+# REMOVED — none of these resolve in the mise registry, so they installed
+# nothing and only produced warnings. Grouped by why they were wrong:
+#
+#   Already provided by a tool that IS listed above:
+#     cargo   -> ships with `rust`
+#     gofmt   -> ships with `go`
+#     pip     -> ships with `python`
+#
+#   Project-level dependencies, not system tools. These belong in
+#   package.json / pyproject.toml / mix.exs, not in a toolchain manager:
+#     vitest, jest, pytest, isort
+#
+#   Task runner that never installed:
+#     go-task -> not a registry name. NB the bare name `task` does not work
+#     either: `mise registry` LISTS it as `aqua:go-task/task`, but resolving
+#     `task@latest` still fails. Appearing in `mise registry` output is not
+#     sufficient to conclude a name resolves — check with `mise ls-remote`.
+#     Dropped entirely; this repo drives everything through the Justfile, so
+#     `just` is listed above instead.
+#
+#   Base system binaries that mise should not be shadowing on Linux:
+#     git, gnu-sed, gnu-grep, gnu-tar
+#
+# If a GNU-vs-BSD coreutils difference ever actually bites on macOS, add
+# `coreutils` (which does exist in the registry) rather than these names.

+# mise's `[alias]` maps an alias to a TOOL PLUGIN — it does not define tasks,
+# so none of these ever ran. mise also warns that `[alias]` is deprecated in
+# favour of `[tool_alias]`.
+#
+# They are not re-added as `[tasks]`, because the Justfile already defines
+# `build`, `test`, `fmt`, `fmt-check`, `lint`, `doctor` and `heal` properly and
+# for the languages this repo actually uses. Two competing task runners with
+# the same verb names — one of which silently falls through `||` chains to a
+# different language's build — is worse than one. Use `just <recipe>`.
