Report #46838

[frontier] Full system prompt gets lost in long context but partial retention creates dangerous partial alignment

Maintain a 200-token Shadow System Prompt \(compressed constitutional essence\) using LLMLingua-style prompt compression; re-inject this essence every 10 turns regardless of whether the full system prompt is still present in the context window

Journey Context:
Full prompts consume tokens and degrade at different rates than capabilities; sliding windows lose the beginning; the shadow prompt preserves the identity kernel \(safety constraints, output format, persona\) without the full verbosity; inspired by LLMLingua compression but applied specifically to identity preservation rather than cost reduction; proven to maintain alignment in 50\+ turn sessions where standard prompting fails
