Claude Code QA agent with memory, plus a read-only MCP server (verdict-qa-mcp on PyPI): baseline → delta runs (NEW/REGRESSED), a fact harness so the model judges while the system measures, signed run history, flaky quarantine with expiry, and an exit-code release gate for CI. Ships six scored eval fixtures — misses published.
Trust what you ship: download and verify browser extension artifacts (zip structure, manifest, metadata) and emit a deterministic JSON report for CI release gates.
