The client now issues PUT /squad and the hub renders coins, record and the
squad roster. Three separate root causes, all verified live.
Squad blocker (the long-standing "client never sends PUT /squad"):
AddPlayerToSquad, GetSquads and SelectSquadById issue ZERO network requests
(pure local model reads/mutations, FutSquadServiceImpl vtable 0x180233ff0);
only SaveCurrentSquad writes, and it is unguarded. The client simply needed a
populated ACTIVE squad model, which arrives via the massinfo `squad` member.
No response of ours was ever being rejected.
userMassInfo is NOT required to be {}:
0x180174630 is a FLAT {userInfo, squad, settings, userData} body -- the old
"wrapper key is user" note was wrong, and the historical freeze was the
malformed squad member, not the envelope.
clubNameChangeAllowed must be false:
sending true advertises a club-rename flow whose UI model is never populated;
the client shows a naming prompt and dies confirming it (ACCESS_VIOLATION
reading 0x0 at FIFA17.exe+0x71b8651, 4/4 runs, no CardsDLL frame and no request
in flight). Isolated by a single-variable run; guarded by a contract check.
Endpoint/schema corrections found in live traffic, invisible to static analysis:
* GET ut/%s/squad/list is a real endpoint and must return {"squad":[...]},
not the active-squad object (the /list suffix is appended by the caller, so
it never appeared in the request table)
* PUT lands on ut/%s/squad/<id>, not a bare ut/%s/squad
* userInfo currencies are read as name/funds/finalFunds/active -- there is no
"value" key, so coins always rendered 0
* squad-list elements take STRING formation/squadType, not ints
* the CardsDLL script-API thunk<->name table was off by one (AddPlayerToSquad
is 0x18004aa70; 0x18004aff0 is GetPotentialChemistry_Club)
FUT_MASSINFO / FUT_USERINFO ladders keep every step of the bisect reproducible.
Contract suite 311 -> 358 checks. Tooling added: PyGhidra harness (Ghidra's
Java/OSGi script path is broken on this box), minidump reader, live code grabber.
