Report #43174

[frontier] Subtle shifts in agent tone and boundary recognition due to quantization and KV-cache compression in long sessions

Periodically force a full context recomputation \(a 'hard refresh'\) by summarizing the session state and restarting the agent with the summary plus the original system prompt.

Journey Context:
In extremely long sessions, KV-cache optimizations and quantization can lead to 'token loss' where subtle but critical constraint tokens are dropped from active attention. A periodic hard refresh clears the degraded cache, re-establishes the full attention weight of the system prompt, and compresses the history into a high-signal summary, effectively resetting the agent's identity baseline.
