+# Experiment: Network Partition Mid-Batch
+Date: 2026-06-24
+Phase: 24 — Climate Resilience Verification
+
+## 1. Hypothesis
+If I disconnect the ward gateway from the central Docker network while it accepts
+observations, I expect events to buffer locally and fleet status to show DEGRADED,
+because sync upload cannot reach central until the partition heals.
+
+## 2. Baseline
+- Encounter: `0f81a139-9f33-47ad-9df9-09c7a6c011c8`
+- Gateway status: ONLINE
+- Gateway buffer depth: 0
+- Central observation count: 14
+
+## 3. Break
+```bash
+GATEWAY_CONTAINER=$(docker ps -qf name=ward-gateway-api)
+NETWORK=$(docker network ls --format '{{.Name}}' | grep vigilcare | head -1)
+docker network disconnect "$NETWORK" "$GATEWAY_CONTAINER"
+
+curl -X POST "http://localhost:5081/api/v1/encounters/$ENCOUNTER_ID/observations" \
+  -H "Authorization: Bearer $GATEWAY_JWT" \
+  -H "Content-Type: application/json" \
+  -d '{"observationCode":"HEART_RATE","value":165,"unit":"bpm","source":"DEVICE",
+       "recordedAt":"<UTC-now>","idempotencyKey":"partition-exp2-1782245574"}'
+```
+
+## 4. Observe
+- Gateway accepted observation locally (HTTP 201)
+- Fleet status transitioned to **DEGRADED** (`reportedBufferDepth: 2`)
+- Gateway DB unsynced buffer count: **2**
+- Central could not receive the observation during partition
+- `minutesSinceHeartbeat` remained near zero (gateway process still running)
+
+## 5. Fix / Outcome
+- Bug found? **no**
+- Fix applied: no fix needed — by design
+
+## 6. Verify
+(Post-heal results in `2026-06-24-partition-mid-batch-fixed.json`)
