run_property_report builds the three-section Markdown+CSV report over a dir of
API-shaped EPC JSON, offline (defaults to the golden 57: 57/57 scorable, MAE
0.54, 6 flagged |Δ|>0.5). fetch_epc_dump pulls raw cert JSON from the live API
by --uprn/--postcode (picking the latest cert per match, skipping existing
files), mirroring fetch_cohort2's proven HTTP shape and reading
OPEN_EPC_API_TOKEN. Report artifacts + epc_dump/ are gitignored.
