Reverse-engineered the exact FIFA17 store/purchase/credits response
shapes (wf a245577b + wf_76fcf89b) and applied them:
- Store catalog: root key MUST be "purchase" (atom 608) not
"purchaseGroups"; packs keyed by "id" (int16) not packId; price is a
"currencies":[{name,funds,finalFunds}] array; name is "description".
Our old {purchaseGroups:...} hashed to unknown atoms -> empty -> "store
not available". Now the store displays.
- Pack buy: gate open_pack on a transaction with "packId" and state !=
TRANSACTIONCANCEL (the TRANSACTIONCREATED create step) -- fixes the
phantom-buy. Reveal response = {"createPackResponse":{itemList,
numberItems,purchasedPackId,duplicateItemIdList}}
(FutCreatePackServerResponse).
- Coins: /user/credits must return currencies[name=="coins"].funds, not
{"credits":N} (the hub/store read currencies). squad_route also
reconstructs the active squad from club item-id references.
Verified via curl: store shows 3 packs; cancel spends nothing; Bronze
buy awards 5 real players and deducts 400 coins. NOTE: the FUT HUB coin
counter reads from userMassInfo (not /user/credits) -- still blocked on
the userMassInfo-freeze wall (separate reverse in progress).
