The committed gate needs frozen, reproducible data without dumping real UK addresses into the repo. Add: - harness anonymise_payload + stable_hash: hash street address + cert number into opaque, dedup-stable tokens; blank secondary address lines + post_town; keep postcode + all component/lodged fields (gov data is OGL). Unit-tested. - scripts/build_epc_prediction_fixture.py: curate qualifying postcodes (>=1 SAP 10.2 target + >=2 distinct addresses) from the local scratch corpus, anonymise, freeze under tests/fixtures/epc_prediction/. - The frozen fixture: 15 postcodes / 280 certs / 36 SAP-10.2 targets. Verified no plaintext address_line_1 and post_town all blank. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
