 ### Immediate Next Steps
 
 1. After Seth's next reboot: `ssh mac 'mount | grep auto_smb'` must show the `/Volumes/tank` trigger. If `/Volumes/tank` vanished (boot-time /Volumes cleanup), switch the map to `/tank` via `/etc/synthetic.conf` (`tank` bare line) — needs another reboot.
-2. Seth: drag `/Volumes/tank` to Finder Favorites (checklist). Ask whether the folder-not-drive result is acceptable or he wants the Locations icon (then: Finder Connect-to-Server + Login Item, documented as rejected-for-now in DECISIONS).

 ### Potential Gotchas
 
+- `/Volumes` has the `UF_HIDDEN` flag on every Mac — Finder never shows it when browsing Macintosh HD, and `/System/Volumes` (APFS Data/Preboot/VM) is unrelated. Seth hit exactly this ("I don't even see a /Volumes folder"). Path in: Cmd+Shift+G -> `/Volumes/tank`; in kitty `ls /Volumes/tank`.
+- `open /Volumes/tank` over ssh returned success but no Finder window appeared for Seth. Don't use `open` from ssh as a "show it to Seth" signal; tell him the path instead.
 - The Ableton Live 12 Trial Installer DMG was mounted at `/Volumes/Ableton Live 12 Trial Installer` during this session — Seth is mid-install; don't unmount/eject volumes wholesale.
 - `mount | grep tank` shows TWO lines (autofs trigger + smbfs) when mounted; only the trigger when idle. Both are normal.
 - `sed -i ""` (BSD form) is what works on the Mac even with GNU sed on PATH via gnubin — check `which sed` before scripting sed there.

-- [ ] Finder > Go > Go to Folder > `/Volumes/tank` (this triggers the mount), then drag the `tank` folder from the path bar / window title into the sidebar **Favorites**. It will NOT appear under Locations as a drive: macOS marks every automounted share `nobrowse` (documented in `man auto_master`) — the Favorite is the one-click entry, and the share mounts on first click and unmounts when idle, so leaving the LAN never hangs Finder or throws login dialogs.
