- Integrated `zupt_mac_verify_ct` in `zupt_decrypt_buffer()` to replace C XOR loop for HMAC-SHA256 - Integrated `zupt_ct_select_32` in `zupt_mlkem768_decaps()` to replace C `cmov()` for FO transformation - Added `include/zupt_jasmin.h` with extern declarations and ABI docs - Added `#ifdef ZUPT_USE_JASMIN` guards with clean C fallbacks in `zupt_crypto.c` and `zupt_mlkem.c` - Makefile now auto-detects `jasmin/*.s`, assembles and links with `-DZUPT_USE_JASMIN` Closes #3
