Opens the 409 `apply_effect_unproven` gate for attribute training, the second family after contracts to have its effect settled rather than merely its magnitude. `ApplyEffect` replaces the single-family `AddContractMatches` struct: Core dispatches on `kind`, so an unproven family must be impossible to express, not merely discouraged. The shared half of an apply -- the exactly-once key, Core's transaction, the error mapping and the client's payload -- is now one `finish_consumable_apply`, so a new family cannot quietly acquire its own idempotency format or its own success shape. Two refusals are training-specific and both prevent silent corruption rather than merely being tidy: a non-player target has no attributes to write, and a cross-class target would train a different attribute from the one printed on the card, because a keeper's slots mean DIV/HAN/KIC/REF/SPD/POS where an outfielder's mean PAC/SHO/PAS/DRI/DEF/PHY. `attributeList` now prefers Core's `effective_attributes` and only falls back to the immutable definition when Core does not send them -- reading the definition regardless would silently drop every applied training off the card the client draws. Tests pin the verb split on `item/resource/<rid>` (POST applies, PUT stays quick-sell, GET is not an economy route at all), the digit guard, the exact JSON Core deserialises for both effects, and that no shipped training card exceeds the ceiling the host declares to Core.

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 Everything below this banner describes the superseded FIFA 23bridgelineage and is kept for historical context.Run the server (canonical):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

# Start the proxy (for traffic capture / FIFA integration)
cd openfut-bridge

Core listens on http://127.0.0.1:8080 by default.
Bridge listens on http://127.0.0.1:8443 by default.
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.
