Feature: Building the catalogue from announcements
  Discovery is the read side. It owns no ingestion of its own: it learns what
  exists by subscribing to the catalogue topic cms announces ready videos on,
  and keeps its own copy in its own database. Nothing polls cms and neither
  service reads the other's tables.

  A video therefore reaches the catalogue only once its transcode has finished
  — which is the point, since a catalogue entry nobody can play is no use.

  Background:
    Given the CMS API is available
    And the Discovery API is available

  Scenario: A video the CMS announces appears in the catalogue
    Given I have registered a video that is being transcoded
    When MediaConvert reports that the job reached "COMPLETE"
    Then the catalogue eventually holds that video
    And the catalogue's copy carries its title, playback URL and categories

  # The catalogue is built from announcements, and cms announces only what came
  # out ready. A video part-way through its transcode is therefore genuinely
  # absent rather than merely late, and saying so is the honest answer.
  Scenario: A video that is still being transcoded is not in the catalogue
    Given I have registered a video that is being transcoded
    Then the catalogue does not hold that video
    And the request is rejected with status 404
    And the problem title is "Video Not In The Catalogue"

  # The catalogue topic delivers at-least-once, and a job's outcome can be
  # reported more than once, so the same video can be announced again. The
  # later announcement is the truth: it lands on top of what is already there
  # rather than colliding with it. Announcing it again with no playlist is what
  # makes that visible — a second announcement carrying identical content is
  # indistinguishable from never having arrived.
  Scenario: A video announced again is updated rather than colliding
    Given I have registered a video that is being transcoded
    And MediaConvert reports that the job reached "COMPLETE"
    And the catalogue eventually holds that video
    When MediaConvert reports that the job reached "COMPLETE" without a playlist
    Then the catalogue eventually holds that video with no playback URL
