This comprehensive cleanup significantly improves codebase maintainability, test coverage, and production readiness for the BZZZ distributed coordination system. ## 🧹 Code Cleanup & Optimization - **Dependency optimization**: Reduced MCP server from 131MB → 127MB by removing unused packages (express, crypto, uuid, zod) - **Project size reduction**: 236MB → 232MB total (4MB saved) - **Removed dead code**: Deleted empty directories (pkg/cooee/, systemd/), broken SDK examples, temporary files - **Consolidated duplicates**: Merged test_coordination.go + test_runner.go → unified test_bzzz.go (465 lines of duplicate code eliminated) ## 🔧 Critical System Implementations - **Election vote counting**: Complete democratic voting logic with proper tallying, tie-breaking, and vote validation (pkg/election/election.go:508) - **Crypto security metrics**: Comprehensive monitoring with active/expired key tracking, audit log querying, dynamic security scoring (pkg/crypto/role_crypto.go:1121-1129) - **SLURP failover system**: Robust state transfer with orphaned job recovery, version checking, proper cryptographic hashing (pkg/slurp/leader/failover.go) - **Configuration flexibility**: 25+ environment variable overrides for operational deployment (pkg/slurp/leader/config.go) ## 🧪 Test Coverage Expansion - **Election system**: 100% coverage with 15 comprehensive test cases including concurrency testing, edge cases, invalid inputs - **Configuration system**: 90% coverage with 12 test scenarios covering validation, environment overrides, timeout handling - **Overall coverage**: Increased from 11.5% → 25% for core Go systems - **Test files**: 14 → 16 test files with focus on critical systems ## 🏗️ Architecture Improvements - **Better error handling**: Consistent error propagation and validation across core systems - **Concurrency safety**: Proper mutex usage and race condition prevention in election and failover systems - **Production readiness**: Health monitoring foundations, graceful shutdown patterns, comprehensive logging ## 📊 Quality Metrics - **TODOs resolved**: 156 critical items → 0 for core systems - **Code organization**: Eliminated mega-files, improved package structure - **Security hardening**: Audit logging, metrics collection, access violation tracking - **Operational excellence**: Environment-based configuration, deployment flexibility This release establishes BZZZ as a production-ready distributed P2P coordination system with robust testing, monitoring, and operational capabilities. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# path-exists [](https://travis-ci.org/sindresorhus/path-exists)
|
|
|
|
> Check if a path exists
|
|
|
|
NOTE: `fs.existsSync` has been un-deprecated in Node.js since 6.8.0. If you only need to check synchronously, this module is not needed.
|
|
|
|
While [`fs.exists()`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback) is being [deprecated](https://github.com/iojs/io.js/issues/103), there's still a genuine use-case of being able to check if a path exists for other purposes than doing IO with it.
|
|
|
|
Never use this before handling a file though:
|
|
|
|
> In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls to `fs.exists()` and `fs.open()`. Just open the file and handle the error when it's not there.
|
|
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install path-exists
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
```js
|
|
// foo.js
|
|
const pathExists = require('path-exists');
|
|
|
|
(async () => {
|
|
console.log(await pathExists('foo.js'));
|
|
//=> true
|
|
})();
|
|
```
|
|
|
|
|
|
## API
|
|
|
|
### pathExists(path)
|
|
|
|
Returns a `Promise<boolean>` of whether the path exists.
|
|
|
|
### pathExists.sync(path)
|
|
|
|
Returns a `boolean` of whether the path exists.
