# FIFA17 UTAS Route Authority (economy cutover gate)

Machine-auditable ownership of every FIFA17 UTAS route that touches the economy
cluster. This is the **deployment gate** for the Rust economy cutover (R1/E1):
before Rust economy authority is enabled, every row's `Target` must be reached
and no `Python (proxied)` row may still write Core-owned state.

Cluster state = `coins`, owned inventory (`items`/`purchased`), unopened pack
entitlements (`unopenedPackIds`). `points` has **no** writer (read-only). EASFC
`powFunds` is a separate balance, out of cluster.

Legend: **R** = Rust/Core authoritative, **P** = Python proxied (oracle).
Evidence lines refer to `fifa17-recon/tools/{utas_server.py,fut_store.py}`.

## Writer routes (mutate cluster state)

| Route | Method | Python handler | Writes | Current | Target | Core primitive |
|---|---|---|---|---|---|---|
| `/ut/game/<sku>/match` | POST | `match_route`→`record_match` (fut_store 554) | coins | P | **R** | `grant_reward` |
| `/store/transaction` | PUT | `store_buy`→`open_pack`→`spend` (utas 3702) | coins, purchased, packsOpened, nextItemId | P | **R** | `purchase_entitlement` (+ `redeem_entitlement`) |
| `/purchased` | POST | `purchased_items`→`open_pack`+`consume_unopened_pack`+`move_items` (utas 3716) | coins, purchased, unopenedPackIds, items, nextItemId | P | **R** | `redeem_entitlement` |
| `/ut/game/<sku>/item/<id>` | DELETE | `quick_sell_url_route`→`quick_sell` (utas 1234) | coins, items, purchased | P | **R** | `sell_item` |
| `/ut/delete/game/<sku>/item` | POST | `quick_sell_route`→`quick_sell` (utas 1273) | coins, items, purchased | P | **R** | `sell_item` |
| `/ut/game/<sku>/item` | PUT | `item_route`→`move_items` (utas 1342) | items, purchased | P | **R** | `redeem_entitlement`/move (inventory-only) |
| `/ut/game/<sku>/trade/<id>` | POST/PUT | `trade_route` buy-now `spend`+`add_items` (utas 3895/3899) | coins, items, nextItemId | P | **R** | `purchase_item` (synthetic-seller mint) |
| `/auctionhouse`,`/transfermarket` | POST | `auctionhouse_route`→`list_for_sale` (utas 3865) | listings, nextListingSeq | P | **R** | listing-state (see note) |
| `/ut/delete/game/<sku>/trade/<id>` | DELETE | `delete_trade_route`→`remove_listing` (utas 3935) | listings | P | **R** | listing-state (see note) |
| `/ut/game/<sku>/squad` | PUT | `squad_route`→`save_squad` (utas 3430) | squads (item refs) | **R** (SquadReplace→Core) | R | Core squad tx (already migrated) |

Note (market listings): `listings`/`nextListingSeq` are the user's own sale pile;
the buyable auction inventory is **synthetic** (PACK_POOL-derived, not persisted).
There is **no** sale-credit, expiry-return, or fee (audit §5). Listing/cancel move
no coins and no ownership, so they are low-risk; a minimal durable listing store
(or keeping the synthetic-only model) is the market slice's only decision.

## Reader routes (emit cluster state; go STALE if Rust writes while these read Python)

| Route | Method | Python handler | Reads | Current | Target |
|---|---|---|---|---|---|
| `/user/credits` | GET | `credits_route` (utas 3765) | coins, unopenedPackIds count | P | **R** (`balance` + entitlement count) |
| `/userMassInfo` | GET | `massinfo` currencies (utas 578) | coins, points, record, items, unopenedPackIds, squad | P (`.squad` overlaid R) | **R** economy fields (coins/packs), squad already R |
| `/store/purchasegroup` | GET | `store_catalog`→`unopened_packs` (utas 3614) | unopenedPackIds | P + R topology overlay | **R** full-gen (catalog + SessionStore mode + Core entitlements) |
| `/tradePile` | GET | `tradepile_route` (utas 3911) | items, listings, coins | P | **R** (reads Core inventory/balance/listings) |
| `/hub`,`/tradePile/counts`,`/watchList` | GET | `hub_data`/`auction_counts`/`watchlist` | items, listings, coins | P | **R** |
| `/club`,`/club/stats`,`/user/list`,`/clubUser` | GET | club readers→`items` | items | **R** (`/club` Core-backed) / P others | **R** |

## Writer → Core primitive map (Phase 2)

| Python writer | Reachable | Core primitive (services::economy) |
|---|---|---|
| `spend` (pack buy leg) | YES | `purchase_entitlement` debit leg |
| `open_pack` | YES | `purchase_entitlement` + `redeem_entitlement` (buy→entitlement→open split) |
| `consume_unopened_pack` | YES | `redeem_entitlement` (consume-once) |
| `move_items` (purchased→club) | YES | inventory add within `redeem_entitlement` / move op |
| `add_items` (market mint) | YES | `purchase_item` (debit + mint) |
| `quick_sell` | YES | `sell_item` (remove + credit) |
| `record_match` (coins) | YES | `grant_reward` (credit) |
| `new_item_id` | YES | adapter numeric-id via `openfut-identity` (Core ids opaque) |
| `list_for_sale` / `remove_listing` | YES | listing-state (market slice) |
| `grant_coins` | **NO** (dead) | — drop |
| `grant_unopened_pack` | **NO** (test-only) | — drop |
| `save_squad` | YES | already Core-authoritative (SquadReplace) |

## Single-writer rule

Coins live **only** in Python `fut_profile.json` today (Core `clubs.coins` is a
separate imported value). Because every coin reader (`credits`, `userMassInfo`,
`tradePile`, market bodies) reads that same JSON, the coins cluster **must flip
readers and writers together** — a partial flip desyncs the client's counter
(audit "STALENESS RISK"). The coherent first cut is therefore the whole coins
bundle: 4 writer routes + `credits`/`userMassInfo`/`purchasegroup` readers, all
on Core, seeded by a one-time profile import into Core.

## Proxied-route safety (R1 requirement: no unsafe YES)

After cutover, every remaining `Python (proxied)` route MUST have
`economy state touched = NONE`. Routes with `economy state touched != NONE` are
part of the migration cluster and MUST be Rust before R1. This table is the
audit source; the host `classify()` is the enforcement point (NEVER BOTH).

## Cutover progress (2026-08-13)

Landed (Core authority + transport + first reader; classifier NOT yet flipped):

- **Core economy HTTP API** (`d32dc6e`): generic `/economy/{balance,entitlements,
  purchase-entitlement,redeem-entitlement,sell-item,grant-reward,purchase-item}`,
  server-side club resolution, atomic transactions. Core matrix green.
- **Host `CoreEconomy` client** (`d240a61`): typed reqwest transport, **fail-closed,
  no Python fallback** by contract.
- **`/user/credits` handler** (`handle_credits`): Core-backed, oracle-shape body,
  503 fail-closed. Tested via `FakeEconomy`.

**Not flipped:** `classify()` still routes every economy route to Python. Per the
single-writer rule the flip is one coherent barrier once ALL writers+readers are
implemented and Core is seeded — a partial flip would desync coins. Remaining
handlers: purchasegroup full-gen, userMassInfo economy, Store BUY, pack-open,
quick-sell, market buy/list/cancel, match reward; then the barrier flip +
differential/concurrency/restart + no-fallback classifier tests.
