Code review: Document quality issues and fix naming/import hygiene

[Copilot]

Performed comprehensive code review of ~4,925 LOC Go codebase. Identified architectural patterns, documented technical debt, and fixed immediate hygiene issues.

Documentation Added

• CODE_REVIEW.md: Technical review covering error handling patterns, concurrency, resource management, testing gaps, and platform-specific code
• REVIEW_SUMMARY.md: Executive summary with metrics and prioritized recommendations

Key Findings (Documented, Not Fixed)

High Priority:

• 16 logger.Fatal() calls prevent error recovery and testing
• 3 panic() calls in Windows platform code
• Single test file with minimal coverage
• Goroutines lack graceful shutdown mechanisms

Metrics:

• 176 proper error checks (good)
• 5 TODO comments in production code
• 0 security vulnerabilities (CodeQL clean)

Code Fixes

• Removed commented imports (cmd/main.go, pkg/wire/ipfs/wire.go)
• Fixed Go naming: free_locked() → freeLocked()
• Fixed typo: "fale" → "fake" in comment
• Updated .gitignore to exclude compiled binaries

Example Issue

// Before: Program termination on error
func NewFakeIPManager(network, script, db string) *FakeIPManager {
    _, ipNet, err := net.ParseCIDR(network)
    if err != nil {
        logger.Fatal(err)  // Cannot recover or test
    }
    // ...
}

// Recommended: Return error for caller handling
func NewFakeIPManager(network, script, db string) (*FakeIPManager, error) {
    _, ipNet, err := net.ParseCIDR(network)
    if err != nil {
        return nil, errors.WithStack(err)
    }
    // ...
}

Review document provides specific recommendations for production readiness.
