fix(codex): close the silent paths into a Codex lockout - #5288
Conversation
…block Codex The shim ran "ocx ensure" with both streams discarded and its exit status ignored, then launched Codex regardless. A proxy that failed to come up was therefore completely silent, and Codex started against injected routing pointing at a port nothing was listening on -- the #5261 shape, with nothing on screen naming opencodex. It now checks the exit status and prints one line on stderr when the start failed, naming "ocx doctor" and "ocx restore". Ensure's own streams stay discarded: it prints progress and warnings on exit-zero runs too, and a wrapper that leaked those would put noise in front of every ordinary launch, which is how a diagnostic gets ignored. The exit status is the signal, and the one line is the whole message. PowerShell had the opposite defect in the same place. An "ensure" that threw escaped the try/finally, which has no catch, so Codex never launched at all -- the autostart helper creating the exact lockout it exists to prevent. That path now catches, reports, and hands over to the real launcher, with Codex's exit status still authoritative. The Unix revision marker moves to 3 so installed Unix shims are detected as obsolete and regenerated. Windows shims have no revision marker and are excluded from obsolete-shim refresh, so existing Windows wrappers keep the old text until reinstalled; that gap is recorded in the lane document rather than papered over here. The new behaviour is covered by running the generated script against a stand-in ensure, in a sibling file because codex-shim.test.ts is close to its line cap and the cap only moves down. The test constants it kept as private literal copies now come from the source module.
A model_catalog_json naming a file that no longer exists does not degrade Codex, it stops Codex loading its configuration at all. That presents as the same blank wall as the dead routing in #5261 while having a different cause and a different fix, and it is the state the reporter's machine was left in after the catalog file was deleted by hand. Injection already repairs this: the chooser refuses a missing owned path and the caller strips the stale line. My earlier note that the pointer survived injection was wrong, and the end-to-end coverage for it already exists. What was missing is that the repair only reaches someone who runs opencodex again, and the whole difficulty of this state is that Codex is the thing that stopped working, so nothing prompts them to. "ocx status" now says it out loud, names the file, and offers both outcomes: regenerate the catalog with "ocx start", or take opencodex out of Codex with "ocx restore". Which one they want is their choice. A catalog the user named is left alone whether or not it exists, exactly as during injection. Claiming it would put opencodex's recovery advice in front of a problem that is not opencodex's to explain. An unreadable or absent config reports nothing rather than inventing a finding.
Applying the Codex integration writes routing that survives a restart, and then setup ends on "Setup complete". It does not install a background service -- that is a separate command -- so "routing written, nothing listening" is an ordinary state after the next reboot rather than a corruption. Nobody says so, which is half of why #5261 read as a Codex fault rather than an opencodex one. Setup now ends by reusing the existing restart-health model: when the install is restart-unsafe it prints what status and doctor already say about it, and names "ocx restore" as the way out that does not need the proxy back. It runs after the autostart choice, because that choice is what decides whether the warning applies, and a diagnostic that cannot be computed does not fail a completed setup. Deliberately not a Windows boot trigger. The scheduled task runs as the interactive user, so before logon there is no session for it to run in; adding a BootTrigger would read like a fix and change nothing. Making it genuinely pre-logon means a different principal and a different service backend, which is a larger change than this lane, and is recorded as such rather than half-done here.
The URL launcher swallowed its own failure and returned nothing, so the Codex login route answered identically whether a browser opened, failed to open, or was deliberately skipped. The CLI then printed the URL and started polling, and a user whose machine could not launch a browser sat watching something that looked like it was working. That is the account-pool half of #5261: not an error, a silence. openUrl now resolves a result instead of returning void. It still never rejects and never throws, because a browser that will not open is an inconvenience rather than a login failure -- the URL remains a valid thing to open by hand and the flow stays live. Callers that genuinely do not care say so with void. The Codex login response carries browserLaunch, and the CLI prints a recovery line only when the launch failed. It names the fixed callback port, because that is the part a user cannot work out alone: ChatGPT supplies the redirect URI, so the flow cannot move to a free port, and --device is the way around it. Existing tests mocked openUrl as returning void, which the awaiting caller would have read as a failed launch; all eight mock sites now resolve a result. The new test does not exercise the started case: the launcher command is fixed per platform, so proving it would mean opening a real browser on whatever machine runs the suite.
Explains why the four paths belong in one lane: none locks anyone out alone, and the incident is what happens when every signal is missing at once. Records two corrections rather than burying them -- lane H's claim that the catalog pointer survives injection was wrong, and a Windows BootTrigger is a fake fix given the task's interactive principal -- plus the three residuals this lane deliberately leaves open.

On a Linux host where xdg-open exists but cannot open a browser, such as a headless session without a display or registered handler, the child emits spawn and then exits nonzero. Resolving started on the spawn event therefore makes browserLaunch report success and suppresses the new recovery hint in exactly the failure scenario this change targets; observe the launcher's exit status with a bounded wait and map a nonzero exit to failed.

If the catalog is deleted while the proxy is already running, ocx start refuses at the live-owner check before reaching catalog synchronization, so this advice does not regenerate the missing file and leaves Codex broken. Recommend ocx sync here, or condition the advice on proxy state and explicitly instruct the user to stop/restart when necessary.

When a first-time user declines Codex injection but their existing Codex config points at a custom-local or unclassifiable local route, collectStartupHealth still returns at-risk, so setup claims that routing was written by this setup and recommends ocx restore even though opencodex did not install that route. Track whether injection actually succeeded or require health.routingInjected before printing this opencodex-specific warning.

Hosted CI failed on the guard that every test file bounding a spawned child with the internal deadline must declare whether it warms that child's module graph. The new shim test spawns children and did not. Recorded as unwarmed, for the same reason as the file it sits beside: its children are throwaway shell scripts standing in for ensure and for the real Codex launcher, so the cold cost is shell and process startup rather than a repository module graph, and an import scan has nothing to warm. The generated shim never loads a repository module in the child -- the point of the file is what the shell does with an exit status.
Blocker: the PowerShell shim test's Codex-failure fixture also exited 19 from ensure, which the wrapper now correctly reports as a failed autostart, so that phase no longer isolated a Codex failure and both PowerShell variants would have failed on Windows. Its ensure now succeeds, which is what the phase always meant. The setup warning said "nothing here will restart the proxy" for every restart-unsafe install. A healthy launcher shim is also restart-unsafe, because it covers CLI launches only, but it does restart the proxy for those -- and the summary line printed directly beneath said so. The warning now states the dependency without the false absolute, and a test pins that the shim case does not claim otherwise. The URL launcher resolved "started" on the spawn event, which only proves a process began. A launcher with no handler spawns happily and exits nonzero a moment later without opening anything, so a login could still report a launch that never happened. It now watches briefly for an immediate nonzero exit, which is how those failures arrive. "ocx gui" awaits the launch and says so when it did not happen. It still exits 0: the proxy is serving and the URL it printed is reachable, only the launch failed. The catalog finding is tagged (local) on its header like every other local-state line, so a connected client cannot read a finding about its own Codex home as something the hub reported. Catalog ownership stays decided by basename, now stated as a choice rather than left to look like an oversight: it is the same test injection applies, and a detector drawing the line elsewhere would report a state injection would then treat differently. Also removes the temporary directory the launcher test created, and corrects that file's header to describe what it actually covers.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Treat signal termination as a launcher failure.
Line 64 treats code === null as "started". A null exit code means the launcher ended by signal. If that occurs before the settle timer, the GUI and OAuth flows report a successful browser launch even though the launcher did not complete. Return "launcher-exit" unless code === 0.

Summary
Follow-up to #5267, which removed the dead end a user locked out of Codex hits. This takes the four paths INTO that state that #5267 listed as not closed. None of them locks anyone out alone; the reported incident is what happens when every signal is missing at once — a proxy that stopped, an autostart that failed silently, a reboot that restarted nothing, a catalog pointer naming a deleted file, and an account flow that looked like it was working. Each step had an explanation and the user could reach none of them.
The shim hid autostart failure, and on PowerShell could stop Codex launching at all. It ran
ocx ensurewith both streams discarded and|| true, then launched Codex regardless, so a proxy that failed to come up was invisible. It now checks the exit status and prints one line on stderr namingocx doctorandocx restore. Ensure's own streams stay discarded on purpose: it prints progress and warnings on exit-zero runs too, and a wrapper that leaked those would put noise in front of every ordinary launch, which is how a diagnostic gets ignored.PowerShell had the opposite defect in the same place. A throwing
ensureescaped atry/finallywith nocatch, so the real launcher was never reached — the autostart helper producing the exact lockout it exists to prevent, with a test asserting that propagation as correct. It now catches, reports, and hands over, with Codex's exit status still authoritative.A catalog pointer whose file is gone is now reported. Correcting my own note on #5267: injection does already repair this — the chooser refuses a missing owned path and the caller strips the stale line, with end-to-end coverage in place. The real gap is narrower and worse. That repair only reaches someone who runs opencodex again, and the whole difficulty of the state is that Codex is what stopped working, so nothing prompts them to. A
model_catalog_jsonnaming a missing file does not degrade Codex, it stops Codex loading its configuration at all: the same blank wall as dead routing, from a different cause.ocx statusnow names the file and offers both outcomes, regenerate or remove.Setup now says that routing outlives the proxy. Applying the integration does not install a background service, so "routing written, nothing listening" is an ordinary state after a restart rather than a corruption, and setup ended on a success line without mentioning it. It now reuses the existing restart-health model, so this cannot drift from what status and doctor report about the same install.
A Windows BootTrigger is deliberately not the fix here. The scheduled task runs as the interactive user, so before logon there is no session for it to run in; the trigger would read like a fix and change nothing. Genuine pre-logon start means a different principal and a different service backend.
A browser that never opened no longer looks like success. The URL launcher swallowed its own failure and returned nothing, so the Codex login route answered identically whether a browser opened, failed, or was skipped; the CLI printed the URL and polled while nothing had happened. Launch failure is now reported and still never fatal — the URL is worth opening by hand and the flow stays live. The recovery line names the fixed callback port 1455, because ChatGPT supplies the redirect URI so the flow cannot move to a free port, which is the part a user cannot work out alone.
Not closing #5261
Three residuals, each a separate change with its own risk:
ocx codex-shim uninstallthenocx codex-shim install. Unix shims regenerate on their own: the Unix revision marker moved to 3. Giving Windows a revision marker and a refresh path means changing a transactional install path that this lane cannot exercise, so it is named rather than attempted.Verification
ensure, not by asserting on template text: the property under test is what the shell does with an exit status. A failing ensure produces exactly one diagnostic and Codex still runs with its own exit status; a succeeding ensure produces nothing on either stream; an ensure whose launcher does not exist at all is treated as a failed start rather than dying with it.codex-shim.test.tsbecause that file sits close to its line cap and the cap only moves down. Registered in bothscripts/test-layout/layout.jsonandtests/fixtures/test-layout-expected.json, as is the new oauth test.tests/fixtures/file-size-baseline.json: no tracked file is over its cap.ocxexecution, service start or restart, and any change to credentials or configuration on this machine. The incident being fixed is a configuration change that locked a user out, so verification is static source review plus exact-head hosted CI on this branch.(local)tag while connected to a hub. All are fixed here.Checklist
Security review
This touches the login path, so stating it explicitly. No credential, token, account identifier or authorization URL is logged, serialized or added to any output by this change. The new login-response field is a three-value launch outcome carrying no user data. The recovery line is fixed text. A failed browser launch stays non-fatal and returns the same status code as before, so nothing becomes a login failure that was not one; making it fatal would turn an observable inconvenience into a lockout, which is the defect class this lane exists to remove. The launcher still never throws and never rejects, preserving the property that a headless host cannot kill a login flow. The shim diagnostic is fixed text on stderr and interpolates nothing; ensure's own output remains discarded, so nothing it prints can reach a terminal through the wrapper.
