chore(deps): migrate to eslint 10 to clear the brace-expansion DoS advisory (#1900)
* chore(deps): migrate to eslint 10 to clear the brace-expansion DoS advisory (#1838)

eslint 9 pulled `minimatch@3` → `brace-expansion@1.1.16`, which carries
GHSA-mh99-v99m-4gvg (high, DoS via unbounded expansion length). It appeared in
all five lockfiles — the root plus each of the four clients, none of which is an
npm workspace, so all five had to move together.

Deferred from the pre-2.0.0 sweep because it is dev-scope, not attacker-
controlled, and a major bump across five packages was the wrong thing to attempt
immediately before an irreversible publish. This is that work.

## What moved

- `eslint` `^9.39.4/5` → `^10.8.0` and `@eslint/js` → `^10.0.1`, in all five
  manifests.
- `eslint-plugin-react-hooks` `^7.0.1` → `^7.1.1` in web and tui. Required, not
  cosmetic: 7.0.1's peer range stops at `^9.0.0`, so installing it alongside
  eslint 10 fails `ERESOLVE`.
- Everything else already declared eslint 10 support and stayed put:
  `typescript-eslint@^8.56.1` (`^8.57 || ^9 || ^10`),
  `eslint-plugin-react-refresh@^0.5.2` (`^9 || ^10`),
  `eslint-plugin-storybook@^10.2.19` (`>=8`).

## Config migration

None was needed. All five configs were already flat (`eslint.config.js` with
`defineConfig`/`globalIgnores` from `eslint/config`), which is the format v10
keeps and the only one it still supports. The root config's `core/` and shared-
surface blocks — including the `_`-prefix `argsIgnorePattern` /
`varsIgnorePattern` / `caughtErrorsIgnorePattern` — are unchanged and still gate
`lint:core` and `lint:shared`.

No rule was disabled, downgraded, or scoped away to make the new eslint pass.
v10 surfaced 21 real violations across three rules; all 21 are fixed in the code.

### `preserve-caught-error` (new in `eslint:recommended`) — 15 sites

A `throw new Error(msg)` inside a `catch` silently drops the original error.
Each now passes `{ cause }`, so the underlying failure survives into the chain.
Messages are unchanged, so nothing that asserts on them moves. 12 in `core/`,
2 in `clients/cli`, 1 in `test-servers/src`.

### `no-useless-assignment` (new in `eslint:recommended`) — 2 sites

`clients/cli/src/cli.ts`'s `optionArgs` and `test-servers/src/test-server-oauth`
's `valid` were initialized and then unconditionally overwritten on every path.
Both are now declared without the dead initializer; TypeScript's definite-
assignment analysis covers the remaining paths.

### `react-hooks/set-state-in-effect` — 8 sites (web)

These were false negatives the plugin fixed in 7.1.0, not a rule we newly opted
into: `set-state-in-effect` has been `error` in `flat/recommended` since 7.0.1,
and the web config has always extended it. Every one was the same anti-pattern —
resetting or re-syncing local state from a prop inside a `useEffect`, which
paints the stale value for one frame and then renders again to correct it.

All eight now use a new `useValueChange(value, onChange)` hook
(`clients/web/src/hooks/useValueChange.ts`), which is React's documented
"adjusting state during render": compare against the previous render's value
with `Object.is` and call back *during* render, so React discards the
in-progress output before it reaches the DOM.

- `MrtrConversation`, `ProtocolEntry`, `TaskCard` — mirror `isListExpanded`.
- `NetworkEntry` — same mirror, plus the "Reveal in Network" force-open. The
  reveal's rAF scroll stays an effect (real external-system work); only the
  `setIsExpanded(true)` moved. `isExpanded` is now seeded from
  `isListExpanded || revealed`, since a render-time sync fires on change and so
  cannot cover an entry that mounts already revealed.
- `PromptArgumentsForm`, `ResourceTemplatePanel` — reset on template/prompt
  switch.
- `ServerConfigModal` — reset on open. Keyed on `opened ? initial : undefined`,
  which collapses "opened flipped" and "initial changed while open" into one
  value; `initial` is already memoized, so it cannot thrash.

`useValueChange` has its own test file, and `ServerConfigModal` gains an
open→edit→close→reopen test (the close leg was previously untested, which is
what left the new guard uncovered).

## Advisory delta

`npm audit`, per package, before → after:

| Package             | before                     | after                      |
| ------------------- | -------------------------- | -------------------------- |
| root                | 9 (1 low, 6 mod, 2 high)   | 8 (1 low, 6 mod, 1 high)   |
| `clients/web`       | 19 (3 low, 6 mod, 6 high, 4 crit) | 17 (3 low, 6 mod, 4 high, 4 crit) |
| `clients/cli`       | 6 (2 low, 4 high)          | 4 (2 low, 2 high)          |
| `clients/tui`       | 4 (1 low, 3 high)          | 2 (1 low, 1 high)          |
| `clients/launcher`  | 3 (3 high)                 | 1 (1 high)                 |

`brace-expansion` is gone from all five — `eslint@10` resolves `minimatch@10` →
`brace-expansion@5.0.9`. Dropping `@eslint/eslintrc` (removed in v10) also took
`js-yaml` with it, clearing GHSA-52cp-r559-cp3m (high) from all four clients as
a bonus. The remainder are unrelated and tracked separately.

`npm run ci` passes end to end — validate, the per-file ≥90 coverage gate, the
build gate, all five smokes (including `smoke:tui`, run locally on a real TTY),
and 462 Storybook tests.

Also documents the effect rule in AGENTS.md and mirrors it into
`.github/copilot-instructions.md`, since it is now something a reviewer cites.

* docs: state useValueChange's referential-stability requirement (#1838)

Copilot review on #1900: the hook compares with `Object.is`, so an object or
array literal rebuilt in the component body compares unequal every render.
Because the callback is what updates state, that is not merely a wasted render —
it is an infinite loop.

Every current caller passes a primitive (`boolean`, `string`) or an already-
memoized value, so nothing changes behaviorally. But the hazard was implicit,
and the next caller is the one it would bite.

Documented on the hook itself, and one clause added to the AGENTS.md rule with
its mirror in `.github/copilot-instructions.md`. No runtime guard: the
requirement is the same one a `useEffect` dependency array carries, and here the
failure is loud and immediate rather than silent.

`npm run ci` passes.

* fix(cli): stop asserting the --tool-args-json catch binding is an Error (#1838)

Copilot review round 2 on #1900: the `--tool-args-json` parse handler formatted
its message with `(e as Error).message`. A `catch` binding is `unknown`, so that
cast is an assertion rather than a check — a thrown non-Error would render
`--tool-args-json is not valid JSON: undefined`, which points the user at
nothing.

`JSON.parse` does only throw `SyntaxError` today, so this is not a live bug. But
the cast is the kind AGENTS.md asks us not to leave unjustified, the same
handler was already being touched here to add `{ cause: e }`, and every other
site in this PR uses the guarded form. Now it does too.

`npm run ci` passes.

* docs: require useValueChange's onChange to be render-pure (#1838)

Copilot review round 3 on #1900: `onChange` is called during render, so it is
bound by render-phase purity — and the web client mounts under `StrictMode`,
which deliberately double-renders in development. A callback doing anything
external would run an unpredictable number of times, and concurrent React can
abandon an in-progress render entirely.

Every current caller already passes a callback that only calls `setState`, so
nothing changes. But "runs during render" is the whole point of the hook and the
constraint that follows from it was left implicit.

Stated on the hook, with the same clause in the AGENTS.md rule and its
`.github/copilot-instructions.md` mirror. All three now point at `NetworkEntry`
as the worked example of the split: the reveal's force-open is a state update
and lives in `useValueChange`, while its `requestAnimationFrame` scroll stays a
`useEffect`.

`npm run ci` passes.

feat(web): enforce localhost-only binding; expand loopback origin allow-list (#1796)
Closes #1795.

Enforce localhost-only binding in code (the "never 0.0.0.0" rule was only a spec note): refuse an all-interfaces HOST — across every spelling the OS binds as the wildcard (inet_aton decimal/octal/hex, IPv6, IPv4-mapped, zone-scoped, IDNA/Unicode) — unless DANGEROUSLY_BIND_ALL_INTERFACES=true (Docker's sanctioned opt-in). Fixes the reported stdio-connect 403 by expanding the default loopback origin allow-list to all three interchangeable forms.

Hardening surfaced across an extended review: closes an IDNA/fullwidth wildcard bypass, a blank-ALLOWED_ORIGINS fail-open, and the CLI/TUI OAuth-callback wildcard bind (loopback-only now, RFC 8252); canonicalizes the origin allow-list the way a browser does; derives frame-ancestors from the real embedder list (IPv6-literal exclusion verified in headless Chromium); strictPort on all three bind points; and preserves the CLI exit-code map + JSON envelope through the mcp-inspector --cli launcher path. Shared host normalization lives in core/node/hostUrl.ts. Docs + tests + smokes throughout.

Guided-auth removal, OAuth smoke testing, and TUI/CLI support (#1531)
* refactor(web): update OAuth E2E tests to use new authentication method

- Replaced `runGuidedAuth` with `authenticate` in the InspectorClient OAuth end-to-end tests to support quick authentication with CIMD pre-registration.
- Updated comments to reflect the change in authentication method and its support for HTTP test metadata URLs.
- Ensured that the tests continue to validate the expected authorization URL after the change.

Additionally, imported `ensureCimdClientRegistration` in the OAuthManager to streamline client registration during the authentication process.

* Guided-auth removal, OAuth smoke testing, and TUI/CLI support

* Added CLI OAuth runner flags tests

* Added clarifying comment on port 0 binding

* README notes on TUI oauth callback port, prettier fixes for CLI tests

* CIMD validation uses inline like EMA IdP

* Fixed TUI test failures from merge

* test: bring 5 OAuth files over the 90 per-file coverage gate

The guided-auth-removal work added/touched several files that fell below
the repo's >=90 per-file coverage gate (npm run coverage). CI doesn't run
the gate (it's local-only), so validate + test:integration passed while
these gaps slipped through. Bring them all back over the line:

- core/auth/node/runner-oauth-callback.ts: test bad-URL/non-http-scheme
  throws, no-port->80 default, and IPv6 hostname bracketing. Annotate the
  provably-dead guards (empty host, out-of-range port, String(err)
  fallback, pathname "/" fallback) -- all rejected by new URL() upstream --
  with justified v8 ignore comments instead of lowering the gate.
- core/auth/cimd.ts: test the AS-doesn't-support-CIMD early return.
- core/react/useClientSettingsDraft.ts: test the functional-updater path,
  the stale-onChange-after-close prev===null guard, and the
  timer-fires-after-close value===null guard.
- ClientSettingsForm.tsx: test the CIMD checkbox toggle and CIMD URL clear.
- clients/tui/src/utils/oauthDisplay.ts: test static/dcr registration
  kinds, the expired IdP session, and the configured-scope/empty-scope
  branches of formatScopes.

npm run coverage now passes (exit 0) across web, cli, tui, launcher.
