Migrate GET club/stats/staff from the Python proxy to a Rust static handler.
The production oracle returns {} for the staff-bonus stat set (deliberately
empty); the Rust host now owns it (owner=RUST route=club-stats-staff). Updates
classify(), the pre-existing near-miss test (now club/stats/year), the ownership
matrix test, and the no-fallback integration test. club/stats/{year,consumables}
remain Python (aggregation) pending the Core-derived club-stats migration.
Through real handle_with_ip dispatch against live Core:
- pure_economy_routes gains the retail v2 Store family (transaction/0,
purchasegroup, purchased GET/POST) so NEVER-BOTH + no-fallback assert them
Rust-owned (Python proxy count 0) and fail-closed 503 on dead Core.
- Part-7 repro: PUT /ut/v2/game/fifa17/store/transaction/0 returns a Rust
createPackResponse + debits Core (NOT the Python TRANSACTIONCANCEL no-op).
- retail_v2_store_flow_matches_v1_through_dispatch: v1 and v2 BUY of the same
pack debit + mint identically; v2 purchasegroup + reveal Rust-owned.
Live staging (S2) showed the retail FIFA17 client issues the Store family
under /ut/v2/game/<sku>/... (PUT /ut/v2/game/fifa17/store/transaction/0),
which escaped Rust economy authority to Python. Fix classify_economy:
- ut_tail() normalizes both /ut/game/<sku>/ and /ut/v2/game/<sku>/ to the
same tail (generic sku, never hard-coded fifa17); delete family likewise
accepts /ut/v2/delete/game/.
- StoreBuy matches store/transaction and store/transaction/<digits> via a
bounded is_store_transaction_tail (never store/transactions, ...foo, or
.../<id>/extra), mirroring the Python bare /store/transaction regex.
Adds table-driven ut_tail + is_store_transaction_tail + classify_economy v2
unit tests (lib 74).
barrier_never_both_no_fallback_and_stale_reader drives the REAL post-barrier
handle_with_ip against a live in-process Core + a mock Python upstream that
counts every request and answers with a coins=111 marker:
- STALE READER: credits + userMassInfo show the Core balance, never 111
(userMassInfo proxies the Python envelope but the Rust economy overlay wins).
- NEVER BOTH (Core up): every pure economy route returns a Rust body (no
__python__ marker) and the Python proxy call-count stays 0.
- NO FALLBACK: a server pointed at a dead Core port (built without probing Core:
empty catalog + empty pool) fails closed (credits/match -> 503) and STILL never
proxies to Python (call-count unchanged).
Also parametrizes build_econ_server's pass URL so the mock upstream can be
injected. host 71 lib + 4 integration + differential + concurrency + failure +
24 host_test all green; clippy -D warnings + fmt clean.
The economy authority barrier. `handle_with_ip` now dispatches every
economy-touching route to Rust/Core via `try_handle_economy` BEFORE consulting
`classify()`, so a migrated route can never also reach the Python passthrough
(NEVER BOTH). With economy services wired (production `from_config`) an economy
route ALWAYS returns Some — fail-closed 503 on any Core error — so there is no
Python economy fallback. `userMassInfo` stays a hybrid by design: Python
supplies the non-economy envelope; Rust overlays BOTH the squad and the economy
fields (coins + unopened-pack count from Core), so no stale Python economy value
is visible.
Routing only — no handler/test changes buried here. Routes now Rust-owned:
/user/credits, /store/purchasegroup, /store/transaction, POST+GET /purchased,
PUT /item, item DELETE forms, /match (ut/delete), /auctionhouse, /tradePile,
/trade, ut/delete trade; plus the userMassInfo economy overlay.
openfut-import-fifa17/tests/durable_import.rs drives the REAL import pipeline
(analyze -> Report dry-run; emit_content; plan_apply -> GenericImportRequest +
deterministic identity mappings + watermark; the staging/preflight/seed/
post-validate gates over a real JsonIdentityStore; openfut_core::services::
import::apply_profile_import in one Core SQLite tx) against a disposable
temp-file Core DB, from a small sanitized in-test fixture (750000 coins, 3
resolvable base players, unopenedPackIds [70,70,101], one squad).
Five ordered steps on one durable target, all green:
A dry-run: report exposes persona/coins/inventory/unopened/fingerprint; ZERO
DB mutation (all Core tables COUNT=0, identity store empty).
B apply: coins=750000 exact, owned=3, packs=3 (opened=0), squad_players=2,
deterministic owned ids, import_fingerprint recorded, identities reverse-
resolve both ways, watermark=100000600.
C restart: close+reopen the SAME sqlite file -> identical state.
D re-apply same source -> AlreadyImported (fingerprint), no doubling.
E conflict (coins 750000->750001 flips the fingerprint for the same game)
-> apply fails closed ('different source'); DB unchanged.
Fingerprint = FNV-1a-64 hex of the source snapshot, carried into
ProfileImportRequest.source_fingerprint = Core profiles.import_fingerprint, the
per-game rerun-identity key. dev-deps added to openfut-import-fifa17
(openfut-core path, tokio, sqlx). No production/live data.
economy_differential.rs boots the REAL Python oracle (fifa17-recon/tools/
utas_server.py) as an isolated subprocess (env FUT_PROFILE/FUT_ACCOUNT_PATH/
FUT_PORT into a temp dir + loopback port; no production container/port/save;
killed on Drop) AND the real Rust stack (seeded in-process Core + a real Server
with EconomyServices), seeds a semantically-aligned fixture on both, and drives
16 ops through the REAL surfaces (oracle over HTTP; Rust via
Server::try_handle_economy on the off-runtime thread).
Result: 15 PARITY, 1 DIFFERENT-BY-DESIGN.
- PARITY: credits, userMassInfo economy, purchasegroup (pack70/sentinel/clean-v1
incl. the real SessionStore capability handshake), Store BUY, POST /purchased
open, GET /purchased reveal (VERIFIED: durable single-profile purchased pile
on BOTH — the hypothesised per-SID cache does NOT exist, so PARITY not
DIFFERENT-BY-DESIGN), quick-sell (both forms), move, match WIN (+400 byte
shape), market list/query/cancel.
- DIFFERENT-BY-DESIGN: market second-buy. First buy debits buyNowPrice + closes
on both. Rust's MarketStore is a crash-consistent single-debit ledger (second
buy of a sold listing = no-op, pinned by assertion); the oracle's buyable
market is a stateless PACK_POOL sample that re-debits on repeat. Compat impact
NONE (buy-now is one-shot); Rust is a strict correctness improvement.
No Python source changes; no classifier changes. Deterministic (3 runs).
Two real host-dispatch test files (no fakes) driving Server::try_handle_economy
against a live in-process Core over the real blocking client + durable
MarketStore/PileStore + JsonIdentityStore, each racer its own OS thread
(off-runtime pattern).
economy_concurrency.rs — 8 races x 50 iterations:
A two BUYs (coins for one) -> exactly one 200 + one 461, final 0, one debit.
B duplicate owned-pack open -> one redemption, +11 once, entitlement once.
C duplicate quick-sell -> one sell + one credit + one removal.
D two market buyers -> one win, one debit, one mint, sold once.
E reward+BUY -> no lost update (Core relative UPDATE under BEGIN IMMEDIATE).
F move+quick-sell / G list+quick-sell -> one coherent transition.
H 1000 concurrent mints -> unique + reversible wire ids, monotonic watermark.
economy_failure.rs — 10 fault-injection sub-cases, all fail-closed:
BUY/open-redeem/generator/pile/identity, quick-sell, move, market
reserve/purchase/complete. CRITICAL complete-sale-after-commit = SAFE: the
listing is left `reserved` (not active), so the active->reserved reserve CAS
can never win again -> not buyable, exactly one debit + one mint. No E3.
Fault injection uses test-file CoreEconomy/ExternalIdentityStore doubles plus a
NARROW, inert-by-default `StoreFault` seam in market_store.rs + pile_store.rs
(the concrete stores have no trait boundary; 3 `tripped()` checks + a field,
zero behaviour unless a test arms it). `parking_lot` promoted to a normal dep
(the seam's Mutex is used at lib scope). Classifier/ROUTE_AUTHORITY/Python
untouched. host lib 71/71; both new tests pass.
Wire the PRODUCTION constructor so the economy authority is not test-only.
Server::from_config now builds one process-lifetime AsyncBridge, opens the
durable MarketStore + PileStore (paths from config), shares one HttpCoreClient
as both CoreAccess and CoreEconomy, builds the content pool from Core, and
attaches EconomyServices via with_economy. Stores/bridge are host-lifetime, never
per request.
- config.rs: required OPENFUT_MARKET_DB / OPENFUT_PILE_DB (durable file paths;
must survive host restart — no temp defaults).
- Fail-closed startup: a bridge/store that cannot initialize returns Err from
from_config (host refuses to start) — NEVER a silent omission or a Python
economy fallback.
Test: from_config_constructs_and_serves_economy — builds the Server via the REAL
from_config (disposable config: temp market/pile/identity + a catalog file
derived from seeded content + the real tables dir) against a live Core, drives
credits / purchasegroup / Store BUY / market list-query-buy through it, then
rebuilds from the SAME config after a Core restart and asserts the balance
persisted. host 71 lib + 3 integration + 24 host_test green; clippy/fmt clean.
Closes the reveal contract gap: POST /purchased opens a pack and returns
metadata; the client then polls GET /purchased for the opened items. Store BUY
returns items inline, but owned reward-pack (e.g. pack 70) opens had no reveal
read path, so a real FIFA session would show nothing after opening.
Faithful to the Python oracle (fut_store.last_pack / purchased pile): the reveal
is the set of owned items currently in the FIFA "purchased" pile — durable,
idempotent on repeat GET, cleared per-item when a card is moved to the club, and
appended-to by each open. Not a replay cache; presentation state derived from
the durable pile store + Core inventory.
- pile_store.rs: `list_by_pile(pile) -> Vec<core_item_id>` (reveal membership).
- economy_store.rs: `PurchasedPileSink` trait + optional `StoreDeps.purchased`;
handle_store_buy/handle_pack_open record each minted item into the "purchased"
pile. `shape_purchased_reveal` (pure): filter Core inventory to the purchased
pile, shape with the SAME `shape_club_response` /club uses. Grants nothing,
consumes no entitlement, allocates no id, moves no coins.
- lib.rs: EconomyRoute::PackReveal + classify_economy (GET purchased);
BridgedPurchasedSink (records via the runtime bridge from the sync dispatch
thread); dispatch reads the pile async + Core inventory sync + pure-shapes.
Scoping: single fifa17 profile/club (like the Python oracle), so all sessions
share one purchased pile — DIFFERENT-BY-DESIGN vs a per-SID cache, matching the
oracle's single-profile model.
Tests: pile_store::list_by_pile_filters_and_reflects_moves; and the dispatch E2E
now opens pack 70 (entitlement seeded via the Core economy API) and asserts GET
/purchased reveals the opened items and is idempotent on repeat. host 71 lib +
2 integration + 24 host_test green; clippy -D warnings + fmt clean.
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.
Records the AsyncBridge + classify_economy + try_handle_economy dispatch
(unrouted) and the economy_full_sequence_through_dispatch E2E, the
reqwest-blocking-in-async fix (off_runtime), and narrows Remaining to: Python
differential, host concurrency matrix, failure injection, importer, then the
from_config attachment + classifier barrier + reachability proofs. Flags the
two market-handler gaps (resourceId->card_id mapping; GET /purchased reveal
cache).
Bridges the synchronous thread-per-connection host to the async
transfer-market/pile handlers WITHOUT flipping the classifier. classify()
is untouched; production still proxies every economy route to Python. The
new dispatch is exercised only by the integration harness via
Server::try_handle_economy — handler wiring, not authority cutover.
async_bridge.rs: AsyncBridge owns ONE process-lifetime multi-threaded Tokio
runtime, shared by every connection via Arc. block_on() runs a future from
the sync dispatch thread; if invoked from within an ambient runtime it
offloads onto its own runtime + a std channel instead of panicking
("cannot start a runtime from within a runtime"). 4 unit tests incl. the
nested-runtime-safety case and concurrent multi-thread drivers.
lib.rs: EconomyRoute + classify_economy (mirrors the Python route table:
credits, purchasegroup, store/transaction, purchased, item DELETE/PUT,
ut/delete match/item/trade, auctionhouse/transfermarket, tradePile, trade).
EconomyServices (Core econ transport + durable MarketStore/PileStore + the
bridge + the pack-content pool), attached via Server::with_economy (kept out
of `new`/`from_config` so existing tests build a DB-less Server; production
from_config attachment is the barrier step). Server::try_handle_economy
dispatches: sync handlers (credits/purchasegroup/store-buy/pack-open/
quick-sell/match) inline; async handlers (market list/query/buy/cancel,
move) on the bridge via owned `async move` blocks. build_content_pool
derives the resolvable FIFA∩Core candidate pool from Core content.
market.rs: FIX the load-bearing hazard the FakeEconomy tests missed — the
async market handlers call the BLOCKING reqwest Core client, which panics
(reqwest::blocking::wait::enter) when run while a Tokio runtime is entered.
off_runtime() hops each Core call to a fresh OS thread with no runtime
entered, so blocking is legal. handle_move_items resolver gains `+ Sync`
(future must be Send for the bridge).
tests/economy_integration.rs: economy_full_sequence_through_dispatch drives
the WHOLE cluster through the REAL Server dispatch + bridge against a live
in-process Core (seeded with fifa17 dev content: 100k coins + owned cards),
on a plain OS thread (direct bridge path), over the real blocking
HttpCoreClient — no fakes: Store BUY (pool draw + shape + debit 400 + mint 5),
credits, quick-sell (reverse-resolve + credit), match WIN (+400), market
list->query->buy->query(sold)->second-buy-fails(no double debit), cancel
(cancelled not buyable), move-items, then reopen the durable market/pile
stores from disk (sold + pile persist). Deterministic. start_core_seeded
loads fifa17 dev content so /collection renders real definitions.
Tests: host 68 lib (+4 bridge) + 2 economy_integration + 24 host_test, all
green; adapter unchanged-green; clippy -D warnings + fmt clean.
Update cutover progress: Store BUY/pack-open/quick-sell, market
list/query/cancel/buy + move-items, durable listing/pile stores, and the
pack-content generator are implemented + tested (4d2b8b9) but NOT routed.
Remaining before the single classifier barrier: sync<->async Server wiring +
classify() routes, host<->Core writer E2E, Python differential, host
concurrency matrix, importer restart/idempotency, then the barrier + no-fallback
proofs.
The fresh-DB write-lock race is fixed (core fbb54ea: BEGIN IMMEDIATE writes),
so the E2E+restart harness now uses max_connections=5; 10/10 deterministic.
Complete the transport contract: purchase_items (atomic debit + mint N) on the
CoreEconomy trait + HttpCoreClient (POST /economy/purchase-items) + FakeEconomy.
This is the open-on-buy primitive the Store BUY handler will use (createPackResponse
returns the minted itemList). Fail-closed like the rest of the client.
WAL-establish-once + busy_timeout (core 75b1830) reduced but did not eliminate a
brand-new-DB multi-connection warm-up 'database error'; the E2E+restart harness
stays on a single serialized connection for determinism, and the residual
multi-connection concurrency issue is documented as the remaining Part-T blocker.
Serialize Core access with a single pooled connection (the harness drives Core
sequentially via the blocking client) to avoid a WAL-mode-establishment race
across connections warming up on a brand-new DB file, and raise the readiness
ceiling for heavy parallel test-binary load. 10/10 deterministic. (Fixed
alongside a real Core robustness fix: per-connection pragmas + busy_timeout,
core 0360135.)
Spawn Core (axum) on an ephemeral loopback port backed by a disposable temp-file
SQLite, seed a fifa17 profile via the real Core HTTP API, then drive the HOST's
REAL transport (HttpCoreClient: CoreEconomy) + handlers against it — no fakes:
credits reads Core balance; match-reward writer credits via Core grant_reward;
purchasegroup full-gen renders the owned pack from a Core entitlement (no
sentinel); userMassInfo overlay derives coins from the same Core state
(credits==massinfo==Core invariant). Restart phase reboots Core from the same
on-disk DB and proves coins + entitlements persist. Temp dir + 127.0.0.1:0 only;
no prod DB/ports/containers/.105. dev-deps: openfut-core, tokio, axum.
Carry unopenedPackIds through the importer: Profile model -> Report ->
ApplyPlan. GenericImportRequest now emits entitlements[] (one definition_id
per unopened pack instance, order+duplicates preserved), which Core's import
seeds as unconsumed packs rows in the same transaction. Closes the economy
import gap so a migrated profile's unopened packs become Core entitlements
(feeding purchasegroup/credits/userMassInfo). Idempotency unchanged (import
fingerprint). +1 test; 26 pass, clippy -D warnings clean.
All Core-backed, fail-closed (503, never Python), NOT yet classifier-routed
(coherent barrier pending full cluster + Core seed):
- handle_purchasegroup: full Rust body from Core entitlements + StoreMode via
the oracle-fixture-tested build_purchasegroup (no Python body dependency).
- overlay_massinfo_economy: set userInfo.currencies coins + unopenedPacks
recoveredPacks from Core, preserving all other fields.
- handle_match_end + build_match_reward_body: derive outcome from endReason,
credit via Core grant_reward, oracle-shaped destroy_match_body.
Invariant test: credits == userMassInfo == purchasegroup all read one Core state.
7 new host tests (+ FakeEconomy write methods honor fail flag).
Add CoreEconomy transport (trait + HttpCoreClient impl over Core /economy/*):
balance, entitlements, purchase_entitlement, redeem_entitlement, sell_item,
grant_reward, purchase_item. Fail-closed by contract: any transport/status/parse
error surfaces a controlled error and NEVER falls back to Python (a fallback
would be a second writer).
Add the credits reader vertical: build_credits_body (byte-shape-identical to the
Python oracle: credits + currencies[].funds/finalFunds + optional
unopenedPacks.recoveredPacks) and handle_credits (coins = Core balance,
recoveredPacks = Core entitlement count; 503 fail-closed on Core error). Not yet
classifier-routed: the coins cluster flips as one coherent barrier once every
writer+reader moves together and Core is seeded. FakeEconomy double + 3 tests
(oracle shape, Core-backed read, fail-closed).
Advance openfut-core gitlink to d32dc6e: generic /economy/* HTTP routes over
services::economy, server-side club resolution (game-scoped active profile, no
client-supplied club id), + list_unopened_entitlements reader. This is the
transport the FIFA17 economy cutover binds to. Core matrix 43 lib + 115
integration green; clippy clean; boundary audit clean.
Machine-auditable ownership table for every FIFA17 UTAS route touching the
economy cluster (coins/inventory/entitlements), plus the writer->Core-primitive
map and the single-writer rule. Grounded in the Python economy writer audit:
4 coin-mutation routes (match reward, pack BUY, quick-sell, market buy-now),
synthetic-seller market (no sale-credit/expiry/fee), dead grant_coins/
grant_unopened_pack, no points writer. This is the deployment gate: no proxied
Python route may touch Core-owned state before R1.
Advance openfut-core gitlink to c8269d0, which adds services::economy::purchase_item
(atomic debit + mint) — the generic Core primitive the FIFA17 synthetic-seller
transfer market needs. Evidence: the Python economy audit proved market buy-now
mints a new item with no real counterparty, so debit+mint (not two-party transfer)
is the correct generic model. Core matrix + clippy green.
Advance the openfut-core gitlink 3084a46 -> ee2caa0. This does two things:
1. Reconciliation: moves the canonical Core lineage onto the committed,
validated migration trunk (66c88fb: game-scoped opaque extension,
inventory service, squad-ext routes, content-pack loader, generic
transactional profile-import service). The divergent local Core refactor
that was dirtying the eab522a checkout is preserved verbatim on branch
wip/core-local-development (f70cf44) for separate reconciliation; nothing
is lost.
2. Economy foundation: ee2caa0 adds services::economy, a generic atomic
profile-economy authority (currency/inventory/entitlements over the
existing durable tables, single-transaction compound ops, fail-closed).
The FIFA17 adapter economy engine sits on top of these primitives.
Core builds green; full matrix 41 lib + 111 integration + 16 = all pass;
clippy clean.
Adds openfut-adapter-fifa17 fut::economy — the single-writer FIFA 17 economy engine
the eventual cluster cutover needs: coins + unopened-pack entitlements + owned
inventory + stable item ids, with all-or-nothing transactional mutations faithfully
ported from the Python oracle's fut_store.Store primitives.
Atomic ops: debit (fail-closed), credit, grant_pack/consume_pack (consume-once),
allocate_item_id (unique/monotonic), add_item, and composed transactions buy_pack,
open_pack, quick_sell, market_buy_now, grant_reward. Fail-closed everywhere; the
65534 sentinel can never be bought/granted/opened (defense at the grant primitive,
mirroring grant_unopened_pack rejecting non-catalogue ids). from_fut_profile importer
round-trips coins/unopenedPackIds/items/nextItemId and floors nextItemId past the
highest existing id so re-import cannot mint a duplicate. 10 unit tests (atomicity,
sentinel safety, consume-once, quick-sell, item-id uniqueness, import round-trip).
NOT wired (R3): the live coin balance is one indivisible writer set spanning Store
BUY, pack-open, quick-sell, match rewards AND the transfer market, all in
fut_profile.json; and the generic home (OpenFUT Core) is a preserved-dirty/frozen
submodule. So a safe single-writer cutover cannot be wired yet — this engine +
importer is the coherent prerequisite. No dual-write introduced. No deployment.
Adds openfut-adapter-fifa17 fut::store_catalog — a pure, faithful Rust port of the
Python oracle's PACK_CATALOG + _pack_body + store_catalog assembly at production
flag defaults (FUT_STORE_DISPLAYGROUP=1, GROUPID=0, PRICE_PROBE=0):
- PackDef + PACK_CATALOG (ids 1/5/6/7/70; economy numbers are OpenFUT PLACEHOLDER,
wire shape is oracle-verified; 65534 deliberately absent).
- pack_body() (_pack_body port), sentinel_body() (id-65534 compatibility shim),
build_purchasegroup(unopened_ids, StoreMode) mirroring store_catalog(3627).
- Differential parity: fixtures generated from the Python oracle
(tests/fixtures/purchasegroup_{zero_sentinel,zero_clean,pack70}.json); Rust output
matches semantically (6 tests). Adapter 140 tests, host 24, fmt/clippy clean,
Python A-R oracle green.
PURE wire shaping — NOT wired into the live host. Serving purchasegroup from Rust
requires an authoritative Rust owner of unopenedPackIds, which is blocked on the
economy-authority prerequisite (R3): coins are one shared balance written by many
Python-oracle routes (BUY spend, quick-sell credit, SBC/match/objective rewards)
persisted to fut_profile.json, so no single coin-touching route can move without a
whole-cluster migration. No dual-write introduced; no production deployment.
openfut-utas-host now classifies and owns three routes, wiring the landed
adapter store_session state machine while keeping the Store economy Python's:
- POST /ut/auth: proxy to Python (which mints X-UT-SID, adopts persona, refreshes
save), OBSERVE the returned sid, and open a Rust session bound to peer IP +
configured persona. Account/economy authority stays Python.
- POST /openfut/fifa17/capability: Rust-owned, no proxy — validate + register into
SessionStore (bound/pending/ignored-late); fail-closed 400 on unsupported.
- GET .../store/purchasegroup: proxy to Python for the authoritative economy body,
then overlay ONLY the empty-My-Packs topology from the frozen session mode —
strip the 65534 sentinel for a verified clean-v1 SID, keep it otherwise. Rust
never writes economy state.
Session state (Arc<Mutex<SessionStore>> + monotonic clock) lives on Server; new()
and from_config() initialise it (signatures unchanged). handle() gains a peer-IP
variant (handle_with_ip) threaded from handle_conn. Strict never-both routing is
preserved. Pure helpers (observe_sid, parse_capability_request, overlay_empty_mypacks)
+ classifier are unit-tested; adapter+host tests + Python A-R oracle all pass.
STOP-GATE: Store BUY / coins / unopenedPackIds NOT migrated — Rust has no
authoritative FIFA17 economy-mutation path (Python fut_profile.json is the source;
Core's economy is separate/unwired), so moving BUY would split store authority.
That cluster migration is the remaining R2 gap. No production deployment.
