Summary

homeSpec.programs.vscodium.languages.python now follows the org Python standard (uv2nix skill, pkgs template .vscode/) instead of basedpyright.

 extensions (languages.python)
   ms-python.python
   ms-python.debugpy
-  detachhead.basedpyright
+  astral-sh.ty                 # language server, as checks.python-ty is the type check
   charliermarsh.ruff
+  tamasfe.even-better-toml     # pyproject.toml incl. [tool.uv|ruff|ty]

 userSettings
+  "ty.path"   = [ <org nixpkgs ty>/bin/ty ]      # same version as CI
+  "ruff.path" = [ <org nixpkgs ruff>/bin/ruff ]  # same version as treefmt
+  "ty.diagnosticMode" = "workspace"
+  "python.terminal.activateEnvironment" = false
+  "python.testing.pytestEnabled" = true; unittestEnabled = false
   "[python]".codeActionsOnSave
+    "source.fixAll" = "explicit"
     "source.organizeImports" = "explicit"
 nixd nixpkgs.expr (languages.nix.flake)
-  import f.inputs.nixpkgs { }
+  import f.inputs.nixpkgs { overlays = [ (f.inputs.org-pkgs.overlays.default or (_: _: { })) ]; }

These are user-wide fallbacks. An org repo's .vscode/settings.json still wins and points ty, ruff and the interpreter at .devenv/profile.

Evidence

• Before: netsa's extensions had detachhead.basedpyright with no ty; ruff ran the extension's bundled binary; nixd's user-level nixpkgs had no org packages.
  After (home's kamrui-h1 evaluated with --override-input modules path:…):
  • extensions: ms-python-python-2026.4.0, ms-python-debugpy-2026.6.0, astral-sh-ty-2026.90.0, charliermarsh-ruff-2026.94.0, tamasfe-even-better-toml-0.21.2
  • ruff.path → ruff-0.17.2, ty.path → ty-0.0.91 (the org nixpkgs, same as CI)
  • home-manager.users.netsa.home-files builds
  • nixd expr: home gives pkgs.moscripts; a flake without org-pkgs (pkgs) falls back to plain nixpkgs
• fmt: clean. check: all checks passed (one existing stdenv.isDarwin deprecation warning, not a deny).

Merge Danger

Door: two-way

Blast Radius: editor

Only VSCodium users with languages.python.enable are affected (netsa; matt if enabled) once home bumps modules. With mutableExtensions = true, an Open VSX copy of basedpyright installed by hand stays until the user uninstalls it.

Merge order: this PR, then the skills docs PR, then home (nix flake update modules).
