RETRACTION. This repo claimed, in REBUILD_RESEARCH S14c and in utas_server's
item_route comment, that FutMoveCard 0x180128600 "HAS NO SKIP HANDLER
(FUN_180135ff0 appears zero times, unique among FUT deserializers)" and "parses
only itemData -> dreamSquads". Every part of that is false. Full decompile:
FUN_180135ff0 call sites : 2 (offsets 5006, 6080)
atoms parsed : 7 active dreamSquads id itemData pile reason success
Cause: the decompile was written out as src[:4000] and then searched. The function
is 6193 chars, so BOTH skip-handler call sites and four of the seven atoms lay past
the cut. An absence was reported from a truncated listing -- the same failure mode
as the Memory.getBytes bytearray scan that silently returned zero hits. Never
conclude an absence without asserting the searched region covers the function.
Cost: the false claim implied "any extra key desyncs this parser", which sent the
investigation after client-side state for seven attempts, and the derived premise
"the deciding factor is client-side state, not the wire" was wrong too.
VERIFIED SHAPE. PUT ut/%s/item is not an ack endpoint; it returns per-item VERDICT
records:
id(0x15c) INT 0x1801c79d0 -> record+0x00
pile(0x226) STRING 0x1801c7aa0 -> enum 0x180142650 (club=7 purchased=6 trade=5)
success(0x2fa) BOOL 0x1801c7620 -> record+0x0c
reason(0x279) STRING -> "Destination Full" = 0xf
dreamSquads(0xe9) INT array; else -> FUN_180135ff0 (skip)
The completion handler raises EVENT_CARDS_MOVE_CARD_FAILURE when the record vector
is EMPTY or record+0x0c != 1, and success is initialised to '\0' per element. So
every body ever returned reported the move as FAILED, {} included. Quick sell
survives an identical {} because its callbacks read only the transport code and
ignore the body -- that is the whole asymmetry, and it was on the wire after all.
STAGED, NOT DEFAULTED. FUT_MOVE_BODY=ack emits the correct shape; the default stays
`empty` because sufficiency is untested. One launch settles it.
The ack is answered BEFORE the `if moved:` gate: under FUT_PACK_AUTOCLUB=1 the
cards are already in the club when the reveal asks to move them, so move_items()
returns nothing and a moved-derived body would be zero-record -- failing in exactly
the configuration ack exists to fix. Caught in review before it ran. success is
asserted only for ids that were moved now or are already in the club; anything else
gets an honest success:false rather than an invented verdict.

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

openfut-core |
Game-independent offline FUT backend |

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

# 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.
