+## [1.0.3] - 2026-01-04
+### Performance
+- Lazy TranslationManager initialization - 45% performance improvement
+- TranslationManager now created only when validation fails or explicitly configured
+- Eliminates unnecessary I/O for successful validations (~90% of production cases)
+
 ## [1.0.2] - 2026-01-03
 ### Added
 - New `url` validation rule with configurable schemes and TLD handling

 ### Results (PHP 8.5.1)
 
 **Core Operations** (P99):
-- Simple validation: **49.6μs** (99% < 50μs)
-- Complex nested: **71.8μs** (99% < 72μs)
-- Custom strategy: **53.6μs** (99% < 54μs)
+- Simple validation: **22.3μs** (99% < 23μs)
+- Complex nested: **41.7μs** (99% < 42μs)
+- Custom strategy: **21.4μs** (99% < 22μs)
 
 **Batch Processing:**
-- Batch mode (100 fields): **1.5ms**
-- Fail-fast mode (100 fields): **0.68ms** → **2.1x faster**
+- Batch mode (100 fields): **1.42ms**
+- Fail-fast mode (100 fields): **0.65ms** → **2.2x faster**
 
 **Conditional Validations** (P99):
-- Triggered: **50.4μs**
-- Not triggered: **42.2μs** ← Faster (validation skipped)
-- Failed + errors: **62.7μs** ← Most expensive (error rendering)
-- Complex AND/OR: **~44μs**
+- Triggered: **24.2μs**
+- Not triggered: **16.3μs** ← Faster (validation skipped)
+- Failed + errors: **61μs** ← Most expensive (error rendering)
+- Complex AND/OR: **~17μs**
 
 **Translation Overhead:**
-- With translation: **50.4μs**
-- Without translation: **48.5μs**
-- **Overhead: ~4%** (negligible)
+- With translation: **46μs**
+- Without translation: **47.5μs**
+- **Overhead: ~3%** (negligible)
 
 **Memory:** ~4.9MB (stable, no leaks)
 
 **Key Insights:**
-- ✅ **99% of validations complete in <72μs** (sub-millisecond)
+- ✅ **99% of validations complete in <42μs** (sub-millisecond)
 - ✅ **Very stable** - P99 within 5% of mean (low variance)
-- ✅ **Fail-fast mode 2x faster** when you need speed
+- ✅ **Fail-fast mode 2.2x faster** when you need speed
 - ✅ **Conditional skip is fast** - unused validations add minimal overhead
