14 August 2026: opening bank C1, from the math helpers to the battle windows
Bank $C1, the battle engine, is open. In one day it went from an empty file to 4,085 matched bytes: math and number formatting, the battle status bar and all its callees, the item and tech list renderers, and the per-frame window upkeep. 33 functions over sessions 34 to 40, plus a root-cause fix in the disassembler.
12 August 2026: the sprite-init system closes, and a first look at bank C1
The triple-slot routines, the dispatcher layer above the sprite-slot cluster and the animation queue that drives it are all matched, so the sprite system from $C98A to $E129 is one continuous run of matched code. Then a scouting pass over bank $C1, the battle engine. 3,509 new bytes in 10 functions (sessions 31 to 33).
