (a `#!/usr/bin/env node`
  bin entry nothing imports) got no tsc pass — the barrel alias covers the other
  13 test-servers/src files transitively, but not this one, and its own build
  runs `tsc --noCheck`, so its errors were emitted into `test-servers/build`
  unchecked. 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.

* chore(scripts): round-20 — anchor validate tail; guard shared-source class

Responds to the round-20 @claude review of #1799:

- Finding 1 (false PASS): the wiring matcher's tail `/\brun validate\b/` also
  matched `run validate:fast` (`:` is a word boundary) — a DIFFERENT script that
  may skip typecheck. 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.

* chore(scripts): round-21 — deny-by-default non-client coverage

Responds to the round-21 @claude review of #1799 (findings 1 & 2, one fix):

- Replaced the `SHARED_ROOTS` allowlist with a deny-by-default non-client set:
  all tracked TS minus `clients/*` (per-client pass) minus a reasoned `core/`
  exemption (covered by web's `tsc -b`). 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

* chore(scripts): round-22 — narrow core/ exemption to what web's tsc -b covers

Responds to the round-22 @claude review of #1799:

- Finding 1: the `core/` exemption was whole-tree, but web's `tsc -b` only
  covers `core/**/*.ts` MINUS co-located `*.test.ts(x)` (its app project's
  include). 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)".

* chore(scripts): round-23 — core exemption mirrors both web projects

Responds to the round-23 @claude review of #1799:

- Finding 1: round 22's `isExemptCoreFile` mirrored only web's app project, but
  web's `tsc -b` also builds `tsconfig.test.json`, which includes
  `core/**/__tests__/**/*.{ts,tsx}`. 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).

* chore(scripts): round-24 — enroll clients/web via tsconfig references

Responds to the round-24 @claude review of #1799:

- Finding 1: `clients/web` was whole-tree EXEMPT, but web's `tsc -b` only reaches
  what its four referenced projects include — a file at web's package root
  (e.g. `playwright.config.ts`) got no tsc pass and passed EVERY gate, fully
  silently. 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}`).

* 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.

* chore(scripts): round-26 — expand solution configs wherever harvested

Responds to the round-26 @claude review of #1799:

- Finding 1: the reference (`tsc -b`) path was selected only by "no typecheck
  script", so adding `typecheck: "tsc -b"` to web (the natural uniformity move)
  flipped it to the typecheck-script path, where the harvested solution config
  lists nothing → 665 false failures. 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.

* chore(scripts): round-27 — non-inertness follows references on both paths

Responds to the round-27 @claude review of #1799:

- Finding 1: round 26 made COVERAGE follow a solution config's references, but
  the non-inertness (`noCheck`) check on the typecheck-script path still only
  inspected the harvested solution (empty compilerOptions) — so a `noCheck` in
  a REFERENCED project was invisible there (caught only on the reference path).
  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.

* chore(scripts): round-28 — dedup shared leaf in checkingLeaves

Responds to the round-28 @claude review of #1799 (which found no new gate hole):

- Finding 1: `checkingLeaves` dedup'd the `checking` array but ran
  projectDisablesChecking + integrity.push on every visit, so a leaf reachable
  from two harvested projects produced a duplicate `noCheck` line (and a
  redundant `tsc --showConfig`). 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.

* test(scripts): unit-test the typecheck-coverage guard's parsers

Responds to the round-29 @claude review of #1799 (no new gate hole; the finding
is that the guard itself has no tests):

- Made the guard's pure helpers importable: exported `typecheckProjects`,
  `tscBuildStatus`, `tsconfigReferences`, `clientTsconfigReferences`,
  `resolveLeafProjects`, `isTsc`, `isDisablingFlag`, `isRequiredSource`, and
  moved the module-init + phase execution behind an exported `main()` run only
  when the file is executed directly (importing it for tests no longer runs the
  guard). 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.

* test(scripts): make test:scripts self-guarding; fill parser test gaps

Responds to the round-30 @claude review of #1799 (mutation testing killed 5/5;
findings are about the new test gate + suite completeness):

- Finding 1: `test:scripts` lacked the two properties the guard enforces for
  every tsc pass. verify-typecheck-coverage now asserts, in phase 1, that
  `test:scripts` is reachable from the root `validate` (via the already-imported
  rootReachesScript) AND that its tracked `scripts/**/*.{test,spec}.*` file set
  is non-empty and every file is matched by the command's glob (a new exported
  `globToRegExp`). 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.

* chore(scripts): round-31 — glob harvest follows delegation; brace/? globs

Round-31 review findings, both false failures in the new `test:scripts`
self-guard:

1. 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.

* 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.

* 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 ·

* 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 ·

* 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 ·

* 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). Mutation sweep 14/14.
`test:scripts` 25/25 · `verify:format-coverage` OK 919 · `npm run ci` green.

* chore(scripts): round-37 — register-not-mention; guard the discovery read

Both findings were introduced by round 36's content predicate.

1. 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.

* chore(scripts): round-37 nit 3 — one definition of the JS-extension check

Finding 2's fix hoisted the extension gate into `main()` (it must run before
the read), leaving a second copy of the regex inside the predicate that reads
as protection but can never fire there. Extracted as `isJsFile` and used in
both positions, so the two can't drift.

feat(web): enforce localhost-only binding; expand loopback origin allow-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.

chore: close a batch of quality-gate & tidy gaps (#1785 #1787 #1789 #1790 #1767) (#1792)
* chore: close a batch of quality-gate & tidy gaps (#1785 #1787 #1789 #1790 #1767)

Bundles five small, related tidy/gate items into one PR:

- #1785: delete the dead src/types/navigation.ts InspectorTab (0 importers;
  duplicated/drifted from utils/inspectorTabs InspectorTabId). src/types/
  now holds only ambient .d.ts stubs.
- #1787: add src/hooks/** to the web coverage `include` (it was silently
  outside the ≥90 gate) and add tests for the two untested hooks,
  useServerJsonImport and useImportClientConfig, bringing every hook to
  ≥90 on lines/statements/functions/branches.
- #1789: widen clients/{cli,tui,launcher} format/format:check to their
  top-level configs; add root format:shared / format:check:shared covering
  test-servers/src/**, vitest.shared.mts, and the repo-root eslint.config.js.
- #1790: pin prettier to an exact version (3.8.4, dropping the ^3.8.1
  caret) in all five package.json files so the format gate's verdict can't
  shift with an in-range patch bump; lockfiles synced.
- #1767: its root-file format+lint gap is closed here (format:shared +
  a new lint:shared via a second files block in the root eslint.config.js;
  web/server/ was already gated in #1788). Its larger cli/tui __tests__
  typecheck piece (76 type errors) is split out to #1791.

Prettier-normalized the newly-covered files (pure formatting). No runtime
behavior change. `npm run ci` green.

Closes #1785

* chore: address PR #1792 review findings

- #1789 gap: widen clients/web format to include .storybook and clients/
  launcher format to include scripts/; reformat the 3 .storybook files
  (were non-conforming under the pinned prettier 3.8.4). Audited all 885
  tracked source files — now fully prettier-clean.
- Export VALIDATE_DEBOUNCE_MS / COLLAPSE_DELAY_MS / HIGHLIGHT_DURATION_MS
  from useServerJsonImport and use them in the test instead of hardcoded
  300/1000/250 (so a tuned constant can't silently desync the test).
- Assert the symmetric renameErrors["alpha"] alongside ["beta"] so a
  one-directional collision-check regression fails.
- Comment the blank-rename test as exercising a UI-unreachable defensive
  branch (canImport gates submit).
- Un-stale the two specification/v2_ux_interfaces_plan.md references to the
  now-removed navigation.ts InspectorTab.

npm run ci green.

* docs: sync AGENTS.md format-surface description with the widened globs (#1792 review r2)

1ce3b64 added .storybook to clients/web's format glob and scripts/ to
clients/launcher's, but AGENTS.md:222 still described the pre-fix scope.
Bring it in line and note the non-recursive top-level glob is why nested
dirs are named explicitly. Docs only.

* chore: handle PR #1792 round-3 follow-ups in-place (format-coverage guard, uniform globs, theme gate)

Rather than defer these to tickets, fold them into this PR:

- Obs 2: widen every client + root format glob to a uniform
  *.{ts,tsx,mts,cts,js,jsx,mjs,cjs} so a future .mts/.cjs/.tsx top-level
  file can't silently slip the gate.
- Obs 1: add scripts/verify-format-coverage.mjs (wired into `validate`) —
  it parses the format:check globs out of every package.json, enumerates
  all tracked source files, and fails listing any not covered by a glob.
  The durable, standing version of #1789's one-shot audit; negative-tested.
- Obs 3: bring src/theme/** under the coverage gate (21/23 files were
  already ≥90 transitively; add Paper.test.tsx for the one laggard,
  Paper.ts). src/App.tsx (~4.5k lines, ~42% branches) is converted from a
  silent omission into an explicit, documented exclusion (comment on the
  coverage `include` + AGENTS.md) — gating it is a dedicated effort, not a
  whitelist tweak.

npm run ci green (the new guard reports 885/885 tracked source files gated).

* chore: address PR #1792 round-4 findings (guard hardening, docs, exclusion list)

- Harden verify-format-coverage: only harvest format:check globs from
  scripts transitively reachable from `validate` (via npm run refs), so an
  unwired/renamed format:check no longer counts as coverage. Negative-tested
  — renaming clients/web format:check to an unreferenced name now fails the
  guard (627 files flagged) instead of passing.
- Name src/main.tsx and src/index.ts (browser + bin bootstraps) alongside
  src/App.tsx in the coverage-include comment and AGENTS.md, so the
  documented exclusion list is complete rather than claiming App.tsx is the
  only one.
- Doc sync: document verify:format-coverage (AGENTS.md + README script table
  + scripts/ layout line), fix the `validate` ordering (verify:format-
  coverage now runs before validate:core) in AGENTS.md and README, and
  update the quoted globs to the uniform *.{ts,tsx,mts,cts,js,jsx,mjs,cjs} /
  test-servers *.{ts,tsx,mts,cts}.

npm run ci green.

* chore: address PR #1792 round-5 findings (airtight guard + doc/config sync)

- verify-format-coverage: assert the root `validate` chain invokes each
  client's `validate` (cd <dir> && npm run validate), closing the last
  reachability edge — a client dropped from the root chain now fails the
  guard even though its own globs still exist. Negative-tested.
- eslint.config.js: widen the shared `files` block to
  test-servers/src/**/*.{ts,tsx,mts,cts} to match the widened lint:shared
  glob, so a future .mts/.cts there is lint-gated, not just prettier-gated.
- AGENTS.md: scope the "uniform extension set" claim to client globs
  (core stays {ts,tsx}, shared {ts,tsx,mts,cts}), with verify:format-coverage
  as the backstop — removing the self-contradiction with the line below.

npm run ci green.

chore(web): format-gate the ungated first-party TS/JS (server/, vite.config.ts, scripts/) (#1788)
* chore(web): format-gate the ungated first-party TS/JS (#1778)

Prettier only covered core/ and each client's src/, leaving the web Node
backend (clients/web/server/**), web top-level configs (vite.config.ts,
tsup.runner.config.ts, eslint.config.js, ...), and the root build/verify
tooling (scripts/**/*.mjs) ungated — so their formatting was never checked
by validate/CI. eslint already reached these via `eslint .`, so this is a
prettier-only gap.

- clients/web format/format:check now cover src, server, and top-level
  *.{ts,js}, not just src.
- New root format:scripts / format:check:scripts for scripts/**/*.mjs,
  folded into the root format and into validate:core.
- Normalized the newly-covered files with prettier --write (pure
  formatting; no runtime change).

Closes #1778

* chore: future-proof the scripts format glob (#1778 review)

Widen format:scripts / format:check:scripts from "scripts/**/*.mjs" to
"scripts/**/*.{mjs,js,cjs,ts}" so a future non-.mjs file under scripts/
is auto-gated, matching the future-proof glob style clients/web now uses.
A brace glob is a single pattern, so prettier does not error on the
unmatched branches. Addresses observation #2 from the PR #1788 review.

d86d8f7 widened the scripts glob to {mjs,js,cjs,ts} and updated the
validate:core bullet, but the format bullet at AGENTS.md:217 still said
scripts/**/*.mjs. Bring it in line so the two mentions agree.
