[frontier] Agent retains capabilities but drops safety constraints in long sessions

Deploy 'Dual-Key Prompting': separate capabilities \(positive instructions\) from constraints \(negative instructions\). Tag constraints with a high-privilege marker \(per the Instruction Hierarchy\) and re-inject them via a 'system reminder' every 15 turns, while capabilities remain static in the initial prompt only.

Journey Context:
Research shows LLMs exhibit asymmetric decay: positive instructions \(capabilities\) are reinforced by execution feedback loops, while negative constraints \(safety rules\) are latent suppression rules that decay without activation. Standard prompting treats both equally, leading to 'Constraint Decay' where negative rules are forgotten while positive skills remain. Simple repetition of the entire prompt is token-expensive and prone to saturation. The Dual-Key approach recognizes the different half-lives of these instruction types: capabilities are stable \(set once\), constraints are volatile \(require refresh\). By explicitly tagging constraints as high-privilege and scheduling their re-injection, we match the maintenance schedule to the decay rate, preventing the asymmetric drift that causes safe agents to become capable but unsafe.
