# ic-memory v1 Wire Fixtures

These fixtures pin the 0.6 durable wire shape.

Files ending in `.hex` contain lowercase hexadecimal bytes. Tests decode the
hex into the actual durable bytes, recover or validate them, and re-encode the
current output to catch accidental wire-format drift in reviewable text form.

Fixture groups:

- `*_payload_envelope.hex`: logical `LedgerPayloadEnvelope` bytes.
- `ledger_commit_store_single_active.cbor.hex`: full `LedgerCommitStore` bytes
  with one active allocation generation.
- `dual_slot_store_valid_newer.cbor.hex`: full dual-slot store where the newer
  generation is valid and authoritative.
- `dual_slot_store_corrupt_newer.cbor.hex`: full dual-slot store where the
  newer generation is corrupt and recovery must use the prior valid generation.
- `stable_cell_record.cbor.hex`: `StableCellLedgerRecord` value bytes stored
  inside the `ic-stable-structures::Cell` envelope.
- `memory_manager_descriptor.cbor.hex`: `MemoryManager` slot descriptor bytes.
