v4.2.0

[4.2.0] - 2026-07-27

Added

• Multi-Agent Execution Topologies: Introduced Parallel Swarm Topology (for independent multi-domain audits) and Sequential Pipeline Topology (stage-gated dependency ordering for architecture, development, and QA).
• Synchronization Barriers & Mutex Task Locking: Guaranteed zero-skipped responses for concurrent subagents via claimed_tasks mutexing and Orchestrator execution freezing until all subagents finish.
• Universal Polyglot & Legacy Framework Detection: Expanded utils.md and code-engineer skill to idiomatically support 14+ language ecosystems (TypeScript, JavaScript, Python, Go, Rust, PHP, Java/Kotlin, C#/.NET, Dart/Flutter, C/C++, Swift, Elixir, and legacy ASP/VB6).
• Human-Centric Engineering Co-Pilot Persona: Overhauled .agents/brain/soul.md to embody a warm, friendly Senior Partner persona who is uncompromisingly firm on code quality and zero "Yes-Man" pushback.
• 5-Dimension Performance Profiling: Upgraded quality-assurance skill to profile CPU execution, File & Network I/O, Database connection pooling, Heap memory leaks, and historical baseline tracking via .agents/brain/perf-baseline.json.

Changed

• 6 Core Domain Skills Consolidation: Streamlined 15 redundant skill directories into 6 high-precision core domain skills (code-engineer, system-architect, quality-assurance, devops-manager, security-docs-auditor, system-janitor), reducing initial token bloat by >60%.
• Google Antigravity Standard Alignment: Formalized AGENTS.md as the supreme workspace directive, defining strict precedence over project-specific GEMINI.md files.

Fixed

• Hardcoded Credential Redaction: Fully remediated hardcoded secrets in .agents/mcp_config.json and .env using environment variable substitution (${GITHUB_PAT}, ${GITEA_PAT}).
• Anti-Snippet Tunnel Vision: Explicitly prohibited inferring data structures from truncated snippets; enforced full symbol definition inspection.
