`[2026-07-06]` **The Bash tool's `grep` is a ugrep-wrapper (`--ignore-files -I`) that silently returns NOTHING on some files** (e.g. `src/ratatoskr/web/static/index.html`) — greps for `<script`/`/api` came back empty on a file that clearly contains them. Use `python3` (regex over `open(f)`), `/usr/bin/rg`, or the Read tool for those files; never trust an empty `grep` result on the SPA.
