| NFR‑ID | Description | Target | |--------|-------------|--------| | NFR‑001 | – End‑to‑end detection (sensor → alert) ≤ 250 ms for high‑frequency streams. | 250 ms | | NFR‑002 | Resource Footprint – ≤ 300 MB RAM, ≤ 1 W CPU on MEYD‑675 ARM‑Cortex‑A53. | 300 MB / 1 W | | NFR‑003 | Scalability – One hub can manage up to 200 sensors; horizontally scale to thousands of hubs via Kubernetes at the cloud tier. | 200 sensors/hub | | NFR‑004 | Reliability – 99.9 % uptime for the edge runtime; automated watchdog restart. | 99.9 % | | NFR‑005 | Data Retention – Raw sensor data kept locally for 48 h; aggregated metrics persisted 90 days in cloud. | 48 h / 90 days | | NFR‑006 | Usability – Dashboard onboarding < 15 min; “Explain‑Why” drill‑down ≤ 2 clicks. | 15 min / 2 clicks | | NFR‑007 | Compliance – GDPR‑compatible data handling, optional anonymisation of device IDs. | GDPR‑ready | | NFR‑008 | Maintainability – All edge components containerised; CI/CD pipeline with automated regression testing (≥ 90 % code coverage). | CI/CD ready |

Meyd675 sat at the edge of the old arcade, fingers hovering above a cracked joystick as neon reflections trembled across the glass. Nobody in the neighborhood used that handle name anymore—Meyd675 belonged to a different era, a digital ghost whose high scores still blinked on the leaderboard like tiny beacons. meyd675
