`card_identity_probe` reads the PLAYER slots (F_NATION 0x148, F_LEAGUE 0x154). A
manager does not use those, so grading a manager with it reports nation=0 /
leagueId=0 and reads like a server bug when it is only the wrong offsets.
The manager layout, from the Ghidra reversal already recorded in fut_staff.py, is
teamid rec+0x94, nation rec+0xde, leagueId rec+0xe0, talkrating rec+0xe2,
negotiation rec+0xe3. The managercards merge (FUN_1801356c0) NEVER writes +0xde
or +0xe0, which is exactly what makes them a clean test: whatever sits there came
from our JSON and nowhere else.
Read against the live client (pid 6580, 27 records in the CardsDb map):
resource teamid nation league talkrating negot verdict
1000509 241 45 53 0 3 SERVER FIELDS LANDED
So the manager's chemistry fields DO reach the record, and `negotiation=3` agrees
with managercards row 1000509, i.e. the merge ran as well. That moves manager
nation/league from INFERRED to PROVEN without a screenshot.
