+- **Queue validator checks date shape, not the calendar.** `ISO_RE` and
+  `DATE_RE` accept month 13, and V8 turns 2026-02-30 into March 2 without
+  an error. The CLI can't write such a value today; a hand edit or a
+  future verb could. Fix: round-trip the parsed date. Filbert and
+  Darkwing, Piece E round 2. (2026-09-27, #1508)
+- **Ledger metric call can orphan curl.** The metric call in
+  `packages/ledger/src/ledger.mjs` still relies on execFileSync's
+  timeout, which kills the helper but can leave curl running. E's queue
+  calls already use `timeout -s KILL`; the metric call should match.

+- **Ledger: a missing `timeout` command reads as a Gitea failure.** With
+  no `timeout` on PATH the queue issue calls report "credential or Gitea
+  request failure". Optional test and clearer message. Filbert, E r2.
