-# NeuroScale — Demo Cheat Sheet
-
-> Deterministic demo sequence. Under 3 minutes. Cannot fail.
-
----
-
-## Pre-Demo Setup (run once)
-
-```bash
-# 1. Bootstrap the cluster (5 min first time)
-bash scripts/bootstrap.sh
-
-# 2. Wait for convergence (2-5 min)
-watch kubectl -n argocd get applications
-
-# 3. Open all UIs
-bash scripts/port-forward-all.sh
-
-# 4. Verify everything works
-bash scripts/smoke-test.sh
-```

-## Demo Sequence
-
-### Scene 1: The Broken State (0:00–0:20)
-
-**Show what used to happen.**
-
-```bash
-# Show a non-compliant manifest that would have deployed before
-cat <<'EOF'
-apiVersion: serving.kserve.io/v1beta1
-kind: InferenceService
-metadata:
-  name: bad-model
-  namespace: default
-  # NO owner label
-  # NO cost-center label
-spec:
-  predictor:
-    model:
-      modelFormat:
-        name: sklearn
-      storageUri: "gs://kfserving-examples/models/sklearn/1.0/model"
-      # NO resource limits
-EOF
-echo ""
-echo "Before NeuroScale: this would deploy. No warning. No block."
-```
-
-### Scene 2: Self-Service Golden Path (0:20–0:50)
-
-**Show the Backstage form creating a change.**
-
-```bash
-# Open Backstage
-# Navigate: http://localhost:7010/create
-# Select: "KServe model endpoint"
-# Fill form:
-#   - Endpoint name: my-new-model
-#   - Model format: sklearn
-#   - Owner: ml-platform
-#   - Cost center: cc-ml
-# Click "Create"
-# Show: PR created automatically on GitHub
-```
-
-### Scene 3: CI Refusing a Bad Change (0:50–1:20)
-
-**Show policy enforcement at PR time.**
-
-```bash
-# Try to apply a non-compliant InferenceService directly
-kubectl apply -f - <<EOF
-apiVersion: serving.kserve.io/v1beta1
-kind: InferenceService
-metadata:
-  name: bad-model
-  namespace: default
-spec:
-  predictor:
-    model:
-      modelFormat:
-        name: sklearn
-      storageUri: "gs://kfserving-examples/models/sklearn/1.0/model"
-EOF
-# Expected: Kyverno denies it
-# "admission webhook denied the request: must set metadata.labels.owner and metadata.labels.cost-center"
-```
-
-### Scene 4: GitOps Sync (1:20–1:50)
-
-**Show ArgoCD managing everything.**
-
-```bash
-# Show ArgoCD dashboard - all apps healthy
-# https://localhost:8081
-# Username: admin
-# Password: (from bootstrap output)
-
-# Show the ApplicationSet auto-discovery
-kubectl -n argocd get applications | grep -E "NAME|neuroscale"
-
-# Show self-healing
-kubectl delete deploy nginx-test -n default
-echo "Waiting for ArgoCD to self-heal..."
-sleep 20
-kubectl get deploy nginx-test -n default
-# Result: recreated automatically
-```
-
-### Scene 5: Working Prediction (1:50–2:10)
-
-**Show the endpoint works.**
-
-```bash
-# Get predictor pod
-POD=$(kubectl -n default get pods -l serving.kserve.io/inferenceservice=demo-iris-2 \
-  -o jsonpath='{.items[0].metadata.name}' 2>/dev/null)
-
-# Port-forward to predictor
-kubectl -n default port-forward pod/$POD 18080:8080 &
-sleep 2
-
-# Send prediction
-curl -sS -H "Content-Type: application/json" \
-  -d '{"instances":[[6.8,2.8,4.8,1.4],[6.0,3.4,4.5,1.6]]}' \
-  http://127.0.0.1:18080/v1/models/demo-iris-2:predict
-
-# Expected: {"predictions":[1,1]}
-
-# Kill port-forward
-kill %1 2>/dev/null
-```
-
-### Scene 6: Failure Recovery (2:10–2:40)
-
-**Show operational maturity.**
-
-```bash
-# Simulate ArgoCD repo-server failure
-kubectl -n argocd delete pod -l app.kubernetes.io/name=argocd-repo-server
-
-# Show recovery
-echo "ArgoCD repo-server deleted. Watching recovery..."
-kubectl -n argocd rollout status deploy/argocd-repo-server --timeout=120s
-
-# Verify all apps recovered
-kubectl -n argocd get applications
-# All should show Synced/Healthy
-```
-
-### Scene 7: Final Architecture Shot (2:40–3:00)
-
-```bash
-# Run the full smoke test as the finale
-bash scripts/smoke-test.sh --skip-drift
-# Shows: PASS 21 / FAIL 0
-```

-## If Something Goes Wrong
-
-| Symptom | Fix |
-|---------|-----|
-| ArgoCD shows Unknown | `kubectl -n argocd rollout restart deploy/argocd-repo-server` |
-| InferenceService not Ready | Check KServe controller: `kubectl -n kserve logs deploy/kserve-controller-manager --tail=20` |
-| Backstage CrashLoopBackOff | Check probe values: `kubectl -n backstage describe deploy neuroscale-backstage` |
-| Kyverno not blocking | Check policies: `kubectl get clusterpolicies` |
