funman300 a842c5ffb0 tools(fifa17): answer "who writes item +0x60" — nothing does
The plan called this "the single blocker between 'we can mark a kit equipped'
and 'we can equip a kit'", and recorded that two attempts to find the writer
drowned at 1688 and 4144 instructions.

They drowned because +0x60 is a common struct offset. Two filters make it
readable: only an IMMEDIATE store can introduce a constant (a register store
just propagates one), and item-record code is recognisable by touching +0x4c
(cardtype) or +0x5c (itemState) within a few instructions.

Measured read-only against pid 6580:
  - live +0x60 over all 27 resident records: {1: 23 players, 0: 4 staff}, never 4
  - CardsDLL has 4 comparisons of +0x60 (0, 0, 1, 4); the 4 is the kit gate and
    is the ONLY such comparison in the process
  - CardsDLL has 29 immediate stores to +0x60, constants {-2,0,1,908,0x3f800000}
  - FIFA17.exe, across 79 MB of code: ZERO stores of 4, zero comparisons with 4
  - the gate function has one xref (a jmp) and its address is never taken
  - every register store to +0x60 in CardsDLL is a struct copy or an init

So the gate is not a wire field we failed to send: the value it demands is never
produced by anything. Decoding it fully also shows every OTHER input is already
served — cardtype 7, itemState 101/102, teamid — leaving only the +0xba variant
selector beneath it, which makes a client-side patch the only remaining avenue.
