+30. **CHAT-03 rescoped against Gate E.** Dewey's r3 (BRIEF.md 2c5be6b4,
+    1,527 lines; packet e197b882, "Gate E map") marks each section for Gate
+    E. Rulings:
+    - Goal: option (a). A seat bound to the Console runs without the goal
+      extension, and Jason drives its turns. Goal continuation is a CHAT-06
+      item. Options (b) and (c) are refused: (b) is new machinery, and (c)
+      makes interrupt useless. A launch without the Console keeps goal as it
+      does today. The change is one launch flag and is reversible.
+    - Cut from CHAT-03: §7 Pi native dialogs, §5 H5–H8 on Pi dialogs, C-1,
+      C-2 and C-4. No repository Pi seat raises dialogs, and the interim
+      rule already counts unknown events.
+    - §2's idle drift check moves to CHAT-07. The live-session guard stays
+      and keeps CHAT-03 off real sessions until CHAT-07 lifts it.
+    - C-5 moves to CHAT-04 with its own contract review. CHAT-04 comes before
+      Gate E anyway. Without C-5, an interrupt that races a completion ends
+      in a force stop, which costs time but is safe.
+    - C-3 only if B1 finds a gap. I3 (a recording that calls a model or
+      reads Claude auth) still needs Jason's go. Sage asks when B1 is next,
+      not before.
+    - Filbert and Rocko review r3 only on the sections Gate E needs. A
+      finding in a cut section is not blocking. After r3, Dewey removes the
+      cut sections instead of rewording them.
