Prompt:
Classify each reef as "Healthy" or "Stressed" according to ONLY the explicit, threshold-based rules described below. Apply the rules STRICTLY IN ORDER as written; do not interpret, interpolate, or use features not explicitly listed in the rules. Once a rule matches, assign immediately and do not check lower rules in the list.
A. Assign "Stressed" if ANY of these are true (check in this order):
1. ReefIntegrityScore is "Very Poor".
2. PollutionLevel is "Critical" AND at least ONE of the following:
- 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 the following: AlgalCoverage is "Heavy" or "Extensive"; ReefIntegrityScore is "Poor" or "Very Poor"; PollutionLevel is "High" or worse; PreviousStressIncidents above "Minor"; BiodiversityIndex is "Medium" or lower)
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)
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. (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. This rule only applies if not already Stressed above, and overrides "Healthy".
SPECIAL PROTECTION: If ALL of these are true — ReefIntegrityScore is "Good" or "Excellent", PollutionLevel is "Low" or "Moderate", PreviousStressIncidents is "None", BiodiversityIndex is "High" or "Very High", PredatorActivityLevel is "Moderate" or lower — then do NOT assign "Stressed" solely for DistantStressIndicators "Confirmed" (or worse), PollutionLevel "Critical" alone, or for BleachingEventsPerYear with one or zero other moderate negative signals.
NOTE: Never assign "Stressed" based ONLY on DistantStressIndicators (of 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 these are true (and NONE of the above A rules match):
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" AND BiodiversityIndex is "High" or "Very High" AND ReefIntegrityScore is at least "Good"; ALL must be true for this exception; DistantStressIndicators "Confirmed" does NOT override in this case if all other signal criteria are at their best or next-best).
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.
7. DistantStressIndicators is NOT "Confirmed" or worse IF BleachingEventsPerYear is above "Occasional", UNLESS all other major signals are best (see B5 exception).
8. CurrentFlowQuality is not "Poor", except if all other major signals are at their best (as for the B5 exception).
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" if both would apply.
- AlgalCoverage "Extensive" or DistantStressIndicators "Confirmed" are NOT sufficient for "Stressed"; only consider with other explicit negatives as above.
- ObservationDuration and other numerical fields are used ONLY as allowed above.
- When ambiguous, assign "Healthy" ONLY if positive signals dominate and no A rules match.
Apply these rules EXACTLY as written. Do not infer, interpolate, or use features not named above.
