This is diagnostic tooling for fiction endings that fail to land. It walks you through six failure states: arbitrary (not set up), predictable (no surprise), unearned (deus ex machina), expanding (raises new questions instead of resolving), overexplained (theme speeches and endless epilogues), and pacing mismatch (rushed or dragging). Each state gets specific checklists and interventions. The core insight is solid: good endings feel both inevitable and surprising, which sounds contradictory but works when you plant seeds early and subvert surface expectations while fulfilling deeper ones. Use this when your climax works but the resolution doesn't, or when beta readers say "that's it?" The diagnostic checklists are genuinely useful for identifying which type of ending problem you have.
