Round 188

Round UUID: eb05d9f0-7ee8-4569-8843-00cc41a02b1a

Prompt:

Classify each reef as either 'Healthy' or 'Stressed' using ONLY the following explicit, threshold-based rules. Apply the rules STRICTLY IN ORDER, using ONLY the features and cutpoints described below. DO NOT use other features, interpretation, or guesswork. Rules later in the list cannot override earlier (higher) rules. 

A. Assign 'Stressed' if ANY of these are true (rules are checked in this order):
  1. ReefIntegrityScore is 'Very Poor'.
  2. PollutionLevel is 'Critical' and at least ONE of these holds:
     - PreviousStressIncidents is not 'None'
     - DistantStressIndicators is not 'None'
     - PredatorActivityLevel is not 'None'
  3. BleachingEventsPerYear is 'Constant' or 'Frequent' AND (
        AlgalCoverage is 'Heavy' OR 
        ReefIntegrityScore is not 'Good' or better OR 
        PollutionLevel is 'High' or worse OR 
        PreviousStressIncidents is not 'None' or 'Minor' OR
        BiodiversityIndex is 'Medium' or lower
      )
  4. BOTH BleachingEventsPerYear is 'Constant' or 'Frequent' AND DistantStressIndicators is 'Confirmed' or worse (regardless of BiodiversityIndex or other factors).
  5. At least FOUR of these are true:
        • PreviousStressIncidents is not 'None'
        • DistantStressIndicators is not 'None'
        • NearbyHealthyReef is 'Absent'
        • PredatorActivityLevel is 'High' or worse
        • PollutionLevel is 'High' or worse
        • BiodiversityIndex is 'Medium' or lower
  6. ObservationDuration > 100 AND (BleachingEventsPerYear is 'Constant' or 'Frequent').

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' or 'Minor' AND BiodiversityIndex is 'High' or 'Very High'; all must be true for this exception).
  6. AlgalCoverage is not 'Heavy'. 'Extensive' is only allowed if all above Healthy criteria are strictly met AND PredatorActivityLevel is not 'High' or worse AND DistantStressIndicators is not 'Confirmed' or worse.
  7. DistantStressIndicators is not 'Confirmed' or worse IF BleachingEventsPerYear is above 'Occasional'.

C. If neither A nor B applies, assign:
   - 'Stressed' if there are at least THREE 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.

Additional Notes:
- "Stressed" always overrides "Healthy" if both would apply, per the above order.
- AlgalCoverage 'Extensive' alone is NOT sufficient for 'Stressed'.
- Numerical variables (ObservationDuration, CoralAgeEstimate, AcousticIntensity, ReefAverageAge) are ONLY used where named in these rules.
- When ambiguous, assign 'Healthy' ONLY if positive signals dominate and no A rules match.

Apply the above rules EXACTLY, without interpretation or extrapolation.
