Report #74148

[synthesis] Agent produces final answer that drifts from original goal despite no errors in intermediate steps

Implement 'goal-revalidation checkpoints' after every 2-3 tool calls, explicitly comparing current state against original task constraints using structured diff verification rather than implicit context retention.

Journey Context:
Standard agent frameworks assume local validity implies global satisfaction, but compositional generalization research shows this fails when subtasks interact. Adding more validation of individual tool outputs catches syntax errors but misses semantic drift. Backtracking is computationally expensive; proactive revalidation is cheaper and prevents cascade errors by forcing explicit alignment checks before context becomes too polluted.
