SOURCE-DERIVED BUG FINDINGS

The C128 listing review identified several errors characteristic of generated
retro code:

- modern-style long variable names that collide under Commodore's two-character
  significance rule
- misunderstanding of graphics source arguments vs actual color values
- draw/erase source confusion
- shared arrays reused for permanent and temporary geometry
- keypress consumed before dispatcher-level exit test
- FAST selected where 40-column VIC-II visibility was expected
- malformed DRAW syntax in radar section
- off-screen trajectory math

The archive treats these bugs as part of the project history rather than hiding
the false starts.
