-## Behavior notes
-
-- NuGet installs handle pointer packages (meta-packages
-  that redirect to RID-specific binaries) automatically
-- NativeAOT single-file binaries are placed directly in
-  the install dir; managed tools use a `_<name>/`
-  subdirectory with a symlink or `.cmd` shim
-- `run` downloads to a cache, executes, and does not
-  install permanently
-- Package signatures are verified when present
+## Reliable behavior
+
+- Git updates verify that remote history is a
+  continuation of local history. If a force push
+  is detected, the update is refused — the user must
+  uninstall and reinstall the tool.
+- Pinned installs (`--tag`, `--rev`, `@ref`) are
+  immutable. `update` skips them and reports the
+  pinned ref. Changing versions requires an explicit
+  uninstall and reinstall.
+- Building from source requires the .NET SDK;
+  `--package` works without the SDK.
+- NuGet installs auto-enable roll-forward if the
+  tool targets an older runtime.
+- `--require-sourcelink` enforces SourceLink metadata
+  in installed assemblies.
 - Missing prereqs (git, .NET SDK) produce actionable
-  error messages with install links
