Motivation

  • Prevent a disconnected hub-issued data-plane token from being inherited by a detached standalone replacement process and unintentionally authorizing the new standalone proxy.
  • Keep independently configured operator credentials intact while removing only hub-issued admission tokens that match the disconnected client key fingerprint.

Description

  • Propagate the disconnected client token fingerprint through the machine API to the recycle path by changing scheduleStandaloneRecycle to accept a disconnectedTokenFingerprint and supplying state.tokenFingerprint at disconnect (src/client/machine-api.ts, src/client/machine-listener.ts).
  • Implement standaloneRecycleEnv(env, disconnectedTokenFingerprint) to clone and filter process.env, removing OPENCODEX_API_AUTH_TOKEN and OCX_API_TOKEN_FILE only when the admission token's fingerprint equals the disconnected fingerprint, and use that filtered env when spawning the detached child (src/client/runtime.ts).
  • Add focused tests covering fingerprint-based env filtering and preservation of independent operator credentials (tests/client-runtime.test.ts) and adapt an existing listener test to assert fingerprint propagation (tests/client-machine-listener.test.ts).

Testing

  • Ran the focused unit tests with the bundled Bun in node_modules using node_modules/.bin/bun test tests/client-runtime.test.ts tests/client-machine-listener.test.ts, and all tests passed (8 passed, 0 failed).
  • Performed full repository checks: node_modules/.bin/bun run typecheck and node_modules/.bin/bun run privacy:scan both succeeded.
  • Note: an initial run with an ambient older Bun binary produced an unrelated node:zlib export error; re-running with the repo-provided Bun binary resolved that and the focused tests passed as above.

release: promote dev into main for v2.32.1
# Conflicts:
#	package.json
[WRONG BRANCH] merge dev into main for the v2.33.0 release
Promotes the dev integration line onto main. The resulting tree is byte-identical
to origin/dev, including package.json at 2.34.0.

The package.json conflict is resolved to dev's side, NOT to main's stale 2.33.0.
Earlier promotions (lidge-jun#2553, lidge-jun#2507) kept the target's version so the release bump
would land on its own "release: vX.Y.Z" commit. That is no longer legal: this very
delta adds tests/release-version-line.test.ts, which fails when the in-tree version
sits behind the highest release tag. With v2.34.0-preview.20260827 now published,
2.33.0 orders behind it, so a promotion carrying the stale line turns CI red on
every shard that runs the suite.

The consequence for the release step is that scripts/release.ts skips the bump
(release.ts:568, currentVersion === version), so v2.34.0 gets tagged on this merge
commit rather than on a separate release commit. The workflow creates the tag itself
after publishing and validates expected-sha against the checked-out commit, so the
tag still names exactly the audited tree.
[WRONG BRANCH] promote dev onto main for v2.34.0
[WRONG BRANCH] promote dev onto main for v2.35.0
[WRONG BRANCH] promote dev onto main for v2.36.0
[WRONG BRANCH] promote dev to main for the v2.37.0 release
[WRONG BRANCH] promote dev onto main for v2.38.0
[WRONG BRANCH] promote dev onto main for v2.39.0
…rkflow call (lidge-jun#3262)

Both v2.40.0 release dispatches (33615174183 preview, 33615177849 main) died
at startup_failure: a workflow_call cannot grant its callee more than the
calling job holds, and dev-version-bump.yml's job declares contents+pull-
requests write. lidge-jun#3129 wired the call but never dispatched a release, so this
is its first live run. The caller job now declares exactly the callee's two
permissions; no other job in release.yml gains anything.

release: carry the release.yml permissions fix onto main for v2.40.0

P1 Badge Sanitize the Task Scheduler restart environment

When the client runs under the Windows Task Scheduler service, this filtered environment is never used because OCX_SERVICE=1 exits through the supervised branch first. In buildWindowsServiceScript (src/service.ts:1727-1758), OPENCODEX_API_AUTH_TOKEN is loaded once before :loop; after disconnect removes the token file and exits with code 1, the wrapper loops without clearing that variable and starts the standalone proxy with the disconnected hub token still active. Reload or clear the token within the wrapper loop, or otherwise communicate the sanitized environment to supervised restarts.

P2 Badge Preserve an independent token-file credential

If OPENCODEX_API_AUTH_TOKEN contains the disconnected hub token while OCX_API_TOKEN_FILE points to an independently configured operator credential, this deletes both variables solely because the environment token matches. The replacement therefore cannot let loadServiceTokenFromFile restore the operator credential and starts with no intended admission token. Check the referenced file's token fingerprint or only remove OCX_API_TOKEN_FILE when it identifies the disconnected service-token source.
