Implements the standing requirement recorded in priority-2026-08 S5: the User-Agent filter is now the DEFAULT in the log tooling, not an option. The real client sends ProtoHttp; our own probes send curl/* or Python-urllib/*. Reading the log unfiltered gave this project a materially wrong picture of itself (/clubUser and /user/list had 93 and 180 hits, none from the game). The old futlog.py was a one-off with a hardcoded path and no notion of who made the request. Replaced with a real tool: timeline or summary, body/response display, path regex, time window, status filter, and an --unmapped view that lists the endpoints the client wants and we catch-all. --all and --probes exist for when you deliberately want our own traffic. Over the full 3044-request history: 486 requests came from the game. IT IMMEDIATELY CAUGHT ME OVERSTATING SOMETHING. Yesterday's commit called the PUT /item request shape "captured for the first time (the client had never successfully reached this path)". False. There are NINE client PUT /item requests in the log, eight of them during the failed attempts, every one carrying swap and tradeId: 08:45:11 08:51:13 08:55:21 08:58:19 09:10:52 09:15:26 09:22:31 09:37:12 | 11:15:48 The request was on the wire and in the log the whole time. What was new was reading it. Same class of error as the truncated decompile in S16: evidence already collected and not looked at. REBUILD_RESEARCH S17 corrected.

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.
Repositories
| Repo | Purpose |
|---|---|
openfut-core |
Game-independent offline FUT backend |
openfut-bridge |
FIFA 23 integration layer + reverse-engineering proxy |

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.
