+// GetTenantByID reads one business.
+//
+// Both master joins are LEFT, and that is the whole fix. They were INNER —
+// `app_category` on `a.categoryid` and `app_location` on `a.applocationid` — so
+// a tenant whose category or city master row is missing did not come back
+// "without a category name", it did not come back AT ALL. The endpoint answered
+// 200 with an all-zero record: tenantid 0, every string empty.
+//
+// Four of two hundred tenants have `categoryid = 0`, which matches no
+// `app_category` row, and a newly onboarded shop is the likeliest to be one of
+// them. The damage was silent and total: the shop-profile screen seeded an
+// empty form over a business that had an address, and the setup walkthrough
+// read every field as blank forever — so its first step could never complete
+// however many times somebody saved it.
+//
+// The same INNER-JOIN-as-a-filter mistake has been fixed twice before in this
+// file's neighbours, in GetStaffs and GetUserById. A master row is context; its
+// absence must never delete the record it decorates.
