[frontier] Agent remembers coding capabilities but forgets safety constraints or negative prohibitions \('never do X'\)

Apply Asymmetric Decay Management: treat prohibitions \('never do X'\) as distinct from capabilities \('you can do Y'\) by encoding them with higher 'thermal mass'—refresh negative constraints at 2x the frequency of capability prompts, use ALL CAPS with higher repetition weight, and store them in a separate 'red list' memory that is immune to standard context compression.

Journey Context:
Empirical observation shows agents suffer 'sign flip' errors—forgetting 'don't' but remembering the action. This mirrors the Waluigi Effect where alignment flips to anti-alignment. In long contexts, positive capabilities \(coding, writing\) are reinforced by successful execution traces, while negative constraints \(safety, formatting\) are only tested when violated. Attention mechanisms naturally weight frequent successful patterns higher. Standard practice treats all instructions homogeneously. The fix recognizes ontological difference between 'can do' \(generative\) and 'must not do' \(restrictive\). Alternatives like rule-classifiers at output layer add latency; this bakes the asymmetry into prompt architecture using techniques similar to classifier-free guidance \(weighted negative prompting\). This is critical for coding agents where 'never use eval\(\)' is more important than 'you can use loops'.
