The Bun CLI also checks for version skew before selected lifecycle commands and can print a bounded, best-effort notice.

Escape the literal pipes in the contract table.
The | characters in the Protection, Guidance, and Status cells are parsed as column separators, including pipes inside inline code. This breaks the three-column table and splits the contract expressions across cells. Escape the pipes as \| or move those expressions outside the table.
This matches the supplied markdownlint-cli2 MD056 findings.

Add the final PATH validation checks to the proposed implementation.
The r2 amendment at Lines 1109–1113 requires a Bun -e identity probe and rejects POSIX candidates whose file or parent directory is group- or world-writable. This implementation checks only file type, executable access, size, and --version. Its fixture also accepts any version output and expects only one probe. Update the implementation and fixtures so a candidate that fails either r2 check cannot pass this documented policy.

Use the accepted neutral notice text.
The r2 amendment at Lines 1116–1118 requires exact neutral text and says not to reuse computeVersionSkew().warning. This implementation reuses that warning, and the fixture asserts it. The plan notes at Line 1098 that the warning may suggest service restart. Replace it with the specified neutral text and update the assertion.

Add the provenance regression test to the focused verifier command.
030_launcher_bun_fallback.md:1076 omits tests/ci-workflows/bun-runtime.test.ts, although the r4 amendment explicitly requires it. The main verifier command in 031_wp3_execution_packets.md:17-20 already includes the test and needs no change.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick winValidate the PATH candidate's binary identity before selecting it.
findPathBunaccepts any executable that meets the size threshold and returns the pinned version for both--versionand-e. The focused fixture demonstrates this with a padded shell script. When bundled Bun is unavailable,bin/ocx.mjscan therefore select and execute that non-Bun file as the Bun runtime. This violates the documented binary-identity contract.Add a robust Bun identity check at this source boundary. Do not rely only on output matching.

Mark the WP5 guards as planned.
The reviewed head does not contain the WP5 command-guard implementation or its call sites. The planning record also states that this behavior remains pending until PR B lands. Update line 51 so it does not present the guards as shipped.

Summary
ocxfrom an npm, pnpm orbun linkinstall refused to start whenever the bundledbundependency was missing, even when a usable Bun sat on PATH. On the reporting Mac,~/.bun/bin/ocx(abun linkto a checkout withoutnode_modules) and the Homebrew/npm launcher both printedopencodex: thebundependency is not installedand exited 1, while~/.bun/bin/bun1.4.0 was right there. Separately, a stale CLI (2.7.43 on the same PATH) could drive start/stop/update against a newer running proxy without saying so.bin/ocx.mjs, newsrc/lib/bun-path-runtime.mjs): the order isOPENCODEX_BUN_PATH→ bundled Bun → the bundled installer's recovery → the first PATH Bun that passes validation → the existing failure. A candidate must sit in an absolute PATH entry (bun, orbun.exeon Windows; no shell, no.cmd). It must also be a regular executable that passesisRealBunBinary, and must not be group- or world-writable (file or parent, POSIX). Its--versionmust equal its ownBun.versionfrom a bounded-eprobe, and the version must be in the pinned dependency's line (same major, minor ≥ pinned:>=1.4.0 <2.0.0today). This is an execution-policy check and does not authenticate the binary. The selection is stamped asprocessprovenance, so service and shim builders reuse it instead of rediscovering PATH. The fallback prints one line (opencodex: using PATH Bun 1.4.0.), and no rejected path is ever printed./Applicationsor~/ApplicationsOpenCodex.app), so the user has a working command.src/cli/version-skew-notice.ts):start,stop,restart,updateandserviceprint one neutral stderr line when an identity-checked live proxy reports a different version. It uses a 200 ms budget, is skipped for--json/--help, and never changes the exit code. The npm/pnpm/mise update paths handled by the Node launcher are out of scope; they exit before the Bun CLI starts.Desktop-supervision status and guards are in #6802 and the guard follow-up; this PR is independent of them.
