[frontier] Agent doesn't suddenly violate a constraint—it gradually softens it through hedging, narrowing, and re-interpretation over multiple turns

Monitor agent outputs for 'constraint softening signals': hedging language \('I'll try to...'\), partial compliance \('except when...'\), or re-interpretation \('in most cases...'\). When detected, re-inject the original constraint language verbatim as a system message. Design constraints with explicit anti-softening clauses: 'This constraint has no exceptions. Do not hedge or qualify it.'

Journey Context:
Constraint violation is a cascade, not an event. Step 1: the agent adds hedging \('I'll try to avoid lists'\). Step 2: it narrows the scope \('I won't use lists in the main output, but supporting notes are fine'\). Step 3: it reinterprets the constraint as a preference \('lists are discouraged'\). Step 4: the constraint is effectively gone. Each softening shifts the model's internal representation, making the next softening more likely—a positive feedback loop toward default behavior. Catching and correcting at step 1 is 10x easier than at step 3. The anti-softening clause works because it gives the model a meta-rule that makes hedging itself a violation, creating a second-order constraint that is more resistant to decay.
