The same pure-i64 Rust that decodes the conditional codec natively compiles straight to wasm32 and runs in the browser engine with NO ML runtime — and its RGB is byte-identical to the native reference. A SOTA-class learned image codec (PTQ of mbt2018_mean) decoding deterministically in-page, verifiable against a pinned hash: the integer-entropy contract, in-browser. - decodeIntHyper(g_s, h_s, entropy, bitstream) -> DecodedImage: parses the model JSONs + bitstream, runs int_hyper_synth::decode_conditional (factorized z → integer h_s → integer-σ entropy → integer g_s), returns RGB. No float, no ONNX. - demo/verify_int_hyper_wasm.mjs + .sh: build the nodejs-target pkg, decode, and FNV-1a the RGB against the native cond.json hash. Verified: wasm32 reproduces adeb12d347d0bf7e (256x256, 42.61 dB) == native — zero JS ML runtime. The g_s/h_s model JSONs are large (PTQ weights), so they are NOT committed; the verify reads the export tool's artifacts (default /tmp/sota_int), exactly like the native int_hyper_synth test. pkg-node/ is a build artifact (gitignored).
