ACE-Step 1.5 Turbo — WebGPU model packages
Content-addressed model packages for the browser WebGPU port of
ACE-Step 1.5 Turbo, consumed by
FluidInference/fluidaudio-web's
/music page (runtime vendored at packages/acestep).
This is a byte-exact, SHA-256-verified mirror of the production tuple built by
the runtime's deterministic converter (model/convert.py --profile production)
and originally published by the port's author, Hamza Qayyum (Narcotic
Software) — see the original demo at https://acestep.narcotic.sh.

Every payload prefix and manifest filename is content-addressed and immutable; manifests carry per-file SHA-256s that the runtime authenticates before use. The direct manifest excludes the optional planner/semantic material.
