+## [0.17.4] - 2026-09-15
+
+### Added
+- `boboko:catalog:backfill-skus` — one-off Artisan command to generate a SKU
+  (`SKU-P{product_id}-V{variant_id}`) for every `Lunar\Models\ProductVariant` left with a `null`
+  SKU by the earlier Shopify import (the source export's `Variant SKU` column was genuinely blank
+  for these rows, not an importer mapping bug — see `Modules\MigrateImport\Shopify\
+  ShopifyExportImporter`). Only touches variants missing a SKU; `--dry-run` lists what would
+  change without writing.
+
