funman300 3c67fea074 feat(fifa17): serve the consumable quick-sell (PUT item/resource/<rid>)
Fixing the display was only half of it. Quick-selling a consumable from the
repaired screen produced "There was a problem communicating with the FIFA
Ultimate Team servers", because the client's consumable quick-sell is a route
neither stack had ever served:

    PUT /ut/game/fifa17/item/resource/5003068     body_len=0

Live-captured on staging. That path now carries three verbs -- GET is the
definition lookup, POST applies the consumable (ApplyCardByRes), PUT quick-sells
it -- and it is keyed by the stack's RESOURCE id, not an owned instance, unlike
the player quick-sell (DELETE item/<instanceId>).

This had to be Rust-owned rather than proxied: the Python oracle maps
item/resource method-agnostically to its definition route, so on production --
where the oracle is alive -- a PUT would return 200 with a definition list and
sell nothing, and the client would show a successful sale of a card the player
still owns.

Implementation reuses the retail-proven quick-sell path verbatim
(handle_quick_sell_path), so pricing comes from the same
ItemIdentityResolver::discard_value that stamps the number on the stack. Display
and payout are the same call; they cannot drift.

Two decisions, both documented in the code as decisions rather than discoveries:

  * ONE copy per request. The request carries no quantity, and the screen prices
    a CARD, so consuming a whole stack on one keypress would pay one card's
    price for N cards. Selling one is the conservative reading.
  * The copy sold is Core's first matching owned instance -- the same one whose
    wire id the consumables screen already published as the stack's `item`, so
    the player sells the card they were shown.

Verified against the running staging host:
    displays 38 -> PUT -> coins +38, owned -1, consumables -1, stack 2 -> 1
    replay sold the one remaining copy (+38, -1), no double credit
    exhausted -> 404 not_owned, coins +0, owned +0 (no phantom payment)

123 host tests (+1 locking all three verbs on the shared path, and that the bare
`item` PUT stays the pile move), clippy -D warnings clean, fmt clean.

openfut-utas-host

The FIFA 17 UTAS migration boundary. It accepts the client-visible HTTP surface, serves migrated routes from Rust/Core plus host-owned durable stores, and proxies only the unclassified tail to the Python behavioral oracle.

FIFA 17 ──HTTP──▶ openfut-utas-host
                    ├── migrated route ──▶ Rust adapter / Core / host stores
                    └── unclassified tail ──▶ Python UTAS oracle

src/lib.rs::classify is the route-level source of truth. The current Rust surface includes club/squad/user reads, club rename, auth/session/client data, Store/economy, packs, owned-item moves, market/trade-pile, and the observed hub support routes.

Safety model

  • Classification happens exactly once before execution. There is no "try Rust then Python"; a mutation cannot be double-applied.
  • A route classified to Rust never falls back to Python on a Core/store/projection failure. Each handler uses its captured fail-closed or honest-empty wire contract.
  • PUT …/club and PUT|POST …/user/club atomically update the shared account JSON. Every input returns the required zero-atom 200 {} response; rejection and persistence failures remain visible in logs.
  • Numeric GET …/squad/<n> returns the one Core-backed current squad, matching the Python oracle's single-current-squad behavior.
  • Python remains the behavioral oracle and rollback backend for routes not yet classified to Rust. New economy behavior belongs in Rust/Core, never Python.

Configuration (env)

Var Required Default Meaning
OPENFUT_UTAS_HOST_ADDR yes client-visible host listen address
OPENFUT_UTAS_PYTHON_URL yes Python oracle base for the unclassified tail; must differ from this host
OPENFUT_FIFA17_CATALOG yes FIFA 17 definition identity catalog
OPENFUT_IDENTITY_STORE yes persistent owned-instance ↔ wire-id store
OPENFUT_PERSONA_ID yes non-zero FIFA persona id shared by LSX/Blaze/POW/UTAS
OPENFUT_MARKET_DB yes durable host-owned transfer-market SQLite DB
OPENFUT_PILE_DB yes durable host-owned item-pile SQLite DB
OPENFUT_CORE_URL no http://127.0.0.1:8080 OpenFUT Core base
OPENFUT_FIFA17_TABLES_DIR no fifa17-recon/data/tables FIFA entity tables
OPENFUT_CLIENTDATA_DB no identity-store sibling clientdata.json durable opaque client-data JSON
OPENFUT_ACCOUNT_PATH no FUT_ACCOUNT_PATH, then identity-store sibling active_account.json shared FIFA account/club JSON

Startup fails if required identity or durable economy state cannot be opened. No placeholder production identity source is substituted.

Identity model (resolved)

FIFA renders an owned card by resolving resourceId & 0xffffff against the client's own local players table; an invented id renders a blank generic card (proven live — fut_cards.py:11-21). Two distinct identities, never conflated, are resolved by [Fifa17IdentityResolver] (the single production path):

  • Definition identity (resourceId/assetId) — the card's real FIFA asset id, from the versioned OPENFUT_FIFA17_CATALOG. An unmapped definition is dropped and counted, never faked.
  • Instance identity (id) — a stable, persistent, reversible wire integer from the generic openfut-identity store under the FIFA 17 wire-id policy (monotonic from 100_000_001). The same owned instance keeps its id across restart and reverses exactly; two copies of one definition share a resourceId but get distinct ids. The namespace is globally monotonic within (fifa17, owned-item) — no per-account column is needed because Core owned-instance ids are globally-unique UUIDs.

Production has a frozen post-P1 baseline and a hot Python rollback. A source change passing local tests is not deployment approval. Build verification, staging, host restart, and live-client promotion remain operator-gated; the current state and promotion evidence live in the OpenFUT Obsidian vault.

Logs are safe by construction: no auth/session/device/token material — only owner, route, filter summary, counts, status.
