+### F43 Unit pick-list variant in SQL (found 2026-10-24 during case 4712, from code)
+
+`UnitPickList.GetVariantCriteria` takes a `customerid:<value>` variant from the request and returns
+`aunit.customerid = {v[1]}`, the value unparsed, which `PickListSqlBuilder` adds to the query. The
+route (`pick-list/list`, `pick-list/single`) is open to every login, customer contacts included. Same
+class as F18 and F26. **Correction to pass 6:** "Raw SQL: what was checked and found safe" said the
+pick-list variants were parsed as numbers or matched to fixed strings; that holds for the other six
+lists with variants but not this one (the pass 6 search looked for `{variant}` and `{crit[...]}`
+interpolations and missed `{v[1]}`). Fix: parse the value as a `long` and ignore the variant otherwise,
+as the other lists do.
