## Actual source change

Codex added Comfort margin to the Node-RED flow, API, telemetry schema and dashboard, and aligned the CNC example temperature limit and boundary fixture from 32 °C to 30 °C. Missing temperature returns null and displays as Unavailable.

## Measured application data

- Independent functional checks: 32/32 kontroller — Public feature matrix for Comfort margin, scenario isolation, fault state and recovery. (observed 2026-10-18T13:42:21Z; source: https://teachthecompany.com/node-lab/capture/)
- Validated schema snapshots: 9/9 prøver — Saved telemetry snapshots validated against the schema with Ajv draft 2020-12. (observed 2026-10-18T13:42:21Z; source: https://teachthecompany.com/node-lab/source/telemetry.schema.json)
- Server sequence: 253–294 prøver — New anonymous 61-second observation of the normal scenario; sequence and server time advanced. (observed 2026-10-18T13:49:55Z; source: https://teachthecompany.com/node-lab/api/live?scenario=normal)
- Generator interval: 1.5 sekunder — Configured interval for backend-generated emulated workshop samples. (observed 2026-10-18T13:49:55Z; source: https://teachthecompany.com/node-lab/api/info)
- Source unit tests: 12/12 tester — Bounded unit tests for the published Comfort margin change. (observed 2026-10-18T13:42:21Z; source: https://teachthecompany.com/node-lab/capture/change-validation.json)
