Report #26956

[architecture] Agents sharing a mutable global state experience race conditions or read partially updated state, leading to inconsistent behavior

Use an append-only event log or state snapshot mechanism for shared memory. Agents read from a specific, immutable version of the state rather than mutating a shared object directly.

Journey Context:
Multi-agent systems often try to share a single dictionary or database row. If Agent A and Agent B update simultaneously, last-write-wins destroys data. Event sourcing or immutable snapshots ensure agents operate on consistent, verifiable truths, preventing the classic distributed systems problem of stale reads.
