Prompt:
Classify each reef as "Healthy" or "Stressed" using ONLY the following explicit, threshold-based rules. Apply rules STRICTLY IN ORDER; do not interpret, interpolate, or use features not explicitly listed. Once a rule matches, assign immediately and do not check lower rules.
A. Assign "Stressed" if ANY of these are true (check in order):
A.0. STRONG PROTECTION (applies before any assignment below):
- If ALL of these are true: ReefIntegrityScore is at least "Good"; PollutionLevel is "Low" or "Moderate"; PreviousStressIncidents is "None" or "Minor"; BiodiversityIndex is "High" or "Very High"; PredatorActivityLevel is "Moderate" or lower; THEN assign "Healthy" EVEN IF any single severe negative is present (from: DistantStressIndicators "Confirmed" or worse; AlgalCoverage "Heavy"/"Extensive"; BleachingEventsPerYear any value; PollutionLevel "Critical"; CurrentFlowQuality "Poor") UNLESS at least ONE further moderate/major negative (from: AlgalCoverage, ReefIntegrityScore, PollutionLevel, BiodiversityIndex, DistantStressIndicators, BleachingEventsPerYear, PredatorActivityLevel, CurrentFlowQuality) is present beyond the single severe. If two severe/major negatives, do not apply protection – assign "Stressed".
A.1. ReefIntegrityScore is "Very Poor".
A.2. PollutionLevel is "Critical" AND at least ONE of:
- PreviousStressIncidents above "Minor"
- DistantStressIndicators is "Confirmed" or worse
- PredatorActivityLevel is "High", "Severe", or "Extreme"
- BiodiversityIndex is "Medium" or lower
- BleachingEventsPerYear is "Frequent" or "Constant"
A.3. BleachingEventsPerYear is "Constant" or "Frequent" AND at least ONE other moderate/major negative (from: AlgalCoverage "Heavy"/"Extensive", ReefIntegrityScore "Poor" or worse, PollutionLevel "High" or worse, PreviousStressIncidents above "Minor", BiodiversityIndex "Medium" or lower, PredatorActivityLevel "Severe" or worse, CurrentFlowQuality "Poor"). If PreviousStressIncidents is at least "Moderate" or BiodiversityIndex is "Medium" or PollutionLevel is "High" or worse, assign "Stressed" regardless of protection. If only one moderate negative and all other core indices are best/next-best, assign "Healthy".
A.4. BleachingEventsPerYear is "Constant" or "Frequent" AND DistantStressIndicators is "Confirmed" or worse AND at least ONE of (PollutionLevel "High" or worse; ReefIntegrityScore below "Good"; PreviousStressIncidents is not "None"; PredatorActivityLevel is "High" or worse; BiodiversityIndex is "Medium" or lower). If any two are present from this list (including BleachingEvents variable), assign "Stressed".
A.5. At least TWO of these SEVERE stress signals are present (assign regardless of protection): PreviousStressIncidents above "Minor"; DistantStressIndicators "Confirmed" or worse; PredatorActivityLevel is "High", "Severe", or "Extreme"; PollutionLevel is "High" or "Critical"; BiodiversityIndex is "Medium" or lower; CurrentFlowQuality is "Poor"; BleachingEventsPerYear is "Frequent" or "Constant"; AlgalCoverage is "Heavy" or "Extensive".
A.6. ObservationDuration > 100 AND BleachingEventsPerYear is "Constant" or "Frequent" AND at least one other moderate/major negative from above list.
A.7. If ObservationDuration > 120 AND at least THREE of (PreviousStressIncidents above "Minor", DistantStressIndicators is "Confirmed" or worse, PredatorActivityLevel is "High" or worse, PollutionLevel is "High" or worse, BiodiversityIndex is "Medium" or lower, AlgalCoverage is "Heavy" or "Extensive", ReefIntegrityScore is "Poor" or worse, CurrentFlowQuality is "Poor") AND BleachingEventsPerYear above "Rare", assign "Stressed".
A.8. (Aggregation) If at least THREE of: PreviousStressIncidents above "Minor", PredatorActivityLevel is "High" or worse, PollutionLevel is "High" or worse, BiodiversityIndex is "Medium" or lower, AlgalCoverage is "Heavy"/"Extensive", ReefIntegrityScore is "Poor" or lower, DistantStressIndicators is "Possible" or worse, CurrentFlowQuality is "Poor", and at least one is PollutionLevel is High/Critical or PredatorActivityLevel is Severe/Extreme – assign "Stressed". If only one severe indicator and all others are best/next-best, assign "Healthy".
* NOTE: Neither DistantStressIndicators (any level), Poor CurrentFlowQuality, nor AlgalCoverage Heavy/Extensive alone, or as one severe, is ever sufficient for "Stressed" if all other indices are best/next-best. Two or more such signals together DO assign "Stressed".
* SEVERE PREDATOR: PredatorActivityLevel "Catastrophic" or "Extreme" alone never triggers "Stressed" unless at least one other severe negative present.
B. Assign "Healthy" IF AND ONLY IF ALL of:
1. BiodiversityIndex is at least "Medium".
2. ReefIntegrityScore is at least "Moderate".
3. PollutionLevel is "Low", "Moderate", or "High".
4. PreviousStressIncidents is "None" or "Minor".
5. BleachingEventsPerYear is not "Frequent" or "Constant", UNLESS (PollutionLevel is "Low" or "Moderate" AND PreviousStressIncidents is "None" or "Minor" AND BiodiversityIndex is "High"/"Very High" AND ReefIntegrityScore is at least "Good").
6. AlgalCoverage not "Heavy". "Extensive" only if all above are strictly met, PredatorActivityLevel not "High" or worse, and DistantStressIndicators not "Confirmed" or worse—except if all other major indices are best or next-best.
7. DistantStressIndicators is not "Confirmed" or worse IF BleachingEventsPerYear above "Occasional", UNLESS all other major signals are best/next-best (see B5 exception).
8. CurrentFlowQuality is not "Poor", unless all other major signals are best/next-best.
9. No A group rules applied.
- Exception: If DistantStressIndicators is "Confirmed" AND BleachingEventsPerYear is "Constant"/"Frequent", but ALL other indices are best/next-best, assign "Healthy".
C. If neither A nor B applies, assign:
- "Stressed" if there are at least THREE negative signals, at least two from: PreviousStressIncidents above "Minor", DistantStressIndicators is "Confirmed" or worse, PredatorActivityLevel is "High" or worse, PollutionLevel is "High" or worse, BiodiversityIndex is "Medium" or lower, AlgalCoverage is "Heavy" or "Extensive", ReefIntegrityScore is "Poor" or lower, CurrentFlowQuality is "Poor".
- "Stressed" if CurrentFlowQuality is "Poor" and at least two additional negatives (from above) are present.
- "Healthy" otherwise.
Notes:
- "Stressed" always overrides "Healthy".
- Never assign "Stressed" based only on DistantStressIndicators "Confirmed", BleachingEventsPerYear high, or AlgalCoverage "Extensive"/"Heavy" unless at least one or two other negatives (per above).
- Apply these rules EXACTLY as written. Do not interpret or use features not listed above.
