Report #74568

[architecture] Agents operating on stale shared state because updates are pushed asynchronously without receipts

Use a centralized, append-only state graph where agents must pull the latest state before acting and push atomic diffs, rather than maintaining independent local state copies.

Journey Context:
Passing state via messages inevitably leads to divergence. If Agent A and B both read X=1, then A writes X=2, B still thinks X=1 and writes X=3, destroying A's update. Centralized state with atomic updates prevents this. The tradeoff is that the central state store becomes a bottleneck and single point of failure, but consistency is guaranteed.
