[frontier] Agent personality and constraints drift over long multi-turn sessions

Inject identity beacons — condensed restatements of core identity and hard constraints — every 10-15 turns or at task-transition boundaries, not just in the system prompt at session start.

Journey Context:
The original system prompt's influence decays as context grows because transformer attention distributes weight across all tokens, diluting the signal from early instructions. The agent that starts your session is not the same one 50 turns later — not because it was overwritten, but because the attention landscape shifted. Identity beaconing counteracts this by re-anchoring the agent at natural breakpoints \(tool returns, task handoffs, user affirmations\) where a brief constraint restatement feels coherent rather than intrusive. The tradeoff: beacons consume context window space. Teams that try to solve this by making the system prompt longer see no improvement — the problem is attention dilution, not specification inadequacy. The beacon must be a compressed distillation, not a copy-paste of the original prompt.
