CL-WA-LAB-LINK

Washington: the master already holds 203,058 cannlytics_expand WA rows (63,523 distinct lab_id like LR.PF.4166701011.002, 42,146 with THC), and the full staging file holds 202,812 WA samples keyed by a numeric sample_id with external_identifier 4166701011 in the raw payload. No exact shared id, so the 166,405 WA samples with stated-percent potency were **held** (lab_sample_link.how = held_duplicate_risk), not added. Approve linking by external_identifier = the middle segment of lab_id (exact, but a parse), then enrich or add?
