Report #86138

[frontier] Agent exhibits 'Constraint Amnesia' - forgetting negative constraints \(prohibited actions\) while retaining positive capabilities over long sessions

Implement 'Constraint Re-injection Protocol' - every 8,000 tokens or 10 turns, prepend a compressed 'Constraint Manifest' to the active context, listing only prohibitions and guardrails

Journey Context:
Teams often assume system prompts persist indefinitely, but research shows negative instructions suffer attention decay as task-specific tokens dominate the context window. Increasing repetition penalty harms creativity instead. The fix treats constraints as ephemeral state requiring periodic refresh, similar to DHCP lease renewal, matching how transformers actually weight recent tokens.
