Code Review (Gate 4)

Overview

Dispatch all ten reviewer subagents in parallel for fast, comprehensive feedback:

1. ring:code-reviewer - Architecture, design patterns, code quality
2. ring:business-logic-reviewer - Domain correctness, business rules, edge cases
3. ring:security-reviewer - Vulnerabilities, authentication, OWASP risks
4. ring:test-reviewer - Test quality, coverage, edge cases, anti-patterns
5. ring:nil-safety-reviewer - Nil/null pointer safety for Go and TypeScript
6. ring:consequences-reviewer - Ripple effects, caller chain impact, downstream consequences
7. ring:dead-code-reviewer - Orphaned code detection, reachability analysis, dead dependency chains
8. ring:performance-reviewer - Performance hotspots, allocations, goroutine leaks, N+1 queries, infra misconfigurations
9. ring:multi-tenant-reviewer - Multi-tenant patterns from lib-commons/multitenancy, tenantId propagation, database isolation
10. ring:lib-commons-reviewer - Correct lib-commons package usage and reinvented-wheel opportunities

Core principle: All 10 reviewers run simultaneously in a single message with 10 Task tool calls.
