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):
1. ReefIntegrityScore is "Very Poor".
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"
3. BleachingEventsPerYear is "Constant" or "Frequent" AND (at least TWO of: AlgalCoverage is "Heavy" or "Extensive"; ReefIntegrityScore is "Poor" or "Very Poor"; PollutionLevel is "High" or worse; PreviousStressIncidents above "Minor"; BiodiversityIndex is "Medium" or lower), AND at least one of these two is either PreviousStressIncidents above "Minor", PollutionLevel is "Critical", or BiodiversityIndex is "Medium" or lower—unless two (or more) severe stress signals in A5 occur.
4. BleachingEventsPerYear is "Constant" or "Frequent" AND DistantStressIndicators is "Confirmed" or worse AND (at least TWO of: PollutionLevel is "High" or worse; ReefIntegrityScore is below "Good"; PreviousStressIncidents is not "None"; PredatorActivityLevel is "High" or worse; BiodiversityIndex is "Medium" or lower), AND at least one of these two is either PollutionLevel is "Critical", PreviousStressIncidents is above "Minor", or BiodiversityIndex is "Medium" or lower—unless two (or more) severe stress signals in A5 occur.
5. At least TWO of these SEVERE stress signals:
• PreviousStressIncidents above "Minor"
• DistantStressIndicators is "Confirmed" or worse
• PredatorActivityLevel is "High", "Severe", or "Extreme"
• PollutionLevel is "High" or "Critical"
• BiodiversityIndex is "Medium" or lower
• CurrentFlowQuality is "Poor" AND at least one other item in this list
6. ObservationDuration > 100 AND BleachingEventsPerYear is "Constant" or "Frequent" AND at least one other stress signal from list in A5.
7. NEW: If ObservationDuration > 120 AND at least TWO of the following are present: 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"; AND BleachingEventsPerYear is above "Rare"—assign "Stressed" (chronic stress exception).
8. (Aggregate Moderate Stress Trigger) If at least THREE of these moderate/major negatives are present AND at least ONE is CurrentFlowQuality "Poor": PreviousStressIncidents above "Minor", 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, DistantStressIndicators is "Possible" or worse. Apply only if not already Stressed above; this rule overrides "Healthy".
SPECIAL PROTECTION (REVISED): If ALL are true — ReefIntegrityScore is "Good" or "Excellent", PollutionLevel is "Low" or "Moderate", PreviousStressIncidents is "None" OR "Minor", BiodiversityIndex is "High" or "Very High", PredatorActivityLevel is "Moderate Low", "Moderate" or lower — then do NOT assign "Stressed" solely for DistantStressIndicators "Confirmed" (or worse), PollutionLevel "Critical" alone, or for BleachingEventsPerYear (any frequency) if only a single other moderate/major negative is present. Require at least TWO additional negatives (besides DistantStressIndicators, PollutionLevel, or Bleaching frequency) to assign "Stressed".
REFINED EXCEPTION: Never assign "Stressed" based ONLY on a single negative in the A2–A5 group above when all other major indices (ReefIntegrityScore, PollutionLevel, PreviousStressIncidents, BiodiversityIndex, PredatorActivityLevel) are at their best or next-best (e.g., "Excellent"/"Good", "Low"/"Moderate", "None"/"Minor", "High"/"Very High", "Moderate Low"/"Moderate" or lower).
NOTE: Never assign "Stressed" based ONLY on DistantStressIndicators (any level), CurrentFlowQuality, or AlgalCoverage unless at least TWO other severe indicators from the A5 group are present.
B. Assign "Healthy" IF AND ONLY IF ALL of the following, and NONE of A applies:
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" or "Very High" AND ReefIntegrityScore is at least "Good").
6. AlgalCoverage is NOT "Heavy". "Extensive" is ONLY allowed if all above criteria are strictly met, PredatorActivityLevel is not "High" or worse, and DistantStressIndicators not "Confirmed" or worse — except if all other major indices are at their best or next-best value.
7. DistantStressIndicators is NOT "Confirmed" or worse IF BleachingEventsPerYear is above "Occasional", UNLESS all other major signals are best or next-best (see B5 exception).
8. CurrentFlowQuality is not "Poor", except if all other major signals are at their best or next-best ("Excellent"/"Good" ReefIntegrityScore, "Low"/"Moderate" PollutionLevel, "High"/"Very High" BiodiversityIndex, "None"/"Minor" PreviousStressIncidents, "Moderate Low"/"Moderate" or lower PredatorActivityLevel).
B-EXCEPTION: If both DistantStressIndicators is "Confirmed" AND BleachingEventsPerYear is "Constant" or "Frequent", but all other major indices (as above) are at their best or next-best, assign "Healthy".
C. If neither A nor B applies, assign:
- "Stressed" if there are at least THREE negative signals, of which at least TWO must be 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".
- "Healthy" otherwise.
Notes:
- "Stressed" always overrides "Healthy".
- Neither AlgalCoverage "Extensive" nor DistantStressIndicators "Confirmed" alone or with one moderate/major negative suffice for "Stressed"; require (a) additional major negatives or (b) all best/protected indices for a "Healthy" assignment as above.
- ObservationDuration and other numerical fields are used ONLY as specified above.
- When ambiguous, assign "Healthy" ONLY if positive signals dominate and no A rules match.
Apply these rules EXACTLY as written. Do not interpret or use features not listed above.
