> **Kai root note:** `knowledge/`, `harness/`, and `scripts/` paths in this skill live in the Kai install, not the user's project. Resolve them against the first ancestor directory of this SKILL.md that contains a `knowledge/` folder (the Kai plugin root, `~/.claude/kai`, or the kai-cmo-harness repo). `MARKETING.md`, `memory/`, and any output files live in the current project. If a referenced `scripts/` command is not available in this install, say so, skip it, and continue with the file-based guidance — never fabricate its output. ## Objective The harness ends this cycle enforcing something it was only remembering at the start. Gate-failure logs and 30-day grades become diagnosed lessons; lessons that keep firing become lint rules, contract checks, or checklist lines with golden corpus cases behind them, and the memory index reflects what changed. Run it monthly, after any sprint that produced 5+ gated pieces, whenever the same gate failure appears twice in one session, or when a 30-day check grades new underperformers. Read `memory/MEMORY.md` first — the graduation ladder is the shape of the whole cycle. ## Done when Work type `harness-change` — floor **E3/C3/O1** (`harness/eco-floors.yaml`). - **E3** — `golden_check.py` passes on the changed tree and a named human approved the diff. Memory and gate changes commit together so the lesson and its enforcement read side by side. - **C3** — every promotion into a gate script has a matching case in `evals/golden/manifest.jso
