## [Unreleased]

### Status: 🚀 DEPLOYED & LIVE

All Wave 1-3 features are published to npm and integrated in production (next-js-app example).

#### Wave 5.4: Boolean/Number/String Variant Type Safety (v5.0.18+ ✅ JULY 4, 2026)

- **Fixed: Variant Type Enforcement in `defaultVariants` and Props** ✅
  - **Problem:** TypeScript now correctly enforces type matching between variant keys and `defaultVariants` values
  - **Impact:** 20 `styles.ts` files + 3+ `page.tsx` files in example app had string `"false"` in boolean variant defaults, or passed string `"true"`/`"false"` to boolean props
  - **What changed:** Example code updated to match correct types:
    ```typescript
    // Before (now errors)
    defaultVariants: { active: "false" }           // ❌ String
    <Chip active={isOpen ? "true" : "false"} />    // ❌ Strings
    
    // After (correct)
    defaultVariants: { active: false }              // ✅ Boolean
    <Chip active={isOpen} />                        // ✅ Boolean
    ```
  - **Type Safety Matrix:**
    ```
    Variant Keys              | Type   | defaultVariants | Usage
    { true: "...", false: "" }| bool   | active: false   | <C active={bool} />
    { 0: "...", 1: "..." }    | num    | level: 1        | <C level={num} />
    { "x": "...", "y": "" }   | str    | mode: "x"       | <C mode="string" />
    ```
  - **Steering Guide:** New `.kiro/steering/boolean-variants.md` documents:
    - Type matching rules (boolean, number, string)
    - Common mistakes and fixes
    - Migration patterns
    - Pre-shipping checklist
  - **Affected files fixed:**
    - 20 styles.ts: Changed `"false"` → `false` in defaultVariants
    - 3+ page.tsx: Changed string ternaries to boolean expressions
    - Specific files: All `learn/*/styles.ts` + css-functions-future, container-style-queries, popover-api
  - **Validation:** `examples/next-js-app tsc --noEmit` → 0 errors ✅
  - **Reference:** `known-issues.md` (2026-07-04 boolean variants entry), `.kiro/steering/boolean-variants.md` ⭐ (NEW)

#### Wave 5.3: TypeScript Props Type Inference Fix (v5.0.18+ ✅ JULY 4, 2026)

- **Fixed: `RuntimeProps` Type Now Supports All HTML Attributes (ARIA, data-*, event handlers, etc.)** ✅
  - **Problem:** Passing `role`, `aria-label`, `aria-selected`, `onClick`, `data-*`, and other standard HTML attributes to `tw.*` components resulted in TypeScript errors `Property 'X' does not exist on type...`
  - **Root cause:** `RuntimeProps<TConfig>` was not tag-specific — all `tw.button`, `tw.input`, `tw.div` used identical prop types, ignoring React's built-in tag-specific attribute inference
  - **Solution:** Added `Tag extends React.ElementType` generic parameter to `RuntimeProps`, then use `React.ComponentPropsWithoutRef<TTag>` to dynamically extract all valid props for the actual HTML tag
    ```typescript
    // Before: Generic, ignored tag-specific attributes
    type RuntimeProps<TConfig> = InferVariantProps<TConfig> & React.HTMLAttributes<HTMLElement>
    
    // After: Tag-specific, includes all native HTML props
    type RuntimeProps<TConfig, TTag extends React.ElementType> = 
      InferVariantProps<TConfig> & React.ComponentPropsWithoutRef<TTag>
    ```
  - **Impact:** All HTML attributes now work — ARIA attributes, data-attributes, event handlers with correct typings, tag-specific attributes (e.g. `href` on `<a>`, `value` on `<input>`)
  - **Validated:** `npm run build:packages` ✅, `examples/next-js-app tsc --noEmit` ✅, real component usage with ARIA in `aria-dynamic-theme/` example ✅
  - **Reference:** `packages/domain/core/src/createComponent.ts` (lines 219-225), `known-issues.md` (2026-07-04 entry)

#### Wave 5.2: Complete Build-Time Magic Documentation (v5.0.17+ ✅ JULY 3, 2026)
