Round 203

Round UUID: 4daf6e90-1d1b-4abf-90e5-a9cf66a7ca0b

Prompt:

Task: Decide whether the reef described in the incoming JSON‑like record is "Healthy" or "Stressed".

Apply the following deterministic rule set IN THE EXACT ORDER GIVEN (stop at the first rule whose criteria are met).

IMMEDIATE STRESS RULES
1. Hydrodynamic‑Bleach overload (refined)
   If CurrentFlowQuality = Poor AND BleachingEventsPerYear ∈ {Constant, Frequent} AND ReefIntegrityScore ≠ Excellent → Stressed

2. Critical pollution (needs corroboration)
   If PollutionLevel = Critical AND  
      (BleachingEventsPerYear ∈ {Constant, Frequent} OR
       DistantStressIndicators = Confirmed OR
       ReefIntegrityScore ∈ {Poor, Very Poor} OR
       PredatorActivityLevel ∈ {Moderate High, High, Severe, Catastrophic})
   → Stressed

3. Predator surge
   If PredatorActivityLevel = Severe OR Catastrophic AND  
      (BleachingEventsPerYear ∈ {Constant, Frequent} OR
       PollutionLevel ∈ {High, Critical} OR
       DistantStressIndicators = Confirmed)
   → Stressed

4. Bleaching‑plus combo  (unchanged)
   If BleachingEventsPerYear ∈ {Constant, Frequent} AND 
        (PollutionLevel ∈ {High, Critical} OR
         DistantStressIndicators = Confirmed OR
         PredatorActivityLevel ∈ {Moderate High, High, Severe, Catastrophic})
      → Stressed

STRUCTURAL INTEGRITY RULES (new)
5. Structural collapse
   If ReefIntegrityScore = Very Poor → Stressed

6. Compromised integrity combo
   If ReefIntegrityScore = Poor AND at least TWO of the following conditions are present  →  Stressed
      • PollutionLevel ∈ {Moderate, High, Critical}
      • DistantStressIndicators ∈ {Possible, Confirmed}
      • CurrentFlowQuality ∈ {Fair, Poor}
      • BleachingEventsPerYear ∈ {Frequent, Constant}
      • PredatorActivityLevel ∈ {Moderate High, High, Severe, Catastrophic}

TARGETED COMBINATION RULE
7. If PollutionLevel = High AND DistantStressIndicators = Confirmed AND ReefIntegrityScore ∈ {Poor, Very Poor} → Stressed

MULTI‑RISK ACCUMULATION RULE
8. Count how many of the following MODERATE risk signals are present (each counts 1 point):
   a) PollutionLevel = High
   b) BleachingEventsPerYear = Constant OR Frequent
   c) DistantStressIndicators = Confirmed
   d) PredatorActivityLevel = Moderate High OR High OR Catastrophic
   e) ReefIntegrityScore = Poor OR Very Poor
   f) CurrentFlowQuality = Poor
   g) PreviousStressIncidents = Moderate

   • If CurrentFlowQuality = Poor AND count ≥ 3  →  Stressed
   • Otherwise, if count ≥ 4  →  Stressed

DEFAULT RULE
9. If none of the above rules fired → Healthy

Notes & definitions (follow strictly):
• Treat "Very Low" and "Moderate Low" predator levels as LOW (they do NOT count for rules 3, 4, 6 or 8).
• Treat "Moderate High" predator level the same as "High"; treat "Catastrophic" the same as "Severe".
• "Occasional" or "Rare" bleaching do NOT by themselves create risk points.
• Do NOT use AlgalCoverage, NearbyHealthyReef, RemoteSensorPresent, SurveyorExperience or InvasiveSpeciesDetected in your decision; they are considered unreliable indicators.
• Output exactly one of the two labels:  Healthy   or   Stressed  (case sensitive, nothing else).

Once you have applied the rules, output the chosen label on its own line.
