The interactive planning TUI never reports its claude session id back, so
planning_session_id stayed NULL and UpdatePlanningSessionIdAsync had no caller
at all -- ResumeAsync always threw "No Claude session ID captured yet".
Resume now looks the id up in the transcript Claude Code writes to
~/.claude/projects/<encoded cwd>/<sessionId>.jsonl for the planning worktree
(newest file wins; a worktree hosts exactly one session) and persists it, so
the next resume is a plain DB read. No transcript -> a clear "cannot resume"
instead of resuming the wrong session.
