+    - **Full open-issue page.** mosaicstack/stack has 50 or more open
+      issues, so under 8.10's rule every run is `incomplete`. Relaxed. A
+      full page makes the queue issue checks incomplete only when some
+      wanted issue is left without a known state. Truncation can't hide a
+      violation. Since 8.10, an issue absent from the open list is looked
+      up, and closed needs positive evidence. A truncated issue is either
+      looked up or left `unknown (budget)`, and `unknown (budget)` already
+      makes the run incomplete. Darkwing adds the change and a test to E
+      before the commit, and Filbert's round covers it. Filbert amends
+      8.10's budget table, as with C1.
+    - **Row 7's brief.** Sage re-pins row 7 with `set 7 brief` in the
+      queue commit after E lands. That keeps `verify --current` clean.
+    - **Row 7 stays for now.** This amends Q9. Q9 had row 7 leaving the
+      queue. Row 7's gate belongs to Jason, and closing a Jason-gated row
+      needs his cited approval, so the lead can't retire it alone. E puts
+      the weekly routine in the ledger README anyway. Row 7 retires when
+      Jason closes it.
+    - **Age from 2026-09-28.** The rule stays. Rows 9, 10 and 11 wait on
+      Jason, and row 13 can't finish before them. Monday's run will list
+      all four as age violations. That's true, and it points at Gate G.
+      Sage asks Jason for Gate G rather than weakening the check.
+    - **T3 seats.** The weekly run passes `--unsupported-runtime` for
+      each T3 seat that owns an active row, and the output prints it.
+      That matches 8.10's `exempt` class.
