+## Prefect — Orchestration Layer (Jenkins for Claude Code)
+
+[Prefect](https://www.prefect.io/) as the workflow orchestration layer for GHA CI executor:
+
+- Prefect manages flow scheduling, retries, observability, and state persistence
+- Each executor task = a Prefect flow: Analysis Agent → GHA trigger → monitor → result
+- Eagle submits tasks to Prefect; Prefect handles retry logic, parallel runs, timeouts
+- Prefect UI gives visibility into all executor runs (instead of Zulip-only status)
+- Can replace or wrap the current cron-based executor tick
+- Self-hosted Prefect server on Eagle or VPS (or Prefect Cloud free tier)
+
+**How it fits:**
+```
+Eagle / Asana → Prefect flow submitted
+                    ↓
+               Prefect orchestrates:
+                 1. Analysis agent (Claude): read task, generate prompt
+                 2. Trigger GHA workflow via gh CLI
+                 3. Monitor GHA job status (poll or webhook)
+                 4. On complete: post result to Asana, notify Eagle
+                    ↓
+               Retry on failure, log all state
+```

 ## Notes
 
 - GHA macos-15 runners do NOT have Xcode pre-cached — each run installs from scratch
