[Timestamp] byte[] doesn't work under SQLite (the test backend) — EF expects the DB to populate it on insert, but SQLite has no equivalent of Postgres's xmin. The WHERE Status = Unclaimed filter plus IInventoryService's viewer-level concurrency is the practical defense; RowVersion was only a backstop. Regenerated the migration without the RowVersion column. Wire reward_type on the gift endpoint uses a gift-specific scheme that diverges from UserGoodsType for currencies: wire 1 = Crystal (enum=2), wire 9 = Rupy (enum=9), wire 4 = Item (enum=4). A naked cast resolves wire 1 to UserGoodsType.RedEther and silently grants the wrong wallet — restored the explicit WireRewardTypeToUserGoodsType map from the old tutorial controller. Retrofits existing GiftControllerTests to call SeedTutorialPresentsAsync on the new helper (RegisterViewer doesn't auto-seed; only the prod signup path does). All 7 existing tests pass.
