Module opcode 

Stable opcode vocabulary shared by every Harn execution target.

This is the bytecode ABI’s single schema. Numeric discriminants and operand layouts are versioned artifact data, not implementation details. Consumers must use Op::operands instead of maintaining byte-width tables.

Enums

Op

OperandKind

One encoded operand in a Harn bytecode instruction.

Portability

Constants

OPCODE_ABI_ARTIFACT_VERSION

Artifact format version whose golden opcode fingerprint is pinned below.

OPCODE_ABI_FINGERPRINT_V1

Golden BLAKE3 digest of opcode bytes, names, and operand-role tags for v1.

Functions

opcode_abi_fingerprint

Compute the fingerprint of the compiled opcode schema.
