 Rules of thumb:
 
 - **Local dev:** run nothing manually if hooks are installed. `make test-unit` on demand when you want a sanity check. Skip L2+ unless you're cutting a release.
 - **Before pushing:** `make test-unit` (the pre-push hook does this automatically). Requires `brew` / `git` / `npm` on PATH — they are queried read-only against temp dirs, no real installs.
-- **Before tagging a release (convention, not enforced):** `make test-vm` on an Apple Silicon Mac with Tart installed. See [VM E2E setup](#vm-e2e-setup) below. `auto-release.yml` opens a `release-ready` issue on `feat:` thresholds to nudge you here.

-# Tart VM e2e
-
-The `scripts/vm/run.sh` driver spins up an ephemeral Tart VM for the
-destructive e2e suite (`make test-vm`). The 12 test files in `test/e2e/`
-run inside it.
-
-## One-time setup
-
-Tart only runs on Apple Silicon Macs.
-
-```bash
-# 1. Install Tart (https://tart.run)
-brew install cirruslabs/cli/tart
-
-# 2. Pull the base image (downloads ~25GB)
-#    Canonical upstream:
-tart pull ghcr.io/cirruslabs/macos-tahoe-base:latest
-#    Faster mirror for users in China:
-#    tart pull ghcr.nju.edu.cn/cirruslabs/macos-tahoe-base:latest
-
-# 3. Give it the local name run.sh expects
-tart clone ghcr.io/cirruslabs/macos-tahoe-base:latest macos-tahoe-base
-```
-
-Verify with `tart list` — you should see `macos-tahoe-base`.
-
-## Running
-
-```bash
-make test-vm                                          # full suite (~30 min)
-make test-vm-run TEST=TestVM_Journey_FirstTimeUser    # one test
-```
-
-## Environment variables
-
-| Var | Default | Effect |
-|---|---|---|
-| `OPENBOOT_VM_BASE` | `macos-tahoe-base` | Local Tart image to clone from |
-| `OPENBOOT_VM_KEEP` | `0` | When `1`, do not destroy the VM at exit. Useful for debugging — attach with the SSH key path printed at exit. Remember to clean up manually. |
-
-## Troubleshooting
-
-- **`base image 'macos-tahoe-base' not found locally`** — run the one-time
-  setup above.
-- **SSH not reachable within 60s** — Tart logs dumped to stderr.
-  Try `OPENBOOT_VM_KEEP=1 make test-vm` (it'll still fail at boot, but the
-  VM is left running so you can `tart ssh openboot-ephemeral-<pid>` and
-  see what's up).
-- **Leaked VMs after a hard kill** — just run `make test-vm` again; run.sh
-  sweeps all `openboot-ephemeral-*` VMs on startup automatically. If you
-  want to inspect a leaked VM before deleting it, stop and delete it manually:
-
-  ```bash
-  tart stop openboot-ephemeral-<pid>
-  tart delete openboot-ephemeral-<pid>
-  ```
-
-- **Base image needs updating** — re-pull and re-clone:
-
-  ```bash
-  tart delete macos-tahoe-base
-  tart pull ghcr.io/cirruslabs/macos-tahoe-base:latest
-  tart clone ghcr.io/cirruslabs/macos-tahoe-base:latest macos-tahoe-base
-  ```
-
-## Why a base image (not vanilla)
-
-`-base` includes Xcode CLI tools and Homebrew pre-installed. `run.sh`
-installs Go on first boot via `mise` (which the base image ships). openboot
-*does* install Homebrew, so "fresh Mac" purists would prefer
-`macos-tahoe-vanilla`. We pick `-base` because:
-
-1. Boot-to-test latency drops significantly vs. having to bootstrap brew
-   and Go from scratch.
-2. `MacHost.Run("brew install ...")` exercises the "already-installed
-   brew" code path, which is the more common real-world scenario (users
-   running openboot a second time, or after `brew install` ran for some
-   other reason).
-3. Tests that specifically need to exercise the "no brew yet" path can
-   uninstall it as the first step.
