Module chunk 

Stream chunking + cross-chunk integrity hash for mk1 multi-string cards.

Per design/SPEC_mk_v0_1.md §2.6, the canonical bytecode is suffixed with a 4-byte cross_chunk_hash (= SHA-256(canonical_bytecode)[0..4]) before splitting into chunk fragments; the hash is verified at reassembly. This catches dropped, reordered, or substituted chunks that the per-chunk BCH layer alone cannot detect.

Structs

ChunkFragment

One chunk’s worth of split output: a parsed header + its fragment bytes.

Constants

MAX_CHUNKABLE_BYTECODE

Maximum canonical-bytecode length that can be chunked under v0.1.

Functions

reassemble_from_chunks

Reassemble canonical bytecode from a list of parsed chunks.

split_into_chunks

Split canonical bytecode into chunks, appending the cross-chunk integrity hash.
