Function isPushOpcode

packages/utils/src/fingerprint.ts:56–58

(opcode: Op)

// Note: libauth's isPushOperation also matches OP_RESERVED (0x50) — the spec excludes it.
export function isPushOpcode(opcode: Op): boolean {
  return isPushOperation(opcode) && opcode !== Op.OP_RESERVED;
}

// Encode a push count using the smallest possible push encoding.
// libauth's encodeDataPush minimally encodes VM Numbers in the -1..16 range as OP_N.
