OpenFUT Agent

Closes the market correctness gap: handle_market_list recorded listing.card_id from the raw FIFA wire resourceId, so a synthetic buy minted a card_id Core could not resolve — it survived the immediate response but Core's content preflight rejected it on reboot. - catalog.rs: keep the by_resource reverse index (was built then discarded) and expose `card_id_for_resource(resource_id) -> Option<&str>` — exact reverse of the card_id->asset catalog, no heuristics, unknown => None. - lib.rs: `impl MarketCardResolver for Fifa17IdentityResolver` delegates to the same catalog /club shaping uses; Core never sees a FIFA resource id. - market_store.rs: listings now carry BOTH `card_id` (authoritative Core content, what a buy MINTS) and `wire_resource_id` (the FIFA wire id, echoed in the auction record). New column; create_listing takes both; row/Listing updated. - market.rs: `MarketCardResolver` trait; handle_market_list resolves resourceId -> Core card_id and fails closed (persists nothing) on an unmappable resource; auction_record emits `resourceId` from wire_resource_id. Dispatch passes the resolver. Tests: list_unknown_resource_fails_closed_no_listing (B), list_persists_core_card_and_wire_resource_across_reopen (C), catalog reverse lookup; and the dispatch E2E now RESTORES the full Core+store restart (economy_full_sequence_through_dispatch_and_restart) — the synthetic buy mints a real reverse-mapped card_id, so Core's content preflight passes on reboot (A+D). market 23 lib + catalog 15 + 2 integration green; clippy -D warnings + fmt clean.
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.

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.
