Summary

Closing record for the 260819 unclaimed-bug unit — five PRs now on dev (#2116, #2117, #2118, #2121, #2126). Documentation only; nothing in the build, typecheck, or test path reads from devlog/.

It leads with the two defects our own work introduced rather than the four fixes, because those are the parts worth not repeating:

It also records what is not verified: the Windows ACL half and owner-unavailable are unproven on Windows, #1933's diagnosis is inference from a display name rather than a posted path, #1527's other four residuals depend on #2054, and wp1587 is ready rather than done. Stated rather than filed as complete.

Verification

bun run privacy:scan   exit 0

privacy:scan does read devlog/, which is what makes a public devlog safe rather than merely visible. No code paths touched, so the suite is unaffected.

For the record, the state this documents: dev full suite on ssh lidge at the merged head is 13,505 pass / 15 skip / 0 fail across 855 files, with cross-platform CI green.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds a closing outcome record for the unclaimed-bug unit. It records PR dispositions, two discovered defects, validation evidence, unresolved follow-up items, and final suite and CI results.

Lists unresolved Windows, diagnostic, residual, phase-two, and tool-catalog work. Reports 13,505 passing tests, 15 skips, zero failures across 855 files, and green cross-platform CI.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 49f08

The PR only adds documentation and does not change build, test, or runtime behavior. It is mergeable with explicit owner follow-up to improve remediation traceability, make the baseline comparison reproducible, and qualify the cross-platform CI statement; these are bounded auditability issues rather than production-impacting defects.

**A credential written world-readable.** #2107 made service definitions
credential-bearing (a proxy URL routinely carries `user:password`) while they
were still written with a bare `writeFileSync` — 0644 under umask 022, measured.
In a file where the API token and install state already use 0600, and in a repo
whose `collectProxyEnv` deliberately reports proxy presence as a boolean so the
URL never escapes.

The second one merged. It was caught only because the final audit asked a
question the author never asked — *what mode is that file?* — and then measured
instead of reasoning.

Identify the remediation for the permission defect.

The record reports a measured 0644 mode and then states, “The second one merged.” It does not identify the affected service-definition file, the remediation PR or commit, or the observed post-fix mode.

Add those details. This record should show which credential-bearing file was corrected and what permission was measured after the fix.

- **Running the suite the way CI runs it.** Per-suite local green missed the leak
entirely, because the defect only exists across suites in one process.
- **Removing our commits.** The same two files on `origin/dev` went 144 pass / 0
fail. That is what converts "CI is flaky" into "we broke it".
- **An auditor that re-derives rather than re-runs.** Round 1 returned fail on
#2121's design; the final round found the P1 and mutation-tested our
assertions in a scratch tree to prove they were not vacuous.

Make the baseline comparison reproducible.

The phrase “same two files” does not identify the files, revision, command, or environment used for the 144 pass / 0 fail result.

Record the exact file paths, commit, test command, and runner scope. This will distinguish the baseline run from the full-suite result during later audits.
