-- **Queue: `genesis` from a map doesn't check the owner-not-reviewer
-  rule.** Row 31 added the refusal to `add`, `set reviewers` and `assign`,
-  but a genesis map can still create a row whose owner is a reviewer.
-  No current row has that shape. Filbert, row 31 r1 (#1508 comment 26629).

 - **Queue: `add --issue N` also sets closes to N.** Follow-up rows under
   an umbrella issue, like rows 31 and 33 under #1508, would close the issue
   when they finish. Sage narrowed both by hand (revs 36 and 43). Either
   `add` takes `--closes` or the lead checks closes on every add. Not
   urgent while Sage adds the rows. (2026-10-04, #1508)
-- **Queue: the `assign` refusal calls the seat "owner" too early.** The
-  message calls the seat the row's owner before the assign makes it one.
-  Wording only. Filbert, row 31 r1. (2026-10-04, #1508)
-- **Queue tests: one unexplained failure on a cold start.** Darkwing's
-  first run of the D candidate in a fresh clone gave 141 passed, 1 failed.
-  The failing test's name wasn't captured. 15 reruns passed 142/0,
-  sequential and parallel. Darkwing suspects a timing bound, most likely
-  the 300 ms deadline case in the transport test, which allows 4000 ms.
-  That isn't confirmed. Next time: capture the name, then fix it as its
-  own patch. (2026-09-27, #1508)
 
-- **queue-commit.sh blames the guard when HEAD moves.** Step 7's canary
-  reads H into its index (`scripts/queue-commit.sh:94`). The hook diffs
-  against the live HEAD. If another queue commit moves the branch after H
-  is recorded, the clean canary sees a difference and refuses with "git is
-  not running the queue guard as installed". The fix it prints does
-  nothing. The refusal is correct, the message is wrong. Fix: guard_check
-  compares HEAD with H before the canary and says "HEAD moved since H;
-  start again". Filbert found this during the row 12 live round.

-- **Queue validator checks date shape, not the calendar.** `ISO_RE` and

-  future verb could. Fix: round-trip the parsed date. Filbert and

+- Queue follow-ups from rows 12, 13 and 31 (2026-10-04, #1508): closed by
+  row 33. Filbert built it, and Darkwing reviews it.
+  - `genesis` refuses a map row whose owner is one of its reviewers (exit
+    2, nothing written). The check is on the map, not in replay, so a log
+    from before the rule still loads.
+  - The `assign` refusal now reads "can't assign row N to SEAT: SEAT is
+    one of its reviewers".
+  - `queue-commit.sh` compares HEAD with H before each canary and again if
+    the clean run fails. A moved HEAD exits 2 with "HEAD moved since H was
+    recorded"; the guard message is kept for a real guard failure.
+  - Every time and date the validator accepts must format back to itself,
+    so month 13, day 32, 2026-02-30, 2027-02-29 and 24:00 are refused.
+    The live log at rev 45 still replays.
+  - The cold-start failure (2026-09-27): not reproduced in 20 cold runs.
+    Each ran `node --test packages/queue/tests/` in a fresh tree, 10
+    shared clones and 10 exports, one after another. All 20 passed
+    148/148 (2960 of 2960). The 300 ms deadline test is unchanged. Counts:
