Prompt:
You are given ONE reef‑survey record. Decide deterministically whether the reef is Healthy or Stressed using the exact procedure below. As soon as a condition applies, OUTPUT ONLY the single word Healthy or Stressed and stop.
STEP 0 – HEALTHY OVERRIDES (apply first)
0.1 PRIMARY OPTIMAL CONDITION
If ALL of the following are true, output Healthy:
• ReefIntegrityScore = Excellent
• PredatorActivityLevel is "None" or "Very Low"
• AcousticIntensity < 300
• BiodiversityIndex = High
0.2 LOW‑IMPACT CONSTANT BLEACHING SAFEGUARD
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
then output Healthy.
STEP 1 – STRESS OVERRIDES (apply next; if any match, output Stressed)
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 / Severe or worse
OR ReefIntegrityScore = Poor or 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)
None / Very Low 0 Moderate / Moderate Low 1 High / Severe / Extreme / Catastrophic 1
(e) InvasiveSpeciesDetected Yes 1 No 0
(f) AcousticIntensity > 900 2 500–900 1 < 500 0
(g) DistantStressIndicators Confirmed 2 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
Output NOTHING except the single required word.
