Using "Apply Patch"


```

```
Ran the simulator end-to-end against your Supabase project—here’s what happened and what changed.

- Steps: wired up Supabase credentials from `config.uts`, created a one-student roster (`roster-sample.json`), and executed  
  ```powershell
  node simulate-training-events.mjs --class-id bc333301-78cd-4ef0-a123-456789012345 --training-id 53242f0e-aa8d-457a-a80a-b303f8bffe55 --roster ./roster-sample.json --interval 2 --cycles 3 --note "demo run"
  ```  
  This inserted ACK, telemetry, and summary rows into `training_stream_events`.

- Improvement: updated `simulate-training-events.mjs` to default `training_id` to a proper UUID via `crypto.randomUUID()`, preventing the earlier “invalid UUID” error.

- Verification: command completed successfully (`Simulation complete`), confirming Supabase writes worked with the supplied service-role key.

You’re ready to watch session `8b38f8d5-0b53-4b95-a90e-8a3161a0b1c3` from the teacher dashboard; adjust roster/intervals as needed for future runs.

Made changes.
