Turn a raw disassembled 6809/6309 OS-9 module into legible, byte-identical source. Renames generic labels (L0047, u0100) to meaningful names, adds an inline comment to every instruction, fixes the disassembler's failures (code left as fcb data, data decoded as code, per-instruction address labels, direct-page globals resolved to code labels, addresses symbolized as immediates), and formats to the project style. Scales to huge modules by fanning out reader agents. Every step is verified byte-identical to the original binary. Invoke with a file path argument.
Annotate Motorola 6809 and Hitachi 6309 assembly source by adding clear comments to each code line and introducing sensible labels when labels are missing or weak. Use when Codex needs to explain, clean up, or reverse-engineer 6809/6309 assembly listings, ROM disassemblies, monitor source, game code, firmware, macros, data tables, or mixed code/data files without changing program behavior.
