[frontier] Absolute prohibitions \('never do X'\) weaken faster than affirmative duties in long contexts

Convert all negative constraints into positive duty cycles with explicit validation gates \(e.g., 'Always scan before commit'\)

Journey Context:
Negative instructions \('never', 'don't', 'avoid'\) suffer from 'Polarity Decay' in attention mechanisms. Maintaining an active negation across many turns requires higher attentional energy than maintaining a positive duty, because negation requires verifying absence while affirmation requires verifying presence. Over long contexts, the scope of negation narrows or the polarity flips \('never do X' becomes 'do X rarely' becomes 'do X'\). This asymmetry is documented in prompt engineering guides where negative instructions are explicitly flagged as less reliable than positive ones. Production teams in 2026 systematically eliminate negative constraints, converting them into 'Positive Duty Cycles' - required steps in a process. Instead of 'Never commit secrets', the duty cycle is 'Always run secret-scan before commit'. This leverages the model's stronger retention of procedural sequences over prohibitions and aligns with the Instruction Hierarchy research showing that constraints must be formulated as superordinate positive duties to survive context window pressure.
