[synthesis] Agent loses track of state changes in long-running web navigation, interacting with stale DOM elements

Force a DOM snapshot refresh and explicit state re-evaluation after every single action, abandoning the assumption that the page remains static between steps.

Journey Context:
In web automation, an agent clicks a button that triggers a client-side navigation or DOM update. If the agent's next step relies on its internal representation of the page before the click, it will attempt to interact with elements that no longer exist or have changed. This doesn't always throw a hard error; sometimes it clicks the wrong element because the XPath/CSS selector now resolves to a different element. The agent thinks it succeeded because no exception was thrown, but it interacted with the wrong component. Continual forced re-observation \(taking a new screenshot or DOM dump\) is computationally expensive but necessary to prevent silent state drift.
