-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 `wiki-maintainer` skill enforces the workflow and file formats. This file overrides the skill where they conflict.
-
-## Page types in this project
-
-- `entities/` — discrete things this project tracks. Reserved for future use (individual skills if they accumulate non-obvious context, tools we adopt).
-- `concepts/` — design decisions, technical gotchas, refactor notes. Most pages live here.
-- `packages/` — currently empty. Would be used if we extract a package (e.g. a CLI) from this repo.
-- `summaries/` — one summary per ingested external doc; carries `ingested:` and `raw_path:` frontmatter.
-- `overview.md` — single project-wide overview. Read this first if new to the repo.
-
-## Naming
-
-- `kebab-case.md`, **Latin only**. Transliterate Cyrillic in filenames; keep the original title in the H1 + frontmatter.
-
-## Domain conventions
-
-- Skill-related design notes go in `concepts/<skill-name>-*.md` (e.g. `active-platform-decision.md`).
-- Build / install pipeline notes live in `concepts/build-*.md`.
-- Refactor / re-alignment commits get a `concepts/<what>-realignment.md` page.
-
-## Frontmatter
-
-Minimum:
-
-```yaml
----
-title: Human-readable title
-type: concept | entity | package | source | overview
-updated: YYYY-MM-DD
----
-```
-
-`source/` pages also carry `ingested:` and `raw_path:`.
+**Не читать. Не править.** Канон — mappa (`mcp__mappa__*`): wiki-сущности проекта, конвенции — AGENTS-сущность. Скил: `mappa-knowledge`.
