+- `[recurring]` **Execution-mode menu asked AGAIN despite the 2026-06-10 "mechanical
+  fix"** (2026-06-14): at the M1 (`public_dns`) plan handoff I presented the "1.

+  in this clone, its matcher doesn't match the wording the `writing-plans` skill actually
+  produces, or it isn't installed/active. The standing agreement is to **default straight
+  to subagent-driven without asking**. → verify the Stop hook exists and that its pattern
+  matches the real menu text (the skill scripts "Two execution options" / "Which
+  approach?"); if it relies on `.claude/settings.json` hooks that aren't active here,
+  that's the gap. 5th occurrence (06-05/06/09/10/14).
