Report #59759

[frontier] Critical safety constraints buried in turn 3 are ignored by turn 40 \(Lost in the Middle\)

Apply Floating Thermocline Markers: wrap critical constraints with <\|CRITICAL\_START\|> and <\|CRITICAL\_END\|> tokens and configure the context manager to never compress or summarize content between these markers

Journey Context:
Research shows LLMs suffer 'Lost in the Middle' attention decay where middle context is effectively ignored. Standard context compression \(summarization, sliding windows\) treats all text equally, often dropping safety text. By marking constraints as 'hot layer' content that cannot be summarized, you maintain the thermocline barrier. Alternative: periodic re-injection causes attention fatigue and token bloat.
