+
+## ✅ What Was Completed in Day 3
+
+### 1. **Task 2: Cascading Failure (Medium Difficulty)**
+**File:** `server/scenarios/cascading.py` (171 lines)
+
+✅ **Scenario Definition:**
+- Database slowdown in user-db → exhausts auth-service connection pool → cascade to api-gateway
+- Surface logs show gateway errors loudly (symptom), but root cause is hidden (user-db)
+- Agent must trace backward through the cascade chain, not treat symptoms
+
+✅ **Ground Truth:**
+```
+Severity:    P1
+Root Cause:  user-db (NOT auth-service, NOT api-gateway)
+Remediation: kill-query:user-db OR restart:user-db
+Teams:       dba-team, sre-team
+Max Steps:   12
+Noise:       30%
+```
+
+✅ **Step-by-Step Signal Plan (12 stages):**
+- Step 0-1: Gateway errors appear (symptoms only)
+- Step 2-3: Auth-service DB pressure becomes visible
+- Step 4-5: user-db slow queries exposed; circuit breaker opens
+- Step 6-7: Full cascade; all 3 services degraded/down
+- Step 8-11: Escalating alerts; root cause becomes unmistakable
+
+✅ **System State Modeling:**
+- api-gateway: degrades from 8% error → 99% error
+- auth-service: degrades from healthy → down by step 6
+- user-db: shows latency increase from 2847ms → 10000ms
+
+✅ **Integration:**
+- Wired to environment.py as `cascading_failure` task
+- Accessible via `/reset?task=cascading_failure`
+- Returns realistic logs with 30% noise injected
+
+---
+
+### 2. **Task 3: Silent Degradation (Hard Difficulty)**
+**File:** `server/scenarios/silent_degrade.py` (185 lines)
+
+✅ **Scenario Definition:**
+- payment-db query latency slowly increases over time
+- No service crashes; error rate stays below P1 threshold (5%)
+- 60% of logs are irrelevant noise from other services
+- Agent must filter noise, identify subtle signal, and classify as P2 (not P1, not P3)
+
+✅ **Ground Truth:**
+```
+Severity:    P2 (NOT P1, NOT P3 — nuanced judgment required)
+Root Cause:  payment-db
+Remediation: flush-cache:payment-db OR kill-query:payment-db
+Teams:       dba-team
+Max Steps:   15
+Noise:       60% (hardest noise ratio of all tasks)
+```
+
+✅ **Step-by-Step Signal Plan (15 stages):**
+- Step 0-2: Very subtle signals (payment-db latency 450ms → 890ms)
+- Step 3-5: Buffer cache degradation visible; error rate at 2.1%
+- Step 6-8: Latency 2200ms → 3100ms; still well below P1 threshold
+- Step 9-12: Approaching but not breaching timeout (4200ms → 4600ms)
+- Step 13-14: P1 breach imminent/breached (4950ms → payment error 5.1%)
+
+✅ **Noise Characteristics:**
+- Most logs are from unrelated services (api-gateway, auth-service, etc.)
+- Signal is sparse — only 1-2 relevant logs per step
+- Requires agent to carefully read logs and filter signal from noise
+
+✅ **System State Modeling:**
+- payment-db: latency increases 450ms → 4950ms, status stays "up" until step 3
+- payment-service: becomes slightly degraded from step 4 onward
+- All other services: remain in healthy state
+
+✅ **Integration:**
+- Wired to environment.py as `silent_degradation` task
+- Accessible via `/reset?task=silent_degradation`
+- Returns realistic logs with 60% noise injected
+
+---
+
+### 3. **Environment Wiring (Updated)**
+**File:** `server/environment.py` (updated)
+
+✅ **Imports Added:**
+```python
+from server.scenarios import cascading
+from server.scenarios import silent_degrade
+```
+
+✅ **Task Registry Updated:**
+```python
+TASK_MAX_STEPS = {
+    "single_crash":      8,
+    "cascading_failure": 12,
+    "silent_degradation": 15,
+}
+```
+
+✅ **reset() Method Wired All 3 Tasks:**
+```python
+if task_id == "single_crash":
+    self._ground_truth = single_crash.GROUND_TRUTH
+elif task_id == "cascading_failure":
+    self._ground_truth = cascading.GROUND_TRUTH
+elif task_id == "silent_degradation":
+    self._ground_truth = silent_degrade.GROUND_TRUTH
+```
+
+✅ **_get_step_data() Extracts Scenario Data:**
+- Calls `scenario.get_step_data(step, base_time, rng)` for real logs
+- Calls `scenario.get_system_state(step, base_time)` for service status
+- All 3 tasks return deterministic logs based on ground truth
+
+✅ **_get_alerts() Returns Scenario-Specific Alerts:**
+- Each scenario defines its own alert progression
+- Alerts evolve as cascade/degradation unfolds
+

+
+## 🎮 All 3 Tasks Now Playable End-to-End
+
+### **Task 1: Single Service Crash (Easy)**
+```bash
+curl -X POST "http://localhost:7860/reset?task=single_crash&seed=42"
+curl -X POST "http://localhost:7860/step" \
+  -H "Content-Type: application/json" \
+  -d '{"action_type":"classify_severity","value":"P1","confidence":0.95}'
+# Expected: +0.30 reward for correct severity
+```
+
+### **Task 2: Cascading Failure (Medium)**
+```bash
+curl -X POST "http://localhost:7860/reset?task=cascading_failure&seed=42"
+curl -X POST "http://localhost:7860/step" \
+  -H "Content-Type: application/json" \
+  -d '{"action_type":"request_more_logs","value":"system_state","confidence":0.9}'
+# Agent must trace: gateway errors → auth-service → user-db (root cause)
+# Expected: +0.35 reward for identifying user-db (not gateway/auth-service)
+```
+
+### **Task 3: Silent Degradation (Hard)**
+```bash
+curl -X POST "http://localhost:7860/reset?task=silent_degradation&seed=42"
+curl -X POST "http://localhost:7860/step" \
+  -H "Content-Type: application/json" \
+  -d '{"action_type":"classify_severity","value":"P2","confidence":0.85}'
+# Nuanced judgment: error rate is 2.1% (below P1 @ 5%) but trending toward breach
+# Expected: +0.30 reward for correct P2 (not P1, not P3)
+```
+
+---
+
+## 📈 Scoring Distribution
+
+Each task has different difficulty → different expected agent score ranges:
+
+| Task | Difficulty | Max Score | Expected Range | Key Challenge |
+|------|-----------|-----------|-----------------|---------------|
+| **Single Crash** | Easy | 1.00 | 0.75–0.85 | Simple identification |
+| **Cascading** | Medium | 1.00 | 0.45–0.60 | Trace root cause, not symptoms |
+| **Silent Degrade** | Hard | 1.00 | 0.20–0.40 | Filter 60% noise, nuanced P2 judgment |
+
+---
