Replaces the April wreckage (fifteen 70-byte 'working' MIDIs, archived) with a proper pipeline: - lib/midikit.py: stdlib-only SMF format-1 writer + reader/verifier - lib/songkit.py: composition helpers (bar-grid score DSL with a 4/4 bar linter, OPL arps, driving bass, vibrato, drum patterns) - tunes/: three original tunes - DOS adventure theme (Dm/132), N64 ambient (G/72), chiptune racing (Em/152) - all with LOOP_START/ LOOP_END markers for game engines - tools/build_all.sh + tools/check_wav.py: generate, verify, render via timidity+FluidR3, fail on clipping/dead air - tests/smoke_test.py: round-trip verified against mido All three tunes render clean: no clipping, no dead air, durations match, chromaticism audited against the chord chart.
