Constraint Name

[Constraint Name] - CRITICAL REQUIREMENT

[One-line summary of the architectural principle.]

[Brief explanation of what this means and why it matters - 2-3 sentences max.]

What Violates This Constraint

1. [Violation Category 1]

// FORBIDDEN: [Description of what's wrong]
[code example]

Why it's wrong: [Explanation of consequences]

Correct approach:

// CORRECT: [Description of the fix]
[code example]

2. [Violation Category 2]

// FORBIDDEN: [Description]
[code example]

Why it's wrong: [Explanation]

Correct approach:

// CORRECT: [Description]
[code example]

Where [Constrained Code] IS Allowed

The Correct Pattern

All [type of code] MUST use [correct approach]:

// Import the helper
use [module]::[helper];

fn test_[feature]() {
    // Create test context using the helper
    let context = [helper]();

    // Create entities/resources as needed for THIS test
    let resource = [Resource]::new("[name]")
        .with_property("[key]", [value]);

    // Test the feature
    assert!(context.[feature_works](resource));
}

Why This Matters

If [constrained code] assumes [specific things]:

1. [Consequence 1]
2. [Consequence 2]
3. [Consequence 3]
4. [Overall impact]

This requirement must survive context compaction. It is non-negotiable.
