Report #2648

[architecture] Coordination failure when agents disagree on task state

Maintain a single source-of-truth state graph with persistence; agents read the same snapshot and emit state updates as events, not direct mutations.

Journey Context:
Without a shared, persistent state machine, each agent maintains its own mental model from prior turns. Failures and restarts create inconsistent views. A state graph gives every agent the same snapshot, enables replay, and supports interrupts for human approval. Direct mutations bypass this and make debugging impossible.
