"""The FUT card pool: the REAL FIFA 17 roster, 17,547 players.

WHAT CHANGED, AND WHY IT MATTERS
--------------------------------
This module used to hold 79 hand-written rows whose asset ids were mostly
invented, on the premise (from an older CARD_SYSTEM.md) that the client's card
map is empty offline so no id could ever render. That premise was wrong.

Card identity does not come from us. The client inserts every item we serve into
its CardsDb map and, just before that, merges in its OWN local players table
keyed on `resourceId & 0xffffff`. An invented id renders as a blank generic card;
a real one renders as a real player. Proven live: a pack showed SILVA and NOWAK
with real names, badges and flags beside three blanks at rating 50.

So the pool is now built from the game's own roster, extracted from a running
FIFA17.exe by tools/dbdata_extract.py into data/roster.json. It was cross-checked
against a completely independent method -- the sweep oracle in
tools/sweep_collect.py, which reads back the identity the CLIENT resolved -- and
573 of 573 overlapping names agreed exactly.

WHICH FIELDS ARE REAL AND WHICH ARE NOT. Be honest about this when reading a card:

    playerid   REAL   data/roster.json
    rating     REAL   same
    name       REAL   resolved by the client from the id; we never send a name
    club       REAL   we send teamid 0 and the client fills its own value
    nation     REAL   we send nation 0, same mechanism
    league     REAL   the client always recomputes leagueid on a DB hit
    position   PARTLY 59 ids are known (data/positions.json); the rest are
                      SYNTHETIC, assigned deterministically per id
    attributes SYNTH  derived from rating and position

The merge fills nation/teamid ONLY when they arrive as zero, and never touches
rating, position or attributes. That asymmetry is the whole design of this file:
send zero for everything the client knows better than us, and send our own value
only where the client has nothing.

THE MISSING COLUMNS, AND THE LEADS FOR THEM
-------------------------------------------
position / nationality / teamId / attributes are NOT in the rating index. Two
live sources exist and BOTH are per-materialised-card caches, not tables:

  * the 0x180-stride resolved card records (attributes + names), and
  * a 32-byte-stride keyed container, entries {playerId, position | hash<<32,
    rating, ?}, found at 0x42e8dbe8 inside the 238 MB heap region.

data/positions.json comes from the second one. Sweeping 5,000 ids did NOT
populate it, so it caches what the game itself materialises rather than what we
ask about. 59 entries survived validation (each entry's rating had to match the
roster's). Anyone extending this: a full-roster position source has not been
found, and the FUT rating index does not contain one.

Position codes are the standard FIFA enum, decoded against our own club cards
read live: GK 0, CB 5, LB 7, CM 14, LM 16, RW 23, ST 25, LW 27.

# Built 2026-08-05 from the game's own resident database (data/tables/*.json, dumped
# read-only by tools/db_dump.py, then tools/build_player_facts.py). Per player it
# carries the MEASURED position (players.preferredposition1), nationality, teamid,
# leagueid (via leagueteamlinks) and the six card attributes.
#
# The six attributes are not columns: they are a weighted sum of the 29 base
# attributes, and the weights come from the game's OWN `playerattributesmapping`
# table rather than from published formulas. The result checks out against real FIFA
# 17 cards: Messi 89/90/86/96/26/61 and Ibrahimovic 72/90/81/85/31/86 are exact,
# Suarez is one off on physical, Ronaldo within two on pace and shooting.
#
# NOTE THE REVERSAL on nation/team/league. When those fields were unknown we sent
# ZERO so the client would fill its own values (the merge fills them only when they
# arrive zero). Now that we hold the game's own numbers there is nothing to gain, and
# zeros actively HURT: our club-stats drill-downs bucket by the item's own nation and
