 `board` now checks the pane's process instead of trusting the name. What is still missing is a
 single command that repairs this project after a reboot without a person looking at each pane —
 `board` is that command now, and it does rebuild, but nothing runs it automatically.

+## Done: git is a gate, a tab and a warning — 2026-11-12
+
+Researched first: Paperclip has no CLI git commands, does not check that a project folder is a
+repository, and has no hook for `git init`. What it does have is a git scan of every execution
+workspace (`GET /api/execution-workspaces/{id}/close-readiness` → `git{}`), which is the only
+place branch, dirtiness, distance behind the base and merged-ness are known. Its web screen
+("Git status", "Source control") is per task worktree, not per project folder.
+
+So the three pieces were built round that:
+
+- **the gate** in `bin/office`: Y makes the repository and a `.gitignore` containing
+  `.paperclip/`, stages everything and stops before committing; N creates a `local_path`
+  project; `--commit-all` does both. Nothing ever commits on the person's behalf.
+- **the `git` tab** in `Project>project`: this folder read with git, then Paperclip's scan of each
+  worktree. `t` opens lazygit, which is also what edits `.gitignore` (files panel `i`).
+- **the warning line** in every pane while the folder cannot hold a worktree. One line, drawn once
+  per screen by a wrapper model, taking the title line rather than the key hints.
+
+Two bugs were found and fixed on the way: a bare `4` meaning "the projects tab" (now named
+constants), and the base branch being hardcoded to `main`, which would have broken every project
+on a repository whose default branch is `master`.
+
+Still open, and now visible in the git tab rather than invisible:
+
+- a project's worktree policy cannot be changed after creation, so a `local_path` project stays
+  that way; the tab says so plainly but offers no conversion.
+- the banner is read once at pane start; a folder fixed in another pane keeps its warning until
+  `R`.
