Feature: Paste a YouTube URL to summarize any video
  As a user
  I want to paste a YouTube link and get a summary
  So that I can pull the specific video I want now, even from channels I don't follow

  Scenario: Paste a valid YouTube URL
    Given I am connected
    When I paste a valid YouTube video URL
    Then the video is added to my feed scoped to me
    And it is queued for summarization through the shared rate gate

  Scenario: Pasting an invalid link is rejected
    When I paste something that is not a YouTube video URL
    Then I get a clear error and nothing is added

  Scenario: Pasting a video that cannot be found is honest
    When I paste a URL whose video cannot be found
    Then I am told it couldn't be found and nothing is added

  Scenario: Pasting the same video twice does not duplicate it
    Given I have pasted a video
    When I paste the same video again
    Then my feed still has exactly one entry for it

  @pending
  # Covered by the engine's ADR-010 no-transcript terminal state (degrade-never-error);
  # there is no paste-specific test for it.
  Scenario: A pasted video with no captions resolves honestly
    When I paste a video that has no captions
    Then it resolves to the "no transcript available" terminal state
