Frontier of Understanding (NCTs)
by Coowoolf
Before setting outcome goals, identify your understanding level. If you don't know the levers, set a learning goal, not a revenue goal. Don't commit to outcomes you can't control.

error-handling
by 101mare
Patterns for exception handling across application layers: mapping, retry, severity, logging. Does NOT handle: exception hierarchies (use exception-builder), circuit breakers (use resilience-patterns), API errors (use api-design), logging config (use logging-builder). Use when designing error strategies, implementing retry logic, or mapping exceptions between layers. Recognizes: "error-handling", "exception handling", "retry pattern", "error strategy", "exception mapping", "error boundaries", "backoff pattern", "error propagation"
