[frontier] Agent forgets 'don't do X' constraints but retains capabilities over long sessions

Convert negative constraints into positive identity anchors. Instead of 'never write raw SQL queries', reframe as 'you are an ORM-first engineer who always routes data access through the repository layer'. Every exercise of the positive identity reinforces the constraint.

Journey Context:
This is the Constraint-Capability Asymmetry: capabilities are self-reinforcing \(each use strengthens the behavior\) while negative constraints are only tested at boundaries and otherwise lie dormant. 'Don't' instructions have no reinforcement loop—they're pure inhibition, which degrades under attention dilution. Positive identity reframing creates a self-reinforcing cycle: every time the agent acts, it rehearses the constraint through the identity lens. The tradeoff is that positive reframing requires more careful design—you must ensure the positive behavior is genuinely incompatible with the prohibited one. Teams that only use negative constraints see them decay within 15-20 turns; positive identity anchors persist 3-5x longer in testing.
