// anchor_mathlib5.mjs — Anchor the MATHLIB5 paper seals into SnapKitty Chain.
//
// Reads the crypto seals produced by paper/mathlib5/full/anchors/, builds a
// UnifiedWitness whose worm_hash is the MATHLIB5 source fingerprint, mines a
// block so the witness is anchored at a real chain height, and writes a
// settlement record. The WORM seal lives in .chain/mathlib5/chain.json.
