+# nix
+- For R.nvim in the Nix wrapper, both RNVIM_COMPLDIR (C server compilation) and a writable R_LIBS_USER directory (nvimcom R package installation) must be configured — fixing only one leaves permission errors in the other. Confidence: 0.65
+- For R.nvim writable directories (RNVIM_COMPLDIR, R_LIBS_USER, TMPDIR), prefer project-local paths (e.g., $PWD/.Rlibs) over global cache paths — the cache approach may let the build succeed but still fail at runtime. Confidence: 0.70
