Verify build quality before shipping

Run 6-phase code quality gates

Confirm quality gates still pass after refactoring before opening a PR

• · working directory with build config

• · verification report: build/type/lint/test/security/diff status

• · npm
• · tsc
• · pytest
• · grep

Project has build, test, lint scripts configured

• · Stops at phase 1 if build fails
• · Type errors reported but non-blocking if critical ones fixed

• · 6-phase waterfall ensures build-first ordering
• · Security scan catches console.log leaks
