+## Pilot Structure
+
+**Four phases — product research, not marketing:**
+
+| Phase | What You Do | What You Learn |
+|-------|-------------|----------------|
+| **1. Collection** | Film, photograph, create observations | What can actually be detected? |
+| **2. Analysis** | Let pipeline create Findings and Decisions | Are decisions understandable and relevant? |
+| **3. Verification** | Compare with reality on site | Was the recommendation correct? |
+| **4. Reflection** | Document what worked and what didn't | What needs to change in the model? |
+
+**Full chain captured:**
+```
+Reality → Observation → Evidence → Finding → Decision → Action → Outcome → Learning
+```
+
+## What to Measure
+
+**Not:** Did AI find a crack?
+**But:** Did this become a decision a real person could act on?
+
+**Example:**
+- AI finds 23 cracks
+- LandveX says: "Inspect Road A12 within 30 days"
+- **The second is the product.**
+
+## Document "Non-Decisions"
+
+Also valuable:
+- "No action needed"
+- "More data required"
+- "Cannot recommend anything yet"
+
+If the system always tries to give advice even when evidence is weak, you risk building a system that feels confident when it shouldn't.
+
+## Film the Workflow
+
+Since you are conducting the pilots, film more than just infrastructure. Also film:
+- How you find an area
+- Why you choose a mission
+- How you document
+- How long it takes
+- What feels unclear
+- When you become uncertain
+- When the system saves time
+
+This material becomes invaluable for product development, onboarding, training, and sales.
+
+## Observer Mindset
+
+**Principle:** If data contradicts the model, the model should change.
+
+Use the same approach during pilots. If you notice:
+- A step feels unnecessary
+- A decision becomes unclear
+- A recommendation cannot be acted on
+
+**Document first, change model later.** Build the model from real workflows instead of assumptions.
+
+**The first 20–50 real missions will give you more valuable product knowledge than months of additional modeling.**
