Copilot review round 8 (its one suppressed finding; no new inline comments).
The `boolean-schema` suggestion for a bare `true` said the replacement
"narrows the schema deliberately". That holds in an ordinary property
position and inverts under a negating parent: `{"not": true}` rejects
every value, so swapping in `{"type": "object", …}` leaves the parent
rejecting only objects and every non-object then passes — the enclosing
contract is widened. Under `if` it redirects which branch applies rather
than tightening anything.
- Parent-aware advice under `not`: suggest `{}`, which is the exact
object form of `true` and is already exempt from `untyped-schema` in
that position, with the message saying why a concrete type would be
wrong there.
- Everywhere else, and in the `untyped-schema` suggestion too, describe
the replacement as a deliberate CHANGE of contract rather than a
narrowing. A suggestion has no business claiming an effect it cannot
guarantee across the positions it can print from.
Tests pin the `not`-specific advice and assert no bare-`true` suggestion
in any of the three positions contains "narrow". The CLI README's sample
report is re-captured from a real run.

Copilot review round 7.
- Add `contentSchema` to the traversal. It holds the schema the decoded
string content must satisfy, so a bare `true` or a remote `$ref` under
it is a real finding all three clients were walking past. Also admit
the three content keywords to `CONSTRAINING_KEYWORDS` on the same
documented grounds as `format` — annotation-only by vocabulary, but
plainly an attempt to constrain, so reporting such a schema as
accepting anything would be noise. The comment now names that
category rather than singling `format` out.
- Make `handleError` async and await the envelope write. Round 6 made
the `--strict` report await its write and stopped one line short: the
envelope emitted for the very same throw still raced `process.exit()`,
so the machine-readable line a CI caller parses could be lost on a
pipe. The launcher's comment claiming the envelope was "well inside
the pipe buffer" was wrong reasoning and is replaced — fitting in the
buffer says nothing about whether the write was performed. Its call
site now awaits; the bin's `.catch(handleError)` needed no change.
- The CLI README called its sample block the "complete output" when the
error envelope follows it on every non-zero exit. Now scoped to "the
complete report", with the envelope named and linked.

Copilot review round 6.
- Share one traversal between `walk` and `declaresAnyId`. The `$id` guard
added last round descended through EVERY object value, including
instance data — `examples: [{"$id": "x"}]`, a `default`, a `const` —
where `$id` is a payload key declaring no embedded resource. Reading
one there suppressed `remote-ref` for the whole document, turning last
round's false-positive fix into a blanket false negative. Both passes
now go through `forEachSubschema`, driven by the same keyword tables,
so they cannot drift about what counts as a schema position.
- Await the stderr writes. `writeSchemaLintReport` used a bare
`process.stderr.write`, but both CLI exit paths call `process.exit()`
as soon as the work returns, which discards anything still buffered on
a piped stderr — truncating or losing the multi-block `--strict`
report on exactly the redirected-output runs a CI caller uses. Added
`awaitableError` beside the existing `awaitableLog` and awaited it.
The test's fake defers its callback so a synchronous one cannot make
the assertion vacuous; two existing stderr stubs that never invoked
their callbacks were fixed in the same pass.
- Show the CLI README's sample report in full. It printed one error
block immediately followed by the summary, a shape the formatter
cannot produce — every finding gets a block. Captured from a real run.

Copilot review round 5.
- The sidebar tooltip applied `hasError` to the TOTAL, so a tool with one
error and three warnings announced as "4 schema portability errors" —
a defect the previous round introduced while adding that wording, and
worse than the vague text it replaced. Both the tooltip and the
accessible label now carry the breakdown, formatted by a new shared
`summarizeToolFindings` so the fourth place to phrase a severity count
cannot drift from the other three.
- Suppress `remote-ref` when the document declares an `$id` anywhere.
`$id` establishes a base URI, so with a root `$id` of
`https://example.com/root` the ref `https://example.com/root#/$defs/x`
resolves to THIS document and needs no fetch — the finding and its
"inline the referenced schema" remediation would both be wrong.
Classifying correctly needs full RFC 3986 resolution against nested
embedded resources, which this module does not do, so it declines
rather than guessing. A missed finding is the acceptable direction.
- Run the `--strict` validations before every short-circuit return.
`servers/list`, `servers/show`, `--list-stored-auth` and
`--print-handoff` all return from `parseArgs` before any connect, so
the checks further down let `--strict --method servers/list` succeed
while silently ignoring a tools/list-only flag.

Copilot review round 4.
- Add `SCHEMA_UNPORTABLE` to `codeForExit`. `CliExitCodeError` lets a
caller omit the envelope, so without the case an envelope-less throw
reported the generic `error` — the same silent mislabelling the rename
was meant to prevent, one layer down. Covered via the envelope-less
construction that exposed it.
- Keep a local `type` (and the preset's `required`) alongside the remote
`$ref` in the showcase config. The TUI's `schemaToForm` dispatches on
`type`, so a `$ref`-only property fell through to a string field that
`add`'s numeric handler then rejected — making the README's "every
showcase tool is runnable" claim false there. The `remote-ref` finding
is unaffected, since that rule reads `$ref` independently.
- Restrict `type-union` to well-formed unions: non-empty, unique, and
all recognized JSON Schema type names. Its message asserts the
construct is *legal* JSON Schema, which is false for `[]`, `[3]` or
`["bananas"]`, and the `anyOf` it suggested for those would be invalid
too. Malformed schemas stay the SDK parser's business.
- Drop `if`/`then`/`else` from the presence-only allowlist. They only
constrain as a pair, so `{"if": {"const": 1}}` accepts every value and
was evading `untyped-schema`; the pairing is now checked explicitly.
- Distinguish the web sidebar severities by SHAPE, not just colour — a
circle for an error, a triangle for a warning — and name the severity
in the tooltip. Colour alone left a colour-blind reader unable to tell
them apart.
- Fix the stale "across 2 tools" count in the CLI README's hint sample.

Copilot review round 3.
- Rename the `--strict` failure from "invalid" to "unportable"
(`EXIT_CODES.SCHEMA_UNPORTABLE`, envelope `schema_unportable`, and the
message text). The module argues at length that these schemas ARE
valid JSON Schema and are merely refused by some clients, so a
machine-readable code of `schema_invalid` told automated callers the
opposite. Done now, while nothing depends on it.
- Add a fixture-path integration case. Every other test built a
`ServerConfig` by hand, so `resolveConfig`'s `rawToolSchemas`
forwarding was uncovered and `unportable-schemas-http.json` was loaded
by nothing — the shipped fixture could have lost its overrides with
the suite still green. It now goes through loadConfig/resolveConfig
and asserts the exact per-tool verdict the README claims.
- Refresh the CLI README's sample output, which still showed the
pre-round-2 wording and fixture, and so dropped the contract warning
that rewording existed to add. Captured from a real run rather than
written by hand, plus a paragraph making the suggestion pattern
explicit.
- Drop the self-referential "[Try it](#unportable-tool-schemas)" link in
the root README, which pointed back at its own section.

Copilot review round 2.
- Remove `non-object-root` entirely. It could never fire: the SDK types
`inputSchema` with `type: literal("object")`, so a tool with any other
root fails `ListToolsResultSchema` and `salvageListItems` drops it
before any client sees it. Verified against a live server advertising
`inputSchema: {type: "array"}` — `listAllTools()` returns []. A rule
that cannot fire is worse than none, because the docs then claim a
check the tool does not perform; the condition is already reported
through the malformed-items surface. Pinned by an integration test so
a change in that behavior is a signal rather than a silent gap.
- Fix the bare-`false` suggestion. `properties: {a: false}` forbids the
property; deleting the entry *permits* it with any value under the
default `additionalProperties`, so the advice inverted the schema it
replaced. Now recommends `{"not": {}}` and says why deletion differs.
- Exempt `not`-parented schemas from `untyped-schema`, so the `{"not":
{}}` above does not trip this module's own rule — under negation an
always-accepting subschema means always-reject, making "accepts any
value" the exact opposite of what it does. Scoped to that position,
not inherited by its subtree.
- Say plainly, in the `true` and untyped suggestions, that they narrow
the schema deliberately rather than implying an equivalent rewrite.
`true` has no portable object-form equivalent — `{}` is the very shape
this lint flags.

- Scope `non-object-root` to `inputSchema`. The pinned SDK types
`inputSchema` with `type: literal("object")` but `outputSchema` as a
bare `looseObject`, so a `{"type":"string"}` output is conforming; the
rule was claiming a requirement MCP does not make, at error severity.
- Decide `untyped-schema` from an allowlist of constraining keywords
rather than a denylist of annotations. JSON Schema ignores keywords it
does not recognize, so `{"vendorHint": true}` accepts every value and a
denylist passed it as constrained. `$defs`-only schemas now flag too.
- Walk `dependentSchemas` and draft-07 `dependencies`, with a test
pinning that the property-name-array form is not a schema position.
- Suggest `anyOf` branches for an array-form `type`, never "drop it from
`required`" — accepting `null` and permitting absence are independent
contracts, so the old suggestion silently changed the schema's meaning.
- Reject `--strict` alongside `--app-info`. That path returns NDJSON from
`runMethod` and never reaches the lint, so the flag was a no-op gate
that could never fail.
- Colour the web sidebar flag from the `--inspector-*` severity tokens,
matching the detail panel and avoiding the default yellow that failed
the a11y check.
- Add a live integration test for `rawToolSchemas`. It caught that an
`outputSchema` override on a preset returning no structured content
makes every call to that tool fail client-side validation — the
showcase config did exactly that, so the flagged tool could not be
run. Moved the bare `true` onto `get_temp`, documented the caveat, and
pinned both halves.
- Drop the double cast from the lint test fixture.

Closes#1005
A tool schema can be perfectly legal JSON Schema and still be rejected by
the client the server is meant to run against — Go's `jsonschema` emits a
bare `true` for `interface{}`, which the SDK accepts and Claude Code
refuses with an opaque "Invalid input". The Inspector passed it through
silently.
Adds `core/json/schemaLint.ts`, a portability lint over a tool's
inputSchema/outputSchema, and surfaces one shared verdict everywhere:
the CLI's `--strict` report (exit 6 on an error-severity finding), the
TUI's tool list marker + detail pane, and the web Tools sidebar flag +
detail section.
Deliberately not a JSON Schema validator: a census of 617 public servers
found zero that fail the SDK's own parse, so a conformance check would
report nothing on real servers. Each rule is instead a construct that is
legal JSON Schema and known to be refused or mishandled by a shipping
client — a bare boolean in a schema position, an array-form `type`, a
remote `$ref`, a schema with no validation keyword, a non-object root.
`test-servers/configs/unportable-schemas-http.json` exercises every rule,
via a new `rawToolSchemas` override — the Zod-built presets cannot emit
any of these shapes, which is the same reason a real server only hits
this when its schemas come from another generator.

Copilot review round 11 on #2114. The docs claimed the persisted scope
"self-heals on the next grant"; on the ordinary authorization leg it
did not.
`authenticate()` never set `pendingAuthorizationScope` — only the
step-up paths did — so `completeOAuthFlow` called
`resolvePersistedScopeAfterGrant(tokens.scope, undefined)`. When the
token response omits `scope` (RFC 6749 §5.1: omitted means the grant
matched the request), the fallback was undefined, nothing was saved,
and the stale `offline_access` stayed in storage where
`resolveEffectiveGrantedScope` keeps reporting it as granted.
`authenticate()` now records the scope it actually requested, read once
from the filtering getter so what is recorded is what went out.
Gated on the filter being active rather than applied unconditionally.
The general version is arguably more RFC-correct, but it would change
what lands in storage for every server that never touched this setting,
inside a PR whose contract is that nothing changes unless the box is
unchecked. With the grant declared, request and storage agree and there
is nothing to heal.
Three tests; the omitted-scope one fails when the recording is removed.

Copilot review round 10 on #2114 — a defect in round 8's fix, and the
precise loop that fix's extra argument was added to prevent.
`enrichChallengeWithScopes` narrows `requiredScopes` to the *missing*
subset, so a challenge requiring `offline_access tools:write` against a
stored scope that already carries `offline_access` arrives as just
`["tools:write"]`. Passing that narrowed list made the filter read the
server's explicit requirement as inherited and strip it, so
re-authorization would earn the same challenge forever.
Passes `challenge.requiredScopes` — the raw list — instead. The mixed
case is now covered, and fails against the narrowed list.
Also stops the checkbox promising more than the setting delivers: it
does not register anything for a preconfigured or CIMD client, and the
authorization server decides issuance either way. It now says it
declares the grant so the server *may* issue a refresh token.

Unrelated to #2108's diagnostics work, folded in at the maintainer's request
rather than tracked separately.
The sticky full-bleed bar cost the whole view a band of vertical space for what
is a notification about one server, and it pushed down the monitoring sidebar
that an OAuth failure now opens. Every corner is spoken for — the toast stack
owns bottom-right, the right edge is the sidebar whose toolbar an anchored card
covers, top-left is the Servers header — so it is centered instead, which is
the one placement that reads as addressed to the window rather than attached to
the wrong panel.
Deliberately WITHOUT an overlay. This is a notification, not a decision that
must be made now, and blocking the page would force a choice between reading
the requests that explain the failure and keeping the affordance — dismissing
is not free, since "Authorize again" also clears the stale OAuth state, which a
plain reconnect does not do.
Kept as the existing declarative component rather than routed through Mantine's
`notifications`: that module is mocked in App.test.tsx, so switching would have
broken the ten tests asserting on this banner's text and its action button,
including the lost-authorization-state coverage. The message now stacks above a
right-aligned action, which a ~420px card needs.

Copilot review round 8 on #2114.
The provider's `scope` getter is not the only request path. Mid-session
`insufficient_scope` recovery builds its union from *raw* storage in
`enrichChallengeWithScopes` and hands it to `mcpAuth` directly, so it
never reads that getter. An `offline_access` inherited from an earlier
grant therefore reappeared during step-up and the SDK re-added
`prompt=consent` with the setting off — the failure this option exists
to prevent, on the one path that bypassed it. The comment claiming the
getter was "the one seam both readers go through" was wrong, and is
corrected to name both.
`handleAuthChallenge` now applies the same filter, gated on the setting
so the default path is untouched. The forced-retry reuses that value,
so filtering once at the computation site covers it.
`scopeForDeclinedRefreshGrant` gains the scopes a challenge requires,
honored exactly like a configured one: stripping a scope the server is
asking for would loop — re-authorize, earn the same challenge, strip it
again.
Three regressions; the inherited-scope one fails when the filter is
reverted.

Copilot review round 6 on #2114.
The early return handed back the persisted scope unchanged, so an
`offline_access` the user had just typed into Scopes never reached the
request when storage predated the change — and storage routinely does,
since `createOAuthProvider` preserves a stored scope rather than
reseeding from current settings. The docs promised configured scopes
are honored and the form warned that `offline_access` "is still
requested"; both were false in exactly that state.
Honoring it means adding it, not merely declining to strip it.
Only the token itself is added, not the rest of the configured scope:
unioning unrelated configured tokens into the request is outside what
this setting governs and could push an otherwise-satisfied connection
into a step-up authorization.
Three tests, all verified to fail against the previous behavior.

Copilot review round 5 on #2114 — a hole in last round's fix.
When the persisted scope was `offline_access` alone,
`scopeForDeclinedRefreshGrant` returned undefined.
`OAuthManager.createOAuthProvider` reads that as "nothing stored" and
seeds storage with the configured scope, so the request-only filter
silently overwrote the value it promised to leave alone — and
re-enabling the grant could no longer restore it.
It now falls back to the configured scope, which is both the right
thing to request and inert to that branch. The previous "storage is
never rewritten" test could not see this: it ran at the provider level,
while the seeding branch lives in the manager. The new regression runs
there, and fails when the fallback is removed.
Also corrects the EMA rationale, which was wrong even though its
conclusion held. `createOAuthProviderForTransport` does build a
`BaseOAuthClientProvider` and wrap it, and `EmaTransportOAuthProvider`
forwards `clientMetadata` — so the setting is not bypassed outright.
What it cannot change is the IdP authorization leg's fixed
`openid offline_access`, which is the leg the user signs in through and
therefore the reason the control cannot affect EMA's consent behavior.
Fixed in the docs, the code comment, the UI string and the test.

Copilot review round 4 on #2114 — a real gap, not a wording one.
Declining the grant stops the SDK *adding* `offline_access`, but the
Inspector's own storage puts it back. A successful default-on
authorization persists the scope the AS granted
(`resolvePersistedScopeAfterGrant`), `offline_access` included;
`prepareForAuth` reloads it and `authenticate` hands it to the SDK as
`scope`, which sees the token in scope and appends `prompt=consent`
again. So any server that had authorized once could uncheck the box and
still hit AADSTS90094 — the users most likely to reach for the setting
were the ones it did not help.
`scopeForDeclinedRefreshGrant` filters it out of the *request* only,
applied in the provider's `scope` getter — the one seam both
`clientMetadata.scope` and `authenticate`'s `scope:` argument read
through. An `offline_access` the user configured is honored; storage is
never rewritten, so re-checking the box restores the old behavior
instead of finding the value destroyed, and scope-satisfaction checks
still see the real grant. Verified by reverting the filter: the new e2e
regression fails.
Also from that round, both previously suppressed:
The checkbox looked effective under enterprise-managed authorization,
which never builds this provider at all — it authorizes against the
enterprise IdP with a fixed `openid offline_access`
(`ema/constants.ts:16`). It now annotates itself the way the endpoint
overrides do. The existing count assertion covered two such notices and
was named for the overrides alone; it is renamed and expects three, with
a dedicated case pinning the notice to this control so the count cannot
be met by three copies elsewhere.
And "obtains no new refresh token" was another overstatement — the AS
decides issuance, and a preconfigured client is reused with whatever its
registration already permits. Replaced with what the setting actually
controls.

Review round 4 raised that the callback catch leaves `activeServerId` set: the
disconnect there emits only on a status change, and a rejected token exchange
throws inside `completeOAuthFlow` before the reconnect, so the client is still
at its initial "disconnected" and the listener that would clear it never fires.
That is accurate, and clearing it is nonetheless wrong. "Authorize again" on
the re-auth banner hands `clearServerOAuthState` the live client only when the
banner's server is the active one; releasing it here passes `null` instead and
the stale tokens are never cleared from the client holding them, which is the
one thing that recovery exists to do. Confirmed by trying it — the existing
lost-authorization-state test fails on `clearOAuthTokens` never being called.
So the retention is now asserted rather than incidental, with the reason at
both the code and the test, and the InspectorView double surfaces `activeServer`
so a later cleanup of the apparent leak fails loudly instead of quietly
breaking the recovery.

- The SSE branch selects a caller-supplied `eventSourceInit.fetch` as-is, so
it bypassed the challenge observer and a first-time legacy SSE
authorization lost the advertised URL the same way. Observing is passive,
so it is applied to that fetch too while the deliberate no-proxy-wrap rule
stays. Covered behaviorally against a 401-serving server.
- Dropped an `as unknown as typeof fetch` from the new integration test
(banned by AGENTS.md, and it erased the signature); the spy is typed as
`typeof fetch` directly. The `as MCPServerConfig` beside it was
unnecessary too.
- The integration test reused a per-pid OAuth storage file. SDK `auth()`
persists the advertised URL in its discovery state, so a rerun could
satisfy discovery from that cache and pass with the plumbing removed —
which would have quietly falsified the regression check. Fresh mkdtemp
per run, removed in teardown.

Review round 3.
Both catches report a failure without ending the attempt, and in each the
preceding rejection is an auth-recovery error — which deliberately holds the
status at "connecting" rather than moving it to "error". So the toggle spins
and the active-server lock is never released:
- the auth-recovery arm, when `checkAuthChallengeSatisfied` is what rejected
(the retrying `connect()` does reach "error", so only this half was stuck);
- the callback leg, whose `resumeAfterOAuth` carries a reconnect that can
reject the same way. Disconnect ahead of the EMA guard there, since a stuck
session is worth clearing whichever way the error classifies.
The fetch log survives a disconnect, so the Network diagnostics this issue is
about are unaffected. Both teardowns are asserted by the tests that already
cover those arms.
Also fixes a stale comment left by round 2: the arming-hooks type carries four
hooks, not three.

The challenge-driven plumbing did not reach the default CLI/TUI flow. With
no stored token in the legacy era, InspectorClient deliberately builds the
transport with no authProvider (so the SDK cannot open a browser before the
callback server is listening), which also leaves challenge interception off;
the 401 then surfaces as the SDK's headerless UnauthorizedError and the
runner calls authenticate() with no challenge in hand. So a server serving
metadata only at the advertised path still failed there — including for the
legacy showcase the README instructs.
Add a passive counterpart to the challenge interceptor: an observer fetch
that reports every 401/403 without touching control flow or the body. The
OAuthManager records the advertised URL from it and uses it in
authenticate() and its CIMD pre-registration. Latest-wins, including
clearing when a later challenge advertises none.
Also: the fixture helper dropped an explicitly supplied empty
resourceMetadataPath by truthiness, bypassing validation and silently
reverting to the well-known route.
Covered by a direct-client integration test that drives connect ->
authenticate() against the real server and asserts the advertised path was
requested and the well-known one never was; verified failing without the
fix.

Copilot review round 3 on #2114.
The unit tests asserted our own `grant_types` array and stopped there.
What actually unblocks an Entra tenant is what the SDK puts in the
authorize URL, and nothing covered that — so an SDK change that stopped
keying its augmentation off `grant_types` would leave AADSTS90094
intact with every test green.
Adds the complementary case to the existing e2e suite, against a real
AS advertising `offline_access`: with the grant declined, the authorize
URL carries neither `offline_access` nor `prompt=consent`, while the
configured scope still goes out. Verified non-vacuous by reverting the
provider conditional — it fails. The positive test alongside it now
also asserts `prompt=consent` is present, which was unasserted despite
being the literal failure in the issue.
Drops an unjustified `as unknown as ServerEntry` I added in the App
test — AGENTS.md forbids it, and it hid a real mismatch (a partial
settings object against a complete one). Typed `ServerEntry` /
`InspectorServerSettings` fixtures instead, so a field added to that
interface later is a compile error rather than a missing value at
runtime. The `constructedOAuth` helper reads through the constructor's
own parameter type and needs no cast at all now.
Scopes the two doc comments that still claimed the flag removes every
`offline_access` — `StoredMCPServer.oauth` and `OAuthProviderConfig`,
both contradicting the caveat already stated elsewhere.

Review round 2.
The flag in the resume catch sat above the EMA guard, so an unconfigured
enterprise client was marked a failed connect — which contradicts the round-1
argument for leaving EMA unflagged in the two connect-path arms. Moved below
the guard so all three agree, and still above the classification fan-out so
every arm that is a real failure carries it.
Adds the two tests the round flagged as missing: an OAuth storage `load()`
that rejects (spied on `RemoteOAuthStorage.prototype`, so every other test
keeps the real storage), and a *rejecting* challenge check — the distinct
control-flow decision introduced last round, where a broken check is surfaced
rather than treated as an unsatisfied challenge and used as grounds to navigate
the page away. That one asserts no resume snapshot was written, which is what
`prepareOAuthRedirect` would have done first.

`isOriginRelativePath` compared the resolved href against the literal, which
`URL` preserves a query and fragment in — so `/doc?version=1` and `/doc#section`
passed. Express matches on the path alone (and treats `?` as a pattern
character), and a fragment never reaches the server, so the advertised URL
could not resolve to the registered route. Reject both, with cases added to
the table-driven test.

Copilot review round 2 on #2114. The setting was described as
guaranteeing "no offline_access, no forced prompt", which is not what
the SDK does.
`startAuthorization` appends `prompt=consent` for any `offline_access`
in the effective scope and never consults `grant_types`, and
`determineScope` skips its augmentation when the scope already carries
it. So the prompt still goes out when the user configured
`offline_access` in Scopes, or left Scopes blank and the resource
advertises it in `scopes_supported`. The flag removes the SDK's
*automatic* augmentation and nothing more; the docs, the help text and
the type say that now.
The form also flags the case a user can act on: opted out while
`offline_access` is still listed in Scopes. Whole-token match, so
`offline_access_extra` does not trip it.
Corrects the Clear stored OAuth state claim too. It clears the local
tokens and client information — it is not a revocation and cannot
reach the AS. A dynamically registered client re-registers on the next
connect (the new registration declaring only `authorization_code`); a
preconfigured `oauth.clientId` is reused unchanged.
Adds the two missing seam tests, both confirmed to fail without the
code they cover: App's connect wiring (deleting the spread fails two of
the three) and an /api/servers POST followed by a read-back, since a
200 alone never proved the opt-out persisted.

AGENTS.md requires review-relevant rules to be mirrored into
.github/copilot-instructions.md in the same PR, and that file already
carries a Dependency placement section. Add the distilled form of the
new overrides guidance: use an `overrides` entry rather than
`npm audit fix` when the advisory range has no upward escape inside the
parent's declared range, gate such a pin on the build rather than the
audit, expect the lockfile diff to touch only that package, and say when
the pin can be dropped.

`npm audit` (dev included) reported a low-severity advisory against
`esbuild` in three of the four client installs. It is not in the
production tree — `npm audit --omit=dev` has been clean everywhere since
2058 — but a permanently non-clean audit trains people to skim the
channel, which is the same argument 2058 made.
`tsup@8.5.1` declares `esbuild: ^0.27.0`, and the advisory covers
0.27.3 - 0.28.0 with 0.27.7 the last 0.27.x, so there is no upward
escape inside tsup's declared range. `npm audit fix` "resolves" it by
silently downgrading to 0.27.2 across three installs — the trap hit and
reverted during 2058. An `overrides` entry forces the copy above the
range instead.
- Add `"overrides": { "esbuild": "^0.28.2" }` to clients/{web,cli,tui}.
That also covers the tui's `tsx` copy (0.28.0), so no separate update
is needed.
- Re-resolve each lockfile. Every changed entry is an esbuild one: the
nested `tsup/node_modules/esbuild` and `tsx/node_modules/esbuild`
copies collapse into the single deduped 0.28.2, and no other package
moves.
- Document the pin in AGENTS.md, including when to drop it.
The real gate here is the build, not the audit: this puts tsup on an
esbuild major it does not declare. `npm run build` succeeds for all
three clients, and `npm run ci` passes.

Review round 1.
The satisfied-challenge arm re-connects from inside the outer `catch` with two
unguarded awaits, so a rejection there escaped `onToggleConnection` entirely —
an unhandled rejection with no toast, no red border and no sidebar, which is
this issue's failure mode in its most invisible form. Surface it as the failed
connect attempt it is. A throw from `checkAuthChallengeSatisfied` lands there
too rather than falling through to the redirect: it is not the same as the
challenge being unsatisfied, and navigating the page away on the strength of an
error would bury it.
The provider-error and OAuth-storage-load arms return before a client is
rebuilt, so they raise the red border and deliberately not the sidebar — the
diagnostic is the provider's `error` param (already in the banner) or a local
storage failure, neither of which is in the network log. Said so at both sites
and on the test, which asserts the flag and nothing more on purpose.
Also drops the three `as unknown as` casts on the test-only arming hooks for a
single intersection cast that keeps the module's real shape checked, and turns
the armed connect rejection into a FIFO queue so a test can arm the two
consecutive connects the recovery retry makes.

Two findings from review:
- `ensureCimdClientRegistration` ran protected-resource discovery on the
global fetch while its AS-metadata leg used the configured one. On web
that is `createRemoteFetch`, which proxies through the backend to sidestep
CORS — so the discovery this PR routes to a challenge-advertised URL would
fail in the browser, be swallowed by the catch, and leave CIMD probing the
wrong authorization server. Forward `params.fetchFn`, and assert in the
test that nothing reaches the global.
- `oauth.resourceMetadataPath` accepted `//other-host/doc`. Resolved against
the request base that re-points the origin in the advertised
`resource_metadata` while Express still registers the route locally, so the
server would advertise a document it does not serve. `/\\host` does the
same, since the URL parser folds a backslash into a slash for special
schemes — a leading-slash check misses both. Validate origin-relativity
with a shared predicate, used by the JSON-config validator and again at
server setup for a programmatically built ServerConfig.

Copilot review on #2114. The setting was described as taking effect
"immediately", which is wrong twice over.
`applyLiveServerSettings` treats OAuth as connection-time-only, so a
connected client keeps the metadata it was built with — deliberately,
and identically to every other field in that section (client id,
secret, scopes, authorizationParams, endpoint overrides). Not wiring
this one field live; saying "next connect" instead, in the docs, the
checkbox description, and the type.
And two pieces of state outlive the setting: the registration already
held at the authorization server still lists the grant, and a refresh
token issued earlier stays usable, because the SDK's
`refreshAuthorization()` posts the stored token without consulting
`grant_types`. So the stated cost is not guaranteed until stored OAuth
state is cleared. Documented, rather than revoking credentials as a
side effect of a checkbox — Clear stored OAuth state already does that
explicitly.
Also adds the manager->provider seam test the other bridges have:
without it, deleting `requestRefreshToken:` from `createOAuthProvider`
would leave the feature dead with every other test green.

The failure column was gated on the `"error"` connection status, which an
OAuth failure never reaches: the parent drives the auth legs itself and tears
the client down on failure, so the session settles at `"disconnected"`. The
sidebar therefore stayed shut on exactly the failure the Network tab exists to
explain — the case #2048 was closed on.
Gate it on `erroredServerId` instead, the parent's canonical "this server's
last connect attempt failed" flag, and set that flag on every OAuth
connect-attempt failure: the pre-redirect discovery/DCR leg, the callback
leg's token exchange, an OAuth-storage load failure, and a provider that
redirects back with an error instead of a code.
Nothing else was needed to make the requests reachable. `auth` fetches are
already tracked into the Network store, which does not clear on disconnect and
is restored from the session on the callback leg, so discovery, DCR and the
token exchange are all present. Tab selection stays content-gated rather than
hard-coded, so Network leads because it is the one that captured something.

The Inspector always declared `refresh_token` in its OAuth client
metadata. The SDK's `determineScope()` then appends `offline_access`
whenever the authorization server advertises it and the client declares
that grant, and `startAuthorization()` appends `prompt=consent` whenever
`offline_access` is in scope. Against Microsoft Entra ID that forced
consent prompt routes a non-admin user into the admin-consent workflow
and fails with AADSTS90094 — even after a tenant admin has consented.
Adds a per-server "Request refresh token" setting (default on) that
drops the grant from the client metadata, breaking that chain at its
source. Persisted as `oauth.requestRefreshToken` and written only when
off, so entries that never touch it keep a byte-stable round-trip. Web
edits it in Server Settings → Authorization; the CLI and TUI pick it up
from the same per-server settings via `buildRunnerClientAuthOptions`.

An RFC 9728 `WWW-Authenticate: Bearer resource_metadata="…"` challenge was
parsed and then dropped by the normalized `AuthChallenge`, so every
challenge-driven `mcpAuth()` call ran discovery without it and probed
locations derived from the MCP server URL instead. OAuth failed outright
against any server whose metadata document lives off the well-known path.
The SDK handles this correctly inside its own transports, but the Inspector
never reaches that path — it intercepts the 401 and drives `auth()` itself
to capture the authorization URL and run the step-up scope union.
Carry the advertised URL on `AuthChallenge` as a string (it crosses the web
client's remote-backend boundary as JSON), convert it at the OAuth boundary,
and pass it to the standard challenge leg, the forced step-up leg, and CIMD
pre-registration — which runs before `auth()` and did its own discovery. A
malformed value is ignored rather than surfaced, matching the SDK's parser.
The callback leg needs nothing: SDK `auth()` persists the URL in its
discovery state.
Adds an `oauth.resourceMetadataPath` test-server mode that moves the
document off the well-known path entirely, so the integration test proves
discovery genuinely fails without the fix.
Closes#2071

The web client and the TUI both read `savedSettings.metadata` and pass it
as `InspectorClientOptions.defaultMetadata`. The CLI never did, and
`InspectorClient` only reads the option rather than falling back to
`serverSettings.metadata` — so a per-server `metadata` entry was silently
inert for `--cli` runs.
Pass it beside the existing `roots:`, guarded on a non-empty map the same
way web and the TUI guard theirs, so `{}` still means "no defaults".
Precedence is unchanged: call-time keys override defaults in `mergeMeta`,
so `--metadata` stays per-invocation and wins on a key collision.
Covered by three catalog-driven tests asserting against the test server's
recorded wire requests. `createTestConfig` is retyped `StoredMCPServer` —
the accurate on-disk shape — since a fixture that cannot express the
per-server keys cannot cover the settings that reach the client.
