+**full request body** via `_inv_read_frame`: `[AFI] | mask_len(bits) | mask value | first_block |
+count-1`, with the inventory flags set by `iso15_frame(inventory=…, afi=…)`. Mask-less (default),
+mask-based selective anticollision, and AFI filter all supported. **15693 is now datasheet-complete

 **Hardware verify pending:** SLIX2 catalog was verified only against unit tests + a live-session
 drive (no SLIX2 tag on the reader). Confirm on a real SLIX2 when one is available.
