Summary

  • ocx restart no longer refuses with restart_version_skew when the invoking CLI is newer than the running proxy. Instead it performs a stop/start from the current installation and verifies the replacement reports the CLI version, so updating the checkout and restarting actually updates the serving proxy.
  • Other skew directions (proxy-newer, incomparable) still refuse as before; the request layer now distinguishes them with a dedicated restart_version_skew_cli_newer code.
  • No server-side changes; the no-stop fallback invariant inside runProxyRestart is untouched.

Verification

  • bun run typecheck: clean.
  • bun test system-restart-client, package-tree, cli-version-skew: 49 pass, 0 fail.
  • Live-verified on a fork checkout: CLI vs older running proxy restarted via stop/start with version check (2.72.0 and 2.77.0 cases).
  • No GUI changes, no screenshot.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed (no user-facing config change).
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

  • Bug Fixes
    • Proxy restarts now handle cases where the installed command-line tool is newer than the proxy. The restart proceeds only after confirming the target proxy is unchanged and stopped.
    • A restart is successful only when the replacement responds on the expected port and reports the current command-line tool version. Stop, start, and verification failures are reported distinctly.
    • Version mismatch diagnostics distinguish a newer command-line tool from other mismatches.

Autopilot verification (head f9e916d, 2026-10-04 13:15:14): typecheck + bun test tests/cli/system-restart-client.test.ts tests/cli/restart-update-coordinator.test.ts green; change scope 9 file(s); full suite not run locally, remaining coverage left to CI.

📝 Walkthrough

Walkthrough

The restart client now distinguishes CLI-newer version skew from other version mismatches. For CLI-newer skew, the CLI checks the attested proxy identity, stops the proxy under guarded approval, starts the current installation, and verifies the replacement’s runtime identity, port, and version.

Changes

CLI proxy restart

Layer / File(s) Summary
Classify version skew
src/cli/system-restart-client.ts, tests/cli/system-restart-client.test.ts
The restart client returns restart_version_skew_cli_newer when the CLI is newer than the proxy. Tests assert the expected error for each version pair.
Coordinate guarded stop and replacement
src/cli/restart-update-coordinator.ts, tests/cli/restart-update-coordinator.test.ts
The coordinator checks that the resolved runtime matches the attested PID and port. It requests a guarded stop and waits for the target to stop responding before starting the replacement. It accepts the replacement only when its runtime identity, port, and CLI version are verified. Tests cover success and refusal paths.
Wire and document the update restart
src/cli/index.ts, docs-site/src/content/docs/reference/cli/lifecycle.md, structure/runtime.md, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
The CLI routes CLI-newer skew through the coordinator and reports success or distinct refusal reasons. The documentation describes the update path, and the test-layout mappings include the coordinator tests.

Merge Risk: ⚪ Minimal · up to a903f

The updated restart path appears ready to merge after normal checks. No actionable issue is established by the supplied evidence.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to a903f

The replacement path preserves strong identity and ownership checks. However, when saved configuration names a different port from the running proxy, restart can stop the working proxy, launch a replacement elsewhere, and leave it running after reporting failure. This creates a bounded but material lifecycle and recovery risk.

Retained concerns

  • Medium · reliability · inferred: When saved configuration and the live runtime use different ports, the CLI-newer path can stop the approved proxy, start a detached replacement on the configured port, and then reject it because verification requires the original target port. The replacement remains running, and startup can update client integrations before verification fails. This newly reachable failure state breaks endpoint-preserving replacement and leaves recovery outside the transaction; the previous skew refusal left the original proxy running.
Security review details

Security Blast Radius

  • inferred — The inspected authority path concerns the approved local proxy, its managing service, and local shared client-routing state. The new behavior exercises local stop/start authority rather than only requesting an in-place restart of the existing installation.

Trust Boundaries and Controls

  • observed — Before selecting the new path, the request client requires a runtime-sourced target, matching runtime PID and port, a valid fresh challenge proof, matching health PID, and supported restart capability.
  • observed — Guarded stop independently checks the resolved identity, configuration home, CLI version, ownership, compatibility fingerprint, tracked runtime, and manager binding under the ownership mutation lease. Changed or unverifiable approval is refused before the stop callback.

Resilience and Maintainability Implications

  • observed — The guarded manager step stops a bound manager before separately signaling its approved child when required. Successful settlement requires process exit, port availability, a definitively dead endpoint, and an inactive manager, with a final manager-state check before returning success.

Hardening Proposals

  • proposed — Carry the approved endpoint into replacement startup, or reject incompatible startup configuration before stopping. Define an ownership-bound terminal policy for a replacement that starts but fails verification, without stopping unrelated concurrent processes.
  • proposed — Consider binding lifecycle-decision fields, including reported version, into authenticated health evidence. This strengthens the existing identity proof; it is not a verified response-interception finding.

Add focused coverage for the CLI update-restart path.

tests/cli/system-restart-client.test.ts:150-178 checks the skew error code and that the client sends one request. It does not exercise the CLI fallback in src/cli/index.ts:923-981 or verify the stop/start and post-start checks. Add cases for stop failure, a non-started outcome, no live proxy, a version mismatch, and success.

Scoped correctness review at fe3cf0aa823afd4144ab240191939ec6145b1c45.

P2 — Preserve the observed restart target through the update fallback (src/cli/index.ts:920, src/cli/system-restart-client.ts:153).

The new CLI-newer refusal is returned before requestBoundSystemRestart performs its final sameRestartTarget recheck. runProxyRestart then returns only an error, and the outer handleProxyRestart calls restartViaStopStartForUpdate without the originally observed PID/port. That helper invokes handleStop() without a StopApproval; handleStop explicitly enters its unguarded current-owner stop path when approval is absent.

A concrete interleaving is: attest older process A, receive the CLI-newer result, let a supervisor replace A with process B in the same home, then enter this fallback. The stop now selects B rather than refusing the changed target. This discards the exact-process restart contract; leaving the no-stop fallback inside runProxyRestart textually unchanged does not preserve the contract when its caller performs the stop anyway. The existing new assertions only distinguish the error string and never execute the added stop/start helper.

Please carry the observed restart identity into an explicit coordinator, revalidate it under the ownership lease through the existing guarded-stop mechanism, and refuse a changed/unknown owner. Start only after the intended target and its supervisor are confirmed stopped, with bounded observation of the expected replacement. Add injected regressions for A-to-B replacement, uncertain/failed stop, start failure, and replacement identity/version checks; do not exercise a real service to test these cases. Update the owning restart/lifecycle documentation in the same patch, since this intentionally changes refusal into a stop/start transaction.

This is a decisive static control-flow/interleaving finding, not a claimed live restart reproduction, security scan, or full PR approval. No running proxy, service or client configuration was touched.

Thank you, the interleaving point is taken — the fallback indeed stopped whoever was live instead of the attested target.

Reworked in 2d1a1ac: the attested PID/port now travels into an explicit coordinator (src/cli/restart-update-coordinator.ts) that revalidates it under the ownership lease through runApprovedStop (changed/unknown/non-runtime owner refuses before any stop), starts only after the target shows stopped on a bounded wait, and accepts the replacement only when it serves this exact CLI version on the expected port.

Injected regressions cover A-to-B replacement, uncertain/failed stop, start failure, and replacement identity/version checks with no real service; structure/runtime.md and the CLI lifecycle docs updated in the same patch. No in-place path changed.

The scoped original PID-loss finding is resolved at 1ab7f56: attested PID/port carried to coordinator, guarded stop under ownership lease; 23 focused injected tests independently pass. This withdrawal is not final PR/CI or boundary approval.

Latest sync checkpoint: 8b3b8dd now includes dev3953f11f; GitHub reports mergeable, so the prior conflict hold below is historical. The new merge incorporates #6586/#6564/#6493. Restart runtime source is unchanged from f47cb93; the status readiness fixture's offline fetch assertion arrived through dev, not a new coordinator implementation. No repeat of unchanged restart tests or actual proxy restart was performed.

Current-head Cross-platform CI37218341807, Service lifecycle37218341869 and React Doctor37218341846 are action_required. These are not successes; the cleared conflict does not grant CI authorization, sponsorship or technical approval. Earlier scoped correction/dismissal evidence remains historical and the outstanding review/CI duties remain separate.


Previous checkpoint (historical):

Latest-head hold at 6df30d4, base815b1f609: the PR-specific restart coordinator/client/index and focused-test bytes are unchanged from4186bb789 in direct comparison; no old test count is relabelled as fresh. GitHub still reports mergeable:false. Current Cross-platform CI37214692951 is action_required, not passing; it replaces the older pending run in the checkpoint below.

Please reconcile your own branch with current dev, then revalidate/re-attest the resulting head and respond to the stale coverage advisory against the existing coordinator tests. No fork-workflow authorization, test rerun, live restart, branch edit or approval was performed by me.


Historical checkpoint:
Current integration hold at 4186bb7: GitHub now reports mergeable:false; required Cross-platform CI 37209856648 remains action_required, not passing. The contributor has re-attested readiness, but that does not resolve the conflict or authorize workflow execution. Please reconcile your own branch with current dev and provide exact-head validation/CI. The existing advisory thread asking for CLI update-restart coverage should be answered against the added coordinator tests (or resolved with that evidence), not left as an implicit waiver.

The prior guarded-target runtime checkpoint below remains historical; I did not repeat unchanged tests, authorize fork workflows, perform a live restart, alter your branch or approve this PR.


Historical checkpoint:
Verified the rework at 1ab7f56: handleProxyRestart retains the observed PID/port, passes them into runRestartUpdate, and wires stopGuarded to handleStop(approval), which revalidates under the ownership lease through runApprovedStop. The owning runtime and lifecycle docs now describe the transaction. I independently ran bun test tests/cli/restart-update-coordinator.test.ts tests/cli/system-restart-client.test.ts — 23 pass, 0 fail, 92 assertions, exit 0 on Linux/Bun 1.4.0, including A-to-B replacement and guarded-stop refusal without start. All stop/start/resolve/fetch boundaries were injected; no real service was touched. Execution used CPUQuota=75%, MemoryMax=1536M, swap disabled, fresh private homes, one workload. I dismissed my original resolved scoped change request. This is not a full-suite/typecheck/current-head CI pass or final independent boundary approval; attached successful gate jobs alone do not establish those. No security scan or live restart was performed.

The update restart stops the old proxy and then spawns process.execPath, which an
in-place npm install leaves as the bun placeholder until its postinstall. Refuse
before any stop byte while that runtime is incomplete (tracked in the transaction
because the stop transport sanitizes beforeStop errors), and after a confirmed stop
wait for it within the deadline, then recheck deadline and physical home
synchronously before the one launch. Same gate as the package-tree restart in #6569.

Carry #6548's user-facing explanations: announce the handoff and map each terminal
code to sanitized text that claims only what that phase proved.

* fix(cli): wait for a complete runtime around the update restart handoff

The update restart stops the old proxy and then spawns process.execPath, which an
in-place npm install leaves as the bun placeholder until its postinstall. Refuse
before any stop byte while that runtime is incomplete (tracked in the transaction
because the stop transport sanitizes beforeStop errors), and after a confirmed stop
wait for it within the deadline, then recheck deadline and physical home
synchronously before the one launch. Same gate as the package-tree restart in #6569.

Carry #6548's user-facing explanations: announce the handoff and map each terminal
code to sanitized text that claims only what that phase proved.

* test(cli): keep the proxied environment of the transport case in a child

Bun cannot unset an exported variable: delete process.env.X leaves it for later
spawns and for the next file in a --parallel worker. The HTTP-proxy interception
case set the proxy variables in the test process, so on macOS CI (BUN_TEST_PARALLEL=1)
the next file in the batch spawned ocx status through a closed proxy and the live
hub read reported unavailable. Run the stop in a child whose own environment
carries the proxy instead; the fixtures and assertions stay in the test process.

Closing as superseded by #6556 (merged into dev as 7cf1b76). #6556 covers the standalone upgrade restart when the CLI is newer than the proxy, verifying the exact replacement child, and carries this PR's progress and failure messages with Co-authored-by: agentHits. One part is intentionally not carried: restarting foreground or service-managed proxies, because the CLI cannot verify the replacement it would launch there. That path can be revisited in a new PR if there is a way to verify it. Thank you!

* fix(devin): retain bounded conversation trajectories (#6557)

Named Devin conversations retain an upstream trajectory across sequential turns and request-scoped adapters. Scope retained IDs by resolved credential, tenant host, and conversation; use fresh IDs for overlaps and when every retained slot is active. A 256-entry store evicts only inactive entries, and idempotent release in `finally` covers success, failure, and cancellation. The optional wire field preserves per-request allocation for unnamed calls.

Refines #6488 at `a0b199fc6b96367fb174f6488a7a45eb58eccd54`. Carries the optional #15.1 field, named continuity across adapters, unnamed fallback, overlap isolation, and failure release regressions. Replaces the source's map-plus-live-set with one bounded store, hashes a structured identity tuple, and prefers own-thread identity over a shared parent. Adds credential/host/alias/parent/cancellation/eviction/overflow/idempotence/retry coverage and documents the contract. The original author's live cache measurements are original source evidence; this replacement does not claim new measured savings. Independent of #6554; neither PR's runtime commits are required by the other. Coordinator owns source disposition.

* fix(claude): preserve bounded large headers in picker relay (#6551)

Claude Desktop picker HTTP relay rejects ordinary 24 KiB browser session headers at the runtime's default parser limit. Set a bounded 64 KiB allowance on incoming requests and ordinary upstream responses, preserving cookies and streamed body bytes. Oversized upstream headers still return an empty 502 with the fixed `upstream:headers-too-large` diagnostic.

Replacement for #6524 at `0c258acd496aef26735ab6a61d65cce611e8ff88`: carries both parser limits, fixed overflow diagnostic, all three regressions and both documentation changes. Adds inbound overflow and large-header streaming/upgrade coverage. No source behavior deliberately dropped. Raw upgraded transport remains unchanged; its upstream bytes do not use the ordinary HTTP response parser.

Related to #6511. No captured Desktop request proves large headers caused that issue; actual Desktop merged-chat/Cowork acceptance remains outstanding. This PR does not close it.

* fix(devin): qualify child trajectories by supplied parent (#6565)

Preserve supplied parent context when Devin selects an own-thread identity. Requests with the same own ID but different `x-codex-parent-thread-id` values now use distinct retained trajectories. Standalone and parent/own identities are both tagged structured values, preventing delimiter or JSON-like caller IDs from aliasing another identity form.

Follow-up to landed #6557 (`be297a52cd50766c54b571b82aeab45759fa6b65`), addressing [post-merge P1 review](https://github.com/lidge-jun/opencodex/pull/6557#discussion_r4176028586). The type comment distinguishes own from parent; this change does not claim it establishes global ID uniqueness. It fixes the concrete loss of a supplied parent qualifier. Source #6488 provenance remains `a0b199fc6b96367fb174f6488a7a45eb58eccd54`.

Standalone own precedence, explicit session-only behavior, credential/host isolation, overlap handling, cancellation/failure release and bounded retention remain covered. No installed-runtime or live provider calls. Coordinator owns merge and review-thread resolution.

* feat(anthropic): add native pool preference with explicit opt-out precedence (#6562)

Adds the Anthropic pool preference **Preserve native Claude requests**. Eligible pooled Anthropic routes default to native Messages only when the corresponding rollout flags are absent. Explicit false and malformed settings remain off; pool opt-out persists. Other providers retain their explicit policy.

Both settings APIs patch the latest persisted config. Unpublished failures roll back; confirmed publication with bookkeeping trouble adopts the saved setting and displays a warning; unknown outcomes require reload. Preview, token counting and runtime use the settled provider consistently.

Manual child of #6559, above #6552. Carries the remaining preference/API/GUI/default behavior from #6547 (`5f3cf4ed0b4a63604133863442002fb9ac824b16`). Its inherited native/tool behavior is covered by those parents. Deliberately corrects source precedence that overrode explicit false, malformed protocol recovery, nullable DTO normalization, stale-save-hook bypass, and publication-aware failure handling. Source disposition remains coordinator-owned.

* fix(chatgpt): say why a dropped chatgptDesktop block reads as off (#6486)

* fix(chatgpt): say why a dropped chatgptDesktop block reads as off

The read path degrades a `chatgptDesktop` block that fails the strict schema to absent. The app-
server shim then reads as off, `ocx chatgpt launch` refuses, and nothing says why, while the
file still reads `"appServerShim": true`. A key left over from an older or ported config, such as
`unblockSend`, is enough (#6196).

`chatgptDesktopConfigIssue` names the failing field. The config loader now warns with it like the
other top-level opt-in blocks, the config diagnostics list it, `ocx chatgpt status` shows it next
to the flag, and `ocx chatgpt launch` gives it as the reason it refuses. Writes still reject the
block as before.

* fix(chatgpt): explain a dropped chatgptDesktop block without loading the config validators

After merging dev, `ocx chatgpt` read the config file on every subcommand and pulled in all of
`leaf-validators.ts` for one helper. The bundle-trust command fixture from dev stubs the config
facade, so that import chain reached modules expecting the real facade and every scenario failed
to load. Restore scenarios would also have read this machine's own config.json.

- `chatgptDesktopSchema` and `chatgptDesktopConfigIssue` move to `src/config/schema/chatgpt-desktop.ts`,
  which needs only zod and the redactor. `leaf-validators.ts` re-exports both, so the schema and
  the load and diagnostics warnings are unchanged.
- The command reads the file only where it reports the reason: `status`, and a `launch` refused
  because the shim is off. `restore` and an enabled launch never touch it.
- The fixture stubs the config-file snapshot, and a new scenario checks that a refused launch
  names the failing field without quitting or opening the app.

* test(chatgpt): cover the status and launch messages for a dropped chatgptDesktop block

The command fixture now returns stdout. New scenarios: status names a dropped block next to the
off flag; status shows a plain off for a valid, absent or unreadable block; a refused launch with
no dropped block keeps the ordinary opt-in message. The first fails if status stops naming the
reason.

* test(chatgpt): name the config input in the plain-off status loop

* feat(service): name the holder when the runtime mutation lease is busy (#6512)

* feat(service): name the holder when the runtime mutation lease is busy

A supervised `ocx start` that times out on the runtime mutation lease used to say only
"another process owns the runtime mutation lease at <path>". Finding the holder meant decoding
the owner file in the lock directory by hand. Deleting the directory, the obvious shortcut, is
unsafe while the holder is alive. `ocx service status` meanwhile reported only that the proxy
was not running.

- The timeout error now names the holder from the record `readOwner()` already parses: the PID,
  whether it is alive, a live holder's executable name when `tasklist` (Windows) or `ps` answers
  within a second, and its age on the clock stale recovery uses. It also states the 30-second
  reclaim rule. An incomplete owner file is named by the PID in its file name. An empty or
  ambiguous lock directory says so. The holder is also on `error.holder`, with
  `error.code = "OWNERSHIP_MUTATION_LEASE_BUSY"`.
- `inspectOwnershipMutationLease` and `ownershipMutationLeaseStatusLine` read the same holder
  without reclaiming anything. `ocx service status` prints that line on every backend while the
  lease directory exists.

Closes #6492

* fix(service): report a lease freed mid-read as free, not as an unreadable holder

leaseHolder reads the lock directory in separate steps. When the holder released between them,
neither reader matched and the busy error said "holder unknown: the lock directory does not hold
exactly one owner file". It now re-checks the directory and reports no holder when it is gone.

* fix(oauth): release Anthropic refresh intent after a proven-unsent DNS failure (#6586)

* fix(oauth): release Anthropic refresh intent after a proven-unsent DNS failure

An Anthropic token refresh that failed DNS resolution before connecting left its
durable refresh intent behind, so the next attempt refused with
OAuthLoginRequiredError and the account needed a fresh login (#6570).

postJson now classifies a fetch rejection as unsent only when no outbound proxy
is configured and the error is a structured getaddrinfo ENOTFOUND for the token
host. The token exchange is pinned to one HTTP/1.1 attempt without keep-alive
reuse or redirect following, so that error cannot follow bytes already sent.
refreshAnthropicAccountWithLock releases that intent through the existing
generation-safe pre-dispatch cleanup. Timeouts, unstructured or wrong-host DNS
errors, body-read failures and proxied requests keep the replay guard.

* fix(oauth): keep the refresh intent on redirects and startup proxies

Security review follow-up. A 303 can follow a completed POST, so a 3xx from the
token endpoint is now an unknown outcome (no HTTP status) that keeps the
replay guard instead of a definitive rejection. Bun keeps the proxy it saw at
process start even after the environment changes, so the DNS release also
requires that no outbound proxy was configured at startup, captured once in
src/lib/proxy-env.ts before config mutates proxy keys.

The structured token-host DNS regression ran in the test process, so it
depended on how the runner was launched: startupOutboundProxyConfigured is
captured at module evaluation, and a runner started with HTTPS_PROXY correctly
keeps the intent while the case expected a release. The case now runs in a
child process launched with every outbound proxy key removed, sharing one spawn
helper with the startup-proxy cases, which keep running in a child started
with HTTPS_PROXY set.

* fix(combos): report the spent primary, not the fallback's own refusal (#6564)

* fix(combos): report the spent primary, not the fallback's own refusal

When every combo target fails, the client got the last target's error. A
spent Claude pool followed by an OpenAI fallback with no credential (401)
or a Free plan that cannot run the model (400) surfaced as 'OpenAI account
pool has no usable account credential' instead of the quota refusal.

Prefer the first 429/402 of the ladder over a later 400/401/403; when the
quota-refused target was already cooled before the request, answer with the
combo cooldown and its Retry-After.

* fix(combos): scope exhausted-combo 503 to quota cooldowns and align the logged child

Review follow-up. A pre-existing combo cooldown replaced a fallback 400/401/403
with 503 whatever caused it: a 502 cooldown or a cooldown on a target this
request could not pick turned a genuine credential refusal into a retryable
"no targets". Cooldown entries now keep their status, and only unexpired
429/402 cooldowns on targets the picker would otherwise consider (provider,
cached quota and request eligibility) count; the Retry-After comes from that
snapshot. Both exhaustion exits adopt the child log of the response actually
returned, so a returned 429/402 no longer carries the fallback's diagnostics.

* fix(combos): defer request eligibility to the exhaustion path

The pre-dispatch quota-cooldown snapshot evaluated request eligibility for every
usable target, which for native Chat combos built a translator-budget-charged
body per candidate even on a request with no cooldowns. The snapshot now reads
only 429/402 cooldown entries; eligibility is checked at exhaustion for those
cooled targets alone, and a throwing check counts as ineligible.

* fix(server): wait for a complete Bun before restarting onto a replaced package tree (#6569)

* fix(server): wait for a complete Bun before restarting onto a replaced package tree

- The package-tree fence treats a replacement whose process.execPath still fails REAL_BUN_MIN_BYTES like an unreadable tree: no restart, then a fresh full debounce once the runtime is ready. An in-place npm install writes package.json and the bun placeholder before its postinstall, so the restart spawned the placeholder (EUNKNOWN on Windows) and exited without a replacement

* docs(structure): record the fence's wait for the runtime it respawns

- The package-tree integrity fence section names the process.execPath gate beside the unreadable-manifest wait

* fix(server): pin the runtime path at boot and say when the restart waits for it

- createRuntimePackageTreeIntegrityGuard reads process.execPath once at construction, since Linux Bun resolves it lazily and reports a swapped-out binary as (deleted); an explicit runtimeReady: undefined no longer disables the gate

- The fence logs once when it starts waiting for the runtime, so a postinstall that never runs is visible

* docs(server): describe the package-tree integrity guard

- createPackageTreeIntegrityGuard names what it fences and when it hands a replacement to onReplaced, answering the CodeRabbit docstring check

* docs(server): qualify the guard's readiness guarantee

- The docstring says onReplaced waits on a configured runtimeReady check, since a direct caller may omit it; the installed-package guard always configures one

* docs(server): say the guard retries onReplaced after a throw

- The docstring no longer promises a single call: a throwing restart admission is rechecked and retried after another debounce while the replacement persists, as the existing retry test asserts

* fix(server): withdraw a settled replacement while its Bun runtime is incomplete

A replacement that settled before a failed restart admission kept reporting
installedVersion after the bun placeholder reappeared, so a manual restart could
pass the fenced readiness check before the runtime was complete. Clear the
settlement on entering the runtime wait, report no installed version while the
runtime is not ready, and reset the once-per-wait warning on baseline recovery.

* feat(gui): group the sidebar into eight rows and tidy the Claude surface (#6593)

* feat(gui): fold the sidebar into eight grouped rows and tidy the Claude surface

* fix(gui): keep focus when the section switcher hides under it

When Remote Workspace becomes unavailable while its switcher button has focus, only one member is left and App stops rendering the switcher, so the in-switcher recovery never ran and focus fell to <body>. The switcher now reports an orphaned focus on unmount and App moves it to the page's sidebar row, or to the main region when the row is off screen. Also renames a stale test fixture and fixes a stale test comment (review feedback).

* refactor(gui): hoist the switcher focus fallback to module scope

It reads no component state; react-doctor's prefer-module-scope-pure-function flagged it being rebuilt on every render.

* fix(gui): only hand switcher focus to a sidebar row that is on screen

Check vertical bounds too, keep the default focus outline on the main-region fallback, and assert the focus target in the orphaned-focus test (review feedback).

* fix(codex): keep Unix autostart shims off package-manager paths (carry of #6301) (#6589)

* fix(codex): keep Unix autostart shims off package-manager paths

On macOS and Linux, `ocx codex-shim install` no longer rewrites the codex
launcher that brew, npm, or fnm own. It publishes a private wrapper at
<OPENCODEX_HOME>/bin/codex and a sourceable codex-shell-env.sh that puts that
directory first on PATH, so package-manager upgrades and version rollbacks keep
working without rewrapping. Shell startup files are never edited.

- schema-2 shim state records the wrapper, native launcher, and the inode
  identities of the private files; state is the commit marker of a journaled
  publication, and failures roll the private files back
- an older in-place Unix shim migrates on explicit install: the recorded
  backup is restored without replacing a newer native entry, and ambiguous
  layouts refuse and keep every artifact
- automatic repair refreshes only owned private files under the existing
  opt-in; status and doctor no longer trigger repair; identity-less or
  unsafe (group/world-writable, replaced) artifacts are preserved and reported
- diagnostics separate runnable from active; install succeeds when the wrapper
  is runnable and prints the activation command; connect and doctor report an
  inactive overlay with that guidance
- PATH activation uses the shared scanner with #6493's executable-bit rule;
  runtime, catalog, and feature probes prefer the validated native launcher
- Windows keeps its in-place wrapping unchanged
- diagnostics move to shim-diagnostics.ts so shim.ts shrinks below its cap

Carries #6301 onto current dev. The PATH-readiness test fixtures are taken
verbatim from #6493.

* fix(codex): revalidate overlay artifacts before reporting healthy

Diagnosis, automatic repair, and the already-installed install path now
re-snapshot the state, wrapper, and shell environment right before they
report healthy or print the activation command, and refuse when identity,
bytes, mode, or ownership changed during the native or PATH inspection.
The Unix destruction regression now replaces only the native launcher,
which is what a version manager owns behind the private overlay.

* fix(codex): let a migration retry after a failed journal write

Explicit install creates codex-shim.migration.json before it moves anything.
If writing it failed part-way (ENOSPC, EIO) or the path was replaced, the
empty or truncated journal stayed behind, and every later install refused on
the unreadable record. Nothing has moved at that point, so the run now
removes the journal it created, but only while the path still names the
descriptor's own inode. A replaced journal and every native and recovery
artifact are left alone.

Regressions cover a partial ENOSPC write followed by a successful retry and a
journal replaced during creation that must survive.

* fix(integrations): write DSH routes to the Desktop profile patch it reads (#6522)

* fix(integrations): write DSH routes to the Desktop profile patch it reads

DSH 0.1.7+ imports $DSH_HOME/settings.yaml once into the first profile
that boots and renames it to settings.yaml.imported. From then on it reads
provider routes from the llm-pi-ai row of a profile patch (a top-level
YAML list of loader rows) and hot reloads that file. The integration kept
writing settings.yaml, so after that first import a catalog refresh, a
model change or a disable reached nobody, and status read the renamed file
as absent.

Declare the Desktop profile's cordis.patch.yml as DSH's currentStore (the
seam from #5348), addressed through a leading [id=llm-pi-ai] selector.
The home patch is not an alternative: a home row replaces the profile
row's whole config, the user's own routes with it.

- merge.ts keeps a sequence root, and prunes an element it seeded once
  only its selector fields remain.
- The source-preserving YAML patcher edits one top-level list entry as the
  block map it holds and restores its "- " and two-space indent byte for
  byte. DSH's empty `[]` is the only flow form adopted, and a disable that
  empties the list writes it back.
- IntegrationTarget carries its own sourcePreservingYaml, so the legacy
  file and the store are patched along their own paths, and a coordinated
  write also holds DSH's config-editor lock (the profile's
  package.json.lock) whenever the profile directory exists.
- Without a Desktop profile the legacy settings.yaml stays the target.
- The dashboard accepts the new plan path; GUI text, docs and the
  integrations structure doc describe the new location.

* test(gui): pin the DSH ownership copy to the Desktop profile path

The locale-parity fixture still held the settings.yaml sentence in every
locale, and the DSH surface test asserted the old llm-pi-ai.providers
spelling. Both now follow the copy: the llm-pi-ai row, the Desktop
profile patch, and the settings.yaml fallback.

* fix(integrations): keep DSH profile refresh order and lock late profiles

Refreshing a Desktop profile row that OpenCodex created no longer deletes and
re-appends it in the expected merge, so a row DSH appended afterwards no longer
turns a routine catalog refresh into an "unsafe" refusal. The created-row
provenance is kept so disable still removes it.

The profile manifest lock is now chosen after the settings lock is held and
re-checked after every revalidation await, so a profile that appears mid-write
is locked and revalidated before it is read or written. Removing the last
managed row also keeps the file's original final-newline and CRLF convention.

* fix(integrations): refuse restoring into a missing DSH profile directory

A confirmed restore of a journaled Desktop profile write used to recreate a
removed profiles/desktop directory and write it without the profile's
package.json.lock. Preview and restore now refuse as unsafe when the declared
locked store's directory is missing, and the structure doc records the lock
re-probe, row-order, and restore contracts.

* docs(structure): fit the DSH store paragraph inside the integrations budget

Merging #6577 put structure/clients/integrations.md four lines over its
600-line budget. Tighten the DSH paragraph without dropping any contract.

* fix(integrations): report a booted DSH profile without a patch instead of writing settings.yaml

With profiles/desktop/package.json present and cordis.patch.yml missing,
the target fell back to $DSH_HOME/settings.yaml with no ineffective
marker. DSH imported that file when it booted the profile and never
reads it again, so the write was lost without a word. A store
declaration can now name a missing store the client still reads; DSH's
does, and the write is refused as an ineffective one with the remedy
(create the patch as `[]`).

* docs(integrations): state why a DSH profile without a patch is refused

The comments, structure doc, and refusal message said DSH imports
settings.yaml once and never reads it again. Upstream DSH's
importLegacyDocument renames settings.yaml to settings.yaml.imported and
imports it on every startup where it exists. The refusal stays: a block
written there would be moved out from under opencodex's ownership record.
Only wording changes; behavior and tests' assertions are unchanged.

* fix(cli): accept the DSH profile-patch plan path from refreshed dev

Dev (#6522) publishes DSH routes through the [id=llm-pi-ai].config.providers.opencodex template of the Desktop profile patch and added it to the GUI plan decoder. The CLI closed decoder mirrors that list, so every DSH preview was rejected as invalid; tests/cli/cli-integration-preview.test.ts caught the drift.

* test(oauth): make the startup-proxy refresh test hold on Windows (#6600)

* test(oauth): remove proxy keys case-insensitively in startup-proxy children

The startup-proxy refresh cases failed on Windows (dev dadc2328f1, CI run
37227252582, shard 6/9): after the child deleted the six fixed proxy key
spellings, outboundProxyConfigured() still returned true. Windows environment
names are case-insensitive, so an inherited spelling outside that fixed list
survives. Both the parent env handed to the child and the child's own cleanup
now remove every key whose upper-cased name is HTTPS_PROXY, HTTP_PROXY or
ALL_PROXY, and the precondition assertion names any proxy key still visible.
The production startup-proxy guard is unchanged.

* test(oauth): only require an observably proxy-free env where deletion is observable

Windows CI run 37229867142 showed the real cause of the shard 6/9 failure: on
win32 Bun 1.4.0, deleting a process.env variable removes it from enumeration
(no proxy key remains in Object.keys(process.env)), but property reads still
return its value, so outboundProxyConfigured() stays true. The "deleted" child
therefore keeps its strict current-env precondition on every other platform,
and the "empty" child keeps it everywhere. The startup snapshot and intent
retention assertions run on all platforms. Production behavior is unchanged;
on Windows a runtime deletion simply leaves the guard closed.

* test: make catalog audit and provider proxy fixture robust on Windows; state unhealthy in-place shim status (#6602)

* test: make catalog audit and provider proxy fixture robust on Windows runners

Compare the audit opencodexHome with redactUserPath of the same path, so long, 8.3 and non-home temp roots all hold. Fail only the audit file ACL in the Windows audit privacy cases; the catalog writer legitimately hardens its own backup on real Windows. Bound the provider proxy fixture child at 45s on Windows (12s elsewhere) under a deadline 3s above it, and report signal, elapsed time and bound when it is killed.

* fix(codex): state the unhealthy verdict in in-place shim status

diagnoseCodexShim computed healthy:false for a damaged Windows in-place wrapper, but its summary only said "shim present", so ocx codex-shim status read a broken wrapper as fine. Append the unhealthy verdict and repair command when the diagnosis is unhealthy, matching the overlay summary. A host-independent regression records a legacy win32 in-place state; it fails without the fix.

A DSH Desktop profile whose cordis.patch.yml is missing is refused as
superseded_store, and the CLI names the fix: create the patch containing
`[]`. The dashboard only had the generic superseded-store copy, which says
the client reads a file opencodex does not write and offers no way out.

- The missingStore declaration publishes its empty document (`[]` for DSH)
  beside the remedy text, and IneffectiveWrite carries it.
- Status rows carry supersededReason beside supersededBy, plus
  missingStoreDocument for a missing store.
- A superseded_store plan carries the same two fields. The plan still names
  no file (the path stays on the status row), and the fingerprint does not
  change: the bound ineffective-write token already covers this finding.
- The GUI accepts the fields only on a superseded_store refusal, the
  document only for missing-store and only as one short line, and renders
  copy that names the file and the document in all eleven locales.

* fix(integrations): name the missing store in the dialog and decode it in the CLI

- The apply dialog covers the page's status notice, so a refused DSH
  preview now names the patch path as well as `[]`. The path comes from
  the status row; the plan still names no file. Bulk dialogs, which have
  no single status row, keep the pathless copy.
- The Turkish copy names the legacy settings file explicitly instead of
  "that file".
- The CLI plan decoder from #6542 accepts supersededReason and
  missingStoreDocument under the same contract as the GUI, and
  `ocx integration client preview` prints the remedy. Both decoders now
  reject a non-string reason and a document that is not one short
  printable-ASCII line, since the CLI echoes it to a terminal.

* fix(gui): keep short sidebars, Claude sidecar rows and Save errors usable; open legacy #debug on Debug

Audit follow-up for the GUI merged since v2.77.0 (#6579, #6593, #6596):

- A short or zoomed desktop window no longer collapses the sidebar menu to its padding: the menu keeps about three rows and the whole rail scrolls only when it cannot fit, with the language menu kept on screen.
- The Claude web search and vision sidecar rows wrap their controls under the copy instead of covering the title (French at 768px) or clipping the model input (390px).
- A failed Save on the one-page Claude settings reports in the Save bar, where it was clicked; the bar status wraps instead of sliding under Revert.
- Cold-loading a legacy #debug bookmark selects the Debug tab, reading the canonical hash like Connect and Providers do.

Findings and plan: devlog/_plan/261005_r4_gui_audit/.

* fix(gui): keep the short-window language menu on screen in every engine

Review on #6612: the rail backdrop-filter makes the sidebar the containing block of the fixed language menu, so an engine that treats it like an absolute child would scroll and clip it with the rail. In windows 480px tall or less the rail is now opaque, as in the existing no-backdrop-filter fallback, which anchors the menu to the window; the menu is opaque too.

English and the seven translations now match the shipped dashboard.

* docs: name the DSH missing-patch refusal and finish the Connect → API Keys rename

Review on #6613: a Desktop profile without cordis.patch.yml makes Apply refuse with the create-[] remedy rather than write the patch or fall back to settings.yaml, and the remote-hub, CLI lifecycle and Codex integration pages still pointed at Integrations → API Keys or the Integrations overview.

* fix(test): keep armed test processes out of the real Codex home (#6591)

* fix(test): keep armed test processes out of the real Codex home

A local suite run rewrote the real ~/.codex catalog twice (#6529): a
convergence ran with OPENCODEX_HOME in the test temp tree and
CODEX_HOME unset, so it resolved os.homedir()/.codex, which ignores
the preload's HOME on macOS. The real-home guard covered the OpenCodex
home and native auth.json, not the catalog, models cache, journal or
config.toml.

atomicWriteFile now refuses any write whose directory is the real Codex
home in an armed test process, and K refuses it before the owner
precheck, so a test never gets a catalog permit for it.

Refs #6529

* test: probe the unset-CODEX_HOME fallback against the real-home guard

Run the probe child with CODEX_HOME absent and HOME/USERPROFILE at the
sentinel home, check getCodexHome() resolves there, and check every
Codex-home write and K are refused. This is the path the incident took.

* fix(claude): serve the Desktop picker over HTTP/2 so SSE streams cannot starve claude.ai (#6511) (#6610)

* fix(claude): serve the Desktop picker over HTTP/2 so SSE streams cannot starve claude.ai (#6511)

The picker listener terminated claude.ai with an HTTP/1.1-only TLS server.
Claude Desktop keeps several messages/stream SSE subscriptions open, each
holding one of Chromium's six per-origin HTTP/1.1 connections, so later
claude.ai requests queued in the client and timed out before reaching
OpenCodex. Blind tunnels negotiate HTTP/2 with Anthropic and multiplex.

The listener port is now a TCP front that reads the TLS ClientHello ALPN
offer (bounded multi-record reassembly) and splices the untouched
connection to an HTTP/2 server when the client offers h2, or to the
existing native HTTP/1.1 relay otherwise (WebSockets included). HTTP/2
requests are translated for the HTTP/1.1 upstream (:authority -> Host,
cookie crumbs joined) and cancellation follows the underlying stream.
Shutdown force-closes every front, bridge, h2 and HTTP/1.1 socket.

* fix(claude): bound picker h2 fan-out and refuse unrelayable h2 targets

Security review of #6610: an HTTP/2 :method or :path that the HTTP/1.1
client cannot express threw before cleanup was installed, and one
connection could open unbounded streams, each dialing upstream. Validate
h2 targets and guard request construction (empty 400, fixed log line),
advertise maxConcurrentStreams 100 per session and cap in-flight upstream
requests at 256 listener-wide (empty 503 without dialing).

* fix(claude): refuse picker targets the URL parser rejects

Security re-review of #6610: an origin-form h2 path such as //[ passed
the target check but threw in new URL() before the refusal boundary.
Parse the pathname inside it and answer an empty 400.

* fix(claude): do not log a client-cancelled picker request as 502

Hosted CI on #6610: cancelling an h2 HEAD before upstream headers closed
upstream as intended, but the teardown error then wrote a 502 log line
for a client that had already gone. Ignore upstream errors once the
client side closed first. The ALPN test now asserts only that HTTP/1.1
clients never get h2: Bun's native HTTP/1.1 server does not report its
ALPN choice.

* fix(cli): stop echoing values in claude desktop apply argument errors (#6618)

* fix(cli): stop echoing values in claude desktop apply argument errors

parseDesktopApplyArgs printed unknown arguments verbatim, so an inline
--token=<value> or a stray credential operand reached the terminal.
Show options by name only and bare operands as <redacted>.

* fix(cli): never echo rejected claude desktop arguments

Security review of #6618: option names can still carry values (-tVALUE,
dash-prefixed operands) and control characters. Apply errors now count
unknown arguments and list the valid options; move/default show a route
operand only when it is a plain provider/model id.

* fix(cli): keep desktop bind and profile file errors free of operands

Security re-review of #6618: bind errors echoed a rejected picker id and
an unavailable route, and import/export printed filesystem errors that
carry the user-supplied path. Binding errors now omit the id and show a
route only as a plain provider/model id; profile file failures report
the operation and error code.

* fix(cli): drop rejected route operands from desktop errors

Security re-review of #6618: a route that only looks like provider/model
is still a rejected operand. move/default and bind now say the route is
unavailable and point to ocx claude desktop show, without echoing it.

* fix(gui): keep Claude Desktop role selects inside the Models card (#6625)

* fix(gui): keep Claude Desktop role selects inside the Models card

A long unavailable stored model plus its status overflowed the role
select at 390px (chevron and status clipped) and squeezed the label
column to nothing at 768px. Bound the controls column, let the route
truncate inside the trigger while the translated status and chevron
stay whole, and put the full text in the trigger tooltip.

* test(gui): cover the unavailable role choice label and tooltip

The route sits in its own truncating span, the translated status in a
separate element, and the trigger's tooltip carries the full text.

* fix(gui): integration dialog starts on Close; client status failure offers Retry (#6623)

* fix(gui): start the integration dialog on Close and offer Retry when client status fails

Found by the R4 audit of #6597: showModal() focused the invisible backdrop dismiss button, so the dialog opened with no visible focus and Space dismissed it unseen; and a cold status-load failure on a client page had no way to retry.
