The tag binds the document content hash and Merkle Mountain Range root to the authorship evidence chain, enabling blind extraction without access to the original.

Embeds an HMAC-SHA256 routing tag as zero-width Unicode characters at deterministic word-boundary positions selected via an HMAC-seeded Fisher-Yates shuffle, binding the document content hash and Merkle Mountain Range root for blind extraction. Changes from version 1: the symbol alphabet drops U+FEFF (a byte-order-mark hazard) for U+200B, U+200C, U+200D, and U+2060, consistent with the fingerprint normalization; and the tag is protected by a Reed-Solomon erasure code spread across surplus positions, so extraction recovers from partial loss of the zero-width characters instead of failing all-or-nothing.

Computes a deterministic, model-free 256-bit SimHash over a document's structural skeleton rather than its content words, so it survives synonym-level paraphrase that changes wording but preserves structure. From NFC-normalized text (zero-width and formatting characters removed, sentence and paragraph boundaries and punctuation preserved) it derives the sentence-length sequence, the paragraph-length sequence, the punctuation-class profile, and the closed-class (function-word) skeleton, and folds these weighted features into the hash. Because the features are model-free the value is reproducible by any verifier. Two fingerprints match when their Hamming distance is at most 24 bits (about 9 percent). Robust to synonym substitution, reformatting, re-encoding, and zero-width-character injection; not robust to heavy restructuring or translation.
