-    @ maze entry logger: record lr/sp to mailbox 0x08006964, return 0.
-    @ Guard: if lr is outside known-good SBL/stub ranges, spin with
-    @ interrupts disabled instead of jumping into the void (post-mortem
-    @ via vec trap regs).
+    @ maze entry logger: ring-buffer of (lr,sp) at 0x08006964 (8 slots),
+    @ return 0. Guard: bad lr spins with IRQs off.
