openfut.cfg is not the source of truth for the client's Blaze ports -- the launcher
is. It reconciles openfut.cfg from ~/.config/openfut-launcher/config.json,
fail-closed, immediately before every launch. So `staging` set the ports, verified
them, and the next launch silently reverted them.
Caught only because the capture harness cross-checks instead of trusting the screen.
The operator reported "the Transfers tile does not show Sold" -- which looked like a
clean negative result about the sold counter, and was in fact a reading of their
PRODUCTION club, where sold:0 is correct. Evidence chain:
* route-log delta contained 5 lines, all of them the harness's own GETs; the
client issued nothing to staging at all;
* `ss -tnp` on the client showed FIFA17.exe pid 39482 ESTAB to 10.10.0.120:42130
(production Blaze) plus TIME-WAIT to :8099 (production UTAS);
* the hook logged `blaze_redir=42127 blaze_main=42130`;
* openfut.cfg mtime was 2s before process start, sha back to the production value.
Had the harness reported the tile at face value, the sold counter recovered from
CardsDLL would now be recorded as refuted by a run that never reached the code.
Fixes: own the launcher config (source) before openfut.cfg (derived), with the same
record-before-mutate sidecar discipline on both; refuse to edit while the launcher is
running, since it holds config in memory and would write the stale values back;
report both files and both guards in `show`. launcher_running() matches the
kernel-truncated comm "openfut-launche" -- the full name exceeds 15 chars, which has
bitten this project before.
No production change; staging stack and its variant-A sold row untouched.
OpenFUT
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.

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.
