Report #37786

[frontier] Instructions located in different 'zones' of the system prompt \(beginning vs end\) decay at different rates due to positional attention bias

Implement 'Rotating Anchor Placement' - critical constraints are temporarily moved to high-salience positions \(beginning and end\) mid-session using dynamic prompt reconstruction

Journey Context:
Cognitive load theory applied to prompt engineering: primacy and recency effects create uneven retention. Static placement leads to 'middle blindness' where central constraints fade. Dynamic rotation keeps critical instructions in high-attention zones without adding length. Must use structured delimiters to enable safe reconstruction.
