Addresses Copilot review round 2. A reverse proxy routes a public address to
one stable port, so neither MCP_SANDBOX_FULL_ADDRESS nor
MCP_APP_ORIGIN_FULL_ADDRESS is used when the listener's port is OS-assigned:
an explicit 0, a config-time collision resolved to 0, or the EADDRINUSE
fallback. Validation warnings also stop echoing the URL path.

The legacy and auto e2e cases both connect to the legacy stdio fixture
whether or not the flag reaches negotiation, since auto falls back. Run
initialize against an HTTP test server that rejects the legacy handshake:
the default must fail, and --protocol-era modern must connect and report
the 2026-07-28 protocol version. Deleting the serverOptions assignment in
cli.ts now fails this case (Copilot review, PR #2372).

An ad-hoc --server-url / command launch always negotiated the legacy era,
because protocolEra was only settable per server in mcp.json. A wrapper
that mints a short-lived bearer token therefore had to write that token to
disk to exercise a server under auto or modern.
--protocol-era <legacy|auto|modern> now feeds settings.protocolEra in all
three clients through a shared parseProtocolEra coercer:
- CLI/TUI overlay it in loadServerEntries alongside --header, onto an
ad-hoc target and onto a --catalog/--config entry for that run.
- Web stamps it on the in-memory ad-hoc entry, which the backend lifts
into settings like headers; as with --header it is rejected alongside
--catalog/--config, but unlike --header it applies to stdio too.

Add MCP_SANDBOX_FULL_ADDRESS and MCP_APP_ORIGIN_FULL_ADDRESS so a reverse
proxy or ingress deployment can advertise the sandbox proxy URL and the
_meta.ui.domain app origin the browser actually reaches, instead of the
bind-derived http://localhost:<port> ones. The process still listens on
MCP_SANDBOX_PORT / MCP_APP_ORIGIN_PORT.
Both values are validated in public-address.ts and refused (warned, bind-
derived address kept) when malformed or when their origin collapses onto
the Inspector UI's (or, for the app origin, the sandbox's) — the MCP Apps
spec requires host != sandbox origin, and the single-hostname proxy layout
is exactly the one that breaks it. Plain http under an https UI is warned.
The sandbox proxy page's referrer check was a hardcoded
http://localhost|127.0.0.1 pattern no https embedder could match. It now
compares the referrer's parsed origin against an exact list injected by the
controller, derived from the same filtered allow-list as its frame-ancestors
header, with the old loopback check kept only as the no-list fallback.

`skill://data-analysis` has an authority and an empty path, which RFC 3986
permits, but the guard required a pathname starting with "/". A server echoing
the skill root back in a directory read was therefore labelled "outside this

rejected; a path-less root still names no skill file, so it fails every check

unanswered requests, which is the state to keep reporting.

A request timeout used to surface as a bare `Request timed out`. Every
fact needed to explain it was already in-process: what the client was
still waiting on, when it last heard back, and the state of the
standalone GET notification stream. The SDK's timeout now rejects with
all three, and the same snapshot is shown live in Connection Info and
on the Network entry for the stream.
- core/mcp/connectionDiagnostics.ts: the snapshot type, its one-line
description, and `annotateRequestTimeout`, which rebuilds the SDK's
per-request timeout with the state at that moment.
- InspectorClient decorates the SDK Client's `request` (the one funnel
every verb goes through) so the annotation covers the whole surface;
tracks outstanding requests with their send time, the last response,
and the most recent long-lived transport stream; exposes
`getConnectionDiagnostics()` and `connectionDiagnosticsChange`.
- fetchTracking watches a long-lived stream through a tee'd clone,
counting SSE events and reporting the close, via a new
`updateStream` callback wired through the node transport, the remote
session (`fetch_stream_update`), and the browser transport.
- FetchRequestLogState patches `entry.stream`; the Network entry's
placeholder reports the event count and open/closed state.
- Connection Info gains a Connection Activity section, ticking while
open (`useTickingClock`).

The web client drives its MCP Client through a two-hop relay
(RemoteClientTransport -> Node backend -> upstream transport). The relay
added two request-response waits that the direct transports don't have —
the backend's RemoteSession.waitForRequestResponse and the browser's
RemoteClientTransport.waitForSseResponse — and both were hardcoded to 60s
and blind to notifications/progress. The SDK Client's own request timeout
resets on progress (resetTimeoutOnProgress, which the Inspector enables),
but the relay's progress-blind waits fire first and shadow it, so a
long-running tool that reports progress is cancelled at 60s on the web
client alone while it completes over the CLI/TUI and other MCP clients.
Reset both relay waits on a notifications/progress whose progressToken
matches the pending request id, mirroring the SDK's resetTimeoutOnProgress.
A shared browser-safe progressTokenOf helper extracts the token. Log
messages (notifications/message, i.e. ctx.info) deliberately do not reset
the deadline, matching the SDK and every other client.

connectionTimeout defaulted to 0, which InspectorClient.connect() read as
"no bound at all" — so out of the box nothing the Inspector owns bounded a
connect attempt, and the only thing ending a hung handshake was the SDK's
60 s per-request timeout on initialize, reporting "Request timed out".
- Add DEFAULT_CONNECTION_TIMEOUT_MS (30000) to core/mcp/types.ts. An absent
value resolves to it on the client, on disk read, in the web form draft,
and in the CLI's header-only settings shell. An explicit 0 keeps its
documented meaning (no timeout; --connect-timeout 0) and is now persisted
so the opt-out round-trips; the default is the omit-sentinel, as for
taskTtl.
- Key the post-timeout transport teardown to the timer actually firing, not
to connectionTimeout > 0 — otherwise a non-zero default would tear down
every failed connect, including a recoverable 401 whose transport the
auth recovery holds open.
- The timeout message names the bound and where to raise it: "Connection
timed out after N ms. To accommodate a slower server, you may increase
the timeout value in Server Settings."
- The CLI's UNREACHABLE classifier now matches that message.

Every site tagged `ext-apps#702` carried a workaround for ext-apps
peering on the v1 SDK while the Inspector runs v2. With 2.0.0 the
package's `AppBridge` extends the v2 `Protocol`, takes the v2 `Client`
and `Implementation` directly, and registers its list-changed forwarding
on that client with `setNotificationHandler("notifications/…", handler)`,
so:
- core/mcp/apps.ts: `getToolUiResourceUri(tool)` takes the v2 `Tool`
without a cast; `UiMetaShape` is replaced by ext-apps' own
`McpUiToolMeta` / `McpUiResourceMeta`, which resolve under NodeNext
since ext-apps#705. `AppInfo.csp` / `.permissions` / `.visibility`
take the named types too.
- core/mcp/inspectorClient.ts: `getAppRendererClient()` returns the SDK
client itself; the Proxy that translated the 1.x schema-first
`setNotificationHandler(Schema, handler)` into the method-string form,
its `notificationMethodFromSchema` helper and its cached field are
gone. `AppRendererClient` is now `Client` rather than `unknown`.
- createAppBridgeFactory.ts: `new AppBridge(client, HOST_INFO, …)` with
no `as unknown as`; `resolveSourceUri` passes the tool straight through.
- AppRenderer.tsx: `sendToolResult(result)` — its params ARE the v2
`CallToolResult` now.
- requestAppElicitation.ts: the double cast on the `elicitation/create`
send goes too — v2 `Protocol.request` takes the standard `Request`
shape, which `ElicitRequest` is. The helper itself stays: ext-apps#733
is not in 2.0.0.
- core/mcp/extensions.ts: `MCP_APP_MIME_TYPE` re-exports ext-apps'
`RESOURCE_MIME_TYPE` from `/app-bridge`; `UI_EXTENSION_KEY` stays
hardcoded because `EXTENSION_ID` is still `/server`-only in 2.0.0.
Tests: the Proxy-translation test is removed with the Proxy; the
`getAppRendererClient` tests assert the real `Client` instance and that
disconnect withdraws it; the `useInspectorClient` sentinel is a real
(unconnected) `Client`. Comments that cited ext-apps 1.7.5 now cite 2.0.0
where the fact still holds (#733 still unreleased).

The "Long Skill Document" story compared the section heights before and
after a collapse-then-reopen of the Skill Resource panel, and #2291 wrapped
the second sample in a `waitFor` on the reading that the first was fine and
the second was taken mid-layout. It was not: `[…, 155, 285]` is the layout
with the Frontmatter section showing `CodeHighlight`'s plain `Code`
placeholder (a 57px `<pre>`), and `[…, 178, 262]` is the same layout once
the lazily imported Prism runtime and YAML grammar have landed and the
highlighter has replaced it (an 80px `<pre><code>`). Both are settled; the
section's content changed between the two samples, so no retry converges.
Whether the swap has happened when the story reaches its first sample
depends on how long those dynamic imports take. On a quiet machine an
earlier story in the file has already loaded them; under the gate's load
they land between the samples. Running the story on its own, so the cache
is cold, reproduces the failure deterministically: 3/3 red with the exact
four numbers from #2350, 3/3 green with this change, 3/3 red reverted. The
whole storybook project under a concurrent unit-suite load (load average
38-51) is 3/3 green with it.
The wait's budget is stated at the site: three dynamic imports through the
Vite server every story iframe shares measure 100-150ms cold on an idle
server and exceeded Testing Library's 1000ms default under load, so it
takes the same 10s the Ace-worker wait in `JsonObjectInput.stories.tsx`
carries, under the project's 15s `testTimeout`.

`local:gate` ran every client's unit suite bare inside `validate` and
again instrumented inside `coverage` — ~80s of a ~370s run re-executing
exactly the files the coverage pass runs a few minutes later. CI pays
nothing for that duplication because its two jobs run in parallel; the
gate runs serially, so it paid all of it.
The gate's first stage is now `local:validate`: the same `validate:guards`
and `validate:core`, then each client's new `check` script (`format:check`
+ `lint` + `typecheck` + `build`) instead of its `validate`, which is now
literally `check && test`. `npm run validate` and both CI jobs are
unchanged; `local:validate` sits in the `local:` namespace so the
workflow guard keeps it out of CI by construction.
The "strict superset" claim in AGENTS.md is reworded to what is now
true — every CI *check*, not every CI *invocation* — with the reasoning:
`@vitest/coverage-v8` reads V8's precise-coverage profiler and rewrites
no source, so the instrumented pass runs byte-identical code and is only
slower, the stricter direction for the failure class this repo sees.
Measured on the same worktree: 370s -> 262s wall (EXIT=0 both), the
four removed legs summing to 78.5s in the baseline run's own profile.

The storybook project's optimizeDeps now comes from
`getStorybookOptimizeDeps()` in `vite-base-config.ts`, beside the dev-server
helper it mirrors, so the `force` flag and the base include/exclude it carries
are asserted by `vite-base-config.test.ts` rather than living only in an
inline object a config refactor could drop.

Vite keys the Storybook project's dep cache on the lockfile and the config,
never on what the story graph imports. After a story or component gains an
import of an already-installed package, the cached bundle is still "valid",
Vite skips the scan, and the first request for the new package re-runs the
optimizer mid-run: the browser hash is bumped, a full-reload is sent that the
Vitest tester iframes ignore, and the `@storybook/react` renderer already
loaded in a live iframe keeps the old `?v=` for its lazy
`import("@storybook/react-dom-shim")`, so every story that iframe renders from
then on fails with "Failed to fetch dynamically imported module". The next run
is green because the cache has caught up.
`optimizeDeps.force: true` on the storybook project discards the cache up
front so the scanner crawls every story entry before the browser opens — the
cold path CI already takes on every PR. Measured: stale-cache 6/6 red on the
baseline, 6/6 green with the fix, 3/3 red reverted; ~0.8s per run.
Closes#2340

Round 8 of the review asked for an AST. That was the right diagnosis of the
wrong problem: the question was never which parser to use, it was why a
test-timeout guard was parsing JavaScript at all.
It got there one reasonable step at a time. The guard enforces two rules no
Vitest config can report — a per-test `retry`, and Testing Library's
`asyncUtilTimeout` — so it read them out of source text, and the review found a
new valid spelling it missed in five consecutive rounds: a trailing comment,
nested parens in `it.each([makeCase()])`, a member-access prefix, the shorthand
`{ retry }`, an aliased import, a non-literal title. Each fix was correct and
each made it more parser-shaped, until it carried eight helpers doing quote
tracking and bracket balancing.
Both rules are observable at runtime, exactly:
- `vitest.setup.shared.mts` is loaded by all six projects and reads
`ctx.task.retry` — the value Vitest resolved for the test. That covers
strictly more than the scan did: a per-test option, a `describe` option
inherited by children, a project-level setting, and a `--retry` flag typed at
a command line, which the scan could never see since it only read npm scripts.
- `clients/web/src/test/asyncUtilTimeout.test.ts` asserts
`getConfig().asyncUtilTimeout`, the value this project's own waitFors read.
Neither has a spelling to anticipate, so neither can be outrun by a new one.
Both were observed firing before being trusted.
The guard keeps only what it can answer by asking Vitest: resolved budgets,
project-level retry, config discovery, and that each project still loads the
setup file — the one thing about the runtime assertion a config CAN report.
868 lines to 361, every scanner helper gone, and 33 of 48 unit tests deleted
because they pinned edge cases of a thing that no longer exists.
storybookSetup.ts goes with it. At the library's own value its configure() call
was a no-op, and the assertion is what pins the number.
AGENTS.md gains the general rule: a rule about what the code DOES is asserted at
runtime, not read out of the source — reach for a verify:* guard when the
question is about configuration, which a tool can be asked to resolve.

No inline comments this round; all four came from the suppressed block.
The AppRenderer one is a regression I introduced by combining two changes that
were individually right. #2323 deleted that `waitFor`'s `{ timeout: 5000 }` as a
budget nested inside an equal one, which it was — and then round 2 pinned
asyncUtilTimeout at 1000, which is the exact default the site's own comment
records failing twice. The raise is restored: the enclosing budget is 15000 now,
so it is observable rather than unwinnable, and the value it beats is a measured
failure rather than a library default.
The guard could approve a configure() imported from the wrong Testing Library
copy — `cleanup` from @testing-library/react and `configure` from
@testing-library/dom satisfied two independent regexes while configuring a copy
no test calls. It now resolves the binding `configure` has in the import from
the required module, follows an alias, and reads asyncUtilTimeout out of that
call rather than out of the file. Three regression tests, including the split
import and a decoy constant elsewhere in the module.
secret-store-selection's 60s exception is hoisted to
LOCK_RETRIES_EXHAUSTED_MS, matching file-lock.test.ts, which bounds the same
wait — the new rule asks for named as well as justified.
And the testing skill still prescribed `HEADER_ANIM_MS + 200`, so a test written
by following it would have bypassed the shared slack constant this change
introduced. It now prescribes `HEADER_ANIM_MS + RAF_SLACK_MS` and says why the
two terms are separate.

The inline finding was a real bug: main() never called the discovery check, so
the deny-by-default claim rested on test:scripts happening to run the same
comparison — a different command, which `npm run verify:test-timeouts` does not
invoke. `failures` is now seeded from it, and a probe config under clients/ was
observed to fail the guard.
Three suppressed findings, all correct. The afterEach in oauth-interactive
restated the shared hookTimeout and labelled it as a round trip, when it only
stops a server and unlinks a file; it now carries no budget. The file-lock
constants were named for the opposite of what they bound — 90s covers retries
running out against a holder that never yields, 60s covers the stale-lock
takeover that succeeds — so they are LOCK_RETRIES_EXHAUSTED_MS and
STALE_LOCK_TAKEOVER_MS. The browser-timeouts header said 15 budgets; it is 19.
Separately, and more importantly: the asyncUtilTimeout raise is reverted, on
measurement. Verifying round 2 turned up intermittent 15s timeouts across
unrelated unit files, so three arms of three full unit runs were taken in this
worktree at comparable load — unmodified v2/main 3/3 green, this change with
5000 producing 1, 4 and 0 timing-out files, and the same change with that one
line reverted 3/3 green. A wait that is MEANT to expire spends its whole budget
on the happy path, so a 5x raise is a 5x cost on exactly those tests and
saturates the worker pool, starving tests that were never slow.
Both web setup files therefore state asyncUtilTimeout at the library's own
value rather than raising it, which is what #2323's rule actually asks for: a
budget nobody chose is the defect, not a budget that is small. The tests that
assert absence by letting a wait expire are the real problem and are #2335.

All nine findings taken.
Two budgets I had lowered are restored as named exceptions rather than folded
into the shared value. cli's e2e child timer goes back to 15s and the two tests
that spawn it get E2E_SPAWN_MS = 25s, so the bound carrying the diagnostic still
wins without taking load tolerance off the one suite that spawns a real process.
App.test.tsx's three-modal sequence keeps THREE_MODAL_SEQUENCE_MS = 20s — a
value chosen against an observed failure, which the shared ceiling would have
replaced with a general one.
Three real false-positive paths in the guard are closed. It now discovers every
Vitest config under clients/ and fails on one it is not configured to check —
without which "a project with no row is an error" was vacuous, since an
undiscovered config yields no project to reject. It strips comments before
looking for configure() and requires the exact expected value, so neither a
commented-out call nor asyncUtilTimeout: 1 passes. And it compares each
resolved project's setupFiles against the site it claims to configure, so
deleting a setupFiles entry can no longer leave both projects reported as
configured while Testing Library silently reverts to 1000ms. Each has a test,
and the setupFiles check was observed to fire against a real deletion.
Three stale comments the change had invalidated: main.yml still counted four
durable guards, PreviewAnnotations.stories.tsx still said the storybook project
had no setupFiles, and the new AGENTS.md rule read as though no Group F row had
been settled when this PR settles F6. browser-timeouts.test.mjs gains the
purpose header this repo's files carry.
