keymatrix - which endpoint actually receives a chord, given how you are connected.
The keyboard slice of semester/peripheral-matrix, sharing its vocabulary. Not a

Chords are declared in four incompatible places across this fleet -- GNOME dconf
(configured by hand through a GUI, documented only as prose), AHK inline in .ahk
files, AutoKey per-item JSON, espanso YAML -- with no single source of truth and
drift already present. The harder half is that a chord's destination depends on
POSTURE: with the peripherals on nrft you VNC out to Windows and GNOME eats
first; with them on ethbox you RDP back into nrft and the arbitration inverts.

render recipes and CSV rows, never applied
**There is no apply verb.** Not a disabled one, not one behind a flag. The
owner's standing rule is that nrft is managed by hand: report recipes, do not
apply them. A tool that cannot write cannot write the wrong thing.

One normal form for a chord, and a parser/emitter per dialect.
Four systems in this fleet declare chords, and no two spell them alike:
GNOME dconf <Control><Super>c <Primary><Alt>1 <Super>Page_Up

AutoKey ["<ctrl>","<super>"] + "w"
keyd leftcontrol+leftshift+f11 -> M-f11
A normal form is not tidiness here; it is the only way to ask whether two
declarations are the same chord. GNOME's own output is not internally
consistent -- `<Control><Super>c` and `<Super><Control>1` are both live in the
same session -- so even comparing GNOME to GNOME needs one.

modelgen's `GENERATORS` is a dict of twelve names to nine *classes*, all

for csv, zipfile, lzma, bz2, xml and ast -- the ODS extractor's machinery --

module's docstring states, and it breaks it at the registry rather than
inside a cmd_*, which is why moving one import does not fix it.
The shape that works is a name -> **import path** map resolved on use,
instead of a name -> **class** dict resolved on import. `Profile.available()`

globbing files and importing nothing to say what exists.

"""
Which endpoint actually receives a chord, given how you are connected.
The fleet has two POSTURES, and the direction of remote control flips between
them. That is the whole reason this module exists: a chord's destination is not
a property of the chord.
A peripherals on nrft nrft (GNOME/Wayland) --RealVNC--> ethbox (Windows)
and on to aws-workspace, three hops
B peripherals on ethbox ethbox (Windows) --RDP--> nrft (headless GNOME)
aws-workspace direct from ethbox, two hops
In A, GNOME arbitrates first and AHK's bindings are the unreachable ones. In B
that inverts exactly. `vnc-keyboard-routing.md`'s table is posture-A-only, and
reading it as general is how a fix gets designed for half the fleet.
## The rule
A chord reaches the far side unless the near side takes it first. Who "the near
side" is, is the posture. Three things decide the outcome, in order:
1. the transport's own grab -- can the client bind the keyboard at all;
2. chords the client intercepts for itself, whatever the compositor thinks;
3. otherwise, whatever the near endpoint has declared.
Step 3 consults **observed** state, never the keymap. The near side shadows with
chords nobody wrote down -- `<Super>l`, `<Alt><Super>8`, `<Super><Control>1..9`.
A rule that only knew about declared actions would miss all of them, and those
are the ones that surprise you.
## Nothing about a specific chord is hardcoded here
`Ctrl+Super+Left/Right` passes because it is *absent from the observed set*,
verified across all five keybinding schemas -- not because a constant says so.
Every transport-specific fact is data with an `evidence` string, so a claim can
be checked against the note it came from.
