Summary

#8534 made an interrupted Windows update clear its marker by itself, but only for markers written from then on. A marker left by OpenCodex 2.100.x or earlier records no installer supervisor. It still reads as uncertain forever, so every ocx update and ocx sync keeps refusing with update-in-flight, and users have no way to tell why (#8524). The coordinator chose to leave that behavior unchanged and add recovery guidance (option A): no automatic release and no new command.

When the inspection that refuses finds an unconfirmed installer with no witness, the fence has passed and every recorded process is gone, the refusal now prints the marker path and a reversible rename after the unchanged update-in-flight line:

opencodex: update-in-flight
The update marker C:\Users\<user>\.opencodex\update-orchestrated.json records an interrupted update whose installer can no longer be checked
(OpenCodex 2.100.x and earlier did not record the Windows installer), so it will not clear by itself.
If no update is running (no ocx update, no npm, pnpm or bun global install, no OpenCodex installer
PowerShell process running npm-install-job.ps1), rename the marker and run ocx update again:
  ren "C:\Users\<user>\.opencodex\update-orchestrated.json" update-orchestrated.json.stale
  • inspectUpdateMarker reports this case through an optional detail out-parameter. Its return value and every primitive call are unchanged. The fact comes from the same inspection that refused, so the marker is read once.
  • staleUpdateMarkerHint(home, platform) only formats text. On POSIX it prints mv -n with single-quoted paths, so nothing in the pasted command expands. On Windows it prints ren only when the path is printable ASCII without $, backtick, %, ", !, [ or ]. PowerShell also closes a string on typographic quotes and expands brackets as wildcards, so any other path gets no command, only the file to rename. A control character is masked in the message and suppresses the command on every platform.
  • ocx update (npm and Bun launchers): the legacy session start() adds a non-wire staleMarker: true only when the marker branch refused. The result-channel record is unchanged, and a refusal by a busy mutex prints no hint.
  • ocx sync: only the two marker-refusal branches pass the hint to refuseSync. The reason stays the first stderr line, and the JSON document and exit code 7 are unchanged.
  • Unchanged surfaces: the dashboard, Desktop, orchestrated and Remote Link paths still report only update-in-flight; the docs tell the user to run ocx update in a terminal.
  • Docs: troubleshooting/update-failed.md gains "If every update and sync says update-in-flight", in English and the existing Turkish page, with the safety checks before renaming. reference/cli/lifecycle.md links to it, and structure/ops/service-and-sidecars.md describes the hint.

Refs #8524

Verification

  • New cases in tests/update/update-windows-installer-witness.test.ts:

    • detail.witnessless is set only for the witnessless case. It stays unset when the supervisor is recorded, the launcher is live, the fence holds, or the launcher probe fails with a permission error.
    • The hint shows the Windows ren or POSIX mv command, and a Windows-shaped marker read on POSIX gets mv.
    • The session sets staleMarker only for a witnessless refusal, not inside the fence.
    • An ocx sync guard subprocess refused by a legacy marker prints the reason first and then the hint, exits 7, and leaves the JSON byte-identical.

    Fail-first: on dev the file fails because the export is missing.

  • tests/update/update-orchestrated-session.test.ts: the existing "prior installer marker refuses" case now expects staleMarker: true for its witnessless failed marker, and the unchanged result for the live-installer marker.

  • bun test tests/update: 1044 pass, 0 fail.

  • bun run typecheck, bun run privacy:scan and bun run structure:check pass, as do the docs link targets, test-layout, the file-size ratchet and the Lab boundary.

  • The bin/ocx.mjs import row and a new src/update/index.ts import row were added to tests/helpers/update-import-policy.ts. No primitive moved, so the pinned control contracts are unchanged.

NOT RUN:

  • A real Windows device; there is no Windows checkout on this host.
  • The parser-backed update lint, which runs only in the Windows lane.
  • The docs-site build.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

…usal

OpenCodex 2.100.x and earlier never recorded the Windows installer supervisor,
so a marker they left after an interrupted update can never clear by itself and
every later ocx update and ocx sync refuses with update-in-flight (#8524).
Behavior stays unchanged. When the refusing inspection finds an unconfirmed
installer with no witness, the fence passed and every recorded process gone, the
refusal now prints the marker path and a reversible rename after the unchanged
update-in-flight line: ocx update through a non-wire staleMarker flag from the
session start, ocx sync through refuseSync. The sync JSON document and exit
codes are unchanged. docs-site troubleshooting covers the safe recovery.

Walkthrough

The change identifies witnessless update markers and adds recovery hints to qualifying ocx sync and legacy update refusals. The hints provide platform-specific rename commands. Documentation and tests describe and verify the refusal details and recovery guidance.

Changes: Stale marker classification and sync refusal

Layer / File(s) Summary
Marker inspection and sync refusal
src/update/sync-update-mutex.mjs, src/update/sync-update-mutex.d.mts, src/cli/sync-update-guard.ts, tests/update/update-windows-installer-witness.test.ts
Marker inspection identifies an unconfirmed marker without an installer witness as witnessless. Sync refusal can print platform-specific rename guidance after the refusal reason. Exit-code selection and JSON output remain unchanged. Tests cover the classification, hints, and sync output.
Legacy update refusal reporting
src/update/orchestrated-session.mjs, src/update/orchestrated-session.d.mts, src/update/index.ts, bin/ocx.mjs, tests/update/update-orchestrated-session.test.ts, tests/helpers/update-import-policy.ts
Session startup adds staleMarker: true to qualifying refusals. The update command and launcher print recovery guidance when that flag is set. Tests cover the flag and the import updates.
Recovery guidance documentation
docs-site/src/content/docs/reference/cli/lifecycle.md, docs-site/src/content/docs/troubleshooting/update-failed.md, docs-site/src/content/docs/tr/troubleshooting/update-failed.md, structure/ops/service-and-sidecars.md
The documentation describes marker cleanup conditions, terminal recovery guidance, and safeguards before renaming a marker. It also records the behavior of markers without installer witness data.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Low · up to f55a9

This adds a reversible recovery hint when an old update marker blocks ocx update or ocx sync; existing refusal behavior is unchanged. The remaining issues are narrow. The checklist omits Bun global installs, the hint can appear for a marker whose launcher process is still alive, the Windows command needs a Command Prompt label, and one documentation sentence overstates when the hint prints. These should be fixed soon but do not make the change unsafe to merge.

POSIX quotes the path in single quotes and uses mv -n; on Windows a path with an expandable or control character gets no command, only the file to rename. The hint and docs also name bun global installs and the npm-install-job.ps1 supervisor. The test uses a pid no host hands out.

Refs #8524
PowerShell also closes a string on typographic quotes and globs brackets, so a Windows path gets a ren command only when it is printable ASCII without $ ` % " ! [ ]. A control character is masked in the message and suppresses the command on every platform; the explanation line is platform-specific.

Limit the hint claim to qualifying markers.

An older marker can cause refusal while its fence is active, a recorded process is alive, or a probe is inconclusive. Those paths do not set witnessless and do not print recovery guidance. State the qualifying conditions here and in docs-site/src/content/docs/troubleshooting/update-failed.md Lines 111–115 and its Turkish translation Lines 87–92.

As per coding guidelines, “Document current shipped or intentionally pending behavior.”

PowerShell does not expand %USERPROFILE%, so this command fails when pasted into a PowerShell terminal.

Include Bun global installs in the safety check.

A Bun global install can still be running when the user renames a witnessless marker. Retrying ocx update can then overlap that install.

Check the launcher before reporting a witnessless marker.

For a terminal failed marker, Line 165 omits marker.pid from the probes. A marker with pid: process.pid, phase: "failed", and terminationUnconfirmed: true therefore sets witnessless even while that recorded process is alive. This contradicts the recovery guidance, which says a marker with a running recorded process does not print the hint.

Probe the launcher before setting this detail, and retain the unknown result when its liveness cannot be determined.

Maintainer judgment (bundle lane: #8524 follow-up, coordinator decision A)

Value. Users stuck behind a marker left by OpenCodex 2.100.x or earlier now learn what blocks every ocx update and ocx sync, where the file is, and how to move it safely. Before this, the only output was update-in-flight, and the only recovery was renaming a file nobody knew about.

UX change. Text only, on stderr. A refusal caused by an unconfirmed installer marker with no witness (fence passed, every recorded process gone) now prints the marker path and a rename command after the unchanged update-in-flight line. Exit codes, the ocx sync --json document and the orchestrated result record are unchanged. A busy mutex, an active fence, or a live or unprobeable process never prints the hint. The dashboard, Desktop and Remote Link still report only update-in-flight; the docs send users to a terminal.

Existing users. No decision changes. inspectUpdateMarker returns exactly what it did before and only fills an optional detail. Remote Link Homes classify a Child by exit code and never read its stderr.

Windows impact. The copy-paste command is ren "<path>" update-orchestrated.json.stale. It is printed only when the path is printable ASCII without $, backtick, %, ", !, [ or ], so neither cmd.exe nor PowerShell can expand or split it; that includes typographic quotes. Any other path gets "rename that file by hand". POSIX gets mv -n with single-quoted paths. Control characters are masked in the message and suppress the command. The docs list what to check first: no ocx update, no npm, pnpm or bun global install, and no PowerShell running npm-install-job.ps1.

Verification.

  • New cases in tests/update/update-windows-installer-witness.test.ts:

    • detail positives and negatives;
    • the hint on win32, POSIX, a Windows-shaped marker read on POSIX, and paths that must get no command;
    • session staleMarker only on a witnessless refusal;
    • an ocx sync guard subprocess with reason, hint, exit 7 and byte-identical JSON.

    Fail-first on dev: the export does not exist.

  • bun test tests/update: 1044 pass, 0 fail, at the first head.

  • Typecheck, privacy:scan, structure:check, docs link targets, test-layout, the file-size ratchet and the Lab boundary all pass.

Reviews.

  • Round 1: general APPROVE and SECURITY APPROVE at f55a926b4a. Their hardening was applied in 013ebae39b.
  • Round 2: fresh REQUEST CHANGES at 013ebae39b, because PowerShell typographic quotes could split the command; security still APPROVE. Fixed in 24dfd23b0d with a printable-ASCII allowlist.
  • Round 3: fresh APPROVE and SECURITY APPROVE at 24dfd23b0d.

NOT RUN.

  • A real Windows device and PowerShell; there is no Windows host or pwsh here.
  • The parser-backed update lint, which runs only in the Windows lane.
  • The docs-site build. CI gates and test changed were still running at merge.

Residuals (optional, not changed).

  • * and ? pass the Windows allowlist. NTFS forbids them, so they are reachable only through \\?\\, and the worst case is a failed rename.
  • The Windows wording blames 2.100.x even though a current release killed before it records the supervisor leaves the same shape (no installer has run then).
  • The POSIX hint mentions npm-install-job.ps1, which only exists on Windows.

Refs #8524. The issue is already closed by #8534. #7815's synchronous writers, #7771 Option B and #7297's remaining scope were not touched.
