# Importer — Series Arc Extraction

You are a senior story editor reverse-engineering an existing finished work into the **series-level story arc** that PortOS's pipeline persists as `series.arc` + `series.seasons[]`. The source is complete — you are not pitching new directions, you are describing the spine that's already in the text.

## Source context

- **Series name:** {{seriesName}}
- **Content type:** {{contentType}}

## Story shape (Vonnegut)

Pick the single Vonnegut fortune curve that best describes the protagonist's trajectory across the whole work. Allowed ids (return exactly one in the `shape` field):

- **`rags-to-riches`** — sustained rise. Protagonist starts low, ends high, climb is monotonic with a small dip near the climax.
- **`tragedy`** — sustained fall. Starts high, ends low. The reverse curve.
- **`man-in-hole`** — fall then rise. Things get bad in the middle, but the protagonist climbs back out — ends roughly even with or above the start. Most genre fiction lives here.
- **`icarus`** — rise then fall. Triumph followed by collapse. Ends low.
- **`cinderella`** — rise, fall, rise. Two peaks separated by a midpoint crash.
- **`oedipus`** — fall, rise, fall. The protagonist hauls themselves up only to be undone again.
- **`boy-meets-girl`** — relationship-arc variant: meet, lose, reunite. Three beats.
- **`creation-story`** — slow rising arc from nothing toward order or birth. Often ensemble; less personal than rags-to-riches.

Be specific: do not default to `man-in-hole` because it's the most common. If the ending is decisively down, that's `tragedy` or `icarus`; if it's a fall-then-rise but the rise is partial, it's still `man-in-hole`.

## Per-content-type guidance

{{#isShortStory}}
Short stories almost always trace a single shape with one major turn. The whole story fits in one issue — your `seasons` array should typically be a single entry (`number: 1`) covering the entire piece, unless the story has explicit part breaks.
{{/isShortStory}}
{{#isNovel}}
Novels typically divide into 2–4 acts or volumes. Use part / book breaks if the source has them ("Book One", "Part II"). Otherwise look for the major turning points where the protagonist's fortune pivots — those are season boundaries. 2–4 seasons is the usual range.
{{/isNovel}}
{{#isScreenplay}}
Screenplays are single-episode by default — typically one season with one episode. If the screenplay carries explicit act-break headers (`ACT ONE`, `ACT TWO`, `ACT THREE`) and feels like multiple-episode material, you may split into multiple seasons; otherwise keep it as one.
{{/isScreenplay}}
{{#isComicScript}}
Comic scripts mark issues / volumes explicitly with `ISSUE N` or `VOLUME N` headers. If the source uses those, mirror them as seasons (one season per volume). If unmarked, assume ~22 script pages per issue and group into ~6-issue volumes — but only use that as a fallback when explicit headers are missing.

## How to shape the arc

1. **`logline`** — one sentence pitching the WHOLE arc (not the opening). What is this series about, in 25 words or fewer?
2. **`summary`** — ~300–500 words. The act structure across the whole work: where the protagonist starts, the major turns, where they land. Specific enough that someone planning a sequel could tell whether their idea fits the existing arc.
3. **`themes`** — 2–5 short tags. The recurring concerns — `betrayal`, `legacy`, `the cost of memory`, `class & inheritance`. Keep each tag short (≤80 chars). These should be derivable from the text, not aspirational.
4. **`protagonistArc`** — 1–2 paragraphs. Character growth across the whole work: starting moral/emotional state → ending state, and the pivot that drove the change.
5. **`shape`** — one of the eight Vonnegut shape ids listed above.
6. **`seasons`** — break the work into 1–5 seasons. For each:
   - **`number`** — 1-indexed, contiguous.
   - **`title`** — short noun phrase. Use the source's part/volume/act titles verbatim if present, else distill a 2–5 word title from the season's content.
   - **`logline`** — one sentence; what changes in this season.
   - **`synopsis`** — 1–2 paragraphs covering this season's major beats.
   - **`endingHook`** — the image or line that pulls the audience into the next season. Empty string for the final season.
