+
+### 7.4 Remaining Stubs (kept for bytecode backward compatibility)
+- JSAtom typedef (uint32_t) - used in BC serialization
+- JS_ATOM_NULL, JS_ATOM_END - bytecode format markers
+- JS_FreeAtom, JS_DupAtom - no-op stubs

 **Build: SUCCEEDS** with warnings (unused variables, labels)
 
 **Statistics:**
-- JS_ATOM_* usages: ~40 remaining (down from 171+)
+- JS_ATOM_* usages: Minimal (only BC serialization compat)
-- Most remaining are stub functions and debug code
+- Property access uses JS_KEY_* macros or JS_GetPropertyStr
+- BC_VERSION: 6 (updated for new key-based format)
 
 **What Works:**
+- All property access via JSValue keys
 - Keyword detection via string comparison
 - Function declaration parsing with JSValue names
 - Variable definition with JSValue names
-- Property access with JSValue keys
 - Closure variable tracking with JSValue names
 - VM opcode handlers read cpool indices and look up JSValue
 - resolve_scope_var() uses JSValue throughout
 - js_parse_property_name() returns JSValue
-
+- Bytecode serialization uses bc_put_key/bc_get_key for property keys
-**Next Priority:**
+- Variable opcodes use key format (cpool indices)
-1. Update bytecode serialization (Phase 6)
+- JSON parsing uses JSValue keys
-2. Final cleanup - remove JSAtom type completely (Phase 7)
+- Internal variable names use JS_KEY__ret_, JS_KEY__eval_, JS_KEY__var_
+- JS_SetPropertyFunctionList uses JSValue keys
+- JS_Invoke uses JSValue method keys
+- break/continue labels use JSValue

-After each sub-phase:
-1. `make` - verify compilation
-2. Run basic eval: `./cell -e "1+1"`
-3. Run property test: `./cell -e "var o = {a:1}; o.a"`
-4. Run function test: `./cell -e "(function f(x){return x*2})(3)"`
-5. Run closure test: `./cell -e "var f = (function(){var x=1;return function(){return x++}})(); f(); f()"`
