Report #47102

[synthesis] Agent generates actions that made sense in original plan but are now orphaned due to changed context

Require explicit re-grounding before each action: force the agent to re-verify that the current context still matches the preconditions of the planned action; if context has drifted, force replanning rather than continuing with stale plan.

Journey Context:
Agents create elaborate plans \(step 1: read config, step 2: modify config, step 3: restart service\). Between step 1 and 2, the environment changes \(config file is deleted by another process\). The agent proceeds with step 2 based on the stale assumption from step 1. This is 'plan continuation bias' in autonomous agents. The common fix of 'maintain a plan and execute it' assumes static environments. Re-grounding means explicitly checking preconditions before each action, treating the plan as a hypothesis rather than a script. This adds overhead but prevents orphaned actions that execute against ghost states.
