# Feature Status

> **Generated file — do not edit by hand.** Produced by `tools/status-report.ts` from each page's `status:` front matter. To change a page's status, edit that page's `status:` field and regenerate with `npm run status:write`.

**Maturity levels:** `Stable` (frozen contract) · `Candidate` (feature-complete, under review) · `Draft` (still evolving) · `Deprecated` · `Reserved`. Defined in the [Versioning Policy](/versioning-and-stability/versioning.md). Non-normative pages are marked `Informative` and are not graded here.

**Totals:** 72 Candidate.
