+# Wiki Schema — meeting-room
+
+Project-specific wiki conventions. Read this before any wiki operation.
+
+This wiki follows Karpathy's LLM Wiki pattern:
+**https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f**
+
+The `using-wiki` skill enforces the workflow and file formats. This file overrides the skill where they conflict.
+
+## Scope
+
+This wiki is **project-level** — for knowledge specific to the meeting-room project:
+- architecture decisions, backend design, UI patterns
+- entities like roles, providers, scenario format
+- concepts like brainstorm mode, roundtable mode, artifact generation
+
+For cross-project knowledge (org structure, shared conventions) use the global `~/projects/.wiki/`.
+
+## Page types
+
+- `entities/` — discrete things: roles, providers, config schema.
+- `concepts/` — recurring ideas, design decisions: brainstorm, roundtable, artifacts.
+- `packages/` — code packages this project produces or consumes.
+- `sources/` — one summary page per ingested external doc; carries `ingested:` and `raw_path:`.
+- `overview.md` — single project-wide overview.
+
+## Naming
+
+- `kebab-case.md`, **Latin only**. Transliterate Cyrillic in filenames; keep the original title in the H1 + frontmatter.
+
+## Domain conventions
+
+- Entities: roles (moderator, skeptic, idea_generator, analyst, boss, cso), providers (routerai, ollama_cloud)
+- Concepts: brainstorm (1:1 with CSO), roundtable (multi-agent discussion), setup (pre-discussion config), artifacts (tasks, wiki, decisions)
+- Packages: httpx, pyyaml (runtime); textual/fastapi (planned)
