Store "not available" root cause reversed from CardsDLL:
- ut/v2/game/fifa17/store is an ELIGIBILITY gate (FutStorePackQuantities
deser 0x1801758c0), not a quantity list. It reads one key "result"
(atom 0x288); the store screen refuses to open unless SUCCESS. Was
unhandled -> catch-all {} -> "not available". Now returns {"result":"SUCCESS"}.
- Store-screen entitlement checks (0x18001749d/0x1800175a2) read IS_*/
*_PURCHASE_ENABLED Blaze flags, separate from storeEnabled. Added the full
confirmed set (14 flags) to FUT_RS4_CONFIG.
- Catalog: assetId (0x23) is the real pack identity; extPrice inner keys are
amount/currency (not mtx). (Also gated client-side by GetSystemMetrics>1024x768.)
Full FUT API reversed (clean-room, CardsDLL only) into docs/ENDPOINT_MAP.md:
~100 FutXServerResponse types across 7 feature groups (market, SBC, draft,
seasons/match, club, store, user/hub), each with deserializer VA, atom-mapped
field schema + types, freeze-risk flags, and minimal known-good JSON.
Tooling kept: tools/atomdump.py (dumps the 907-atom key table at 0x1802d2760)
-> docs/fut_atoms.tsv. Research prompt: docs/OPENCODE_ENDPOINT_PROMPT.md.
