Report #59542

[frontier] High-priority constraints \(safety, format rules\) are progressively ignored while low-priority stylistic instructions persist over long conversations

Tag instruction tiers using XML hierarchy markers \(, , \) and implement a validator that re-injects constraints every 5 turns regardless of context window state

Journey Context:
Standard practice treats all instructions as equal text, causing semantic drift where critical rules get buried. The tiered approach recognizes different decay rates. This requires explicit prompt structure parsing, not just appending text, to ensure critical constraints bypass recency bias through programmatic re-injection outside the natural attention mechanism.
