Round 7 FAILED: 5-6 consecutive unplugs on the dev box, the panel never came back. Round 6's retry could not have worked, because round 6's diagnosis was wrong — and so was the "phantom re-add" theory I brought to this session. With ZERO enabled outputs — panel disabled by the dock, external gone — Hyprland 0.55.4 accepts `hyprctl keyword monitor eDP-1,preferred,auto,1`, prints `ok`, exits 0, and never flushes it: the rule waits for a DRM event that is not coming. It is inert, not raced. Retrying it 25x/poll for 6 polls bought 30s of black screen and nothing else. What made this survive two rounds is worth more than the fix: every `transition=undock result=ok` in the round-6 journal was Bernardo plugging the cable back in because the screen was black. His hotplug flushed the queued rule and the next poll took the credit. Success was indistinguishable from the user working around the failure, so the logs confirmed whichever story we brought to them. Ten minutes of probing on hardware killed both. Probed live 2026-07-14 (dev box, cable out): keyword inert across 4s and 5s in two runs; `dispatch forcerendererreload` inert too; only `hyprctl reload` escapes — 99ms and 289ms. So: issue the keyword (enough whenever another output is still enabled, e.g. the menu's Dock mode), and escalate to reload only when `monitors` proves it inert. After a reload, re-assert the rule so a config that parks the panel off cannot undo the undock, and restore per-device keyboard layouts — a reload re-reads the config and drops the runtime `device[<name>]:kb_layout` an external board depends on. The menu's `enable` now proves itself against `monitors` too, instead of cheering for an exit code. Verified V3 (partial): the fixed transition driven through a real unplug — panel on, workspaces 1-3 home, 1.8s, `keyword=inert escalate=reload` -> `enable=via-reload` -> `result=ok`. V2: nix flake check --no-build; docking-ux + dock-audio; monitor-fallback.nix; shellcheck clean on display-transition. NOT proven, and queued as HARDWARE-QUEUE round 8: the watcher-driven path (exec-once + baked store path = relogin required, the round-5 trap) and repetition. The keyboard-restore path is untested — the dev box's keyboard hangs off the dock's hub, so it leaves with the cable; round 8 adds a check with a keyboard in the laptop. The VM harness still cannot reach any of this: QEMU aborts Hyprland if the last active output is deleted while the DRM output is disabled, which is the same zero-output degeneracy from the other side. New BACKLOG #114 (PROPOSED): tuigreet ignores per-device keyboard layouts — a VT has one keymap, so the greeter cannot honour `device[]:kb_layout`. Bernardo hit it logging out while docked; not a regression, a design gap. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
