-### 11. Why AutoPack for object serialization?
-
-**Decision:** Use AutoPack to convert arrays of objects into TypedArrays before postMessage transfer, providing 1.5-10x faster serialization than structuredClone.
-
-**Performance benchmarks (1M objects, Node.js):**
-
-| Object Type | structuredClone | AutoPack | Speedup |
-|-------------|-----------------|----------|---------|
-| Numeric (5 fields) | 2275ms | 698ms | **3.3x** |
-| String (2 fields) | 2150ms | 1283ms | **1.7x** |
-| Mixed (num+str+bool) | 2114ms | 863ms | **2.4x** |
-| Nested (2 levels) | 5010ms | 1709ms | **2.9x** |
-
-**When AutoPack is used:**
-
-- `autoPack: 'auto'` (default): Enabled when array has 50+ objects
-- `autoPack: true`: Always use, throws if data not compatible
-- `autoPack: false`: Never use, fallback to structuredClone
