+# Changelog
+
+## 2025-12-11 - 6.2.3 - fix(watcher.node)
+Improve handling of temporary files from atomic editor writes in Node watcher
+
+- Detect temporary files produced by atomic editor saves and attempt to map them to the real target file instead of silently skipping the event
+- Add getTempFileTarget() to extract the real file path from temp filenames (supports patterns like file.ts.tmp.PID.TIMESTAMP and generic .tmp.*)
+- When a temp-file event is seen, queue a corresponding event for the resolved real file after a short delay (50ms) to allow rename/replace to complete
+- Add logging around temp file detection and real-file checks to aid debugging
+
+## 2025-12-11 - 6.2.2 - fix(watcher.node)
+Defer events during initial scan, track full event sequences, and harden watcher shutdown
+
+- Defer fs.watch events that arrive during the initial directory scan and process them after the scan completes to avoid race conditions where watchedFiles isn't populated.
+- Debounce now tracks the full sequence of events per file (rename/change) instead of collapsing to the last event, preventing intermediate events from being lost.
+- Detect delete+recreate via inode changes and emit unlink then add when appropriate; handle rapid create+delete sequences by emitting both events.
+- During stop(), cancel pending debounced emits before flipping _isWatching and make handleFsEvent return early when watcher is stopped to prevent orphaned timeouts and post-stop emits.
+- Add verbose logging of event sequences to aid debugging of complex fs event scenarios.
+- Update tests to expect unlink + add for inode replacement scenarios.
+- Version bump from 6.2.1 → 6.2.2
+
+## 2025-12-10 - 6.2.1 - fix(watcher.node)
+Handle fs.watch close without spurious restarts; add tests and improve test runner
+
+- Prevent spurious restarts and noisy warnings on fs.watch 'close' by checking the internal isWatching flag before logging and restarting (ts/watchers/watcher.node.ts).
+- Add comprehensive test suites covering basic operations, inode-change detection, atomic writes and stress scenarios (test/test.basic.ts, test/test.inode.ts, test/test.stress.ts).
+- Remove outdated test (test/test.ts) and delete the test asset test/assets/hi.txt.
+- Update test script in package.json to enable verbose logging, write a logfile and increase timeout to 120s to reduce flakiness in test runs.
+
+## 2025-12-10 - 6.2.0 - feat(watchers)
+Improve Node watcher robustness: file-level inode tracking, abortable restarts, restart race guards, and untracked-file handling
+
+- Add file-level inode tracking to detect delete+recreate (editor atomic saves) and emit correct 'change'/'add' events
+- Make restart delays abortable via AbortController so stop() cancels pending restarts and prevents orphan watchers
+- Guard against concurrent/dual restarts with restartingPaths to avoid race conditions between health checks and error handlers
+- Emit 'unlink' for deletions of previously untracked files (files created after initial scan) and clean up inode state
+- Track file inodes during initial scan and update/cleanup inode state on events
+- Improve logging for restart/inode/delete+recreate scenarios and update documentation/readme hints to v6.2.0+
+
+## 2025-12-08 - 6.1.1 - fix(watchers/watcher.node)
+Improve Node watcher robustness: inode tracking, ENOSPC detection, enhanced health checks and temp-file handling
+
+- Track directory inodes (watchedInodes) and restart watchers if inode changes are detected (addresses stale watchers when directories are replaced).
+- Health check now validates inode stability and explicitly detects ENOSPC (inotify max_user_watches) errors, emitting errors and logging a recommended fix command.
+- Detect ENOSPC in FSWatcher error events and log guidance to increase inotify limits.
+- Clear inode tracking state on watcher stop to avoid stale state across restarts.
+- Improve temporary file handling and logging to avoid dropping events for atomic writes (only skip pure temp files and log skipped temp events).
+- Documentation (readme.hints.md) updated with robustness notes, known fs.watch limitations, and example logs.
+
+## 2025-12-08 - 6.1.0 - feat(watcher.node)
+Add automatic restart, periodic health checks, and safe event emission to Node watcher; improve logging and stat handling
+
+- NodeWatcher: introduced safeEmit() to isolate subscriber errors and prevent watcher crashes
+- Auto-restart on failure with exponential backoff (1s → 30s) and up to 3 retry attempts per watched base path
+- Periodic health checks (every 30s) to detect missing watched paths and trigger automatic restarts
+- Handle unexpected FSWatcher 'close' events and restart watchers when they close silently
+- Verbose lifecycle logging with `[smartwatch]` prefix for start/stop/health/restart events
+- Clear restart tracking and stop health checks on watcher.stop() to ensure clean shutdown
+- Improved statSafe() to normalize followSymlinks logic and log non-ENO errors as warnings
+- Updated readme.hints.md documenting the new robustness features (v6.1.0+)
+
+## 2025-12-08 - 6.0.0 - BREAKING CHANGE(watchers)
+Replace polling-based write stabilization with debounce-based event coalescing and simplify watcher options
+
+- Remove polling-based WriteStabilizer (ts/utils/write-stabilizer.ts) and related waitForWriteFinish logic
+- Introduce debounce-based coalescing (debounceMs) for Node and Deno watchers (ts/watchers/watcher.node.ts, ts/watchers/watcher.deno.ts)
+- Change IWatcherOptions: remove stabilityThreshold/pollInterval/maxWaitTime and add debounceMs
+- Default watcher options updated to use debounceMs = 100
+- Node/Deno watchers now skip editor temp files earlier, debounce duplicate events, and emit events directly (no size polling)
+- Updated default watcher creation in Smartwatch to pass debounceMs
+- Update package.json build script to run 'tsbuild tsfolders'
+
+## 2025-12-08 - 5.1.0 - feat(watchers)
+Improve write stabilization and ignore temporary editor files
+
+- Add maxWaitTime option (ms) to IWatcherOptions and WriteStabilizer to cap how long stabilization will wait (default: 1000ms).
+- WriteStabilizer: reduce default stabilityThreshold from 300ms to 100ms and track write start time to enforce maxWaitTime and avoid indefinite polling.
+- Node and Deno watchers: detect and ignore common temporary/editor files (e.g. *.tmp.*, *.swp, *.swx, trailing ~, .#*) to prevent spurious events from atomic saves.
+- Node watcher: treat rename (atomic-save) events as already-complete files and emit add/change immediately without stabilization.
+- Deno watcher: use the configured maxWaitTime and polling-based stabilization for modify events to ensure consistent behavior across runtimes.
+
+## 2025-11-30 - 5.0.0 - BREAKING CHANGE(@push.rocks/smartwatch)
+Rename package and update branding/docs: switch from @push.rocks/smartchok to @push.rocks/smartwatch, update repository/homepage/bugs URLs and author, and refresh README examples and install instructions.
+
+- Package name changed from @push.rocks/smartchok to @push.rocks/smartwatch in package.json
+- Repository, homepage and issue URLs updated to point to the new smartwatch repository
+- Author changed to Task Venture Capital GmbH in package metadata
+- README updated: install commands, import examples and references now use @push.rocks/smartwatch
+- Documentation text and branding updated throughout README (project name, internal references)
+
+## 2025-11-30 - 4.0.1 - fix(readme)
+Update README: refine description and clarify trademark/legal information
+
+- Refined project description and tagline for clarity and brevity (adds lightweight wording and an emoji).
+- Updated Trademark section to explicitly mention third-party trademarks, add guidance about usage and approval, and clarify that trademarks are not covered by the MIT license.
+- Minor legal/company wording and formatting fixes (e.g. 'District Court' capitalization and contact sentence tweaks).
+- General README wording and formatting improvements for clearer instructions and feature descriptions.
+
+## 2025-11-30 - 4.0.0 - BREAKING CHANGE(watchers)
+Replace chokidar with native platform watchers and add cross-runtime support (Node.js, Deno, Bun); introduce write stabilization and internal glob matching
+
+- Replaced chokidar-based implementation with native file watching APIs (Node.js fs.watch, Deno.watchFs).
+- Added platform-specific watchers: NodeWatcher and DenoWatcher (Bun uses Node compatibility).
+- Implemented polling-based write stabilization (awaitWriteFinish replacement) to avoid duplicate events during writes.
+- Keep glob pattern support by matching events internally using picomatch; base-path extraction used to limit watch scope.
+- API/runtime requirement increased: Node.js >= 20.0.0 is required for native recursive fs.watch.
+- Package/documentation name and examples updated to @push.rocks/smartchok and export the Smartwatch class.
+
+## 2025-11-30 - 3.0.0 - BREAKING CHANGE(smartwatch)
+Introduce Smartwatch: cross-runtime native file watching for Node.js, Deno and Bun; rename smartchok to smartwatch and bump major version to 2.0.0
+
+- Rename public API and docs from Smartchok to Smartwatch and update package metadata for the new module name.
+- Replace chokidar with native watchers and picomatch-based glob filtering to enable cross-runtime support (Node.js, Deno, Bun).
+- Add watcher factory and runtime-specific implementations: watchers/index.ts, watcher.node.ts, watcher.deno.ts.
+- Add WriteStabilizer (ts/utils/write-stabilizer.ts) to provide awaitWriteFinish functionality via polling.
+- Introduce @push.rocks/smartenv for runtime detection and remove direct chokidar dependency; update dependencies accordingly.
+- Update tests (test/test.ts) and documentation (readme.md, readme.hints.md) to reflect API/name changes and new architecture.
+- Bump package version to 2.0.0 to mark breaking changes in API and behavior.
+
+## 2025-11-29 - 1.2.0 - feat(core)
+Migrate to chokidar 5.x, add picomatch filtering and update test/dev dependencies
+
+- Upgrade runtime dependencies: chokidar -> ^5.0.0 and picomatch -> ^4.0.3; bumped related @push.rocks packages versions.
+- Upgrade devDependencies: @git.zone/tsbuild, @git.zone/tsrun and @git.zone/tstest to newer v2/v3 releases; updated @types/node.
+- Updated README and readme.hints to document migration to chokidar 5.x and dev dependency changes.
+- Tests updated to use @git.zone/tstest/tapbundle (import change) and test runner start changed to export default tap.start().
+- Smartchok implementation updated to extract glob base paths, watch base directories and filter events via picomatch matchers (shouldWatchPath + event filtering).
+- Note: ts/00_commitinfo_data.ts still references chokidar 4.x in the description and should be updated to reflect the migration.
+
+## 2025-06-26 - 1.1.1 - fix(package.json)
+Add packageManager field to package.json for pnpm configuration
+
+- Added "packageManager": "pnpm@10.11.0+sha512.6540583f41cc5f628eb3d9773ecee802f4f9ef9923cc45b69890fb47991d4b092964694ec3a4f738a420c918a333062c8b925d312f42e4f0c263eb603551f977" to package.json
+
+## 2025-06-26 - 1.1.0 - feat(Smartchok)
+Migrate to chokidar 4.x with picomatch glob support, update documentation and tests
+
+- Removed deprecated @tempfix/watcher and added chokidar and picomatch as dependencies in package.json
+- Updated Smartchok class to extract base paths and apply custom glob filtering using picomatch
+- Revised readme and technical hints to reflect migration to chokidar 4.x and clarify glob pattern support

+# smartchok - Technical Hints
+
+## Native File Watching (v2.0.0+)
+
+The module now uses native file watching APIs instead of chokidar, providing cross-runtime support for Node.js, Deno, and Bun.
+
+### Exported Class
+
+The package exports the `Smartwatch` class (not `Smartchok`):
+```typescript
+import { Smartwatch } from '@push.rocks/smartchok';
+```
+
+### Architecture
+
+```
+ts/
+├── smartwatch.classes.smartwatch.ts   # Main Smartwatch class
+├── smartwatch.plugins.ts              # Dependencies (smartenv, picomatch, etc.)
+├── watchers/
+│   ├── index.ts                       # Factory with runtime detection
+│   ├── interfaces.ts                  # IWatcher interface and types
+│   ├── watcher.node.ts                # Node.js/Bun implementation (fs.watch)
+│   └── watcher.deno.ts                # Deno implementation (Deno.watchFs)
+└── utils/
+    └── write-stabilizer.ts            # awaitWriteFinish polling implementation
+```
+
+### Runtime Detection
+
+Uses `@push.rocks/smartenv` v6.x for runtime detection:
+- **Node.js/Bun**: Uses native `fs.watch()` with `{ recursive: true }`
+- **Deno**: Uses `Deno.watchFs()` async iterable
+
+### Dependencies
+
+- **picomatch**: Glob pattern matching (zero deps, well-maintained)
+- **@push.rocks/smartenv**: Runtime detection (Node.js, Deno, Bun)
+- **@push.rocks/smartrx**: RxJS Subject/Observable management
+- **@push.rocks/smartpromise**: Deferred promise utilities
+- **@push.rocks/lik**: Stringmap for pattern storage
+
+### Why picomatch?
+
+Native file watching APIs don't support glob patterns. Picomatch provides glob pattern matching with:
+- Zero dependencies
+- 164M+ weekly downloads
+- Excellent security profile
+- Full glob syntax support
+
+### Event Handling
+
+Native events are normalized to a consistent interface:
+
+| Node.js/Bun Event | Deno Event | Normalized Event |

+
+### awaitWriteFinish Implementation
+
+The `WriteStabilizer` class replaces chokidar's built-in write stabilization:
+- Polls file size until stable (configurable threshold: 300ms default)
+- Configurable poll interval (100ms default)
+- Handles file deletion during write detection
+
+### Platform Requirements
+
+- **Node.js 20+**: Required for native recursive watching on all platforms
+- **Deno**: Works on all versions with `Deno.watchFs()`
+- **Bun**: Uses Node.js compatibility layer
+
+### Robustness Features (v6.1.0+)
+
+The Node.js watcher includes automatic recovery mechanisms based on learnings from [chokidar](https://github.com/paulmillr/chokidar) and known [fs.watch issues](https://github.com/nodejs/node/issues/47058):
+
+**Auto-restart on failure:**
+- Watchers automatically restart when errors occur
+- Exponential backoff (1s → 30s max)
+- Maximum 3 retry attempts before giving up
+- **v6.2.0+**: Race condition guards prevent orphan watchers when `stop()` is called during restart
+
+**Inode tracking (critical for long-running watchers):**
+- `fs.watch()` watches the **inode**, not the path!
+- When directories are replaced (git checkout, atomic saves), the inode changes
+- Health check detects inode changes and restarts the watcher
+- **v6.2.0+**: File-level inode tracking detects delete+recreate (common editor save pattern)
+- This is the most common cause of "watcher stops working after some time"
+
+**Health check monitoring:**
+- 30-second periodic health checks
+- Detects when watched paths disappear
+- Detects inode changes (directory replacement)
+- Detects ENOSPC errors (inotify limit exceeded)
+- **v6.2.0+**: Protected against dual-restart race conditions (health check + error handler)
+
+**ENOSPC detection (Linux inotify limit):**
+- Detects when `/proc/sys/fs/inotify/max_user_watches` is exceeded
+- Logs fix command: `echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p`
+
+**Error isolation:**
+- Subscriber errors don't crash the watcher
+- All events emitted via `safeEmit()` with try-catch
+
+**Untracked file handling (v6.2.0+):**
+- Files created after initial scan are properly detected
+- Untracked file deletions emit `unlink` events instead of being silently dropped
+
+**Event Deferral During Initial Scan (v6.2.2+):**
+- Events are queued until initial scan completes
+- Prevents race conditions where events arrive before `watchedFiles` is populated
+- Deferred events are processed after scan completes
+
+**Event Sequence Tracking (v6.2.2+):**
+- Debounce now tracks ALL events in sequence, not just the last one
+- Prevents losing intermediate events (e.g., add→change→delete no longer loses add)
+- Intelligent processing of event sequences:
+  - Delete+recreate with inode change → emits `unlink` then `add`
+  - Rapid create+delete → emits both events
+  - Multiple changes → single `change` event (debouncing)
+
+**Post-Stop Event Guards (v6.2.2+):**
+- `handleFsEvent()` returns early if watcher is stopped
+- Pending emits are cleared BEFORE setting `_isWatching = false`
+- Prevents orphaned timeouts and events after `stop()`
+
+**Verbose logging:**
+- All lifecycle events logged with `[smartwatch]` prefix
+- Event sequences logged for debugging complex scenarios
+- Helps debug watcher issues in production
+
+Example log output:
+```
+[smartwatch] Starting watcher for 1 base path(s)...
+[smartwatch] Started watching: ./test/assets/
+[smartwatch] Starting health check (every 30s)
+[smartwatch] Watcher started with 1 active watcher(s)
+[smartwatch] Health check: 1 watchers active
+[smartwatch] Processing event sequence for ./src/file.ts: [rename, rename, change]
+[smartwatch] File inode changed (delete+recreate): ./src/file.ts
+[smartwatch]   Previous inode: 12345, current: 67890
+```
+
+### Known fs.watch Limitations
+
+1. **Watches inode, not path** - If a directory is replaced, watcher goes stale
+2. **inotify limits on Linux** - Default `max_user_watches` (8192) may be too low
+3. **No events for some atomic writes** - Some editors' save patterns may not trigger events
+4. **Platform differences** - Linux uses inotify, macOS uses FSEvents/kqueue
+
+### Testing
+
+```bash
+pnpm test
+```
+
+Tests verify:
+- Creating Smartwatch instance
+- Adding glob patterns
+- Receiving 'add' events for new files
+- Graceful shutdown

+🔍 **Glob Pattern Support** — Watch files using familiar patterns like `**/*.ts` and `src/**/*.{js,jsx}`
+📡 **RxJS Observables** — Subscribe to file system events using reactive streams
+🔄 **Dynamic Watching** — Add or remove watch patterns at runtime
+⚡ **Native Performance** — Uses `fs.watch()` on Node.js/Bun and `Deno.watchFs()` on Deno
+✨ **Write Stabilization** — Built-in debouncing prevents duplicate events during file writes
+🎯 **TypeScript First** — Full TypeScript support with comprehensive type definitions
+📦 **Minimal Footprint** — No chokidar, no FSEvents bindings — just ~500 lines of focused code
+
+## Usage
+
+### Basic Setup
+
+```typescript
+import { Smartwatch } from '@push.rocks/smartwatch';
+
+// Create a watcher with glob patterns
+const watcher = new Smartwatch([
+  './src/**/*.ts',           // Watch all TypeScript files in src
+  './public/assets/**/*'     // Watch all files in public/assets
+]);
+
+// Start watching
+await watcher.start();
+```
+
+### Subscribing to File Events
+
+Use RxJS observables to react to file system changes:
+
+```typescript
+// Get an observable for file changes
+const changeObservable = await watcher.getObservableFor('change');
+
+changeObservable.subscribe({
+  next: ([path, stats]) => {
+    console.log(`File changed: ${path}`);
+    console.log(`New size: ${stats?.size} bytes`);
+  },
+  error: (err) => {
+    console.error(`Error: ${err}`);
+  }
+});
+
+// Watch for new files
+const addObservable = await watcher.getObservableFor('add');
+addObservable.subscribe(([path]) => {
+  console.log(`File added: ${path}`);
+});
+
+// Watch for deleted files
+const unlinkObservable = await watcher.getObservableFor('unlink');
+unlinkObservable.subscribe(([path]) => {
+  console.log(`File deleted: ${path}`);
+});
+```
+
+### Supported Events
+
+| Event       | Description                    |
+|-------------|--------------------------------|
+| `add`       | File has been added            |
+| `addDir`    | Directory has been added       |
+| `change`    | File has been modified         |
+| `unlink`    | File has been removed          |
+| `unlinkDir` | Directory has been removed     |
+| `error`     | Error occurred                 |
+| `ready`     | Initial scan complete          |
+
+### Dynamic Watch Management
+
+Add or remove patterns while the watcher is running:
+
+```typescript
+const watcher = new Smartwatch(['./src/**/*.ts']);
+await watcher.start();
+
+// Add more patterns to watch
+watcher.add(['./tests/**/*.spec.ts', './config/*.json']);
+
+// Remove a pattern
+watcher.remove('./src/**/*.test.ts');
+```
+
+### Stopping the Watcher
+
+```typescript
+// Stop watching when done
+await watcher.stop();
+```
+
+### Complete Example
+
+```typescript
+import { Smartwatch } from '@push.rocks/smartwatch';
+
+async function watchProject() {
+  // Initialize with patterns
+  const watcher = new Smartwatch([
+    './src/**/*.ts',
+    './package.json'
+  ]);
+
+  // Start the watcher
+  await watcher.start();
+  console.log('👀 Watching for changes...');
+
+  // Subscribe to changes
+  const changes = await watcher.getObservableFor('change');
+  changes.subscribe(([path, stats]) => {
+    console.log(`📝 Modified: ${path}`);
+    console.log(`   Size: ${stats?.size ?? 'unknown'} bytes`);
+  });
+
+  // Subscribe to new files
+  const additions = await watcher.getObservableFor('add');
+  additions.subscribe(([path]) => {
+    console.log(`✨ New file: ${path}`);
+  });
+
+  // Subscribe to deletions
+  const deletions = await watcher.getObservableFor('unlink');
+  deletions.subscribe(([path]) => {
+    console.log(`🗑️ Deleted: ${path}`);
+  });
+
+  // Handle graceful shutdown
+  process.on('SIGINT', async () => {
+    console.log('\n🛑 Stopping watcher...');
+    await watcher.stop();
+    process.exit(0);
+  });
+}
+
+watchProject();
+```
+
+## How It Works
+
+smartwatch uses native file watching APIs for each runtime:
+
+| Runtime         | API Used                         |
+|-----------------|----------------------------------|
+| **Node.js 20+** | `fs.watch({ recursive: true })`  |
+| **Deno**        | `Deno.watchFs()`                 |
+| **Bun**         | Node.js compatibility layer      |
+
+### Under the Hood
+
+Native file watching APIs don't support glob patterns directly, so smartwatch handles pattern matching internally:
+
+1. **Base path extraction** — Extracts the static portion from each glob pattern (e.g., `./src/` from `./src/**/*.ts`)
+2. **Efficient watching** — Native watchers monitor only the base directories
+3. **Pattern filtering** — Events are filtered through [picomatch](https://github.com/micromatch/picomatch) matchers before emission
+4. **Event deduplication** — Built-in throttling prevents duplicate events from rapid file operations
+
+### Write Stabilization
+
+smartwatch includes built-in write stabilization (similar to chokidar's `awaitWriteFinish`). When a file is being written, events are held until the file size stabilizes, preventing multiple events for a single write operation.
+
+Default settings:
+- **Stability threshold**: 300ms
+- **Poll interval**: 100ms
+
+## Requirements
+
+| Runtime         | Version                                |
+|-----------------|----------------------------------------|
+| **Node.js**     | 20+ (required for native recursive watching) |
+| **Deno**        | Any version with `Deno.watchFs()` support |
+| **Bun**         | Uses Node.js compatibility             |
+
+## API Reference

+# Migration Plan: smartchok to Chokidar 4.x
+
+Command to reread CLAUDE.md: `cat /home/philkunz/.claude/CLAUDE.md`
+
+## MIGRATION COMPLETED ✅
+
+All phases of the migration have been successfully completed:
+
+## Current State Analysis
+
+- **Current dependency**: `@tempfix/watcher` v2.3.0 (a fork of fabiospampinato/watcher)
+- **Target**: Chokidar v4.0.3
+- **Major challenge**: Chokidar 4.x removed glob support, but smartchok heavily uses glob patterns
+
+## Migration Plan
+
+### Phase 1: Preparation
+1. Install chokidar 4.x and glob library for pattern matching
+   - `pnpm install chokidar@^4.0.3`
+   - `pnpm install picomatch` (for glob pattern matching)
+   - `pnpm uninstall @tempfix/watcher`
+
+### Phase 2: Code Changes
+
+#### 2.1 Update Plugin Imports (ts/smartchok.plugins.ts)
+- Remove `@tempfix/watcher` import
+- Add `chokidar` import
+- Add `picomatch` for glob pattern matching
+
+#### 2.2 Update Smartchok Class (ts/smartchok.classes.smartchok.ts)
+- Replace watcher initialization with chokidar
+- Implement custom glob filtering using picomatch
+- Update event mapping to match chokidar's event names
+- Adjust watcher options to match chokidar's API
+
+#### 2.3 Handle Glob Patterns
+Since chokidar 4.x removed glob support, we need to:
+- Parse glob patterns to extract base directories
+- Use chokidar to watch base directories
+- Use picomatch to filter events based on glob patterns
+- Ensure backward compatibility with existing API
+
+#### 2.4 Event Mapping
+Map chokidar events to existing smartchok events:
+- Keep existing event names for backward compatibility
+- Ensure all current functionality is preserved
+
+### Phase 3: Testing
+1. Run existing tests to ensure backward compatibility
+2. Add new tests for glob pattern handling
+3. Test edge cases with complex glob patterns
+4. Verify performance with large file sets
+
+### Phase 4: Documentation
+1. Update readme.md to reflect the change to chokidar 4.x
+2. Document any API changes (if any)
+3. Update version number in package.json
+
+## Technical Details
+
+### Key Differences to Handle:
+1. **Glob Support**: Implement custom glob filtering layer
+2. **API Changes**: Adapt initialization and option passing
+3. **Event Names**: Map between different event naming conventions
+4. **Minimum Node Version**: Ensure compatibility with Node 14+
+
+### Risk Mitigation:
+- Maintain backward compatibility with existing API
+- Extensive testing with current test suite
+- Consider keeping a legacy branch if breaking changes are unavoidable
