- supercall before/after: 不设 skip_origin，两路径均执行原始 brk，消除时序差异 - 新增 before_compat/after_compat: hook compat 32位表 nr45，对齐时间开销 - 防止 Hunter 等检测工具通过 64/32 位表时序差异识别 KernelPatch
- supercall.c: 新增 supercall_wrapper/supercall_slow_path/supercall_compat_wrapper 用 fp_hook() 直接替换 sys_call_table[45]，绕过 fp_hook_wrap transit 框架开销 out-of-range cmd: tail-call 原始函数(零开销) in-range cmd + 非特权进程: uid 预检查后 tail-call(极小开销) #ifdef ANTI_SIDECHANNEL_V4 条件编译，可回退到 v3 - syscall.h: 新增 extern uintptr_t *sys_call_table/compat_sys_call_table 声明
问题：supercall_wrapper的uid预检查把APatch Manager的合法key验证请求也拦截了， 因为APatch Manager是普通app uid，不是root也不在su允许列表。 修复：in-range cmd直接进慢路径做key验证，不做uid预检查。
方案F的快速路径(out-of-range tail-call零开销)导致in/out ratio≈1.45被Hunter检测。 F2方案：所有cmd都走slow_path统一做strncpy+auth，消除in/out时间差异。 同时compat表也做统一路径对齐。 预期ratio→~1.0。
…+execve fp_hook+KPM callback(G7)+trampoline bug fix
当 su_path 改为 /system/bin/cu 时，/system/bin/su 仍然可用。 确保第三方 root 应用（RE、MT 管理器等）不受影响。 实现：IS_SU_PATH 宏同时匹配 current_su_path 和 LEGACY_SU_PATH(/system/bin/su) 覆盖 3 处匹配点：handle_before_execve、su_handler_arg1_ufilename_before、 sucompat_check_and_replace_path
