Event Sourcing
A software architectural pattern that persists system state by recording all state changes as an immutable sequence of events. The current system state can be reconstructed at any point by replaying this event sequence, providing strong factual constraints and a complete history of state transitions.

Event Sourcing is an architectural pattern that models system state as an immutable sequence of events, persisting the fact of every state change, with the current state derived by replaying all historical events in order; its advantages include a complete audit log, the ability to rebuild the state at any point in time, and the ability to fix projections or add new read models through replay, while the cost is that querying the current state requires aggregating events, and it is usually combined with CQRS and materialized views to optimize read performance.
The core persistence pattern is: write one JSONL audit record per state transition, and read the tail of the log on each restart.
The decision graph uses an append-only model, with one line per decision; overturning a decision adds a new line, and history is never rewritten.
Append-only session history and forking are distributed systems design patterns borrowed from Event Sourcing architecture, allowing resumption from a validated checkpoint without replaying the entire session.
Persistent workflows typically rely on Event Sourcing or Checkpointing mechanisms.
A database's Write-Ahead Log (WAL) or Event Sourcing records committed and persisted state changes, carrying stronger factual authority than AI Agent traces.
The Write-Ahead Logging (WAL) concept is widely applied in database crash recovery (e.g., PostgreSQL's WAL), distributed consensus protocols (e.g., Raft's log replication), and Event Sourcing architectures.
