   - `wiki/_meta/` — naming conventions, style guide, cross-reference index
 - **Design principles:** (1) Game-first, not encyclopedia-first — every entry serves the content pipeline. (2) Hierarchical with cross-references via IDs, not file paths. (3) Metadata-rich YAML frontmatter enabling programmatic queries. (4) Template-driven — new entries follow category templates. (5) Every entry has a `status` field: `proposed` → `draft` → `canonical`.
 - **Governance:** Miri owns wiki structure (new categories, templates, structural decisions). Anyone can create entries within their domain following templates. Qatux maintains the index and cross-references.
