"""Persistent FUT profile store for the FIFA 17 offline backend (OpenFUT).

A single JSON file holds the user's save: coins/points, owned club items, squads,
and record. Loaded once, saved on every mutation. This is the "user + saved files"
layer; packs and the starter grant build on it. (Later this gets ported into
openfut-core's SQLite backend behind a FIFA-17 bridge; JSON keeps iteration fast
while we nail the wire format.)

Item shape mirrors what /club and /squad already serve (fut_seed.player_item):
resourceId/assetId + attrs; identity (name/photo/club/nation) resolves locally in
FIFA from dbdata.dll on the club-search/add path (see docs/CARD_SYSTEM.md).

# ---- FUT_DISCARD_TABLE: the REAL FIFA 17 quick-sell values ------------------
#
# quick_sell() used to pay an invented rating tier (600/300/150/50). That number
# was wrong for every card. The real table is `fcc_discardcoins` in the client's
# own game DB, 141 rows keyed (cardtype, level, rare) -> price, recovered from the
# running client 2026-08-05 and verified against 22 live club items, 22/22 exact.
#
# The client computes the DISPLAYED value itself with the same table whenever our
# `discardValue` (atom 0xd7) is 0 or absent: FUN_18013fe00 stores our value at item
# +0x38, and the guard at 0x180141025 (`cmp dword [rbp+0x198],0` / `ja`) skips the
# local computation when it is non-zero. So today the client shows the real value
# while the server pays a made-up one, and the two disagree on every card. This
# makes the paid value agree with the shown value.
#
#   value = round_half_up(rating * price / 100)
#   level = 3 if rating >= 75, 2 if 65..74, else 1   (0x180141e8a..0x180141ea3;
#           derived from rating, NOT a wire field)
#   cardtype = FUN_1800d8330(cardsubtypeid), decoded from its jump table and
#           checked across every subtype 0..599 with zero disagreements
#
# ZERO WIRE CHANGE. Nothing new is sent; only the coin figure the server credits
# changes. Default off per the house rule, but this is the one patch worth
# defaulting on after a single verification.

# for a 75-rated rare gold (9,844,900 -> 9,845,500, exact) while the reveal screen
# showed "Quick Sell   0", and "Quick Sell all remaining Items" showed 0 too. So the
# figure was right and invisible, and the screen contradicted the wallet.
#
# The cause is the guard the table work reversed. FUN_18013fe00 stores our
# discardValue at item +0x38; at 0x180141025 a `cmp dword [rbp+0x198],0` / `ja` skips
# the client's own local computation when that value is NON-ZERO. We seed 0, so the
# client runs its own fcc_discardcoins lookup, that lookup returns no row for our
# cards, the price register stays 0, and it renders 0. WHY its lookup misses is still
# UNKNOWN and worth knowing, but it does not have to be answered to fix the display:
# sending a non-zero value bypasses the lookup entirely and the client uses ours.
#
# Freeze risk: low and in the safe direction. discardValue is a plain INT read by the
# scalar getter 0x1801c79d0. The freezes on this project have all come from feeding an
# object or array where a scalar was expected, never the reverse.
#
# Requires FUT_DISCARD_TABLE, since without the real table this would put the invented
