4A: The Nested Pyramid
"In a control tower, clear sightlines are everything. If a controller has to look through five different windows just to see the runway, they're going to miss a signal. In code, Nested If-Statements create a "Pyramid" that obscures the main logic path. A skilled Engineer audits for Guard Clauses."
The Concept: Guard Clauses
A Guard Clause is a technique where you check for "Failure Conditions" at the very beginning of a method and exit immediately if they aren't met.
Exit Early: If a ship has no fuel, don't check for engine temperature—just return.
The Two-Tab Rule: If your code is indented more than two "tabs" deep, your logic is likely over-complicated.
Flatten the Pyramid: Move nested checks into their own methods.

The AI Trap: "The Pyramid of Doom"
You ask the AI: "Only fire the thrusters if the key is pressed, we have fuel, and the landing gear is retracted."
// AI-Generated Code: Visual & Logic Fatigue
void Update() {
if (Input.GetKey(KeyCode.Space)) {
if (hasFuel) {
if (isGearRetracted) {
ExecuteThrusters(); // Audit Fail: Too many layers!
}
}
}
}
This is "Cognitive Load." To understand what allows ExecuteThrusters() to run, your brain has to remember three separate "True" conditions at once. If you add a fourth check, the code becomes a maze.
Elite Telemetry
Research shows "Elite" teams achieve 15% faster lead times by keeping AI on a "very tight leash."
- Small Batches Solving one problem at a time prevents logic drift.
- Modular Design Localizing the "blast radius" of AI changes.
- Tight Loops Rapid iteration with constant code review.
The Mechanic's Correction
Corrective Protocol
void Update() {
// Corrected: Clear sightlines.
if (!Input.GetKey(KeyCode.Space)) return;
if (!hasFuel) return;
if (!isGearRetracted) return;
// The Success Path is now clean and top-level.
ExecuteThrusters();
