Prompt:
You are given ONE reef‑survey record. Decide whether the reef is "Healthy" or "Stressed" by following the steps below EXACTLY and DETERMINISTICALLY. Output ONLY the single word Healthy or Stressed.
STEP 0 – HEALTH OVERRIDE (apply first)
If ALL of the following are true, immediately output Healthy:
• ReefIntegrityScore = Excellent
• PredatorActivityLevel is "None" or "Very Low"
• AcousticIntensity < 300
• BiodiversityIndex = High
STEP 1 – STRESS OVERRIDES (apply next; if any match, output Stressed)
A) PollutionLevel is High or Critical AND InvasiveSpeciesDetected = Yes AND ReefIntegrityScore is Moderate, Poor or Very Poor
B) BleachingEventsPerYear = Constant AND AcousticIntensity < 500
If neither override fired, continue to Step 2.
STEP 2 – ASSIGN RISK POINTS
(a) BleachingEventsPerYear
Rare = 0 Occasional = 1 Frequent = 2 Constant = 2
(b) PollutionLevel
Low = 0 Moderate = 1 High = 3 Critical = 4
(c) ReefIntegrityScore
Excellent = 0 Good = 1 Moderate = 2 Poor = 3 Very Poor = 4
(d) PredatorActivityLevel (treat "Moderate Low" as Moderate; treat "High", "Severe" or "Extreme" the same)
None / Very Low = 0 Moderate / Moderate Low = 1 High / Severe / Extreme = 1
(e) InvasiveSpeciesDetected Yes = 1 No = 0
(f) AcousticIntensity (numeric)
> 900 = 2 500–900 = 1 < 500 = 0
(g) DistantStressIndicators
Confirmed = 1 Possible or Absent = 0
(h) PreviousStressIncidents
None / Minor = 0 Moderate = 1 Severe or worse = 2
STEP 3 – CALCULATE TOTAL RISK
Add all points from Step 2.
STEP 4 – FINAL DECISION
If TOTAL RISK ≥ 9 → Stressed
Otherwise → Healthy
