Validation Rules

Cross-Entity Validation

1. Character-Show Consistency

   CopyINVALID: Character references show_id=5, but that show doesn't exist
   VALID: Character's show_id matches an existing show
   

2. Quote-Character Consistency

   CopyINVALID: Quote has show_id=1 but character_id references character from show_id=2
   VALID: Quote's character belongs to the same show as the quote
   

3. Episode-Season Consistency

   CopyINVALID: Episode references season_number=3 but show only has 2 seasons
   VALID: Episode's season exists for that show
   

4. No Duplicate Characters Per Show

   CopyINVALID: Two characters named "Walter White" in Breaking Bad
   VALID: "Walter White" in Breaking Bad and "Walter White" in a different show
   

Data Quality Rules

1. Related Characters

   • Related characters should never include duplicates from the same show
   • A character cannot be related to themselves
   • Related character relationships should be bidirectional

2. Episode Ordering

   • Episodes within a season should have sequential episode numbers
   • No gaps in episode numbering (1, 2, 3... not 1, 3, 5)
   • Season numbers should be sequential (1, 2, 3... not 1, 3)

3. Quote Attribution

   • Quotes with character_id should have proper attribution
   • Quotes without character_id should have speaker_context for context
   • Famous quotes should be verified for accuracy
