"""Build the pinned model bundle for `wai.generate.spectral` — a deterministic,
INTEGER, byte-exact generative synthesizer (the `intent=create` analog of the
integer-exact codecs: generation whose output hash is portable, not similarity).

The "model" is small and committable: a fixed-point integer sine LUT plus the
generator's configuration. The float `sin()` is used ONCE here to bake the LUT;
the generator (Rust) reads only integers, so generation is byte-identical on
every machine. Pinning this bundle's sha256 + (prompt, seed, steps) pins the
output exactly — same inputs → same bytes → same hash, anywhere.
