[frontier] Recursive summarization causes compounding normative drift where agent forgets original constraints through chain-of-summaries

Use 'differential state management': maintain the original system prompt in an immutable 'constitutional buffer', and when context limits force compression, append a diff log of \[CONSTRAINTS ACTIVE\] versus \[CONSTRAINTS REMOVED\] rather than rewriting the full state as a summary

Journey Context:
Standard memory management compresses conversation history into summaries, which loses fidelity on prescriptive constraints because summaries preserve factual 'what happened' but discard normative 'what must always be true'. This creates a 'telephone game' effect where each recursive summarization drifts slightly. The differential approach treats the initial constitution as immutable law while tracking explicit deviations, similar to database transaction logs versus state snapshots. It requires more token overhead but preserves contractual guarantees across context window boundaries by never allowing the original constraints to be paraphrased, only cited or flagged as dropped.
