Flash-sale spikes, multi-channel sync lag, and bundle math oversell real inventory every day — and every oversold order becomes a refund, an apology, and a support ticket. Inventory Guard checks true availability at checkout and holds the order before the promise is made.
Two hundred checkouts race for eighty units. The gate counts down real availability per order instead of finding out tomorrow.
Sold out on Shopify, still live on the marketplace. Orders against stale stock are held until the numbers agree.

Availability can't be confirmed (sync gap, missing count) — flagged for a person instead of guessed.
