# channel resolution

## Verification Boundary

This suite checks isolated calculations, validation or presentation with process-local inputs. It does not establish a deployed workflow.

## What This Suite Proves

Its cases exercise deliver personal notices in the console; explain unavailable and unsupported routes; queue only eligible delivery-work channels; select only reachable adapter destinations; explain skipped channels consistently.

The registered scenario bindings identify the assertions this executable file contributes. They retain individual test references so that a composite scenario does not become a claim of complete execution by one file.

## What It Does Not Prove

Local outcomes do not prove deployed queues, external provider acceptance, production credentials or complete browser behavior. No fresh execution or conformance result is claimed.

## Real Dependencies and Test Doubles

The test file identifies its pure inputs or presentation doubles. Console component suites use recorded request handlers; pure validation suites require no external provider.

## Must Not Be Doubled

The calculation, validator or component under test must execute its real implementation. Doubles supply inputs and external responses without replacing the behavior being proved.
