Bernardo Magri 18b854563b fix(waybar): supervisor respawn + clean-restart switches; add sys-rebuild
Recovers the crashed iteration #7 (items 21+23, Latitude QA findings):

- nomarchy-waybar supervisor (waybar.nix, exec-once'd from
  hyprland.nix): any waybar exit respawns the bar; crash-loop guard
  (5 fast exits -> critical notify + stop); TERM trapped for a real
  stop. Fixes the bar-less session after a theme-switch crash.
- nomarchy-theme-sync prefers a clean `pkill -x waybar` (supervisor
  restart with fresh config+style) over the crash-prone in-place
  SIGUSR2 reload when the supervisor is running; SIGUSR2 stays as the
  unsupervised fallback.
- sys-rebuild: snapshot-first system rebuild against the CURRENT lock
  (no `nix flake update`) — the no-update twin of sys-update;
  README §3/§5 + motd list it.

Verified: V0 re-run green after crash recovery (flake check --no-build
+ py_compile); V1/V2 per the crashed session's journal entry (HM
renders exec-once=nomarchy-waybar; headless software-GL VM:
SIGKILL -> new pid, clean kill -> respawn, SIGUSR2 -> alive).
V3 pending on the Latitude (queued in HARDWARE-QUEUE.md).

# Hardware queue — V3 checks only a human can run
Everything shipped at V1/V2 whose final verification needs real hardware.
Agents **append** (newest at the bottom of a section) with exact steps;
Bernardo runs them and either checks off (`[x]` + date + verdict) or files
the failure as a NOW bug in BACKLOG.md. Machines: the **AMD dev box**
(Ryzen AI laptop: AMD + fingerprint + NPU), the **Latitude 5410** (Intel
QA machine), the **T14s** (webcam case).
## Any machine (dev box is fine)
- [ ] **Battery charge limit re-apply on unplug** — `sudo nixos-rebuild
switch` with `power.batteryChargeLimit = 80`, physically unplug/replug
AC, confirm `charge_control_end_threshold` re-reads 80. (udev trigger
already VM-verified.)
- [ ] **SSH_AUTH_SOCK for GUI clients** — after relogin, launch a GUI git
client (or `rofi`-launched terminal-less app) and confirm it reaches
gpg-agent's SSH socket without an interactive shell parent.
- [ ] **Night-light full cycle** — first menu enable rebuilds + hyprsunset
starts; later toggles are instant (no rebuild); an *off* survives
reboot (ExecCondition); stopping hyprsunset restores gamma.
- [ ] **Auto-timezone** — enable from the menu; confirm geoclue finds the
zone, `/etc/localtime` updates, and the Waybar clock refreshes
(SIGUSR2 watcher) — also after a manual `timedatectl set-timezone`.
- [ ] **Keyboard layout cycle bind** — with a comma layout (e.g.
`nomarchy.keyboard.layout = "us,de"`), SUPER+SHIFT+K cycles the
focused keyboard's layout, the Waybar `󰌌` indicator follows, and
the row shows in the SUPER+? cheatsheet.
- [ ] **Keyboard hotplug picker (re-verify after in-flake graduation)** —
plug an external keyboard post-login, pick a layout in rofi, confirm
it applies per-device only, persists in `settings.keyboard.devices`,
and graduates into a `device{}` block on the next rebuild.
- [ ] **Snapshots restore/rollback** — ⚠ PRECONDITION: update to main ≥
a47aa3a and RELOGIN first (the polkit agent starts with the session).
Bernardo's 2026-07-04 Latitude findings 5/6 ("btrfs-assistant still
crashes", "menu snapshots shows nothing") match the PRE-fix behavior
exactly: no agent → pkexec fails silently (= menu does nothing), and
a direct unprivileged run crashes (= the libbtrfsutil bug). If either
still reproduces ON THE FIXED BUILD after relogin, reopen BACKLOG
item 4 as [stuck]. Then: `nomarchy-menu snapshot` now opens
the **btrfs-assistant GUI**: a *themed* polkit prompt must appear
(hyprpolkitagent — first on-hardware outing) and the GUI must open
as root. Also exercise the fzf fallback in a terminal
(`sudo nomarchy-snapshots`): browse/diff, restore a file
(`undochange`), and a root-config rollback behind the typed-`yes`
gate. Bonus check: any other pkexec flow now prompts instead of
silently failing.
- [ ] **Update awareness** — with `nomarchy.updates.enable`, let the timer
fire (or start the unit): indicator appears only when inputs are
behind, notification only on count growth, click opens the upgrade
flow.
- [ ] **VPN menu live paths** — import a real WireGuard `.conf` and an
`.ovpn` via System → VPN, toggle up/down (● / ○ state), and the
Tailscale block: up/down + exit-node without sudo (operator grant).
- [ ] **Printer menu** — with `nomarchy.services.printing`, System →
Printers opens system-config-printer; add a printer, test page.
- [ ] **GRUB UEFI ISO theme render** — boot the ISO on UEFI hardware:
composed splash background, palette menu in the lower third, accent
timeout bar.
- [ ] **Visual theme pass** — live ISO: all six identity themes (bars) +
the four authored rofi `.rasi` (nord/retro-82/lumon/kanagawa) look
right, not just parse.
- [ ] **Auto-commit on a real machine** — System Auto-commit toggles on
(row shows state, notification fires); a theme apply from SUPER+T then
shows a `nomarchy: apply theme …` commit in `~/.nomarchy` (`git log`);
unrelated dirty files in the checkout stay uncommitted; toggle off is
itself the last commit. Also: the "Auto timezone (on/off)" row label
now reflects the real state (the `= true` comparison fix).
## AMD dev box only
- [ ] **AMD runtime bits** — VA-API (`vainfo` → radeonsi), amd-pstate EPP
active and PPD switching governors; opt-ins: ROCm (`rocminfo`, a GPU
PyTorch/Ollama smoke) and the XDNA NPU driver loading.
- [ ] **Fingerprint** — `fprintd-enroll` + (opt-in PAM) login/sudo.
## Latitude 5410 only
- [ ] **Waybar theme-switch resilience** (finding #1 re-test, needs main ≥
the supervisor commit + relogin) — switch themes repeatedly (incl.
summer-day/night whole-swaps): the bar restarts cleanly each time;
if anything kills it, it's back within ~a second. `pgrep -f
nomarchy-waybar` shows the supervisor.
- [ ] **Media keys + gestures** (from dccceb4) — volume/brightness keys
drive the OSD; touchpad gestures work.
- [ ] **v1 QA batch on-hardware pass** (583708d batch was QEMU-verified) —
general smoke before the next `main → v1` promotion.
## T14s only
- [ ] **Webcam IR-hide end-to-end on Nomarchy** — installer detects the
RGB+IR pair, bakes `hardware.camera.hideIrSensor`; `wpctl status`
shows one colour source; an app picker lists one camera; Howdy-style
direct `/dev/video2` reads still work.
