🔱 Harness Engineering Mode

New in v2.3.3-harness — Transforms the skill from vibe-coding into structured 5-stage generation with machine-readable gates.

The Problem: Vibe Coding vs. Harness

Without Harness, the entire 3,967-line SKILL.md was loaded every time, AI jumped straight to code, and errors were only discovered after rendering. With Harness, context is loaded progressively, structure is locked before content, and gates run as Python scripts — not AI self-evaluation.
