Bank tracking verified live (1512 switches); the zero source narrows to the RAM display list

Asteroids f=800: bank=1, switches=1512 (~1.9 per frame — exactly the kernel-in-bank-0 / logic-in-bank-1 per-frame rhythm), last switch at $11FF0 (the bank-0 SwitchTo1 stub). The F132 cross-bank-data-read suspect is REFUTED: reforge_active_bank tracks faithfully (the lifted STA $FFF8/$FFF9 hotspot writes execute ~twice per frame), so bank-aware mem_read8 (F38) serves correct bytes to each bank's code.

Raw traces, ROM material, local paths, and personal data are not part of this public record.
