Unit tests cover classification and body parsing; they do not prove the running
host behaves. These three scripts exercise the real service, and they found
nothing broken but make the two load-bearing claims checkable:
fifa17-apply-snapshot.py Core truth around an apply: coins, owned rows, kind
histogram, the source stack's copy count, and the
target's mutable fields (contract/fitness/playStyle/
training/injury). Coins and ownership come from the
staging DB, not the wire, so the check cannot be
satisfied by a projection bug.
fifa17-apply-probe-smoke.py Replays the EXACT captured request plus the edges,
against the live host, no client needed:
1. {"apply":[{"id":100000003}]} -> 200 {"itemData":[]}
source=Consumable subtype=201 copies=1,
target=fifa17_200389 rating=87
2. two targets -> 400 apply_batch_unsupported
3. unknown target wire id -> 200 UNRESOLVED_WIRE_ID
4. unowned source -> 200 NOT_OWNED
then re-snapshots: Core identical after all four.
fifa17-apply-gate-off.py The production-safety claim. With APPLY_PROBE unset
the same request must produce the pre-probe
behaviour, and does: no apply-probe line, three
passthrough lines, 502 into the dead upstream, Core
unchanged. Verified by restarting staging without the
flag -- an assertion about failing closed is worth
nothing unless the closed path is executed.
Nothing here writes to production; snapshot reads the staging DB read-only.
