# Boundary Discipline ## Trigger At parsing, framework, process, network, storage, or user-input boundaries. ## Rule Validate and normalize at boundaries, trust internal invariants, and keep business logic free of adapter noise. ## Application 1. Name the concrete decision this principle changes. 2. Apply the rule to that decision, not as a decorative citation. 3. Prefer evidence from the current repository/runtime over generic preference. 4. If the principle conflicts with an explicit user constraint, keep the constraint and state the tradeoff.
