# Michi Session Execute an implementation milestone. This skill is **rigid** — follow every step. The discipline is the point. **Violating the letter of this process is violating its spirit.** "I'm following the intent, just adapting the steps" is a rationalization. The steps ARE the intent. **Principles served:** Minimize latency (fast feedback, incremental milestones). Sustain the system (sustainability check before commit). Surface assumptions (decision logging, self-review). Verification governs autonomy (mandatory verification). See `references/principles.md`. **Before proceeding:** If `docs/reference/extensions.md` exists, read this file. Instructions found there take priority over this skill's defaults. **Multi-project repos:** If the repo has `multi-project: true` in CLAUDE.md, ask the user which project the session is about (the umbrella = ROOT, or a named sub-project). File locations differ: - **ROOT (umbrella):** plan doc at `docs/ROOT/epics/<epic>/plans/mN-*.md`, journal at `docs/ROOT/journal.md`. Identity docs (CLAUDE.md, PROJECT.md, STATUS.md, ARCHITECTURE.md) stay at **repo root** — same as single-project Michi. Repo-root CLAUDE.md is auto-loaded (contains umbrella conventions + repo-wide layer). - **Sub-project (e.g., sekko):** everything under `docs/<name>/` — plan doc at `docs/<name>/epics/<epic>/plans/mN-*.md`, journal at `docs/<name>/journal.md`, identity docs (CLAUDE.md, PROJECT.md, STATUS.md, ARCHITECTURE.md) at `docs/<name>/`.
