Source: TODO.md §8 (at 9151438)

Measured as a replacement for src/convert.c on the CI mutation path and scored below the gate
of 65 -- a real gap rather than a reason to skip the file.

Almost every survivor is in akbasic_audio_state_init, where nothing asserts that a freshly
initialised audio state is actually zeroed and defaulted. That is the same gap this job's history
records closing for src/symtab.c, and closing it is what earns the file its place back in CI.

Worth knowing before reading any score here: the harness's ICR operator only rewrites the
constants 0 and 1, so a lookup table of other values produces no mutants at all and a high
score over one says nothing about whether its entries are right. tests/audio_verbs.c asserts all
32 ADSR entries anyway -- that catches a hand-edit typo, which is the real failure mode, but it did
not and could not move the mutation number.

Files: src/audio_tables.c, tests/audio_verbs.c, .gitea/workflows/ci.yaml
