Encodes each text window with a pinned open embedding model under fixed integer (int8) inference and binarizes the unit-normalized vector to a 256-bit signature via seeded random-hyperplane LSH, so Hamming distance approximates cosine distance and semantically equivalent text yields low-distance signatures. The value is fully specified by the pinned model weights hash, tokenizer, pooling, quantization scheme, and projection seed together with published cross-platform reproducibility test vectors, so any verifier reproduces it bit-for-bit. Used as corroborating evidence, not a sole identifier: a semantic match is confirmed against a lexical or structural fingerprint before provenance is asserted. Robust to paraphrase and translation; insufficient signal on very short heavily paraphrased text. Part of the CPoE proof-of-effort authorship attestation system implementing draft-condrey-cpoe-protocol.",
