v0.16.0

v0.16.0 (2026-08-17)

Feat

• engine: run the tick at 2kHz, and the DAC at two substeps
• engine: run the tick at 3.2kHz

Fix

• sim: copy the snapshot's length on import, not the struct's
• stepped: hold the level across the reshapings, not just up to them
• engine: keep the derived stepped caches out of the snapshot
• pll: stop the beat phase wrapping past a beat the counter has not reached
• stepped: remember what a slot offers, not just what a step shows
• stepped: pay for a step once, not once per tick
• dac: arm the transfer by hand, not through HAL
• dac: one substep, because four starved the engine outright
• dac: give the outputs a clock instead of the loop's leftovers

Refactor

• dac: drop what the register path made dead, and re-date the docs

Perf

• channel: memoise the alignment-period search on the ratio
