Replay

Replay reconstructs runtime state from emitted events.

Run a protocol:

culsma run path/to/protocol.culs --artifacts-dir tmp/run

Replay the saved result:

culsma replay --run-json tmp/run/run.json --out tmp/replayed_state.json

Replay reads the emitted run.json artifact and writes reconstructed state:

Field	Value
input	tmp/run/run.json
output	tmp/replayed_state.json

Replay supports auditability: the event stream is not just a log for humans, but an input that can reconstruct execution state.
