[synthesis] Agent loop completes every step but produces the wrong output because it stopped questioning its own plan

Insert an explicit plan-revalidation checkpoint after every external tool call that asks: 'Given this new observation, is the original goal still achievable and is this still the right plan?'

Journey Context:
ReAct literature treats step success as progress, while debugging literature treats silent assumption-drift as the core failure mode. No single source shows the cascade: a plausible first step creates an implicit assumption that gets baked into every later step. The synthesis is that success signals are not plan-validity signals. Replanning every turn is too expensive, so a lightweight revalidation gate at observation boundaries is the right tradeoff.
