Report #7343

[architecture] Multiple agents concurrently writing to the same shared state causing race conditions and overwrites

Implement strict, unambiguous resource ownership per agent, or use reducer patterns/transactional state channels for shared variables.

Journey Context:
Agents acting autonomously often stomp on each other's work if they share global write access. A common mistake is treating shared state as a simple dictionary where the last write wins. The tradeoff is concurrency vs. consistency. Using state reducers \(e.g., appending to a list rather than overwriting a variable\) or strict ownership ensures consistency without requiring distributed locks.
