"""DIMENSION 4 (duplicates), pass 7: the ONE flow that branches on the duplicate
flag, and the request it does or does not emit.

FOUND IN PASS 6: FUN_18009bc40 looks up an item by resourceId in the manager's
vt[0x160] container, reads item+0x10 (duplicateItemId) into a bool, and then:
    duplicate     -> UI command "GotoNewItems", NO server call
    not duplicate -> builds a 1-element FUT Vector of 0x20-byte records
                     {itemId, 7, 0, 0} and calls manager vt[0xc0] with the
                     callback FUN_18009bec0
This is the only branch on the flag in the whole binary (pass 6 was exhaustive
over 13308 functions with controls passing).

THIS PASS: name the actors.
  1. the concrete manager class: who calls FUN_18011d780 (the setter for the
     singleton pointer DAT_1802e6398) and with what object -> its vtable ->
     slots 0xc0, 0x160, 0x7d8, 0xa08.
  2. FUN_18009bec0 (the completion callback), FUN_18009c360 (the owner of the
     function pointer), FUN_18009b480 (the loan-player message builder that
     sits next to it in .text).
  3. what 7 means in the 0x20-byte record.

CONTROL for the vtable: print raw qwords and require slot 0 and 8 to resolve to
real functions before believing any slot; also print slot 0x160 and check it
looks like a small getter (the CreatePack deser calls it and then uses the
result+0x30 as a vector).
