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.

## ADDED Requirements
|
|
|
|
### Requirement: Shop flash-sale configuration
|
|
Shop users SHALL manage only their own timed flash-sale sessions and SKU activity items. An item SHALL have a fixed minor-unit sale price, currency, reserved stock, per-customer limit, and belong to an active SKU owned by the session shop. The service SHALL reject a SKU that already has an overlapping active group-buying activity.
|
|
|
|
#### Scenario: cross-shop SKU rejected
|
|
- **WHEN** a merchant adds another shop's SKU to a flash-sale session
|
|
- **THEN** the API rejects it without creating an activity item
|
|
|
|
#### Scenario: overlapping group-buy SKU rejected
|
|
- **WHEN** a merchant adds a SKU that already has an overlapping active group-buying activity
|
|
- **THEN** the API rejects it without creating an activity item
|
|
|
|
### Requirement: Public active flash-sale discovery
|
|
Customers SHALL list active sessions and their eligible products with current sale price, remaining activity stock, and sell-through information. Inactive, disabled, or elapsed items SHALL not be purchasable as flash-sale items.
|
|
|
|
#### Scenario: window closes
|
|
- **WHEN** a session end time has passed
|
|
- **THEN** it is absent from active discovery and checkout applies the normal SKU price
|
|
|
|
### Requirement: Flash-sale purchase limit and inventory
|
|
Checkout SHALL enforce the activity's remaining stock and each customer's purchase limit atomically with normal SKU stock. A successful order SHALL retain the applied activity item and final price snapshot.
|
|
|
|
#### Scenario: quantity exceeds limit
|
|
- **WHEN** a customer checks out a flash-sale SKU above the remaining per-customer allowance
|
|
- **THEN** only eligible activity quantity receives the activity price and any other quantity follows normal availability and price |
