Report #98609

[frontier] Agents forget 'never do X' constraints while still following 'always do Y' instructions

Classify constraints as omission \(suppressive\) versus commission \(additive\). Re-inject omission constraints before the model's Safe Turn Depth; monitor omission compliance separately from audit-trail commission signals.

Journey Context:
Gamage et al. show that omission constraints \(e.g., 'never use bullet points'\) decay from 73% to 33% by turn 16, while commission constraints \(e.g., 'include STATUS:'\) hold at 100%. This is Security-Recall Divergence. The danger is that commission constraints generate visible audit trails that look healthy while suppressive safety rules have silently failed. Teams often monitor the wrong signal. The fix is to treat prohibitions as time-bounded and refresh them before the per-model Safe Turn Depth.
