funman300 3c28b0d1af feat(fifa17): apply training cards, and project trained attributes
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.

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 Everything below this banner describes the superseded FIFA 23 bridge lineage and is kept for historical context.

Run the server (canonical): cd fifa17-recon/docker/fifa17-python && docker compose up -d — see fifa17-recon/FUT-RUNBOOK.md. openfut-core is the shared offline backend (still used by the FIFA 17 path); openfut-bridge is 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.

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.

Running

# Start the offline backend
cd openfut-core
cargo run

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

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.
