Quick-sell paid an invented five-tier rating ladder (its own comment said "PLACEHOLDER, not EA-authentic"). It was blind to card type and rareflag, so a 94-rated TOTW special and a 94-rated gold common both sold for 1500, and every non-player -- whose Core overall is 0 -- sold for the flat 150 floor. The ladder existed in three places (adapter wire, host payout, an integration test's private copy), which is a drift waiting to happen. Add openfut-adapter-fifa17::fut::discard: the client's own fcc_discardcoins table and its formula, round_half_up(rating * price / 100), keyed (cardtype, level, rare). All of it is already reversed in plan-2026-08-05-store-subsystem.md 3.6 and was verified there against 22 live club items, 22 of 22 exact. DISCARD_COINS is generated from fifa17-recon/data/tables/fcc_discardcoins.json and a test re-reads that file and asserts row-for-row agreement, so the transcription cannot drift. Collapse the three ladders into one method. ItemIdentityResolver::discard_value both stamps the wire discardValue and prices the sale, because a non-zero discardValue suppresses the client's local computation -- whatever is sent is what the player is promised. The host's quick_sell_value is deleted and the integration test's copy now calls the single implementation. A test with a resolver double returning an impossible price proves the credit follows the wire; reverting the payout to a ladder fails it. Gated on OPENFUT_FIFA17_DISCARD_TABLE=1, default off: switching revalues the real 1991-item club 10.5x (1,820,400 -> 19,128,955 coins if wholly liquidated), up for specials and DOWN for consumables, which the ladder overpaid 5.5x. That is an operator's decision. Staff decline to the ladder rather than pay 0: the client re-rates cardtypes 2/3/4/5/10 from its own DB and their rating is not imported. Deliberately not guessed -- see the falsifier in the doc. Verified on staging with the real club, both modes: flag off 1500 wire / 1500 paid; flag on 23760 wire / 23760 paid on an r99 rareflag-11 card (99*24000/100). Consumables price from their catalog rating and agree with the client's own computation. Adapter 244 lib tests, host 121 lib + 45 host_test, fmt and clippy clean.

⚠️ 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 Everything below this banner describes the superseded FIFA 23bridgelineage and is kept for historical context.Run the server (canonical):

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.
