Healthy-Surface Index (HSI)
How much honest ground a population can reach. Where healthy surfaces vanish, users are left scavenging in an attention desert.
Interpretation
This metric provides operational visibility into reach & coverage performance. Changes in value should be interpreted in the context of current threat levels and recent counter-operations. GOVERNOR uses this reading alongside related metrics to maintain a composite picture of directorate readiness.
Formula
Thresholds & Bands
| Band | Range | State |
|---|---|---|
| Abundant | ≥ 70 | ok |
| Sparse | 40-70 | warn |
| Desert | < 40 | crit |
Data Collection
Collected by the Instrumentation Mesh probe network. Each mesh node reports raw readings at its configured interval; the relay layer deduplicates and forwards to GOVERNOR for smoothing and threshold evaluation.
GOVERNOR Behavior
Abundant (≥ 70): GOVERNOR logs the reading, updates the standing dashboard, and takes no further action. Sparse (40-70): GOVERNOR escalates to an advisory notification. The on-duty watch officer receives an alert, and the metric is flagged in the next Steward briefing if the condition persists for two consecutive reporting periods. Desert (< 40): GOVERNOR triggers an immediate escalation. The Steward is notified directly, the relevant department head is paged, and all related dashboards enter amber-alert mode until the reading recovers above the warning threshold.
