Staff quick-sell could not be priced correctly: for cardtypes 2/3/4/5/10 the
client overwrites the rating and rare flag we send with values from its own card
database, and a staff wire record carries no rating, no rareflag and no
discardValue at all. The server had no way to know the displayed price from what
it sent, so pricing declined for staff and fell back to the placeholder ladder.
The missing input was read straight out of the running client (pid 6580), no UI
interaction required:
* tools/coach_probe.py grades all four resident staff records HIT, which by
construction requires record +0xb4 == the table's `value` and +0x58 == its
`rare`. That settles `value`-is-the-rating, which was previously an inference
and was deliberately not shipped on that basis.
* tools/discard_probe.py (new) reads both discard slots -- +0x38, the value we
sent, and +0x3c, the value the client computed for itself:
1000509 sub 4 ct 2 rat 88 rare 1 sent 0 calc 282 predicted 282
9000081 sub 6 ct 10 rat 66 rare 0 sent 0 calc 36 predicted 36
3000083 sub 8 ct 4 rat 66 rare 0 sent 0 calc 36 predicted 36
4 of 4 agree, 0 disagree. 36 on the value-66 GK coach was the exact falsifier
written for this last commit.
Entities::enrich_staff now fills rating from `value` and rareflag from `rare` for
the five staff families, and the catalog emits the real rareflag instead of a
hardcoded 0 (it is not cosmetic -- it selects the discard price column, which is
why the rare-1 manager prices at 282 and a rare-0 coach at 36). Players and
consumables are untouched; their wire values are authoritative.
Verified on staging: a GK coach quick-sells for 36, not the 150 floor. The
catalog diff is exactly the two coach entries gaining rating 66; 1710 entries in
and out, nothing else changed.
The same probe shows what production does to PLAYERS today: every resident player
carries sent+38 = 1500, which suppresses the client's own computation, against a
real 688..752 for a gold rare and 72,800 / 74,400 for the two legends.
Still open, and not a discard problem: manager fifa17_1000509 is owned in Core
but has no catalog entry or definition (it reaches the client through the opaque
squad extension), so it declines to the ladder. That is definition coverage.
Importer 41 tests, fmt and clippy clean.
OpenFUT
⚠️ Status — see
docs/PROJECT_STATE.md(canonical). The working, actively-developed target is FIFA 17, not FIFA 23. Everything below this banner describes the superseded FIFA 23bridgelineage and is kept for historical context.Run the server (canonical):
cd fifa17-recon/docker/fifa17-python && docker compose up -d— seefifa17-recon/FUT-RUNBOOK.md.openfut-coreis the shared offline backend (still used by the FIFA 17 path);openfut-bridgeis the retired FIFA 23 integration.
Offline Ultimate Team — like SPT, but for FIFA 23.
OpenFUT replaces EA's retired FUT servers with a fully offline, single-player backend. You own FIFA 23 legitimately. You just want to keep playing after EA shut down the servers.

SQLite database
Core is game-independent. It speaks a clean REST API and knows nothing about FIFA 23 internals.
Bridge is FIFA-specific. It speaks FIFA 23's wire protocol and translates it into Core API calls. Bridge is where all reverse engineering work happens.

Design Principles
- Offline-first. No EA account required. No internet connection needed.
- Single-player only. This is not a multiplayer server emulator.
- Data-driven. All cards, packs, SBCs, and objectives are JSON files. Everything is moddable.
- Clean architecture. Core has zero knowledge of FIFA 23. Bridge has zero game logic.
- No copyrighted assets. No real player images, no EA trademarks in data files.
