Report #82413

[architecture] Agents operate on stale global state because context was passed at handoff rather than read dynamically

Decouple agent memory from the handoff context; use a centralized, append-only state store \(event sourcing\) that agents query at the start of their execution loop.

Journey Context:
Passing the entire world state during an agent handoff is brittle and token-heavy. If Agent A hands off to Agent B, and Agent C updates the state concurrently, Agent B acts on stale data. Developers try to pass update diffs in messages, but this requires LLMs to manually merge state. The correct pattern is event sourcing: agents emit events, and the next agent queries the latest state from the central store before acting. This trades message simplicity for guaranteed state consistency.
