Function source

This is read live from inventory/derived.py via inspect.getsource(); what you see is exactly what runs.

def compute_size_inclusion(row):
    """True if this landslide meets the inventory's size threshold.

    Thresholds (in m², applied to the role-summed polygon areas):
      - Slow:         area_body   ≥ 50,000  m²
      - Catastrophic: area_source ≥ 50,000  m²  OR
                      area_deposit ≥ 500,000 m²
      - Other types:  None (under-review / unclassified)

    Depends on `area_body` / `area_source` / `area_deposit` being populated
    (apply the area rules first; they in turn depend on polygon_area).

Proposed changes

All rows already match this rule — nothing to apply.
