[synthesis] Agent loop silently stalls after a subtask succeeds but fails to update shared state

Treat every tool output as a state commit: require explicit read-after-write verification before the next planning step; never assume success from a 200 or exit-zero.

Journey Context:
Single sources celebrate tool success, but the cross-source pattern is that agents often call a tool, see a success signal, and proceed without verifying that the actual world state matches intent. The cascade is: success signal -> planner assumes goal advanced -> next action built on stale or missing state -> multiple steps of plausible but wrong behavior. The right call is to force a verify read step, even though it adds latency and token cost; cheaper than recovery. Common wrong moves are retrying the same failing tool or asking the user, both of which hide the verification gap.
