Goals -- **Modernization:** Adopts Swift 6.0+ Parameter Packs. -- **Simplification:** Removes 1000s of lines of generated code. -- **Unified API:** Provides a single, variadic interface for `Family`, `Nexus`, and `Entity` operations. -- **Tooling:** Removes Sourcery dependency and build steps. - -## 3. Functional Requirements -### 3.1 Family & Nexus API -- **Replace:** `Family2`, `Family3`, etc., with a single `Family` type. -- **Update:** `Nexus.family(requires:)` to accept a parameter pack of component types. -- **Breaking Change:** Existing `FamilyN` type aliases will be removed. -- **Codable Support:** The new `Family` must support encoding and decoding of components (where `each Component: Codable`) to maintain feature parity. - -### 3.2 System & Entity API -- **Update:** `System` protocols to support variadic generic constraints for family requirements. -- **Update:** `Entity.assign(...)` and `Entity.create(...)` to accept variadic component arguments. - -### 3.3 Tooling -- **Remove:** `.sourcery.yml`, `.sourceryTests.yml`, and all `*.stencil` templates. -- **Remove:** `make generate-code` build step. - -## 4. Non-Functional Requirements -- **Language:** Swift 6.0+ -- **Performance:** While no specific benchmarks are required for this track, the implementation should aim to maintain existing performance characteristics where possible. - -## 5.
