- Fund Lab tab: CEF tax-arb shortlist table (char actual-vs-model, discount, 5y return/vol, scenario hits, tenders, score) built from cef_character.json + cef_annual.json. - fundlab/server_watchdog.sh: relaunches Streamlit on :8599 if the health endpoint stops answering (the old watchdog only covered the overnight screen and had exited). - fundlab/cef_universe_run.py: resumable batch extending per-share verification to all 295 CEFs -> cef_annual_all.json.
