recordOwnedConfigPath(getConfigDir(), path) before resolveWriteTarget(path),
matching atomicWriteFile’s ownership registration. Add a regression test
covering the asynchronous write path and verifying the ownership record is

readPid, including verifyPidIdentity and the update job flows, to perform an
uncached process-identity check or bind verdicts to the current start-time
identity. Ensure recycled PIDs cannot approve foreign processes, and add a
regression test covering PID reuse.

- Around line 32-40: Add setOcxStartProcessProbeForTests to the test imports and
invoke it with null in the afterEach teardown alongside the other process hook

Record asynchronous writes in the ownership manifest.
atomicWriteFile registers path with recordOwnedConfigPath(getConfigDir(), path) at Line 105. atomicWriteFileAsync does not do this. An asynchronous write can therefore publish a managed file without its ownership record. Restore or cleanup code can then classify that file as foreign or untracked.
Add the same registration before resolveWriteTarget(path). Add a regression test for the asynchronous path.
Proposed fix
const effective: AtomicWriteAsyncIO = io ?? {
// ...
};
+ recordOwnedConfigPath(getConfigDir(), path);
const target = resolveWriteTarget(path);📝 Committable suggestion

Bind cached PID verdicts to process identity before termination.
isLikelyOcxStartProcess returns a cached true at src/config/process-state.ts:171-178. sweepDeadOcxStartProcessCache removes entries only after ESRCH at src/config/process-state.ts:140-163, so a recycled, live PID retains the old verdict. verifyPidIdentity at src/config/process-state.ts:221-227 can then approve a foreign process for termination. The update path also kills readPid() results directly at src/update/job.ts:876-880 and src/update/job.ts:1213-1218.
Bypass the positive cache for destructive checks, or bind each cached verdict to a process start-time identity. Route every destructive readPid() result through that uncached identity check, and add a PID-reuse regression test.

Add coverage for the snapshot-guarded cleanup and identity helpers.
The import list covers removePid and removeRuntimePort, but the module also exports removePidIfValueIs, removeRuntimePortIfPidIs, readAlivePid, verifyPidIdentity, and sweepDeadOcxStartProcessCache. None of them are exercised in this file.
removePidIfValueIs and removeRuntimePortIfPidIs are the TOCTOU guards that the linked issue names as must-preserve. src/cli/index.ts line 215 calls removePidIfValueIs(pidSnapshot) on the stale-owner path. A regression there deletes the PID file of a concurrently started replacement proxy, and no test in this cohort would catch it.
Add focused cases near the existing removal tests.
🧪 Proposed regression tests for the snapshot guards
test("snapshot-guarded pid removal keeps a replacement pid", () => {
writeFileSync(getPidPath(), "111", "utf-8");
removePidIfValueIs(222); // a replacement start rewrote the file
expect(existsSync(getPidPath())).toBe(true);
removePidIfValueIs(111);
expect(existsSync(getPidPath())).toBe(false);
// Absent pidfile is a no-op, not a throw.
removePidIfValueIs(null);
});
test("snapshot-guarded runtime-port removal keeps a replacement pid", () => {

Reset the process probe hook in afterEach as well.
The module exports setOcxStartProcessProbeForTests, which replaces the global ocxStartProcessProbe used by sweepDeadOcxStartProcessCache. The teardown at lines 33-36 resets the exec hook, the platform hook, the Windows resolver, and the cache, but not the probe.
This file never sets the probe today, so nothing leaks yet. The gap becomes a cross-test failure as soon as a sweep test is added here. Reset it now so the teardown covers every hook the module exposes.
