# Status of This Specification

**Meta-Universe v2.0 — Working Draft.**

This specification is a **Working Draft**. It is published for review,
experimentation and implementation feedback.

- **Do not cite it as a finalized normative standard yet.** Normative statements
  (`SHALL` / `SHOULD` / `MAY`) express intent and are stable in spirit, but
  wording, requirement IDs and document numbers MAY still change before the first
  stable release.
- **Per-document status** is recorded in each document's header (`Status:`) and,
  machine-readably, in [`spec-index.yaml`](spec-index.yaml).
- **Requirement identifiers** (e.g. `MUC-R03`) are generated and catalogued in
  [`REQUIREMENTS-INDEX.md`](REQUIREMENTS-INDEX.md); during the Working Draft phase
  they MAY be renumbered, and will be frozen at the first stable release.
- **Stability lifecycle:** 🟥 Planned → 🟧 Working Draft → 🟦 Draft → 🟩 Frozen / Stable.
  Changes follow the [Change Process](01-constitution/Change-Process.md) and the
  [Freeze Rule](README.md#freeze-rule).

What *is* already stable and machine-checked: the MUIF interchange format and the
Semantic Fingerprint algorithm, the JSON Schemas, the reference tools
(`tools/`), and the worked examples (`examples/`) — all verified by the
[Semantic Test Kit](tests/).
