purchase_items: generic atomic debit + mint of several items (fail-closed) for
open-on-buy Store packs (Store BUY returns items immediately) + POST
/economy/purchase-items route. Import: add optional entitlements[] to
ProfileImportRequest, seeding unconsumed packs rows in the same transaction (so a
source's unopened packs become Core entitlements); idempotency via the existing
import fingerprint. Tests: 2 purchase_items unit + endpoint + entitlement-seed
import. Core matrix 45 lib + 116 integration + 9 import green; clippy clean.
Add generic /economy/* routes (balance, entitlements, purchase-entitlement,
redeem-entitlement, sell-item, grant-reward, purchase-item) resolving the club
server-side via the same game-scoped active-profile mechanism as /collection —
callers never supply a club id, so there is no cross-club access. Add
list_unopened_entitlements + Entitlement for the reader side. Game-neutral: no
currency names or wire semantics. 4 endpoint integration tests (balance+reward,
purchase+redeem, purchase-item+sell fail-closed, insufficient-funds fail-closed);
full matrix 43 lib + 115 integration green.
