lamina-product-behavior

Define authoritative runtime product truth across actors and views. Use when modeling domain behavior, setting product density, specifying side effects, protecting invariants, choosing consistency guarantees, handling retries or concurrent actions, defining time semantics and prerequisites, drawing ownership boundaries, or keeping views coherent. Use lamina-systems for causal loops and change over time, and lamina-ux for interaction expression.

# Lamina Product Behavior

## Reference-loading protocol

1. Match the request's primary runtime-truth decision to one row below.
2. Open that linked reference before answering. Add another only when a second
   decision materially changes the answer; do not preload the directory.
3. Start the response with `Using lamina-product-behavior: <topic path(s)>` so
   the selected behavior lens is auditable.
