Read-only diagnostics

All vcli diag commands are read-only by design. They never delete locks, never close cellviews, never run a SKILL command that could mutate state. Use them when "something is wrong but I don't know what."

vcli diag cdslck <LIB>

Enumerate every .cdslck lock file under an OA library, report who holds it (owner@host:pid:start_time) and how old it is.

# All locks under FT0001A_SH
vcli diag cdslck FT0001A_SH

# Only maestro view locks
vcli diag cdslck FT0001A_SH --view maestro

Sample output:

{
  "library": "FT0001A_SH",
  "read_path": "/home/meow/projects/ft0001/FT0001A_SH",
  "count": 1,
  "locks": [
    {
      "path": "/home/meow/projects/ft0001/FT0001A_SH/INVX2/maestro/.cdslck",
      "relative": "/INVX2/maestro/.cdslck",
      "cellview": "/INVX2/maestro",
      "owner_record": "meow@eda:12345:1717820000",
      "owner": "meow",
      "host": "eda",
      "pid": 12345,
      "mtime": 1717820000,
      "age_seconds": 4237.2,
      "age_human": "1.2h"
    }
  ]
}

Workflow when a lock is held

1. Check if the holder is still alive:

   # On the lock's host (from `host` field):
   ssh <host> ps -p <pid>
   

2. If alive — the holder has the cellview open. Coordinate or wait.
3. If dead — the lock is stale. Confirm with the owner, then:

   # On the lock's host:
   ssh <host> rm <path>
   

   ⚠️ Never rm -f a live lock — it corrupts the cellview.

Implementation notes

• Resolves readPath via the named cell.read_path RPC (not raw SKILL exec), so non-admin users can run this.
• Enumerates locks with SSH find — does not go through the SKILL channel, which is precisely what you may be trying to debug.
• Batched cat + stat over one SSH round-trip, so even libraries with hundreds of locks finish in < 1 s.

Related: vcli window dismiss-dialog --x11

When a modal dialog has deadlocked the CIW, the SKILL channel itself is stuck. The X11 SSH bypass SSHes into the same host, finds the modal with xwininfo, and sends a keypress to dismiss it.

# Default: send Enter
vcli window dismiss-dialog --x11

# Cancel button
vcli window dismiss-dialog --x11 --action escape

# "No" button (for Save As / dedupe dialogs)
vcli window dismiss-dialog --x11 --action alt-n

Prerequisite: VB_REMOTE_HOST set; the Python helper is vendored in resources/x11_dismiss_dialog.py (no pip install needed) and auto-uploaded to /tmp/virtuoso_bridge/<client>/x11/. Requires python3-Xlib on the remote host.
