funman300 897259c8fb fifa17-recon: the /settings 42-flag gate, and why Seasons never asks
ENDPOINT_MAP said this class reads one key, `configs`, and that was true and
useless. What it missed is what happens after each element closes: the client
feeds the STRING VALUE of `type` back through the atom hasher and switches on
the result, 42 arms wide. A flag is a row, not a key, and the client hashes our
string itself.

Followed it to the end. FUN_18011dc50 is the only writer of the IS_* UI gate
bytes inside FutDataManagerImpl, every line is `byte = (field == 1)`, and the
constructor never touches those bytes. So a flag nobody sends is a gate nobody
opens. friendlySeasonsEnabled and enableDraftMode have never been sent by
anything, which is a mechanism for Seasons refusing while making zero requests
to any of the four servers.

The store is the control that makes this readable: IS_STORE_ENABLED is the same
kind of byte and its screen works, because storeEnabled and friends already
ship through the Blaze config store. That list has no seasons or draft flag.

Ship the gates behind FUT_SETTINGS (off/keep/gates, default gates), and
re-assert the working store flags in the same array on purpose: once a
populated array makes the applier run, it writes EVERY gate byte, so omitting
them could switch off a screen that works today.

maximumTradePileSize=100 rides along as a positive control, because a boolean
that changes nothing cannot distinguish "the flag did not help" from "the array
never reached the consumer".

check_settings_flags.py asserts each shipped name against the atom table AND
the recovered switch, since a misnamed flag is silently inert and looks exactly
like a failed fix. enableSquadBuildingSetsFeature is the reason both checks are
needed: a real atom with no arm here.

Live: 439 contract checks pass, market unit suite passes.
Not yet tested in game.

"""Recover the settings-struct DEFAULTS.
Every IS_* gate key is read off one object via vtable accessors:
+0x270 IS_TRADING_ENABLED +0x280 IS_STORE_ENABLED (CONTROL: screen works today)
+0x2b0 IS_FRIENDLY_SEASON_ENABLED +0x2c8 IS_DRAFT_MODE_ENABLED
The server has always sent {"configs":[]}, so whatever those return today IS the
constructor default. IS_STORE_ENABLED's screen works, so its default is true;
the question is whether Seasons and Draft share that or default false.
Route: resolve the object -> its vtable -> decompile the four accessors to learn
which field each reads -> find the constructor and read the initialisers.
