Prompt:
You are given ONE reef‑survey record. Decide deterministically whether the reef is Healthy or Stressed by following the steps below EXACTLY. As soon as ANY condition is satisfied, OUTPUT only the single word Healthy or Stressed and stop. Do NOT output anything else.
STEP 0 – IMMEDIATE HEALTHY OVERRIDES
0.1 PRIMARY OPTIMAL CONDITION
Healthy if ALL are true:
• ReefIntegrityScore = Excellent
• PredatorActivityLevel is None or Very Low
• AcousticIntensity < 300
• BiodiversityIndex = High
0.2 LOW‑IMPACT CONSTANT‑BLEACHING SAFEGUARD
Healthy if BleachingEventsPerYear = Constant
AND AcousticIntensity < 150
AND PollutionLevel = Low
AND PredatorActivityLevel is None / Very Low / Moderate Low
AND PreviousStressIncidents = None / Minor
AND ReefIntegrityScore is Moderate, Good or Excellent
AND AlgalCoverage is Minimal or Moderate
0.3 RESILIENT EXCELLENT REEF (new)
Healthy if ALL are true:
• ReefIntegrityScore = Excellent
• BiodiversityIndex = High
• PredatorActivityLevel is None / Very Low / Low / Moderate Low
• BleachingEventsPerYear ≠ Constant (i.e. Rare / Occasional / Frequent)
• AcousticIntensity < 700
• CurrentFlowQuality = Good or Excellent
STEP 1 – IMMEDIATE STRESS OVERRIDES
1.A POLLUTION + INVASIVES + WEAK INTEGRITY
PollutionLevel is High OR Critical
AND InvasiveSpeciesDetected = Yes
AND ReefIntegrityScore is Moderate, Poor or Very Poor
→ Stressed
1.B CONSTANT BLEACHING WITH COMPOUND STRESS
BleachingEventsPerYear = Constant
AND AcousticIntensity ≥ 200
AND ( PredatorActivityLevel is High / Severe / Extreme / Catastrophic
OR PollutionLevel is Moderate / High / Critical
OR DistantStressIndicators = Confirmed
OR PreviousStressIncidents = Moderate or worse
OR ReefIntegrityScore = Poor or Very Poor )
→ Stressed
1.C CONFIRMED LARGE‑SCALE STRESS ON WEAK REEF (new)
DistantStressIndicators = Confirmed
AND InvasiveSpeciesDetected = Yes
AND ReefIntegrityScore is Moderate / Poor / Very Poor
→ Stressed
STEP 2 – ASSIGN RISK POINTS
(a) BleachingEventsPerYear Rare 0 Occasional 1 Frequent 3 Constant 4
(b) PollutionLevel Low 0 Moderate 2 High 4 Critical 5
(c) ReefIntegrityScore Excellent 0 Good 1 Moderate 2 Poor 3 Very Poor 4
(d) PredatorActivityLevel (treat "Moderate Low" as Moderate; treat "Low" same as None/Very Low)
None / Very Low / Low 0 Moderate / Moderate Low 1 High / Severe / Extreme / Catastrophic 2
(e) InvasiveSpeciesDetected Yes 1 No 0
(f) AcousticIntensity > 900 2 500–900 1 < 500 0
(g) DistantStressIndicators Confirmed 3 Possible 1 Absent 0
(h) PreviousStressIncidents None / Minor 0 Moderate 1 Severe or worse 2
STEP 3 – CALCULATE TOTAL RISK
Add all points from Step 2 to obtain TOTAL_RISK.
STEP 4 – FINAL DECISION
If TOTAL_RISK ≥ 9 → Stressed
Else → Healthy
Remember: output ONLY the word Healthy or Stressed and nothing else.
