Report #41102

[frontier] State staleness from observation-action latency in real-time agents

Implement 'Timestamp Locking'—version all observations with high-precision timestamps, reject visual data older than 100ms before action execution, force re-capture if state drift detected

Journey Context:
In high-latency environments, the screenshot taken at T=0 arrives at T=300ms, but by T=350ms when the agent clicks, a loading spinner finished. By tagging every screenshot with nanosecond timestamps and comparing against the system clock before action execution, agents detect when their world model is stale \(>100ms old\) and re-capture the screen, preventing 'clicking on ghosts' of previous UI states.
