BSU-04 — HASH160 operand-width contradiction

Every current UTXO matching this deterministic predicate, seeded from an auditable UTXO snapshot and extended by the live canonical-block ledger. These are script-level classifications, not estimates of lost coins.

Exact predicate

An exact P2PKH-like or P2SH-like HASH160 comparison directly pushes a value not 20 bytes long.

Why it cannot be spent

HASH160 always produces a 20-byte vector, so equality to a differently sized vector is impossible.

Current primary-classification aggregate

Primary UTXOs–Primary value–

Each current output is counted once under its primary classification. Additional matching predicates remain visible in the table and are never added to the aggregate again.
