+  `review-wave-4-fixes` gate: Finding 1 → `pg-fix-forwarder-reconnect`
+  (with the failed-connect test seam the gate's blind spot demands),
+  Finding 2 → `pg-fix-tx-wake` (retires F-1's engine arm), Finding 3

+  (the suite's wake-driven rows would otherwise inherit a hang-shaped
+  false failure); 3–7 may trail into wave 5's window if the
