Port the PROVEN empty-"My Packs" resolver crash-guard into the canonical
autopatch.py /proc-mem patcher. When no `mypacks` purchase group exists, a
fresh FIFA 17 client resolves category id -1; CardsDLL FUN_1800147f0 at RVA
0x14858 (`JNZ 0x14869`, bytes 75 0f) treats every non-zero category as
resolvable, calls FUN_180014420, gets NULL, and dereferences [NULL+0x48] at
0x180014882 (0xC0000005). Rewriting JNZ->JG (7f 0f) preserves positive-category
resolution (EDI>0) while routing zero/negative categories to the existing
Browse/list-all path -> no NULL lookup, no crash, Store opens on Browse Packs.
- STORE_PATCHES_GUARDED table pins RVA 0x180014858 orig 75 0f -> patch 7f 0f.
- Applied every tick, fail-closed via guarded_action(): apply only when the
live bytes are the known original; no-op when already patched; SKIP+log an
unrecognised CardsDLL build (never blindly overwritten).
- Runtime watch loop moved under `if __name__ == "__main__"` so the module
imports cleanly for unit testing; script behavior is unchanged. Existing
ProtoSSL cert-gate and STORE_PATCHES enforcement are byte-identical (indent
only).
- test_autopatch_guard.py: pure test covering PATCH/NOOP/SKIP and pinning the
exact guarded RVA/bytes.
Proven on the tested build (CardsDLL 4706a881...) by a clean fresh-process
no-sentinel A/B (R1). Dormant while the backend active-sentinel is present.
