fix(update): keep a history-preflight refusal from aborting the update (#4718) - #4746
Conversation
#4718) [skip ci] On Windows, "ocx update" stopped the service, entered the pending shared teardown path, printed "Native restore refused: history_paginated_requires_native_writer", and then aborted with "could not stop the running proxy". The service was down, no listener was left, and the old package was still installed. Installing the same target by hand worked. The refusal itself is correct and stays. The Codex history preflight runs before the config half of the restore, so it returns an envelope whose config, catalog and history artifacts are all "skipped" -- nothing was attempted. restoreSharedClientStateAfterStop classified only two shapes, a later history failure and everything else, so the refusal fell through to "everything else", ocx stop exited 1, and decidePostStopUpdate read 1 as a proxy that would not die. The reported lane is bin/ocx.mjs; the Bun updater shares the same decision module and had the same defect. The obligation really is outstanding here: config and catalog were never restored, so the client still points at the proxy that just stopped. Treating the refusal as the existing history-only case would have discharged the receipt and lost that. So this adds a third outcome rather than widening the second. - CodexNativeRestoreResult.historyPreflightRefusal carries the refusal as a structured reason. The artifact states cannot carry it: an ownership refusal and a desired-state skip produce the same three "skipped" values, and matching the message would put a safety decision on prose. - ocx stop keeps the receipt, says so, and exits 80. Eighty is not 79: seventy-nine means the teardown ran and only history metadata is pending, and a caller reading it discharges the obligation. - Eighty is only emitted when pendingTeardownsAreExactly confirms the obligations left in the home are exactly the ones this run chose to keep. A quarantined receipt or a concurrent stop's claim falls back to exit 1, which is the pre-existing behaviour, so the fallback loses nothing. - decidePostStopUpdate lets 80 past the teardown gate and nothing else. Runtime records, a live proxy and an unreadable probe abort exactly as before, because a history refusal is evidence about history and says nothing about whether the proxy is gone. - Both updater lanes report the deferral as its own outcome instead of reusing the manifest warning, which would imply config and catalog came back. Closes #4718

When another ocx stop creates an obligation after pendingTeardownsAreExactly() runs but before the updater performs its post-stop checks, status 80 causes this condition to ignore every outstanding receipt, including the newly created one. The updater can then replace package files even though that receipt may belong to a different endpoint whose proxy was not covered by its liveness probe, defeating the concurrent-stop protection described in src/cli/index.ts. Carry verifiable receipt identity to the updater or serialize the proof and update decision instead of exempting the boolean globally.

For the reported history_paginated_requires_native_writer path, closing Codex and rerunning ocx stop cannot finish this restore: structure/config.md:168-170 defines that refusal as permanent, and structure/codex-home.md:257 states that paginated homes currently cannot be restored through the product. This warning therefore sends users into a repeatable exit-80 loop while the receipt remains forever; report the known limitation and an actual recovery path instead, and keep the mirrored launcher warning and public docs consistent.

This introduces a new cross-process exit-code contract and changes when outstanding teardown receipts permit package replacement across the owned src/cli/, src/codex/, src/config/, and src/update/ areas, but the commit updates none of their mapped structure/ documents. Add the deferred-refusal and receipt-exemption invariant to the applicable architecture docs so future lifecycle changes do not unknowingly collapse status 79/80 or restore these receipts incorrectly.

…4691) [skip ci] On a zh-CN host (ACP/OEMCP 936) with a CJK account name, "ocx service repair" and the dashboard repair/install buttons failed against a registration OpenCodex had created itself: Service repair failed: Task Scheduler registration is not a recognized legacy OpenCodex definition; it was preserved for manual review. Redirected "schtasks /query /xml" output follows the console output code page of the spawning process tree, not the XML document encoding. In any 936 context -- including the no-console background service on a zh-CN host -- the bytes are GBK. decodeSchtasksOutput probed UTF-16 and then fell back to a plain UTF-8 decode, so the CJK account name inside <SessionStateChangeTrigger><UserId> became U+FFFD. The correctly resolved expected identity [SID, MACHINE\<name>] then never matched the trigger scope, windowsTaskRegistrationHealthy returned false, and repair aborted at its recognition gate. The same mojibake rolled back fresh installs at post-create verification. The fix is entirely in byte decoding, before any XML is parsed. decodeSchtasksOutput now delegates to decodeWindowsTextBytes, the decoder this project already built for exactly this class (UTF-16, then strict UTF-8, then the locale's legacy code page). It already fixed the sibling whoami/PowerShell decode in src/lib/windows-user-principal.ts (#2914, and #722 for CP949); this call site was the last one still ending in a lossy UTF-8 decode. Task ownership is deliberately untouched. windowsTaskTriggerScopeAcceptable still requires an exact identity match, and the tests assert that a different account and the mojibake spelling are both still rejected. Forgiving a replacement character there would let two different non-ASCII accounts collapse to the same value, which is worse than the refusal it replaces. Delegating also fixes a latent UTF-16BE edge: the old local copy allocated buffer.length - 2 bytes for an odd-length payload and left a trailing uninitialized byte. The shared decoder rounds the payload down instead. Closes #4691

Do not return deferred status without a retained receipt.
claimTeardown() catches claimPendingTeardown() failures and leaves teardownNonce undefined. If stopProxy() then uses its hard-kill fallback, it returns false without setting stopFailed, so handleStop() can still call restoreSharedClientStateAfterStop().
When that restore returns a structured historyDeferred refusal, and no inherited receipt was recovered, line 1163 assigns historyDeferredNonces = []. If no obligation files exist, pendingTeardownsAreExactly([]) returns true; lines 1226-1229 then return exit code 80 while no receipt records the refused teardown. The updater may replace package files, and later stops or updates cannot recover or gate on that teardown.
Set stopFailed when historyDeferred has no retained nonce:

Preserve the retained receipt set through the update boundary.
src/cli/index.ts validates pendingTeardownsAreExactly(historyDeferredNonces) before returning exit code 80. The updater then receives only that code and the result of a later pendingTeardownOutstanding() directory scan. claimPendingTeardown() is not serialized, and ocx start can create a new proxy during this interval. A concurrent stop can therefore create an additional receipt after the child’s exact-set check. Because src/update/stop-decision.mjs:38 ignores teardownOutstanding for exit 80, the updater can proceed with a receipt that was not part of the child’s validated set.
Pass the retained nonce set through the process boundary. Acquire a shared teardown/update lock before the updater’s final exact-set validation, make receipt claims honor that lock, revalidate the set while holding it, and keep the lock through package replacement. Abort if the set contains any nonce other than the retained set. Locking only the individual claim or scan is insufficient because it leaves a gap before package replacement.

#4692) When "ocx service repair" re-registered the task through the elevated fallback, the spawn failed before UAC ever appeared: WindowsElevationError: ENAMETOOLONG: name too long, uv_spawn at startPowerShellCommand (src/lib/windows-elevation.ts:560) at runWindowsElevatedScheduledTaskRegistration (.../windows-elevation.ts:704) runWindowsElevatedScheduledTaskRegistration embedded the new task XML and the expected-existing snapshot as base64(utf16le) inside an inner PowerShell script, which was then base64(utf16le)-encoded again into -EncodedCommand. Two base64 layers over UTF-16 cost roughly 14.2 command-line characters per XML character, and a replacement carries two payloads, so a ~2 KB definition put the outer command past the Windows limit. On a host where Task Scheduler exports the trigger scope as an account name the re-register path runs on every repair, so repair could never exit 0. Both payloads are now staged to files and the command carries two paths and two 64-character digests, so its length no longer depends on the size of the XML at all. A file an administrator process will read is itself a privilege-escalation surface, so three properties hold together and none is sufficient alone: - Access. The staging directory is created fresh by mkdtemp and ACL-hardened through the existing hardenSecretDir/hardenSecretPath before anything is written into it, so the payload is private from the moment it exists. - No redirection. Each artifact is inspected with lstat and rejected unless it is what it claims to be. Exclusive "wx" creation inside a directory that did not exist a moment ago is the atomic step; the explicit check keeps that guarantee from resting on a reading of O_EXCL semantics. - Tamper evidence. The digest covers the exact bytes written, and the elevated script reads the file once, hashes what it read, and refuses before decoding. An ACL cannot cover this: a process running as the same user has the same SID and can rewrite the file, so the digest is what makes a swap during the UAC prompt fail closed instead of registering a different definition. Cleanup runs on every exit -- success, UAC cancellation, a synchronous spawn failure, a failed digest check, and a partial staging failure -- and a cleanup error is aggregated with the registration error rather than replacing it. The original "immutable bytes, never a caller-writable pathname" goal is kept by different means rather than abandoned, and the replacement precondition is untouched: the elevated process still re-queries the live registration and compares it to the verified predecessor before passing -Force. Payloads are UTF-16LE with no BOM and are decoded straight into Register-ScheduledTask, so what is hashed is exactly what is registered, with no trimming step the two sides could disagree about. Closes #4692
Staging the elevated Task Scheduler XML introduces exactly one new failure of its own: hardenSecretPath grants the staging account and strips inheritance, so a split-token elevation of the same user reads the file while an elevation answered with a DIFFERENT administrator's credentials does not. The inline form had no such dependency. The elevated process runs hidden, so nothing it writes survives and only the exit code crosses back. That made the failure an unexplained non-zero status -- the same undiagnosable shape as the ENAMETOOLONG this change set removes. The read failure now has its own protocol code, and the parent turns it into a message that names both the cause and the way out: approve the prompt as the signed-in user, or run again from a session already elevated as that user. The code sits outside OCX_ELEVATED_PROTOCOL_CODES, which is the create-and-run transaction's alphabet, and cannot collide with UAC cancellation. Whether to widen the ACL to SYSTEM and Administrators is left as a separate security decision rather than bundled here, because it changes a security-sensitive module.
…ce suite (#4692) The file-size ratchet failed: tests/service/service.test.ts has a committed cap of 4106 lines and the new staging cover pushed it to 4245. The ratchet only ever lowers baselines, so growing past a cap is the thing it exists to refuse, not something to re-baseline around. The cover moves to tests/windows/windows-elevation-spawn.test.ts, which is the better home anyway: its subject is the elevated registration payload, which is exactly what these tests exercise. That file has no cap and stays well under the 2000-line threshold, and the service suite returns to its baseline unchanged, so no new test file and no test-layout registration are needed. Also replaces a logical-assignment shorthand in the staging cleanup with the explicit form the surrounding code already uses. No behaviour change; folded in here rather than spending a separate CI cycle on it.
…ip ci] The lane's Windows evidence was contaminated by a defect it does not own. The dispatch run's windows 2/6 shard failed with nine assertions, all in tests/clients/desktop-app-restart-posix.test.ts, and the identical signature (same file, same nine line numbers) is present on the dev-only dispatch 34795291889 from 2026-09-14. It is fixed on dev by f79c147, which landed after this lane's base 3070d64. Verified by blob rather than by commit message: this tree carried src/codex/desktop-app/windows.ts at 863a200 (pre-fix) and dev carries c73e067 (post-fix). Merged rather than rebased so the stacked chain and its review history are preserved. dev is absorbed at the bottom layer and cascaded upward so each layer's pull request keeps showing only its own change; merging dev into the tip alone would have made the tip's diff carry every dev commit since the fork.
Propagates the dev merge from the layer below, including the Windows desktop-restart fix f79c147 that the lane's Windows evidence needs. Nothing in this layer changes; cascading keeps this pull request's diff limited to the schtasks decode.
Brings in the Windows desktop-restart fix f79c147 through the chain, so this lane's Windows evidence measures this lane. The previous dispatch at 6a2b148 had windows 2/6 fail with nine assertions, every one of them in tests/clients/desktop-app-restart-posix.test.ts and none touching anything this lane changes. The same nine failures, at the same line numbers, are on the dev-only dispatch 34795291889 from 2026-09-14, which is what identifies the defect as pre-existing rather than introduced here. The other eleven shards were green: test 1/4 through 4/4 and windows 1, 3, 4, 5 and 6 of 6. No [skip ci] here: this is the lane tip, and its run is the gate for all three layers.

…ardown fix(update): keep a history-preflight refusal from aborting the update (lidge-jun#4718)

Summary
On Windows, "ocx update" stopped the service, entered the pending shared teardown path, printed
Native restore refused: history_paginated_requires_native_writer, and then aborted withcould not stop the running proxy. The service was down, no listener was left, and the old package was still installed. Installing the same target by hand succeeded, which is what the reporter did.The refusal itself is correct and is unchanged. The Codex history preflight runs before the config half of the restore, so it returns an envelope whose
config,catalogandhistoryartifacts are allskipped— nothing was attempted.restoreSharedClientStateAfterStoprecognised only two shapes, a laterhistoryfailure and everything else, so the refusal fell through to "everything else",ocx stopexited 1, anddecidePostStopUpdateread 1 as a proxy that would not die. The reported lane isbin/ocx.mjs; the Bun updater imports the same decision module and had the same defect.The obligation genuinely is outstanding here: config and catalog were never restored, so the client still points at the proxy that just stopped. Reusing the existing history-only outcome would have discharged the receipt and lost that, so this adds a third outcome rather than widening the second.
CodexNativeRestoreResult.historyPreflightRefusalcarries the refusal as a structured reason. The artifact states cannot carry it on their own: an ownership refusal and a desired-state skip produce the same threeskippedvalues, and matching the human-readable message would put a safety decision on prose.ocx stopkeeps the receipt, says so on stderr, and exits 80. Eighty is deliberately not 79: seventy-nine means the teardown ran and only history metadata is pending, and a caller reading it discharges the obligation.pendingTeardownsAreExactlyconfirms the obligations left in the home are exactly the ones this run chose to keep. A quarantined receipt or a concurrent stop's claim falls back to exit 1, which is the pre-existing behaviour, so the fallback loses nothing that used to work.decidePostStopUpdatelets 80 past the teardown gate and nothing else. Surviving runtime records, a live proxy and an unreadable liveness probe abort exactly as before, because a history refusal is evidence about history and says nothing about whether the proxy is gone.History protection is not weakened anywhere:
preflightCodexHistoryInjectionis untouched, it still refuses before any config, catalog, manifest, SQLite or rollout mutation, and the backup manifest is still retained for review.This is the first of three stacked Windows lanes; it targets
dev.Closes #4718
Verification
No local test suite, single test file, typecheck, build or install was run — the repository owner prohibits it for this lane. Local verification is explicitly NOT RUN. Hosted CI on the lane tip is the only execution evidence, and the Windows job there is the only platform evidence that exists for this change.
Static verification performed:
