+Feature: Summarize new videos from subscribed channels
+  As a user who follows more channels than I can watch
+  I want new videos summarized into highlights and takeaways
+  So that I can decide what deserves my full attention without watching everything
+
+  Background:
+    Given I have connected a video account
+    And I am subscribed to the channel "Acme Talks"
+
+  Scenario: A subscribed channel posts a video that has captions
+    When "Acme Talks" posts a new video "Designing for Attention" with captions
+    Then Tapir detects the new video
+    And Tapir resolves a transcript with source "captions"
+    And Tapir produces a summary with highlights and takeaways
+    And the summary is delivered to my store
+
+  Scenario: A subscribed channel posts a video with no usable transcript
+    When "Acme Talks" posts a new video "Silent Montage" with no captions
+    Then Tapir detects the new video
+    And Tapir resolves no transcript
+    And Tapir records the video as skipped with reason "no transcript"
+    And no summary is produced
+
+  Scenario: A channel I am not subscribed to posts a video
+    Given I am not subscribed to the channel "Random Co"
+    When "Random Co" posts a new video "Unrelated"
+    Then Tapir does not process the video
+
+  Scenario: The same video is not summarized twice
+    Given "Acme Talks" posted a video "Designing for Attention" that was already summarized
+    When the watcher sees "Designing for Attention" again
+    Then Tapir does not produce a second summary for it
+
+  # Captions-first is the core path (ADR-007). Audio-download + speech-to-text is
+  # deferred and intentionally has no scenario here yet.
