b0b252a5c0 fix: address Copilot review round 41 — const does not demand a property, required-only branches
- `const` constrains a property that is PRESENT; it neither requires the
  property nor acts as a default. It is now supplied automatically only where
  the schema also requires the field — in `collectSchemaDefaults`,
  `applySchemaConstants` and the TUI's initial values alike — so an optional
  `dryRun: { const: true }` no longer turns a valid `{}` call into one that
  asks the server to do something. A value that IS present is still corrected
  to the constant, whatever supplied it, and the field stays read-only.
- Offerability is judged on the base+member merge rather than the raw member,
  so `anyOf: [{ required: ["email"] }, { required: ["phone"] }]` over
  root-declared properties is offered. It was declined, which left the gate
  checking the base alone and accepting `{}` — which that schema rejects.
- The TUI's branch sections keep the schema's own `required` for the seeding
  decision while still rendering every branch field non-required, which is what
  keeps a static form submittable.

48651956e5 fix: address Copilot review round 39 — identify branches by their schemas, cover the deep-link path
- branchesKey is built from the resolved alternatives themselves, not from
  labels and field names: two branches can share both while pinning different
  discriminators or typing a field differently, and a reorder of those went
  unnoticed — the form then displayed one branch and submitted another.
- InspectorView gains a deep-link test with root-union appArgs: they name the
  second branch, and the assertions pin the picker, the read-only
  discriminator, THAT branch's default (not the first branch's), and the
  absence of the other branch's field. The old shallow spread fails it.

85b030cbde fix: address Copilot review round 37 — stale constants, inherited answers, prefixed labels
- The seeding effect re-applies constants as well as filling absences: an
  in-place schema change can move a `const` the user cannot edit, and the
  read-only field then displayed the new value while `values` still held the
  old one — which is what would be submitted. Ordinary defaults are still only
  ever added, so an edited field keeps what the user put there.
- hasMissingIn checks own-property presence: a required argument legally named
  `constructor` resolved to the inherited one and read as supplied, enabling
  a submit the schema rejects.
- The TUI keeps the declared name as a branch field's fallback title. The
  prefix is an internal field NAME, and buildFields labels from its map key —
  so the showcase displayed `__b0__address` where the schema says
  `address`.

f78b541ce1 fix: address Copilot review round 36 — re-derive the branch when the union changes underneath
`branchIndex` is a position, and a tool refreshed in place keeps its
`resetKey` — so a union reordered or rewritten with the same number of
branches left the index pointing at a different shape than the one the values
describe: the picker showed SMS while Execute submitted the email arguments.
The selection is now re-derived from the values whenever the alternatives
themselves change, keyed by their labels and declared fields.

139563f720 fix: address Copilot review round 35 — reseed on an in-place schema change, label every primitive const
- The seeding effect is keyed by the fixed values themselves as well as the
  entity and branch. A tool refreshed in place keeps its `resetKey` and its
  branch while its schema changes underneath, so a newly pinned field was
  rendered read-only and never seeded — leaving a required one permanently
  unsubmittable. The schema object's identity says nothing (callers rebuild it
  every render), which is why the key is derived from what has to be seeded.
- branchLabel stringifies every primitive constant. `hasDiscriminator`
  accepts distinct booleans and nulls, so a `true`/`false` union was
  discriminated perfectly well and still labelled "Option 1"/"Option 2".

ffa08d76f5 fix: address Copilot review round 33 — keep a cleared field cleared across a branch switch
The carry filter dropped a name whose value was `undefined`, but clearing a
number or JSON field leaves exactly that: the name present with no value, which
is the user's answer rather than an absence. The incoming branch's defaults
then put the field's default back and undid the clear. Own-property presence
alone is now the test.

67e7a4ca1a fix: address Copilot review round 30 — seed a read-only const for callers that do not
Rendering every `const` read-only assumed the caller had already seeded it,
which SchemaForm never did itself: `InlineElicitationRequest` passes its
values straight through and gates submit on hasMissingRequiredFields, so a
required `const` — a root union's discriminator among them — was displayed
and never supplied, leaving Submit disabled with no way to fix it.

The form now reports the fixed values upward once per entity, in an effect (the
parent's `onChange` cannot be called during our render), adding only names
absent from `values` — so a caller that already seeds sees no call at all and
the report cannot loop.

d49798c91c fix(web): key enlarge carets by Map, and count maxLength in code points
Two more from review, both about field data the schema controls.

The caret record was a bare object keyed by field name, and field names
come from a server's schema. A field legitimately named `constructor` or
`toString` read back an inherited function rather than undefined, so the
documented end-of-value fallback never fired and that value reached
setSelectionRange. Use a Map, which has no such keys.

JSON Schema counts maxLength in Unicode code points; String.length counts
UTF-16 code units. A field holding one emoji measured 2, so a maxLength:2
field with room for another character was treated as full and refused its
newline. Count code points. The maxLength handed to the DOM input still
carries the HTML attribute's own UTF-16 counting; that predates this and
is left alone.

1d3b973742 fix(web): read the enlarge split from the control, and keep the caret
Two faults in the Enter path, both found in review.

The split read `values[fieldName] as string`, a cast over a
Record<string, unknown> fed by whatever a server's schema declares. A
string field holding a non-string default renders as text and then threw
on `.slice`, so one keystroke crashed the panel. Read the control's own
value instead: always a string, and the exact string the selection
offsets index into.

The caret was recorded only when the newline fit, so pressing Enter mid
value in a field at its maxLength enlarged without one and threw the
caret to the end — a second surprise on top of the newline that did not
arrive. Record it on both paths, `start + 1` after an insertion and
`start` otherwise.

c9054ec058 fix(web): reject the IME keydown that only reports keyCode 229
isComposing covers browsers that fire compositionend after the
committing keydown. WebKit is reported to fire it before, which leaves
isComposing already false and the CJK user back to a stray newline on
every committed word.

Also reject keyCode 229, the pre-isComposing sentinel for a keydown the
IME consumed, which such an event still carries. Deprecated, and kept
anyway: nothing non-deprecated distinguishes that event, and it cannot
swallow a real Enter, which reports 13 — tested both ways so the
sentinel is provably not eating ordinary keystrokes.

The ordering claim is second-hand; the guard is taken on its own merits,
since its downside is bounded at zero and it covers any browser whose
composition events land too late rather than one vendor.

7ec0be0d12 refactor(web): lift the enlarge key handler out of JSX

4f19ee3238 fix(web): insert the enlarge newline at the caret, not at the end
Enter appended its newline to the end of the value regardless of where
the caret was, so pressing it in the middle of `abc|def` produced
`abcdef` with a trailing blank line rather than splitting the text, and
a selected range was kept rather than replaced. That is a rewritten
value, not just a misplaced caret, and no editor behaves that way.

Split at the field's own selection and replace any selected range, then
mount the text area with the caret just after the inserted newline —
EnlargedStringField takes an explicit caretAt for this. Pointer
activation passes none and keeps falling back to end-of-value, since a
click carries no meaningful position. The maxLength check now prices the
resulting value, so replacing a selection can free the room the newline
needs.

The two maxLength tests were asserting against a stub onChange, which
froze the value and made "it did not change" pass whatever the component
did. They now run on a seeded stateful harness, with a no-maxLength
control so the constraint is shown doing the work.

f02a6161e4 fix(web): don't enlarge on the Enter that commits an IME composition
Enter is also how a Japanese, Chinese or Korean input method commits the
candidate being composed. That keystroke means "accept this word", not
"new line", so the shortcut fired on every word such a user finished —
enlarging the field and inserting a stray newline each time.

Guard on event.nativeEvent.isComposing. The test pairs the composing case
with a negative control dispatching the same event with the flag off, so
a test that stopped reaching the handler cannot pass for the wrong reason.

  anything else, so reporting the seeded value as missing made such a branch
  permanently uncallable.
- A nested SchemaForm is reset by the branch-aware key too. Two outer

  for the other one while the newly seeded values described another shape.

09914772ea fix: address Copilot review round 15 — unevaluable const siblings, $ref fields, per-branch draft keys
- rootUnion: a merged declaration pairing a `const` with an assertion this

  conjunction safe is the requirement, not disproving it — `minimum: 10`
  beside `const: 1` is as unsatisfiable as a type mismatch.
- declaresAnyFields counts a `$ref`: its shape is unknown rather than empty,
  so `anyOf: [{ $ref }, { $ref }]` no longer reports an App tool as
  input-free and auto-invokes it with `{}`.
- SchemaForm keys its draft-holding fields by the active branch as well, so a
  half-typed `-` or an unparsed JSON draft cannot survive a switch into a
  same-named field of the incoming branch — with both parent values
  `undefined`, nothing else tells the field the entity changed.

85b8e4601c fix: address Copilot review rounds 7 and 8
- rootUnion: a `oneOf` demands that EXACTLY one alternative match, which
  flattening cannot preserve, so it is offered only when a discriminator makes
  the alternatives mutually exclusive; `anyOf` makes no such claim and is
  unaffected. An empty `additionalProperties` schema is the equivalent of
  `true` and no longer declines a union.
- selectBranchIndex: falls back to the branch whose own required fields the
  values supply, so an undiscriminated union's values open the picker on the
  shape they describe rather than on the first branch.
- admitsNull: honors a sibling `nullable: true` beside `const: null`.
- SchemaForm: a value is carried only where the incoming branch leaves the
  root's declaration as it found it; anything it declares itself is reset,
  since it may type the name differently from where the value was typed.
  `hasOwn`/`fromEntries` throughout, so `constructor` is not read as a
  supplied value and `__proto__` is not dropped into the prototype setter.
- TUI: the same prototype-safe construction on the way out of the form, and
  the chosen branch's `required` list is checked at submit — rendering a
  branch's fields optional makes the FORM satisfiable, not the call, so the
  missing names are reported rather than a known-invalid call being sent.

c15e30414f fix: address Copilot review round 6 — additionalProperties, annotations, prototype-safe records
- rootUnion: decline a union that adds fields under a restrictive root
  `additionalProperties`. The keyword constrains what its SIBLING
  `properties` does not name, so the original schema admits none of the
  branch fields; flattening moves them beside the keyword, where they read as
  allowed and the form would submit what the schema forbids.
- `default` joins the annotation set: it constrains nothing, so two
  declarations suggesting different initial values no longer conflict.
- Property records are read with `Object.hasOwn` and built with
  `fromEntries`/`defineProperty`. `properties` is a JSON record, so
  `constructor` is a legal argument name that `in` reported as a collision
  the root never made, and `__proto__` is one that assignment would drop
  into the legacy prototype setter instead of keeping as a field.
- SchemaForm: a value survives a branch switch unless BOTH branches declare
  the name. A root argument the outgoing branch merely specialized is still a
  root argument in a branch that inherits it, so dropping it erased a valid
  value.

7e4af5ed34 fix: address Copilot review round 4 — allOf faithfulness, const null, branch-aware seeding
- rootUnion: an `allOf` member is foldable only when it states nothing beyond
  what the merge applies (`type`/`properties`/`required` plus annotations),
  so a nested `anyOf`, a `not`, or an `additionalProperties` can no longer
  be erased along with the keyword; members are checked against the
  ACCUMULATED merge, so two of them contradicting each other is caught even
  when neither contradicts the root.
- admitsNull: `const: null` admits null, so a required field pinned to it is
  no longer seeded with the one value it accepts and then reported missing.
- collectSchemaDefaults takes the values a caller is about to overlay, and
  seeds the branch THEY identify — the App deep link passes its `appArgs`, so
  branch 0's defaults can no longer sit invisibly under branch 1's arguments.
- The branch inference moves into core as `selectBranchIndex`, shared by the
  seeding and the form's picker so the two cannot disagree.

1a271e4931 fix: address Copilot review round 3 — conjunctive keywords, unflattenable allOf, branch inference
- rootUnion: a branch restating a constraint the root states differently is
  declined (keywords at one level are conjunctive and no intersection is
  computed here), while annotations may disagree freely. An `allOf` with a
  member it cannot fold in — JSON Schema's boolean form, or a $ref whose
  constraints are unknown rather than absent — is left intact instead of
  merged-and-stripped, which would turn an unsatisfiable schema into a
  fillable form.
- rootUnion: `declaresAnyFields` counts the raw composition members, so
  `hasInputFields` reports fields for a union the resolver declines and an
  App tool is never auto-invoked with empty arguments.
- SchemaForm: the picker opens on the branch the supplied values identify
  (an App deep link overlays its args, so they can name another branch), and
  a branch switch no longer carries a value the outgoing branch declared —
  the branches may type the same name differently.
- TUI: a base property some branch redeclares is offered in EVERY branch's
  section under that branch's inherited or specialized declaration, so a
  branch that does not redeclare it can still supply a required root
  argument.

4c338a37e9 fix(web): take the enlarge button out of the tab order
Every string field in a tool or elicitation form carries an enlarge
button in its right section, so tabbing through a form stopped on one
between each pair of fields. Give it tabIndex={-1}, as #1487 did for the
clear button.

That button was deliberately left in the tab order by #2042, on the
grounds that clearing has a keyboard equivalent and enlarging has none.
So give it one: Enter on the focused single-line field enlarges it and
enters the newline. Nothing was listening for that key there — no
consumer renders SchemaForm inside a <form> — and it is the key a user
presses trying to type the newline the input swallows, which is the
failure #2042 exists to fix.

Enter enters the newline rather than only reshaping the field, since
consuming the keystroke leaves the next word running on from the last. A
field already at its maxLength is enlarged without one. Shift+Enter
enlarges too; the Ctrl/Cmd/Alt chords are left free for a consumer to
bind to running the tool. Clicking the button still only enlarges.

- rootUnion: decline a schema carrying BOTH oneOf and anyOf rather than
  reading one and silently dropping the other's constraints.
- SchemaForm: handle `const` before every type dispatch and for every
  constant type, so a numeric/boolean constant, or a schema carrying both
  `const` and `enum`, can no longer offer a forbidden value.
- collectSchemaDefaults / TUI initialValue: `const` outranks `default`,
  which is an annotation a schema may set to something its const rejects.
- convertToolParameters: resolve from the first branch's merged schema, so a
  branch's specialization of a root-declared property is what types the arg.
- TUI: ink-form keys values by field name across the whole form, so two
  branches' `kind` were one field and the later section's initial value
  decided what the earlier submitted. Branch fields now render under prefixed
  names behind a Variant select, and decodeFormValues translates back on
  submit, dropping every branch but the chosen one.

5933162dd0 fix: render tool schemas with root-level anyOf/oneOf composition
A tool's `inputSchema` may carry composition keywords at its root — the
2026-07-28 revision makes this explicit — but both form builders enumerate
the root's `properties` and nothing else. A schema keeping its fields on
`allOf`/`oneOf`/`anyOf` branches therefore rendered no controls at all: no
branch picker, no fields, not even the raw-JSON fallback a union-typed
*property* falls back to, so the tool could only be called with empty
arguments.

Adds `core/json/rootUnion.ts`, one flattening shared by all three clients so
they cannot drift on which schemas they can render:

- `allOf` is merged unconditionally (conjunctive — there is no choice to
  present), a root `oneOf`/`anyOf` is returned as branches.
- Web `SchemaForm` renders a Variant picker above the fields and prunes the
  outgoing branch's values on a switch, since they are no longer visible and
  would describe a shape the call is not making.
- TUI `schemaToForm` gives each branch its own section with optional fields —
  ink-form is static, and only one alternative applies to a call.
- `convertToolParameters` looks through the branches, so a CLI `--tool-arg`
  is typed by the schema that declares it rather than sent as a string.

Required-field gating asks whether *any* branch is satisfied, which is
selection-independent and never blocks arguments the schema accepts. A
`const` is seeded like a `default` and rendered read-only: it admits exactly
one value, so anything else the user could type produces a rejected call.

Adds a `root-union-schemas-http.json` showcase server.

Closes #2123

68c4abf37a fix: count severities correctly, gate remote-ref on $id, order --strict checks
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.

2cb23a8b21 fix: map the new exit code, keep add runnable, distinguish severity by shape
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.

c389565783 fix: address Copilot review on the schema portability lint
- 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.

2f9e0901c1 feat: flag unportable tool schemas in all three clients
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.

fef8f5ca5a fix(oauth): pass the raw challenge scopes to the step-up scope filter
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.

d6250d6b05 fix(web): make the re-auth banner a centered popup, not a full-width top bar
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.

d29ff8b9b5 refactor(web): shorten the refresh-token checkbox description
The description had grown into a paragraph that dominated the
Authorization section, and it named a specific vendor's error code
(AADSTS90094) in a control that is not vendor-specific.

Three lines now: what the grant does, when to turn it off, when it
takes effect. The Entra specifics, the automatic-scope nuance and the
does-not-revoke caveats stay in docs/mcp-server-configuration.md, which
is where someone goes for the detail. The inline offline_access warning
and the EMA note are unchanged.

87fe7b27ba refactor(web): extract the refresh-token change handler
Copilot review round 7 on #2114 (suppressed comment). AGENTS.md
forbids inline handler logic; the new checkbox had it.

The eight OAuth controls beside it are inline in the same shape, so
consistency was an argument for leaving it. Complying anyway: this repo
holds new code to its gates even where neighbors predate them, the same
way the coverage floor works. Extracting the siblings would be an
unrelated refactor in a bug-fix PR.

1bbdef03eb fix(oauth): keep the scope filter from overwriting persisted storage
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.

89dedd8dea fix(oauth): drop an inherited offline_access when the grant is declined
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.

fca3f1ce67 fix(oauth): stop claiming the opt-out removes every offline_access
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.

f6fca59624 docs(oauth): scope what the refresh-token opt-out actually changes
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.

e2fb78d999 feat(oauth): make the refresh_token grant opt-out per server
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`.

d47071d535 fix(web): reset a tool form by row identity, not by tool name

ToolsScreen already disambiguates those rows with a key of its own, but the

ToolDetailPanel now takes an optional `resetKey`, defaulting to the name for
callers whose list cannot repeat one, and ToolsScreen passes the row key.

5340283fb4 fix(web): let tool string arguments be typed as multiline (#2042)
A string argument renders as a single-line `<input>`, which swallows Enter —
so a value containing newlines could not be typed at all.

Each string field now carries an enlarge button (ImEnlarge2) to the left of its
clear button. Clicking it swaps the input for an autosizing text area that keeps
the field's value, label, and length constraints. It is deliberately one-way:
shrinking back would have to either discard newlines the user typed or keep a
value the field can no longer show, and both are worse than staying enlarged.

Enlarging is per-field and resets with `resetKey`, so it cannot carry across to
another tool's same-named field.

129a435fd4 docs: say "safe integer" for progressToken, matching what the code enforces
The copy said `progressToken` may be "an integer" while the implementation
validates with `ProgressTokenSchema` — zod's `.int()`, which rejects anything
past `Number.MAX_SAFE_INTEGER`. This repo's own tests assert that
`MAX_SAFE_INTEGER + 1` is dropped, so the documentation was promising a value
the client discards.

Corrected in all three places, so the code comment, the docs callout and the UI
hint agree: `dropInvalidReservedMeta`'s doc block (which review did not flag),
the `metadata` reserved-keys callout, and the Request Metadata hint.

167b9b4dab fix: validate every reserved _meta member against the SDK's own schema
`progressToken` was not the only reserved key. The pinned SDK's
`RequestMetaSchema` also constrains `io.modelcontextprotocol/related-task` to
`{ taskId: string }`, and a conforming server rejects the *whole request* over
one bad reserved member rather than ignoring that key. Before #1910 every value
was a string, so only `progressToken` could be wrong; the widening made all of
them reachable.

Replace both hand-rolled checks with the SDK's schemas — `RequestMetaSchema`
for the payload, `ProgressTokenSchema` for the single value. The schema is
loose, so unknown keys pass through untouched, and zod reports the offending
top-level key as `issue.path[0]`, so only that member is dropped and its
siblings survive. A member the SDK constrains in a later release is then
covered without anyone remembering to add it — which is the drift that produced
the `isInteger`/`isSafeInteger` bug one round ago.

`name` was hard-coded, and react-ace uses it as the editor container's DOM id,
so two instances emitted duplicate ids. Derived from the per-instance id, and
deliberately distinct from the id given to the textarea — that one is what the
wrapper's `<label for>` targets, so reusing it would just move the collision.

The docs table, the docs prose and the form hint all claimed "any JSON" without
qualification, presenting a configuration as valid that the client then drops.
All three now name the reserved keys and say what happens to a bad one.

ed799a0c0b feat(web): use the Ace editor for the request-metadata JSON
A textarea is a poor place to hand-write a nested `_meta` payload. Ace closes a
brace when you open one, folds nested objects, and — through its JSON worker —
marks the offending line in the gutter instead of reporting one message for the
whole document.

Three things the swap turned up:

- Ace fires *two* change events for a replace (a remove, then an insert), so
  select-all-and-retype briefly leaves an empty document. Acting on the first
  emitted `{}` and wiped the user's saved metadata the instant they selected
  it. `handleChange` now coalesces the pair in a microtask, and the component
  tracks what it last emitted so the parent echoing that value back is not
  mistaken for an external reset.

- Ace's own `github` themes fail WCAG AA on the gutter — `#AAA` on `#e8e8e8` is
  1.89:1, and the dark theme is 4.13:1. Folding needs the gutter, so the colors
  are overridden with palette tokens (5.82:1 and 4.88:1) rather than hiding it.

- `textInputAriaLabel` alone never reaches the DOM: Ace composes the label as
  "<label>, Cursor at row N" and only recomputes it when the cursor moves, so
  it is forced once on load. Until then the control's only accessible name is a
  position readout.

Testing is split because Ace's input path does not work under happy-dom at all
— `userEvent.type` reaches the textarea and produces no edit, so a test written
that way asserts nothing. Unit tests drive the editor instance through a shared
`src/test/aceEditor.ts` helper; the real keyboard behaviour (`{` then Enter
giving `{\n  \n}`) is asserted by Storybook play functions in Chromium.

`react-ace`/`ace-builds` are declared in `clients/web` rather than the root, per
the rule for a dependency that renders React components.

b33532c024 feat: allow complex JSON values in request _meta
Closes #1910

`_meta` was typed `Record<string, string>` end to end in the Inspector —
on disk as a `{ key, value }[]` pair array, in the Server Settings form as
key/value rows, and in every request verb's per-call metadata parameter.
Nothing in the MCP spec restricts a `_meta` value to a string, and the SDK
models the field as a `z.looseObject`, so the restriction was ours alone.

Widen the whole path to `RequestMetadata` (`Record<string, JsonValue>`):

- Per-server default metadata is a JSON **object** on disk and in memory.
  The pre-#1910 pair array is still read (`normalizeStoredMetadata`) so an
  existing `mcp.json` keeps working; it is never written back, so a save
  migrates the entry.
- The Server Settings → Request Metadata section is a JSON editor
  (`JsonObjectInput`) instead of key/value rows — rows cannot express an
  object value. It keeps the typed text as the display source and emits
  only parsed JSON, the same draft split `SchemaJsonField` uses, so the box
  stays typeable; invalid text is flagged inline and not applied.
- The CLI stops flattening `--metadata` / `--tool-metadata` through
  `metaValueToString`. Those values were already JSON-parsed, so
  `trace={"id":"abc"}` used to reach the wire as the *string* `{"id":"abc"}`
  and now reaches it as an object.
- `servers/show` redaction replaces a sensitive key's whole value rather
  than a string, so a structured value cannot leak through its members.
- `progressTokenOf` narrows the reserved `progressToken` key back to
  `string | number` before it reaches the SDK; any other JSON still travels
  inside `_meta` but wires up no progress callback.

15e9260484 fix(auth): make the durability guard provenance-aware, and harden the claim
Round 20, and almost all of it is fallout from round 19's two changes. Both
were right in direction and wrong in the detail, in the same way: each solved
its case by treating a broad thing as a proxy for a narrow one.

**The durability guard wrote newly entered secrets to disk in plaintext.**
Preserving legacy plaintext for a session-scoped store is correct — stripping
it moves the only durable copy into RAM. Using *the whole submitted entry* as
the proxy for "legacy" was not: it turned
`MCP_INSPECTOR_SECRET_STORE=memory` into "write every new secret to
`mcp.json` in the clear", while the footer for that very store says secrets
are written nowhere. A security regression introduced by a data-loss fix, and
the same overshoot in `client.json`.

Provenance decides now. A secret field is kept on disk only when it was
already there, unchanged, in the file being overwritten; a newly entered or
changed value is stripped and lives in the session store, which is exactly
what the footer promises. Where provenance cannot be established — an
unparseable prior file — the value is treated as new, because writing a
secret to disk on a guess is the failure that matters.

**The atomic claim was not as safe as its comments said.** Four ways:

- A crash between the claim and the copy left only
  `secrets.json.migrating-<pid>`. The next run checked the canonical path,
  found nothing, selected the keychain, and every stored credential vanished
  with no warning. Orphans are now adopted at startup.
- Restoring used `rename`, which on POSIX **replaces** its destination — so
  the restore path could overwrite a `secrets.json` a concurrent writer had
  recreated, destroying the later successful write that claiming exists to
  protect. The comment beside it asserted the opposite. `link` + `unlink` is
  the no-clobber primitive this needed.
- Every claim failure was read as a lost race. `EACCES`/`EROFS` leave the
  file exactly where it is, and returning quietly selected the keychain while
  file-backed secrets sat there invisible. Only `ENOENT` is benign now.
- A failed cleanup left a plaintext-capable snapshot on disk with a silent
  catch, while the app reported the keychain as the only store. It names the
  path now.

**A third secret-entry surface had no disclosure at all.** `ServerConfigModal`
takes stdio `env` values, which are extracted into the store exactly as
Server Settings' are — and the footer's own doc comment claimed there were
only two such dialogs. It has the footer now, and every server write that can
carry a secret (config submit, both import flows) refreshes the descriptor,
not just the settings save.
