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>

# stack-trace
|
|
|
|
Get v8 stack traces as an array of CallSite objects.
|
|
|
|
## Install
|
|
|
|
``` bash
|
|
npm install stack-trace
|
|
```
|
|
|
|
## Usage
|
|
|
|
The stack-trace module makes it easy for you to capture the current stack:
|
|
|
|
``` javascript
|
|
var stackTrace = require('stack-trace');
|
|
var trace = stackTrace.get();
|
|
|
|
require('assert').strictEqual(trace[0].getFileName(), __filename);
|
|
```
|
|
|
|
However, sometimes you have already popped the stack you are interested in,
|
|
and all you have left is an `Error` object. This module can help:
|
|
|
|
``` javascript
|
|
var stackTrace = require('stack-trace');
|
|
var err = new Error('something went wrong');
|
|
var trace = stackTrace.parse(err);
|
|
|
|
require('assert').strictEqual(trace[0].getFileName(), __filename);
|
|
```
|
|
|
|
Please note that parsing the `Error#stack` property is not perfect, only
|
|
certain properties can be retrieved with it as noted in the API docs below.
|
|
|
|
## Long stack traces
|
|
|
|
stack-trace works great with [long-stack-traces][], when parsing an `err.stack`
|
|
that has crossed the event loop boundary, a `CallSite` object returning
|
|
`'----------------------------------------'` for `getFileName()` is created.
|
|
All other methods of the event loop boundary call site return `null`.
|
|

## API
|
|
|
|
### stackTrace.get([belowFn])
|
|
|
|
Returns an array of `CallSite` objects, where element `0` is the current call
|
|
site.
|
|
|
|
When passing a function on the current stack as the `belowFn` parameter, the
|
|
returned array will only include `CallSite` objects below this function.
|
|
|
|
### stackTrace.parse(err)
|
|
|
|
Parses the `err.stack` property of an `Error` object into an array compatible
|
|
with those returned by `stackTrace.get()`. However, only the following methods
|
|
are implemented on the returned `CallSite` objects.
|
|
|
|
* getTypeName
|
|
* getFunctionName
|
|
* getMethodName
|
|
* getFileName
|
|
* getLineNumber
|
|
* getColumnNumber
|
|
* isNative
|
|
|
|
Note: Except `getFunctionName()`, all of the above methods return exactly the
|
|
same values as you would get from `stackTrace.get()`. `getFunctionName()`
|
|
is sometimes a little different, but still useful.
|
|
|
|
### CallSite
|
|
|
|
The official v8 CallSite object API can be found [here][v8stackapi]. A quick
|
|
excerpt:
|
|
|
|
> A CallSite object defines the following methods:
|
|
>
|
|
> * **getThis**: returns the value of this
|
|
> * **getTypeName**: returns the type of this as a string. This is the name of the function stored in the constructor field of this, if available, otherwise the object's [[Class]] internal property.
|
|
> * **getFunction**: returns the current function
|
|
> * **getFunctionName**: returns the name of the current function, typically its name property. If a name property is not available an attempt will be made to try to infer a name from the function's context.
|
|
> * **getMethodName**: returns the name of the property of this or one of its prototypes that holds the current function
|
|
> * **getFileName**: if this function was defined in a script returns the name of the script
|
|
> * **getLineNumber**: if this function was defined in a script returns the current line number
|
|
> * **getColumnNumber**: if this function was defined in a script returns the current column number
|
|
> * **getEvalOrigin**: if this function was created using a call to eval returns a CallSite object representing the location where eval was called
|
|
> * **isToplevel**: is this a toplevel invocation, that is, is this the global object?
|
|
> * **isEval**: does this call take place in code defined by a call to eval?
|
|
> * **isNative**: is this call in native V8 code?
|
|
> * **isConstructor**: is this a constructor call?
