  @shortdoc "Runs ScrypathOps (`scrypath_ops`) tests the same way the scrypath-ops CI job does"

  @moduledoc """
  Runs the `scrypath_ops` application tests the same way the **`scrypath-ops`** GitHub Actions job does.

  Use this from the **repository root** when you change the optional operator Phoenix app under
  **`scrypath_ops/`**, the core library under **`lib/`**, root **`mix.exs`**, **`mix.lock`**, or
  **`scrypath_ops/mix.lock`** (mirroring the path gate described for that CI job in
  [CONTRIBUTING.md](CONTRIBUTING.md)).

  The task runs **`cd scrypath_ops`**, then **`mix deps.get`**, then **`mix test`** with **`CI=true`**.
  The shell script pipes **`printf 'n\\n'`** into **`mix deps.get`** so a workstation TTY cannot block on
  Hex re-auth prompts—the same non-interactive shape as CI.

  Expect Postgres-backed Ecto tests for **`scrypath_ops`**; there is **no** Meilisearch service on this path.

  This task does not accept arguments. For the full CI ↔ **`mix verify.*`** matrix and job names, see
  [CONTRIBUTING.md](CONTRIBUTING.md).
