 ## Near-Term D&D Pipeline
 
-### Location Extraction
-
-- Add a D&D artifact for locations visited by the party or otherwise mentioned
-  in the transcript.
-- Distinguish observed visits from references, plans, recalled places, and
-  uncertain or inferred locations so a mention alone is not reported as a
-  visit.
-- Preserve transcript evidence for each visit or mention and reconcile aliases,
-  nested places, and repeated appearances without collapsing distinct
-  locations that share a generic name.
-- Define how the location artifact should ground later narrative reports and
-  whether future event artifacts should retain canonical location identities.
