When an authorization server returns an `id_token` alongside the access
token, the Inspector already persisted it and never showed it. Wire it
through to Connection Info as a viewer.
- Generalize `OAuthAccessTokenField` into `OAuthTokenField` (label + token),
so the ID Token row reuses the existing copy control and "Decode JWT"
toggle rather than duplicating them. Access-token behavior is unchanged.
- `oauthDetailsFromConnectionState` now surfaces `tokens.id_token` as
`idToken`, omitted entirely when absent so no empty row renders.
- Docs: update the two `specification/` references to the renamed field.
This is deliberately a viewer, not a flow: no OIDC login mode, no signature
verification, and the `id_token` is never treated as a credential. The EMA
path is untouched. `id_token` is already in `maskSecrets`'
`JSON_SENSITIVE_KEYS`, so it stays masked in the Network tab — no gap.

Copilot round 4: no new visible comments, two in the suppressed block. Both
valid.
1. The `type: [T, "null"]` encoding keeps its keywords at the top level, so a
nullable enum written that way carries the null *inside* the list:
`{ type: ["string", "null"], enum: ["envio", "recebimento", null] }`. The
collapse left it there, which broke both renderers in different ways — the
web dispatcher handed `null` to Mantine as option data, and the TUI's
all-strings check rejected the whole enum and fell back to a plain text
field. Neither is the dropdown the schema asks for.
The collapse now strips a `null` member whenever it flattens, since that
fact has already moved onto `nullable`. An enum of nothing but `null`
drops out entirely: it offers no value a dropdown could show, so the plain
widget serves the field better than an empty select. Covered in core and
end-to-end in both dispatchers.
2. The new integration test claimed in its own header to pin the registry and
config wiring, then called `createNullableFieldsTool()` directly — so a
misspelt preset case or a config naming a dead preset would have left it
green. A fair "this does not test what it says" catch. It now resolves the
checked-in `nullable-fields-http.json` through `loadConfig` →
`resolveConfig`, matching `duplicate-tool-names.test.ts`, and asserts the
resolved tool names before booting the server.

Two findings, both about the fallback accepting more than it should.
- The lenient page schema validated pagination and nothing else, so a response
carrying a malformed entry AND an unrelated top-level violation salvaged: the
entry was reported and the other violation vanished with the strict error that
caught it. The page schema is now DERIVED from the method's real result schema
with only its item array relaxed (`lenientListPageSchema`), so every other
field — `_meta`, `nextCursor`, anything a future revision adds — is still
validated. The modern era envelope the raw-wire path bypasses (`resultType`,
`ttlMs`, `cacheScope`) is checked explicitly for the same reason.
Salvage is also narrowed to `InvalidResult`: `UnsupportedResultType` means the
codec doesn't recognize what KIND of frame arrived, so it isn't a list with a
bad entry and reporting an item-level reason would hide a protocol failure.
Marking the Protocol entry still applies to both, hence two predicates.
- On every rethrow path the re-walk had already answered the method, so the
caller's own `markResponseRejected` (in `ManagedListState.refresh`) landed on
the lenient page that succeeded and left the refused response clean. The
correlation is restored before rethrowing — deleted when nothing had answered
before, so the outer mark is a no-op rather than a lie.
`nextCursorOf` / `rawItemsOf` narrow the page's fields instead of casting: the
runtime-keyed `extend()` loses the shape, and asserting it back would be exactly
the unjustified cast the last round removed.

Three findings (one inline, two in the suppressed block), all valid.
1. `toConstOptions` still stringified every non-null `const`, so
`items: { anyOf: [{ const: 1 }, { const: 2 }] }` submitted `["1"]` where
the schema says `[1]`. Same wrong-type-on-the-wire problem that keeps a
numeric `enum` off the select path, so it gets the same answer: only a
string `const` is selectable, anything else falls to the JSON editor
where the value keeps its type.
2. `hasMissingRequiredFields` derived null admission from the *renderer's*
collapse, which is narrower on purpose — it only flattens a two-member
union. So `anyOf: [string, number, null]` renders through the JSON
fallback (where `null` is typeable) yet was still marked missing,
disabling submit on a value the schema accepts. Null admission is a
validity question, not a rendering one, so it is now its own predicate:
`admitsNull` in core, recognizing `nullable`, `type: "null"`,
`type: [..., "null"]`, and a null branch anywhere in an `anyOf`/`oneOf`
of any size.
3. Nothing exercised the `record_shipment` preset — the web and TUI tests
build the `anyOf` shape by hand, which verifies the renderers but
*assumes* the premise the whole fix rests on: that Zod's `.nullish()`
emits `anyOf: [<branch>, { type: "null" }]` with the enum on the branch.
A Zod output change or a registry typo would leave every unit test green
while the documented reproduction server quietly stopped reproducing.
Added an integration test that boots the preset over HTTP, asserts the
wire shape, and runs it back through the collapse — following the
`duplicate-tool-names.test.ts` precedent, which exists for the same
reason (#1957).

silently does nothing, since a modern server can advertise `logging` and still
ignore the option.

The visible review was clean; all five findings were in the suppressed block,
two of them real defects.
- The exclusion scan's aggregate offset was wrong twice over: `excluded.length`
counts only invalid-header tools, and on page one it also folded in the
current page's valid count. A reported index therefore pointed at a position
that doesn't exist — worst for an unlabeled entry, whose index is all the user
has. Replaced with a raw-entry offset advanced by each page's valid + malformed
counts.
- The scan's own refused response was never marked. It is a distinct exchange
from the aggregate's, and the lenient re-fetch moves the method correlation
off it, so its Protocol entry rendered as a clean success the client had in
fact refused. Marked with the captured id, as `salvageList` already does.
- Three double casts in the test fixture are gone: `ListPage` now models raw
wire data (`items: unknown`, `nextCursor?: unknown`), which is what a server
built to emit spec-forbidden shapes actually serves. Declaring the validated
type and casting malformed values through it asserted the opposite of what
these tests exist to check. The cursor map narrows to `string` at the one
place a cursor addresses a page.

All four findings taken (one visible, three in the suppressed block), plus the
`excludedTools` sibling leak the round-1 reply had deferred:
- `rawItemsOf` read a missing or non-array list member as an empty page, so a
top-level violation (`{ tools: "invalid" }`) on a later page was discarded
and the call returned a silently truncated list. It now returns `undefined`
for "not a list at all", and the walk rethrows the original strict error.
- A failure of the re-walk ITSELF (a malformed `nextCursor`, a connection lost
mid-walk) escaped in place of the original error, whose response is the one
`rejectedResponseId` was captured for. The walk is now wrapped: the original
surfaces, the secondary is logged so it stays diagnosable.
- The exclusion scan's lenient fallback discarded its malformed entries despite
the comment claiming they were reported. Observable when the aggregate is
served from cache: the salvage never runs, so nothing else reports them. The
scan now returns them and `refreshExcludedTools` reports them — only ever
adding, so a clean scan can't clear what the salvage path just wrote.
- An empty-string cursor is a valid cursor, and `cursor ? {cursor} : {}` dropped
it, re-requesting page one and duplicating its entries until the
repeated-cursor guard fired. Both walks now test `!== undefined`.
- `excludedTools` had the same session leak fixed for `malformedListItems` last
round: cleared only on an explicit `disconnect()`, so the `onerror`-with-no-
`onclose` route carried the previous server's set into the next connection.
Cleared on the start-clean path too — safe because every `listAllTools`
recomputes it, so this can only drop a stale set.

Closes#2007.
Two things, both surfaced while answering "does #1928's PR also fix #2007?".
**#2007, and why it belongs in this PR.** `z.array(z.union([z.object(…),
z.object(…)]))` gives an `items.anyOf` whose branches carry no top-level
`const`, so every MultiSelect option was `String(item.const ?? "")` — the
empty string, twice. Mantine *throws* on duplicate option values, greying
out the whole tool panel.
That is a pre-existing bug, but this branch makes it reachable from a new
direction: a *nullable* array of object unions previously had no top-level
`type` and fell to the JSON fallback, and now collapses to `type: "array"`
with `items.anyOf` — straight into the crash. Shipping the collapse without
this fix would widen an existing crash, so the two go together. Both shapes
are covered by tests.
`toConstOptions` now returns `null` unless every branch yields a distinct,
non-empty value, and the field falls through to the JSON editor — which is
the honest widget for a union of object shapes anyway. Applied to the
`string`/`oneOf` path as well, which had the identical `?? ""` and the same
duplicate-throw waiting on it.
**Copilot round 2.** Round 1's fix kept "an explicit `type` is
authoritative", so `{ type: "number", enum: [1, 2] }` still collapses with
its enum hoisted. The TUI's dispatcher tests `property.enum` *before* the
type switch, and `toSelectOptions` stringifies, so that reached a select
that submits `"1"` for `1`. The select path is now gated on `isStringEnum`
(exported from core for this), and a typed non-string enum falls through to
its typed field: the enum constraint is lost, the value's type is not,
which is the safer of the two losses. Pre-existing for a plain numeric
enum; the collapse just made the nullable form reachable too.

`logging/setLevel` is a legacy-era method, but connect() called it on any
server advertising the `logging` capability, era regardless. The modern wire
era rejects it outright, and because the call sits in the post-handshake
sequence that rejection failed the *connection* — so the CLI (the one caller
passing `initialLoggingLevel`, hardcoded to "debug") could not run any method
at all against a modern server that advertised logging.
Gate it on `protocolEra !== "modern"`. Modern has no session-scoped level to
set: the equivalent is the per-request `io.modelcontextprotocol/logLevel`
`_meta` opt-in, already driven by `modernLogLevel` from the server settings.
So modern skips the call rather than translating it. Legacy is unchanged.
The guard lives next to the capability check in inspectorClient.ts rather
than in the CLI, so any future caller passing `initialLoggingLevel` is
covered too.

Three real defects it caught, plus the tests it asked for:
- The strict `tools/list` aggregate is filtered by the SDK for invalid
`x-mcp-header` annotations (SEP-2243), but the salvage path was not: one
ordinary malformed tool would trip the fallback and readmit every
invalid-header tool beside it. Salvaged tools now go through the same scan.
- `markResponseRejected` resolves "the last response received for this method",
and the re-walk answers that same method — so the mark landed on a salvage
page that succeeded while the actually-invalid response rendered clean. The
correlation id is now captured before the re-walk.
- The report was cleared only on an explicit `disconnect()`. The route out that
tears down nothing (`onerror` with no `onclose`) carried it into the next
connection, so it is now cleared on the start-clean `resetSessionState()` path
as well.
Fixing the first exposed two more, both found by the new test:
- The modern (2026-07-28) codec validates a result against the spec schema
before the caller's, so a lenient `client.request` is rejected exactly as the
strict one was — there was no salvage on the modern leg at all. It now goes
through the raw-wire channel that exists for the modern `tasks/*` methods.
`withModernEnvelope` is split out of `withModernTaskEnvelope` so a list
request doesn't claim the tasks extension the user may have disabled.
- A malformed tool also blanked the SEP-2243 excluded set, leaving a tool that
vanished for an invalid header with no explanation — #1909's own complaint one
level down. The scan walk now tolerates a malformed sibling.

Four findings, all valid:
1. Returning `T` was unsound. The collapse genuinely changes two fields —
`type` stops being an array, `anyOf` becomes `undefined` — so a caller
whose `T` typed either that way could keep treating it so afterwards.
The result is now `T | NormalizedNullableUnion<T>`, which states exactly
that: `Omit<T, "type" | "anyOf">` plus a `RenderableType` `type`, a
cleared `anyOf`, and `nullable`. The one assertion left is isolated in a
`collapsed()` helper, needed only because `Omit` stays deferred while `T`
is open.
2. A typeless `enum` does not imply strings. JSON Schema allows
`enum: [1, 2]`, and inferring `"string"` for it would hand numbers to a
`Select` declared `string[]`, and make the TUI submit `"1"` for `1`. Now
only an all-string enum earns the inference; anything else stays on the
JSON fallback. An explicit `type` is still authoritative.
3. `hasMissingRequiredFields` counted every null as missing, so clearing a
*required* nullable enum — newly possible via the clear button — would
disable submit on a value the schema permits. `required` constrains
presence, not content, so null now counts as present exactly when the
field's schema admits it.
4. `collectSchemaDefaults` read the raw union, so a default nested inside a
nullable object's branch was displayed by the form but never seeded into
the submitted values. It normalizes each property first, like the
renderer does.

Closes#2015, folded into #1928 rather than left as a follow-up.
The TUI's `schemaToForm` has the same defect the web `SchemaForm` had: its
local `JsonSchemaProperty` declares only `type?: string` — no `anyOf`, no
array-valued `type` — so a `.nullish()` argument has no top-level `type` or
`enum` for the dispatcher to read and falls to the `switch` default, losing
its select. Milder than the web bug (a plain text field, not a corrupting
JSON textarea), but the same class.
Fixing it in a second place is the argument for not having the logic in a
first place. So the collapse moves to `core/json/nullableUnion.ts` as
`normalizeNullableUnion`, generic over a minimal `NullableUnionSchema`
shape — the least a caller must expose to be *recognized* as a nullable
union — so neither client has to adopt the other's schema type. Both form
builders now share one copy and cannot drift on which schemas they render.
- `core/json/nullableUnion.ts` — the shared collapse, plus tests at
`clients/web/src/test/core/nullableUnion.test.ts` (the web suite is what
gates `core/`).
- `clients/web`: `schemaUtils.normalizeUnionType` is gone; `SchemaForm` and
`resolveRefsInMessage` call the core function directly.
- `clients/tui`: `schemaToForm` normalizes each property before dispatch,
and `JsonSchemaProperty` grows the `anyOf` / array-`type` fields the
encoding uses.
Verified by driving the built TUI under a pty against the
`nullable-fields-http.json` showcase server. Before, every argument of
`record_shipment` rendered as a plain text field; after, `direction` is a
select ("No value"), `quantity` an integer, `express` a boolean
("[Not set]").

The SDK validates a list result as a whole, so a single non-conforming entry
rejected the entire response and the panel showed "Couldn't load resources"
with zero items — the exact opposite of what a debugging tool should do with a
server that is 90% right. Reported against a PHP server whose empty
`annotations` object reaches the wire as `[]` rather than `{}`.
`listAll*` now falls back to a lenient re-walk when — and only when — the SDK
rejects a result it received (`InvalidResult` / `UnsupportedResultType`), keeps
the entries that validate, and reports the rest. A conforming server takes the
strict, cache-aware path exactly as before.
Salvaging is not accepting: the dropped entries are named with their reason in
a warning above the list, and the Protocol entry is still marked rejected, so
the wire truth survives. When every entry validates, the original error is
rethrown rather than swallowed — the rejection was about something the
per-item pass cannot explain.
`isClientDecodeRejection` moves to the new module and is now shared with
managedListState, which had the only copy.

A tool argument that is optional AND explicitly nullable — Zod's
`.nullish()` / `.nullable().optional()` — compiles to
`anyOf: [{ type: "string", enum: [...] }, { type: "null" }]`. Every branch
of the tool-call form's field dispatcher tests a single `type` string, so
such a field matched nothing and fell through to the raw-JSON fallback,
whose onChange stores the unparseable in-progress text back into state and
re-`JSON.stringify`s it on the next render — compounding a fresh layer of
escaping on every keystroke.
`normalizeUnionType` already existed for the FastMCP `string|null` shape,
but it only copied the surviving branch's `type` and dropped everything
else, so the `enum` never reached the dispatcher; and nothing called it on
a tool input schema — only elicitation requests, via
`resolveRefsInMessage`. So:
- Rewrite `normalizeUnionType` to hoist the non-null branch's own keywords
(`enum`, `items`, `properties`, `minimum`, …) onto the flattened schema,
as v1.x did. This also collapses nine near-identical blocks into two and
picks up the `object`/`array` cases the `type: [X, "null"]` form was
missing.
- Normalize each field in `SchemaForm.renderField`, so tool, elicitation,
and app forms all get it rather than just elicitation.
- Give a nullable enum `Select` a clear affordance, so a value can be set
back to `null`; a non-nullable enum keeps none, since it would reject it.
Adds a `record_shipment` preset and `nullable-fields-http.json` showcase
config serving all four nullable scalar shapes, for manual verification.

v2/main has been at 2.0.0 since the v2.0.0 release while main and npm `latest`
are at 2.2.0. The bump was created on the milestone-merge branch, which is cut
from main, so it only ever existed downstream of v2/main and nothing carried it
back — `chore: 2.1.0` and `chore: 2.2.0` are both on main and neither is on
v2/main.
That is not cosmetic. A branch cut from a milestone-merge branch silently
carries the bump into an unrelated PR — #2009 arrived with a 2.0.0 -> 2.2.0 diff
on a container bugfix — and anything reading the version in development
(readInspectorVersion, --version, GET /api/config) reported a version two
releases old.
Move the bump to v2/main, before the milestone merge, so it flows into main with
the rest of the milestone's work and the branches never disagree. The release
tag is applied to the resulting main commit instead. The publish workflow needs
no change: its tag-vs-package.json assertion runs at the release commit on main,
which still carries the bump.
Deliberately not a back-merge of main into v2/main: main holds the whole pre-v2
v1 history (~230 commits v2/main lacks, retained through `chore: replace main's
tree with v2`), so merging would graft all of it into the develop branch's log
permanently to deliver a two-file change.
Also sets v2/main to 2.2.0 as a one-time catch-up. Nothing in the repo asserts a
specific version value, so this is a safe two-file change.

Two defaults that each break the Inspector inside a container.
#1951 — the web UI never loads in a VS Code dev container. `HOST` defaulted
to the NAME `localhost`, and `server.listen(port, host)` resolves a name
through `dns.lookup` and binds the SINGLE address it gets back. Since Node 17
the default result order is `verbatim`, so on a glibc Linux host — whose
/etc/hosts maps localhost to both 127.0.0.1 and ::1 — that is `::1`. The
server bound IPv6 loopback only and refused every IPv4 client, including the
dev container port forwarder. It presents as an endless spinner rather than a
connection error because the forwarder accepts on the host side before failing
to connect inward. Default to the ADDRESS 127.0.0.1 instead; an explicit
HOST=localhost is still honored as typed.
#2008 — the Apps tab is unreachable in any container. The MCP Apps sandbox
listened on an OS-assigned port, so it changed every run and could never be
named in a devcontainer `forwardPorts`, a `docker run -p`, or a tunnel. Default
it to a fixed 6275, mirroring CLIENT_PORT's fixed 6274, and retry once on an
OS-assigned port (loudly) if it is taken — the collision a dynamic default
never had.
Verified in the reporter's exact image

Review caught that v2_auth_ema.md contradicted itself. Its "TypeScript SDK
(implemented)" section claimed Inspector depends on `@modelcontextprotocol/sdk`
v1.x only (`^1.29.0`) and that there is "no `@modelcontextprotocol/client` v2
dependency in the tree today" — while the subsection immediately below it
documents which v2 client helpers the EMA legs have adopted.
Checked rather than assumed: every module the section's table names imports the
v2 client (emaFlow, idpOidc, resourceContext, tokenEndpoint, transportProvider,
wire, and providers.ts), and there are zero v1 SDK imports in first-party code.
The v1 SDK is present in the tree only as a peer pulled in by ext-apps, which
AGENTS.md already states must never become a direct dependency.
Rewrote the paragraph to say what is true and name the version, so it stays
consistent with the two auth specs corrected in the previous commit.
The per-row "v1 SDK" attributions in the table below it are wrong for the same
reason, but correcting each one means auditing which SDK symbol each leg calls
today — a real audit, not a version-string refresh, and out of scope for a
dependency bump. Left for a follow-up rather than guessed at here.

The SDK shipped 2.0.0 final on 2026-07-27. Shipping the Inspector against a
prerelease of its core protocol library is a supply-chain and reproducibility
liability we no longer have a reason to carry: a beta is eligible for unpublish
and deprecation in a way a stable release is not.
Bumped in the root package.json only — client, core, server, server-legacy.
Node resolution walks up, so the root install already serves every client; a
per-client declaration would install a second copy that drifts from it (#1970).
Verified after install: one copy of each at 2.0.0, no clients/*/node_modules/
@modelcontextprotocol/* at all. ext-apps is a separate package on its own ^1.7.4
line and is untouched.
The beta.5 → 2.0.0 delta is seven commits. Reviewed each for call-site impact:
- core/src/schemas.ts (+16/-16) is doc-comment only — every hunk rewrites a
spec URL from a commit-pinned GitHub blob to the published 2026-07-28 page.
No schema surface change, so nothing in core/mcp or core/json is affected.
- client 2.0.0 wants zod ^4.2.0; we are on ^4.4.3, so no zod move and no risk
of the #1896 dual-copy tsc heap blowup. verify:dep-lockstep stays green and
the lockfile delta is exactly the four packages with no transitive churn.
- fix(validators) honors declared draft-07/06 JSON Schema dialects instead of
rejecting them, which can only widen the set of tool schemas we accept.
- The SSE keep-alive and legacyWrap changes are server-side, exercised by the
test servers rather than by client code.
The one change with real behavioral reach is #2564: the negotiation probe now
classifies HTTP 401/403 as an auth failure instead of legacy-era evidence. That
is the upstream fix#1807 is blocked on, and it is left for that issue — the
directAuthRecovery clause in inspectorClient.ts still intercepts the challenge
before the classifier sees it, so this bump does not change connect behavior.
#1807 can now delete the workaround and lean on the SDK verdict, but doing it
here would smuggle an auth change into a dependency bump.
Also corrected the two auth as-built specs, which still claimed beta.4 —
already stale before this change. v2_new_spec_impact.md is deliberately left
alone: it is a dated pre-upgrade analysis, and editing its premises would
rewrite the record rather than update it.
npm run ci passes end to end: validate, the per-file >=90 coverage gate,
verify:build-gate, all six smokes (including web:app driving connect -> open
app -> data-app-status="ready"), and 472 Storybook tests.

Review was right, and I had assumed the handle type rather than checking it.
Probed both under happy-dom:
setTimeout -> typeof "object", constructor Timeout
requestAnimationFrame -> typeof "object", constructor Immediate
So `typeof id === "number"` in the clearTimeout wrapper never matched, and an
explicitly-cleared timer was never untracked. Both `Set<number>` annotations and
`const id: number` were fictions TypeScript could not catch, since the DOM lib
DECLARES number while happy-dom RETURNS an object.
The effect was benign — the teardown sweep re-clears them and clearTimeout is
idempotent — but the sharper problem is that the test asserting this passed for
the wrong reason. "clearTimeout doesn't throw" holds whether or not tracking
works, so it proved nothing and hid the broken guard.
Hold handles as `unknown`, route cancellation through two small helpers that
carry the one justified cast each, and drop the numeric guards. The test now
asserts the net's own bookkeeping through an exported pendingTimerCount(), and
is mutation-checked: restoring the numeric guard fails it (1 failed | 6 passed).
That is the second test in this PR that passed without proving its claim. Both
had the same tell — the assertion would have held with the feature removed.

Review caught a second-order effect of the fix: making the leaked-timer net
global invalidated the rationale of a neighbouring rule.
"Do not hand-roll a bare MantineProvider — that reintroduces the leak class"
stopped being true the moment the net moved into setup.ts, which covers every
unit test regardless of how it renders. The rule itself is still right, so keep
it and replace the justification: a hand-rolled provider skips the project theme
and the helper's options and drifts from every other test. Both copies say
explicitly that the old reason no longer holds, so nobody re-derives it.
Mirrored into .github/copilot-instructions.md in the same PR, as AGENTS.md
requires for review-relevant guidance — it carried the identical stale claim.
That makes four places this one belief had propagated to. A fix can create stale
docs by making a previously-true statement false, which is easy to miss when
only the changed lines get read.

Review feedback on #1987: `waitForDeadTransport` polled `/api/mcp/send`,
which answers `transport_error` from two branches — the `isTransportDead()`
short-circuit and the `catch` around a rejected `send()`. Only the first
implies the transport is marked dead, so the stop condition could not tell
them apart from the response alone.
That was safe in practice: `StdioClientTransport.send` rejects only when
`_process` is undefined, and the transport clears `_process` and calls
`onclose` in one synchronous block, so the `catch` branch is not observable
before `markTransportDead()` has run (confirmed empirically — 0/25 probes
returned early). But the safety rested on an SDK-internal ordering this test
neither states nor controls, and if it changed the send test would silently
cover the `catch` branch instead of the short-circuit it names — a regression
with no failing run attached to it.
Poll `/api/mcp/auth-state` instead. For a session connected without an
authState there is no auth provider, so `setAuthState` always throws and
`transport_error` there has exactly one source: the dead-transport
short-circuit. The route never awaits a transport response, so it cannot
hang either. Same cost, exact condition, no dependence on SDK internals.

Review found the net still had the exact hole it was written to close.
The afterEach is synchronous, so a queued rAF callback cannot run until it
returns — at which point it registers a fresh setTimeout AFTER the sweep has
already drained. On a file's last test that timer survives environment
teardown. That is the rAF race described in the previous commit message, left
open by the fix for it.
Track animation frames too, and cancel them BEFORE sweeping timers. Order is
the fix: JS is single-threaded and nothing between the two loops yields, so no
frame callback can run in between. Mutation-checked — without the cancel pass
the new ordering test fails (1 failed | 6 passed); with it, 7 pass.
Also from review:
- renderWithMantine.tsx still documented the disproven env="test" behavior. It
is the file contributors are told to use, so leaving it would have preserved
the wrong belief exactly where it does most damage. That was the third copy of
this claim in the repo; all three now corrected.
- Dropped an unjustified `as unknown as` in the test helper, which broke the
repo's own double-cast rule. Inference keeps the handle type clearTimeout
accepts.

connectDeadSession spawned a real node subprocess whose only job is to die,
then slept a flat 300ms for the death to propagate. That budget has to cover a
cold spawn(), node's startup, its exit, the parent observing the close, and
onclose marking the session dead — comfortable on an idle box, not under CI
contention or a machine running several agents.
When the budget was missed the session was still live, so isTransportDead() was
false and /api/mcp/send fell through to `await responseWait` for a tools/list
reply the dead child can never send. Nothing bounds that wait, so the test hung
to the project's full 30s ceiling. The timeout IS the symptom of losing the
race, which is why it never presented as a clean assertion failure.
Poll the observable condition instead. Two design points that are load-bearing:
- The probe is a NOTIFICATION (method, no id). requestIdForSendWait returns
undefined for it, so the route never awaits a response and cannot hang.
Probing with a request would reproduce the exact bug being fixed.
- Not /api/mcp/events, which looks like the natural "transport died" signal:
opening that stream on a dead transport calls sessions.delete(sessionId),
so the send under test would then answer 404 instead of transport_error.
Both terminal branches of the route answer transport_error — the
isTransportDead() short-circuit and the catch around a send() that threw on the
dead pipe — and either proves the subsequent real send cannot reach the hanging
path, so both are valid stop conditions.
Verified by reproducing the bug deterministically: with the wait reduced to 0
(the budget always missed) the test times out at 30s; with the poll it passes
10/10. Fixing the helper rather than the test also covers its second call site,
the auth-state test, which sits on the same race and had simply not lost it yet.
connect-crash.test.ts:147 is deliberately left alone. #1985 proposed giving it
the same treatment, but readSseEvents stops at transport_error, which arrives
whenever the child dies — so its 200ms sleep cannot hang, and changing it would
add risk for no gain.

Review follow-up on #1983. Copilot was right, and about a hazard this repo
had already proven and then documented away: the claim that ink's ">=19"
peer "keeps npm from hoisting it next to a React the Inspector couldn't
also use" is false. A consumer pinning React 19.0 satisfies ">=19" while
`^19.2.4` nests underneath, so ink renders through their React and the
bundle through ours — the #1952 crash, one level up, breaking TUI startup
rather than just its forms.
Bundling ink closes it (verified: with a `createRequire` banner for the
inlined CJS, since react-reconciler calls `require("react")` and
signal-exit@3 `require("assert")`), but costs ~1.4MB — react-reconciler
and yoga-layout come along. The root `react` range closes it for free
instead: `^19.0.0` is open to the whole major, so npm can satisfy our
React and a consumer's pinned React 19 with one copy, and an external ink
resolves the same copy the bundle does.
Verified against both consumer trees — the reporter's (React 18 + ink 5)
and a pinned React 19.0.0 + ink 6.8.0, which splits under `^19.2.4`.
That makes the range load-bearing while looking like an ordinary version
bump, so the tests pin it: the root range must equal ink's own declared
peer floor. They also assert each exempt package is both external and a
root dependency — external means consumers install it, the mirror image
of the inlined ones, which must not be root-declared.
The docs in all four places now say ink is exempt on cost and never on a
peer range, and name that claim as one we got wrong.

A window.setTimeout that outlives its test file fires after happy-dom disposes
that file's window; React's dispatchSetState then throws an uncaught
ReferenceError: window is not defined. Vitest attributes it to whichever file
was running, so a single leak fails the ENTIRE run with every test passing —
landing on an innocent file under a step named "Enforce per-file coverage gate."
Seen twice in CI, both on docs-only branches.
Not a Mantine bug, and not a badly-written test. Both hooks do clear on unmount
(useTransition's clearAllTimeouts, useLockScroll's effect cleanup). It is a rAF
race: clearAllTimeouts cancels the *pending* rAF, but the transition schedules
rAF -> rAF -> setTimeout, so if the inner callback is already in flight when the
unmount lands, cancelAnimationFrame is a no-op and that callback then schedules
a timer after cleanup has run. Nothing owns it. Needs a loaded machine, which is
why it only ever appeared in CI.
Track every timer and clear whatever is still outstanding after cleanup(). The
ordering is load-bearing: legitimate unmount cleanups get their turn first, so
only true leaks are dropped. Fake timers pass through untracked, which is
correct — a fake timer cannot outlive the environment.
Also corrects the claim, in AGENTS.md and in setup.ts's own comment, that
env="test" prevents this. It does not: env is read only by Transition.mjs at its
render branch, while useTransition runs before that check (hooks cannot be
conditional) and still schedules real timers. Measured — opening a <Modal>
through renderWithMantine schedules three 200ms timers. Believing that guarantee
is why this went unexamined.
The regression test is mutation-verified: with the net disabled it fails, with
it restored it passes. It deliberately does not assert that Mantine schedules no
timers — it does, and that is normal; the contract is that none survive.

Review follow-ups on #1983 (Copilot's suppressed comments).
Removing `ink-form` from the root dependencies left `overrides.ink-select-input`
with nothing to override: no root dependency reaches that package any more, and
the regenerated lock carries no entry for it. The override that matters lives in
`clients/tui/package.json`, where the build resolves `ink-form` — and it is what
puts `ink-select-input@6` (rather than the React-18-era v5) into the bundle.
The README paragraph above the new bundling section still described the Ink
components and `App.tsx` as an interim coverage exclusion. #1501 lifted that:
`vitest.config.ts` now gates all of `src/**`, excluding only the pure
`src/tui-servers.ts` re-export. Corrected to match the config it describes.

Review follow-ups on #1983.
The patch's tests called the string helper directly, so nothing exercised
the esbuild `onLoad` filter that decides whether the helper runs at all. A
filter that stopped matching would leave the build green, the tests green,
and the typo shipped — the silent no-op the throwing helper exists to
prevent, reintroduced one level up. The plugin is now driven the way
esbuild drives it (register, then invoke) against the real `ink-form`
module path, and a second test pins the filter's scope: it matches that
path and a Windows-separator one, and rejects `Form.js`,
`ink-select-input`'s own `SubmitButton.js`, and a first-party
`src/SubmitButton.jsx`.
The plugin type came from `import type { Plugin } from "esbuild"`, but
`esbuild` is tsup's transitive dependency, not one this client declares —
it typechecked only while npm happened to hoist it, and would break on a
lock change that nested it. Derive it from tsup's own
`Options["esbuildPlugins"]` instead of adding a dependency for a type.

Round 5 was right on all three counts. Read dcoapp/app/lib/dco.js this time
rather than the README, which is where the earlier errors came from:
const authors = [commit.author.name, commit.committer.name]
const emails = [commit.author.email, commit.committer.email]
if (isMerge || ...) continue // parents.length > 1
else if (author && author.type === 'Bot') continue
So, corrected:
- Scope. Merge commits and bot-authored commits are skipped, not gated. "Every
commit" overstated it and could prompt a needless history rewrite.
- Matching. The trailer may match the author OR the committer, not the author
alone. A cherry-picker's own signoff is accepted.
- Certification. The DCO expressly covers submitting work created by others
that you have the right to submit, so signing off a cherry-pick is legitimate.
My "never sign off someone else's commit" would have told a maintainer not to
do a correct thing. The real prohibition is narrower: never fabricate a
trailer in another person's name.
This also retracts the mechanical argument in bd6c1072 for dropping the hook —
it does satisfy the check, since you are the committer. The recommendation
against it stands on honest grounds now: the trailer is a certification, a hook
makes it for every commit automatically including work merely applied on
someone else's behalf, and it provably cannot tell the difference. A judgment
about deliberateness, not a claim that it breaks.
Mirror corrected to match.

The hint under a form with unfilled required fields reads "you have not
competed yet". The string is upstream's, hardcoded in
`ink-form/lib/SubmitButton.js` with no prop to override it, and `ink-form`
was last published in 2024 — but it renders in the Inspector's tool,
prompt, and resource test forms, so it is ours to fix in practice.
Bundling `ink-form` (previous commit) is what makes it patchable: an
esbuild `onLoad` hook rewrites the label as the file enters the bundle.
The hook throws when the string is absent rather than passing the source
through, so an `ink-form` upgrade cannot silently retire the patch or
leave it aimed at a string that no longer exists — the tests drive it
against the real dependency source for the same reason.
Reported upstream as lukasbach/ink-form#14.

Round 4 was right that the hook signs with the configured identity while the
DCO check requires a trailer matching the commit *author*, and that the two
diverge on cherry-pick and `git commit -c`.
I tried the suggested author-aware guard and it does not work: inside
prepare-commit-msg, `git var GIT_AUTHOR_IDENT` returns the config identity, not
the preserved author. Verified end to end — cherry-picking Bob's commit as
Alice yields author=Bob, committer=Alice, `Signed-off-by: Alice`. That commit
both still fails the gate and certifies work Alice did not write, which is the
one thing the last bullet of this section forbids.
Three review rounds have now found three holes in this hook, each fix opening
the next. That is a wrong mechanism rather than an unfinished one, so the hook
is out. A subtly-broken hook in the file that governs how this repo is worked
on is worse than no hook.
The bullet now recommends `git commit -s` and names BOTH false automations —
`format.signOff` and the hook — recording the cherry-pick finding so the next
person doesn't rediscover it, and pointing anyone who wants automation at a
layer that actually knows the author. Mirror updated to match.

`ink-form` and `ink-scroll-view` were externalized by the TUI bundler and
both declare a loose `react` peer (">=18"). Installed under a project that
has its own React 18, npm hoists them to that project's root — where the
peer is satisfied — while the Inspector's React 19 nests underneath. The
bundle then renders through React 19 while those two call hooks on React
18, whose dispatcher is null, so opening a tool test form (or any scroll
view) dies with "Cannot read properties of null (reading 'useState')".
Inline them instead: their `import "react"` is emitted into the bundle and
so resolves from the build directory exactly like the bundle's own, with
npm's placement no longer part of the decision. This also pins their
transitive deps to what this repo resolved — notably `ink-select-input@6`
via `overrides`, which npm ignores for a package installed as a dependency,
so consumers were getting the React-18-era v5.
`ink` stays external: it can't be bundled (its CJS `signal-exit@3` fails
ESM interop with `Dynamic require of "assert"`) and doesn't need to be —
its ">=19" peer keeps npm from hoisting it next to an unusable React.
Both packages are dropped from the root `dependencies`, since the tarball
now ships their code rather than having consumers install them.
`clients/tui/__tests__/tsupConfig.test.ts` is the durable guard: the
failure is invisible in this repo and in every smoke (a dev install has
one React) and only appears once the package is installed under another
project, so the invariant is asserted against the config instead — every
dependency declaring a `react` peer must be bundled unless exempted.

Two claims were wrong, both verified against the app's own documentation
(dcoapp/app): "The DCO also creates an override button for users with write
access to the repository to create a successful check."
So "there is no per-PR override" and "there is no non-rewrite escape hatch"
were both false, and a maintainer following them would conclude that rewriting
history was the only way to unblock a PR.
Documented, but deliberately not as a repair. The override only silences the
check; it does not make the author certify anything, and the certification is
the whole point of a DCO signoff. Using it on your own unsigned commits asserts
nothing while looking like compliance — so the text says to treat it as
unavailable and sign the commits instead.
The same source confirms two things the doc already claimed: remediation
commits are disabled by default, and the trailer must match the commit author's
email (which is what the identity-aware hook in 6899e0ae exists for).
