fix(codex): bind CLI update plans to installation content and pre-dotenv transport - #7546
Conversation
Carried onto the content-binding change from #7540. The launcher captures the proxy/CA map once beside the other pre-Bun values, so it counts against the required part of the launch-context budget before the optional HOME and NODE_PATH lookup seeds. The launcher transport fixture now supplies an install content digest, because a plan without one refuses before any npm query. (cherry picked from commit 60b1be2)
Derive codexCliUpdateBoundEnv's replaced keys from the launcher allowlist (CodeRabbit on #7513), so capture, parsing and the npm child cannot drift. Reconcile the two carried changes' tests: the source invariants now name the merged launcher text, the native retarget seam compares canonical paths (macOS temp roots sit behind /var -> /private/var), and the real npm-global plan test binds on the reported content digest, comparing plan ids only when the host has no live Codex session for the session scan to refuse on.

The carried content-binding path still rejects the current published Linux x64 package because its executable exceeds the native-file size bound. This was found by streaming the official artifact, verifying its SHA-512 against registry metadata, and reading its TAR headers; no package was installed or executed. The targeted finding below needs a bounded-size correction and regression coverage. The existing synthetic npm fixture does not cover this published-artifact size.
Content observation picked the platform backing by Bun's process.arch. A Bun override or the PATH fallback can run another architecture under Rosetta, so the observer could hash a backing Node would never execute (Codex review on #7546). The Node launcher now records its own arch in the proof-bound inspection snapshot; the context parser accepts only known Node architectures, keeps an absent value null, and fails closed on anything else; and the inspection deps forward it. Also make the npm-global test's Bun precondition real: fall back to the running Bun and assert a string (CodeRabbit on #7546). Co-authored-by: Epinephrine <luvs01@hanmail.net>
@openai/codex@0.163.0-linux-x64 ships a 296,865,480-byte native binary, above the former 256 MiB MAX_NATIVE_BACKING_BYTES, so a normal Linux x64 install could only refuse with install_content_unverified (review by @luvs01 on #7546). The binary is streamed in 1 MiB chunks, so the bound limits read time rather than memory; 1 GiB keeps it finite with more than 3x headroom. A sparse-file regression binds the published size and refuses one byte past the bound before any read. Co-authored-by: Epinephrine <luvs01@hanmail.net>

The original published-binary size finding is addressed by 1d0d3c1: the finite 1 GiB bound accommodates the verified artifact and the reader remains chunked. One related Linux-only regression still uses the former overflow size, as noted below. Please update that fixture and verify the Linux refusal/descriptor case along with the new published-size case. I have not rerun those POSIX tests locally.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick winFix the oversize fixture to exceed the 1 GiB limit.
The Linux descriptor-leak test creates a 257 MiB regular file, but
MAX_NATIVE_BACKING_BYTESis 1 GiB. The file therefore passes the size guard, reaches native content observation, and can produce a digest instead of satisfyingexpect(report.installContentDigest).toBeNull(). This makes the ordinary Linux test suite fail. Increase the sparse fixture above the configured bound.Suggested fix

Reviewed at 33ab461. The finite streaming bound now accommodates the published native backing, and the oversize refusal fixture derives its size from the same bound. Both the published-size and descriptor-refusal regressions passed in the current-head Linux test job: https://github.com/lidge-jun/opencodex/actions/runs/39846025553/job/120072253554
My reported blocking findings are addressed. The aggregate CI check is still queued and must complete before merge.

Summary
This carries two changes by @luvs01 into one PR, because both rewrite the same launcher snapshot and conflict when applied separately.

Plaincheckcalls still skip content hashing.HTTP_PROXY,HTTPS_PROXY,ALL_PROXY,NO_PROXY,NODE_EXTRA_CA_CERTS, any casing) before Bun loads project dotenv. The npm evidence queries use only that captured map. Before, a project.envcould redirect registry evidence through a different proxy or CA bundle.Before:
ocx system codex-cli-update planrun in a project whose.envsetHTTPS_PROXYsent its npm queries through that proxy, and a same-length edit to the installedcodex.jsproduced the sameplanId. After: the npm queries use the shell's pre-dotenv settings (or none), and the edit produces a differentplanId.Supersedes #7540 and #7513, carried from #7540 head

The transport map is now captured once, beside the other pre-Bun values, and is part of the required snapshot. It counts against the budget before any optional seed, and both serializations carry the identical map.

Under fix(codex): bind CLI update plans to observed installation content #7540, a plan whose inspection reports no content digest refuses before any npm query. Without the digest, all four transport cases fail (verified red, 0 pass / 4 fail), because they assert three npm queries.dev, on macOS; fix(codex): bind CLI update plans to observed installation content #7540 was verified on Windows and Ubuntu):a launcher retargeted during the native observation refuses: the seam comparedrealpathSync.native(path)against a lexical path. macOS temp roots sit behind/var -> /private/var, so the swap never fired. The test now compares canonical paths. Production code is unchanged.plan identity binds the bytes a real npm-global install placeduses the real process scan, which refuses withblocked_active_sessionon any host running Codex. That refusal is intended product behavior, so I did not add an environment switch to bypass it, since a project dotenv could use one. The test now binds oninstallContentDigest, which every plan reports, refused plans included. It compares plan IDs whenever both runs found an idle host, as on CI. The removed-backing refusal precedes the session scan and is asserted unconditionally.process.arch. Under Rosetta, a Bun override or the PATH fallback can run a different architecture than the Node that executesbin/codex.js. The Node launcher now records its ownprocess.archin the proof-bound snapshot. The parser accepts only known Node architecture names and keeps an absent valuenull, which falls back to the previous behavior. Any other value invalidates the context.@openai/codex@0.163.0-linux-x64ships a 296,865,480-byte binary, above fix(codex): bind CLI update plans to observed installation content #7540's 256 MiBMAX_NATIVE_BACKING_BYTES, so real Linux x64 installs could only refuse. The bound is now 1 GiB: finite, with more than 3x headroom over the largest published binary. Reads stay chunked at 1 MiB, so memory use does not grow, and a file over the bound is refused byfstatbefore any read. A sparse-file test binds the published size and refusesbound + 1. The Linux-only descriptor-refusal fixture now derives its oversize from the constant instead of hardcoding 257 MiB (also @luvs01).ocx-launcher-sourceandcodex-cli-update-launcher-policyeach pinned the other PR's pre-merge launcher text.
