-## PR-00.2 — Extrair `prometeu-vm` do `prometeu-core`
-
-**Branch:** `pr-00-2-prometeu-vm`
-
-### Objetivo
-
-Mover `virtual_machine/*` para `crates/prometeu-vm/`.
-
-### Passos prescritivos
-
-1. Criar crate `crates/prometeu-vm/`.
-2. Mover `crates/prometeu-core/src/virtual_machine/**` → `crates/prometeu-vm/src/**`.
-3. Ajustar `use` paths em todos os crates.
-4. Adicionar shim temporário no `prometeu-core` (se ainda existir):
-
-    * `pub mod virtual_machine { pub use prometeu_vm::*; }`
-
-### Critérios de aceite
-
-* `cargo test` verde.
-* runtime desktop ainda roda.
