 The **Afritic Open Farming Standard (AOFS)** is built on a set of guiding principles that ensure **safety, reliability, scalability, and productive use of resources**. These principles form the foundation for all AOFS-compliant systems, controllers, and modules.
-AOFS is **designed not only to be safe and fail-proof, but also to be smart** — capable of learning, predicting, and optimizing operations in environments where infrastructure is intermittent or unreliable. This is especially relevant in regions of Africa, where grid power or water supply may only be available sporadically. AOFS can **observe patterns, estimate probabilities, and make intelligent decisions** while **always respecting local safety thresholds**.
+AOFS is **not only safe and fail-proof, it is smart** — capable of **learning, predicting, and optimizing operations** even under intermittent infrastructure conditions. In many regions of Africa, **grid electricity or water supply may only be available sporadically**. AOFS can **observe patterns, estimate probabilities, and make intelligent operational decisions** while always respecting **local safety thresholds**.
 ===== 1. Local Autonomy =====

+  * AOFS **learns patterns of intermittent grid power and water availability**. When predictive sensors are installed:
-    * The system can anticipate when power or water is likely to be available.
+    * The system can anticipate when electricity or water is likely to be available.

+    * All predictive actions **strictly respect local fail-safe limits**.
 ===== 2. Fail-Safe Operation =====

   * Sensors and actuators enforce local safety decisions independently of higher-level controllers.
   * Redundant or passive protection mechanisms (float switches, overflow pipes, battery cutoffs) **must be included**.
-  * Even when using predictive knowledge of grid availability:
+  * Predictive use of intermittent resources **cannot override safety thresholds**:
-    * AOFS **immediately disconnects power if voltage, current, or frequency are outside safe limits**.
+    * Grid power is immediately disconnected if voltage, current, or frequency are unsafe.
-    * AOFS **never allows predictive logic to override mandatory water levels**, protecting crops and livestock.
+    * Water levels are always maintained above critical minimums.
+    * If grid power is unavailable, **AOFS can automatically activate backup generators or other local energy sources** to meet minimal operational requirements.
 ===== 3. Separation of Control and Supervision =====
   * **Field Controllers** make authoritative operational decisions.
   * **Farm and HQ Controllers** monitor, configure, and analyze — they **cannot override critical safety logic locally**.
-  * Predictive or probabilistic data (grid power or water availability) is **advisory**: the Field Controller decides how and when to act based on safety and operational rules.
+  * Predictive or probabilistic data (grid power or water availability) is **advisory**: the Field Controller determines the actual operational response.
   * Human operators can supervise and adjust parameters, but **local safety constraints always take precedence**.
 ===== 4. Scalability & Replicability =====
   * AOFS supports a wide range of farm sizes, from **smallholder plots to multi-hectare commercial operations**.
-  * Architecture, data models, and interfaces are designed to be **modular, replicable, and extensible** across farm types and geographies.
