## Pattern Library (Coming Soon)

### Common Constraint Patterns

```
# Dependency constraints
IF [FeatureA] = "Enabled" THEN [FeatureB] = "Enabled";

# Exclusive options
IF [PaymentMethod] = "Cash" THEN [InstallmentPlan] = "None";

# Platform limitations
IF [OS] = "iOS" THEN [Browser] IN {Safari, Chrome};

# Environment restrictions
IF [Environment] = "Production" THEN [LogLevel] <> "Debug";
```

### Boundary Value Patterns

```
# Numeric boundaries
Age: 0, 17, 18, 64, 65, 100

# Size categories
FileSize: 0KB, 1KB, 1MB, 100MB, 1GB

# Time periods
Duration: 0s, 1s, 30s, 60s, 3600s
```

### Negative Testing Patterns

```
# Invalid inputs (using ~ prefix in some PICT variants)
Email: Valid, Invalid, Empty, TooLong
Password: Strong, Weak, Empty, SpecialChars

# Error conditions
NetworkStatus: Connected, Slow, Disconnected, Timeout
```
