  # The coverage floor the Lens pass enforces (`make verify` -> `make coverage`
  # in app/). Rule: the threshold is a FLOOR. Raise it as behavior-test yaks
  # land; never lower it. A drop means the change (or an exclusion) is wrong,
  # not the floor.
  #
  # Measured 2026-10-26 (PostgreSQL on localhost:5432, exclusions below):
  # 86.17%, identical via `mix test --cover` and via
  # `mix test --cover --export-coverage default` + `mix test.coverage`, and
  # stable across seeds. Floor is the integer below that.
  #
  # `test.coverage` deletes stale exports before sampling: `mix test.coverage`
  # imports *every* .coverdata it finds, so leftover exports from earlier runs
  # pool into the total and quietly inflate it.
  #
  # Excluded are modules the suite cannot or should not exercise; counting them
  # would move the number without saying anything about app behavior:
  #
  #   * framework glue generated by `use`:
  #       Firehose.Repo           `use Ecto.Repo`
  #       Firehose.Mailer         `use Swoosh.Mailer`
  #       FirehoseWeb.Telemetry   Phoenix's telemetry supervisor + metric list
  #       FirehoseWeb.ErrorHTML   Phoenix error renderers, both delegating to
  #       FirehoseWeb.ErrorJSON   Phoenix.Controller.status_message_from_template/1
  #   * FirehoseWeb              the `use FirehoseWeb` macro: imports and aliases
  #                              only, nothing that executes
  #   * Firehose.Release         production release tasks (`mix ecto.migrate` on
  #                              Dokku); the suite never runs them
  #   * Firehose.Checks.NoConnShadowing
  #                              lib_dev credo check, exercised by `mix credo`
  #                              and not by tests
  #   * test scaffolding         Firehose.DataCase, FirehoseWeb.ConnCase,
  #                              Firehose.AccountsFixtures, Firehose.Test.FakeBlog:
  #                              fixtures measure the tests, not the app
  #
  # Everything else counts — CoreComponents, controllers, LiveViews included:
  # that is where the behavior-test work shows up as a higher floor.
