New targets under tests/fuzz/, wired into Makefile FUZZ_TARGETS, each with a
seed corpus (parser seeds are real fixtures prefixed with a loader selector
byte):
- fuzz_audio_dsp SoundBuffer factories + 14 DSP effects + concat/mix.
Self-contained (CPU sample math, no device).
- fuzz_import_parsers TileSetFile/TileMapFile/LdtkProject. Loaders take a
path, so each iteration writes mutated bytes to a temp
file; OSError (IOError) is swallowed as an expected
parse-failure outcome.
- fuzz_texture_factory Texture.from_bytes/composite/hsl_shift byte ingestion.
Multiplication-overflow path documented as out of scope
(would OOM, not crash cleanly).
- fuzz_shader_bindings uniforms[] + PropertyBinding/CallableBinding lifetime,
target Drawable destroyed mid-flight (#270/#271/#277
pattern). Degrades to pure binding-lifetime fuzzing if
shaders are unavailable.
All four signature-validated against the live mcrfpy API before running.
