Implement the core logic that transforms raw PokeDB encounter records into our internal format.
|
|
|
|
## Checklist
|
|
|
|
- [x] **Filter by game version**: Given a target game slug, select only encounters where `version_identifiers` includes that game
|
|
- [x] **Parse level strings**: Convert "2 - 4" → min_level=2, max_level=4; "67" → min_level=67, max_level=67
|
|
- [x] **Handle rate variants per generation**:
|
|
- Gen 1/3/6: use `rate_overall` directly as `encounter_rate`
|
|
- Gen 2/4: `rate_morning`, `rate_day`, `rate_night` — flatten to max or average for `encounter_rate`
|
|
- Gen 5: `rate_spring` through `rate_winter` — flatten similarly
|
|
- Gen 8 Sw/Sh: `weather_*_rate` fields — flatten to max
|
|
- Gen 8 Legends Arceus: `during_*` / `while_*` booleans — convert to a presence-based rate
|
|
- Gen 9 Sc/Vi: `probability_*` fields (spawn weights, not percentages) — normalize to percentages
|
|
- Preserve raw variant data in a way that nuzlocke-tracker-oqfo can use later
|
|
- [x] **Aggregate encounters**: Group by (pokemon, method, location_area) and merge level ranges / rates where appropriate (same logic as the Go tool's aggregation)
|
|
- [x] **Group by location area**: Collect all encounters for a location area into a route structure
|
|
- [x] **Handle parent/child routes**: Multi-area locations (e.g. Safari Zone) should produce parent routes with children, matching the existing hierarchical format
|
|
|
|
## Notes
|
|
- Rate parsing needs to handle percentage strings like "40%" as well as bare numbers
|
|
- The Go tool aggregates encounters with the same pokemon+method at a location into a single entry with merged level ranges — replicate this |
