v6.0.0

- Introduced a detailed guide on query filters in the README, covering basic filtering, comparison operators, array operators, logical operators, element operators, and advanced filtering patterns.
- Implemented a type-safe filtering system in `classes.doc.ts` with `MongoFilterCondition` and `MongoFilter` types to support MongoDB operators while maintaining nested type safety.
- Enhanced error handling for invalid operators and conditions in the filtering logic.
- Added extensive tests for various filtering scenarios, including basic, comparison, array, logical, and complex filters, ensuring robust functionality and performance.
- Implemented security measures to prevent the use of dangerous operators like `$where` and validate operator usage.

+# Changelog
+
+## 2025-11-17 - 6.0.0 - BREAKING CHANGE(decorators)
+Migrate to TC39 Stage 3 decorators and refactor decorator metadata handling; update class initialization, lucene adapter fixes and docs
+
+- Switch all decorators to TC39 Stage 3 signatures and metadata usage (use context.metadata and context.addInitializer) — affects svDb, globalSvDb, searchable, unI, index, Collection and managed.
+- Refactor Collection/managed decorators to read and initialize prototype/constructor properties from context.metadata to ensure prototype properties are available before instance creation (ts/classes.collection.ts).
+- Improve search implementation: add a Lucene parser and transformer with safer MongoDB query generation, wildcard/fuzzy handling and properly structured boolean operators (ts/classes.lucene.adapter.ts).
+- Search integration updated to use the new adapter and handle advanced Lucene syntax and edge cases more robustly.
+- Bump dev tooling versions: @git.zone/tsbuild -> ^3.1.0 and @git.zone/tsrun -> ^2.0.0.
+- Documentation: update README and add readme.hints.md describing the TC39 decorator migration, minimum TypeScript (>=5.2) and Deno notes; tests adjusted accordingly.
+- Clean up project memory/config files related to the previous decorator approach and Deno configuration adjustments.
+
+## 2025-11-17 - 5.16.7 - fix(classes.collection)
+Improve Deno and TypeScript compatibility: Collection decorator _svDbOptions forwarding and config cleanup
+
+- Collection decorator: capture original constructor and forward _svDbOptions to ensure property decorator options (serialize/deserialize) remain accessible in Deno environments.
+- Collection decorator: keep instance getter defined on prototype for Deno compatibility (no behavior change, clarifies forwarding logic).
+- Build/config: removed experimentalDecorators and useDefineForClassFields from deno.json and tsconfig.json to avoid Deno/TS build issues and rely on default compilation settings.
+
+## 2025-11-17 - 5.16.6 - fix(classes)
+Add Deno compatibility, prototype-safe decorators and safe collection accessor; bump a few deps
+
+- Add deno.json to enable experimentalDecorators and target ES2022/DOM for Deno builds.
+- Introduce getCollectionSafe() on SmartDataDbDoc and use it for save/update/delete/findOne to avoid runtime errors when instance 'collection' is not present.
+- Change several instance properties (globalSaveableProperties, uniqueIndexes, regularIndexes, saveableProperties) to 'declare' so decorator-set prototype properties are not shadowed (Deno compatibility).
+- Enhance @Collection decorator: capture original constructor/prototype for Deno, define prototype getter for collection on decorated class, attach docCtor for searchableFields, and forward _svDbOptions to the original constructor to preserve serializer metadata.
+- Improve text/search index handling by relying on docCtor.searchableFields and guarding text index creation.
+- Bump dependencies/devDependencies: @push.rocks/smartmongo -> ^2.0.14, @git.zone/tsbuild -> ^2.7.1, @git.zone/tstest -> ^2.8.1.
+- These are non-breaking runtime compatibility and developer-experience fixes; intended as a patch release.
+
+## 2025-11-16 - 5.16.5 - fix(watcher)
+Update dependencies, tooling and watcher import; add .serena cache ignore
+
+- Bump runtime dependencies: @push.rocks/smartlog 3.1.8 → 3.1.10, @push.rocks/smartstring 4.0.15 → 4.1.0, @push.rocks/taskbuffer 3.1.7 → 3.4.0, @tsclass/tsclass 9.2.0 → 9.3.0, mongodb 6.18.0 → 6.20.0
+- Bump devDependencies: @git.zone/tsbuild 2.6.7 → 2.6.8, @git.zone/tsrun 1.2.44 → 1.6.2, @git.zone/tstest 2.3.5 → 2.6.2
+- Switch EventEmitter import to node:events in ts/classes.watcher.ts to use the namespaced Node import
+- Add .serena/.gitignore to ignore /cache
+
+## 2025-08-18 - 5.16.4 - fix(classes.doc (convertFilterForMongoDb))
+Improve filter conversion: handle logical operators, merge operator objects, add nested filter tests and docs, and fix test script
+
+- Fix package.json test script: remove stray dot in tstest --verbose argument to ensure tests run correctly
+- Enhance convertFilterForMongoDb in ts/classes.doc.ts to properly handle logical operators ($and, $or, $nor, $not) and return them recursively
+- Merge operator objects for the same field path (e.g. combining $gte and $lte) to avoid overwriting operator clauses when object and dot-notation are mixed
+- Add validation/guards for operator argument types (e.g. $in, $nin, $all must be arrays; $size must be numeric) and preserve existing behavior blocking $where for security
+- Add comprehensive nested filter tests in test/test.filters.ts to cover deep nested object queries, $elemMatch, array size, $all, $in on nested fields and more
+- Expand README filtering section with detailed examples for basic filtering, deep nested filters, comparison operators, array operations, logical and element operators, and advanced patterns
+
+## 2025-08-18 - 5.16.3 - fix(docs)
+Add local Claude settings and remove outdated codex.md
+
+- Added .claude/settings.local.json to store local Claude/assistant permissions and configuration.

+
+## 2025-08-18 - 5.16.2 - fix(readme)
+Update README: clarify examples, expand search/cursor/docs and add local Claude settings
+

+- Expanded documentation for search, cursors, change streams, distributed coordination, transactions and EasyStore with more concrete code examples
+- Adjusted code examples to show safer defaults (ID generation, status/tags, connection pooling) and improved best-practices guidance
+- Added .claude/settings.local.json to provide local assistant/CI permission configuration
+
+## 2025-08-12 - 5.16.1 - fix(core)

+# Project Memory - Smartdata
+
+## TC39 Decorator Migration (v6.0.0) - ✅ COMPLETED
+
+### Final Status: All Tests Passing (157/157)
+Migration successfully completed on 2025-11-17.
+
+### What Changed:
+- ✅ Removed `experimentalDecorators` from tsconfig.json
+- ✅ Refactored all 7 decorators to TC39 Stage 3 syntax
+  - 5 property decorators: @globalSvDb, @svDb, @unI, @index, @searchable
+  - 2 class decorators: @Collection, @managed
+- ✅ Implemented context.metadata pattern for shared decorator state
+- ✅ All tests passing across Node.js and Deno runtimes
+
+### Critical Discovery: TC39 Metadata Access Pattern
+**THE KEY INSIGHT**: In TC39 decorators, metadata is NOT accessed via `constructor[Symbol.metadata]`. Instead:
+- **Field decorators**: Write to `context.metadata`
+- **Class decorators**: Read from `context.metadata` (same shared object!)
+- The `context.metadata` object is shared between all decorators on the same class
+- Attempting to write to `constructor[Symbol.metadata]` throws: "Cannot assign to read only property"
+
+### Implementation Pattern:
+```typescript
+// Field decorator - stores metadata
+export function svDb() {
+  return (value: undefined, context: ClassFieldDecoratorContext) => {
+    const metadata = context.metadata as ISmartdataDecoratorMetadata;
+    if (!metadata.saveableProperties) {
+      metadata.saveableProperties = [];
+    }
+    metadata.saveableProperties.push(String(context.name));
+  };
+}
+
+// Class decorator - reads metadata and initializes prototype
+export function Collection(dbArg: SmartdataDb) {
+  return function(value: Function, context: ClassDecoratorContext) => {
+    const metadata = context.metadata as ISmartdataDecoratorMetadata;
+    if (metadata?.saveableProperties) {
+      decoratedClass.prototype.saveableProperties = [...metadata.saveableProperties];
+    }
+    return decoratedClass;
+  };
+}
+```
+
+### Runtime Compatibility:
+- ✅ **Node.js v23.8.0**: Full TC39 support
+- ✅ **Deno v2.5.4**: Full TC39 support
+- ❌ **Bun v1.3.0**: No TC39 support (uses legacy decorators only)
+  - Removed "+bun" from test filenames to skip Bun tests
+
+### Key Technical Notes:
+1. **Metadata Initialization Timing**: Class decorators run AFTER field decorators, allowing them to read accumulated metadata and initialize prototypes before any instances are created
+2. **Prototype vs Instance Properties**: Properties set on prototype are accessible via `this.propertyName` in instances
+3. **TypeScript Lib Support**: TypeScript 5.9.3 includes built-in decorator types (no custom lib configuration needed)
+4. **Interface Naming**: Used `ISmartdataDecoratorMetadata` extending `DecoratorMetadataObject` for type safety
+
+### Files Modified:
+- ts/classes.doc.ts (property decorators + metadata interface)
+- ts/classes.collection.ts (class decorators + prototype initialization)
+- tsconfig.json (removed experimentalDecorators flag)
+- test/*.ts (renamed files to remove "+bun" suffix)
+
+### Test Results:
+All 157 tests passing across 10 test files:
+- test.cursor.ts: 7/7
+- test.deno.ts: 11/11 (queries working correctly!)
+- test.search.advanced.ts: 41/41
+- test.typescript.ts: 4/4
+- test.watch.ts: 5/5
+- And 5 more test files
+
+### Migration Learnings for Future Reference:
+1. `context.metadata` is the ONLY way to share state between decorators
+2. Class decorators must initialize prototypes from metadata immediately
+3. `Symbol.metadata` on constructors is read-only (managed by runtime)
+4. Field decorators run before class decorators (guaranteed order)
+5. TypeScript 5.2+ has built-in TC39 decorator support
