 # Changelog
 
+## 2025-12-01 - 7.0.15 - fix(classes.doc)
+Avoid emitting instance fields for collection and manager to preserve decorator-defined prototype getters
+
+- ts/classes.doc.ts: changed instance properties `collection` and `manager` to `declare` so TypeScript does not emit them as own properties — prevents ES2022 class fields from shadowing prototype getters created by @Collection and @managed decorators.
+- readme.hints.md: added documentation explaining the ES2022 class fields issue and recommending use of `declare` for type-only instance properties; marks the fix as v7.0.15.
+
 ## 2025-11-28 - 7.0.14 - fix(classes.collection)
 Centralize TC39 decorator metadata initialization and use context.metadata in class decorators

+## ES2022 Class Fields & Prototype Getters - Fixed in v7.0.15
+
+### Issue
+ES2022 class fields (`useDefineForClassFields: true`) create own properties during construction that shadow prototype getters defined by decorators.
+
+### Solution
+Use `declare` keyword for instance properties that are accessed via prototype getters:
+```typescript
+// In SmartDataDbDoc (ts/classes.doc.ts):
+declare public collection: SmartdataCollection<any>;  // Type-only, no JS emitted
+declare public manager: TManager;  // Type-only, no JS emitted
+```
+
+### Key Insight
+- `declare` tells TypeScript this is a type-only declaration
+- No JavaScript code is emitted for `declare` properties
+- Prototype getters defined by `@Collection` and `@managed` decorators are no longer shadowed
