16-entry source→target table in its own flash sector (-3, magic DS5\x03),
identity default, 0xFF = disabled. Applied to the OUTGOING host report copy
only — raw interrupt_in_data (OLED screens + PS+Mute reboot combo) stays
physical. Edited via the existing 0xF6/0xF7 vendor reports with a hardened
RM+version frame (no HID-descriptor change, so Windows enumeration is
unaffected) plus a revision counter the host polls to confirm a write.
Apply logic + button set ported from SundayMoments/DS5_Bridge (credit).
scripts/remap_test.py exercises the path over /dev/hidraw without the web
tool. Verified on hardware: swap applied, read back, survived reboot.
