Report #42508

[frontier] Agent has drifted so far from initial constraints that mid-session correction is impossible; requires full restart and loss of session state

Implement constitutional checkpointing: use a secondary 'auditor' model to compare current agent state against initial constraint hashes every N turns; on divergence >epsilon, trigger 'soft reset'—rewind to last good checkpoint and re-inject constitutional principles without losing session history

Journey Context:
Production teams in 2026 are treating agent sessions like database transactions. The naive approach—hoping the agent self-corrects—fails because drift is monotonic \(entropy only increases\). The breakthrough is separating session history \(the log\) from agent state \(the interpretation\). A secondary evaluator \(smaller, faster model\) computes semantic similarity between current agent outputs and the initial constraint document using embedding distance. If KL divergence exceeds a threshold \(epsilon\), the system performs a 'soft reset': it truncates the context back to the last checkpoint, injects a distilled 'constitutional summary' \(what we agreed on, what constraints remain\), and continues. This mimics git rebase for agent cognition.
