The gap

I ran a plain git switch v0.20.0 in a linked worktree that madt_worktrees action=add created for a scratch repo outside the session's directory. The local-git hook denied it with "Moving the PRIMARY checkout of a foreign repo is not allowed". The target was a linked worktree, not a primary. I have not checked why the hook classified it as a primary.

Repro

A scratch repo outside the session directory, with a linked worktree made by madt_worktrees action=add dir=<repo> path=.worktrees/wt branch=wt.
In Bash: cd <repo>/.worktrees/wt && git switch <tag>.
The hook denies it with the foreign-primary text.

What I want

The hook treats a linked worktree of a foreign repo as a linked worktree, as ADR 0019 says.

Acceptance criteria

The cause is found and stated on this issue.
A hook test covers a raw switch in a foreign linked worktree.
