Root Cause: check-risk endpoint passes blockReason='SMART_VALIDATION_QUEUED'
but addSignal() only accepted 'QUALITY_SCORE_TOO_LOW' → signals blocked but never queued
Impact: Quality 85 LONG signal at 08:40:03 saved to database but never monitored
User missed validation opportunity when price moved favorably
Fix: Accept both blockReason variants in addSignal() validation check
Evidence:
- Database record cmj41pdqu0101pf07mith5s4c has blockReason='SMART_VALIDATION_QUEUED'
- No logs showing addSignal() execution (would log '⏰ Smart validation queued')
- check-risk code line 451 passes 'SMART_VALIDATION_QUEUED'
- addSignal() line 76 rejected signals != 'QUALITY_SCORE_TOO_LOW'
Result: Quality 50-89 signals will now be properly queued for validation
