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.
