One pane that asks, a grid of six, drag a title to move a pane - #72
Conversation
An office no longer opens a fixed layout. It opens ONE pane whose menu asks what it should be: any OFFICE_AGENTS entry, a shell, or the file editor. Ctrl-Space n asks the same for every pane after it. Panes sit in a grid of at most three across and two down, rebuilt on every add, park, move and close. - parked panes are listed first in that menu, each under a letter, and the bar counts them, so a parked pane can always be found again - drag a pane's title onto another pane to move it there; border drag no longer resizes (tmux reports a divider press as the same event) - the first agent works in the checkout, every later one in its own worktree - removed: the right strip, the s/e/c/a toggles, | - C, the chat pane and OFFICE_CHAT_*, OFFICE_STRIP_WIDTH, OFFICE_DEFAULT_DESKS - bin/grid-probe replaces bin/zoom-probe; bin/menu-probe drives the menu on a real client; bin/mouse-probe covers the title drag Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- pane-exited joins after-kill-pane: `exit` in a shell closes the pane without a kill, and left its neighbour twice as wide - Ctrl-Space x on the "what should this pane be?" pane does nothing - the retired verbs (chat, shell, edit, sessions, layout) say they are gone instead of being fuzzy-matched as a repo name - office help no longer lists an `edit` command the package never shipped Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
README, GETTING-STARTED, CONTRIBUTING and the product page describe the one-pane start, the six-pane grid and the five pane actions. The chat pane and the "talk to the agent you built" pitch are gone; your own chat is one more OFFICE_AGENTS entry. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Use a one-based SGR row for the title click.
#{pane_top} is zero-based. SGR mouse rows are one-based. The top-row panes therefore receive row 0, which does not target their title line. The title drag cannot reorder pane 1, so mouse-probe fails.

Ubuntu CI (tmux 3.4) failed mouse-probe: the title drag opened copy mode and moved nothing. Measured on 3.4, 3.5a and 3.6b: a press on a title sends no event, and the drag arrives as a plain MouseDrag1Pane with no coordinates, which a fast drag out of a pane body also sends. There is no safe way to tell the two apart there, so the probe skips the move checks below 3.7 and the bar only shows the hint where it works.

Three panes were A|B|C and four were columns (A C / B D). The grid now reads like a page: two panes share a row, a third goes underneath, the fourth beside it, and five and six are 3 on top, 2 or 3 below. Pane numbers follow the same order. grid-probe checks rows per count. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The zoom step targeted the pane the exit check had just ended, so tmux printed "can't find pane", nothing was zoomed, and "a zoomed office comes back as a grid" passed on nothing. It now zooms a live pane and checks the zoom took first. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
On the Ubuntu CI runner the pane saw the session attached and called display-menu a moment before the client took commands. tmux answered "no current client", no list drew, and the pane waited for a key with nothing on screen. Logged in a debug CI run. office new now returns the menu's status, and _office_wait retries a refused menu for two seconds. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
This reverts commit fc111cd.
Ubuntu CI failed menu-probe on every run. Logged in a debug CI run: the first pane's zsh -ic starts about 8s after the attach on that runner, and the probe waited exactly 8s, so it typed 1 before the menu drew and every step after was off by one. Reproduced in Ubuntu 24.04 with a 9s shell start: the old probe fails the same four checks, this one passes. It now waits for the menu's title and for each pane change, up to 60s, and takes 2-3s on a fast machine instead of 35. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The real cause of the Ubuntu menu-probe failure, found by printing what the client drew: /etc/zsh/zshrc runs compinit, which on the GitHub runner stops at "insecure directories ... abort compinit [n]?". The pane waited on that question and the probe's 1 answered it. The 8-second shell start named in c2d606a was that prompt waiting, not a slow shell.
