+"""Harvest raw EPC certificates into a JSONL corpus for mapper tests.
+
+Source: the bulk EPC dumps in downloads/certificates-YYYY.json. Each line is
+
+    {"certificate_number": "...", "document": "<json string>", ...}
+
+where ``document`` is the cert in the exact shape
+``EpcClientService._fetch_certificate`` returns and
+``EpcPropertyDataMapper.from_api_response`` consumes (it has ``schema_type``,
+``roofs``, ``walls`` ... and matches the committed json_samples).
+
+We want a balanced sample per schema so we can build out and regression-test
+the mappers (notably the incomplete ``RdSapSchema20.0.0``). Schema version
+tracks the dump year, so we read each target schema from a year that's rich in
+it and stop once its cap is full — no need to stream whole multi-GB files.
+
+Year -> dominant schema (see downloads/README.txt):
+    2026 -> RdSAP-Schema-21.0.1
+    2021-2024 -> RdSAP-Schema-20.0.0
+
+SAP-Schema-18.0.0 is a minority schema (~12% of the 2021 dump) but each year
+holds ~1.6M lines, so 2021 still yields well over 1000 — it just scans deeper
+before the cap fills. SAP-Schema-17.1 is richest in the 2019 dump (~20%).
+
+21.0.0 is skipped — it's effectively absent from these dumps.
+
+Run cell by cell. No API token needed — this is pure local streaming.
