Four failures from Bernardo's round-4 dock pass on the AMD dev box, plus a
headphone regression, tracked to three causes.
The display watcher ran socat with `-T 1`, which closes Hyprland's IPC
socket after one second of *inactivity*. A dock is normally plugged into an
idle desktop, so the socket was almost always mid-reconnect at that moment
and `monitoradded` was lost outright — and the wallpaper repaint, the
docking profile, and the dock-audio reprobe all hung off that single event.
The reconnect path recovered only the lid inhibitor, so the dock stayed
half-configured until something else poked the watcher.
Make the connection long-lived and take the periodic tick from a 1s `read`
timeout instead, then let the *output set* — not the event — decide: a new
`reconcile` diffs it and is called on both ticks and monitor events, so an
event now only makes the reaction instant rather than necessary. A newly
present external output is as unambiguous a physical plug as the event was,
so it may still override a manual sink choice. Wallpaper paints are retried
over the first few seconds because awww registers an output on its own
schedule, not the compositor's.
Hyprland calls every key-capable evdev node a "keyboard": the lid and power
buttons, a monitor's control channel, and each extra HID collection of a
real keyboard. One dock with one keyboard asked for a layout four times.
udev already draws the distinction properly, so take ID_INPUT_KEYBOARD from
it, map the names into Hyprland's spelling, and ask once per physical
keyboard — applying the answer to every node it brought with it.
Finally, a sink WirePlumber has been told to prefer is stored as the
configured default and outranks every priority rule. On UCM cards the
headphones are a sink of their own rather than a route, so once anything
pinned a sink (this feature on a dock plug, or the user in the Audio menu),
plugging headphones in could no longer take the audio back. The `watch`
loop already subscribed to exactly the right events with an empty handler;
finish it. Unplug needs no undo — the pin goes stale and WirePlumber falls
back by priority on its own, to the dock when docked and the speakers
otherwise.
Verified V2: checks.docking-ux and checks.dock-audio pass with new guards
against each regression; the keyboard filter and both sink selectors run
against the dev box's real devices and sink names. The hotplug paths need
hardware — queued as docking round 5.
Also queues #107, renaming theme.json now that it holds the system state.

Restore the old flake's external-only workspace handoff, protect closed-lid cable removal with a verified low-level logind inhibitor, and use monitor-added as the settled audio reprobe boundary.
Verified: V2 — nix flake check --no-build; docking-ux, option-docs, and template-sot checks; KVM tools/monitor-fallback.nix lifecycle test.
V3 pending: closed-lid BenQ round 4 in agent/HARDWARE-QUEUE.md.
Real dock QA exposed pointer-bound menus, an absent default rescue watcher, the unsafe zero-output panel-off path, missing keyboard/audio hotplug coverage, and unpainted new outputs.
Route Rofi to the focused output; replace panel disable with safe workspace migration; always run and reconnect the display watcher and repaint hotplugged outputs; expose a default per-device keyboard picker; handle audio card availability transitions.
Verified: V1 — nix flake check --no-build; checks.docking-ux real Home Manager artifact build; option-docs/template-sot; Nix parse, py_compile, and git diff --check. V2 unavailable: no readable KVM. V3 pending in agent/HARDWARE-QUEUE.md.
Bernardo's dock test (the #87 V3): audio stayed on EasyEffects→speakers.
Root cause, established live: WirePlumber's stored default
(default-nodes state, written by any past explicit pick) outranks the
priority.session rules, so #87 alone can never move the default on a
real machine; EasyEffects 8 follows the default device (kcfg default
true, verified by watching its output links). Fix: nomarchy-dock-audio
(modules/home/dock-audio.nix, nomarchy.dockAudio.enable, default on) —
a pactl-subscribe watcher that set-default-sinks new dock-class sinks
(regex data imported from modules/nixos/dock-audio-rules.nix, single
source) with a toast, plus a startup sweep for login-while-docked that
never overrides a manual in-dock pick. Unplug falls back by priority.
Menus: Display gains docked rows — "Laptop screen off · everything →
<ext>" (live-only disable; a persisted one could black-screen an
undocked boot), "Screen on · <name>", "Move workspace · → next
monitor", "Swap workspaces" (exactly-2 gate); Audio gains a self-gated
"Send output → <dock sink>" quick row. All self-gate on real outputs.
Verified: V2-equivalent on live hardware (no dock available) — watcher
followed a fake dock-named null sink and fell back on unload, control
run without the watcher stayed pinned (proving the stored-default
diagnosis), EE output links moved mid-playback; generated menu bash -n
green, dock-row jq exercised on real pactl JSON, dispatchers probed on
live Hyprland; flake check + option-docs + template-sot green.
V3 pending: real-dock retest ×2 in HARDWARE-QUEUE (watcher keys on
new-sink events; pre-existing nodes that only flip route availability
would need the queued diagnosis data).
