The A/B identity had owned items but no squad, because the sold-row work only ever
needed the tradePile wire. Every headless check passed -- none of them asks for a
squad -- but the real client refuses to enter the FUT hub with an empty one and shows
a squad update error. A squad is a hub precondition, not a Transfer-List detail.
Seeds via the real PUT /ut/game/fifa17/squad/0, the same request the client sends, so
parse_squad_put/build_squad_write produce exactly what a genuine save would. Writing
Core rows by hand could yield a shape the live path never emits, which is the kind of
divergence that quietly invalidates an experiment.
Picks one owned player per 4-3-3 slot, best rating first, without reusing an instance;
fills the fixed 23-slot array with 0..=10 as the pitch and empty slots as
itemData.id == 0; refuses to write a partial XI and reports any out-of-position
substitution loudly rather than silently reproducing the broken state. Verified
0 -> 11 occupied with no substitutions and a {"id":0} ack.
