   Thanks for the clear report. I reproduced both parts on 2.0.29, and they still happen on the latest dev (3c61484). I used the server API, so no model was needed.

   1. No repository: for a session in a plain directory, POST /api/worktree returns HTTP 400 (Worktree source not found: <dir>). On dev, the web session details menu still shows "New worktree" without checking whether the project uses git. I checked this in the code; I didn't open the web UI.
   2. Parent repository: I opened a session in parent/child while it was a plain directory, then ran git init in parent. After a worktree refresh, the plain project's worktree list shows parent. Creating a worktree from it adds a real worktree to the parent repository, and git worktree list there shows it. A directory that is already inside a repository when its session starts joins that repository's project, so there this is expected.

   The script below reproduces both parts. The cause looks like the one you describe: git.repo.discover walks up to the nearest .git, and nothing checks that the repository root it finds is the requested directory. Related: #55215 (the same "offered without a repository" problem in the TUI), PR #55326 (the TUI fix) and your PR #55771.
