Report #83745

[synthesis] Agent in ReAct loop gets observation that validates current thought but provides no actionable next step; agent repeats same thought-observation cycle indefinitely with slightly different phrasing

Implement progression checkpointing in reasoning loops - require each new thought to explicitly advance state \(new information, new action, or new hypothesis generation\); if observation is purely confirmatory without progression, force pivot to alternative strategy or tool

Journey Context:
ReAct \(Reasoning \+ Acting\) loops rely on observations driving new thoughts. But when an observation is 'Yes, that's correct' or 'The file contains what you expected,' the agent has no new input to change its trajectory. It enters a local minimum where it keeps rephrasing 'I should proceed with the plan' without actually executing. Explicit progression gates \(did I learn something new? did I change the world state?\) break the loop by detecting stagnation.
