Report #75624

[synthesis] Agent silently abandons its initial plan and applies suboptimal patches without throwing an error

Log the initial plan or system prompt goal, and at the final step, use a lightweight local classifier to compare the final state against the initial plan. Alert on plan-action divergence rather than task completion.

Journey Context:
Agents often start with a sound architectural plan but get distracted by a minor lint error or test failure. They pivot to whack-a-mole patching, eventually passing tests but accumulating technical debt. Because the final code passes CI, standard monitoring sees a success. The leading indicator is the semantic distance between the early reasoning steps and the final tool sequence.
