Report #72548

[frontier] Agent accumulates 'broken' context where early critical instructions are separated from recent context by irrelevant noise, causing inconsistent behavior

Implement 'Context Window Defragmentation' - every N turns or when entropy is detected, trigger a re-ordering pass that moves high-priority instructions \(\) to the first 1k tokens \(attention sink\), compresses intermediate turns via summarization, and ensures contiguous placement of related constraint sets

Journey Context:
Most developers append messages to the end of context, not realizing that middle positions suffer attention decay and fragmentation. The 'attention sink' phenomenon \(first tokens get disproportionate attention\) is well-documented but rarely exploited. The fix treats the prompt as a physical layout problem, actively managing the spatial arrangement of tokens to optimize attention flow, similar to memory defragmentation in operating systems, ensuring critical instructions remain in high-attention zones.
