# Architecture ## Config Resolution Skill support two mode: **clean architecture** (default) and **custom architecture** (team-define). Mode determine which rule load. **Step 1 — Determine mode:** 1. Read `.lattice/config.yaml` in repo root 2. Check `architecture_mode` key - If `architecture_mode: custom` → **custom mode** - If absent, or other value → **clean architecture mode** (default) **Step 2 — Load enforce rule:** - **Clean architecture mode** → Read `./references/clean-architecture.md` for enforce instruction (Self-Validation Checklist, Anti-Pattern Scan, Ambiguity Signals, structural principles) - **Custom mode** → Read `./references/custom-architecture.md` for enforce instruction **Step 3 — Load architecture content:** - **Clean architecture mode:** 1. Check `paths.architecture` in `.lattice/config.yaml` for custom doc 2. If found, read doc and check YAML frontmatter for `mode`: - **`mode: overlay`**: Read `./references/clean-architecture-defaults.md` first, then apply custom doc section on top. Section match by heading — custom section replace matching default, new section append. - **`mode: override`**: Custom doc take full precedence. Must be comprehensive. 3. If no custom doc → read `./references/clean-architecture-defaults.md` - **Custom mode:** 1. Check `paths.architecture` in `.lattice/config.yaml` for team architecture doc 2. If found → read it. Sole reference — no default. 3. If not found → surface: "No architecture docu...
