desk-1-home.kdl asked the Sceptre M34 for 3440x1440@239.999, a mode the panel has never offered. niri does not reject an unavailable mode: it logs "configured mode ... could not be found, falling back to preferred" and drives the EDID preferred mode - 60 Hz - on every connector event, which is why the monitor looked like it was dying rather than misconfigured. Read live with `niri msg outputs`, the mode list tops out at 180. Also destroys the copies of the phantom number: displays.md carried 239.999 in its diagram, its panel table and its copy-paste pattern block, and its rule 4 claimed an impossible mode leaves the output dark. Rule 4 now states the real failure mode, a new section separates config / DP-link / amdgpu-driver faults by log signature, and wlr-randr is corrected to not-installed (three pages claimed it; `pacman -Qs wlr` matches nothing). Applied live with `niri msg output <panel> mode <mode>` - the temporary per-output path, so no config reload and no logged-out session - verified at 3440x1440 @ 180.000 Hz with the compositor PID unchanged.
