"""Unit tests for the FUT match core loop — PURE, no server, no state, no profile.

Why separate from test_fut_contract.py: that suite is read-only by design (it hits
a live server and must never mutate the save), but the match loop credits coins and
bumps the W/D/L record. So the two pure pieces — result detection and the reward
body — are tested here instead of making the HTTP suite stateful.

Guards the two things that would silently break the loop:
  * `_match_result()` mis-reading a scoreline (wrong result -> wrong payout)
  * `destroy_match_body()` drifting from FutDestroyMatchServerResponse
    (deser 0x180121b60): a non-scalar there is the freeze class at 0x1801c7f1a,
    and a renamed key is silently SKIP'd, i.e. the reward vanishes with no error.

Run:  python3 tools/test_match_rewards.py     (exit 0 = pass)
