 - Existing local `sync/upstream-remainder-20261102` contains provisional true merges through 13H (`84682e966b2df76d6eeb04655d5eabb7ee5833e7`) and an unresolved 13I merge with target `d1d8bbfa8fb52b0312dbbf1bf48b2787a7273a56`. Its Agent Run failed (`seal_failed`); preserve the unmerged worktree and inspect/resolve its conflicts only after reconciling its evidence. 13C–13H require independent review and qualification before advancing a dependent PR stack.
 - PRs #28 and #29 were closed after confirming their exact heads were ancestors of main; #27 was already merged. The main checkout's unrelated untracked files were preserved.
 - #2207 review: the two-file patch has the same stable patch ID as upstream merge `c80a2569995c44d7ad8522ea97e5944c4b5265be`. Its same-process fast paths avoid closing a second descriptor when a claim is already observed. A concurrent probe/acquire interleaving remains a review question: the registry check releases its mutex before the probe opens and closes the file, so a new claim could arise in between. Verify or eliminate that interleaving before treating the correction as complete. Do not infer test success from the interrupted worker builds.

+The canonical upstream audit remains `docs/UPSTREAM_308_CANDIDATE_AUDIT_20260912.md` (the filename is retained for stable links). PR25 documentation cleanup must preserve that authority and its existing references, either at this path or through a deliberate compatibility link; this receipt does not replace the canonical audit.
