Round 307

Round UUID: d53b5770-6626-441d-9b51-705a4ec23950

Prompt:

You are given ONE reef‑survey record.  Decide deterministically whether the reef is Healthy or Stressed.  Output ONLY the single word Healthy or Stressed.

STEP 0 – PRIMARY HEALTH OVERRIDES  (apply first)
0.1  If ALL of the following are true, immediately output Healthy
     • ReefIntegrityScore = Excellent
     • PredatorActivityLevel is "None" or "Very Low"
     • AcousticIntensity < 300
     • BiodiversityIndex = High

0.2  LOW‑IMPACT CONSTANT BLEACHING – additional Healthy safeguard
     If BleachingEventsPerYear = Constant
        AND AcousticIntensity < 200
        AND PollutionLevel = Low
        AND DistantStressIndicators = None
     then output Healthy.

STEP 1 – STRESS OVERRIDES  (apply next; if any match, output Stressed)
1.A  PollutionLevel is High OR Critical  AND  InvasiveSpeciesDetected = Yes  AND  ReefIntegrityScore is Moderate, Poor or Very Poor

1.B  INTENSIFIED CONSTANT BLEACHING
     BleachingEventsPerYear = Constant  AND  AcousticIntensity < 500
     AND ( ReefIntegrityScore is Moderate, Poor or Very Poor
            OR PollutionLevel is Moderate / High / Critical
            OR DistantStressIndicators = Confirmed )
     → 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 "High", "Severe", "Extreme" the same)
      None / Very Low = 0   Moderate / Moderate Low = 1   High / Severe / Extreme = 2
(e) InvasiveSpeciesDetected   Yes = 1   No = 0
(f) AcousticIntensity (numeric)
      > 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.

STEP 4 – FINAL DECISION
If TOTAL RISK ≥ 9  →  Stressed
Otherwise            →  Healthy

Do NOT output anything except the single word result.
