# Sentinel V5.7 architecture

V5.7 deliberately avoids decorative controls.

Visible administration controls call real FastAPI JSON endpoints and
write to `data/sentinel_monitoring.db`.

The rule engine currently executes simple threshold comparisons against
real latest measurement fields. It supports Site, Group and Equipment
scope.

Suppression windows do not erase alarms. They mark matching alarms as
suppressed while retaining the alarm and audit event.

Group permission records are persisted but cannot yet be enforced
per-user because login/authentication is not part of V5.7.
