Shop-owned activities on one SKU, concrete groups with an
open/successful/expired/cancelled lifecycle, and one paid membership row per
paid order. Checkout accepts a single-SKU quantity-1 intent, snapshots the group
price and identity on the pending order, and opens or references a group; a paid
seat is claimed only at payment, which locks the group and fills it exactly at
capacity.
Pending-payment cancellation restores SKU stock only and never rolls back paid
seats; an unpaid opener cancelling closes a still-empty group. Coupons are
refused on a group shop order, and the flash-sale exclusion is now enforced in
both directions because the activity table exists, which activates the guard
add-flash-sales shipped dormant. The activity column names follow the contract
recorded in this change's design.
Surfaces (shop-admin, mall) and seeding follow.
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.
Sync the shop-coupons 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.
Renaming the coupon scenario in the flash-sales and group-buying order deltas
to the exact name now in the main order spec keeps those changes archivable,
since a MODIFIED requirement replaces the whole block.
Rename the group-buying "Order lifecycle" cancel scenario to the exact name
the current order spec uses; a MODIFIED requirement replaces the whole block,
so the old name made archive refuse to drop the existing scenario.
Replace the placeholder Purpose in the archived address-book spec, which the
wave-7 archive left as TBD and strict validation rejected.
openspec validate --all --strict is green again.
Capture exclusive promotion composition, empty-group cancel, and mall surface scope so the five marketing changes can be implemented without stacking or lifecycle ambiguity.
