v7.1.0

- 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.

-# Code Style & Conventions
-
-## TypeScript Standards
-- **Target**: ES2022
-- **Module System**: ESM with NodeNext resolution
-- **Decorators**: Experimental decorators enabled
-- **Strict Mode**: Implied through TypeScript configuration
-
-## Naming Conventions
-- **Interfaces**: Prefix with `I` (e.g., `IUserData`, `IConfig`)
-- **Types**: Prefix with `T` (e.g., `TResponseType`, `TQueryResult`)
-- **Classes**: PascalCase (e.g., `SmartdataDb`, `SmartDataDbDoc`)
-- **Files**: All lowercase (e.g., `classes.doc.ts`, `plugins.ts`)
-- **Methods**: camelCase (e.g., `findOne`, `saveToDb`)
-
-## Import Patterns
-- All external dependencies imported in `ts/plugins.ts`
-- Reference as `plugins.moduleName.method()`
-- Use full import paths for internal modules
-- Maintain ESM syntax throughout
-
-## Class Structure
-- Use decorators for MongoDB document definitions
-- Extend base classes (SmartDataDbDoc, SmartDataDbCollection)
-- Static methods for factory patterns
-- Instance methods for document operations
-
-## Async Patterns
-- Preserve Promise-based patterns
-- Use async/await for clarity
-- Handle errors appropriately
-- Return typed Promises
-
-## MongoDB Specifics
-- Use `@unify()` decorator for unique fields
-- Use `@svDb()` decorator for database fields
-- Implement proper serialization/deserialization
-- Type-safe query construction with DeepQuery<T>
-
-## Testing Patterns
-- Import from `@git.zone/tstest/tapbundle`
-- End test files with `export default tap.start()`
-- Use descriptive test names
-- Cover edge cases and error conditions

 # Changelog
 
+## 2026-02-26 - 7.1.0 - feat(config)
+normalize npmextra.json to namespaced keys and add CI/release configuration
+
+- Replaced legacy keys (npmdocker, npmci, gitzone, tsdoc) with namespaced package keys (@git.zone/cli, @git.zone/tsdoc, @git.zone/tsdocker, @ship.zone/szci).
+- Moved tsdoc legal text under @git.zone/tsdoc.
+- Added release configuration with registries (https://verdaccio.lossless.digital and https://registry.npmjs.org) and accessLevel public under @git.zone/cli.
+- Added @git.zone/tsdocker CI/docker settings and @ship.zone/szci npm registry/tooling settings.
+- Removed old top-level entries to consolidate tooling configuration under scoped keys.
+
+## 2026-02-26 - 7.0.16 - fix(mongodb)
+set default socketTimeoutMS to 30000ms in MongoClient options to prevent hung operations from holding connections
+
+- Adds socketTimeoutMS: 30000 to MongoClient clientOptions in ts/classes.db.ts
+- Helps prevent hung operations from indefinitely holding connections by enforcing a 30s socket timeout
+- Non-breaking change (defaults only)
+
+## 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
+
+- Add initializeDecoratorMetadata helper to initialize prototype and constructor properties from TC39 decorator metadata
+- Refactor Collection and managed decorators to call initializeDecoratorMetadata with context.metadata
+- Remove direct reliance on constructor[Symbol.metadata] in class decorators to avoid read-only assignment issues
+- Ensure consistent initialization of saveableProperties, globalSaveableProperties, uniqueIndexes, regularIndexes, searchableFields and _svDbOptions
+
+## 2025-11-28 - 7.0.13 - fix(classes.doc)
+Remove noisy debug logging from decorators and serialization logic
+
+- Removed debug logger calls from globalSvDb decorator initialization
+- Removed debug logger calls from svDb decorator initialization and svDb options handling
+- Removed debug logger calls from unI and index decorator initializers
+- Removed debug logging in createSavableObject to reduce console noise; no functional changes
+
+## 2025-11-28 - 7.0.12 - fix(collection)
+Ensure TC39 decorator metadata is initialized on both original and decorated constructors/prototypes and add debug logging
+
+- Initialize metadata-driven prototype properties (globalSaveableProperties, saveableProperties, uniqueIndexes, regularIndexes) on both the decorated class prototype and the original constructor prototype to avoid closure/compatibility issues
+- Initialize searchableFields on both the decorated constructor and the original constructor so text-index creation and searches see the fields correctly
+- Forward and initialize _svDbOptions from decorator metadata onto the original constructor to preserve custom serialization options
+- Add debug logging in the Collection decorator and in createSavableObject to surface metadata and saveable-property counts for easier troubleshooting
+
+## 2025-11-28 - 7.0.9 - fix(classes.collection)
+Fix closure bug in Collection decorator by defining collection getter on original constructor and prototype
+
+- Define the collection getter on the original constructor so class-level references (e.g. `User.collection`) resolve to the decorated collection instead of the original constructor's closure value.
+- Also define the getter on the original constructor's prototype to ensure instance access works consistently across runtimes (Deno/Node).
+
+## 2025-11-28 - 7.0.8 - fix(classes.collection)
+Fix closure issue in managed decorator so Class.collection/instance.collection resolve correctly
+
+- Resolve closure bug in the managed() decorator where class methods referencing Class.collection (or instance.collection) could receive the original constructor's captured value and thus the wrong collection/manager.
+- Define dynamic getters on the original constructor and its prototype that compute the collection from the proper manager/db at access time (supports direct manager objects, delayed manager factory functions, and fallback to defaultManager).
+- Getters are defined as non-enumerable and configurable to preserve compatibility with existing consumers.
+
+## 2025-11-28 - 7.0.7 - fix(decorators)
+Fix decorator metadata initialization and Lucene query transformation
+
+- Ensure TC39 decorator metadata is used to initialize prototype properties so decorators work reliably across runtimes (context.metadata / Symbol.metadata shim imported early).
+- Field and class decorators now populate and consume metadata for saveable properties, indexes and searchable fields so prototype initialization happens before instance creation.
+- Fix Lucene -> MongoDB transformer to produce correct $or/$and/$not structures and improve wildcard/fuzzy/range handling for search queries.
+- Improve collection initialization to auto-create compound text indexes from searchableFields and ensure index creation is idempotent.
+
+## 2025-11-28 - 7.0.6 - fix(classes.collection)
+Guard against missing collection before attaching document constructor in Collection decorator
+
+- Added a truthy check for `coll` before setting `(coll as any).docCtor` in the Collection decorator (ts/classes.collection.ts).
+- Prevents a potential TypeError when `collectionFactory.getCollection` returns null/undefined during decorator initialization.
+
+## 2025-11-28 - 7.0.5 - fix(package)
+Add package exports entry and remove legacy main/typings fields
+
+- Added an "exports" entry in package.json mapping "." to ./dist_ts/index.js to declare the package's ESM entrypoint.
+- Removed legacy "main" and "typings" fields from package.json.
+- Improves Node/module resolution and modern bundler compatibility by using the package exports field.
+
+## 2025-11-28 - 7.0.4 - fix(decorators)
+Add Symbol.metadata polyfill and import it at entry to ensure decorator metadata is available
+
+- Add ts/shim.ts: defines Symbol.metadata when missing (polyfill for TC39 Stage 3 decorator metadata).
+- Import './shim.js' at the very top of ts/index.ts so the polyfill runs before any decorator code or exports are evaluated.
+- Prevents runtime errors when decorators rely on Symbol.metadata and improves compatibility across runtimes/environments.
+
+## 2025-11-28 - 7.0.3 - fix(build)
+Bump devDependency @git.zone/tsbuild to ^3.1.2
+
+- Updated @git.zone/tsbuild in devDependencies from ^3.1.1 to ^3.1.2
+
+## 2025-11-28 - 7.0.2 - fix(collectionfactory)
+Simplify CollectionFactory.getCollection: remove unnecessary IIFE and instantiate collection only when dbArg is SmartdataDb
+
+- Remove redundant IIFE wrapper in getCollection for improved readability
+- Only create and cache a SmartdataCollection when dbArg is an instance of SmartdataDb
+- Avoid assigning undefined to the collections map by guarding instantiation and returning existing collection
+
+## 2025-11-27 - 7.0.1 - fix(build)
+Update build tooling and TypeScript compilation target
+
+- Bump devDependency @git.zone/tsbuild from ^3.1.0 to ^3.1.1.
+- Update tsconfig.json compiler target from ES2022 to ES2024 (affects emitted JS language level).
+
+## 2025-11-27 - 7.0.0 - BREAKING CHANGE(mongodb)
+Upgrade dependencies: bump mongodb to ^7.0.0 and @git.zone/tstest to ^3.1.3
+
+- Bump 'mongodb' dependency from ^6.20.0 to ^7.0.0 — major version upgrade; may introduce breaking API changes and require code updates or verification against the new driver.
+- Update devDependency '@git.zone/tstest' from ^2.8.1 to ^3.1.3 — test tooling updated.
+
+## 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.
+- Removed codex.md (project overview) — documentation file deleted.
+- No runtime/library code changes; documentation/configuration-only update, bump patch version.
+
+## 2025-08-18 - 5.16.2 - fix(readme)
+Update README: clarify examples, expand search/cursor/docs and add local Claude settings
+
+- Refined README wording and structure: clearer Quick Start, improved examples and developer-focused phrasing
+- 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

-# SmartData Project Overview
-
-This document provides a high-level overview of the SmartData library (`@push.rocks/smartdata`), its architecture, core components, and key features—including recent enhancements to the search API.
-
-## 1. Project Purpose
-- A TypeScript‑first wrapper around MongoDB that supplies:
-  - Strongly‑typed document & collection classes
-  - Decorator‑based schema definition (no external schema files)
-  - Advanced search capabilities with Lucene‑style queries
-  - Built‑in support for real‑time data sync, distributed coordination, and key‑value EasyStore
-
-## 2. Core Concepts & Components
-- **SmartDataDb**: Manages the MongoDB connection, pooling, and initialization of collections.
-- **SmartDataDbDoc**: Base class for all document models; provides CRUD, upsert, and cursor APIs.
-- **Decorators**:
-  - `@Collection`: Associates a class with a MongoDB collection
-  - `@svDb()`: Marks a field as persisted to the DB
-  - `@unI()`: Marks a field as a unique index
-  - `@index()`: Adds a regular index
-  - `@searchable()`: Marks a field for inclusion in text searches or regex queries
-- **SmartdataCollection**: Wraps a MongoDB collection; auto‑creates indexes based on decorators.
-- **Lucene Adapter**: Parses a Lucene query string into an AST and transforms it to a MongoDB filter object.
-- **EasyStore**: A simple, schema‑less key‑value store built on top of MongoDB for sharing ephemeral data.
-- **Distributed Coordinator**: Leader election and task‑distribution API for building resilient, multi‑instance systems.
-- **Watcher**: Listens to change streams for real‑time updates and integrates with RxJS.
-
-## 3. Search API
-SmartData provides a unified `.search(query[, opts])` method on all models with `@searchable()` fields:
-
-- **Supported Syntax**:
-  1. Exact field:value (e.g. `field:Value`)
-  2. Quoted phrases (e.g. `"exact phrase"` or `'exact phrase'`)
-  3. Wildcards: `*` (zero or more chars) and `?` (single char)
-  4. Boolean operators: `AND`, `OR`, `NOT`
-  5. Grouping: parenthesis `(A OR B) AND C`
-  6. Range queries: `[num TO num]`, `{num TO num}`
-  7. Multi‑term unquoted: terms AND’d across all searchable fields
-  8. Empty query returns all documents
-
-- **Fallback Mechanisms**:
-  1. Text index based `$text` search (if supported)
-  2. Field‑scoped and multi‑field regex queries
-  3. In‑memory filtering for complex or unsupported cases
-
-### New Security & Extensibility Hooks
-The `.search(query, opts?)` signature now accepts a `SearchOptions<T>` object:
-```ts
-interface SearchOptions<T> {
-  filter?: Record<string, any>;        // Additional MongoDB filter AND‑merged
-  validate?: (doc: T) => boolean;      // Post‑fetch hook to drop results
-}
-```
-- **filter**: Enforces mandatory constraints (e.g. multi‑tenant isolation) directly in the Mongo query.
-- **validate**: An async function that runs after fetching; return `false` to exclude a document.
-
-## 4. Testing Strategy
-- Unit tests in `test/test.search.ts` cover basic search functionality and new options:
-  - Exact, wildcard, phrase, boolean and grouping cases
-  - Implicit AND and mixed free‑term + field searches
-  - Edge cases (non‑searchable fields, quoted wildcards, no matches)
-  - `filter` and `validate` tests ensure security hooks work as intended
-- Advanced search scenarios are covered in `test/test.search.advanced.ts`.
-
-## 5. Usage Example
-```ts
-// Basic search
-const prods = await Product.search('wireless earbuds');
-
-// Scoped search (only your organization’s items)
-const myItems = await Product.search('book', { filter: { ownerId } });
-
-// Post‑search validation (only cheap items)
-const cheapItems = await Product.search('', { validate: p => p.price < 50 });
-```

+# 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
+
+## 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
