## Summary Currently, we use request-time logic to determine the user_instructions and environment_context messages. This means that neither of these values can change over time as conversations go on. We want to add in additional details here, so we're migrating these to save these messages to the rollout file instead. This is simpler for the client, and allows us to append additional environment_context messages to each turn if we want ## Testing - [x] Integration test coverage - [x] Tested locally with a few turns, confirmed model could reference environment context and cached token metrics were reasonably high
