Description

In the web UI, a project/worktree can have existing sessions returned by the API, but the sidebar renders only New session and Load more. Clicking Load more makes a request, but no session rows appear. The list endpoint was returning session records for the project, but the sidebar stayed empty.

Root cause appears to be Session.list() / listByProject() ignoring the explicit directory filter when experimental workspaces are enabled:

} else if (input.scope !== "project" && !input.experimentalWorkspaces) {
  if (input.directory) {
    conditions.push(eq(SessionTable.directory, input.directory))
  }
}

With experimental workspaces on, GET /session?directory=...&roots=true&limit=... can return project-wide sessions instead of sessions for the requested directory. The web sidebar then client-filters by exact session.directory, so if the loaded page contains sessions from other worktrees/directories, the visible list is empty while sessionTotal still makes Load more appear.
