Owner saw a blank /backtest — it was CORRECT (the regime gate sat out every recent session) but unexplained. Now: ?regime=0|1 override on /api/backtest, an 'apply regime gate (as deployed)' checkbox, and an empty-state message saying WHY there are no trades and what to click. Gated view = what the bot would do; ungated = the raw simple criteria. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
