refactor: sha256:b561b3dbe85d8f76917476655c0b39e77f247f795a9eb924ff614cdb550e505e · gabriel/muse

refactor(store): Phase 1 — extract raw I/O primitives into muse/core/io.py

Move all I/O primitives with no domain knowledge out of the 2571-line store.py god object into a new focused module:

muse/core/io.py — MAX_MSGPACK_BYTES, MAX_PACK_MSGPACK_BYTES, safe_unpackb, _read_msgpack, _read_msgpack_dict, write_text_atomic, zstd_decompress_if_needed, _zstd_compress, _ZSTD_*, _validated_store_parents, read_msgpack_file, _write_json_atomic, _write_shelf_header_atomic, _fsync_robust

store.py retains all domain types and business logic; it now imports the above from muse.core.io. All 15 source callers and 9 test files updated. Patches in tests updated to target muse.core.io.* since that is where the constants live at runtime. Fixes missing json/_json/tempfile/fcntl imports in store.py after extraction.
