[frontier] Agent ignores critical safety constraints after 30\+ turns due to context compression

Tag constraints with durability levels \(critical/session/turn\) and prepend a 'hierarchy manifest' every 10 turns that lists only critical constraints with \[IMMUTABLE\] tags, leveraging the model's trained instruction hierarchy to prioritize these over conversational text.

Journey Context:
Teams often try to repeat the full system prompt periodically, but this causes token bloat and actually accelerates drift by training the model to ignore repetitive text. Instead, compressing to only critical constraints with explicit durability metadata leverages the instruction hierarchy pattern where models are trained to respect explicitly tiered commands. This was validated in production by teams observing that agents with hierarchy manifests maintained constraint adherence 4x longer than those with naive re-prompting, specifically because the \[IMMUTABLE\] tag triggers the same attention mechanisms used in safety training.
