Simple drip campaign. User signs up, waits specified delay, sends personalized email, tracks engagement.
```mermaid theme={"theme":"css-variables"}
graph TB
A[userCreateAccount] --> B[sendWelcomeEmail]
B --> C[wait.for 24h]
C --> D[sendProductTipsEmail]
D --> E[wait.for 7d]
E --> F[sendFeedbackEmail]
```
**Router pattern with delay orchestration**. User action triggers campaign, router selects channel based on preferences (email/SMS/push), coordinates multi-day sequence with delays between messages, tracks engagement across channels.
```mermaid theme={"theme":"css-variables"}
graph TB
A[startCampaign] --> B[fetchUserProfile]
B --> C[selectChannel]
C --> D{Preferred
Channel?}
D -->|Email| E[sendEmail1]
D -->|SMS| F[sendSMS1]
D -->|Push| G[sendPush1]
E --> H[wait.for 2d]
F --> H
G --> H
H --> I[sendFollowUp]
I --> J[trackConversion]
```
**Supervisor pattern with approval gate**. Generates AI marketing content (images, copy, assets), pauses with wait.forToken for human review, applies revisions if needed, publishes to channels after approval.
```mermaid theme={"theme":"css-variables"}
graph TB
A[createCampaignAssets] --> B[generateAIContent]
B --> C[wait.forToken approval]
C --> D{Approved?}
D -->|Yes| E[publishToChannels]
D -->|Needs revision| F[applyFeedback]
F --> B
```
**Coordinator pattern with enrichment**. User completes survey, batch triggers parallel enrichment from CRM/analytics, analyzes and scores responses, updates customer profiles, triggers personalized follow-up campaigns.
```mermaid theme={"theme":"css-variables"}
graph TB
A[processSurveyResponse] --> B[coordinateEnrichment]
B --> C[batchTriggerAndWait]
C --> D[fetchCRMData]
C --> E[fetchAnalytics]
C --> F[fetchBehaviorData]
D --> G[analyzeAndScore]
E --> G
F --> G
G --> H[updateCRMProfile]
H --> I[triggerFollowUp]
```
