# Product lock input mapping

## Verification Boundary

The assertions call deterministic mapping and rule functions with supplied inputs. No live persistence or HTTP boundary is exercised.

## What This Suite Proves

Mapper assertions distinguish absent, empty and supplied protection values in create and replacement bodies.

## What It Does Not Prove

These assertions do not prove workspace enforcement, transactional rollback, concurrent writes or deployed behavior.

## Real Dependencies and Test Doubles

The functions under test are real JavaScript or compiled service code. Inputs and surrounding contexts are fixtures; PostgreSQL and external applications are absent.

## Must Not Be Doubled

Keep the function under test and its actual return or refusal behavior real. Do not treat a fixture assertion as database, permission or lifecycle proof.
