Narrative Shapes
From the Meridians Wiki · Public · Maintained · joint
Shapes classify the macro-structure of delivery curves — how intensity rises and falls across the full story.
| Shape | Description | Curve Pattern |
|---|---|---|
| Climactic | Build, climax, release — one dominant peak defines the arc | Steady rise → sharp peak (mid/late) → decline |
| Episodic | Multiple peaks of similar weight — no single climax dominates | Repeating rises and falls, no clear maximum |
| Rebounding | A meaningful dip followed by strong recovery | Start high → collapse → strong recovery |
| Peaking | Dominant peak early or mid-arc, followed by decline | Early high → sustained fall |
| Escalating | Momentum rises overall — intensity concentrated toward the end | Gradual, sustained rise to finish |
| Flat | Too little structural variation — no meaningful peaks or valleys | Near-constant delivery values |
Detection Metrics:
- Overall Slope — Macro trend (rising, falling, stable)
- Peak Count — Number of detected local maxima
- Peak Dominance — Largest prominence / total prominence
- Peak Position — Where the dominant peak falls (0..1)
- Trough Depth — Magnitude of central valley (V-shape detector)
- Flatness — Standard deviation of smoothed curve
