Error

UnscoredBuyCandidatesError: Coverage gap: 7 of 28 buy_candidate(s) not present in predictions.json (which has 21 tickers). Missing: BIIB, LLY, ROST, SNDK, VLO, WDC, XEL. Refusing to size positions — GBM veto gate is unreachable for these tickers. Re-run predictor with --tickers to close the gap.
