+      **Round 5 was itself run and failed (2026-07-14); this entry now covers
+      round 6.** Two of the four reports were never actually testing the fix:
+      both watchers are Hyprland `exec-once`, so `nomarchy-home` swaps the
+      config but leaves the *old* processes running — only `nomarchy-dock-audio`
+      (a user service) had picked up new code. **Relogin is mandatory before
+      testing either watcher**; confirm with `tr '\0' '\n' < /proc/$(pgrep -f
+      bin/nomarchy-display-profile-watch)/cmdline | sed -n 2p` and grep the
+      script for `outputs-changed`. The other two were real and are fixed in
+      the commit carrying this entry: automatic dock mode did not exist at all
+      (the watcher auto-*undocked* but only ever matched display profiles on
+      plug, and this box has none saved with `displayProfileAuto` unset, so
+      nothing happened — `Dock mode` was interactive-only), and the BenQ's
+      audio was unreachable because WirePlumber had `alsa_card.pci-0000_c3_00.1`
+      pinned to `pro-audio`, whose raw `pro-output-N` sinks have no ports and
+      no routing. The BenQ's own USB card is input-only (all profiles
+      `sinks: 0`), so DisplayPort is the only path to its speakers.
+      **Also check:** no display profile is saved, yet plugging the BenQ must
+      now dock by itself; and `journalctl --user -t nomarchy-dock-audio` shows
+      `repaired-card=alsa_card.pci-0000_c3_00.1 profile=HiFi` on the first
+      plug, after which audio reaches the monitor's speakers. A saved+matching
+      display profile must still win over auto-dock.

       updating to the commit carrying this entry, run `nomarchy-home` and
       relogin. With the lid open, put visible windows on at least workspaces
