Report #12661

[architecture] Agents operate on stale context because shared memory updates are asynchronous, leading to contradictory actions

Use an append-only event log \(Event Sourcing\) as the single source of truth for shared state. Agents read the log to reconstruct state before acting, rather than reading mutable shared objects.

Journey Context:
Developers often give agents a shared database row to read/write. If Agent A updates the DB and Agent B reads it milliseconds later, B might get stale data and overwrite A's work. Event sourcing ensures no data is lost and agents can reconstruct exact state. Tradeoff: Higher read overhead to replay events or maintain materialized views, but provides perfect auditability and resolves sync conflicts.
