[frontier] Positional decay causes early critical instructions to lose effectiveness as conversation grows

Implement prompt rejuvenation: every N turns, rotate position of critical constraints within context window or use attention masking to counteract U-shaped decay curves.

Journey Context:
Research shows middle positions suffer worst attention, but early positions also decay relative to recent tokens. Common fix is appending constraints to the end, but this creates recency bias where final instructions override earlier safety constraints. The right call is periodic rotation or 'refresh' that brings critical constraints back to high-attention zones without making them permanently recent. Tradeoff: requires context manipulation or model-level access, but solves the fundamental positional bias in transformers.
