# Replayable timeline

The full sequence of observations can be replayed to reconstruct state at any timestamp. This enables deterministic debugging and incident analysis.

## Before vs after

Before: after an incident, you only have current snapshots and partial logs. After: replay from observations reproduces the exact state transition path that led to failure.

\# List timeline events
neotoma timeline list

# Get one event and inspect linked entities
neotoma timeline get <event\_id>
neotoma relationships list --entity-id <entity\_id>

Replay depends on [deterministic state evolution](/deterministic-state-evolution) and supports [reproducible state reconstruction](/reproducible-state-reconstruction). See [auditable change log](/auditable-change-log) for provenance.
