[synthesis] Agent wastes excessive steps working around impossible plan steps rather than backtracking to replan

Implement 'feasibility gates'—before executing any plan step that assumes resource existence \(files, records, permissions\), perform a lightweight 'exists' check; if failed, trigger immediate replanning rather than error handling

Journey Context:
Agents often create plans like: 1\) Read file X, 2\) Modify content, 3\) Write back. If file X doesn't exist, the agent doesn't immediately backtrack to 'Create file X' or 'Ask user for file.' Instead, it treats the error as an obstacle to work around: 'File not found, let me search for similar files,' then 'Maybe it's in a different directory,' spending 10 steps searching before concluding it needs to create the file. This happens because agents treat plan steps as commitments rather than hypotheses. The failure mode is 'plan continuation bias'—agents assume the plan is correct and the world is wrong, rather than vice versa. Most implementations catch exceptions but don't trigger plan re-evaluation.
