Shop-owned timed sessions carry SKU activity items with their own reserved inventory and per-customer limit. Checkout resolves eligibility on the server, locks candidate items by primary key after the SKU locks, and splits a cart line into an activity-priced item plus a standard-priced remainder, so every unit price snapshot is honest and a customer cannot exceed the limit. Reserved activity stock and SKU stock decrement together under guards, and a pending-payment cancellation restores both plus any redeemed coupon. Coupons are rejected on a shop order that applied activity pricing, and a SKU cannot join two overlapping enabled sessions. The overlap check against group buying is present but dormant: that capability lands later, so the check activates only once its table exists. Surfaces (shop-admin, mall) and seeding follow.

1. Flash-sale domain and contract
- 1.1 Add additive migrations for shop flash-sale sessions, SKU activity items, reserved stock, per-customer limits, and order-item activity snapshots.
- 1.2 Implement the Rust flash-sale module with shop-scoped session/item management and public active-session discovery.
- 1.3 Add shared flash-sale types, client methods, localized strings, and fixed-data adapter parity.
2. Checkout price and inventory resolution
- 2.1 Resolve active eligible activity items server-side during checkout and snapshot final line pricing and activity identity. Reject coupon selection on any shop order that applied flash pricing; restate coupon persistence for non-flash shop orders.
- 2.2 Conditionally decrement and restore activity inventory with SKU inventory in deterministic lock order; enforce the per-customer limit. Pending-payment cancellation restores both inventories and any redeemed coupon.
- 2.3 Add integration tests for inactive-window fallback, cross-shop configuration rejection, overlapping group-buy SKU rejection, final reserved-stock contention, customer limits, coupon rejection on flash-priced shop orders, coupon restore on cancel, and cancellation restoration.
3. Merchant and mall surfaces
- 3.1 Add shop-admin session and activity-item management and a flash-sale nav entry scoped to the authenticated shop.
- 3.2 Replace the mall flash-sale fixture page with active live sessions, products, price, stock, sell-through, and countdown; show snapshotted activity prices on payment and order-detail views.
- 3.3 Remove affected direct flash-sale fixture imports while retaining fixed-data adapter support.
4. Verification and specification
- 4.1 Seed an active deterministic flash sale and browser-smoke its discovery and checkout pricing path.
- 4.2 Run cargo test for vmall-api, builds for mall and shop-admin, and strict validation for this OpenSpec change.
