Summary

Maintainer-controlled promotion of dev to the preview prerelease train. preview was 29 commits behind; this brings the current integration line over, headed by the Codex model-picker incident fix in #4531.

The incident: on Codex 0.154.0-alpha.6.2 a paginated-history preflight vetoed the entire Codex config write, so model_catalog_json never reached config.toml and both the Codex app and the CLI fell back to their six built-in models, while ocx sync reported the failure as success. The fix scopes that refusal to the conversation-history relabel unit on the apply direction only.

A routed Responses destination could receive a private `agent_message` item
together with ChatGPT-backend ciphertext. Two checks bounded that item and
neither covered the gap between them: `hasUnreadableEncryptedAgentTask` asks
whether the current worker task is readable and inspects only the tail item,
while `normalizeRoutedAgentMessages` asks whether every content part can be
lowered onto a public message and forwards the item verbatim when one cannot.
An item mixing `input_text` with `encrypted_content` answers "readable" to the
first and "not lowerable" to the second, so it passed the guard and reached the
provider as ciphertext plus an item type only the Codex backend declares. xAI
answered `422 unknown item type "agent_message"` after the bytes were sent.

`agentMessageCiphertextIndex` asks the egress question over the whole expanded
input, and the request path asks it against the final route, after recovery has
had its chance to replace the ciphertext with plaintext. A hit returns HTTP 400
`unforwardable_encrypted_agent_message` with the item index and nothing else
from the item. The gate resolves the same wire override the adapter is built
from, so it fires only for the raw Responses passthrough on a non-forward
destination; translated wires, forward destinations and routes explicitly
trusted with `allowEncryptedV2AgentTasks` are unchanged, as is the tail NEW_TASK
envelope and its opt-in recovery.

Reported by @321sssrt-bit.
Intersect explicit custom reasoning lists with pinned native metadata whenever
the model id itself is capability-backed, including YYLJ/gpt-6-astra. Desktop
validates the model id, so none/minimal must not remain on those catalog rows.

Full native identity still requires the canonical openai Codex-forward
destination. Stored configuration and request-time clamps are unchanged.

Refs #3775. Original report by @leonclab. #3804 already bounded the canonical
forward case; this is the remaining catalog projection.
Remove deepseek-flash from first-party DeepSeek noVisionModels and declare
native text and image input in modelInputModalities. Compatibility aliases
and Zen gateway routes stay on the sidecar path.

This uses the existing registry seed contract (modelInputModalities and
noVisionModels). Eligibility already consults user-config modelCapabilities
first; the registry does not seed that overlay.

Refs #4436.

…try seeds

The #4467 carry dropped deepseek-flash from first-party noVisionModels. Update
the minimal persisted-config route assertion so it matches the new seed instead
of issue #88's text-only list.

Refs #4436.
The 400 this replaces was wrong. CI caught it: `responses-opaque-blob-recovery`
proves the project already repairs this shape, reactively — an undecryptable
part becomes `[encrypted content omitted]`, which leaves the item lowerable —
and failing the request closed killed that recovery instead of completing it.

A destination that cannot accept the private item under any circumstances was
never going to answer the request, so the round trip only served to send the
ciphertext. Apply the same repair before dispatch instead: the provider never
sees the ciphertext or the private item, the readable half of the item survives,
and the conversation continues rather than ending on a 400.

Only backend-minted Fernet ciphertext qualifies, in an encrypted slot, split
across consecutive slots, or embedded in text or string content. Every other
opaque payload keeps the reactive opaque-blob recovery, which can still rescue a
destination that merely failed to decrypt something it was entitled to read —
that distinction is what keeps the existing recovery suite meaningful. Combo
attempts are excluded because their targets share one body object and a native
target in the same combo can still read what this would erase.
chore(release): open dev at 2.54.0 before releasing 2.53.0
…epseek-flash-vision

Lane I3 of the contributor carry train: the remaining #3775 catalog defect, and the deepseek-flash native-multimodal fix carried from #4467 by jaychou0642-create.

#4467 was found by the dispatch-time ownership re-check rather than by the candidate harvest — it was opened after the harvest and before this lane, by the person who filed #4436 — so it is carried with a Co-authored-by trailer instead of being reimplemented. That check exists because lane I1 implemented #4442 fresh while contributor draft #4465 had already proposed it.

The #3775 link is an implementation with no source branch. It bounds custom native-id effort lists on gateways, which is what #3804 deliberately left open pending Desktop gateway evidence; the original report is that evidence, since Desktop names gpt-6-astra in the 400 rather than the provider prefix. #4349 and the #4409 ladders do not fix this catalog projection.

Cross-platform CI run 34751593123 concluded success on 9f318cb, the exact head merged here, and it covers both links because the lane is cumulative. #4499 carries no ci check of its own under the owner-authorized tip-only CI economy for this batch.
Four maintainer review findings, two of them the same class of defect as the
one this branch fixes.

Combo children were skipped, on the belief that combo targets share one body
object. They do not: concreteComboRequestBody structuredClones the body per
target, so a sibling's repair is invisible to a child and a target resolving to
a routed Responses wire still sent Fernet. Children now run the repair on their
own clone, against their own concrete route.

The matcher failed open on near-miss ciphertext. Requiring a canonical Fernet
token meant a truncated token, a standard-base64 blob carrying + or /, an
unexpected version byte, a run split across slots, or a run past the 32-part or
2 MiB recovery limits each kept the item and forwarded the bytes — the original
#4454 path reached by a slightly different payload. Every encrypted_content slot
in an item the adapter cannot lower is now treated as ciphertext, and free text
is judged by the same looksLikeBackendCiphertext heuristic the sanitizer already
trusts. Whether ChatGPT ever emits non-urlsafe or non-Fernet agent-task
ciphertext no longer has to be answered.

The exemption was authMode === "forward", which describes how this proxy treats
credentials rather than who answers. A noncanonical forward gateway is somebody
else's server and received the ciphertext. Only isCanonicalOpenAiForwardProvider
is exempt now, since it alone minted these bytes and can read them.

Tests for the two claimed matcher shapes that had none — a run split across
consecutive encrypted slots, and a token embedded in a text part — plus the
combo child, the noncanonical forward gateway, and three near-miss blobs.

The widened matcher reaches the opaque-blob suite's agent-message fixture, which
is Fernet-shaped but not structurally valid. Its two agent-message tests now
assert the pre-dispatch repair and that no blob appears in any outbound body;
the five that used that fixture as a vehicle for error-event, flat-error and
repeated-failure machinery move to the function-output fixture, which still
carries a blob and still exercises the reactive path.
…coverage

Round three. The widened matcher fixed one direction and broke the other: it
judged free text by looksLikeBackendCiphertext, which is length >= 64 over a
character class that a SHA-256 digest matches exactly at 64 characters. A
SHA-512 digest, a long key, and adjacent short encoded fragments joined to 64 or
more matched too, so a child that printed any of them had it replaced with
[encrypted content omitted] while the docs claimed nothing readable was lost.

The asymmetry is the fix, as review pointed out. An encrypted_content slot holds
ciphertext by definition and keeps the always-strip behavior. A text part does
not, so it is matched strictly: embedded runs that validate as Fernet, or a whole
slot with the Fernet wire shape -- g prefix, base64url alphabet, length at least
100 and divisible by four. Adjacent fragments are joined before that test, so a
token split across text slots is still caught, while two ordinary encoded
fragments no longer become a marker by being adjacent. A 64-character hex digest,
a SHA-512 digest and an sk-proj key now survive, with a test each.

Coverage, fixed rather than recorded. prepareOpaqueBlobRecovery's agent_message
arm is unreachable for non-canonical destinations by construction but still live
for the canonical Codex backend, which is the one that minted the bytes and so is
the one that can fail to decrypt them. Two integration tests now exercise it
there and restore both assertions the fixture migration dropped: recoveryKinds
containing opaque-blob-rejection on the JSON path, and a streamed decrypt failure
staying hidden from the client. They also pin the exemption itself -- the blob
reaches that destination on the first send and only the post-rejection repair
takes it back off the wire.
…gent-message-egress

Lane I4 of the contributor carry train, released from its security-review hold.

Fixes #4454 (reported by 321sssrt-bit): a routed Responses destination could receive Codex's private agent_message item together with ChatGPT-backend ciphertext and reject the whole request. Two checks bounded that item and neither covered the gap between them — hasUnreadableEncryptedAgentTask inspects only the tail and reports readable as soon as any plaintext survives, while normalizeRoutedAgentMessages forwards the private item verbatim when a part cannot be lowered. An item mixing input_text with encrypted_content answered readable to the first and not-lowerable to the second. stripAgentMessageCiphertextInPlace now applies the existing repair before dispatch instead of reactively after a 422.

Maintainer security review took three rounds and each one changed the code. Round one found that combo children bypassed the repair on their own structuredClone, that the matcher required a canonical Fernet token so near-miss ciphertext fell straight back into the original defect, and that exempting authMode === "forward" handed the ciphertext to any noncanonical forward gateway. Round two confirmed those closed but found the widened matcher had traded fail-open for data loss: looksLikeBackendCiphertext is length >= 64 over a character class that a SHA-256 digest matches exactly, so a digest a child deliberately printed would have been replaced with a marker.

The landed shape keeps the two slot kinds asymmetric, which is what makes both halves correct. An encrypted_content slot carries ciphertext by definition and is stripped whatever it holds. A text part carries no such guarantee and is matched strictly: embedded runs that validate as Fernet, or a whole slot with the Fernet wire shape. The canonical Codex backend still receives the private item and its ciphertext verbatim, since it is the only destination that minted those bytes and can read them.

Round three also restored the two canonical-path assertions an earlier fixture migration had dropped, so the reactive agent_message recovery arm is covered at integration level again rather than at unit level only.

Cross-platform CI run 34754905195 concluded success on 0226c07, the exact head merged here.

No Co-authored-by trailer: this is an ordinary implementation with no contributor branch behind it, and the reporter is credited in the pull request description.
Plan the carry of the 16 open contributor pull requests scored 60 or higher and
the 8 unowned 60+ issues into dev, as eight wave-1 lanes and three wave-2 lanes.

Two grok-4.6 reviewer passes gated this roadmap. The first returned FAIL on five
blockers: H and I4 were prepared as peers though both write the routed Responses
path, #4447 carried a security-review hold in one document while another
tip-merged the lane containing it, lane I1 claimed a Windows CI leg that is
workflow_dispatch-only, the core.ts toucher count called an issue a pull request,
and the candidate table omitted #4409. All five are folded here; the second pass
returned NEAR-PASS and its three wording residuals are folded too.
Seven of eight wave-1 lanes are on dev; lane S stays green and unmerged pending
security review. Records the credit defect the wave surfaced: contributor draft
#4465 proposed the #4442 fix after the candidate harvest and before the lane, so
the I1 landing carries a Co-authored-by trailer for its author. Also records the
two planned carries that were already satisfied on dev, both found by attempting
the work rather than by reading the plan.
All eight wave-1 lanes are on dev. Records why the security hold was worth
having: the review found that the canonical OpenAI seed defines only four keys,
so overlay tolerance reached headers, which the PATCH mask writes and the forward
adapter applies to the upstream ChatGPT request ahead of incoming headers. The
fix denies headers on canonical openai and adds the regression that was missing.
#4436 has an owning contributor pull request, #4467 by jaychou0642-create, opened
after the candidate harvest and before this lane. Lane I3 carries it with a
trailer instead of implementing the fix fresh. This is the wave-1 #4465 lesson
applied as a dispatch-time check rather than a note.
#3663 was already on dev as a33b51e via #4360, carried from the same head with
both trailers intact, so the lane had nothing to carry. It also disproved the
predicted core.ts conflict: I4's strip and the context-history ownership
recording are gated on complementary destination predicates and sit on opposite
sides of dispatch. Third planned carry in this train found already satisfied on
dev, after #4170 and #4086.
…work

#4077 proposed opening the Grok OAuth lane to service_tier priority and
correcting the Fast-tier catalog copy. The registry half landed independently
through #4431 with a narrower, live-probed scope and no reference to the
proposal; the copy correction landed later through #4474 with a trailer. The
first half is recorded as an acknowledgement rather than as carried code.

Also records the gate's false-positive mode: a description that merely talks
about a carry train fails missing_coauthor_credit even with no source author,
which #4499 hit. Writing around it is cheaper than loosening the matcher.
Eleven lanes landed, one needed nothing. Records what every audit round caught —
the roadmap failing on two lanes prepared as peers that both write
responses/core.ts, the packets failing on an unqualified "never merge" that would
have blocked the required dev re-merge, lane S on a headers overlay that reached
the upstream ChatGPT request, and lane I4 on the same defect wearing three
different payloads.

The lesson that repeated in both directions: three planned carries were already
on dev, and two contributor pull requests were opened after the inventory
snapshot. Neither is fixable with a better inventory; only the lane touching the
code can tell.
Key-auth Responses gateways could opt into webSearchBridge, but only the
Ollama executor shipped, so a non-ollama.com origin never armed. Reuse the
existing sidecar executors behind an explicit backend, keep mixed-tool and
assistant-text dispatch fail-closed, and leave continuation redesign out of
this slice.
The wire layer was already multimodal: ChatMessagePrompt field 10 encodes
ImageData {base64_data, mime_type, caption}, verified against extension.js.
The adapter mapping discarded every image.

textFromParts extracted only type:"text" parts and returned a string, so an
image contributed an empty fragment. mapOneMessage then dropped any message
whose extracted text was empty, which means a pasted screenshot with no
caption killed the turn at 0s — the message vanished before the model saw
anything, and the only workaround was running tesseract before sending.
toolResultText did the same to tool-result images.

Convert content at the boundary instead. A data: URL has everything
field 10 needs, so it parses into {mimeType, base64Data}. A remote https
URL cannot be inlined without a fetch and stays as an explicit text
reference rather than pretending the model can see a picture it cannot.
Video has no Devin field and is skipped. An error tool result keeps its
ERROR prefix alongside the images.

The dead toolResultText is removed.

Local product tests, typecheck, build and install: NOT RUN.
Hosted exact-head CI on this PR is the merge proof.
Records the contributor carry train: the roadmap, how the candidate inventory was collected, the wave outcomes, and the disposition map. Also records in CREDITS.md a proposal that independent work overtook, and the hygiene gate's false-positive mode.

Docs only. Cross-platform CI run 34758662175 concluded success on f0eb40e, the exact head merged here.

Lane I5 was still in flight when the outcome document was written, and the document says so rather than claiming a finished state.
Importing sidecar locators from web-search/index.ts left findAnthropicSidecarProvider
uninitialized when core loaded the barrel and the bridge together. Move the locators
to a sibling module and capture Exa search headers so the non-Ollama credential
path is pinned in the fixture.
…restart-codex (#4510)

* docs(devlog): roadmap for the cross-platform Codex desktop-app restart

Measured the desktop-app topology on macOS, Linux and Windows and recorded why
`ocx sync --restart-codex` appears to do nothing: the app-server it signals is a
child of the desktop app, which respawns it while the picker keeps the roster the
shell built at launch.

Plans folding --restart-desktop-app into --restart-codex on every platform, a
shared restart surface with three adapters, a detached self-handoff for the case
where the caller runs inside the app, and the live three-host proof.

* docs(devlog): fold the A-phase audit blockers into the restart roadmap

Three independent audits ran against the roadmap before implementation; two
returned FAIL. Folds all six blockers: the ancestry walk now fails closed when it
hits its hop bound while treating a dead parent as clean chain-end, concurrent
restarts take an atomic singleton lock, membership compares realpath-resolved roots
with a trailing separator, catalog pull joins the merged flag contract, the remote
machine-sync restartCodex field keeps app-server-only meaning, and the post-write
helper returns its outcome so the catalog envelope can be derived from it.

* docs(devlog): transfer the restart lock to the handoff helper instead of contending for it

Taking the lock on the direct path and then requiring it again in the helper that
path spawns would deadlock every self-handoff restart. The caller now rewrites the
lock owner to the helper pid after a successful spawn and exits without releasing,
so the helper inherits ownership and a concurrent caller still sees restart_in_flight.

* docs(devlog): give restart_in_flight a contract home and stop the service promising a handoff it cannot keep

The re-audit confirmed all six original blockers closed and found two more. The
singleton lock is now taken by restartCodexDesktopApp itself and restart_in_flight
joins the reason union, so the exhaustive switch, the catalog envelope and the
management summary all have a defined path for an outcome the design guarantees.

The management service passes allowHandoff: false: it runs inside a proxy that never
exits, so a handoff built on waiting for the caller to exit would always time out
after telling the operator it had been handed off. It refuses with an actionable
message instead. Measured locally, the service proxy runs under launchd outside the
app tree, so the direct path is the normal one.

* docs(devlog): name the lock reentrancy rule and the test-only evidence scope

* docs(devlog): record the roadmap unit's resume state and wp2 direction

* feat(codex): make the desktop-app restart a cross-platform shared surface

restartCodexDesktopApp was Windows-only and returned windows_only everywhere
else, so macOS and Linux had no way to refresh a stale model picker at all. The
module body is now a platform-independent ladder over three adapters behind
DesktopAppAdapter, because the interesting part - fail-closed probing, PID-reuse
re-verification, root selection, ancestry - is identical everywhere and only
identity, discovery, membership, the two stop primitives and relaunch differ.

macOS discovers the bundle the running shell executes out of, confirms
CFBundleIdentifier is com.openai.codex rather than trusting the ChatGPT.app name,
quits with the Apple event and relaunches with open -b. Linux resolves the
package launcher to a root it requires to be uid 0 and not group- or
world-writable, enumerates through /proc, and relaunches detached under setsid
carrying the graphical session forward. Windows is the existing Appx/CIM/taskkill
implementation moved across unchanged in behaviour.

Three things the measurements changed. Root selection now requires the process to
be the app shell, not merely a member whose parent is outside the tree: macOS
crashpad handlers sit at ppid 1 and stale ones outlive the instance that spawned
them, so the old rule would have signalled them and let a survivor block every
relaunch. The Linux relaunch environment is read from a child rather than the
root, because the root zeroes its own environ block after startup - measured as
1902 NUL bytes - and only children still carry XDG_RUNTIME_DIR. And the ancestry
walk now distinguishes a dead parent, which is a clean end of chain and the
normal state of an orphaned helper on Windows, from a hop it could not read or a
bound it hit, both of which fail closed.

relaunch_failed is a new reason. A failed relaunch previously reported
targets_survived with an empty surviving list, which sent operators looking for
processes that had in fact all exited.

A singleton lock makes a restart that acts exclusive. Two concurrent ladders are
destructive rather than wasteful: the second re-enumerates during the first's
relaunch, sees the freshly started shell as a target, and kills it.

Plan, measurements and three rounds of audit:
devlog/_plan/260913_cross_platform_desktop_app_restart/

* fix(codex): close three fail-open defects in the desktop-restart surface

An independent audit of the new surface found that the safety contract in the
plan was not actually implemented in three places.

The dangerous one was Linux ancestry. An unreadable /proc/<pid>/status returned
the chain collected so far, so a failure on the very first hop produced
[process.pid] - a non-empty chain that does not intersect the app tree. The
ladder reads that as "outside the tree" and signals, which means a probe failure
would have quit the desktop app hosting the caller's own session. ENOENT now ends
the chain cleanly because the pid is genuinely gone; every other error returns []
and fails closed, and hop 0 is always treated as a real failure because that pid
is this process.

macOS had the opposite defect. ps -p <pid> exits 1 for a pid that does not exist
and execFileSync turns a non-zero exit into a throw, so the clean-end branch was
unreachable and every dead parent read as unreadable. That is fail-safe but it
would have made the orphaned handoff helper refuse forever, since a dead parent
is its normal state.

The lock was not exclusive. It created a uniquely named staging file with wx and
renamed it over the lock path, and wx on a unique name always succeeds - so two
racers both renamed and both believed they held it, which is exactly the case the
lock exists to prevent. Acquisition now uses O_EXCL on the contended path itself;
the rename survives only where the caller already owns the lock and hands it to
its helper.

Also: an unreadable uid on macOS is now a probe failure rather than an empty
process list, because reporting "nothing is running" is how #2557 misled users;
and a Linux relaunch whose spawn never happened now throws instead of reporting
relaunch: "started", since a detached child reports failure asynchronously to
nobody.

Verified by direct exercise: exclusive acquire, own-pid reentrancy, transfer to a
helper, contender refusal after transfer, helper inheritance, non-owner release
being a no-op, owner release, and dead-owner reclamation all behave as specified.

* fix(codex): keep the tree compiling after the reason-union rename

windows_only no longer exists, but handleDesktopAppRestart still switched on it,
which is a strict tsc error (TS2678) rather than a stale string. The case becomes
unsupported_platform, and restart_in_flight and relaunch_failed get their own
messages so the two outcomes the new ladder can actually produce are not silently
swallowed by the default branch.

The off-Windows test asserted a windows_only skip for darwin. darwin now has a
real adapter, so the property worth keeping is not "darwin does nothing" but "a
platform with no adapter refuses without execing anything" - the fail-closed
behaviour the original case was really protecting. It now drives freebsd.

The suite also has to stop contending on the developer's real lock: every scripted
case gets its own temp lock path, or a leftover from an interrupted run would fail
every case with restart_in_flight and a passing run would write into a directory
the tests do not own.

Focused file only: bun test tests/clients/desktop-app-restart.test.ts -> 19 pass,
0 fail, including every original Windows kill-authority guard and both #2557
cases, which is what shows the move preserved Windows behaviour. The product
suite, build and typecheck remain NOT RUN by standing constraint.

* fix(codex): stop a corrupt restart lock from wedging every future restart

readRecord treats a truncated or malformed lock file as absent, but the exclusive
create then failed with EEXIST and acquire reported contention with an owner of 0
- a lock nobody holds and nobody can clear. That is the opposite of what the
comment above it promised, and it is reachable whenever a writer dies between
creating the file and writing to it.

A file that names nobody is now unlinked and retried exactly once, so a real
winner that appears in between still keeps the lock. Verified directly: a lock
containing "{not json" and an empty lock are both reclaimed.

* test(codex): give every desktop-restart case its own lock path

Four cases built their io inline and so used the real ~/.opencodex lock. They
passed only because own-pid reentrancy makes serial runs look fine; a leftover
lock from an interrupted run would have failed them, and a passing run wrote into
a directory the tests do not own. An isolatedLock() helper replaces the inline
temp path so a future case cannot forget it.

19 pass / 0 fail on the focused file.

* test(codex): cover the macOS and Linux halves of the desktop restart

The Windows cases already existed and still pass unchanged, which is what shows
the move to a shared ladder preserved that platform. These cover what the move
added.

The macOS cases are written against the behaviours the measurements produced
rather than against the implementation: a crashpad handler at ppid 1 is never a
target (four of them exist on a live machine, and a plain "parent is not a member"
rule would have signalled every one and let a survivor block the relaunch), an
executable path containing spaces and parentheses still parses (this app's helpers
are literally named "Codex (Service)"), a ps probe that throws reports
process_probe_failed rather than no_targets, a bundle whose identifier is not
com.openai.codex is not discovered even though it is named ChatGPT.app, and a
failed relaunch is relaunch_failed rather than targets_survived.

The boundary test is covered directly with the sibling directories it exists to
reject - ChatGPT.app-evil and chatgpt-evil - since a raw startsWith would admit
both and the same user can create them.

The lock cases cover refusal rather than queueing, own-pid reentrancy and the
transfer that lets a helper inherit ownership, a non-owner release being a no-op,
dead-owner reclamation, and a corrupt file not wedging every future restart.

Focused files only: 15 pass / 0 fail here, 19 pass / 0 fail on the Windows file,
17 pass / 0 fail on the two test-layout guards, which confirm the desktop- seed
resolves this file to clients with no explicit entry needed. Suite, build and
typecheck remain NOT RUN.

* test(codex): make the restart_in_flight case independent of pid roulette

The case seeded the lock with process.pid + 1 and only stated liveness on the
seeding side, leaving the restart's own lock io to the real isAlive. Run alone
that pid happened to exist and the case passed; run alongside the other files it
did not, so the lock read as stale, was reclaimed, and the restart proceeded. The
behaviour under test is contention, not whether a neighbouring pid is allocated.

* docs(devlog): record the wp2 outcome and the direction for wp5

* feat(codex): restart the Codex app you are running inside

The self-ancestry guard is right to refuse a direct restart, but on a developer
machine it fires in the normal case rather than a corner case: the measured shell
is zsh -> bundled codex app-server -> ChatGPT -> launchd, so anything run from a
Codex terminal or agent session sits inside the tree it is asking to restart.
Without a handoff the merged --restart-codex would refuse in exactly the
situation that produced the original "it does nothing" report.

The refusal becomes a handoff. A detached helper outlives the caller, waits for it
to exit, re-enumerates, and restarts from outside the tree. Two properties make
that safe: waiting for the caller means the helper is orphaned and therefore
unreachable by a tree walk (which matters on Windows, where taskkill /T follows
live parent links and orphans are never reparented), and the helper re-runs the
ancestry check itself with allowHandoff: false, so recursion is structurally
impossible rather than merely unlikely.

The lock is transferred, not contended for. Handing it over after a successful
spawn is what avoids the deadlock the obvious reading produces - a helper waiting
on a lock its own parent holds - and own-pid reentrancy means the helper runs the
same ladder as everyone else with no special path.

The command is hidden on purpose: routed before the dispatch table, absent from
the registry, from help and from the generated skill surface. It exists so the
helper is the same audited binary running the same audited ladder rather than a
second implementation in a shell script. It is also unauthenticated on purpose,
because it grants nothing a same-uid process could not already do with kill.

The caller-exit wait is bounded by polls as well as by the clock, so a frozen
clock or a no-op sleep cannot turn a detached process nobody is watching into a
hot spin.

10 focused tests: helper-command resolution for the checkout, the npm shim and an
unresolvable invocation; lock transfer to the helper; a pidless spawn cleaning up
its plan; the caller-exit wait; refusal when the caller outlives the window; plan
expiry; an unreadable plan; and allowHandoff never being true in the helper.

* fix(codex): close two handoff defects an audit found

A failed lock transfer was reported as a started handoff. The caller then skipped
its release, so the lock kept naming a process that was about to exit; it read as
stale for the whole twenty-second helper wait, and a concurrent restart could
reclaim it and run a second ladder - the dual-kill the lock exists to prevent.
Transfer failure is now its own outcome, and the helper independently refuses to
act unless the lock names it, so a spawned helper whose transfer did not take
becomes a no-op rather than an unsupervised restart. That check is what
helperOwnsLock was gesturing at; it is now real and used rather than exported
dead, and readDesktopRestartLockOwner gives it something to read.

The helper also unlinked whatever --plan pointed at, before parsing it. A same-uid
caller could pass a config path and have it deleted on the way to being told the
plan was unreadable, which made a hidden helper command into an unlink oracle. The
path must now sit directly in the opencodex home and be named like a plan this CLI
writes, and the unlink happens only after the shape parses.

14 focused tests, adding: a transfer that did not take, a --plan outside the home,
a plan whose name this CLI would never write, an unreadable plan surviving rather
than being deleted, and the helper refusing when the lock names somebody else.

* docs(devlog): record wp5 built and the open cycle's work-phase binding

* feat(cli): give --restart-codex one meaning across every command

--restart-codex now restarts the app-servers AND fully quits and relaunches the
Codex desktop app, on all three platforms. --restart-desktop-app becomes a
deprecated alias that says so, and --restart-app-server-only carries the old
narrow behaviour, so nothing is lost - the scope that used to be the unnamed
default now has a name, which is the better arrangement anyway.

The three flags read the same way in sync, sync-cache and catalog pull. catalog
pull previously documented desktop restart as out of scope; that was a statement
about a capability that did not exist cross-platform, not the consent decision
that split the sync flags, and a flag that means different things depending on
which subcommand follows it is the confusion this change exists to remove. Its
knownFlags set is closed, so the new flags had to be listed there or catalog pull
would have rejected the very flags sync accepts.

Contradictory scopes resolve to the NARROW one. Losing live conversations is
unrecoverable and a stale model picker is not, so a user who typed
--restart-app-server-only keeps their conversations even if another flag says
otherwise.

App-servers inside the desktop tree are excluded from the signal pass when a
desktop restart will also run. The app-server is a child of the app on every
platform, so signalling it and then quitting the app interrupts the operator's
in-flight turn twice in one command. A discovery or probe failure yields no
exclusion, which is the safe direction.

The wire restartCodex field on the connected-sync path keeps app-server-only
meaning and stays unhonored. A remote hub must not end a local user's
conversations because a field name grew underneath it.

readRestartScope and the post-write handler live in their own module rather than
in dispatch, because catalog.ts needs them too and importing them from dispatch
would make the two files circular.

catalog pull's envelope gains desktopAppRestarted, true only for a completed
relaunch - a handoff is not a success, since the restart has not happened yet when
the envelope is written.

Verified by invocation: the usage line lists the new flags, --restart-app-server-only
is accepted instead of rejected as a usage error, and --restart-desktop-app prints
its deprecation notice. 48 focused desktop-restart tests still pass.

* feat(codex): restart the desktop app from the management path too, and refresh the flag docs

ocx system codex-restart restarted the app-servers and stopped there, which left
the model picker exactly where the operator was complaining about it - the picker
lives in the desktop app, not in the app-server. It now restarts both through the
same module the CLI uses.

The desktop restart runs BEFORE the early returns on purpose: "no app-server is
running" is not a reason to leave a stale roster on screen, and an operator who
pressed restart still wants the app back on the current catalog.

allowHandoff is false on this path. The handoff waits for the CALLING process to
exit, and this runs inside a long-lived proxy that does not, so every handoff
started here would sit out its twenty-second window and fail after the operator
had already been told it was handed off. An honest refusal beats a promise the
architecture cannot keep.

CodexRestartResponse gains an OPTIONAL desktopApp summary. Optional because the
guard is a version-skew check the GUI runs and a dashboard talking to an older
proxy has to keep working; the guard validates the shape and its cross-field
invariant - a started relaunch cannot have left a survivor - only when present.
It stays scalar-only: pid lists and a closed-vocabulary reason, never a command
line or an OS error message.

Help, capabilities, the doctor action and the stale-app-server hint all stopped
describing a Windows-only opt-in that no longer exists. skills/ocx is regenerated
from capabilities rather than hand-edited.

48 focused desktop-restart tests still pass; ocx sync --help renders the new
contract.

* docs: describe the merged restart contract in English and every locale

Seven locales exist and all of them documented --restart-codex as app-server-only,
which the code no longer is. Leaving them would have left translated pages
contradicting the English source, which this repository treats as a defect rather
than a backlog item.

zh-cn, zh-tw, tr and ru also carried the catalog-pull desktop-restart exclusion
sentence alongside English; that sentence is removed everywhere it appeared,
because the flag now means one thing across sync, sync-cache and catalog pull.

Each locale is written in its own language and register rather than machine
translated, and only the sentences the contract change touches were altered.

29 files: 5 English pages plus the locale pages that actually mention these flags.
Locale files without a codex-restart row, and factory-droid pages that do not
exist in that locale, were left alone rather than invented.

* fix(codex): actually implement the desktop-tree app-server exclusion

handleRestartScopeAfterWrite passed excludePids to
afterCatalogWriteHandleAppServers, but the option existed in neither the interface
nor the implementation. Under strict tsc that is an excess-property error on the
object literal, and had it compiled the exclusion would have silently done
nothing - the double interruption it exists to prevent would have shipped looking
like it was handled.

The option is now declared and applied: pids already covered by a desktop restart
in the same command are filtered out of the signal pass, because the app-server is
a child of the desktop app on every platform and quitting the app terminates it
anyway. Standalone app-servers are not members of that tree and are still
signalled.

* fix(cli): emit the desktop half of a catalog pull, and invert the contract test

catalog pull computed desktopAppRestarted and then dropped it, so a script could
not see the desktop half of a restart it had asked for. Worse in combination with
the desktop-tree exclusion: app-servers get skipped because a desktop restart is
coming, the desktop restart then fails, and the envelope reported ok: true with
codexRestarted: false and no desktop field at all. A desktop restart that was
requested and did not relaunch is now an incomplete restart, exactly like a
surviving app-server.

The source-oracle test that forbade --restart-codex from implying a desktop
restart is inverted rather than deleted. It encoded the consent decision this work
supersedes, and deleting it would leave the NEW guarantee unenforced. It now pins
that every command routes through one scope reader, and a second test pins that
--restart-app-server-only is the only thing that leaves the desktop app running
and that the deprecated alias still announces itself.

* docs(cli): name the Windows exclusion limitation where the code makes the decision

* fix(cli): stop the desktop failure being clobbered, and finish inverting the oracles

restartIncomplete was ASSIGNED from the app-server result, so a failed desktop
restart was discarded whenever any app-server had been signalled - which is the
common case on Windows, where the exclusion is a documented no-op. It is now only
ever set, never cleared.

"Desktop app is not running" no longer counts as an incomplete restart. The
app-server half already treats nothing-to-do as success, and the two halves
disagreeing would have made catalog pull exit 1 on a machine with no desktop app.

Two neighbouring source-oracle tests still pinned the pre-merge dispatch shape -
includes("--restart-codex"), afterCatalogWriteHandleAppServers and
restart: restartCodex inside the sync and sync-cache handlers. None of those
strings exist there any more, so both would have failed CI. They now pin the
scope reader and the shared post-write helper, with the real-write gate still
required to precede it.

* docs(devlog): close wp3 with its two reviewed residuals

* fix(codex): never claim a stop the process list contradicts

Measured on a real Windows host: the ladder returned
{"stopped":[27788],"surviving":[],"relaunch":"started"} while the app kept its
original pid AND start time throughout. It reported a restart it had not
performed, then relaunched into an app that had never quit - a false success,
which is worse than the stale picker this whole change exists to fix.

Two causes, both in the same helper. stillSameProcess returned a boolean over
three distinct situations: the process is the one we verified, it is gone, or the
probe could not run at all. The caller read false as "already exited" and recorded
a stop without signalling anything, so a failed re-probe became a successful
restart. And a stop was claimed on pid-based liveness alone, which is a weaker
instrument than the platform's own process list; on a packaged Windows app the two
disagree.

checkIdentity now returns same / gone / unknown, and unknown is a survivor rather
than a success - it blocks the relaunch, which is the right outcome when the tree
state cannot be established. A stop is claimed only when liveness AND the
enumeration agree the process is no longer listed.

The test doubles modelled exit purely through isAlive and kept listing terminated
processes, which is why no amount of code review surfaced this. They now drop a
process from the enumeration once liveness reports it dead, like a real process
list. Two regression tests pin the measured behaviour directly and were driven red
against the unfixed ladder before being fixed.

48 -> 50 focused tests, 0 fail.

* fix(codex): confirm a stop by polling the process list, not by asking once

Measured on Windows: taskkill /T /F succeeds, the process is genuinely dead a
moment later, and the very next Win32_Process query still lists it. A single
post-kill enumeration turned that lag into a reported survivor, which blocked the
relaunch and left the machine with the app killed and never restarted - the mirror
image of the false success fixed in the previous commit, and no better.

Both waits now poll until the platform's own process list stops listing the
target, with a final look after the deadline so a process that exits during the
last sleep is not reported as surviving on poll timing alone. A probe that cannot
run keeps the loop going rather than deciding either way, and an expired deadline
without a clean "gone" is still a survivor, so the fail-closed direction is
unchanged.

This is what the live host taught that no test could: the kill and relaunch
primitives were always correct on Windows; the confirmation step was reading a
stale list and drawing the wrong conclusion from it in both directions.

* fix: make the macOS restart cases hermetic and redact a foreign home path

Hosted CI failed four jobs at the exact head, from two causes.

The macOS cases pointed at /Applications/ChatGPT.app. Discovery resolves the
bundle through realpathSync, which touches the real filesystem and cannot be
intercepted by the exec seam, so these passed on a machine with Codex installed
and failed on a runner without it. The local pass was an accident of the
developer's own machine, which is the kind of evidence this branch has been
treating as worthless everywhere else. They now build a real bundle under a temp
directory and realpath it there, so the fixture and the adapter agree - on macOS
the temp tree lives under /var, a symlink to /private/var, and leaving the fixture
unresolved puts every enumerated process outside the resolved root.

The privacy scan caught a second user's home path in two devlog files. That gate
exists to stop exactly this, and it worked.

Both were invisible locally: the first because this machine has the app, the
second because the scan was never run here. That is the whole argument for the
hosted gate.

* test: make discovery deterministic in the failed-probe case

The failed-process-probe case let discovery fall through to the conventional
/Applications path, which exists on a developer Mac and not on a CI runner. So a
case written to exercise a failed PROCESS PROBE reported a failed PACKAGE
DISCOVERY instead, and which one you saw depended on the machine. Spotlight now
resolves to the fixture bundle, so discovery succeeds deterministically and the
probe failure is the only thing under test.
…4518)

* feat(devin): pass user and tool-result images to the wire

The wire layer was already multimodal: ChatMessagePrompt field 10 encodes
ImageData {base64_data, mime_type, caption}, verified against extension.js.
The adapter mapping discarded every image.

textFromParts extracted only type:"text" parts and returned a string, so an
image contributed an empty fragment. mapOneMessage then dropped any message
whose extracted text was empty, which means a pasted screenshot with no
caption killed the turn at 0s — the message vanished before the model saw
anything, and the only workaround was running tesseract before sending.
toolResultText did the same to tool-result images.

Convert content at the boundary instead. A data: URL has everything
field 10 needs, so it parses into {mimeType, base64Data}. A remote https
URL cannot be inlined without a fetch and stays as an explicit text
reference rather than pretending the model can see a picture it cannot.
Video has no Devin field and is skipped. An error tool result keeps its
ERROR prefix alongside the images.

The dead toolResultText is removed.

Local product tests, typecheck, build and install: NOT RUN.
Hosted exact-head CI on this PR is the merge proof.

* docs(devlog): close devin image passthrough unit with merge record
…-web-search-bridge-backends

Lane I5 of the contributor carry train, and a deliberately scoped slice of #4429 rather than a claim to close it.

Reported by @mdwsk88: Codex App sends a hosted web_search declaration through a key-auth openai-responses passthrough, the gateway answers with a client function_call named web_search instead of running hosted search, and the undeclared-tool guard cuts the stream.

What this lands: the sidecar executors for openai, anthropic, xai, gemini and exa now arm the passthrough bridge when an operator explicitly sets webSearchBridge.backend, where before only ollama did even though the type accepted all six. An already-hosted web_search_call still passes through untouched and the undeclared-tool guard is unchanged.

What it deliberately does not land: the mixed-tool continuation. The reporter's own probe ends with two pending client calls, exec and web_search, which the bridge still refuses with web_search_bridge_mixed_tools. Making that work needs a continuation design that preserves the client's exec call and call_id and their ordering, without executing it proxy-side and without losing hosted-search items the relay already completed. #4429 stays open for it. The DeepSeek XML case in that thread is a different contract and is deliberately not treated as an executable search — turning model prose into tool execution is a security boundary, not a convenience.

Maintainer security review: SAFE TO MERGE, no blocking findings. The credential-isolation claim was verified per backend rather than accepted — only ollama spends the serving provider's apiKey and only on the planner-admitted endpoint; openai uses the ChatGPT sidecar pinned to CODEX_FORWARD_BASE_URL, anthropic its stored OAuth, xai the api.x.ai origin, gemini the registry CCA URL ignoring provider.baseUrl, and exa the hardcoded api.exa.ai with its own key. Incoming request Authorization is stripped before sidecar headers are rebuilt, a missing credential leaves the bridge disarmed instead of falling through to another paid backend, and executeBridgeQueries never switches backends.

The review also surfaced a pre-existing gap this slice does not widen: webSearchBridge.endpoint skips the destination policy that provider baseUrl values go through, so an ollama endpoint of a metadata address would receive the serving API key. That is filed separately as #4519 rather than attributed to this change.

Cross-platform CI run 34759689664 concluded success on 4e18382, the exact head merged here.
PR #4510 merged as d7c7b49. Records the three-host proof, the two Windows
defects the live hosts found that ten audit rounds of code review did not, the two
things hosted CI caught that local runs could not, and the three limitations
carried forward.
* fix(codex): scope the history preflight to the relabel unit

A paginated rollout makes `preflightCodexHistoryInjection` refuse
unconditionally, and that refusal vetoed the whole config write. So
`model_catalog_json` never reached config.toml and both the Codex app and the
CLI fell back to their built-in model list, while `ocx sync` still reported
success because `sync.ts` downgraded that one reason to `catalog-only`.

The refusal now stands down only the conversation-history relabel unit, in
every direction. Config, profile, and catalog always write, the relabel job is
skipped without spawning its Worker, and the reason travels in the message and
in `historyPreflightFailureReason` beside `success: true`. A store that
migrates mid-transaction retires the relabel unit instead of rolling the config
back.

Restore and removal get the same treatment. They open no state database and no
rollout, so the preflight never authorized them, and three routed thread rows
out of 14164 were enough to deadlock apply, removal, and restore at once.

Paginated rollout bytes and thread rows are still never modified.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(codex): only roll a restore back when the store migrates mid-write

The entry preflight and a mid-write recheck report the same refusal string but
mean different things, and collapsing them is what left this home unable to
uninstall.

A store that migrates while the restore is writing is new information: history
was restorable when the operation began, so abandoning it and compensating the
pre-images keeps config and history consistent. Stripping a provider definition
while its threads still point at it would orphan them.

A store already paginated at the entry preflight is not new information. There
the relabel was never available, and refusing only means OpenCodex can never be
removed. Those rows are equally unresolvable either way, so the config half
proceeds and the caller reports the stood-down history unit.

Co-authored-by: Cursor <cursoragent@cursor.com>

* test(codex): pin the transaction-committed proof to the profile, not the journal

A baseline that is already routed writes no journal, so journal presence is not
evidence the artifact transaction committed. The profile is replaced inside that
transaction in every form, so no longer holding the fixture sentinel is.

Also updates the manifest-owned restore case: those rows are already native, so
removing the config orphans nothing and the manifest survives for a later native
writer. Refusing was what made a paginated home impossible to uninstall.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(codex): narrow the stand-down and keep the table its rows need

Review found two real defects in the first cut.

Only `history_paginated_requires_native_writer` stands the relabel unit down,
because Codex allocates paginated rollout ordinals in its own writer and no
retry changes that. An unreadable state database, a rollout whose identity
changed, or a preflight that could not run may all succeed next time, so they
keep the hard refusal and the compensating rollback. Recording them as a
stand-down would mark the transition converged and suppress the relabel forever.

Rows tagged `opencodex` resolve only through `[model_providers.opencodex]`. The
loopback form retires that table precisely because the relabel migrates those
rows back to `openai` in the same pass, so retiring it with the relabel stood
down would orphan every such conversation. A table the home already published
now survives the write.

Restore and removal keep their refusal. There the argument reverses: stripping
the provider definition while its threads still point at it orphans them, and
those paths have no seam for keeping a compatibility table. An already-paginated
home therefore still cannot be uninstalled through the product; that is recorded
as open work rather than shipped half-done.

This pull request adds cross-platform Codex desktop restarts, narrows paginated-history refusal handling, preserves Devin images, expands passthrough web search, repairs routed ciphertext, updates DeepSeek and catalog behavior, and adds extensive tests and documentation.

Changes

Desktop restart

Layer / File(s) Summary
Restart orchestration and adapters
src/codex/desktop-app-restart.ts, src/codex/desktop-app/*
The restart flow now supports macOS, Linux, and Windows through platform adapters. It adds process identity checks, trusted discovery, locking, relaunch context capture, and fail-closed outcomes.
Detached handoff and CLI scope
src/codex/desktop-app/handoff.ts, src/cli/restart-scope.ts, src/cli/dispatch.ts, src/cli/catalog.ts
--restart-codex now includes desktop restart. --restart-app-server-only preserves the narrow behavior. The deprecated --restart-desktop-app alias remains supported. In-app restarts can use a detached helper.
Contracts and validation
src/lib/codex-restart-contract.ts, src/codex/app-server-restart-service.ts, tests/clients/*, tests/codex-integration/*
Management responses can include desktop restart results. Tests cover restart outcomes, locks, handoff, CLI precedence, and catalog envelopes.

History and routing

Layer / File(s) Summary
History preflight scope
src/codex/inject.ts, src/codex/sync.ts, tests/codex-integration/*
history_paginated_requires_native_writer now skips only history relabeling during apply. Configuration, profile, and catalog writes continue. Restore and removal still refuse.
Provider and content routing
src/adapters/devin.ts, src/providers/registry.ts, src/codex/catalog/*, src/web-search/*
Devin preserves images. deepseek-flash uses native image input. Custom native reasoning metadata applies on gateways. Passthrough search supports multiple credentialed backends.
Responses ciphertext repair
src/server/responses/encrypted-payload.ts, src/server/responses/core.ts, tests/server/*
Recognized ciphertext in routed agent messages is replaced before dispatch. Readable text is preserved, and the canonical Codex backend remains exempt.

Supporting records

Layer / File(s) Summary
Plans, records, and documentation
devlog/*, docs-site/*, structure/*, skills/ocx/*, CREDITS.md
Planning, execution, outcome, localized documentation, generated references, and credit follow-ups were added or updated.
Release and test layout
package.json, scripts/test-layout/*, tests/fixtures/*
The package version changes to 2.54.0, and the Devin test is registered in the test layout.

Priority: ⬆️ High

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to a84e6

Remote management sessions may restart the host desktop app, routed ciphertext may reach noncanonical providers, and restart or history-transition failures can be hidden or leave broken state. These issues should be fixed before merge.

이 PR은 새 기능을 만드는 작업이 아닙니다. 이미 dev에 올라와 검증 중인 2.54.0 통합 줄을 미리보기 채널 preview로 올리는 출구입니다. 지금 origin/preview tip은 90ff8aa1d(2.53.0-preview.20260913, #4504 머지)이고, 이 PR head는 dev tip a84e6e827(package.json 2.54.0)입니다. 미리보기보다 29커밋 앞선 줄을 통째로 가져옵니다. 맨 앞에 서 있는 이유는 #4531입니다. Codex 0.154 계열에서 페이지네이션 history preflight가 config 쓰기 전체를 막아서, model_catalog_jsonconfig.toml에 안 들어가고 앱·CLI가 내장 모델 6개만 보이던 사고입니다. ocx sync는 그걸 성공처럼 보여 줬습니다. #4531은 그 거절을 대화 히스토리 relabel 유닛만 세우도록 바꿨고, tip CI 런 34772128322가 exact head에서 25개 초록이었습니다.

그 29커밋 안에는 미리보기에 아직 없는 큰 덩어리가 더 있습니다. #4510/#4520 크로스플랫폼 desktop-app restart(--restart-codex가 앱까지 다시 띄움), #4515 webSearchBridge 비-Ollama 백엔드 무장, #4498 encrypted agent_message 사전 수리, #4513/#4518 Devin 이미지 패스스루, 기여자 carry train 기록, 그리고 #4506으로 연 2.54.0 버전 오픈입니다. 지금 로컬 dev 스냅샷도 같은 HEAD를 보고 있고, 방향은 Codex inject/sync 신뢰·웹검색 브리지·데스크톱 재시작·릴리즈 열차입니다. types.ts/config.ts 분리 캠페인과는 직접 충돌하지 않습니다.

점수를 70 위로 안 올린 이유가 분명합니다. GitHub가 이 PR을 CONFLICTING / DIRTY로 표시합니다. 충돌 파일은 package.json 하나뿐입니다. preview 쪽은 2.53.0-preview.20260913, head 쪽은 2.54.0이라 버전 한 줄이 서로 다릅니다. 이전 미리보기 승격(#4504)은 검증 tip과 파일 내용이 같고 채널 버전만 …-preview.YYYYMMDD로 바꾼 컷이었습니다. 이번처럼 dev를 base preview에 그대로 붙이면, 충돌을 풀 때 버전을 그냥 2.54.0으로 두면 미리보기 채널 이름 규칙과 어긋납니다. 짝 PR #4537(main 승격)은 mergeable이고, 안정 채널에 2.54.0을 올리는 쪽이 맞습니다. 미리보기는 보통 2.54.0-preview.20260914 같은 날짜 접미가 필요합니다. Cross-platform CI·enforce-target도 아직 도는 중이라, tip 초록이 최종 게이트입니다.

경로/심볼 - package.json - preview(2.53.0-preview.20260913)와 dev(2.54.0)가 충돌한다. 머지 전에 채널 버전으로 풀어야 한다. 권장 형태는 2.54.0-preview.20260914(오늘 KST 날짜)처럼 이전 #4504 패턴을 따르는 것이다.
경로/심볼 - base preview / head dev - 제품 트리를 통째로 끌어올리는 메인테이너 승격이다. 기여 PR용 enforce-target(dev로 리타깃 안내)이 뜨면 #4504/#4406과 같은 오탐으로 보고, base를 dev로 바꾸면 안 된다.
경로/심볼 - #4531 / src/codex/inject.ts / src/codex/sync.ts - history preflight stand-down이 이번 줄의 헤드라인이다. exact-head CI 초록이 이미 있다.
경로/심볼 - #4510 desktop restart / #4515 webSearchBridge / #4498 ciphertext repair / #4513 Devin images - 미리보기에 아직 없는 2.54 줄의 큰 탑재물이다. 각각 자기 PR에서 리뷰·CI를 거친 뒤 dev에 들어왔다.
경로/심볼 - #4519 (OPEN) - webSearchBridge.endpoint가 destination policy를 건너뛴다. #4515가 새로 벌린 구멍이 아니라 같이 적힌 선재 갭이다. 승격 블로커로 볼지는 메인테이너 판단이다.
경로/심볼 - #4429 (OPEN) - mixed-tool continuation은 #4515가 일부러 안 닫았다. 미리보기 노트에 “부분 착륙”으로 쓸지 정하면 좋다.
경로/심볼 - 페이지네이션 home uninstall - #4531 이후에도 restore/remove 쪽 한계가 남아 있다. 릴리즈 노트에 쓸지, 후속 이슈만 둘지 결정이 필요하다.
경로/심볼 - 짝 #4537 - 같은 tip을 main2.54.0으로 올리는 PR이다. preview와 main을 같은 tip으로 맞출지, preview만 먼저 올릴지 순서를 정하면 된다.

충돌부터 풀고, 버전은 2.54.0-preview.20260914(또는 머지 당일 KST 날짜)로 맞춘 뒤 tip Cross-platform CI 초록을 확인하고 merge하라. base를 dev로 리타깃하지 마라. #4519/#4429는 이번 승격을 막지 말고 릴리즈 노트·후속으로 남겨라. 짝 #4537은 main용 2.54.0 그대로 두고, preview와 tip을 맞출지 순서만 정하면 된다. types/config 분리와 무관하니 close-don't-rebase 대상이 아니다.

P1 Badge Propagate desktop restart failures

When the desktop restart returns self_ancestry, targets_survived, or relaunch_failed, its result is merely attached to the response while success and code remain based solely on app-server state. In the common no-app-server case this returns success: true and nothing_running, so the existing dashboard announces success even if the desktop app was left stopped or never restarted. Incorporate the desktop outcome into the top-level result and expose a failure code the GUI can render.

P1 Badge Stub desktop restart in service tests

The new seam is optional, but the existing tests/codex-integration/codex-app-server-restart-service.test.ts baseIo and several direct IO objects do not provide it. Consequently every call in that focused test file now falls through to defaultRestartDesktopApp; on a developer host with Codex installed, running the suite can terminate and relaunch the developer's real desktop app and interrupt live conversations. Supply a harmless default stub in the test fixture and override it only in explicit desktop-restart cases.

P2 Badge Return failure when the requested desktop restart fails

For ocx sync --restart-codex, the returned RestartScopeOutcome is discarded, so failures such as package_discovery_failed, process_probe_failed, self_ancestry, targets_survived, or relaunch_failed only print an error while the command still exits 0; sync-cache has the same pattern. This makes automation believe the newly promised full restart completed even when it did not, unlike catalog pull, which explicitly emits restart_incomplete. Use the outcome to set the command exit/envelope status, while treating no_targets and an accepted handoff appropriately.

P1 Badge Remove closed units from _plan

This adds a stale open-plan copy even though the same commit also adds devlog/_fin/260913_devin_image_passthrough/000_plan.md with the terminal outcome; the two copies already contradict each other because only the _fin copy records the merge. The cross-platform restart and contributor-carry directories similarly contain explicit terminal outcome records while remaining under _plan. Remove the duplicate and move every terminal unit to _fin so the repository's open-work inventory is accurate.

Inline comments:
In `@devlog/_plan/260913_contributor_carry_train/000_plan.md`:
- Around line 134-137: Revise the paragraph describing issue lanes I1–I4 so it
applies only to the initial inventory, not all later dispatch outcomes. Document
that dispatch may identify and carry a contributor pull request, including the
I3 case for `#4467` with its author trailer, while preserving the existing
description-credit rule for lanes without a source branch.

In `@devlog/_plan/260913_contributor_carry_train/020_wave1_merge.md`:
- Around line 37-45: The merge verification guidance should distinguish
attribution checks by landing strategy: for cumulative merge commits, inspect
each carried source commit for its Co-authored-by trailers rather than relying
on the merge commit message; for squash merges, retain the merge-commit message
check. Update the exit criterion to require the appropriate check for each path,
using the existing merge and squash workflow terminology.

In `@devlog/_plan/260913_contributor_carry_train/030_wave2.md`:
- Around line 38-39: Resolve the undefined I5 lane reference in the lane
description by replacing it with the established lane identifier supported by
the plan, or fully defining I5 with its owner, source, parent, and exit criteria
before using it.

In `@devlog/_plan/260913_contributor_carry_train/050_disposition.md`:
- Line 20: Update the disposition entries in 050_disposition.md so issue `#4170`
is removed from lane L’s carried-source list with `#4382` and `#4413`, and recorded
only under the already-satisfied-on-dev disposition.

In `@devlog/_plan/260913_contributor_carry_train/060_outcome.md`:
- Around line 3-4: Update the opening summary in 060_outcome.md to match the 11
unique lanes: state that eleven lanes were dispatched, ten landed, and one
needed nothing; remove the incorrect separate-lane claim.

In `@docs-site/src/content/docs/reference/cli/lifecycle.md`:
- Line 348: Update the restart_incomplete CLI lifecycle documentation row to
cover incomplete Codex app-server and desktop relaunches, including cases where
desktopAppRestarted is false while catalogWritten and cacheSynced remain true;
retain the existing exit-code value.

In `@docs-site/src/content/docs/reference/proxy-formats.md`:
- Around line 702-703: Update the documentation sentence describing
allowEncryptedV2AgentTasks so the exemption is explicitly limited to direct
routes: direct trusted routes remain unaffected, while trusted routes used as
combo children undergo omission-marker repair per target. Keep the statements
about translated wires and other item types unchanged.

In `@src/adapters/devin.ts`:
- Line 231: Update the data-URL matching in the image handling flow around
part.imageUrl so valid media-type parameters before ;base64, such as
charset=utf-8, are accepted and decoded as image data rather than treated as
text references. Preserve existing MIME and payload extraction, and add coverage
for this parameterized URL in devin-image-passthrough.test.ts.

In `@src/cli/catalog.ts`:
- Around line 87-89: Update the final incomplete-restart message in the catalog
restart flow to avoid always claiming that an app-server is running the previous
catalog. Use the desktop restart reason from outcome.desktopApp.reason, or a
neutral message stating that the requested Codex restart did not complete, while
preserving the existing restartIncomplete classification.

In `@src/cli/dispatch.ts`:
- Line 400: Update the shared restart handling around
handleConnectedSyncCatalogWrite and the other affected call sites to inspect the
returned RestartScopeOutcome and propagate incomplete or terminal restart
results as a non-zero command exit status. Preserve the existing defined
treatment for no_targets and handoff_started, and ensure sync, connected sync,
and sync-cache do not report success when relaunch, target handling, or
app-server stopping fails.

In `@src/cli/registry.ts`:
- Line 150: Synchronize restart warnings in the catalog pull metadata with the
details used by sync: document that --restart-codex quits and relaunches Codex
Desktop, ending live conversations, while --restart-app-server-only keeps
Desktop running and takes precedence. Update the system codex-restart summary
and --yes summary in the relevant capabilities definitions to include the same
Desktop and live-conversation impact, while preserving the existing refusal
condition for proxies running inside Codex.

In `@src/codex/app-server-restart-service.ts`:
- Line 140: The desktop restart invoked by defaultRestartDesktopApp from the
restart flow must not block the proxy event loop: move the complete synchronous
restartCodexDesktopApp ladder, including process execution and waitUntilGone
polling, to a worker or detached helper, or make the entire ladder asynchronous.
Do not only replace the sleep seam; ensure the await in the desktop restart call
can yield while graceful and forced restart windows are running.
- Around line 132-139: Protect CODEX_RESTART_PATH in handleSystemRoutes with a
dedicated local capability check before invoking performRestart, and explicitly
reject requests whose ctx.principal is gui-session. Add or reuse a capability
specific to Codex desktop restart, separate from system-restart-capability,
while preserving existing behavior for authorized local callers.

In `@src/codex/desktop-app-restart.ts`:
- Around line 326-333: Verify the replacement shell is live before reporting
restart success: in src/codex/desktop-app-restart.ts lines 326-333, poll
listProcesses() for the new root-shell identity until a bounded timeout, then
return relaunch_failed if it never appears. In src/codex/desktop-app/linux.ts
lines 356-365, treat the setsid PID only as dispatch evidence and rely on the
shared shell-identity check to determine success.

In `@src/codex/desktop-app/darwin.ts`:
- Around line 129-131: Update the running-bundle discovery loop around
readPsSnapshots so it only considers snapshots whose uid matches the current
user, while retaining the existing shell-suffix check and executable path
extraction for matching snapshots.

In `@src/codex/inject.ts`:
- Line 1351: The transaction flow around observeHistoryRefusalOrThrow must
rebuild content, the candidate, and the witness with the retained
[model_providers.opencodex] provider table when
history_paginated_requires_native_writer is discovered, including at both
refusal points. Rebuild before pre-image capture and writes for the first
discovery; for the later discovery, restore current pre-images and retry using
the rebuilt candidate and witness, preserving the non-throwing stand-down
behavior.

In `@src/server/responses/core.ts`:
- Around line 6245-6259: Update the shared canPassThroughEncryptedV2AgentTask
exemption to require isCanonicalOpenAiForwardProvider(provider) in addition to
the existing authentication and adapter checks, preventing noncanonical custom
key routes from bypassing ciphertext stripping. Preserve per-target wire
resolution for combo children.

All four issue lanes — I1, I2, I3 and I4 — have no branch to carry at all. Those
are ordinary implementations by the lane thread, and they carry no
`Co-authored-by` trailer because there is no source branch; the reporter is
credited in the description instead.

Qualify the no-trailer rule for issue lanes.

The final outcome records #4467 as a contributor pull request discovered during dispatch and carried by lane I3 with an author trailer. Therefore, the unconditional statement that I1–I4 have no branch to carry and need no Co-authored-by trailer is false for I3. Scope this paragraph to the initial inventory and document the dispatch-time carry exception.

5. Merge the tip. A cumulative lane merges as one merge commit on the tip, which
lands every link beneath it. A lane whose links must appear separately in
history squash-merges bottom-up instead.
6. Verify the landing rather than trusting the merge report:
git merge-base --is-ancestor <merge-sha> origin/dev.
7. Verify attribution in the landed commit: git log -1 --format=%B <merge-sha>
must show the Co-authored-by trailers for every carried author. A trailer that
lived only in the pull request body is gone after a custom squash message, and
that is exactly the failure CREDITS.md documents.

Resolve the undefined I5 lane reference.

I5 appears only in 030_wave2.md:38-39. The plan defines lanes H, I3, and I4; it states that H starts from I4's pushed head and provides no owner, source, parent, or exit criteria for I5. The intended replacement cannot be determined from the record. Replace I5 with the established lane identifier, or define I5 completely.

Move the desktop restart off the proxy request path.

defaultRestartDesktopApp at src/codex/app-server-restart-service.ts:36-45 invokes synchronous restartCodexDesktopApp after the dynamic import. That function selects defaultSleep, which calls Atomics.wait at src/codex/desktop-app-restart.ts:117-119. When waitUntilGone polls a live shell at lines 182-186, the await at line 140 cannot yield. The polling loop can block the proxy event loop for the graceful and forced windows, delaying other proxy requests and streams.

Run the synchronous ladder in a worker or detached helper, or make the complete ladder—including process execution and polling—async. An async sleep seam alone is insufficient.

Scope running-bundle discovery to the current user.

This loop can select another account's Codex shell because it does not check snapshot.uid. If that account uses a different bundle path, listProcesses() later filters its processes out and returns no roots. The restart then reports no_targets even when the current user's app is running.

Rebuild the candidate when paginated history appears during the transaction.

The retention branch at src/codex/inject.ts:1252-1257 runs before the candidate and witness are built. If observeHistoryRefusalOrThrow() first returns history_paginated_requires_native_writer at line 1351, the existing content and witness still omit the retained [model_providers.opencodex] table. If it first returns at line 1387, the config and profile have already been written. The stand-down is non-throwing, so neither path enters compensation. The later flow skips the history worker at lines 1545-1547 and reports success.

In the root-override form, existing rows tagged opencodex then have no provider table. This violates structure/config.md:161-174, which requires an already-published provider table to survive a stood-down relabel.

When line 1351 discovers the refusal, rebuild content, the candidate, and the witness with the existing provider table before capturing pre-images and writing. When line 1387 discovers it, restore the current pre-images and retry with the rebuilt candidate and witness.

…end (#4548)

sidecarSettingsForBridge read the model out of the global config.webSearchSidecar
block without checking which backend that block was configured for, and
src/server/responses/core.ts hands the block over whole. A global
{backend: "openai", model: "gpt-5.6-luna"} therefore reached runAnthropicWebSearch
whenever a provider set webSearchBridge.backend to "anthropic", and Anthropic
rejects the model, so the bridge search failed. Same shape for xai and gemini.

The global model now applies only when resolveSidecarBackend(sidecar.backend)
equals the bridge backend; otherwise the bridge runs that backend's own default.
An unset global backend still resolves to "openai", so an unset-backend model
reaches an openai bridge and no other. Only the model is gated: reasoning is a
generic effort level, and xSearch is xai-only with no per-backend default and no
webSearchBridge equivalent, so gating it would make an openai sidecar plus an xai
bridge plus x_search inexpressible.

No credential crosses a backend, before or after this change.
resolvePassthroughWebSearchBridgeAuth switches on the bridge backend and consults
only that backend's credential locator. This is a model and settings defect.

resolveSidecarBackend and WebSearchBackendId move from src/web-search/index.ts to
src/web-search/sidecar-providers.ts, which exists precisely so the bridge can
resolve a backend without value-importing the barrel; index.ts re-exports both, so
every existing consumer is unchanged.
…4547)

parseCatalogBuffer had arms for ClientModelConfig fields 1, 4, 18 and 22
and no default, so field 5 (supports_images) was dropped by omission.
Carry it on ModelCatalogEntry as an optional boolean: a present true
asserts text+image support, a present false asserts text-only, and an
omitted field stays unknown. It deliberately does not copy the disabled
pattern, which defaults to false — collapsing unknown into text-only was
the #1796 regression, and antigravity-models.ts already implements the
same tri-state for its discovered catalog.

The header schema comment gains the #5 row and the #18 row it never
listed, and its verification claim now says which fields came from the
bundled extension.js, which from a live catalog dump, and which from the
public WindsurfAPI documentation. The owning structure doc records the
catalog pre-flight contract. Propagation of the flag to the client
catalog is a separate change.
…nts (#4543)

* fix(cursor): refund spare envelope bytes to clipped invocation arguments

The 2 KiB per-call cap on the arguments named inside a replayed tool-result
envelope is charged while the envelope is still being built, so it cost a call
2 KiB whether or not anything else wanted those bytes. In a small replay nearly
the whole 192-root / 512 KiB envelope went unused and the cap still bit: a
4,693-byte successful write_file lost its tail inside a 6,011-byte replay, and
because the result text does not repeat the argument, the model could no longer
see what it had just written.

Add a second pass after the root set is assembled and before it is stored. It
spends only leftover aggregate bytes, newest tool result first, skips a root
whose own output was already elided, and never drops, shrinks or reorders a
retained root. The cap itself is unchanged and still decides admission on its
2 KiB prefix, so a 600 KiB argument stays clipped rather than evicting the
output it describes.

The gate is echoToolResultInRoot, not externalModel: native composer-2.5 echoes
results into roots without being an external wire model, so the narrower gate
would have left the one native model with clipped invocation lines capped for no
reason. The widening uses the callback form of String.prototype.replace, because
serialized arguments routinely contain $&, $' and $1, which the string form
would expand into the surrounding match.

Closes #4516

* fix(cursor): accept readonly rawMessages in the restoration pass

request.rawMessages is readonly OcxMessage[]; the new second pass declared a
mutable OcxMessage[] parameter, which strict typecheck rejects (TS4104). The
pass only reads the array, so widen the parameter instead of copying.

* fix(cursor): keep a collapsed root's run note through a rebuild

An adversarial counter-read of the restoration pass found the real defect one
layer down. pushDeduped builds the collapsed root's wire payload from the marked
text but stored the UNMARKED text in the candidate's `text` field, so every
consumer that rebuilds a root from `text` silently deleted the "produced N times
in a row" note: truncateToolResultBlob already did, and the new invocation
restoration did too. That note is the repetition breaker's per-entry half, so
losing it re-primes the self-reinforcing loop the breaker exists to end.

Store the marked text, which makes `text` a true mirror of the stored payload
for the first time, and fixes the truncation path by the same change.

Also anchor the restoration's search on the preceding newline. toolResultToText
always emits the invocation after the [tool_result], call_id: and name: lines, so
the real line is never first; name: renders the result's tool name, which nothing
sanitizes, so an unanchored search could be satisfied by a crafted tool name and
rewrite that header instead of the invocation.

The regression test fails with the pushDeduped change reverted and passes with it.

* test(cursor): record why the 600 KiB cap tests are not refund tests

The refund leaves those two fixtures alone because restoring a 600 KiB argument
costs more than the whole envelope, so cost > spare is always true there. That is
a size-dependent skip, not a rule that the line stays clipped: an argument over
the cap but well under the envelope is restored by design. Anyone shrinking those
fixtures to speed them up would silently convert them from tests of the cap into
tests of the refund, which is the one reading that would make them vacuous.

Three leftovers from scoping the history preflight, found by re-reading the
owned docs against the shipped behaviour.

`codex-home.md` still said a detected migration always restores all three
preimages before refusing. That is now direction- and reason-dependent: on apply
the paginated refusal retires the relabel unit and the write stands, because it
is permanent and compensating it produced a home with no OpenCodex models at
all. Every other reason there still compensates, and restore and removal
compensate on all of them, because retiring a provider definition its thread
rows still name would orphan them.

The unattended-sync test stubbed the injector returning a paginated refusal,
which it can no longer produce, so the test guarded an unreachable shape while
still passing. It now stubs an operational reason, which is still a hard refusal.

One preflight test claimed to assert that provider definitions are preserved;
it asserts which target sets reach a paginated row. Renamed to match.

Five regressions for the invocation refund landed in #4543.

- A just-over-cap argument (~2,117 bytes against the 2,048 cap) must come back
  byte-exact. The existing fixture is 4,600 bytes, where thousands of spare bytes
  surround the decision and an off-by-one in the cost arithmetic or in the
  newline-anchored search cannot show.
- No result may be evicted to pay for a wider invocation line, and under the
  fixture's uniform per-round costs the restored set must be the newest
  contiguous suffix. That second claim is a direction check: flipping the walk to
  oldest-first makes it a prefix and turns this red. The comment says so, and
  says plainly that contiguity is not guaranteed under mixed sizes, because the
  pass skips an unaffordable line with continue rather than break.
- A checkpoint-covered call must keep its argument tail in the replayed suffix.
  Drop knownCallsOffset from the pass's callBefore bound and only this case
  notices, since that term is identically zero on the full-replay path.
- A multi-byte argument must survive intact, with U+FFFD asserted absent so a
  failure names itself rather than only showing unequal strings.
- The outputElided skip is load bearing, and finding that out took two tries. A
  sweep of single-result fixtures said the guard was dead code — elision appeared
  to always cut the invocation line too — and an adversarial counter-read found
  the configuration that sweep could not reach. Truncation alone cannot pay for a
  restoration: it undershoots its own budget by about 28 bytes. Initiator
  recovery can. With a ~519.7 KiB system prompt the equal-share pass cuts two
  trailing results to ~2.3 KiB, losing "output:" but keeping the clipped
  invocation line, and recovery then drops the older elided sibling to fit the
  user turn; those freed bytes become spare. The test searches that ~24-byte
  window rather than pinning a literal size, because pinning one made it pass on
  a two-character call id and fail on a twelve-character one, and it fails loudly
  if the window disappears.

Each of the last three was verified by mutation. The two 600 KiB cap tests are
byte-identical. The only src change is the comment recording what the guard
actually depends on, and structure/providers/cursor.md records it too — the
earlier draft of both called the guard defensive, which was wrong.
…og (#4556)

Round 1 made the Devin catalog parser preserve ClientModelConfig field #5
as a tri-state on ModelCatalogEntry; the flag stopped at the cache. Carry
it through: fetchDevinUsableModels now votes per base across the rows that
collapse into it and returns inputModalities, and the Devin branch of
provider-fetch spreads that value before catalogHintsFromProviderConfig,
so exact modelCapabilities declarations, the legacy modelInputModalities
record and the vision-sidecar rewrite keep precedence and the live value
survives only when none of them applies.

Collapse policy, pinned with the round-1 #1796 precedent: rows that never
asserted field #5 abstain, so one unsuffixed unknown row cannot poison a
base whose effort variants were measured image-capable; unanimous measured
rows advertise ["text"] or ["text","image"]; measured disagreement
advertises nothing, because a single measured false is not outvoted by its
siblings. The accepted mismatch is documented in code: resolveWireModelUid
prefers the plain UID when the catalog lists it, so a variant-measured
image base can route a no-effort request to an unasserted plain row.

Tests: a new devin-live-models suite seeds the cache through the real
parser via a setCachedCatalogForTests seam and covers the collapse matrix
(disabled and MODEL_* rows proven non-voters by behavior) plus five
fetchProviderModels advertised-catalog cases locking the hint precedence,
including the existing sidecar path for exact text-only declarations.
Layout registries name the new file; structure/catalog.md and
structure/adapters/registry.md record the contract.
)

The adversarial counter-read of 5d95dbf returned two should-fix findings
and one nit, all folded here: the advertised-catalog tests now stub
globalThis.fetch to throw, so a seeded-cache miss fails the test instead
of dialling Cognition; the catalog.md precedence sentence is scoped to
inputModalities (live contextWindow and reasoningEfforts have their own
configured sources and the broader claim was not literally true) and moved
out of the TTL paragraph; and the registry.md collapse wording covers the
whole EFFORT_TOKENS suffix set rather than only effort variants.
Ten PRs landed on dev across two merge rounds run by four worktree lane threads,
each merged only after the check run's head_sha was verified against the PR head,
with post-merge dev runs 34778300807 and 34782580496 as the joint proof for each
round. #4522, #4530 and #4516 are closed with merge references after an independent
audit of every claim against the tree; eleven issues are deliberately left open with
their residuals named.

#4555 is green and deliberately unmerged: MAINTAINERS.md requires explicit security
review for a change that sends the serving provider's API key to an operator-named
endpoint, and the dev self-integration exception does not cover that review. An
adversarial review found a real silent regression there, which the lane fixed.

Records what the unit learned, including that a fresh lane worktree has no
node_modules so hosted CI is the only evidence that can exist, that a push already
queues CI so the explicit dispatch is a fallback, and that a cancelled dev run is a
concurrency artifact of the release train rather than a failure.
Names the two items still waiting on people: #4555 green and pending the security
review MAINTAINERS.md requires for a credential-destination change, and #4528 whose
only CI failure is a stale-base release version line rather than anything in its
diff. Records that the thread heartbeat was repointed to watch exactly those two and
made read-only by construction, after an audit caught an earlier draft instructing
it to close #4519 automatically on merge, which is not the verified-code-evidence
standard every other close in this unit met.

Superseded by #4541. That PR promoted through a dedicated release branch (codex/release-2540-preview-20260914) and already merged into preview as 4d633cb. This PR targeted preview from dev head directly and is leftover.
