v5.0.2 (2026-03-11)

Zero-Dependency Brainstorm Server

Removed all vendored node_modules — server.js is now fully self-contained

• Replaced Express/Chokidar/WebSocket dependencies with zero-dependency Node.js server using built-in http, fs, and crypto modules
• Removed ~1,200 lines of vendored node_modules/, package.json, and package-lock.json
• Custom WebSocket protocol implementation (RFC 6455 framing, ping/pong, proper close handshake)
• Native fs.watch() file watching replaces Chokidar
• Full test suite: HTTP serving, WebSocket protocol, file watching, and integration tests

Brainstorm Server Reliability

• Auto-exit after 30 minutes idle — server shuts down when no clients are connected, preventing orphaned processes
• Owner process tracking — server monitors the parent harness PID and exits when the owning session dies
• Liveness check — skill verifies server is responsive before reusing an existing instance
• Encoding fix — proper <meta charset="utf-8"> on served HTML pages

Subagent Context Isolation

• All delegation skills (brainstorming, dispatching-parallel-agents, requesting-code-review, subagent-driven-development, writing-plans) now include context isolation principle
• Subagents receive only the context they need, preventing context window pollution
