 A CLI installer tool for dAppBooster projects. It supports two **stacks** and two **modes**:
 
 - **Stacks:** `evm` (the original dAppBooster for EVM chains) and `canton` (dAppBooster for Canton: Daml ledger, Carpincho wallet, off-chain services). Each stack declares its own source repository, ref strategy (tag-latest vs branch), package manager, env files, optional `removeAfterClone` paths, and features.
-- **Interactive** (default): React + Ink TUI that prompts for stack first, then project name, then clone → installation mode → optional packages → install → cleanup → post-install. The stack prompt is skipped when `--canton`, `--evm`, or `--stack` is supplied.
-- **Non-interactive**: Flag-driven (`--ni` or auto-detected when not a TTY) for AI agents and CI. Outputs JSON to stdout. Run `--info` for stack + feature discovery, then `--canton`/`--evm` (or `--stack`) + `--name` + `--mode` [+ `--features`]. Omitting a stack flag in non-interactive mode defaults to `evm` for backward compatibility.

+Installation modes are stack-aware via `getInstallationModes(stack)` — Canton offers `default` / `full` / `custom`, EVM offers `full` / `custom`. The `default: boolean` flag on a feature has two roles: it pre-checks the feature in the custom multiselect **and** defines membership in `default` mode (`getDefaultFeatureNames(stack)` = the `default: true` set). `default` mode is Canton-only because EVM has no `default: false` features (there it would equal `full`).
+
 `getStackConfig(stack)` reads the base config and overlays the env-var overrides `DAPPBOOSTER_<STACK>_REPO_URL` and `DAPPBOOSTER_<STACK>_REF` before returning — that's the single hook for retargeting either stack at a fork or pre-release branch without editing code.
 
 `getFeatureNames(stack)` and `isFeatureNameValid(stack, name)` are the per-stack feature accessors. There is no global `featureDefinitions` export — that would imply a single stack.

 When adding a new feature, add it to the relevant stack's `features` map. Programmatic consumers pick it up automatically. Canton feature cleanup is fully data-driven from `paths` (see the Operations Layer below), so a new Canton feature needs no cleanup code — only its `paths`. EVM features still need an explicit per-feature cleanup function. The CLI `--help` text in `cli.tsx` maintains its own copy in both cases.

After that, runs `fs.rm` for every entry in `stack.removeAfterClone` (empty for both stacks today), removes `.git`, and reinitializes with `git init`. Uses `execFile` everywhere except the tag-latest shell substitution. |
 | `createEnvFile(stack, projectFolder, features?)` | Copies every entry from `stack.envFiles`. Entries with `ifFeature` are skipped unless the named feature is in the selection (e.g. Canton's `carpincho-wallet/.env.local` only when `carpincho` is selected). |

-| `cleanupFiles(stack, projectFolder, mode, features, onProgress?)` | First runs **repository hygiene** (every stack/mode): both stacks always remove `.github` (CI) and the husky/commitlint automation (`.husky`, `.lintstagedrc.mjs`, `commitlint.config.js`) and sanitize tooling deps/scripts from `package.json`; **EVM additionally** always removes its own agent metadata (`.claude`, `AGENTS.md`, `CLAUDE.md`, `architecture.md`), whereas **Canton keeps that metadata** under the optional `llm` feature. Then dispatches to `cleanupEvmFiles` or `cleanupCantonFiles`. EVM removes deselected feature files via per-feature functions plus the `.install-files` staging directory, and patches `package.json` by feature name. Canton cleanup is **data-driven**: it loops the stack's features and, in custom mode, removes each deselected feature's `paths` (e.g. `counter/`, `e2e/`, `carpincho-wallet`, the `llm` artifact paths). The removed directories then drive `package.json` script stripping by **command target** — any script whose command invokes a removed directory is dropped (so deselecting `carpincho` strips `wallet:dev` / `carpincho:build:extension`). Command-based matching keeps cleanup correct as the upstream repo renames or adds scripts. In `full` mode no feature paths are removed, so a full Canton scaffold keeps `carpincho-wallet`, the agent docs, and every script. Canton then makes an initial `git` commit of the scaffold. |

Full: `<pm> install`. `default`/`custom` with packages to remove: `<pm> remove` (pnpm) or `<pm> uninstall` (npm) + `<pm> run postinstall`; with nothing to remove: `<pm> install`. Canton features all carry `packages: []`, so Canton always runs a plain `npm install` (husky-dep removal happens in cleanup, not here — the Canton template has no `postinstall` script). `execFile` only — never shell. |
+| `cleanupFiles(stack, projectFolder, mode, features, onProgress?)` | **EVM** runs **repository hygiene** first (always): removes `.github` (CI), the husky/commitlint automation (`.husky`, `.lintstagedrc.mjs`, `commitlint.config.js`), and its own agent metadata (`.claude`, `AGENTS.md`, `CLAUDE.md`, `architecture.md`), and sanitizes tooling deps/scripts from `package.json`; then `cleanupEvmFiles` removes deselected feature files via per-feature functions plus the `.install-files` staging directory. **Canton** runs **no forced hygiene** — `.github` and the pre-commit automation are the optional `github` and `precommit` features. `cleanupCantonFiles` is **data-driven**: for `default` and `custom` modes (not `full`) it loops the stack's features and removes each deselected feature's `paths` (`github` → `.github`; `precommit` → the husky files; `carpincho` → `carpincho-wallet`; `llm` → the agent/LLM artifacts). Removed directories drive `package.json` script stripping by **command target** — any script whose command invokes a removed directory is dropped (so deselecting `carpincho` strips `wallet:dev` / `carpincho:build:extension`). When `precommit` is removed it additionally strips the `prepare`/commitlint scripts and the husky/lint-staged/commitlint dev-dependencies. In `full` mode nothing is removed, so a full Canton scaffold keeps `.github`, the hooks, `carpincho-wallet`, and the agent docs. Canton then makes an initial `git` commit of the scaffold. |

+1. **`source/constants/config.ts`** — add an entry to the stack's `features` map. The `default` flag governs both the custom-mode pre-check and `default`-mode membership: set `default: true` for "kept by the recommended install", `default: false` for "removed by default / opt-in" (Canton's `github` and `precommit`). For **Canton**, also list the feature's `paths`: cleanup is data-driven, so no cleanup code is needed and scripts that target a removed directory are stripped automatically.

 2. **`source/operations/cleanupFiles.ts`** — **EVM only**: add a cleanup function for the feature and call it from `cleanupEvmFiles` when deselected; if it has scripts, add removal to `patchPackageJsonEvm`. Canton needs no change here.
 3. **`source/components/steps/PostInstall.tsx`** — extend stack-specific instructions if needed.
 4. **`source/cli.tsx`** — update the `--help` text.
