[synthesis] Stale plan execution causing agents to operate on invalid world-state assumptions

Implement "plan validation gates" that re-verify preconditions against current world state before each action, treating plans as speculative hypotheses requiring re-validation rather than immutable scripts

Journey Context:
Agents often generate complete plans at step 1 \(e.g., "read file A, edit line 10, write to B"\), but long-running agents face changing environments—files modified by external processes, network state changes, or side effects from earlier tool calls. The agent follows the stale plan literally, leading to "edit file that no longer exists" or "operate on wrong version" errors. Database systems solve this with Multi-Version Concurrency Control \(MVCC\) and snapshot isolation. Agents need similar semantics: before each action, verify the world state matches the plan's assumptions \(snapshot isolation\), or trigger replanning.
