waynergy does not appear to respect the xkb_keymap, fails to send modifier keys

Problem Statement:

I'm trying to migrate from a functioning barrier setup to a waynergy/barrier hybrid. Initially I ran into some offset issues, and was able to set my client configuration to:

xkb_key_offset = 7

[log]
level = 4
mode = a

This corrected everything but the control keys (LWIN, ALT; but SHIFT was fine). I saw the documentation about the xkb_keymap for mac, and attempted to install that at .config/xkb/keycodes/mac and .xkb/keycodes/mac since I saw both mentioned in other issues (#3, #4, and some others); I also placed the recommended xkb_keymap file next to the config.ini file. I know that that file is being seen by waynergy because if I place a syntax error in it, it causes a startup failure. The file is:

xkb_keymap {
  xkb_keycodes { include "mac+aliases(qwerty)" };
  xkb_types  { include "complete" };
  xkb_compat { include "complete" };
  xkb_symbols { include "pc+us+inet(evdev)+capslock(super)+compose(ralt)" };
  xkb_geometry { include "pc(pc105)" };
};

And as mentioned the mac keymap is copied verbatim in both places.

When starting waynergy, the below log plays, and this section (less some extraneous journal stuff):

[INFO] Using wlroots virtual input protocols
[INFO] Using wlroots protocols for virtual input
[DEBUG] Will default to map xkb_keymap {
xkb_keycodes "(unnamed)" {
# snip the full printout of what I believe to be the default 'builtin' xkb map that is _not_ the `mac` keymap
}
[DEBUG] Property xkb_keymap not found in INI
[DEBUG] Setting virtual keymap
[DEBUG] max key: 135

This appears to indicate it is not reading the mac keycode file; though it must be doing something with it because, again, a syntax error results in waynergy not starting.

Reading the output from the log as it runs, I can see waynergy receiving the correct keycode and offsetting it correctly:

[DEBUG] Keycode: 63, state 1
[DEBUG] Key 56 remapped to 63
[DEBUG] Modifiers: depressed: 0 latched: 0 locked: 0 group: 0

Reading the mac keycode list, this should map to LWIN, but in the default it's using, LWIN is mapped to (taken from the snipped section where it prints out the default keymap):

<LWIN>               = 133;

I had thought this might be a 'weird things happen when reading from a symlink', which NixOS uses thoroughly in this case, but I replaced the files with 'real' files in the same location (not symlinks) with the same content to no avail.

I've also tried doing some raw keymap to map 63 -> 133, (I tried both directions, mostly out of desperation), but no dice.

I also briefly tried switching to uinput, but getting that to work on NixOS seems to take a little more magic than I had left after staring at keycode logs for longer than was medically advisable.

I looked a bit over the code around config reading to see if there were clues, but my C is quite weak; so I didn't see anything that stuck out, and tbh it's far more likely that this is an error on my end, but I'd appreciate any pointers you could give in the direction of a solution -- every other key seems to work alright (ironically, the only key that isn't working is the most important key in hyprland. 😦)

Log attached below, lmk if you need more data, appreciate any help.
