+### Fixed
+- `nvim/init.lua`: Mason no longer attempts to install `pyright` and
+  `bash-language-server` on hosts without npm/Node.js. Both servers use npm as
+  their install backend; the unconditional `ensure_installed` caused two noisy
+  failure messages on every Neovim launch on GPU servers. They are now guarded
+  behind `vim.fn.executable('npm') == 1`. Resolves #23.
+
+### Changed
+- `CLAUDE.md`, `AGENTS.md`: documented the Mason npm-conditional LSP server
+  guard so agents and humans know not to remove it or add new npm-dependent
+  servers outside of it.

+**Mason LSP servers** — `pyright` and `bash-language-server` are installed by

+needed). Do not remove this guard or add other npm-dependent servers without
+wrapping them in the same check.
