Hindsight asks what useful context a reasoning pass can give a separate model before it acts.
An earlier version divides that context into a strategy and a record of relevant facts. The executor receives that information along with the conversation history. When evaluation returns an error, another reasoning pass can revise the context before a retry.
The project has since moved into training and agent-runtime work. The recurring question is how much information to carry forward, how to keep it grounded in the task, and when an additional reasoning step is worth its cost.
Early comparisons were small and exposed regressions as well as improvements. They are useful for directing further experiments, not enough to establish a general advantage.
