Alarm Escalation - Raising and Routing NectarNet Alarms
Every stream on the NectarNet Mesh is scored against a threshold band by MELISSA. When a band is breached, MELISSA raises an alarm, classifies it into one of four severity tiers, deduplicates it against open incidents, and escalates it to the responders that tier demands. This page documents that pipeline: the severity matrix, the detection-triage-response flow, the per-channel thresholds, and the Black-tier auto-page that pulls in the Director and the response drill.
How MELISSA Raises an Alarm
MELISSA watches NectarNet telemetry continuously, comparing each metric to its calibrated band. A breach opens a candidate alarm; MELISSA enriches it with neighbouring streams, assigns a severity, and either folds it into an existing incident or escalates it. Lower tiers stay on the analytics queue; higher tiers reach people, and the top tier reaches the response & drill ladder automatically. The matrix below defines what each tier means and who it reaches.
Alarm-Severity Matrix
Four tiers, colour-coded from Green to Black. Severity is set by the worst breach contributing to the alarm; an alarm only escalates downward (toward Black), never silently upward.
| Severity | Example trigger | Notified | Response target | Escalation |
|---|---|---|---|---|
| GREEN | All metrics within band; mesh coverage nominal. | Logged only — visible on the Live Command Wall. | — | None; held as baseline. |
| AMBER | Single relay offline; brief floral-load dip; minor colony-weight drift. | NectarNet engineering queue (MELISSA digest). | Next shift | Auto-promotes to Red if the breach persists past one shift. |
| RED | Brood temp out of band; queen-piping signature; sustained weight loss; coverage gap. | On-call apiary tech + duty analyst at the duty desk. | ≤ 30 min | Opens a response drill if unacknowledged in 30 min. |
| BLACK | HCL-4 containment breach; Cryo Vault power loss; neonic spike; multi-node partition. | Director, duty officer, and the full drill ladder. | Immediate | Auto-pages the Director and triggers the drill — see below. |
Detection · Triage · Response
Every alarm moves through the same three stages before it reaches a human.
MELISSA on NectarNet
MELISSA scores each NectarNet stream against its band in real time. A sustained or sharp breach opens a candidate alarm, stamped with the source channel, node, and the telemetry that tripped it. Raw signal keeps flowing to the Live Command Wall even if scoring is degraded.
Auto-classify & dedupe
MELISSA assigns a severity tier from the matrix, then deduplicates: a new alarm that matches an open incident's channel and signature is folded in rather than re-raised, so a single event never floods the desk. Correlated breaches across nodes are merged into one ranked incident.
Route to duty desk / drill
The classified incident is routed to the responders its tier demands — engineering queue, duty desk, or the drill ladder. Acknowledgements, holds, and clears are tracked back on the status board until resolved.
Example Channels & Alarm Thresholds
A sample of the NectarNet channels MELISSA scores, with the band that raises each tier. Every channel maps to a named figure in the Metrics catalogue; thresholds below are the 2091 baseline calibration.
| Channel | Amber | Red | Black | Linked metric |
|---|---|---|---|---|
| Brood temperature | ±0.5 °C drift from 35 °C | Outside 33–36 °C for > 10 min | Outside 30–38 °C — brood loss imminent | Brood Temperature |
| Neonic residue | 1–4 ppb in entrance air | 4–10 ppb confirmed in nectar/pollen | > 10 ppb — acute exposure event | Pesticide Telemetry |
| Mesh coverage | Corridor coverage 95–98% | Coverage 85–95% or cell gap | < 85% or multi-node fabric partition | Corridor Coverage |
| Swarm readiness | Pre-swarm hum + weight plateau | Queen piping + capped swarm cells | Active swarm departure detected | Acoustic Signature |
| Containment integrity | HCL seal pressure drift | HCL-3 seal degraded; airlock fault | HCL-4 breach or Cryo Vault power loss | Containment Integrity |
