 Critical whittle.py notes:
 - `openroad` must be on PATH (whittle uses it internally to read ODB counts).
-  Use `ln -sf $(pwd)/bazel-bin/openroad ~/.local/bin/`
+  Use `PATH="$(pwd)/bazel-bin:$PATH"` — never install to `~/.local/bin/`.
 - Use absolute paths for `--base_db_path` and in `--step` (whittle changes cwd)
 - Don't pipe whittle output through `tail` — use `tee` with `pipefail`
 - Use `--use_stdout` when errors go to stdout (not just stderr)

-Put it on PATH (or use the full path in the verify step):
+**Never install openroad to ~/.local/bin/ or anywhere on the default PATH.**
