 ### Changed
 
+- **tests**: Jest's haste map no longer indexes `.claude/` (via `modulePathIgnorePatterns`). A leftover agent worktree under `.claude/worktrees/` duplicated the manual mocks in `tests/__mocks__/` and made every jest run emit a `jest-haste-map: duplicate manual mock found` warning; test files in worktrees were already excluded, but module indexing was not. Verified warning-free with a worktree present.
 - **BREAKING — package**: The package is now published as the scoped **`@deepl/cli`** (previously the unpublished working name `deepl-cli`). Scoped packages default to restricted visibility, so `publishConfig.access: "public"` is set explicitly — without it the publish fails. The `bin` name is unchanged: the command is still `deepl`, and scoping changes only the install string (`npm install -g @deepl/cli`). Repository, bugs, and homepage metadata now point at `github.com/DeepL/deepl-cli` directly instead of relying on the redirect from the legacy `DeepLcom` org name.
 - **BREAKING — cache/runtime**: The translation cache now uses Node's built-in `node:sqlite` module instead of the `better-sqlite3` native addon, and the CLI consequently requires **Node.js >= 24** (`engines.node` is now `>=24.0.0`). Node 24 is the first release where `node:sqlite` is non-experimental; Node 18/20 lack the module entirely and Node 22 would both warn on every invocation and downgrade the bundled SQLite (3.50.4 vs 3.53.1). Existing cache databases are read in place with no migration — the on-disk format is unchanged (SQLite 3.53.2-written files verified readable, WAL mode and `user_version` stamp included). **Migration**: upgrade to Node 24 (current LTS), e.g. `nvm install 24`; no other action is needed, and the cache keeps its contents.
