@@ -31,15 +31,22 @@ Category assignment (dump -> PG):
   mapped_data.category from a MySQL dump when available.
 
   Dump path (first match wins):
-    1. -mysql-dump flag
-    2. SEED_A1_MYSQL_DUMP
-    3. Auto-detect: ~/Downloads/descrybe_new (1).sql or descrybe_new.sql
+    1. -mysql-dump flag / admin body mysql_dump

+       ~/Downloads/descrybe_new (1).sql or descrybe_new.sql
 
-  One-off without wipe:
+  Git-Syncer / production: copy the dump onto the API host, e.g.
+    <deploy-root>/scripts/seed/descrybe_new.sql
+  or set SEED_A1_MYSQL_DUMP=/absolute/path/descrybe_new.sql in the API env.
+  Then use Admin → Companies → Sync A1 (no CLI DATABASE_URL needed).

+  One-off without wipe (CLI; loads monorepo-root .env when unset):
   go run ./cmd/seed-a1 -mode backfill-categories
 
-  That also deletes Postman Elkotex fixture EANs (5905575903198, 6970995789942)
-  from non-A1 tenants (Platform Demo must not mirror them).
+  Admin Sync A1 = dump category backfill (when dump present) + Fix hygiene
+  (prompts, weak hashes, bidirectional category backfill, attr sanitize).
+  It does NOT wipe/reimport the ~25k catalog.
