Sync the flash-sales capability plus the order, frontend-mall, and frontend-shop-admin requirements into the main specs, and write the capability Purpose the archive leaves as a placeholder. Restate the flash-price and coupon-exclusion scenarios in the group-buying order delta, since its MODIFIED checkout block must carry the scenarios the main order spec now has.

Why
The mall's flash-sale page is display-only and prices are fixture-derived. A real event must allocate stock and resolve activity pricing inside checkout, not trust a price shown by the client.
What Changes
- Add shop-managed flash-sale sessions and activity products with localized display data, fixed minor-unit activity price, window, per-customer limit, and isolated activity stock.
- Add public session and product discovery APIs and replace the flash-sale page fixtures with live data.
- Make checkout resolve an active eligible activity server-side, atomically decrement activity stock with SKU stock, and snapshot the applied activity price on the order item.
- Compose exclusively with other promotions: a line MAY receive flash pricing or group-buy pricing, never both; a shop order that applied any flash price SHALL reject a coupon. Restate shop-coupon redemption and pending-payment coupon restore in this change's
orderspec so archival does not drop them. - Add shop-admin session and activity-product management scoped to the authenticated shop; mall payment and order-detail views show the snapshotted activity price.

Non-goals
