+# Prod Event Example (prod_event_example)
+
+Demonstrates branch-scoped event triggering where only the production
+(main branch) deployment reacts to external signals. Shows the difference
+between `@project_trigger`, `@trigger_on_finish`, `@schedule`, and `@trigger`.
+
+## Platform Features Used
+
+- **Events**: `@project_trigger(event="external_signal")` for branch-scoped external events; `prj.safe_publish_event("ingest_complete")` for internal events
+- **Schedules**: `@schedule(cron="0 8 * * 1-5")` weekday morning ingest
+- **Flow chaining**: `@trigger_on_finish(flow="EventProcessorFlow")` (auto branch-scoped)
+- **Dev-assets**: `[dev-assets] branch = "main"` for cross-branch data reads
+
+## Flows
+
+| Flow | Trigger | Purpose |
+|------|---------|---------|
+| ScheduledIngestFlow | @schedule(cron) | Daily ingest, publishes `ingest_complete` event |
+| EventProcessorFlow | @project_trigger(external_signal) | Processes external events, branch-isolated |
+| ChainedReporterFlow | @trigger_on_finish(EventProcessor) | Reports after event processing |
+
+## Event Scoping
+
+`@project_trigger` creates sensors scoped to `prj.<project>.<branch>.<event>`:
+- Main: `prj.prod_event_example.main.external_signal`
+- Feature branch: `prj.prod_event_example.<branch>.external_signal`
+
+External systems target prod by publishing to the `main` event name explicitly.
+
+## Run Locally
+
+```bash
+cd prod-event-example
+python flows/scheduled_ingest/flow.py run
+python flows/event_processor/flow.py run
+# chained_reporter requires an upstream run in Argo (uses current.trigger.run)
+```
+
+## Common Pitfalls
+
+- `@trigger(event=...)` is NOT branch-scoped -- all branches react to the same event. Use `@project_trigger` instead.
+- ChainedReporterFlow cannot run locally without a trigger context (`current.trigger.run` would be None)
+- External event publishers must specify both project and branch to target the correct deployment
+- See TESTING.md for the full verification plan including branch isolation tests
