 All notable changes to Void 2.0 are documented here.
 Format: [Keep a Changelog](https://keepachangelog.com).
 
+## 2.0.0-alpha.21 — Docs-kind spaces + long-page embedding
+- **`spaces.kind` (`'project'` | `'docs'`)** (`migration 021`): `'docs'` spaces render as a pure documentation repository — `public/views/space.js` shows only the sectioned page tree (no Projects/Tasks/"+ New"), and the sidebar expands a docs space to its top-level pages (`#/page/:id`) instead of projects. The **Wiki** is seeded to `'docs'`. Project spaces unchanged.
+- **Chunk + mean-pool embeddings** (`lib/ai/ollama.js` `chunkText`/`embedTextPooled`, used by the embed worker): long pages are split into ≤1500-char chunks, each embedded, then element-wise mean-pooled into one vector — replacing the old `slice(0,6000)` truncation that made dense/long docs fail with Ollama "input length exceeds context length". Single-chunk docs are unchanged.
+
 ## 2.0.0-alpha.20 — Page ordering + sectioned space view
 - **Explicit page ordering** (`migration 020`, `lib/db/repos/pages.js`): pages gain a `position integer` column; `listBySpace` now orders `position, title` instead of alphabetical-only, with a covering index `(space_id, position, title)`. `position` is patchable via `PUT /api/pages/:id`. Backfills all rows to `0` (preserves prior title order until positions are set).
 - **Sectioned page tree** (`public/views/space.js`): the flat pages table is replaced by a `parent_id`-grouped tree — top-level pages render as section headers with their children/grandchildren nested. Backward-compatible with flat (un-nested) spaces. Enables the Wiki to read as ordered, sectioned documentation rather than an alphabetical dump.
