  The package test commands include these retained compatibility files; legacy adapters translate inputs
  into the current regional calculation, persistence or local API harness.

  Exact assertion anchors identify the contribution of this file. Scenario-level bindings may compose
  several files; registration does not assert that every file alone executes every scenario step.

# Retained geographic matching compatibility

## Verification Boundary

This retained compatibility suite is included in the current service test commands. Its legacy-shaped inputs pass through adapters to the current regional implementation, so the register counts it as executable regional evidence.

## What This Suite Proves

The linked source assertions contribute checks for text intervals include their endpoints; state matching preserves case sensitivity; country matching supplies the legacy default. A scenario spanning several files relies on those assertions together; this file supplies only its named checks.

## What It Does Not Prove

The register establishes neither a current passing run nor verified conformance. Unbound scenarios, broader feature chains and the delegated infrastructure beyond this execution boundary remain unproved.

## Real Dependencies and Test Doubles

The regional decision functions are real. Legacy unit seams replace settings reads and record writes with test dependencies; these files do not qualify storage or transport.

## Must Not Be Doubled

The calculation, permission declaration or console behavior under assertion must remain the real implementation.
