[synthesis] Agent executes outdated plan steps after environment state changes externally

Require an environment state hash or diff-check immediately prior to any write operation. If the state has drifted from the plan's assumed baseline, force a re-planning step.

Journey Context:
Agents generate a multi-step plan at T=0. At T=5, a linter or external process modifies the file. The agent, still following the T=0 plan, applies a patch based on the old file state, causing merge conflicts. The agent then tries to fix the syntax error, spiraling into complex debugging of its own mess. The root cause is treating the plan as a static script rather than a reactive assertion. The fix shifts the agent from execute plan to verify precondition, execute, verify postcondition.
