  Bindings identify the existing assertions contributing to each scenario; several suites can
  jointly cover a compound scenario.

# Code Template Verification

## Verification Boundary

The suite exercises the isolated rule, calculation or adapter with its supplied fixtures. It does not establish storage or distributed behaviour.

## What This Suite Proves

The code template assertions contribute to the scenarios listed in the register. Each binding retains its exact source test anchor so a reviewer can distinguish an individual contribution from the complete scenario.

## What It Does Not Prove

The register records source inspection only. It establishes no run result, delivery qualification or Product approval.

## Real Dependencies and Test Doubles

The production function under test is real. Its collaborators are supplied as fixtures or replaced ports where the suite declares them.

## Must Not Be Doubled

Keep the production function under test and its refusal or arithmetic result real. Replacing that function with a fixture removes the claimed proof.
