Round 185

Round UUID: b057285f-e84f-45bd-95b7-0ec59058a035

Prompt:

Classify each reef as either 'Healthy' or 'Stressed' using these explicit, threshold-based rules. Follow the instructions exactly, as written. Use ALL available features, and only those marked as decisive in the rules. Prioritize unambiguous application of rules. 

A. Assign 'Stressed' if ANY ONE of the following applies:
    1. At least TWO of these are true:
        • AlgalCoverage is 'Extensive' or 'Heavy'
        • BleachingEventsPerYear is 'Constant' or 'Frequent'
        • BiodiversityIndex is 'Low'
        • PreviousStressIncidents is 'Moderate' or worse
        • PollutionLevel is 'High' or 'Critical'
        • DistantStressIndicators is 'Confirmed'
        • PredatorActivityLevel is 'Severe' or 'Catastrophic'
        • ReefIntegrityScore is 'Poor' or 'Very Poor'
    2. At least THREE of these are true:
        • PreviousStressIncidents is not 'None'
        • DistantStressIndicators not 'None'
        • NearbyHealthyReef is 'Absent'
        • PredatorActivityLevel is 'High' or worse
        • PollutionLevel is 'High' or worse'
    3. ReefIntegrityScore is 'Very Poor' AND PollutionLevel is 'Critical'
    4. ObservationDuration > 100 AND (BleachingEventsPerYear is 'Constant' or 'Frequent')

B. Assign 'Healthy' if ALL of the following are true:
    1. AlgalCoverage is 'Minimal', 'Sparse', or 'Moderate'
    2. BiodiversityIndex is 'High' or 'Very High'
    3. ReefIntegrityScore is at least 'Moderate'
    4. BleachingEventsPerYear is not 'Constant' or 'Frequent', UNLESS both PollutionLevel is 'Low' or 'Moderate' AND PreviousStressIncidents is 'None' or 'Minor' AND BiodiversityIndex is 'High' or 'Very High' (all must be true for exception)
    5. PreviousStressIncidents is 'None' or 'Minor'
    6. PollutionLevel is 'Low' or 'Moderate'

C. In all other cases, assign:
    • 'Stressed' if two or more negative signals among: PreviousStressIncidents not 'None', DistantStressIndicators not 'None', NearbyHealthyReef 'Absent', PredatorActivityLevel 'High' or worse, PollutionLevel 'High' or worse, BiodiversityIndex 'Medium' or lower
    • 'Healthy' otherwise

Numerical variables:
    - ObservationDuration > 100 only used with stress factors; not decisive alone.
    - ReefAverageAge, CoralAgeEstimate, AcousticIntensity are not decisive alone.

If in doubt, and absent contradictory signals, favor 'Healthy' where positive indicators strongly dominate.
