Adds two staging-only harnesses and records the results. scripts/fifa17-discard-validate.py drives the REAL Rust/Core quick-sell path for a fixture spanning every quick-sell-relevant category, and checks each against the authoritative table value emitted by the discard_matrix example (i.e. the shipped implementation, not a reimplementation). Per item it asserts the payout is exact, the instance is removed exactly once, and a REPLAY of the same request grants nothing and resurrects nothing. Results with OPENFUT_FIFA17_DISCARD_TABLE=1 on the real 1993-item club: players 6/6 exact 752 .. 74,400 (rareflag 1,3,4,5,6,11,21,22,23,24) staff 2/2 exact 36 (gk coach, fitness coach) consumables 4/4 exact 3, 3, 32, 38 club item 1/1 exact 0 (kit -- and 0 is what the client displays) TOTAL 12/12 exact, 0 replay grants wire discardValue == expected == actual payout for every player, so what the client is shown and what Core credits are the same number by construction. Concurrency: 4 simultaneous DELETEs on one wire id -> removed exactly 1, paid exactly once (23,280). scripts/fifa17-restart-persistence.py restarts Core and host IN PLACE with their own environment rather than via the bring-up script, because `up` re-seeds the club and would mask a persistence failure. It refuses to signal any process outside the staging root -- production runs as another user and is skipped explicitly. Result across SIGTERM + respawn of both: coins 29,967,428, owned 1978, players 1958 -> PERSISTED EXACTLY. Production untouched; staging only, flag set only in staging.
