+- `rdcfg-startup-push.hex`: the 114 config frames RDCfg 1.0.58 sent when it
+  started (usbmon, Wine), one `SET_FEATURE` payload per line, report id
+  first. It writes the LED block, opens a session (`02 f5 00`), writes
+  settings, then the five-profile DPI tables and button maps, the commit
+  block (`02 f1 02 ..`), and closes (`02 f5 01`). The one 64-byte line is
+  report 3.
+- `openmouse-hardware-test.json`: OpenMouse's built-in hardware test on the
+  same unit, using the local package build.

+Decoding and verification notes: `docs/redragon-m612-testing.md`.
