Replace stub_return_zero with a canary-faithful implementation that returns bit `priv` of the loaded XEX's XEX_HEADER_SYSTEM_FLAGS (key 0x00030000) bitmap. Mirrors xenia-canary xboxkrnl_modules.cc:22-39: `(flags >> priv) & 1` for priv < 32, else 0. Plumbing: - xenia-xex: header_keys::SYSTEM_FLAGS const + get_system_flags() accessor. - xenia-kernel/state.rs: pub xex_system_flags: u32 + xex_priv_logged HashSet for one-shot per-priv tracing. - xenia-app: kernel.xex_system_flags wired in cmd_exec_inner. - xenia-kernel/exports.rs: real export body + unit test covering bits 10/11/0/64 + zero-flags case. Sylpheed's bitmap is 0x00000400 (only XEX_SYSTEM_PAL50_INCOMPATIBLE, bit 10). At -n 500M with the fix: - XGetAVPack: 0 -> 1 (priv-10 gate at lr=0x824ab598 flipped). - 10 other canary-only exports + 9 producer PCs + 3 parked handles unchanged. Priv-11 site at sub_824A9710 is downstream and still not reached — AV/crypto block aborts after XGetAVPack returns our placeholder 0x16 (canary returns 8/HDMI; Sylpheed accepts only 3/4/6/8 per xenia-canary xam_info.cc:250-251). Tests 588 -> 589. Lockstep deterministic (3 reruns identical): n50m goes 50000008 -> 50000005 instr / 407415 -> 407417 imp / swaps=2 / draws=0. Goldens re-baselined (sylpheed_n50m, sylpheed_n2m); oracle test green. Full chain-of-effects + next-frontier hand-off in audit-findings.md under KRNBUG-XEX-001.
