+# PLAN — release 0.5.1

+- increment: Cut `@pharn-dev/pharn@0.5.1` — bump `package.json` / `package-lock.json` version,
+  fold the post-0.5.0 `@clack/prompts` runtime bump into `CHANGELOG.md`, refresh compare links,
+  then open the PR and cut the `v0.5.1` GitHub Release (which triggers `publish.yml`).
+- layer(s): repo-meta — version + release notes only. No `src/**` / `tests/**` changes in this
+  increment (the clack type narrowing already landed on `main` via #193).

+- **`@clack/prompts` bumped from `^1.7.0` to `^1.8.1`.** This is a runtime dependency of every
+  interactive prompt (`init`, `add`, `remove`, `update`). The accompanying type narrowing in
+  `runArchetypeSummary` keeps the install/cancel return typed under clack 1.8's `Value | symbol`
+  select signature; prompt behavior is unchanged.
