Prompt:
Classify each reef as either 'Healthy' or 'Stressed' using these explicit, multi-factor rules:
A. Assign the label 'Stressed' if any ONE of the following apply:
1. BOTH AlgalCoverage is 'Extensive' or 'Heavy', AND BleachingEventsPerYear is 'Constant' or 'Frequent'.
2. ReefIntegrityScore is 'Very Poor' AND PollutionLevel is 'High' or 'Critical'.
3. ObservationDuration > 100 AND BleachingEventsPerYear is 'Constant' or 'Frequent'.
4. At least TWO of these:
a) PreviousStressIncidents is 'Moderate' or worse
b) DistantStressIndicators is 'Confirmed'
c) PollutionLevel is 'Critical'
d) BiodiversityIndex is 'Low'
e) PredatorActivityLevel is 'Severe' or 'Catastrophic'
B. Assign the label 'Healthy' only if ALL the following are true:
1. AlgalCoverage is 'Minimal', 'Sparse', or 'Moderate'.
2. BiodiversityIndex is 'High' or 'Very High'.
3. ReefIntegrityScore is at least 'Moderate' (i.e., not 'Poor' or 'Very Poor').
4. BleachingEventsPerYear is not 'Constant' or 'Frequent'.
5. PreviousStressIncidents is 'None' or 'Minor'.
C. If neither A nor B apply, then:
- If there are at least THREE negative signals among: PreviousStressIncidents not 'None', DistantStressIndicators not 'None', NearbyHealthyReef is 'Absent', PredatorActivityLevel is 'High' or worse, PollutionLevel is 'High' or worse, assign 'Stressed'.
- Otherwise, assign 'Healthy'.
For numeric variables:
- ObservationDuration > 100 signals concern only if combined with stress (see A3).
- ReefAverageAge and CoralAgeEstimate are not independently decisive.
- AcousticIntensity is ignored unless specified in the rules above.
Apply the rules exactly as written, giving priority to multi-factor combinations indicating stress. If uncertain, err on the side of 'Stressed.'
