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.
