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)

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.
