web: pin Connection Info modal header while body scrolls (#1754) (#1755)
Same fix as #1698, applied to the Connection Info modal, which had the same
pattern: a custom header Group (title + close) inside a Stack in the modal body,
using the default `<Modal>` with no `scrollAreaComponent`. With a long server
`instructions` section (e.g. the everything server) the details overflow the
viewport and the whole modal scrolled, taking the header out of view.

Switch to the compound `Modal.Root`/`Content`/`Header`/`Body` API, move the
header into `Modal.Header` (sticky by design) and set
`scrollAreaComponent={ScrollArea.Autosize}` so only the body scrolls. The
fade-down transition is supplied app-wide by `ThemeModalRoot` (added in #1753),
so no `transitionProps` literal is needed here.

Closes #1754

web: pin Server/Client Settings modal header while body scrolls (#1753)
* web: pin Server/Client Settings modal header while body scrolls (#1698)

Expanding enough accordion sections grew the Server Settings modal past the
viewport, so the whole modal scrolled and carried the header (title + close)
out of view. The header was a custom Group inside the modal body, and the modal
used no `scrollAreaComponent`, so overflow was not confined to the body.

Switch both the Server Settings and Client Settings modals from the default
`<Modal>` (which always wraps children in `Modal.Body`) to the compound
`Modal.Root`/`Modal.Content`/`Modal.Header`/`Modal.Body` API, moving the
toggle/title/close row into `Modal.Header` (sticky by design) and setting
`scrollAreaComponent={ScrollArea.Autosize}` so only the body scrolls.
`Modal.Root` keeps the close-on-escape / close-on-click-outside / focus-trap /
scroll-lock / portal defaults; `transitionProps` restores the fade-down
animation the `<Modal>` wrapper otherwise supplies. Client Settings does not yet
have enough content to scroll but is kept consistent per the issue.

Closes #1698

* web: move Modal.Root fade-down transition into the theme (#1698 review)

Addresses the review note on PR #1753: the `transitionProps={{ transition:
"fade-down", duration: 200 }}` literal was duplicated in both settings modals to
restore the animation `<Modal>` defaults to but `Modal.Root` doesn't inherit.
Move it to a `ThemeModalRoot` (`Modal.Root.extend`) registered under the
`ModalRoot` theme key, mirroring the existing `ThemeScrollAreaAutosize`
precedent. Both call sites drop the literal; any future compound `Modal.Root`
now animates consistently with every plain `<Modal>` from one source of truth.

tui: detect array-of-enum on items.enum alone (#1752)
* tui: detect array-of-enum on items.enum alone (#1751)

The TUI schemaToForm array-of-enum branch was nested under an outer
`if (property.enum)` guard, so a standard array-of-enums schema —
`{ type: "array", items: { enum: [...] } }` with no top-level `enum` — never
reached it and fell through to a plain string input. The web SchemaForm already
guards on `items?.enum` alone; this aligns the TUI with it.

Restructure the enum handling so the array-of-enums case keys on
`property.type === "array" && property.items?.enum` independently of a top-level
`enum`, falling back to the single-select `property.enum` branch otherwise. The
enumNames labeling from #1691 applies unchanged.

Tests: the array-of-enum cases now use the standard `items.enum`-only shape
(dropping the redundant top-level `enum` the old nesting required), plus a case
asserting a redundant top-level `enum` still works.

Closes #1751

web+tui: honor enumNames in enum forms (#1750)
* web+tui: honor enumNames in enum forms (#1691)

Legacy titled enums (`enum` + non-standard `enumNames`) rendered their raw
wire values instead of the human-readable titles in both the web SchemaForm
and the TUI schemaToForm builder, so a user picking "pet-1" had no idea it
meant "Cats".

Web (SchemaForm.tsx): extract a `toEnumData` helper that zips `enum` with
`enumNames` into `{ value, label }[]` when the lengths match, falling back to
bare values otherwise. Use it in both the string-enum and array multi-select
branches (the latter previously inlined the same zip).

TUI (schemaToForm.ts): add `enumNames` / `items.enumNames` to the property
interface and a `toSelectOptions` helper used by the single-select and
array-of-enum branches, labeling by `enumNames[i]` when length-matched and
falling back to `String(val)`.

Both guard on the arrays being the same length: a wrong-length zip would
mislabel options, which is worse than showing raw values. Raw values are
always submitted; only the display label changes.

Closes #1691

Server Settings: disambiguate EMA OAuth credential fields (#1692) (#1749)
* Server Settings: disambiguate EMA OAuth credential fields (#1692)

Under enterprise-managed authorization the OAuth Settings "Client ID" /
"Client Secret" fields hold the *resource authorization server* credentials
(EMA leg 3 — the Test Client from the xaa.dev resource registration), not the
app/IdP pair configured in Client Settings. The unqualified labels sat under a
toggle naming the enterprise IdP, pulling readers toward the wrong pair.

- When enterpriseManaged is on, relabel to "Resource AS Client ID" /
  "Resource AS Client Secret" and add a description naming the resource
  authorization server and pointing the app pair back to Client Settings.
- Document the Scopes delimiter: space-separated (RFC 6749), with a warning
  that commas produce one invalid token, plus a placeholder example.

Adds tests for both label states and the scopes hint, plus an
EnterpriseManagedOAuth story.

- Drop the hardcoded xaa.dev staging host from the resource-AS field
  description (it's a general EMA concept, not env-specific); phrase it as
  "the resource authorization server's registered client credential (EMA leg
  3)". Also trims the copy's overlap with the checkbox description.
- Reuse the existing `enterpriseManaged` const for the EMA Checkbox's `checked`
  prop instead of recomputing `settings.enterpriseManaged ?? false`.
- Update the test assertion and pr-screenshots README/EMA-on screenshot to
  match the new copy.

* Client Settings: mirror EMA disambiguation (IdP-qualified labels) (#1692)

The Server Settings OAuth fields now label the leg-3 resource-AS pair
explicitly; make Client Settings parallel so each modal names its pair and
points at where the other lives.

- Relabel the EMA credential fields to "IdP Client ID" / "IdP Client Secret"
  (parallel to Server Settings' "Resource AS Client ID/Secret"), so the label
  alone disambiguates without relying on the description.
- Add the reciprocal cross-reference to each description: these are the
  enterprise IdP pair (EMA legs 1–2), not the per-server resource authorization
  server credentials, which go in Server Settings → OAuth Settings.
- Update ClientSettingsForm/ClientSettingsModal tests for the new labels; add a
  pr-screenshots section + Client Settings screenshot.

Extensions UI: own Advertised Extensions section + 'Client Advertised Extensions' heading (#1748)
* Settings: move Advertised Extensions to its own accordion section (#1747)

The Advertised Extensions control (added in #1739) lived inside the Options
accordion panel, wedged between "Fetch Lists One Page at a Time" and "Network
Log Size". Promote it to its own top-level "Advertised Extensions" accordion
section (after Options), so the distinct concept — which extensions the
Inspector advertises to this server in its client capabilities — reads as its
own collapsible section.

- ServerSettingsForm: add "extensions" to ServerSettingsSection; move the
  checkbox group into a new Accordion.Item value="extensions". Its description
  moves up into the panel; no behavior change (still folds into
  settings.advertisedExtensions via onAdvertisedExtensionChange).
- ServerSettingsModal: add "extensions" to allSectionsFor so expand/collapse-all
  covers it.
- Tests: the toggle now lives under the new (collapsed-by-default) section, so
  the form tests render it expanded and the modal tests open it first.

Extensions: Connection Info both eras + io.modelcontextprotocol/ui advertisement (Phase 3 of #1633) (#1744)
* Extensions: Connection Info both eras + io.modelcontextprotocol/ui advertisement (Phase 3 of #1633)

Completes the Extensions surfacing and advertises the MCP Apps UI extension.

core/mcp/extensions.ts:
- Add UI_EXTENSION_KEY ("io.modelcontextprotocol/ui") and MCP_APP_MIME_TYPE
  ("text/html;profile=mcp-app") — mirrors of ext-apps' EXTENSION_ID /
  RESOURCE_MIME_TYPE (hardcoded: the constants live on the package's /server
  subpath or an extensionless re-export that doesn't resolve under NodeNext).
- Registry entries gain an optional `advertisement` value; the builder stamps
  it (default {}). Add the `ui` entry, default-advertised with
  `{ mimeTypes: ["text/html;profile=mcp-app"] }` — the Inspector always renders
  App tools. No ext-apps cast needed: the extensions value type is `object`.

ConnectionInfoContent:
- Source server extensions from the negotiated `capabilities.extensions`
  (getServerCapabilities, era-transparent) instead of the modern-only
  discoverResult, so a LEGACY server advertising extensions renders them too.
- Add a two-column "Server Extensions" / "Advertised Extensions" section (the
  Inspector's own advertised map), mirroring the server/client capability
  columns. Drop the now-redundant Extensions row from the modern Discovery
  section (Supported versions stays).

Tests: extensions.test.ts covers the ui entry + advertisement value and the
per-extension enable/disable; ConnectionInfoContent.test.tsx covers legacy
server extensions (no discovery), the advertised-extensions column, and the
em-dash empty states. npm run ci green (the one InspectorView localStorage
failure is a known flake, passes on re-run).

Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5

* Extensions: address Phase 3 review (mime drift-guard, story, exact em-dashes)

- extensions-mimetype.test.ts (integration/node): assert MCP_APP_MIME_TYPE
  equals ext-apps' real RESOURCE_MIME_TYPE (imported) and that the client
  advertises it — a genuine drift guard, replacing the tautological literal
  check in the unit test (which now just asserts the type).
- ConnectionInfoContent Modern story: carry the tasks extension on
  initializeResult.capabilities too, so the Server Extensions row demonstrates
  it (the row now reads negotiated server capabilities, not discoverResult).
- Tighten the em-dash assertions from ">= N" to exact counts (3/3/2) now that
  the two extension sections em-dash by default.

* Extensions: drift-guard UI_EXTENSION_KEY against ext-apps EXTENSION_ID (review)

Address the Phase 3 re-review nit: the extension id was the other half of the
same drift risk (a server keys its Apps lookup on it). Import ext-apps'
EXTENSION_ID from the /server subpath in the node integration test (fine there;
the browser build is what avoids /server) and assert UI_EXTENSION_KEY === it.

* Extensions: clone the registry advertisement so builds never alias it (review)

Address the Phase 3 re-review's optional defensive nit: buildClientExtensions
returned the same object reference as the ADVERTISABLE_EXTENSIONS entry for the
ui advertisement, so an in-place mutation of a stamped value (e.g.
extensions[ui].mimeTypes) could corrupt the registry for later connections.
structuredClone the advertisement on stamp; add a test asserting a mutated
build doesn't leak into the next one. Nothing mutates it today — purely
defensive.

(the new ui advertisement), and only ui after toggling Tasks off and reconnecting.

Extensions: advertised-extensions toggle in Server Settings (Phase 2 of #1633) (#1743)
* Extensions: advertised-extensions toggle in Server Settings (Phase 2 of #1633)

Adds the debugging knob from #1633: users choose which extensions the
Inspector advertises to a server, and a server may register different tools
in response. Builds on Phase 1's registry + advertisedExtensions option (#1738).

Settings + persistence (core):
- InspectorServerSettings.advertisedExtensions + StoredMCPServer field, wired
  through serverList's read/write converters and INSPECTOR_FIELD_KEY_MAP
  (omit-when-empty, byte-stable round-trip).
- validateSettings (remote PUT route): isBooleanRecord guard + carry a
  non-empty map; unknown/malformed rejected.
- App.tsx threads savedSettings.advertisedExtensions into the client options.

UI:
- ServerSettingsForm renders an "Advertised Extensions" group of checkboxes
  driven by ADVERTISABLE_EXTENSIONS; a per-server override wins over the
  registry default. Modal folds a toggle into settings.advertisedExtensions.

Test server + proof:
- composable-test-server extensionGatedTools: a tool registered disabled and
  enabled on `initialized` iff the client declared the mapped extension
  (getClientCapabilities). Legacy stateful leg. Threaded through
  load-config/resolve-config; advertised-extensions-http.json showcase + README.
- Integration test connects legacy with/without the tasks extension advertised
  and asserts the gated tool appears/disappears in tools/list — the acceptance
  criterion, proven end to end, not asserted.

Tests: serverList round-trip (non-empty/absent/empty), ServerSettingsForm
toggle rows, ServerSettingsModal fold, validateSettings accept/reject, and the
integration gating test. npm run ci green (per-file ≥90 gate held).

End-to-end smoke test in the web client against the legacy

Advertised Extensions → Tasks toggle and reconnecting lists only echo — the
server's tool registration changing on the client-declared extension.

* Extensions: reconverge advertisedExtensions to no-override on default (review)

Address Phase 2 review observation #1: toggling an extension back to its
registry default now deletes the override key (and drops the whole map to
undefined when it empties), so the on-disk `advertisedExtensions` reconverges
to the byte-stable "no override" state instead of persisting a redundant
`{ key: <default> }`. Matches the omit-when-default policy the other settings
use. Only a value that differs from the default is persisted.

Adds a modal test asserting the reconvergence (re-checking the sole disabling
override drops advertisedExtensions to undefined).

Tools: x-mcp-header annotation tooling + -32602 unknown-tool rendering (#1632) (#1735)
* Tools: x-mcp-header annotation tooling + -32602 unknown-tool rendering (#1632)

Card 9/10 of the SDK-v2 + New Spec stack. Adds SEP-2243 `x-mcp-header`
tooling to the Tools tab and adjusts result rendering for SDK v2's
unknown-tool behavior, and bumps the SDK to 2.0.0-beta.5.

- **`core/json/xMcpHeader.ts`**: a faithful port of the SDK's (non-public)
  `scanXMcpHeaderDeclarations` — validates every SEP-2243 constraint
  (primitive types incl. `number`, RFC 9110 token, case-insensitive
  uniqueness, statically-reachable `properties`-only chain) and derives the
  mirrored `Mcp-Param-{Name}` params for a kept tool.

- **Excluded tools**: the SDK silently drops tools with invalid annotations
  from `tools/list`. InspectorClient now re-lists the RAW (unfiltered) list
  and scans it to recompute the excluded set with reasons — gated to the
  modern non-stdio era (matching the SDK's gate), recomputed on every
  aggregate refresh, surfaced via a new `excludedToolsChange` event +
  `getExcludedTools()` and `useInspectorClient().excludedTools`. The Tools
  sidebar lists them struck-through under an "Excluded (SEP-2243)" divider
  with the reason on hover.

- **Mirrored args**: ToolDetailPanel shows a "Mirrored request headers"
  section listing each arg → `Mcp-Param-{Name}` (with the browser-omits note).

- **-32602 rendering**: SDK v2 rejects an unknown-tool call with `-32602`
  instead of an `isError` result, which previously rendered nothing. New
  ToolCallErrorPanel renders a thrown tool-call error, with a targeted
  "Unknown Tool" hint for `-32602`.

Adds unit + Storybook + integration coverage (a real modern server with an
invalid-header tool fixture) for every path. `npm run ci`-equivalent checks
green.

Closes #1632

* Respond to review: disambiguate -32602, doc/search nits (#1632)

Addresses the review on PR #1735:

1. -32602 "Unknown Tool" mislabel: `-32602` is generic Invalid params, so a
   known tool called with bad arguments hit the same code and rendered under
   the definitive "Unknown Tool" heading. Replace `isUnknownToolError` with
   `classifyToolCallError(code, message)` → "unknown-tool" only when the
   message names it (not found / unknown tool / …), else "invalid-params"
   (new "Invalid Parameters" heading + schema hint), else "generic".

2. Double pagination walk: expand the `listAllTools` comment to document that
   the excluded-tools recompute is a deliberately un-cached second raw walk
   (doubles list round-trips on modern non-stdio, runs even on a cache-served
   aggregate) — accepted for a debugging tool, no-op on legacy/stdio.

3. Doc nit: `scanXMcpHeaderDeclarations` no longer claims to visit "$ref
   targets" — reworded to note `$ref` is never followed (refs resolve into the
   unreachable `$defs` body).

4. Search nit: the excluded-list filter now matches name AND title, matching
   the main tools filter.

* Tighten unknown-tool matcher to be tool-scoped (#1632 re-review nit)

The re-review noted the -32602 disambiguation was symmetric: broad markers
("does not exist", "unrecognized") could inversely mislabel a genuine
invalid-params message (e.g. "property 'region' does not exist") as "Unknown
Tool". Scope the not-found/does-not-exist family to require the word "tool" in
the same clause (matching the SDK's "Tool <name> not found"); keep "unknown
tool" / "no such tool" as standalone unambiguous markers. Adds a

* Add trigger_invalid_params showcase tool + Invalid Parameters screenshot (#1632)

Adds a `trigger_invalid_params` spec-error trigger to the modern showcase
server: the injector answers its `tools/call` with a real `-32602 Invalid
params` JSON-RPC error whose message does NOT name an unknown tool. This lets
the "Invalid Parameters" branch of the tool-call error panel (added in the
review response) be exercised live, distinct from the unknown-tool `-32602`.

- `SPEC_ERROR_TRIGGERS` gains the `trigger_invalid_params` entry (HTTP 200,
  in-band -32602) + preset registration.
- Enable `injectSpecErrors` on `xmcpheader-modern-http.json` and add the tool.
- README + pr-screenshots README document it; adds the live "Invalid
  Parameters" proof screenshot.

Tasks: io.modelcontextprotocol/tasks extension on modern servers (era fork) (#1731)

* Tasks: modern io.modelcontextprotocol/tasks extension (era fork core)

Core + test-server implementation of the SEP-2663 tasks extension for modern
(2026-07-28) connections, forked from the legacy 2025-11-25 tasks path.

SDK v2 removed all tasks support AND era-gates the tasks/* spec methods out of
the modern era on both the client (outbound) and server (inbound) sides, and its
codec rejects a resultType:"task" result outright. So the Inspector drives the
extension itself: task creation rides tools/call (a modern method) with the
resultType:"task" frame rewritten at the transport to a CallToolResult carrying
the handle in _meta; tasks/get/update/cancel go over a raw-wire request channel
that bypasses the era gate (full modern envelope, string ids, consumed by the
transport). input_required tasks reuse the existing pending-request modal via
fulfilInputRequests, answered with tasks/update. No tasks/list, no tasks/result.

Tab + run-as-task gate on the negotiated extension; the managed task store's
refresh re-polls known handles on modern (no server list). Test server serves
the extension via an Express interceptor (SDK can't) + a shared poll-driven
runtime. Full integration coverage of both eras.

* Tasks modern era: tests + coverage (raw-wire, schemas, era integration)

Adds unit coverage for modernTaskSchemas and the raw-wire request channel
(transport-null guard, send failure, timeout, error response, teardown), plus
end-to-end era integration tests (create/poll/input-required/update/cancel,
synchronous passthrough, unknown-id error, modern store re-poll). Fixes the App
and constructor-capabilities tests for the always-on tasks extension.

* Tasks modern era: offer Run-as-task for any tool + PR screenshots

On modern (SEP-2663) task creation is server-directed — the client declares the
extension once and any tool may return a task — so the Tools screen now offers
'Run as task' for every tool on a modern connection (threaded via a modernTasks
prop through InspectorView → ToolsScreen → ToolDetailPanel), rather than gating
on the legacy per-tool taskSupport. Verified end-to-end in the web UI (remote
proxy): create → poll tasks/get → input_required elicitation → tasks/update →
inline result, plus the unchanged legacy tasks/list/result flow. Adds proof
screenshots.

* Tasks modern era: address two follow-ups (task-input note + ordinary-path auto-poll)

1. The pending-request note now distinguishes a modern task round from an MRTR
   round: a new 'task-input-required' PendingRequestOrigin threads through
   fulfilInputRequests → the pending-request modal → MrtrOriginNote, which shows
   'submitted via a tasks/update request (SEP-2663), not a retry' instead of the
   MRTR retry copy.

2. The ordinary (non-run-as-task) modern callTool path now auto-polls an
   unsolicited task handle: attemptToolCall detects the rewritten handle in the
   result _meta and drives it to termination (get → input_required/update →
   inline result), dispatching task events so the Tasks tab + toasts track it and
   the tool result resolves to the task's final result. The poll loop is shared
   with the streaming path via extracted helpers (submitModernTaskInput /
   modernTaskTerminalOutcome / modernTaskPollInterval).

* Tasks modern era: address review (negotiated envelope version, input-round cap, clarifying comment) + fresh smoke screenshots

Review of #1731:
1. withModernTaskEnvelope now stamps the NEGOTIATED protocol version
   (getProtocolVersion() ?? MODERN_PROTOCOL_VERSION) so the envelope matches the
   MCP-Protocol-Version header instead of a hardcoded constant.
2. A never-completing input_required task is now bounded by MRTR_MAX_ROUNDS in the
   shared submitModernTaskInput (threaded through both poll loops), so a
   non-conformant server can't re-prompt the user forever. New modern_loop_task
   test-server tool + integration test cover the cap.
3. ToolDetailPanel: comment clarifying that per-tool taskSupport:"forbidden" is
   deliberately ignored on modern (task creation is server-directed under SEP-2663).

(The abort-during-poll observation is addressed in the PR reply: the cancel path
uses tasks/cancel and disconnect rejects the in-flight raw request, so the poll
stops; matches legacy.)

Fresh web-UI smoke screenshots (modern connected, task completed, input_required
with the corrected tasks/update note, input completed).

* Tasks modern era: fix uncancelable input-required loop + sticky cancel

Two bug fixes reported during manual testing of the tasks era-fork (#1631):

1. A modern task paused at `input_required` (e.g. `modern_loop_task`, which
   never advances) could not be cancelled: the poll loop blocked on the
   pending-request modal, so `cancelRequestorTask` sent `tasks/cancel` but the
   modal kept re-prompting. Now each modern poll loop registers a per-task
   AbortController (`registerTaskInputAbort`), `cancelRequestorTask` aborts it
   to reject the pending elicitation and unblock the poll, and the embedded
   input requests are tagged with their owning task id
   (`RELATED_TASK_META_KEY`) so the pending-request UI's Cancel action cancels
   the TASK rather than sending a "cancel" answer the server would re-prompt on.

2. On the legacy server, cancelling a task briefly showed CANCELLED then
   flipped to COMPLETED when the in-flight tool call resolved. Cancellation is
   a deliberate terminal decision, so `ManagedRequestorTasksState` now remembers
   cancelled task ids and ignores any later non-cancelled status update.

Also: move the compact task id onto its own line in the embedded monitoring
sidebar so the status badge / Cancel Task control don't wrap; DRY the duplicated
task poll-interval logic into a shared `taskPollInterval` helper.

* Address re-review: sticky cancel on legacy refresh + App cancel-routing test

Re-review of the cancelable-loop / sticky-cancel fix raised two non-blocking
hardening items:

1. The legacy tasks/list refresh() rebuilt the list from the server, honoring
   only dismissedTaskIds — so a cooperative-cancel server that re-lists a
   user-cancelled task as completed could un-stick the cancel on a manual
   Refresh. The refresh path now pins a cancelledTaskIds task to "cancelled"
   (keeping it visible-as-cancelled, matching the live-merge handlers) rather
   than dropping it. Covered by a new state test.

2. Added an App.test.tsx case locking in the user-facing half of the fix: Cancel
   on a task-input-required elicitation calls cancelRequestorTask (not respond).

Resources: subscriptions/listen model on modern servers (era fork) (#1630) (#1730)
Fork resource subscriptions by protocol era: legacy keeps resources/subscribe; modern (2026-07-28) models subscriptions as a filter over one long-lived subscriptions/listen stream with reconnect-by-re-listen (capped backoff), an optimistic Connecting→Listening header badge, and a fix so the browser proxy no longer blocks listen() ~60s.

* Logging: per-request log level on modern servers (era fork) (#1629)

On modern (2026-07-28) servers `logging/setLevel` and the session-scoped
level are gone: the client opts into logs per request via the
`io.modelcontextprotocol/logLevel` `_meta` key, and the SDK does not
attach it automatically, so server logs are silently absent until stamped.

Core (`InspectorClient`):
- `setModernLogLevel(level | undefined)` / `getModernLogLevel()` store the
  opt-in level; `mergeMeta` stamps it on every outgoing request, gated on
  the negotiated modern era so legacy connections are untouched.
- Cleared on disconnect so it can't leak into the next connection.

Web UI:
- `LogControls` forks on `protocolEra`: legacy keeps the `logging/setLevel`
  selector + Set button; modern shows a per-request opt-in Select (Off +
  levels, applied immediately) with copy explaining logs arrive on the
  originating request's stream.
- Threaded `protocolEra` / `modernLogLevel` / `onSetModernLogLevel` through
  LoggingScreen and InspectorView from App.

Tests: unit coverage for the modern LogControls/LoggingScreen fork;
integration coverage proving the `logLevel` `_meta` is stamped on a real
modern server once opted in (and not on legacy).

* test-servers: logging era-fork showcase configs + proof screenshots (#1629)

Add two manual-testing configs and README docs for the logging era fork:

- logging-legacy-http.json: plain streamable-HTTP server with `logging: true`
  and a `send_notification` tool. The Logs tab shows the legacy session-scoped
  "Set Active Level" selector + Set button; calling the tool streams logs.
- logging-modern-http.json: same, with `transport.modern: true`. Connect with
  Protocol Era = Modern and the Logs tab shows the per-request opt-in control;
  the client stamps `_meta["io.modelcontextprotocol/logLevel"]` on every
  request (visible in the Network tab request body).

pr-screenshots/ documents the verified behavior end-to-end against both real
servers: the legacy control with logs streaming, the modern per-request
control, and the modern tools/call request body carrying the stamped logLevel
_meta.

* test-servers: send_notification emits via per-request notifier so modern logs stream (#1629)

The `send_notification` tool sent its `notifications/message` through the
global `server.server.notification()`. On the modern (2026-07-28) stateless
leg that isn't tied to the in-flight request, so the SDK answered the tool
call with plain JSON and dropped the log — nothing reached the Inspector's
Logs panel.

Prefer the per-request `extra.sendNotification` (rebuilt from
`ctx.mcpReq.notify`): scoped to the current request, it makes the SDK upgrade
the response to SSE and stream the log back on the originating request's
stream. Falls back to the global notifier (legacy path / no per-request
context). Verified end-to-end: opting in via the Logs-tab "Log Level per
Request" control and calling send_notification now streams the entry on the
modern server; legacy behavior unchanged (server-notification integration
tests green).

README documents the modern logging showcase and the caveat that this test
server streams whenever a tool emits — the SDK beta strips the per-request
envelope from the handler context, so the tool can't gate on the client's
logLevel opt-in (the client-side `_meta` stamp #1629 owns is still fully
visible in the Network tab).

* test-servers: send_notification uses SDK request-scoped log() → spec-faithful modern gating (#1629)

The previous fix routed `send_notification` through `extra.sendNotification`
(`ctx.mcpReq.notify`), which streams on the modern leg but emits
unconditionally — the log showed up even when the client hadn't opted in via
the per-request `logLevel`.

The SDK already provides the correct primitive: `ctx.mcpReq.log(level, data,
logger)` (added in `McpServer.buildContext`). It applies the era-correct
threshold gating itself — on the modern (2026-07-28) leg it reads the
per-request `logLevel` opt-in from the request envelope and drops the message
when the client didn't opt in or the level is below the requested severity; on
legacy it honors the session level from `logging/setLevel` — and emits through
`notify`, so the modern response still upgrades to SSE and the log rides the
originating request's stream.

Surface it as `extra.log` (`toHandlerExtra` maps `ctx.mcpReq.log`) and have
`send_notification` prefer it, falling back to the global notifier for callers
without per-request context. Verified end to end: opting in via the Logs-tab
"Log Level per Request" control stamps `logLevel` in the request `_meta` and
streams the log; setting it back to Off omits the key and the server gates the
log (plain JSON response, no notification). Legacy server-notification
integration tests still green. (No SDK change needed — the earlier apparent
gap was our test server using the wrong low-level API.)

* web+core: add "Log Level per Request" as a per-server setting, defaulting to on (#1629)

Adds the modern per-request log level as a persisted Server Settings option
(Options → "Log Level per Request", below Protocol Era), so a server can opt
into logs by default instead of the Logs-tab control starting at Off.

- types.ts: `ModernLogLevel` (`"off"` | the 8 levels), `DEFAULT_MODERN_LOG_LEVEL`
  = "debug" (default-on so a modern connection surfaces server logs out of the
  box), `MODERN_LOG_LEVELS`, and an `isModernLogLevel` guard. Field added to
  `InspectorServerSettings` and `StoredMCPServer`.
- serverList.ts: round-trip the field (lift on read, omit-on-default on write,
  drop unknown literals) mirroring `protocolEra`; add to the persisted field
  allowlist.
- remote/node/server.ts: validateSettings accepts/validates it and the
  normalize path drops a malformed literal.
- inspectorClient.ts: the constructor seeds `modernLogLevel` from the setting
  (`"off"` → not opted in), so a modern connection stamps the level from the
  first request without UI interaction. mergeMeta still gates on the modern era.
- ServerSettingsForm/Modal: a Select (Off + 8 levels) with a modern-era
  description. App seeds the live Logs-tab control from the setting on connect
  so the two stay in sync.

Tests: form Select (default/onChange/off/reflect), modal handler, serverList
round-trips, route validation (accept/reject/drop), and constructor seeding
(seeded level stamped from the first request; "off" opts out). The prior
modern-era "stamps once set" test is updated for the new default-on behavior.
Coverage gate green.

  there is no root format script; formatting is per-client).

  Network-tab export debugging artifact accidentally committed in ca2aa526
  (flagged by review).
- Broaden the .gitignore debugging-artifacts section with

* test: add modern-era log delivery + gating e2e tests (#1629)

The modern-era suite covered the client-side `_meta` logLevel stamp but not
that a log actually flows back — the legacy suite already has that
(`should receive server-initiated notifications via SSE/streamable-http`), so
the modern side was the gap.

Add two live e2e tests against a modern (`createMcpHandler`) server serving the
`send_notification` tool with `logging: true`:
- opted-in (server setting = a level): calling the tool delivers a
  `notifications/message` over the request's SSE stream, with the right
  level/logger/data.
- not opted in (setting "off"): the tool still returns a result, but the server
  gates the log — no `notifications/message` is received.

This exercises the full path end to end: the client seeding + `_meta` opt-in,
and the server's `send_notification` → `ctx.mcpReq.log` era-correct gating.

Verified with the full `npm run ci` (green across all clients).

* web: hide the modern "Log Level per Request" setting on legacy connections (#1629)

The per-request log level is meaningless on a legacy server (which uses
logging/setLevel), so hide it in Server Settings when the era is legacy:
- protocolEra pinned to "legacy" → hidden (no connection needed), or
- protocolEra "auto" that negotiated legacy at connect time → hidden.

It stays visible for a pinned "modern" server, and for an "auto" server that is
either not yet connected (era unknown) or resolved to modern.

Threads the negotiated era down: App passes `negotiatedEra` to
ServerSettingsModal only when the settings target is the live-connected server
(`connectionStatus === "connected" && settingsModalTargetId === activeServerId`);
the modal forwards it to ServerSettingsForm, which gates the control on
`configuredEra === "modern" || (configuredEra === "auto" && negotiatedEra !== "legacy")`.

Tests: visibility matrix on the form (legacy hidden; auto+legacy hidden;
auto+unconnected and auto+modern and modern shown) and a modal hide case; the
existing modern-log tests now base on a modern-era settings object. Verified in
the browser (legacy hides, switching to modern reveals it reactively) and with
the full `npm run ci` (green across all clients).

* Thread cacheMode through managed list refresh via SDK cache-aware verbs (#1721)

Manual/auto refresh of tools/resources/prompts now forces a cache-bypassing
round trip on modern servers, delivering the raw-request cacheMode control
deferred from #1628.

The InspectorClient list/read path uses the SDK's single-page `client.request`
verbs (for pagination debugging), which never consult the SDK response cache —
so `cacheMode` was inert there. This adds a separate aggregate path that routes
through the SDK's cache-aware high-level verbs, where `cacheMode` is honored:

- InspectorClient: new `listAllTools/Prompts/Resources/ResourceTemplates(
  { cacheMode, metadata })` that call `client.listTools()` etc. (all-page
  aggregate + SEP-2243 x-mcp-header exclusion + cache consult/write). A shared
  `getCacheableRequestOptions` / `aggregateListParams` back all four.
- InspectorClientProtocol: the four `listAll*` methods added.
- ManagedListState: delegates page walking to the SDK verb (config `fetchPage`
  loop → `fetchAll`); `refresh(metadata?, cacheMode?)` threads cacheMode. A
  `list_changed` auto-refresh bypasses the cache (`cacheMode: "refresh"`).
- Managed hooks: user-initiated `refresh()` passes `cacheMode: "refresh"`, so
  the existing per-tab Refresh buttons become genuinely cache-bypassing — no
  App wiring change. Connect-time load stays default (`'use'`).

The single-page `listTools(cursor)` primitive is unchanged; the paged hooks
still surface per-page `nextCursor`.

* Single-page list pagination: sidebar toggle + server setting (#1721)

Delivers the deferred single-page fetch UI: Tools/Resources/Prompts can be
loaded one page at a time instead of auto-aggregating every page — a defensive
option for servers with very large lists.

- New `singlePageLists` server setting (persisted, server-wide), plumbed through
  ServerConfig/InspectorServerSettings, serverList convert/default, the node +
  remote settings paths, and the Server Settings form ("Fetch Lists One Page at
  a Time").
- New `ListPaginationControls` element (a "Single page" switch + "Load next
  page" button + "N pages loaded" status) rendered in each list sidebar; the
  toggle edits the setting live (optimistic) and persists it.
- The paged state stores (PagedTools/Prompts/ResourcesState) now own loading:
  they auto-load page 1 on connect in single-page mode and track nextCursor +
  page count as observable state; the managed stores skip their all-page walk
  in single-page mode (so nothing is over-fetched) while still lighting the
  list-changed indicator. `usePaginatedList` selects the display source and
  pagination controls per mode — pure, no data-loading in React effects.
- Refresh is mode-aware: reload page 1 in single-page mode, refetch the whole
  aggregate otherwise. Sidebars widened 340→360 so the controls don't crowd
  list entries.
- Test server: `test-servers/configs/pagination-http.json` (12 tools/resources/
  prompts, page size 4 → 3 pages each) exercises the flow end to end.

* Address @claude review: template load, double-click guard, auth recovery (#1721)

- Fix: resource templates never loaded on connect in single-page mode. The
  connect-time all-page skip now applies only to lists with a paged counterpart
  (new `deferInSinglePage` flag on ManagedListConfig; false for resource
  templates), so templates still aggregate on connect regardless of the setting.
- Guard `PagedTools/Prompts/ResourcesState.loadPage` against a concurrent load
  (fast double-click on "Load next page") so the same page can't be appended
  twice; the in-flight load owns the cursor and the second call is a no-op.
- Thread ambient auth recovery through the single-page refresh, Load-next-page,
  and mode-switch loads (they previously bypassed it) — usePaginatedList's
  onRefresh/onLoadMore now return their promises so App can wrap them.
- Drop the misleading "aggregated list" wording from the paged-store docs.

Tests added for each; npm run coverage green.

`singlePageListsOverride` is now cleared and the live client setting rolled back
(the effect only clears the override when the persisted value changes, which
doesn't happen on failure), so the UI and client reflect what's on disk rather
than the failed edit. Added an App test for the revert path.

* Fix single-page Refresh not clearing list-changed indicator + UI polish (#1721)

Round-3 review fix (blocking): in single-page mode a `list_changed` lights the
list-changed indicator, but the single-page Refresh reloads page 1 of the paged
store and bypassed `useManaged*.refresh()`, so the indicator was never cleared.
Expose `clearListChanged` from useManagedTools/Prompts/Resources and call it in
the single-page branch of onRefreshTools/Prompts/Resources. Tests added.

UI polish (user feedback on the sidebar control):
- Rename the switch label "Single page" → "Paginated".
- Put "Load next page" on the same row as the switch, space-between (switch
  fully left, button fully right).
- Move the "N pages loaded" status to its own line below the row, centered.
- Hide the whole control once the list is known to be a single page
  (single-page mode, page 1 loaded, no nextCursor) — nothing to paginate.

pr-screenshots refreshed to the new layout.

* Rename the singlePageLists setting to paginatedLists for clarity (#1721)

`singlePageLists` read backwards from the "Paginated" switch label (it sounds
like paginated=false). Rename the server setting to `paginatedLists` with the
same value meaning — true = paginated/one-page-at-a-time, false = aggregate-all
— and follow through on the related identifiers for consistency:

- Setting field `paginatedLists` across ServerConfig / InspectorServerSettings,
  serverList convert/default, node + remote settings paths, and the form/modal
  callbacks (onPaginatedListsChange).
- `usePaginatedList` / `ListPaginationControls` prop `singlePage` → `paginated`,
  `onSinglePageChange` → `onPaginatedChange`.
- `ManagedListConfig.deferInSinglePage` → `deferWhenPaginated`.
- App state (paginatedListsOverride, onTogglePaginatedLists, …) and all
  tests/fixtures + mode-referring comments.

"single-page" wording that denotes the SDK's one-page `client.request` verb
(inspectorClient) is intentionally left as-is. Purely a rename — no behavior
change; unit + integration + cli + tui + coverage all green.
