test: discriminate --protocol-era wiring against a modern-only server (#2208)
The legacy and auto e2e cases both connect to the legacy stdio fixture whether or not the flag reaches negotiation, since auto falls back. Run initialize against an HTTP test server that rejects the legacy handshake: the default must fail, and --protocol-era modern must connect and report the 2026-07-28 protocol version. Deleting the serverOptions assignment in cli.ts now fails this case (Copilot review, PR #2372).

feat: add --protocol-era launch flag for ad-hoc servers (#2208)
An ad-hoc --server-url / command launch always negotiated the legacy era, because protocolEra was only settable per server in mcp.json. A wrapper that mints a short-lived bearer token therefore had to write that token to disk to exercise a server under auto or modern. --protocol-era <legacy|auto|modern> now feeds settings.protocolEra in all three clients through a shared parseProtocolEra coercer: - CLI/TUI overlay it in loadServerEntries alongside --header, onto an ad-hoc target and onto a --catalog/--config entry for that run. - Web stamps it on the in-memory ad-hoc entry, which the backend lifts into settings like headers; as with --header it is rejected alongside --catalog/--config, but unlike --header it applies to stdio too.

feat: bound connect attempts with a 30 s default connectionTimeout (#2320)
connectionTimeout defaulted to 0, which InspectorClient.connect() read as "no bound at all" — so out of the box nothing the Inspector owns bounded a connect attempt, and the only thing ending a hung handshake was the SDK's 60 s per-request timeout on initialize, reporting "Request timed out". - Add DEFAULT_CONNECTION_TIMEOUT_MS (30000) to core/mcp/types.ts. An absent value resolves to it on the client, on disk read, in the web form draft, and in the CLI's header-only settings shell. An explicit 0 keeps its documented meaning (no timeout; --connect-timeout 0) and is now persisted so the opt-out round-trips; the default is the omit-sentinel, as for taskTtl. - Key the post-timeout transport teardown to the timer actually firing, not to connectionTimeout > 0 — otherwise a non-zero default would tear down every failed connect, including a recoverable 401 whose transport the auth recovery holds open. - The timeout message names the bound and where to raise it: "Connection timed out after N ms. To accommodate a slower server, you may increase the timeout value in Server Settings." - The CLI's UNREACHABLE classifier now matches that message.

fix: address Copilot review round 2, and drop the asyncUtilTimeout raise
The inline finding was a real bug: main() never called the discovery check, so the deny-by-default claim rested on test:scripts happening to run the same comparison — a different command, which `npm run verify:test-timeouts` does not invoke. `failures` is now seeded from it, and a probe config under clients/ was observed to fail the guard. Three suppressed findings, all correct. The afterEach in oauth-interactive restated the shared hookTimeout and labelled it as a round trip, when it only stops a server and unlinks a file; it now carries no budget. The file-lock constants were named for the opposite of what they bound — 90s covers retries running out against a holder that never yields, 60s covers the stale-lock takeover that succeeds — so they are LOCK_RETRIES_EXHAUSTED_MS and STALE_LOCK_TAKEOVER_MS. The browser-timeouts header said 15 budgets; it is 19. Separately, and more importantly: the asyncUtilTimeout raise is reverted, on measurement. Verifying round 2 turned up intermittent 15s timeouts across unrelated unit files, so three arms of three full unit runs were taken in this worktree at comparable load — unmodified v2/main 3/3 green, this change with 5000 producing 1, 4 and 0 timing-out files, and the same change with that one line reverted 3/3 green. A wait that is MEANT to expire spends its whole budget on the happy path, so a 5x raise is a 5x cost on exactly those tests and saturates the worker pool, starving tests that were never slow. Both web setup files therefore state asyncUtilTimeout at the library's own value rather than raising it, which is what #2323's rule actually asks for: a budget nobody chose is the defect, not a budget that is small. The tests that assert absence by letting a wait expire are the real problem and are #2335.

fix: address Copilot review round 1 on #2323
All nine findings taken. Two budgets I had lowered are restored as named exceptions rather than folded into the shared value. cli's e2e child timer goes back to 15s and the two tests that spawn it get E2E_SPAWN_MS = 25s, so the bound carrying the diagnostic still wins without taking load tolerance off the one suite that spawns a real process. App.test.tsx's three-modal sequence keeps THREE_MODAL_SEQUENCE_MS = 20s — a value chosen against an observed failure, which the shared ceiling would have replaced with a general one. Three real false-positive paths in the guard are closed. It now discovers every Vitest config under clients/ and fails on one it is not configured to check — without which "a project with no row is an error" was vacuous, since an undiscovered config yields no project to reject. It strips comments before looking for configure() and requires the exact expected value, so neither a commented-out call nor asyncUtilTimeout: 1 passes. And it compares each resolved project's setupFiles against the site it claims to configure, so deleting a setupFiles entry can no longer leave both projects reported as configured while Testing Library silently reverts to 1000ms. Each has a test, and the setupFiles check was observed to fire against a real deletion. Three stale comments the change had invalidated: main.yml still counted four durable guards, PreviewAnnotations.stories.tsx still said the storybook project had no setupFiles, and the new AGENTS.md rule read as though no Group F row had been settled when this PR settles F6. browser-timeouts.test.mjs gains the purpose header this repo's files carry.

fix: state every test-gate timeout instead of inheriting a library default
Three of the six Vitest projects ran on Vitest's own testTimeout: 5000 and five on its hookTimeout/teardownTimeout: 10000, and all 788 Testing Library waits in the web unit project ran on asyncUtilTimeout: 1000. None of those numbers was chosen here, and all of them were sized for an idle machine rather than for three or four concurrent worktree sessions each running a full local:gate on eight cores. #2292, #2278, #2250, #1942 and #1742 were each that class, diagnosed one site at a time. This is the complement of #1596, not a retreat from it: every fix that issue produced stands, and no race is hidden here. What changes is that a correct, deterministic test is no longer cut off by a budget nobody picked. - vitest.shared.mts exports frozen TIMEOUTS / INTEGRATION_TIMEOUTS; all six projects spread one of them, clients/launcher importing the shared module for the first time to do so. - Both web projects configure Testing Library's asyncUtilTimeout. The storybook one needs its own setup file, deliberately outside .storybook/ and free of setProjectAnnotations so the automatic preview-annotation provisioning (#1898) is untouched. - 28 per-suite restatements of the integration project's own budget are gone, so raising the shared value now moves every site under it. The handful that genuinely differ — cross-process lock contention, a full OAuth round trip — keep their budget as a named constant that says why. - AppRenderer's waitFor no longer asks for exactly its enclosing budget, which it could never win (#2292's shape); cli's e2e child timer drops below the project budget so the bound carrying the diagnostic is the one that fires. - The transition auto-settle's slack term is named RAF_SLACK_MS and raised; the term derived from HEADER_ANIM_MS is untouched. The two answer to different things and must not be scaled as one number. - The 19 Playwright budgets scattered across three web smokes become four named constants in scripts/lib/browser-timeouts.mjs. scripts/verify-test-timeouts.mjs resolves each project through Vitest itself and asserts the budgets, the asyncUtilTimeout sites, and that retry stays unset. It was observed red against the pre-change config: unit/tui/launcher at testTimeout 5000, five projects at hookTimeout 10000, both asyncUtilTimeout sites unmet.

fix: address Copilot review round 17 on #2248
Four of the five findings share one root cause: the tri-state `outcome` added in round 15 was not propagated to consumers, which kept branching on `ok` — true for an `incomplete` report, since nothing that was checked was wrong. - CLI `summarizeSkillVerification` counts off `outcome`, not `ok`, so a truncated walk no longer prints "no conformance errors" one line before exiting SKILL_INCOMPLETE. A mixed failed/incomplete catalog reports both counts rather than letting the louder verdict hide the quieter. - `verifySkills` sets the truncation reason only when entries were actually left unread. A file crossing the byte budget as the FINAL entry stopped nothing, and "Stopped after 3 of 3" both read as a contradiction and demoted a fully-read skill out of `verified`. - The TUI status line switches on `outcome` through a `Record` over the union, so the INCOMPLETE arm is reachable and a fourth outcome would be a type error rather than a silently missing label. - The `incomplete` doc paragraph said it makes `ok` false. It does not, deliberately — corrected, and it now names `outcome` as the thing a consumer must branch on. - The web sidebar composes in the per-URI `duplicate-name` warning, so two colliding skills are badged in the catalog instead of looking clean until one is selected. The suppressed `selfAttempted` finding is stale — fixed in round 16. The existing TUI INCOMPLETE test was passing for the wrong reason: its fixture understated every size, which is itself a mismatch, so the report was `failed` and only the old `ok`-first branch printed INCOMPLETE. It is rebuilt with honest digests and sizes, so truncation comes from the declared-size prefilter and the report is genuinely incomplete.

fix: address Copilot review round 15 on #2248
**Verification is a tri-state now, because two states could not be right.** Round 12 was correct that `ok: true` for a manifest whose unread 513th file may be tampered with is a false pass. Round 15 is correct that forcing `ok: false` calls a server nonconformant for exceeding limits SEP-2640 states as SHOULD NOT, with hosts free to support more — contradicting this module's own rule that a warning never fails a report. Both hold, so: verified -> exit 0 everything checked, everything passed failed -> exit 7 a MUST was broken incomplete -> exit 8 nothing checked was wrong; the walk was cut short `ok` keeps its narrow meaning, `allSkillsVerified` is stricter than `every(r => r.ok)` since it selects the exit code, and `anySkillFailed` separates 7 from 8. A job that tolerates oversized catalogs can allow 8 and still fail on 7. **`manifestKey` still used `JSON.stringify` on the entry** — the same crash I fixed in the TUI in round 12, one file over. **Directory children were navigable outside the skill root.** A server could return `skill://other-skill/...` and clicking it left the tree, with "Up" only comparing equality against the root. Containment is checked on the normalized URI now, and an outside child renders as text rather than a link. Worth recording from the tests: `..` cannot escape the authority, so `skill://a/nested/../x.md` resolves back inside and must stay navigable. **The TUI matched report rows by raw URI**, which missed a row recorded under an equivalent spelling while `extraReportFiles` suppressed it as covered. Normalized, like the membership test beside it.

fix: address Copilot review round 7 on #2248
Four findings. **The CLI dropped what it promised to print.** `getSkill` transforms the `skills/get` envelope to a `SkillEntry`, so every other member the loose schema accepted was gone before the CLI saw it — including the `ttlMs` / `cacheScope` SEP-2640 explicitly leaves open. The code contradicted a comment two lines above it saying a CLI whose contract is "print the result" must not reshape one. `getSkillResult` returns the envelope whole; `getSkill` is a one-line unwrap over it, which matches the callers: the UIs want the entry, the CLI wants the result. **The frontmatter verdict and the digest came from different reads.** The preview fetch and the Verify fetch are separate `resources/read` calls, so a resource changing between them could pair a verified digest with a frontmatter verdict for other bytes. `VerificationState.entryText` now holds the SKILL.md as the verification read it, written in the SAME state update as the verdict — a separate write was clobbered, because `write` returns a fresh object and drops anything not named in it. The preview stays the fallback so a reader who has not clicked Verify still gets the check. **The Conformance badge excluded the frontmatter findings** it renders, so it said `0 error(s)` above a red mismatch. Digest and size mismatches stay in their own badge: "the listing is wrong" and "the bytes are wrong" are different answers. **A repeated skill URI collided two React keys** in the TUI list, in a pane whose job is to show both entries. Index-keyed like the manifest rows. The web fixture also gains its collision pair in the served-file lookup — without it they were handed another skill's SKILL.md, which the badge fix correctly began reporting as a frontmatter error.

fix: address Copilot review round 1 on #2248
Five findings, all real. **Critical — `verifySkills` selected `contents[0]`.** These bytes are hashed against the file's advertised digest, so accepting a block the server labelled something else verifies one file's content against another file's digest, and can report that as `verified`. A false pass is worse than a missing check. `contentsFor(result, uri)` now selects by NORMALIZED identity, which keeps the canonicalized-echo case that motivated the original code while rejecting an unrelated block, and reports a read error when nothing answers for the URI. This is what `onReadSkillFile` already did; the two paths hash bytes against digests and must not disagree about which bytes. **`skills/get` was dispatched without the extension gate** that `skills/list` had. Hoisted into `assertSkillsSupported` so the two cannot drift — declaring the extension commits a server to both. Without it, an undeclared server's -32601 is indistinguishable to a script from the -32602 a declared server returns for a URI it does not serve. **The TUI could strand a user on a hidden Skills tab.** The tab left the bar when the gate went false but `activeTab` did not, so the pane kept rendering for a server that never declared the extension. Reset to `info`, following the Auth precedent — additionally gated on `connected`, because this gate reads a server declaration and would otherwise fire during a reconnect. **The TUI keyed a verdict by URI**, so a refresh replacing the manifest under the same URI left hashes computed for the previous snapshot describing the new one. Keyed on the entry now, as the web screen already was. **A failed "Load more" discarded the pages on screen and the retry cursor.** Both are preserved now, and the success and failure paths share one staleness-guarded `commit` helper so they cannot drift on which results they may write — which is how they came to disagree. Two nits: the six-skill counts. The docs sentence was more wrong than reported (five awkward skills of six, three outright violations) and is rewritten rather than renumbered.

feat: Skills extension phase 3 — CLI, TUI, directory reads, frontmatter check
Closes #2248. Completes SEP-2640 support across all three clients, and closes the one obligation #2234 deliberately left open. - `checkSkillFrontmatterMatch` compares a served SKILL.md's own YAML frontmatter against the entry the listing advertised, field by field. No digest can cover this: a digest is taken over the bytes the server served, so it proves the file was not altered in transit and says nothing about whether the listing described it honestly. Needs a real YAML parser; `yaml` was already a root dependency, so this adds no package — but it does newly put it on core/'s import graph, hence the three bundler `external` lists. - `resources/directory/read`: result schemas defined against the normative text, `InspectorClient.readResourceDirectory`, a Directory section on the Skills screen, and `--method resources/directory/read` in the CLI. The client refuses the call locally when the server did not declare `directoryRead`, which is the SEP's MUST NOT. A child the directory lists but the entry does not is marked `not listed` rather than merged into the manifest — the SEP calls a directory result a live observation and forbids treating it as extending the manifest. - CLI: `skills/list`, `skills/get` and `resources/directory/read`, plus `--verify` — one NDJSON report per skill, a summary on stderr, exit 7 on a violation. Reads are sequential; a conforming manifest may declare 512 entries. - TUI: a Skills pane, shown only when the server declares the extension. Each row carries its conformance verdict as a glyph as well as a colour, since the pane is read over ssh and through script(1). Enter verifies. - `verifySkills` re-throws `AuthRecoveryRequiredError` rather than recording it per file: it says the session's authorization expired, so absorbing it would report N identical read failures and swallow the error the TUI and the web commands key off to reauthorize. Two open questions settled, both in code comments where they will be found: `skills/get` carries no caching attributes because SEP-2640 leaves the question open in as many words, so requiring them would fail a conforming server; and there is no `PagedSkillsState` because every consumer of this list is a whole-catalog verdict — computed over page one of three, "this server's skills conform" is not merely partial but wrong. The fixture grows two skills, both for checks that were otherwise undemonstrable: `lying-listing` (listing and file disagree, digest still verifies) and `stale-manifest` (serves a file its manifest does not declare).

test(auth): stub the clock in both floor regression tests
Copilot round 3 on #2256: both detectors were one-sided. Each measured the sub-floor remainder against the real clock, so a preempted worker overshoots the deadline, the remainder goes negative, and the unfixed `remainingMs <= 0` bound takes the same branch and prints the same message — the test passes on an implementation with no floor. It could never fail wrongly, but it could silently stop testing anything, which on a flake fix is the wrong half of that guarantee to keep. Both now stub `performance.now()`: the web case advances it inside the fetch so the second grant's remainder is exactly MIN_REVOCATION_REQUEST_BUDGET_MS - 1, and the CLI case freezes it so the remainder at the check is the budget itself. Positive and under the floor on every machine, which is the only state that separates the two bounds. Verified as detectors with the clock stubbed: reverting the core floor gives 1 failed / 57 passed, reverting the CLI floor 1 failed / 14 passed.

test(cli): pin the CLI's own minimum-budget floor
Copilot round 1 on #2256: the `budgetMs: 0` case passes under the old `remainingMs <= 0` bound too, so nothing in the CLI suite detected the floor added to `sendPlans`. The new case gives it a budget that is positive and below the floor, and asserts on *this loop's* exhaustion message — the one naming the server URL. That distinction is the test: with the floor removed the plan is handed a 4ms budget and core's identical floor declines it one level down, so a bare "budget was exhausted" match passes either way. Verified as a detector — 1 failed / 14 passed with the CLI floor reverted, 15 passed with it.

fix: address the four suppressed findings from review round 20 (#2144)
Copilot reported "no new comments" again, with four real findings in its suppressed block. - The web in-flight lock was global, so a pending clear for server A silently swallowed a click on server B's — even though the callback explicitly supports clearing a non-active server. Keyed by server id now. - `else if (!isActive)` skipped the resume-snapshot cleanup when the target IS active but has no client yet, which is reachable while a session is being built or torn down. The clear then emptied storage and left stale OAuth recovery state pointing at credentials that no longer existed. - `revocationAuthMethods` returned `[]` for an omitted `revocation_endpoint_auth_methods_supported`, which does not enforce RFC 8414's default: an empty list means "the metadata said nothing" to `selectClientAuthMethod`, which then honors the registration's own `token_endpoint_auth_method`. The default is named literally now. - The `v8 ignore` on the CLI budget branch was wrong, and the challenge to it was right: an injected `budgetMs` of zero reaches it directly, through a seam I had added myself the round before. Removed, and covered by a test that asserts no request is made and the unattempted key is reported.

fix(auth): salvage a malformed fallback registration, and correct the stale API names (#2144)
Copilot review round 19. - Parsing the preconfigured client registration sat outside the per-slot salvage, so one malformed fallback aborted the whole plan and grants carrying their own valid credentials were never revoked. It is a *fallback*; a bad one is now recorded and skipped, matching every other slot. - `sendPlans` preserved an earlier success when a later key was never attempted, contradicting the failure-first rule two lines below — the unattempted key's grant may still be live. That branch turns out to be a bound rather than a path (`withDeadline` fails any plan that reaches the deadline, so a preceding plan cannot both succeed and leave zero budget), so it carries a justified `v8 ignore` saying exactly that. - `clearStoredAuthForRelogin` takes an optional `budgetMs`, which is what lets the shared-budget behavior be tested without a five-second test. - Three stale references to `planOAuthRevocation`, which no longer exists — two JSDoc links and the `AGENTS.md` entry, which additionally still told callers to make a separate `storage.clear()` call. Following that text would have reintroduced the second clear the atomic step exists to remove.

fix(auth): revoke with the registration bound to the grant, not the current one (#2144)
Copilot review round 17. `resolveClientInformation` mirrored `BaseOAuthClientProvider`, preferring the preregistered entry. That order answers "who should I authenticate as now"; revocation asks "who minted this token", and the two diverge — the store lets a preregistered client and an issuer-bound dynamic registration coexist, so after a server is switched from DCR to a configured `oauth.clientId` an older DCR grant was revoked with the configured client's credentials. RFC 7009 §2.2 answers 200 for a token the server does not recognise as the caller's, so that reported `revoked` while the grant stayed live and the local record was already gone — the worst available outcome. The registration bound to the grant's issuer now wins, with the preregistered entry as the fallback, which covers both directions: a token minted with the configured client leaves the issuer slot empty, since the SDK writes it only after DCR. Stated in the comment rather than implied: this is best available evidence, not proof. The store records client information per issuer, not per token, so binding identity at save time remains the real fix and is a storage-shape change beyond this PR. Also fixed a CLI test comment still describing the pre-round-13 ordering.

fix(auth): refuse a grant whose authorization server cannot be established (#2144)
Copilot review round 15. The issuer check still failed open for the legacy unkeyed grant. "Unkeyed" means its authorization server is UNKNOWN, not that the cached endpoint is proven to own it: server metadata is a single slot a later discovery overwrites, while a pre-SEP-2352 token survives until the first issuer-stamped save. So a clear could post an old bearer credential to an authorization server that never minted it. Such a grant is now cleared without being revoked, and reported as such with a message saying re-authorizing makes future clears revocable. The cost is that a pre-issuer-binding entry gets no revocation — which is exactly the behavior it had before this feature existed, so nothing regresses — and it earns revocation back on the next authorization. Not sending is the only answer that cannot be wrong. Every seed in the suite is now issuer-bound, which is what a real flow writes; the two tests that were about the legacy grant now assert the refusal, since that is the behavior worth pinning. Also renamed the CLI test that still described the pre-round-13 ordering.

fix(auth): key grant dedup by issuer, and isolate per-slot read failures (#2144)
Copilot review round 5. - Deduplicating grants by token string alone could conflate two grants: a token is only meaningful to the authorization server that minted it, so two issuers minting the same opaque value are two grants. The second was dropped before the issuer-mismatch check could report it, and `clear` then deleted it. The key is now issuer+token; the ctx-less read stays suppressed only when its token already came from a slot, which is exactly the active-issuer duplicate and never the legacy one. - A read failure in one issuer slot aborted `collectGrants`, so one corrupt slot left every other revocable grant untouched while the clear deleted them all. Each slot is now read independently and its failure carried as an outcome alongside the grants that could still be revoked; the no-metadata and no-endpoint returns carry them too, so a failure is never swallowed by a skip. - The CLI no longer deduplicates its two key spellings. That could only be done by pre-reading a single token, and `revokeStoredOAuthTokens` now enumerates every issuer slot under a key — so a shared active token skipped the second key entirely, taking any other issuer-bound grant under it with the local delete. A duplicate RFC 7009 request is harmless (§2.2 makes an unknown token a success); a missed one is the leak.

fix(auth): address Copilot review round 2 on the RFC 7009 revocation (#2144)
- `revokeStoredKeys`' pre-read of `getTokens` sat outside the best-effort catch. `getTokens` parses through `OAuthTokensSchema`, so a persisted token that no longer validates rejected and abandoned the local delete `--relogin` promises — over a grant that could not have been revoked anyway. Caught and retained as a failed outcome; the clear proceeds. - The multi-key bookkeeping was wrong twice. A token is now marked spent only on a `revoked` outcome, so a failed or unsupported attempt no longer skips a duplicate entry under the other key that may hold the credentials or metadata that would have worked. And a failure now outranks an earlier success for reporting, so a stale grant left live cannot be hidden behind the first key's 200. - `--no-revoke` is now rejected without `--relogin`, ahead of the short-circuit returns, matching the parser's existing stance on accepted-but-inert flags (`--strict`). On its own it reads as "this run will not revoke anything", true only because nothing was being cleared. - Extracted the App draft merge as `utils/serverWithDraftSettings`, so the rule has a test. The hook tests receive whatever they are handed and cannot tell a draft from a persisted entry, and `App.test.tsx`'s settings harness connects a stdio server where the OAuth section never renders.

fix(auth): address Copilot review round 1 on the RFC 7009 revocation (#2144)
- RFC 8414 §2 defaults an omitted `revocation_endpoint_auth_methods_supported` to `client_secret_basic`; it does not inherit the token endpoint's list. Inheriting made metadata advertising only `client_secret_post` there send POST credentials to an endpoint that never advertised the method. - The 5s timeout was inert on the web paths: `createRemoteFetch` re-issues the call as a POST to `/api/fetch` and drops `init.signal`, and the backend's outbound fetch gets none either, so a wedged AS could hold the teardown open indefinitely. A wall-clock race now enforces the deadline; the signal is kept because it genuinely cancels the direct-fetch paths. - The settings-modal Clear read `settingsModalTarget`, which comes from the persisted `servers` list, while edits live in `settingsDraft` until the save debounce. Toggling the checkbox and clearing immediately used the previous value. It now merges the draft. - `--relogin` clears both key spellings, so it now revokes from both rather than stopping at the first populated one — a stale entry under the other spelling is a live grant. The normalised key goes first, matching `findStoredServerState`, and a second key holding the same token is skipped. - The fixture's /oauth/revoke now ENFORCES RFC 7009 §2.1 client authentication (both RFC 6749 §2.3.1 forms), so the e2e's claim that the Inspector authenticates correctly is actually tested; two negative cases assert a wrong secret and an unidentified client are refused. - Dropped the `as unknown as` casts from the tests: a typed `InspectorLogger` double, and a spy on the real storage instead of a spread-and-cast. - Added CLI-level tests through `runCli` for `--no-revoke`, the per-server `oauth.revokeOnClear`, and the stderr warning, and TUI tests for the forwarded opt-out and the rendered failure.

fix(auth): cover the CLI refresh path and tighten the well-known match
Two review findings. The stored-token refresh path (`refreshStoredAuthToken`) calls SDK discovery directly rather than through `InspectorClient.effectiveAuthFetch`, so a state file holding a refresh token and client information but no `serverMetadata` still hit the upstream OIDC-schema failure and could not refresh against the very servers this change is for. Its default `discover` now wraps the global fetch with the compat shim; a caller-supplied `fetchFn` is left alone. Covered by a test that injects no `discover` — injecting one would bypass the default under test — against a real server that 404s the RFC 8414 path and serves plain RFC 8414 metadata at the appended OIDC path. `oidcDiscoveryCandidates` matched the well-known path by bare prefix, so it also claimed `/.well-known/oauth-authorization-server-backup` and would have replaced that path's failed response with a document fetched from a derived URL. It now requires the exact path or a `/` boundary, which is precisely the set `buildDiscoveryUrls` can emit.

feat(auth): revoke OAuth tokens at the authorization server on clear (#2144)
Clearing the Inspector's OAuth state deleted the local copy of the tokens and stopped there. The access token — and the refresh token, which is long-lived by design — stayed valid at the authorization server until they expired on their own, so a day of connect/disconnect iteration left it holding grants for sessions that ended hours ago. RFC 7009 §1 describes exactly that case, and nothing in the repo constructed a revocation request, so a server author implementing `revocation_endpoint` had no way to exercise it with the tool that exists to exercise this. core/auth/revocation.ts builds and sends the request; the three clear paths call it, so the behavior is written once — web's "Clear OAuth state and disconnect" (both the active and stored-only paths), the TUI's Auth tab, and the CLI's --relogin. It runs BEFORE the local clear, because the token, the client credentials and the discovered `revocation_endpoint` all live in the store the clear is about to empty. The request names the refresh token when there is one: §2.1 asks the AS to also invalidate the access tokens issued under the same grant, so one request covers both halves. Best-effort by construction. Every path returns a TokenRevocationOutcome rather than throwing: no advertised endpoint means nothing is sent and that authorization server behaves exactly as before, and a network error, a non-2xx, a 5s timeout or an unreadable store is reported and nothing more. Forgetting the tokens is what the user asked for. `lost_authorization_state` recovery deliberately skips it — it clears a half-finished flow to retry it, and an authorization that never completed has no grant to revoke. Client authentication resolves the preregistered slot first, mirroring BaseOAuthClientProvider.clientInformation; reading only the dynamic slot would send no authentication for a server configured with `oauth.clientId`. The Basic credential is byte-identical to the SDK's applyBasicAuth so this request and the token request cannot present the same secret differently. Opt out per server with `oauth.revokeOnClear` (default on, only `false` written to disk) or per CLI run with --no-revoke. Read at clear time rather than connect time, so toggling needs no reconnect. Turning it off is a testing affordance: a client that walks away still holding live tokens is a case a server author may want to reproduce. test-servers now advertises `revocation_endpoint` and serves POST /oauth/revoke, faithful on §2.2 (an unknown token is a success) and §2.1 (revoking a refresh token invalidates the access tokens under the same grant), with oauth-revocation-http.json / oauth-no-revocation-http.json as showcase configs.

fix(oauth): walk the candidates in the CLI refresh path too
Copilot review round 1. `refreshStoredAuthToken` consumes the same fallback and made a single SDK discovery call, so preserving the path there — without the walk the other two consumers got — would have regressed exactly the case the walk exists to keep: a path-hosted MCP server whose authorization metadata is published at the domain root. It injects its own discovery function as a test seam, so the walk is now also exposed as `discoverAuthorizationServerMetadataFromCandidates(candidates, discover)`, which takes that function and reports *which* candidate answered — the CLI needs the winning URL, since it is the base the token request is made against, not just the metadata. Also drops the `as unknown as typeof fetch` from the new test in favour of `vi.fn<typeof fetch>()`.

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

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

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.

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.

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

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.

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.

fix(cli): apply a server's persisted mcp.json metadata
The web client and the TUI both read `savedSettings.metadata` and pass it
as `InspectorClientOptions.defaultMetadata`. The CLI never did, and
`InspectorClient` only reads the option rather than falling back to
`serverSettings.metadata` — so a per-server `metadata` entry was silently
inert for `--cli` runs.
Pass it beside the existing `roots:`, guarded on a non-empty map the same
way web and the TUI guard theirs, so `{}` still means "no defaults".
Precedence is unchanged: call-time keys override defaults in `mergeMeta`,
so `--metadata` stays per-invocation and wins on a key collision.
Covered by three catalog-driven tests asserting against the test server's
recorded wire requests. `createTestConfig` is retyped `StoredMCPServer` —
the accurate on-disk shape — since a fixture that cannot express the
per-server keys cannot cover the settings that reach the client.
Closes #2093

fix(web): move the app origin off 6276, bound the publish route
Copilot review round 2 on #2100, plus a collision the review did not find. The default app-origin port was 6276 — which is already RUNNER_OAUTH_CALLBACK_DEFAULT_PORT, the CLI/TUI loopback OAuth callback. That port is fixed precisely so an OAuth app can pre-register http://127.0.0.1:6276/oauth/callback, which makes it the one listener here that cannot move when something takes it first. A running --web would hold it and break a later --cli/--tui OAuth flow at its registered redirect URI, and docs/mcp-app-review.md has those two running side by side. This listener has a documented dynamic fallback, so this listener yields: the default is now 6278 (6277 skipped — v1's retired proxy port, which the migration guide tells people to stop forwarding). A test asserts the two defaults stay distinct. Review comments: - POST /api/app-document now applies hono's bodyLimit BEFORE parsing. The 8MiB check ran after c.req.json() had buffered and parsed the whole request, and bounded only `html` — so bulk in `csp`, or in keys the route never reads, was fully materialized before the 413. - `csp` is validated as an HTTP header value and length-bounded. The controller hands it to res.writeHead() verbatim, where Node throws ERR_INVALID_CHAR synchronously — inside the handler for a later, unrelated request, outside this route's error handling. - The app-origin port now propagates everywhere the other two do: the CLI --print-handoff port-forward command (and its test), the Dockerfile's ENV and EXPOSE, and the remote-review SSH recipe in docs/mcp-app-review.md. Without it an app declaring _meta.ui.domain is unreachable through every documented remote workflow.

test(proxy): isolate proxy env per file; word the guard failure by candidate source
Addresses review round 7 on #2099 (three suppressed comments). - Proxy variables are now cleared for the WHOLE of `transport.test.ts` and `cli.test.ts`, not just around the proxy tests. Measured: undici's `EnvHttpProxyAgent` captures its proxy URLs when it is CONSTRUCTED and re-reads only NO_PROXY per request, so with the process-wide memo, any earlier test that connects on a machine with an ambient proxy would pin the agent to it and a later test setting HTTP_PROXY would be talking to an agent that is not listening. Clearing up front means nothing can build the singleton before the proxy tests do, and restoring only in the file-level afterAll means the memo cannot be left bound to a closed test proxy. Both suites verified green under a hostile ambient env (`HTTP_PROXY`/`http_proxy`/`HTTPS_PROXY` pointed at a dead port). In fairness this is hardening rather than a fixed failure: the concrete cross-test break did not reproduce with the current test order — but it depends on test order and on the developer's environment, which is exactly what this removes. - The guard's failure message said a package "is declared external but was inlined" even for a candidate that came only from the root dependencies — i.e. #2067's own shape, where the missing `external` entry IS the bug, so the message contradicted the config it was asking the reader to check. It now words the failure by candidate source, and says to add the entry. The capture-at-construction behavior is documented on `createProxyFetch`, since it is the reason the suites are structured this way.

test(proxy): cover the CLI and TUI bottom-of-stack wiring
Addresses review round 5 on #2099 (three suppressed comments, no posted ones). The `fetch: createProxyFetch()` line in each Node client is the whole of that client's proxy support — it is what puts the proxy at the BOTTOM of the fetch stack, where InspectorClient's wrappers compose over it rather than discarding it. `InspectorClient` sets `fetchFn` unconditionally, so the transport-level fallback never fires for these clients. Both lines could have been deleted with every existing test still green. - CLI: a test that runs a real `tools/list` against a real HTTP test server with HTTP_PROXY pointed at a real forwarding proxy, asserting the request traversed it. Behavioral rather than structural on purpose — the defect this replaces was a runtime dispatch failure no structural assertion would have caught. It clears all six proxy vars first so an ambient value cannot route it elsewhere. - TUI: the mock added earlier always returned undefined, so the proxy branch was never exercised. `createProxyFetch`'s return is now controllable, and two tests assert the sentinel reaches `environment.fetch` when a proxy is configured and that the slot stays unset when one is not. Both were confirmed to fail with their client's wiring line removed. Also updates the `InspectorClientEnvironment.fetch` doc in core/mcp/types.ts, which still told callers that Node leaves this undefined and uses the global fetch.

fix: stop leaking metadata values into diagnostics, and salvage per key
Two credential leaks, the same class already fixed for the client logger: `serverList` printed the malformed entry verbatim — a legacy row missing `key` still holds whatever the user configured — and the CLI overflow error echoed the whole `key=value` pair into stderr and CI logs. Both now name the key and the offending *type*; a test plants a `sk-live-…` and asserts it appears nowhere while the key still does. `normalizeStoredMetadata` now also drops a value that parses but cannot be sent. A hand-edited catalog is the reachable source: it is parsed server-side, so `1e400` really does become `Infinity` there, and the next write would store `null`. Filtered per key, matching the per-item salvage this file already does elsewhere, so one bad value does not cost the user the rest. Deliberately *not* added to the `/api/servers` guard, which review also suggested. Writing that test is what showed why: a client's own `JSON.stringify` turns `Infinity` into `null` before the request is sent, so the wire cannot carry the bad case at all — and the check made things worse, rejecting the whole metadata field where the normalizer drops one key. The guard stays a container check, with a comment recording both points.

fix: reject non-finite numbers before they reach _meta
`StrictJsonValue` removed `undefined`, but the type cannot express the rest of
the gap: TypeScript has one `number`, and JSON has no encoding for `NaN` or
`±Infinity`, so `JSON.stringify` rewrites them to `null`.
This is reachable from ordinary input, not a careless caller.
`JSON.parse('{"a":1e400}')` returns `Infinity` on overflow — so text a user
types parses cleanly, satisfies the type, and reaches the server as `null`
while the editor still shows `1e400`.
`isSerializableJson` in `core/json` is the runtime half of `StrictJsonValue`,
applied at both boundaries that turn text into metadata:
- the editor's draft parser, which now reports "Numbers must be finite" inline
and withholds the value rather than emitting one it cannot send;
- the CLI's `--metadata` / `--tool-metadata` parser, which throws. Silently
sending `null` would be wrong, and so would falling back to the literal
string — neither is what was asked for.
Tests cover the validator directly (including that `JSON.stringify` really does
write `null`, which is the reason it matters), the editor parser, and the CLI
flag.

fix: redact secrets nested inside metadata in servers/show
The redaction checked only top-level keys. That was sufficient while values were strings — a secret could not hide beneath one — but #1910 lets a value be an object, so `{ trace: { accessToken: "…" } }` printed in full: `trace` is not sensitive, so the whole subtree went out with it. `servers/show` output is meant to be safe to paste into an issue, so this is a regression this PR introduced rather than a pre-existing gap. `redactMetadataValue` walks the payload: a key matching `isSensitiveHeader` replaces its entire value (so a sensitive key holding an object cannot leak through its members either), anything else is descended into, and arrays are mapped elementwise since objects inside them can carry sensitive keys. Recursion is bounded — the payload came from `JSON.parse`, so it is a finite tree with no cycles. Tests cover a secret two levels under a non-sensitive key and one inside an array element.

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.

test(cli,tui): typecheck the __tests__ dirs (#1791) (#1799)
* test(cli,tui): typecheck the __tests__ dirs (#1791) The cli/tui `typecheck` scripts only checked `src` (the src-only tsconfig excludes `**/*.test.*`), leaving the `__tests__` dirs — which do the most `as` casting — with no tsc pass. Add a `tsconfig.test.json` per client that includes `__tests__` with the test-exclusions dropped and the test-only path aliases (`@modelcontextprotocol/inspector-test-server`, the `@inspector/core/*` deep paths, express/vitest) resolving what vitest resolves, then fold `tsc -p tsconfig.test.json` into each `typecheck`. Fixes the 76 errors it surfaced: - cli: a wrong `@modelcontextprotocol/inspector-core/...` module specifier (should be `@inspector/core/...`; only a type import so vitest never caught it), `r.headers` optional-access guards, and partial OAuth mocks replaced with typed `makeFakeCliOAuthClient()` / `makeFakeServerSettings()` factories instead of `as` casts. Adds `@types/express` (devDep) so the transitively aliased test-server source typechecks, mirroring clients/web. - tui: rest-param signatures on the App OAuth spies (fixes the spread-arg and narrow-return errors), a widened callback param (`iss?`), a `makeFakeServer- Settings()` factory for the tuiOAuth tests, required OAuth-metadata/client fields in AuthTab, and a loosened `entry()` message param for the deliberately-malformed wire messages HistoryTab's defensive branches render. Gate coverage only; no runtime behavior change.

Completes the "every client's __tests__ is typechecked" invariant. - Doc the new test-typecheck + config-file typecheck in AGENTS.md.

Now typechecked. - App.test.tsx: type `callTool` against `InspectorClient["callTool"]` (+ the Parameters<…> wrapper) so its `mockResolvedValue` payloads are checked, and give `clearOAuthTokens` an `async () => {}` impl so the mock actually returns the `Promise<void>` its type promises. - AGENTS.md: correct the per-client alias-set description (cli's is widest, tui's is core+react only, launcher's has no paths) and note launcher's config file lives in its test project, not the src project.

This closes the class the review kept surfacing by hand (launcher/__tests__ in round 3, launcher/vitest.config.ts in round 4) — a new top-level file can no longer go untypechecked silently. Wired into `npm run ci` and the GitHub workflow. - launcher: reorder `validate` to run `typecheck` before `build` (matches tui and the documented order), and make `typecheck` self-contained — it now runs both `tsconfig.json` and `tsconfig.test.json`, so running it standalone means the same thing it does in cli/tui. - makeFakeCliOAuthClient: note on the comment that the typing covers the defaults, not `overrides` (a bare vi.fn() override is Mock<(...args)=>any>). - Docs: README table + AGENTS.md updated for the new guard and the corrected launcher typecheck/validate ordering.

Verified: stripping `npm run typecheck` from launcher's validate now fails the guard. - Nit 3: switch `tsc --listFiles` → `tsc --listFilesOnly` (identical file list, ~4× faster: whole guard 23s → ~4s). Now cheap enough for the inner loop, so it moves into `validate` (right after verify:format-coverage) instead of a standalone ci step — matching its sibling. Removed the separate ci-chain entry and GitHub workflow step (validate covers it). - Nit 4: `npx --no-install tsc` so a missing local tsc fails fast instead of reaching for the registry (matches verify-build-gate.mjs). - Nit 5: corrected projectFiles' JSDoc to describe the filter that's actually there (drops repo-external + node_modules paths; core/ + test-servers/ stay but are harmless). - Finding 2: fixed the 2-space misindent on the new root package.json line (prettier --write). Docs (README/AGENTS) updated for the validate placement.

Also accepts `--project`. - Nit 3: on a tsc config error, echo the `error TS…` diagnostic (scanning both streams — tsc prints config errors to stdout) so a broken tsconfig is self-explaining rather than surfacing only as a misleading "file in no project" report. - Nit 4: refreshed the CI workflow's stale "Validate" step name/comment (it now runs the coverage guards + validate:core + per-client typecheck). - Nit 5: reworded the `.d.ts` carve-out comment to read as pre-emptive (there are none under cli/tui/launcher today).

No-op on today's tree (no client `.mts`/`.cts`); confirmed a tracked `.mts` with a type error is now caught. Ambient `.d.{ts,mts,cts}` stay excluded. - Nit 2: drop the unused `export` on `rootReachedCommands` (internal to the lib; nothing imports it, and scripts/ isn't eslint-gated to catch dead exports). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * test: round-8 — single casts in HistoryTab, uniform wrappers, doc scope Responds to the round-8 @claude review of #1799: - Finding 1: reduce the `MALFORMED` helper and `entry()`'s return cast from `as unknown as` to a single `as` (both compile clean — the malformed shapes are comparable to the JSONRPCMessage union), and delete the false "only option" sentence. Fixes the AGENTS.md avoid-double-casts violation. - Nit 3: write all seven FakeClient OAuth wrappers as `(...a: Parameters<InspectorClient["…"]>)` (the three zero-arg ones were hand-written `()` forwarders), so the block comment's "forward the same Parameters<…> tuple" is literally true and a future added parameter can't be silently dropped. - Nit 2: update the five places that still described the guard as `.ts`/`.tsx` only to `.ts`/`.tsx`/`.mts`/`.cts` (script header + trackedSourceFiles JSDoc, AGENTS.md ×2, README.md). Nits 4 (js config files out of the typecheck guard by construction) and the footnoted callTool/ancestor-tsc items left as agreed.

It was unnecessary (the spread of Partial<MessageEntry> over complete defaults is directly assignable) and harmful — it silenced type errors in the helper's OWN default fields (a `direction`/`method` typo now surfaces TS2820/TS2353). MALFORMED's single cast stays (load-bearing). This leaves MALFORMED as the file's only cast, matching what the comments describe. - Nit 2: add `rootReachesScript` to scripts/lib/npm-scripts.mjs and have each coverage guard assert its SIBLING is still wired into the root `validate`. A guard can't detect being unrun itself, but the two now vouch for each other, so dropping either from `validate` is caught by the other (only deleting both slips through). Verified: removing verify:typecheck-coverage from validate now fails verify:format-coverage, and vice-versa. Nits 3 (git-index visibility) and 4 (pre-existing as-never/as-unknown casts in tests — out of scope, none added by this PR) left as agreed.

(Splits each script on `&&`/`||`/`;` so a flag on one command can't taint another.) Verified a `typecheck` using `tsc … --noCheck` now fails with a clear message; `--noCheck` is a live idiom here (cli's test-servers:build), so this is a real copy-paste hazard. - Nit 2: reachableScripts (shared lib) now also follows npm's implicit `pre<name>`/`post<name>` lifecycle hooks, so moving a gate into e.g. `prevalidate` is recognized instead of producing a false "not reachable" failure (cli already uses a `pretest` hook). Verified. - Nit 3: AGENTS.md "Test placement" now states the Node clients (cli/tui/ launcher) keep all tests in `__tests__/`, enforced by verify:typecheck-coverage (a co-located src test lands in no tsconfig project). - Nit 4: noted on the factory comments that `Partial<…>` overrides admit an explicit `undefined` for a required field (exactOptionalPropertyTypes off). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * fix: round-11 — launcher build excludes tests; guard catches all noCheck vectors Responds to the round-11 @claude review of #1799: - Finding 1 (shipping bug): clients/launcher/tsconfig.json now excludes `**/*.test.{ts,tsx}` (matching cli/tui). launcher's `build` is an EMITTING tsc over src/**, and clients/launcher/build is in the root `files` allowlist, so a co-located `src/**/*.test.ts` would have been compiled into the published tarball. Excluding it also makes such a test land in no tsconfig project, so verify:typecheck-coverage catches it — making the AGENTS.md placement rule literally true for all three clients. - Finding 2: verify-typecheck-coverage now catches both remaining ways a typecheck could check nothing: (a) case-insensitive `--noCheck`/`--nocheck`/ `--listFilesOnly` on the command, and (b) `noCheck` set in the tsconfig itself (detected via `tsc --showConfig`, which surfaces it from the config or its extends chain). Verified both fail the guard. - Nits 3 & 4: restructured into an explicit gate-integrity phase (wiring + neutered + config-noCheck + no-projects) that reports under its own accurate header and exits BEFORE the file-coverage pass — so an inert gate no longer prints file-remediation advice, nor buries the real cause under an "in no tsconfig project" line for every file that gate covered. The one CIMD OAuth E2E integration test that flaked in the coverage run passes 32/32 in isolation and on re-run; unrelated to these script/config changes.

All three clients now exclude `**/*.test.*` (one glob, covering .ts/.tsx/.mts/.cts) — which is also exactly what AGENTS.md already claims. Verified a `src/probe.test.mts` is no longer emitted and now fails the guard. - Finding 2: the gate-integrity phase no longer prints a false "names no `-p <project>`" line when config-`noCheck` disables projects — the condition now keys off `projects.length` (harvested), not `checking.length` (post- filter), so a client whose projects were all config-disabled shows only the accurate per-project lines. - Nit 3: recorded the boundary on the phase comment — it does not detect shell-level failure suppression (`… || true`, `; exit 0`). - Nit 5: the file-coverage remediation now leads with "for a co-located test, move it to `__tests__/`" (adding it to the src `include` would reintroduce the build emit) before the general add-to-include advice.

Also harvests `-b`/`--build` project paths. Verified `tsc --noEmit && tsc --noEmit -p tsconfig.test.json` now reports OK. - Finding 2: CLIENTS is no longer hardcoded — it's derived from the `cd clients/<x> && npm run validate` entries in the root `validate` chain (minus an explicit web exclusion), so a new Node client is auto-required, matching the repo-wide reach of its sibling verify-format-coverage. Added a guard-would-check-nothing bail if the derivation yields an empty set. Verified a new `clients/newclient` is picked up and its uncovered file flagged. - Nit 3: the phase-2 remediation now leads with the general add-to-`include` advice and only appends the "move it to __tests__/" note when a failing path is actually a test file (was misdirecting plain files). - Nit 4: AGENTS.md no longer says the test config includes "only" __tests__ (launcher's also includes its vitest.config.ts). (Two different web integration tests each flaked once under parallel load during the coverage runs — both pass in isolation and on a clean re-run; timing- sensitive and unrelated to these script/doc-only changes.)

The chain derivation was fail-open: a root-chain edit that kept running a client but didn't match the strict regex silently dropped it from the required set (112→53 files, still green). Disk is fail-closed — a client can't be silently dropped, a new client with a typecheck is auto-required, and web (no typecheck script; builds via `tsc -b`) is excluded on its own, so the explicit exclusion is gone. The existing `rootRunsClientValidate` wiring check still verifies the root chain runs each — now LOUD when it doesn't. Verified: `cd ./clients/tui && …` now hard-fails the integrity phase instead of silently shrinking coverage; `cd clients/tui && npm run build && npm run validate` stays gated. Removed the now-unused `clientsRunByRootValidate` from the shared lib. - Nits 2 & 3: documented the two unreachable-today limitations on typecheckProjects — a solution-style `tsc -b` (empty `files` + `references`) would under-report, and the implicit-tsconfig fallback assumes no file operands. - Nit 4: refreshed the file header to mention `-b`/`--build` + the implicit `./tsconfig.json` (only the JSDoc had been updated).

Now every `clients/*` with a readable package.json must EITHER declare a `typecheck` (→ enrolled) OR be in an explicit EXEMPT map (`clients/web`, reason: `tsc -b`); anything else is a hard gate-integrity failure. This is fail-closed on the rename axis too, and web's skip is a stated decision rather than an accident of which scripts it declares — so web gaining a `typecheck` no longer auto-enrolls it into the solution-`-b` false failures. Verified: renaming tui's `typecheck` now hard-fails; a `tsc -b` on web stays exempt. - Nit 3: `rootRunsClientValidate` normalizes a leading `./`, so `cd ./clients/tui && npm run validate` (which genuinely runs it) is no longer a false "no longer runs" alarm. - Nit 2: README/AGENTS/script-header prose no longer names a fixed cli/tui/launcher scope — they describe the disk-discovered "every clients/* with a typecheck script (web exempt)" rule.

Now an anchored regex (escaped dir + optional leading `./` + a trailing boundary). Verified the sibling case now hard-fails. - Nit 2: a `clients/*` dir holding tracked TS but no readable package.json is now a gate-integrity failure (was treated as "not a client"), so the "fail-closed on every axis" claim holds. Verified. - Nit 3: readdirSync is wrapped, so a missing `clients/` dir yields the intended "found no clients/* dir" message rather than a raw ENOENT stack. - Nit 4: EXEMPT's reason is now surfaced in the success line ("clients/web exempt: typechecks via tsc -b …"), so the exemption is visible at runtime, not only in source. (Also moved `isRequiredSource` above nodeClients — nit 2's new tracked-TS check calls trackedSourceFiles at module-init, which referenced it before init.)

So a quoted `-p "tsconfig.test.json"` (a form tsc accepts) made the typecheck guard report every file that project covers as uncovered, and a quoted `cd "clients/tui"` in the root chain tripped a false wiring failure. Moved tokenize() (now single+double quote) into the shared lib, imported it into both guards, rewrote typecheckProjects to walk tokens (`-p`/`--project`/`-b`/`--build` → next token), and strip quotes before the `cd` match in rootRunsClientValidate. Verified both quoted forms now pass. - Nit 2: a stale EXEMPT key (a dir that no longer exists) was asserted in the success line unchecked. nodeClients now fails if an EXEMPT key isn't a real `clients/*` directory. Verified. - Nit 3 (build/dist filter belt-and-braces) left as a recorded boundary.

Now matches on the token basename (`isTsc`), keeping round-17's quoting fix while restoring the tolerance. Verified a `node_modules/.bin/tsc` typecheck reports OK. - Nit 2: `rootRunsClientValidate` stripped quotes for the `cd` match but tested `npm run validate` against the unstripped string, so `npm run "validate"` false-failed. Both halves now test the stripped string. - Nits 3 & 4: documented on typecheckProjects — the contrived `--noCheck false` (checking on) is still treated as disabling, and the `&&`/`||`/`;` split runs before tokenizing (a quoted operator inside an arg would split mid-token, unreachable for project paths).

Added it explicitly to `clients/cli/tsconfig.test.json`'s include (zero source changes; verified a bad line in it now fails cli's typecheck). Softened the AGENTS.md clause that implied the whole test-server source is transitively covered. - Nit 2: `rootRunsClientValidate` now also recognizes the `npm --prefix <dir> run validate` invocation form (was `cd`-only). - Nit 3 (stderr spy drops the completion-callback overload): left as-is — latent, not live (no exercised path awaits a stderr drain), and adding typed overload params would reintroduce the write-overload complexity the round-1 vi.spyOn refactor removed.

So the root chain could run a client's `validate:fast` while the guard kept measuring its `validate` (unrun), green. Anchored the tail to a boundary (`/\brun validate(?=$|[\s&;])/`). Verified `validate:fast` now hard-fails. - Finding 2: durably close the test-servers/src class instead of point-fixing. Added a SHARED_ROOTS check — every tracked TS under `test-servers/src` + the root `vitest.shared.mts` (the `format:check:shared`/`lint:shared` surface) must land in the GLOBAL union of client projects. So a NEW unimported bin entry is caught (not just server-composable.ts, named in round 19). Verified a fresh `server-orphan-bin.ts` now fails. Zero source changes — the union already covers 15/15. - Nit 4: the integrity message and rootRunsClientValidate docstring now mention the `npm --prefix` form too.

This closes BOTH round-21 findings at once: - Finding 1 (stale allowlist fail-open): a rename of `test-servers/src` no longer silently drops it — its files reappear in the required "other" set and hard-fail (verified: `git mv test-servers/src test-servers/source` now fails instead of going 127→113 green). The subtractive `core/` exemption is fail-closed on staleness for the same reason. - Finding 2 (allowlist vs deny-by-default): a new top-level TS location is now auto-required (verified `tools/probe.ts` is flagged), matching the repo-wide reach of the sibling verify-format-coverage. - Nit 3: added the shared-source clause to the README table row (AGENTS got it last round). Header comment updated to describe the non-client coverage.

So a `core/*.tsx`/`*.mts`/`*.cts` or a co-located `core` test got no tsc pass from anything. Narrowed the exemption to exactly that shape (`isExemptCoreFile`): a core `.ts` that isn't a co-located test. So a core `.tsx`/`.mts`/co-located test is now required in some project. Zero-fix today (0 such files); verified `core/mcp/probe-widget.tsx` and a co-located core `.test.ts` are now flagged. - Nit 2: `EXEMPT_ROOTS` is now a Map (dir → reason) and its reason is surfaced in the success line alongside the client exemption. - Nit 3: the non-client miss message is now the general "in no client's tsconfig project"; the `test-servers` remediation clause is conditional on an actual `test-servers/` path (tracked via `nonClientMisses`, not string-sniffing the composed message). - Nit 4: success line says "(N clients + non-client)".

So a `core/**/__tests__/*.test.ts` (a live layout — `core/mcp/__tests__/fakeInspectorClient.ts` already sits there) was flagged though web checks it. Now mirrors the UNION: under `__tests__/` → exempt `.ts`/`.tsx`; otherwise `.ts` minus co-located `*.test.ts(x)`. Verified a core `__tests__` test now passes while a core `.tsx` outside `__tests__` stays required. - Finding 2: `EXEMPT_ROOTS` was a Map whose keys nothing read (round 22 replaced its filter with hardcoded `isExemptCoreFile`) — a phantom registry. Collapsed to a single `CORE_EXEMPT_REASON` const used in the OK line. - Nit 3: README/AGENTS scope descriptions updated (core is no longer wholesale excluded; the non-client set is deny-by-default).

This was the last whole-tree exemption wider than the gate it defers to. Now web is ENROLLED: a client with no `typecheck` script but a `tsconfig.json` `references` array is measured through those reference projects (`tsc -p <ref> --listFilesOnly`), and is wired iff its `validate` runs `tsc -b` (`validateRunsTscBuild`). EXEMPT is now the empty escape hatch. Verified: a web-root `playwright.config.ts` with a type error is now flagged, and dropping `tsc -b` from web's build hard-fails the integrity phase. Zero-fix on the tree — the union of web's 4 projects covers all 625 tracked web files. - Nit 2: assert `core/` exists (the OK line unconditionally states its exemption) — parity with the EXEMPT stale-key check. - Nit 3: a `core/` miss now gets core-specific remediation (widen web's `tsconfig.app.json` include, not a cli/tui project). - Nit 4: README/AGENTS scope descriptions corrected — web is enrolled (not exempt), and the exact core-exempt shape (app `*.ts` minus co-located tests + test `__tests__/**/*.{ts,tsx}`).

Deleted `isExemptCoreFile`, `CORE_EXEMPT_REASON`, the core presence assertion, and the exemptNote core clause. `core/` is now required like everything else and covered by measurement (127→894 files; a `core/*.tsx` web doesn't reach is now caught by measurement, not a hand-model). Kept the core-specific remediation clause. - Finding 2: the reference (`tsc -b`) path skipped the non-inertness check — a `tsc -b --noCheck` build gated nothing while the guard stayed green. Turned `validateRunsTscBuild` into `tscBuildStatus` (ok/neutered/none); a neutered `tsc -b` now hard-fails, matching the typecheck-script path. Factored the disabling-flag predicate (`isDisablingFlag`) so both paths share it. - Nit 3: `clientTsconfigReferences` now strips block comments too (every other tsconfig in the repo uses `/* */`). - Nit 5: README/AGENTS wiring clause covers web's `tsc -b` (not just the `typecheck` script), and core is described as measured, not exempt. Nit 4 resolves itself: EXEMPT is empty and the exemptNote/ternary now collapse cleanly. Nit 6 (tsc -b bound to a specific tsconfig) left as recorded.

Fixed at the measurement layer: projectFiles now expands a solution config (`{"files":[], "references":[…]}` — lists nothing under --listFilesOnly) to its references and measures those recursively, so a `tsc -b` project is measured no matter which path harvests it. Generalized the references reader (tsconfigReferences(path)). Verified web with `typecheck: "tsc -b"` now passes. Dropped the stale "web … is out of scope" JSDoc clause. - Nit 2: a `core/**/__tests__/**` miss now points at `tsconfig.test.json` (its actual owner), not `tsconfig.app.json`. - Nit 4: AGENTS.md's one-line summary now mentions the non-client (`core/`, `test-servers/src`) coverage, matching the detailed bullet. Nit 3 (EXEMPT empty, dormant stale-key check) left as the intended escape hatch.

Factored a shared `resolveLeafProjects` (a solution → its real leaf projects, cached rawProjectFiles) used by BOTH coverage (`projectFiles`) and a shared `checkingLeaves` disable-check, so a `noCheck` in a referenced project is now caught on either path. Verified: `typecheck: "tsc -b"` + `noCheck` in tsconfig.app.json now hard-fails (was green). Caching also cut the guard from ~20s to ~11s. - Nit 2: directory-form references (`{ "path": "./packages/a" }`) now resolve to `<dir>/tsconfig.json`, so a nested-solution dir reference is expanded. - Nit 3: reworded the empty-listFiles comment (it's "solution config OR errored config", both of which the reference expansion handles). - Nit 4: script header notes a `tsc -b` solution is reduced to its references on either enrollment path.

Now tracks visited leaves in a Set and skips an already-seen leaf entirely. Verified a duplicate harvested project yields one line, not two. - Nit 3 (record-completeness): noted in AGENTS that the one tier the guard structurally can't see — a per-file `// @ts-nocheck` — is owned by `@typescript-eslint/ban-ts-comment` across lint:core/lint:shared/each client. Nit 2 (the ~11s perf claim isn't reproducible on a CI-class runner) and nit 4 (hybrid-solution / composite boundaries, both tsc-rejected → unreachable) left as recorded.

Behavior when run directly is unchanged (894 files). - Added table-driven tests (node's built-in `node --test`; the root has no vitest harness by design) for the shared lib (`tokenize`, `reachableScripts` incl. pre/post hooks, `rootRunsClientValidate` across cd/--prefix/quoted/ prefix-sibling/`validate:fast`, `rootReachesScript`) and the guard's parsers (`isRequiredSource`, `isTsc`, `isDisablingFlag`, `typecheckProjects`, `tscBuildStatus`) — one case per rule a review round found (r7/r10/r13/r15/ r16/r17/r18/r19/r20/r25). 12 tests. Wired `test:scripts` into `validate`. - Nit 2: a `scripts/*.ts` miss now gets a scripts-specific remediation (keep it `.mjs`, or give `scripts/` its own tsconfig project). - Documented the guard's test suite in AGENTS.md.

So dropping it from validate, or renaming a test to `*.spec.mjs`/`*.test.mts` (which node --test silently skips), now hard-fails. Verified both. - Nit 2: extracted a pure `parseTsconfigReferences(raw)` from tsconfigReferences and table-tested the JSONC tolerance (block/line comments, trailing comma, no references, malformed, no path) — the r17/r26 rules had no cover. - Nit 3: added `-b`/`--build`/bare-`tsc -b` and explicit `--project` cases to typecheckProjects's test so its title matches its table. - Nit 4: rewrote the rootRunsClientValidate test to put `cmd` in a script reached from validate, and added the reachability cases (an orphan cd-validate must NOT count; validate:tui indirection must) — the r5 property. - Nit 5: added test:scripts to AGENTS's validate ordering + the README table. 15 guard tests now.

The glob half read `rootPkg.scripts["test:scripts"]` literally while the wiring half two lines above used `reachableScripts`, so a delegating `test:scripts` (`npm run test:scripts:lib && npm run test:scripts:guard`) — which genuinely runs all 15 tests — reported every tracked test file as "not matched by the glob", advising a rename the files already satisfy. Now harvested across every script reachable FROM `test:scripts`, the same fix round 6 applied to the `typecheck` harvest; `pretest:scripts` counts for free. 2. `globToRegExp` escaped `{`/`}` as literals and left `?` as a regex quantifier, both divergent from `node --test`'s glob. `*.{test,spec}.mjs` is the natural widening here (the guard's own file scan already treats a `.spec.` file as a test) and false-failed; `?` silently meant "optional previous char" and threw outright when segment-leading. Adds `?` → `[^/]` and a brace-alternation pass, with an unbalanced brace falling back to a literal. Nit 3: `resolveLeafProjects`'s two path-resolution rules (the r26 directory-form reference, and refs resolving against the referring config's dir) extracted as `projectConfigFile`/`refToProject` so they are one-row tables like the other parsers, rather than untestable behind a `tsc` spawn. Nit 4: AGENTS.md + README document that the guard now enforces `test:scripts` on three axes (wired, non-empty, glob-covered). Verified: probes C and D exit 0; probe B (rename to `*.spec.mjs`) still caught; `test:scripts` 18/18; `verify:typecheck-coverage` OK 894 files; `verify:format-coverage` OK 919; `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-32 — measure globs with node's own matcher Round-32 review; both findings point at deleting code. 1. `globToRegExp` hand-modeled `node --test`'s glob and was still one form short — character classes (`*[.]test.mjs`, `*.test.[mc]js`) hit the escape set and became literals, so the guard false-failed on files node genuinely runs. Replaced the whole translator (and its brace balance pre-scan) with node's `path.matchesGlob` — 22.5.0+, and the repo floor is >=22.19.0. Same *measure, don't model* move round 25 made when it deleted `isExemptCoreFile` in favor of measuring web's projects; being exact for every form node accepts is the point, since node's matcher is the thing being modeled. 2. The round-31 glob harvest was inline in `main()`, so mutation-reverting it to the literal single-script read left the suite green — the commit's headline fix was its one untested change. Extracted as `testScriptGlobs`, with rows for the direct form, the delegating form (both child globs, not `npm`/`run`/`<name>`), a `pretest:scripts` hook, and an unreachable script contributing nothing. Nit 3: `resolveLeafProjects`' JSDoc moved back onto it (the extraction left it stranded above `projectConfigFile`, which had two stacked doc blocks). Nit 4a: a `test:scripts` naming no path/glob harvested nothing, and `.some()` over an empty list blamed every test file with unfollowable advice. Now one explicit message naming the real problem. Verified: probes for the direct, delegating, brace, `[.]` and `[mc]` forms all exit 0 (the last two were false failures before); probe B (rename to `*.spec.mjs`) still caught; bare `node --test` reports the new single message; `test:scripts` 18/18; `verify:typecheck-coverage` OK 894; `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-33 — scope the glob harvest to `node --test` segments 1. False pass. `testScriptGlobs` kept every non-flag token from every reachable script, so a glob belonging to a NEIGHBOURING command was attributed to the test runner — and since `.some()` needs only one glob to match, a broader one suppressed a real miss rather than adding an inert pattern. A `pretest:scripts` of `prettier --check "scripts/**/*.mjs"` (reachable via the pre-hook round 31 added) was enough: the probe-B rename to `*.spec.mjs` then passed while `node --test` silently ran 12 of 18 tests. Now scoped per command segment to the ones invoking `--test`, exactly as `typecheckProjects` gates on `tokens.some(isTsc)`. The JSDoc paragraph claiming a surplus token can't suppress a miss is corrected — it was false. 2. The gate-integrity block is extracted as `testScriptProblems(scripts, testFiles)`, pure and outside `main()`. The nit-4a branch added last round was the third consecutive commit whose newest branch sat outside the test seam and mutation-survived; extracting the block ends the pattern rather than pinning one more condition from the outside. Verified. The finding-1 probe (prettier pre-hook + `*.spec.mjs` rename) now exits 1 where it exited 0; the hook alone still exits 0. Mutation testing over the whole helper — empty-harvest branch to `if (false)`, segment gate removed, wiring axis removed, non-empty axis removed, segment split removed, `reachableScripts` to `Object.keys`, `matchesTestGlob` to equality — kills 7/7, including the branch that survived the last three rounds. `test:scripts` 21/21 · `verify:typecheck-coverage` OK 894 · `verify:format-coverage` OK 919 · `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-34 — harvest only positional args; normalize `./` Both findings are the axis round 33 fixed, one level in. 1. False pass. The segment gate stopped a neighbouring COMMAND's glob, but within a kept segment the filter was still "any non-flag token", so a glob-valued flag's VALUE was harvested as a positional arg. `--test-coverage-include "scripts/**/*.mjs"` is broader than the test glob and matches a renamed `*.spec.mjs`, so it vouched for the very file the runner skips — and it isn't hypothetical: `scripts/` sits outside the ≥90 coverage gate, so that flag is the obvious next thing added here. Tokens preceded by a value-taking `--test-*` flag are now dropped. 2. False failure. `./scripts/**/*.test.mjs` — which `node --test` accepts, and the common npm-script idiom — matched nothing, because `git ls-files` emits no `./`. Both files were then blamed for a rename that never happened, the unfollowable-remediation shape fixed for the bare-runner case last round. A leading `./` is normalized off, as `rootRunsClientValidate` already does. Nit 4: the gate-integrity footer's typecheck-wiring advice is now conditioned on at least one issue being about the typecheck wiring — a `test:scripts` failure carries its own per-line remediation, and appending `--noCheck`/`tsc -b` advice under a renamed-test-file message sends the reader after the wrong thing. Verified. The coverage-include probe with the rename now exits 1 where it exited 0, and exits 0 without the rename; the `./` probe exits 0 where it exited 1; a `test:scripts`-only failure no longer prints the typecheck footer. Mutation sweep 9/9 killed, including both new rules. `test:scripts` 22/22 · `verify:typecheck-coverage` OK 894 · `verify:format-coverage` OK 919 · `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-35 — fourth axis: flags that narrow the run 1. False pass on a new axis. The three axes ask whether the tests are run, whether there are any, and whether the runner is told about each — none asks what it then DOES with them. `--test-shard 1/2` keeps every glob intact and executes 6 of 22 tests, exiting 0, with the guard green; `--test-only` runs 2, as does a non-matching `--test-name-pattern`. This is `--noCheck` for the test runner, one domain over. Adds `NARROWING_TEST_FLAGS` and a fourth axis in `testScriptProblems`. Three of those flags were already in `VALUE_TAKING_TEST_FLAGS` — the guard knew them well enough to drop their values but not that they shrink the run. Both `--flag value` and `--flag=value` report as the bare flag name. 2. The footer conditioning added last round was itself inside `main()` — the pattern the same commit's comment documented, recurring in the commit that documented it. Extracted as `integrityAdvice(problems, nonTypecheck)`. Doing that fixes nit 3 in the same move: the old condition keyed off `testScriptIssues` specifically, so it covered one of three non-typecheck categories. A sibling-vouch failure ("the root validate no longer runs verify:format-coverage") and client-enrollment problems still got `--noCheck`/`tsc -b` advice about a typecheck pass they have nothing to do with. All three sets are now excluded. Verified. `--test-shard 1/2`, `--test-only` and `--test-name-pattern zzz` each now exit 1 naming the flag, while node runs 6/2/2 of 22. A sibling-vouch failure no longer prints the typecheck footer. Mutation sweep 12/12 killed, including all three new rules and the branch this commit replaces. `test:scripts` 24/24 · `verify:typecheck-coverage` OK 894 · `verify:format-coverage` OK 919 · `npm run ci` green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014vgJ6ZYj9VLhfSjgua48zw * chore(scripts): round-36 — discover test files by content, not name 1. False pass on the axis underneath the other four. The required test-file set was built with the same name pattern the `test:scripts` glob uses, so a rename escaping BOTH was invisible: the file left `testFiles` entirely, so nothing asked whether the runner was told about it, and the survivor satisfied the non-empty axis. A dot→hyphen slip (`npm-scripts.test.mjs` → `npm-scripts-test.mjs`) dropped 6 of 24 tests with every gate green — and the file that stops running is the one pinning the r16 prefix-sibling and r20 tail anchors, the series' two other false passes. Round 30 fixed "renamed to a form the glob misses" by broadening the name pattern; a fifth name pattern only moves the boundary again. `node --test` decides what a test is by whether it registers tests, so `isScriptsTestFile` reads that instead — the same measure-don't-model move as r25 and r32. It also covers what no name pattern can: a NEW test file added under a name the glob misses, never run and never noticed. Nit 2: `enrollmentProblems` no longer suppresses the footer. "declares no `typecheck` script …" IS about the typecheck pass and the footer's first clause is its canonical fix; excluding it lost the advice for the r15 rename scenario. The criterion is "is this about the typecheck pass at all", not "does it carry per-line advice" — several typecheck problems carry their own and still want the footer. JSDoc corrected accordingly. Nit 3: the complementary-shard boundary (`1/2` + `2/2` across two reachable scripts genuinely runs everything, and is flagged anyway) recorded on the helper, alongside the guard's other documented boundaries. Nit 4: the three `--test-coverage-{lines,branches,functions}` thresholds added to VALUE_TAKING_TEST_FLAGS. Their values are numeric and so inert rather than suppressing, but model completeness is cheaper than re-deriving that later. Verified. The hyphen rename now exits 1 naming the file; the `.spec.mjs` rename is still caught; an enrollment failure prints the footer again; the guard is unchanged at 894 files OK (exactly the 2 tracked test files reference `node:test`, none of the other 12 `scripts/` files do).

False failure. The predicate matched a bare `node:test` mention, so a shared helper importing the runner's `mock` API — registering no tests — was enrolled as a required test file and told to rename itself to `*.test.mjs`, which would only make node run an empty file. `scripts/lib/` is already the repo's shared-helper location, so this is the plausible next file there. Tightened to node's actual criterion: an import/require OF `node:test` AND a test registration. 2. Regression. `readFileSync` was passed as an argument, so it ran for every tracked `scripts/` file before the predicate's extension gate could reject it — a file in the index but not the worktree (`rm` without `git rm`) took the guard down with a raw ENOENT stack, aborting phase 1 before any real finding printed. Discovery did no reads at all before round 36. Extension is now gated first and the read wrapped: an unreadable tracked file warns and is skipped, the round-6 precedent where a failed `tsc` echoes its diagnostic instead of dying. Verified: the mock-helper probe exits 0; the tracked-but-deleted probe exits 0 with a one-line skip warning instead of a stack; the dot→hyphen rename is still caught.

fix(core): register peer-request handlers before connect (#1797) (#1798)
* fix(core): register peer-request handlers before connect (#1797) The roots/sampling/elicitation capabilities are advertised on the SDK `Client` at construction, so from the moment `connect()` sends `notifications/initialized` the server may issue any of those requests. The handlers, however, were registered after the handshake resolved and after `fetchServerInfo()` — leaving a window in which the SDK answered `-32601 Method not found`. `server-filesystem` asks for `roots/list` the instant it is initialized (that is how it learns its allowed directories) and lost the race, so it silently fell back to its CLI-argument directories instead of the roots configured in the Inspector. `server-everything` asks later and did not. Extract the four peer-request handler blocks into `registerPeerRequestHandlers()` and call it before `client.connect()`. None of them depend on server capabilities — only on constructor-set state. The notification handlers that do gate on `this.capabilities` stay in `connect()`, after `initialize`. Regression test drives the race deterministically with a fake transport that delivers `roots/list` synchronously from inside the `send()` of `notifications/initialized`; it fails on the pre-fix ordering. Closes #1797 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-1 fixes — pre-connect roots/list_changed, wider timing test (#1797) Finding 1: `notifications/roots/list_changed` was the one handler in the post-handshake block that gates on nothing but constructor state, so it sat in the same race — a server emitting it right after `initialized` had it silently dropped (no wire error; the symptom is a missed UI refresh). Moved to a new `registerPeerNotificationHandlers()` called next to `registerPeerRequestHandlers()` before `connect()`. Finding 2: the timing test asserted one of the four moved handler blocks. It now injects `tasks/list` and the `roots/list_changed` notification in the same burst as `roots/list`, so moving any of the block back after `connect()` fails the test. Sampling/elicitation stay out — they park a pending request awaiting user input and have no reply to assert on. Dropped the unused `sessionId`/`setProtocolVersion` transport fields. Verified the added assertions are load-bearing: the notification assertion fails against the previous commit, the `roots/list` one against `origin/v2/main`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-2 fixes — correct the roots/list_changed premise (#1797) The round-1 doc comment claimed a server may emit `notifications/roots/list_changed` at initialize. It can't, normally: `RootsListChangedNotificationSchema` is a member of `ClientNotificationSchema` and absent from `ServerNotificationSchema` — the client sends it (setRoots does, at :4251). The inbound handler is defensive coverage for a non-conformant server, and dispatches `rootsChange` with our own already-known roots. Reworded the method doc and the test's header so neither states the false premise; the move itself stands (it gates on no server capability, so it belongs with the request handlers). Also from review: - Dropped the vacuous `notificationRejected` flag and its inverted comment. The SDK does not throw for an unregistered notification, so the try/catch could never observe one — confirmed by bisect, where the pre-fix failure was always `rootsChanges`, never the flag. Removing the catch also stops it swallowing a genuine throw from the injected requests. - Narrowed `replies` to responses (`"result" in message || "error" in message`) so it can't also collect client-originated requests. - Annotated the unreachable `if (!this.client)` guard with a justified `v8 ignore` per the AGENTS.md dead-guard policy. Re-verified both regression directions: the `roots/list` assertion fails against `origin/v2/main`, the `rootsChange` one against `55e25b7c`.

The new timing test asserts exactly that non-empty dispatch. Replaced with one accurate line. Comment-only. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(cli): advertise roots so roots/set is actually serviceable (#1797) Round-4 review found the same -32601 symptom on a second path: the CLI constructed its InspectorClient with no `roots` option, so `capabilities.roots` was never advertised and no `roots/list` handler was registered — yet `--method roots/set` calls `setRoots()`, which announces `notifications/roots/list_changed` to the server. A server taking up that invitation got "Method not found", after the CLI reported success. The review's suggested fix — register `roots/list` unconditionally — is not implementable: the SDK asserts the client capability inside `setRequestHandler` ("Client does not support roots capability"), so it throws during connect for any client built without the option, and `registerCapabilities` refuses to run after connect. A client that omits `roots` therefore cannot legally serve `roots/list` at all. Fixed at the layer that can fix it: `cli.ts` seeds `roots: []`, matching web (`App.tsx` always passes it). The core registration stays gated on the constructor value, now with the SDK constraint documented so the next reader doesn't retry the unconditional version. `setRoots()`'s doc claimed it "will enable roots capability if it wasn't already enabled" — it cannot, for the reasons above. Corrected, and dropped the dead `if (this.roots === undefined) this.roots = []` the very next line overwrote. Tests: a CLI test drives `list_roots` over an HTTP test server (verified load-bearing — without the seed it fails on the -32601 error text), and the core timing test gains a case pinning that roots set after connect are served with the current values, not the constructor's. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(cli,tui): advertise the roots configured in mcp.json (#1797) Round-5 review: seeding `roots: []` fixed the -32601 but not the outcome. `server-filesystem` discards an empty roots answer (`validatedRootDirs .length > 0`) and keeps its CLI-argument directories — which is the symptom this PR set out to fix. The user's roots were already in hand two lines away, on `serverSettings.roots` (lifted from mcp.json by `mcpConfigToServerEntries`). Now passed through `cleanRoots`, the same shared helper web uses, so both clients answer `roots/list` byte-identically for the same config. This matters most on the CLI because it is one-shot: `--method roots/set` sets roots on a connection torn down a few statements later, so the config file is the only durable way to give a run its roots. Same gap in the TUI (`App.tsx` built its options with no `roots` key at all), fixed the same way. The review suggested a follow-up issue for it; folding it in here instead, since it is the identical line and splitting it would leave a known-wrong client in tree. Also from review: hoisted `waiters` up with the other fields, and `injectRequest` now rejects after 1s naming the method and id rather than hanging to the vitest timeout. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-6 fixes — document roots in the CLI README, harden cleanRoots (#1797) - clients/cli/README.md enumerated the settings lifted from a catalog/config file without roots. Roots are the least discoverable member of that list — there is no flag, and `--method roots/set` dies with the connection — so the file is the only durable way to supply them. Said so. - cleanRoots() trusted its input's shape. `Root[]` is a compile-time type over hand-editable mcp.json, and as of this PR all three clients feed it straight from disk, so `"roots": [{"name":"Work"}]` or `"roots": "file:///work"` threw at connect. Non-array bails to []; an entry without a string uri is dropped with a warning. Hardened in the one shared place rather than three call sites. Review suggested a follow-up issue; folded in for the same reason as the TUI fix last round. - Test comment said the CLI passes a `roots: []` seed — true one commit ago. - injectRequest clears its timeout on reply (an armed timer outliving a test is the #1760 teardown class), and setRoots' doc drops the "despite what this comment used to claim" archaeology.

Reproduced against the shipped function body before fixing. A bad `name` now costs the name, not the root (it is optional, and the uri is still usable), with a warning. The doc no longer overstates what is validated. Also from review: the CLI test comment said "`cli.ts` now seeds `roots: []`" — true only of that ad-hoc test's path; and the registration comment's `(:588)` line reference is now a durable name. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(core): normalize roots in setRoots() too (#1797) Round-8 review: this PR made cleanRoots the single normalizer for roots at connect and at save, but setRoots — the third way roots enter the client — did a bare `this.roots = [...roots]`. Web cleans at its call site; the CLI does not, so `--method roots/set --roots-json '[{"name":"Work"}]'` stored a root with no uri, advertised it in the roots/list reply, and echoed it back as success. cleanRoots is idempotent, so calling it inside setRoots covers the CLI without disturbing web's pre-clean, and all three entry points now agree. Review filed this as an optional follow-up; folding it in for the same reason as the TUI and cleanRoots items — it is smaller than the issue describing it. Test asserts the malformed entry is dropped and the valid one survives; verified load-bearing against the bare-spread version. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-9 fixes — normalize roots in the constructor too (#1797) The round-8 commit claimed "all three entry points now agree"; review pointed out the constructor is a fourth, and the only one still raw. All three clients clean at their call site, so nothing was broken — but the invariant was enforced by convention rather than by the class, at the very entry point this whole thread started from. `this.roots` now runs through cleanRoots, with a ternary so the `undefined`-vs-`[]` distinction that gates capabilities.roots survives. Also from review: - The CLI roots/set test provoked a cleanRoots warning without suppressing it (AGENTS.md). Suppressed, and the spy now asserts the drop was reported rather than silent. - `enables roots when previously undefined …` in coverage-backfill was named after behaviour round 5 established does not exist. Renamed, with a comment on what that client actually can and cannot do. - setRoots dispatches a copy to rootsChange, as getRoots() already did, so a listener can't push into the list we advertise. - run-method.test.ts's connectStdio now passes `roots: []` like cli.ts, so the helper matches the client shape production builds. Verified load-bearing: the constructor test fails against the raw assignment. validate / coverage / build-gate / smoke / storybook all green (run as separate stages — full `npm run ci` kept being killed mid-coverage by the environment). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-10 fixes — copy at both rootsChange dispatches (#1797) Round-9 claimed setRoots' copy closed the "a listener can't push into the list we advertise" hole. It closed one of two sites: my reply conflated the notification handler's *dispatch* with the roots/list *request* handler — the latter is serialized to the wire immediately and is fine, the former hands listeners the internal array. Both copy now. Also from review: dropped the `({}) as never` in the new constructor test for the real factory the sibling tests use (this test never connects, so it is never invoked), and the needless `async` on it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-11 doc fixes; merge v2/main (#1797) - cleanRoots' opening sentence still framed it as the settings-form normalizer, contradicting the paragraph below it that says every client feeds it from disk. It has four callers now; says so. - Marked the two runtime guards `Keep:` with the reason. The `Root[]` parameter narrows both to `never`, so "the compiler says this can't happen" is the argument someone will use to delete the checks rounds 6-7 installed. The reason now lives where the deletion would happen. - Noted the constructor-normalization case in the timing test's header, so it is discoverable from a file otherwise about the initialized race. Also merged origin/v2/main (#1796, loopback binding), which had advanced by one commit and touched the smoke scripts. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(core): clear queued peer requests when connect() fails (#1797) Round-12 review found a second-order consequence of the handler move. Before it, registration happened after every await in connect(), so the moment a peer request could be queued the connect could no longer fail — queue and failure path never overlapped. Registering before the handshake puts both the handshake and the post-connect `setLoggingLevel` inside that window. The catch sets status to error and drops the transport but never cleared pendingSamples/pendingElicitations; only disconnect() does, and connect() reaches it solely on the connect-timeout path (not the default). So a server that elicits at `initialized` and then fails the connect left a live pending-request modal on a dead connection — web derives it from the queue lengths with no status gate — and the elicitation's cancel() never fired, hanging any awaitUrlElicitation waiter. Extracted disconnect()'s clear-and-cancel into clearPendingPeerRequests() and called it from the catch, dispatching the change events so the UI drops the modal. CLI/TUI are unaffected either way (sample/elicit off). Test note: the first version of this test passed with and without the fix — its `requestedSchema` omitted `properties`, so the SDK rejected the inbound params and nothing was ever queued. Fixed the fixture; it now fails without the change with a queued ElicitationCreateMessage. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(core): clear the peer-request queue on a mid-session crash too (#1797) Round-13 review, two items. The test asserted only `getPendingElicitations()`/`getPendingSamples()`, which read the arrays directly — but the arrays are not what removes the modal. `usePendingClientRequests` tracks its own state off the pendingSamplesChange/pendingElicitationsChange events, so a regression that cleared without dispatching would strand a live modal on a dead connection and stay green. Both tests now assert the events fired with an empty payload; verified by deleting just the dispatches, which fails them. The connect-failure fix left the other way a connection ends uncovered: a mid-session crash goes through the transport's `onclose`, which sets status and fires `disconnect` but never touched the queues. Same two hazards, and arguably more reachable. `clearAndAnnouncePendingPeerRequests` wraps the clear plus its events, guarded on a non-empty queue so the paths that overlap (a connect failure whose dropCachedTransport also fires onclose) announce once; called from both. New test queues an elicitation, fires onclose, and asserts the queue and the event — fails without the change. Review flagged the crash path as a follow-up; folding it in, as with the earlier out-of-scope items — it is the same seam and three lines. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-14 fixes — make both teardown paths agree (#1797) - The crash path's comment claimed "cleared before the `disconnect` event so a consumer sees an empty queue" while disconnect() cleared *after* its own dispatch — an invariant stated as a property and held at one of two sites, the same shape as the round-10 finding. Moved disconnect()'s clear above its status/disconnect block so both paths agree; its change events stay batched with the other teardown dispatches. Full gate green, so nothing depended on the old ordering. - clearPendingPeerRequests' doc still named the `connect()` failure path as a caller; that path now goes through clearAndAnnouncePendingPeerRequests. Names the two real callers. - The mid-session test waited on `await Promise.resolve()` — the microtask-counting pattern this file replaced with injectRequest two rounds ago, working today only because the enqueue happens exactly one tick deep. Waits on the client's own `newPendingElicitation` instead. - The file header still called the constructor case "the last case"; it is third of five, and the two teardown cases went undescribed. Rewritten. - Restored the missing blank line between two tests, and noted why the sampling-event assertion holds for a queue that never held anything. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-15 fixes — scope the parity claim to the arrays (#1797) Round-14 made the two teardown paths agree on when the queue is cleared, and the comment then claimed parity flatly. It holds for the arrays but not the events: the crash path announces before `disconnect`, while disconnect() batches its change events with the rest of its teardown, so they land just after. Since the events are what drives the modal, the distinction matters to the next reader. Scoped the comment rather than un-batching — un-batching would trade a documented ordering for a real behaviour change with no gain. Same rule as round 14, one level down: check the other site, then check the other axis. Also gave the new `newPendingElicitation` wait the timeout that `injectRequest` documents, so a regression that stops the enqueue fails at the wait instead of hanging to the vitest timeout. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * test: pin disconnect()'s clear-before-announce ordering (#1797) Round-14 moved clearPendingPeerRequests() above disconnect()'s status block so a `disconnect` consumer sees an empty queue on both teardown paths, and round 15 documented it — but nothing enforced it. The existing `disconnect` listeners only count events, and the two teardown tests cover the crash and connect-failure paths, neither of which goes through disconnect(). So the one behavioural change in the stack was untested in both directions, and the tidy that undoes it (regrouping the clear with the batched change events) would have stayed green. Test records the queue length from inside a `disconnect` listener; the fixture's close() never fires onclose, so it exercises disconnect()'s own ordering rather than the crash path. Verified against the pre-round-14 position: `expected 1 to be +0`. Folded the newPendingElicitation wait into a shared helper now that two tests use it.

That is the path most likely to have a modal open when it runs. Asserted after the await rather than inside the disconnect listener, since disconnect() batches the events deliberately; verified by deleting the dispatches (`expected undefined to be +0`). Header rewritten by category rather than position: it has now gone stale twice in three rounds because it counted tests ("the last two") and enumerated paths that a new test falsified. It names the three teardown paths and what distinguishes them instead.

True only if "announcing" means the `disconnect` event: the connect-failure path emits none at all, and both it and the crash path clear after their `statusChange`. Scoped to what's true. Same shape as rounds 10/14/15 — a parity asserted in prose that holds on one of the axes it could mean — which is now the fourth time, in a sentence I wrote. ElicitationCreateMessage.cancel()'s doc still credited `disconnect()` teardown; this PR made clearPendingPeerRequests() its only caller, serving three paths. Re-attributed, and promoted the no-`onRemove` note to its own paragraph with the consequence spelled out — it quietly became a three-caller invariant during this PR, and "don't splice mid-iteration" reads like a style note until you know it would skip every other entry and leave those promises unsettled. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(core): gate roots/list on what was advertised, not on this.roots (#1797) Round-19 review found a latent wedge, reproduced before fixing: a client constructed without `roots` that later calls setRoots() has this.roots defined, so registerPeerRequestHandlers tried to register the handler on every subsequent connect() — and the SDK throws "Client does not support roots capability" from setRequestHandler when the capability was never advertised. That throw lands before the handshake, so the client can never reconnect. Worse than the -32601 this PR started from: the connection is gone rather than answering one method badly. Not a regression (the same gate lived after the handshake before) and unreachable from the three shipped clients, which all pass roots. But core/ is a library surface, and the failure is unrecoverable. Gate now reads a construction-time `rootsCapabilityAdvertised` — the thing the SDK actually asserts on — so this.roots stays free to change. setRoots' doc says what does happen on such a client: the roots are stored and readable, but no server can ask for them. Also scoped the header's claim that the connect-failure path emits no `disconnect`: true of connect()'s own catch, but on a real transport dropCachedTransport's close() fires onclose first, which does dispatch one — making the catch's own call the auth-recovery backstop.

Adding any term to the advertisement condition would leave the flag true with `capabilities.roots` absent — the same unrecoverable wedge, reintroduced silently and in the throwing direction. Now read off the built capability object after it is assembled, so divergence is structurally impossible rather than merely absent. Verified the reconnect test still fails against the old `this.roots` gate. Also: named the capability-lifetime category in the test header (the new test was none of the three it listed), moved that test below the teardown group so the group stays contiguous, and rewrapped the over-long comment line.

Reproduced before fixing: CONNECT ERROR: Client does not support elicitation capability (required for elicitation/create) Since #1797 moved registration before the handshake, that throw means the client cannot connect at all. Same wedge as the roots one, one capability over, and reachable through a documented option value rather than a future edit. Gated on a new elicitationCapabilityAdvertised, derived from the built capability object exactly as the roots flag now is. Test constructs with `{ form: false, url: false }` and asserts connect() resolves; verified load-bearing. Also made the four construction-time capability inputs (sample, elicit, receiverTasks, advertisedExtensions) `readonly`. The round-19 bug was a mutator making a construction-time fact stale, so a future setter for any of these should be a compile error rather than a review catch.

A server taking the invitation gets -32601: the advertise-then-refuse shape this PR opened with, and the last place it survived. Now built from capabilities.sampling / capabilities.elicitation, both decided just above, with the key omitted entirely if neither applies. Also made the remaining three registration gates read the built capability object like the two from the last two rounds — sampling, tasks/*, and the URL-elicitation completion handler. None could diverge today, but a mixed convention means the next reader has to re-derive which gates are safe, and adding one condition to an advertisement block is exactly how elicitation broke. Five gates, one rule now. Test asserts a receiverTasks+elicit:false client advertises tasks.requests with sampling and without elicitation; verified load-bearing.

Second client in the same test asserts `tasks` survives (list/cancel are still serviceable) while `requests` is absent rather than empty; verified against `requests: taskRequests`. The header regained a numeral four commits after round 17 rewrote it by category to stop exactly that, and it was already stale. Dropped, and named the third category — advertise-only-what-you-serve, which is about the capability object rather than a registration gate.

Round 13 recorded the samples-vs-elicitations asymmetry as deliberate on two grounds: nothing internal awaits a sample, and the transport is gone by then. The first still holds; the second is false on one path, and it is a path this PR created. `connect()`'s catch drops the transport only when `!transportHasAuthProvider`, so on the HTTP+OAuth path — web's ordinary authenticated case — it is retained and the caller reconnects over it. A sampling request queued during the handshake was then discarded with the connection still live: no response frame ever written, and the server waits forever for a reply to a request we accepted. Accept-then-silence, which is worse for the peer than the -32601 this PR opened with. SamplingCreateMessage.cancel() mirrors the elicitation one — settles (rejects, what the UI's decline path already sends and the SDK turns into an error response) without calling onRemove, since the caller iterates the queue and clears it. clearPendingPeerRequests loops it like the elicitations. Also corrected two comments that assumed the catch always tore the transport down, and noted that the retention is gated on transportHasAuthProvider alone — independently of isConnectAuthRecoveryError, which gates only the status hold. Test asserts settlement rather than a wire frame, since on the disconnect() path the transport is closed before the settle; a later respond() throwing "already resolved or rejected" is the proof. Verified load-bearing.

That promise only gets a consumer when the server polls tasks/result, so a task sitting in input_required has no handler attached — and the settle added last commit surfaced as an unhandled rejection. Not hypothetical: the repo already worked around it test-side, with a helper that reaches into private state to attach no-op catches, whose comment describes this exact race. Fixed at the source instead — one `void payloadPromise.catch(() => {})` at creation, which also covers the pre-existing cancelReceiverTask path. Removed the now-redundant helper and its two call sites. Verified: dropping the source line makes that suite report two unhandled rejections. Corrected SamplingCreateMessage.cancel()'s doc — its "no response frame is ever written" rationale is true of the plain shape only; a task-augmented sample already answered the wire with a CreateTaskResult, so settling it is about not leaving the task in input_required limbo. Nits: generalized the enqueue wait helper to both events so the sampling wait gets the timeout the elicitation one has; moved the sampling teardown test back into the contiguous teardown group; named the settle property in the header; fixed the fixture doc that still claimed to record replies.

Removed. Also reworded the surviving .catch() in inspectorClient.test.ts: it is still needed, but as a value capture for the assertion, not for unhandled-rejection suppression.

Probed it: the premise is wrong. The SDK asserts the notification capability too — `notification()` rejects with "Client does not support roots list changed notifications" and nothing reaches the wire. No spec violation and no invitation; what actually happened is that setRoots provoked that rejection and logged it as "Failed to send", implying a transient failure where the truth is structural. Kept the early return on that corrected basis: it stops us provoking a rejection we know will come, and warns accurately instead. Doc and comment say the SDK is the enforcer rather than claiming this guard is what keeps the wire clean. The test pins the end state (no invitation for roots we can't serve) and passes either way — recorded as such rather than presented as a regression guard, since it isn't one. Also moved the advertise-category test below the two gate cases, matching the order the header introduces them.

Identical today (roots are only ever advertised as `{ listChanged: true }`), but a conditional advertisement would un-gate it silently, which is the round-21 shape again. Split into rootsListChangedCapabilityAdvertised, mirroring urlElicitationCapabilityAdvertised, which already reads its assertion's sub-field; rootsCapabilityAdvertised keeps the roots/list registration, where presence is what setRequestHandler checks. Also moved the new test out of the gate pair it had split — it is a runtime-emission case, not a registration-gate one — and extended the header's converse-category paragraph to cover notifications, which indexes it without inventing a category. Reflowed the setRoots doc paragraph in one pass (111-char line from the last commit, plus a ragged orphan from an earlier edit).

That reword happened in core/, but the same premise had been written into the two comments justifying the CLI's roots seed, and they still asserted it. Both now state the real pre-fix failure: a server asking for roots on its own got -32601, and roots/set could not announce at all. Also fixed the warn message under the round-28 gate: it named the roots capability while the gate is on roots.listChanged — precisely the pair that split was made to distinguish, so a client advertising `{}` would have been told it advertised nothing.

That map holds the modern tasks/* frames the SDK's era gate refuses to route, so the SDK's chained _onclose doesn't know about them: a Tasks-tab poll in flight when the server died waited out its own 30s timeout and reported a timeout for what was a crash, on a connection that had already dispatched `disconnect`. Pre-existing — both the map and the crash path predate this PR. Fixing it here because the invariant it violates is one this PR wrote down: "every path that ends a connection has to clear that queue, announce it, and settle each entry", in clearAndAnnouncePendingPeerRequests' doc and the timing test's header. One channel was true of one path out of three. Test starts a raw-wire request and fires onclose; without the call it hangs to the vitest timeout, which is the symptom. Checked the two siblings and left both: taskInputAbortControllers is already unblocked via the elicitation cancel the crash path performs, and activeToolCallAbortController rides an ordinary client.request the SDK settles itself.

It is unavoidable — rawWireRequest is private and every public route is gated on isTasksExtensionNegotiated(), which needs a modern handshake the fixture doesn't perform — so that reasoning is now written down instead of left to be re-derived. - `await Promise.resolve()` was a no-op: rawWireRequest registers its entry in the promise executor, synchronously, before any suspension. Dropped, which also makes the test pin that ordering rather than paper over it — and stops the third recurrence of the microtask-counting pattern this file's own helper doc argues against. - Moved the test into the teardown group and extended the header's teardown paragraph to cover the outbound direction, which it framed entirely as inbound.

Round 31 established that scoping so the code wouldn't imply an impossible state; the prose then un-scoped it. Split into its own paragraph with its own scope clause, and reflowed both in one pass rather than nudging breaks.

Extracted `withTimeout`, used by the enqueue wait and the raw-wire assertion; injectRequest keeps its own since its timeout also deletes the waiter entry. On the failing path the raw-wire test left the production 30s timer armed, so a regressed run got the intended failure plus a stray unhandled rejection up to 30s later — the armed-timer class the file's own comment names, on the failure path. `settled` is marked handled before the race. Verified: with the fix removed the run fails with "raw-wire request not settled by teardown" and no unhandled rejection. Recorded why disconnect() drains the SDK's in-flight requests but rejects the raw-wire map outright: the user asked to disconnect, and a Tasks poll is not worth delaying that for.

Both were wrong: `Promise.race` attaches a rejection handler to every input, so `withTimeout(settled, …)` on the next line already marks it handled. Verified with a standalone script — no unhandledRejection fires, and the pre-fix version was equally safe. Removed the line and the comment. The comment mattered more than the line: it told the next reader that `Promise.race` does not mark its losers handled, which is false and would cost them elsewhere. Kept the true half by setting `timeout: 50` on that test's client, so a regression leaves no 30s timer armed and fails with `Raw request "tasks/get" timed out after 50 ms` — more self-describing than the raced generic message.

Verified it isn't one: `safeDisconnectTimeout` defaults to 0 and the only caller anywhere that passes a value is a single test, so nothing is drained in production; and the drain polls the SDK's `_responseHandlers`, which never holds raw-wire ids, so those were never eligible regardless. Reworded to what is true. The framing came from my own round-33 reply, which described the drain as running on every disconnect — a comment faithfully encoding a half-read mechanism, which is the same failure as the `Promise.race` one it followed.

Reworded: the short timeout is what fails fast and names itself, the race is the backstop for a promise that never settles at all. Race kept; it covers the case where the request's own timer is broken too. Third comment in three rounds encoding a mechanism the same commit changed.

Noted, so someone adding one later knows it would inherit a 50ms budget rather than reading the comment and looking elsewhere. The two installReceiverTaskResponseBypass guards read `this.receiverTasks` while the five gates around them read the advertisement. Installing the bypass mutates the Protocol's _requestHandlers map, so it is registration — same as the setRequestHandler it follows. Equivalent today; aligned so the convention is uniform rather than something the next reader has to re-derive per site. The genuinely-runtime `receiverTasks` reads are left.

The dead direction is the harmful one: if the tasks advertisement ever acquires a condition — the exact edit that produced the elicitation wedge — then advertised goes false while receiverTasks stays true, the bypass is not installed, and the handler still returns `{ task }` into the SDK's validating wrapper, which rejects it. That is the breakage the bypass exists to prevent, and before round 37 it could not happen because install and branch read the same field. All three now read tasksCapabilityAdvertised. `receiverTasks` is left where it belongs: assigned once, and driving the advertisement. Also noted that the wrapper's own check is redundant with its install guard and kept deliberately, since it must agree with the handler branch.

The crash path doesn't clear it, the connect() failure catch doesn't, and connect() never reset it — so a record created in one session survived into the next connect() on the same instance, and `tasks/list` is answered from that map. A new server would be told about a task it never created. Reachable in web (the only client with receiverTasks): a task-augmented sampling/createMessage arriving in the handshake window creates a record; if that connect then fails with a 401, App.tsx retries connect() on the same instance. Cleared at the top of connect() rather than only on the crash path — the auth-recovery retry means ending a session isn't the only way a new one begins, and starting clean covers every route in. disconnect() keeps its clear via the same extracted helper. Pre-existing — the crash path never cleared these — but the handshake window this PR opened is what lets a receiver task exist before connect resolves, and this was the one member left outside the invariant the PR documented.

Two of the other four have real symptoms on the same crash-then-reconnect path: - subscribedResources — the modern subscribeToResource early-returns on a uri already in the set, so after a reconnect the user's Subscribe click silently sends nothing to the new server while the UI keeps listing it. - cancelledTaskIds — a leftover id mislabels a *new* task sharing it as cancelled rather than failed, and server task ids are often short. taskInputAbortControllers leaked un-aborted controllers. modernLogLevel had the opposite asymmetry: disconnect() cleared it so it couldn't leak (#1629), but nothing restored it, so a reconnect after an explicit disconnect silently lost the user's configured level while a reconnect after a crash kept a mid-session override. It is now recomputed from serverSettings the way the constructor does, so both routes agree. clearReceiverTasks became resetSessionState, called from the same place. Tests cover the two symptomatic siblings and now assert receiver tasks through the `tasks/list` handler — what a server actually sees, and the symptom itself — which also removed the unjustified `as unknown as` the previous commit added. The remaining cast is justified in place, since cancelledTaskIds has no public reader.

On the one path that reconnects the *same* instance — auth recovery — the control then read Off while every modern request carried `_meta` logLevel "debug", the default. A tool whose job is showing what you send should not disagree with itself about what it sent. The control now re-seeds from the active server's settings exactly as setupClientForServer does, instead of blanking. Also from review: - Added the tests the restore never had, covering both halves: a mid-session override does not survive a reconnect, and a disconnect no longer drops the configured level (the #1629 half, and the actual behaviour change). - resetSessionState's doc claimed "every piece of state scoped to one connection", which invites assuming membership rather than checking it. Now states the rule: state a new session would misread; what only needs settling on the way out stays with the teardown paths. - Header: session-scoping paragraph moved below the outbound one to match test order, and it now names all five members rather than three.

The client and the Logs control agreed only because four sites happened to compute the same expression, and any drift reproduces exactly the symptom the previous commit fixed: the control reading one level while every modern request stamps another. Extracted resolveModernLogLevel into core/mcp/types.ts beside DEFAULT_MODERN_LOG_LEVEL; all four call sites use it, with the web mapping undefined→null at its own boundary (display, not a second derivation). Also from review: - disconnect()'s comment still credited itself with preventing the #1629 leak, which resetSessionState now prevents. It says what the line does now — read "not opted in" while disconnected — and notes the web control deliberately shows the configured level in that window. - resetSessionState's doc claimed an un-aborted taskInputAbortControllers entry "leaks a paused poll loop". Both registration sites release in a finally, so nothing leaks permanently; the abort closes the window between a crash and the unwind. Softened, and it now has the test it lacked — the only member of the five without one. - Noted in App.tsx that the re-seed depends on activeServerIdRef still holding the outgoing id (it syncs in a passive effect), so an eager clear would silently drop it to the default.

No symptom today only because the UI mirror resets itself independently, in another file — which is the arrangement this PR has spent its rounds removing. Clearing it here also announces the reset; that set's every other mutation dispatches. Also from review: - The web re-seed treated "no server found" as the default level rather than Off, because resolveModernLogLevel returns the default for absent *settings*. Reachable via a second disconnect after a crash, and via removing the active server. Now distinguishes the two. - Converged the two injectRequest copies: withTimeout takes an optional onTimeout, so both drop their waiter on the timeout path. The newer copy had lost exactly the cleanup that was round 33's reason for leaving the original alone.

My round-43 fix traded one wrong branch for another: it read `?.settings`, which is undefined both when no server matched *and* when the server has no settings node — and the second is the common case (a hand-written mcp.json entry never opened in Server Settings). Those servers showed Debug while connected and Off after disconnect, which is exactly the client/UI disagreement rounds 41-42 removed, with no modernLogLevelChange event to reconcile it. Now branches on the server. Worth noting no test would have caught it: App.tsx is a documented exclusion from the coverage gate. Also from review: - resetSessionState cleared subscribedResources without announcing it, two lines below a comment arguing that every other mutation of that set dispatches. And it took two statements of a six-statement cluster disconnect() clears together — leaving modernReconnectAttempts (a new session's first drop would back off as if it were the old one's nth), modernListenGeneration (the bump that makes an in-flight re-listen bail), and a stale modernSubscription. One resetSubscriptionStream helper now serves both, announcing both axes; disconnect() keeps only the live stream's best-effort close. That also removed the file's one assignment to modernStreamState that bypassed its setter. - The stream-state test pinned the value, not the dispatch — the half the UI actually tracks. Now asserts both; verified against a bare field assignment. - onModernSubscriptionClosed's comment claimed the disconnect reset always clears the set; on a crash it doesn't until the next connect. Says so.

Dead text where it sat, and the most load-bearing comment in the batch. Moved, not reworded. That is round 32's finding in production code, from the same cause: inserting anything between a doc block and its method is a move that needs checking, prose or code. Also from review: - resetSubscriptionStream announced the cleared set before updating the stream state derived from it, so a listener in between saw an empty set with an `active` stream — the combination the helper exists to prevent, exposed by its own dispatches. Both fields move first, then both are announced. The onModernSubscriptionClosed comment now says that window is never observable, which is newly true. - The test header called the log level "cleared"; it is re-seeded, which is the #1629 half of the test twenty lines below.

Not guaranteed on the connect path — an `onerror` without an `onclose` leaves the transport up, connect() reuses it, and the reset then drops the last reference to a stream still open on the server. Nothing can close it afterwards: the `closed` handler bails on the bumped generation, and `closed` never resolves for a live stream. Before the extraction the surviving reference was eventually closed by refreshModernSubscription as `previous`, so this was newly unclosable. The helper now closes it itself, best-effort, after the dispatches so the round-45 ordering is unaffected; disconnect() drops its two hand-rolled lines. Also from review: - The session test pinned the subscription set's value but not its dispatch — the half the UI tracks, and the gap round 43 closed for the stream axis one line away. Both now asserted; verified load-bearing. - resetSessionState's doc said disconnect() "clears all of this", which is true by duplication for two of the five members; it now says a sixth has to be added in both places. And "the teardown paths" handle the in-flight tool call only on the disconnect route — on a crash it is callTool's own finally. Named.

It is two and three — and the member the enumeration dropped is the one that is *paired* rather than duplicated: modernLogLevel is re-derived here and blanked in disconnect(), deliberately. Both corrected. - `subscription.closed.then(...)` had no rejection handler, unlike every other promise around that stream. Newly reachable: before the last commit a connect-path reset dropped the reference with `closed` permanently pending, so the chain never settled at all; closing the stream is what makes it settle. Added, with the Node-terminates reasoning the file already applies to payloadPromise. - The listen-stream test exercised transport reuse without asserting it — the half that makes "still open on the server" true. Counts factory calls now, so the premise fails loudly if a future change recreates the transport rather than silently ceasing to apply. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-48 — scope the catch, guard the close, index the test (#1797) - The .catch comment claimed the connect-path close made a *rejecting* `closed` reachable. It doesn't: closing resolves it. What that close newly reaches is the handler running at all, where the reference used to be dropped with `closed` pending forever. And chaining after `.then` also swallowed handler throws — silently abandoning a re-listen on the path whose job is recovering a dropped stream. Now the second argument to `.then`, scoped to the rejection, with the comment saying which half is which. - `closing?.close()` reaches into third-party code from `disconnect()`'s straight-line teardown, none of which is inside a `try` — a synchronous throw would skip the raw-wire rejects, the task aborts, the receiver-task clear and nine dispatches, silently, since most callers catch a disconnect(). Best-effort now against both failure modes. - Header indexes the listen-stream test: same category, but a release obligation rather than a misread one. - Its comment described the generation guard, which the stub can't exercise; marked as production behaviour. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-49 — pin the best-effort close, unorphan the doc (#1797) Round 48 made `resetSubscriptionStream`'s close best-effort against both a rejected promise and a synchronous throw, but nothing exercised either arm: both `modernSubscription` stubs in the tree resolve. On the `disconnect()` path an escaping failure would silently skip the raw-wire rejects, the paused task-input aborts, the tool-call abort and `clearReceiverTasks()` — the findings rounds 13 and 30 closed, re-opened at once with a green suite. Two table-driven cases now seed a `close()` that throws and one that rejects, and assert teardown continued past it. Also: the `.then` comment gave opposite verdicts on one mechanism (an unhandled rejection is named unacceptable, then chosen for a handler throw) — reworded to say the handler cannot throw today and why the shape is defensive; and `refreshModernSubscription`'s doc block, orphaned two methods up since before this branch, moved onto the method it describes. Closes #1797 * review: round-50 — sweep the queues start-clean, unify the close (#1797) `resetSessionState`'s doc excluded the peer-request queues and the raw-wire map because "the teardown paths handle them" — true of the paths that run. An `onerror` without an `onclose` runs none of them: it flips status to "error" and leaves `baseTransport` cached, so a `connect()` on the same instance reuses a live transport. That is the route the round-46 stream close was built on, and it strands these two the same way — the web pending-request modal is derived from the queue length with no status gate, so it outlives the session, and answering it writes a response for the old request id onto the new connection. Both are now swept start-clean beside the reset (both helpers are idempotent, so the routes that already ran them are unaffected), the end-clean clears stay put for the `disconnect`-event consumer, and both docs say which is which. Also folds the three subscription `close()` sites onto one `closeSubscriptionBestEffort` helper, so all three absorb a synchronous throw as well as a rejection — at `refreshModernSubscription`'s first site the reference is already dropped, so a throw there both leaks a live stream and aborts the refresh before its replacement is opened. Closes #1797 * review: round-51 — pin the sweep's ordering, name the category (#1797) The connect-start sweep must sit after `resetSessionState()`, and the two calls read as independent. Cancelling a task-augmented peer request settles it synchronously into the record callback, which ends in `upsertReceiverTask` — a no-op only because `clearReceiverTasks()` just emptied the map. Hoisted, it would emit a `notifications/tasks/status` for the outgoing session's task onto the transport the connect is about to reuse. Stated at the call and pinned by a test (which fails on the hoist). Adding that third caller also made five docs stale, all describing the old set by count or as "teardown" — the class round 23 diagnosed. All five now name the category: every route out, plus the top of `connect()` as a backstop for the one route in that settles nothing. And the site where round 50's fold actually changed behaviour — `refreshModernSubscription`'s first close, where the reference is already dropped and a `.catch()` never caught a synchronous throw — is now tested from the public surface (a re-list over a poisoned stream), table-driven over both arms. Verified to fail on the pre-fold form. Closes #1797 * review: round-52 — say what the sweep prevents, scope the close doc (#1797) The sweep's comment named as its harm the exact write the sweep performs: on this route the SDK's transport is still live, so cancelling a queued peer request emits a response for the old id immediately — which is right, and is the settle-don't-discard rule, at the best available moment. As written it read as an argument against emitting the frame, inviting the clear-without- settling regression rounds 24–25 removed. It now names the real hazard: a *user*-authored answer landing arbitrarily later, past the re-handshake. `closeSubscriptionBestEffort`'s "at each site" held at two of three — the superseded-generation discard stored nothing and has nothing following it, so its escaping failure would only reject an already-superseded `subscribeToResource`. Scoped, still wrapped. Also moves the `disconnect()`-side close pair next to its `connect()`-side twin, and states which axis the file's ordering follows, since route and category both describe it and cut differently. Closes #1797 * review: round-53 — give each close site its real harm, pin it (#1797) The doc grouped `resetSubscriptionStream`'s close with the "takes the caller's remaining work with it" sites. It can't: the call is `void`-ed onto an `async` helper, so even a synchronous `close()` throw becomes a dropped rejection — `disconnect()`'s teardown runs regardless. The harm there is an *unhandled* rejection, which this PR already established (the payloadPromise fix) is the process-fatal class in Node — so the one site with the severe failure mode was documented as having the mild one. Each site now carries its own consequence, and the local comment no longer gives two reasons that cancel each other. The test had the same gap: both its assertions hold with the helper's try/catch deleted. It now also asserts no unhandled rejection fired, which does fail without the guard (verified on both arms); the teardown assertions stay, since they still catch unwrapping the call to a bare `close()`. Also names the two back-references the round-52 move left positional, and softens the "on the wire until dropCachedTransport()" claim — that drop is conditional and never runs on stdio. Closes #1797 * review: round-54 — the mildest site isn't mild from every caller (#1797) `refreshModernSubscription` has three callers, and the superseded-generation discard's failure reaches all of them. From `unsubscribeFromResource` — which deliberately keeps the removal when a re-listen fails — it surfaces "Failed to unsubscribe" for an unsubscribe that actually stuck, which is worse than the consequence the doc assigned to the site it called mildest. The re-listen bullet had the mirror gap: on the reconnect caller the escape is absorbed into the backoff run, not a set left with no stream. Both now name their callers, and the generation-bump claim is softened to what it proves (a newer refresh *started*). Test: the `unhandledRejection` listener is process-wide, so the assertion now filters to this fixture's own reason rather than failing on a rejection some other test left pending; and it is registered inside the `try` whose `finally` removes it, so a throw in the setup can't leak it into the rest of the file. Re-verified the filtered form still fails on both arms with the helper's try/catch removed. Closes #1797 * fix(core): don't roll back a subscribe a newer refresh superseded (#1797) `subscribeToResource`'s rollback assumes what its comment says — that the server filter is unchanged — which is exactly what supersession falsifies. The newer refresh built its filter from the set *including* this URI, so on success the server honors it; rolling back leaves the set missing a URI the live stream carries (the UI showing it unsubscribed while its resources/updated keep arriving) and, if it was the only one, an empty set with an active stream — the combination `resetSubscriptionStream` exists to prevent, reached from the other end. Reachable without any close() failure: a rejecting `listen()` propagates the same way, which a user subscribing while the reconnect timer re-lists — i.e. exactly when the server is flaky — can produce. The rollback is now gated on the generation not having advanced past this call's own bump; the error still reaches the caller either way. Test drives two overlapping subscribes with the first `listen()` rejecting, and fails without the gate. The doc bullet that called this the mild site is corrected with it: both user-initiated callers report a failure that did not happen, in mirrored ways. Also gives the two close-failure arms distinct reasons so the unhandled-rejection filter can exclude the sibling arm as well as a foreign rejection. Closes #1797 * fix(core): reconcile the stream badge when a re-listen this call owned fails The supersession gate left the both-fail case stuck: two overlapping subscribes whose listens both reject leave the superseded URI in the set (its rollback correctly skipped) while the state keeps the optimistic "connecting" — no stream, no reconnect armed (neither onModernSubscriptionClosed nor onModernReconnectFailed ran), so the badge never changes and no resources/updated ever arrive. That is the caveat this file already wrote down for the neighbouring case — the bump proves a newer refresh *started* — applied to the gate itself. Fixed in the branch that knows the answer: the call that still owns the re-listen reconciles the state instead of only handling an emptied set, reusing the "ended" badge onModernSubscriptionClosed already reports for "stream gone, URIs still subscribed". unsubscribeFromResource gets the same treatment — it rolls nothing back by design, but its failed re-listen left the badge reading Listening over no stream. Also: the gate's comment named one of the two things that bump the generation (resetSubscriptionStream also does, from disconnect and the start-clean reset) and cross-referenced the wrong invariant; both corrected, and `<=` tightened to `===`, which is what the monotonic synchronous bump actually guarantees. Closes #1797 * fix(core): order the subscription writes, retry instead of stranding Two sites emptied the subscription set and announced it before the stream state caught up — the last-URI rollback in subscribeToResource's catch, and (pre-existing) the ordinary last-URI unsubscribe, which dispatches a round-trip before the re-listen sets INACTIVE. Both exposed an empty set with an active stream: the pair resetSubscriptionStream orders its own writes to prevent, and which three comments in this branch now cite. State before the announce at both, asserted from the consumer's side. And the reconcile added last round settled for an honest but dead badge: it was the only route to "stream gone, URIs live" that had made no attempt at all, over subscriptions the server may never have honored, recoverable only by an Unsubscribe/Subscribe toggle (a fresh Subscribe early-returns). It now hands them to the reconnect machinery, which already fits — base delay after a user-initiated refresh, bails on a terminal status or an emptied set, and lands on the same "ended" badge past the cap. That also removes the provably-dead null check the reconcile carried. Closes #1797 --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

SDK v2 migration (behavior-neutral, versionNegotiation: 'legacy') (#1624)
Migrate all three clients + core + test-servers from
@modelcontextprotocol/sdk@1.29 to SDK v2 (2.0.0-beta.4), keeping behavior
identical against legacy (2025-11-25) servers. Foundation for the SDK V2 +
New Spec stack.
Packages
- Split @modelcontextprotocol/sdk -> @modelcontextprotocol/client (Client,
transports, OAuth, error taxonomy, protocol types) + core (Zod schemas);
stdio -> client/stdio, Ajv -> client/validators/ajv. Test-servers ->
@modelcontextprotocol/server (+ server-legacy/sse). Deterministic import
rewrite (schemas -> core, everything else -> client); the codemod misroutes
client code to /server so it was not used for path routing.
- new Client(..., { versionNegotiation: { mode: 'legacy' } }) — nothing
2026-era goes on the wire.
Runtime (core/mcp/inspectorClient.ts)
- Error taxonomy: McpError -> ProtocolError, ErrorCode -> ProtocolErrorCode;
RequestTimeout -> SdkError/SdkErrorCode.
- Handlers take method strings; task methods (tasks/*, notifications/tasks/*)
use the 3-arg custom form (excluded from v2's spec-method set).
- Legacy tasks kept working (per project requirement): requestor tasks re-
implemented over raw client.request + explicit deprecated schemas;
experimental.tasks.callToolStream replaced by a local pollTaskToolCall
async generator (with _progressHandlers revival so task-execution progress
still reaches the caller). Receiver (server-initiated) tasks: the v2 Client
validates a sampling/elicit handler result and rejects the legacy { task }
response with -32602 — installReceiverTaskResponseBypass swaps the wrapped
entry in the private _requestHandlers map for the task-augmented branch so
{ task } reaches the wire (fixes server-initiated sampling-via-task).
- Pagination: list verbs use raw client.request({method}, List*ResultSchema)
for single-page behavior (v2's client.listX() auto-aggregate all pages).
Web / auth / apps
- Rename local JsonSchemaType -> InspectorFormSchema + add toFormSchema()
structural narrowing at the SDK-schema -> form boundary.
- ext-apps still peers on SDK v1: one compat boundary with documented casts
(remove when ext-apps#702 lands a v2 peer).
- OAuth provider saveClientInformation reconciled with v2's
OAuthClientInformationContext; InvalidClientMetadataError re-homed as a
local class (server-legacy/auth is not browser-safe).
- vitest.shared.mts dedupes @modelcontextprotocol/client+core to one copy so
vi.mock intercepts the SUT's import.
Accepted v2 behavior changes (per #1624 / spec §9.2): unknown-tool call
rejects with -32602; cancellation is stream-abort (no guaranteed
notifications/cancelled frame); output-schema strictness restored via the
Inspector's own Ajv check on the default path.
npm run ci green: validate (web 3087 / cli 212 / tui 274 / launcher 5),
coverage (>=90 per-file, all clients), smoke (launcher/cli/web), storybook
(410).
Closes #1624

cli: address #1673 review — refresh fallback, 0600 write, distinct code
- Refresh failure now falls back to injecting a still-present stored access token instead of hard-exiting 3, so a transient auth-server hiccup doesn't regress a previously-working invocation (review #1). Only a failure with no access token to fall back on surfaces as exit 3. - Persist rotated tokens via the shared writeStoreFile (0o600 + mkdir -p) instead of a raw writeFile, so the secrets file keeps owner-only perms identical to the web backend (review #2). - Missing clientInformation now throws the distinct no_client_information envelope code rather than reusing no_stored_token (review #5a). - Docs: --wait-for-auth no longer claims parity with --use-stored-auth (it injects the freshly-landed token without refreshing); noted the always-refresh rotation/concurrency caveat (review #3, #4). - Tests: discovery-returns-undefined metadata path, no_client_information code, and an e2e refresh-failure → access-token fallback.

cli: stored-auth injection honors refresh_token, not just access_token (#1665)
Closes #1665 `--use-stored-auth` previously injected the stored access token blindly, so an expired token failed even with a valid refresh_token on disk. Now, when a `refresh_token` is stored, the CLI runs the OAuth refresh grant and injects the fresh access token, persisting the rotation. - New exported `refreshStoredAuthToken(serverUrl, statePath, deps?)`: reuses the SDK's `refreshAuthorization` (not a hand-rolled token request) with the stored `clientInformation` + `serverMetadata` (discovered via core `getAuthorizationServerUrl` + SDK `discoverAuthorizationServerMetadata` when the metadata wasn't persisted). Rotated tokens are written back through `serializeOAuthPersistBlob` under the same `{servers,idpSessions}` key, so web and CLI stay consistent. Missing refresh_token/clientInformation or a failed grant throw `CliExitCodeError(AUTH_REQUIRED)` with a clear message + envelope code (`no_stored_token` / `refresh_failed`). - `--use-stored-auth` prefers refresh when a refresh_token is present (covers both absent and expired access tokens — the stored blob has no expiry, so the refresh token is the durable credential); falls back to injecting the stored access token otherwise (unchanged). - `deps` are injectable so the refresh/discovery are unit-tested without a live token endpoint; an e2e test drives the real SDK path against a mock token endpoint and asserts the refreshed token is injected + the rotation persisted. - CLI README updated (removed the "blind injection" caveat). CLI coverage gate green (cli.ts 100/92/100/100). Part of the #1579 decomposition (Wave 4, CLI lane).
