-- Memory limit: 4G
-- Mounts: `~/dev` **read-only** at `/host`, `~/.sandlot` read-write at `/sandlot`
-- Host symlinks: creates `~/dev` → `/host` and `~/.sandlot` → `/sandlot` inside the container so host-absolute worktree paths resolve correctly
-- `containerPath()` in `vm.ts` translates host paths to container paths (`~/.sandlot/…` → `/sandlot/…`, `~/dev/…` → `/host/…`)
-- Provisioned once on first use: apt installs `curl git fish unzip`, then installs Bun, Claude Code, neofetch, and Neovim
-- Binary caching: after first install, binaries are cached in `~/.sandlot/.cache/` (bun, claude, neofetch, nvim.tar.gz) — subsequent `vm create` uses cached copies, skipping downloads

 ## Shell Command Pattern
 
@@ -137,20 +131,12 @@ Always use `.nothrow()` for commands that may fail non-fatally. Use `.quiet()` t
 
 - `vm.exec()` prepends `export PATH=$HOME/.local/bin:$PATH` so `claude` binary is found
 - `vm.claude()` uses `Bun.spawn` with `stdin/stdout/stderr: "inherit"` for interactive TTY; in print mode (`-p`), captures stdout via pipe and returns the output
-- `vm.claude()` runs Claude with `--dangerously-skip-permissions`, `--model claude-opus-4-6`, and `--append-system-prompt` (system prompt describes the container environment)
-- `vm.claude()` retry logic: if exit code is non-zero and `--continue` was used, retries without `--continue`
 - `vm.claudePipe()` writes input to a temp file in `~/.sandlot/`, pipes it to `claude -p` inside the container, and returns the result — used for commit message generation and conflict resolution
 - `vm.isClaudeActive()` reads activity marker files written by the in-container `sandlot-activity` hook script
 - Branch creation in `createWorktree()` handles three cases: local branch, remote branch (tracks origin), new branch from HEAD
 - `sandlot new` accepts a prompt instead of a branch name — derives a 2-word branch name via the Anthropic API (Haiku), falling back to simple text munging
-- `sandlot open` always passes `continue: true` to `vm.claude()` to resume the previous conversation
 - `sandlot save` uses `vm.claudePipe()` to generate commit messages from the staged diff
-- `sandlot merge`, `sandlot squash`, and `sandlot rebase` use `vm.claudePipe()` to resolve merge conflicts automatically
-- `sandlot squash` generates an AI commit message for the squash commit via `claudePipe()`; falls back to `"squash <branch>"`
-- `sandlot merge` and `sandlot squash` both delegate to `mergeAndClose()` in `helpers.ts`, which merges, resolves conflicts, commits, and then calls `closeAction()` to clean up
-- `sandlot list` discovers missing session prompts by parsing Claude's `history.jsonl` from inside the container
-- `sandlot list` shows four status icons: idle (dim `◌`), active (cyan `◯`), dirty/unsaved (yellow `◎`), saved (green `●`)
+- `sandlot merge` and `sandlot rebase` use `vm.claudePipe()` to resolve merge conflicts automatically
 - `sandlot new` and `sandlot open` auto-save changes when Claude exits (disable with `--no-save`)
-- `sandlot close` has a hidden `rm` alias
-- Default behavior (no subcommand): always runs `list` (which prints "No active sessions." if empty)
+- Default behavior (no subcommand): shows `list` if sessions exist, otherwise shows help
 - `.sandlot/` should be in the repo's `.gitignore`
