Report #15248

[architecture] Multiple agents writing to shared memory causing race conditions and overwrites

Implement an append-only event sourcing model for the shared memory store, where agents emit immutable memory events \(facts/observations\). Use a single aggregator or consolidator process to resolve conflicts and update the read-optimized materialized view.

Journey Context:
When multiple agents share a mutable state \(like a single user profile document\), concurrent writes lead to lost updates \(last-write-wins\). By using event sourcing—where agents only append immutable logs of what they learned—you guarantee no data is lost. A separate process reads the event stream and merges it into the materialized state. The tradeoff is architectural complexity \(managing an event stream and a materialized view\) and eventual consistency, but it guarantees data integrity in concurrent environments.
