"""End-to-end tests for `harlo intake`.

Runs the intake CLI through Click's CliRunner with stdin scripted,
asserts that:
  - status reports no in-progress intake on a clean tmp tree.
  - start completes with a 6-question scripted answer set.
  - The completed payload validates against intake_form_schema.json.
  - Three INTAKE_CALIBRATED layers are emitted.
  - The in-progress temp file is cleaned up on completion.
  - cancel discards the in-progress temp file.
