+### Changed
+
+- **Bundled `pi-toolkit` settings template: `pi-fork` balanced tier bumped to
+  `eu.anthropic.claude-sonnet-5`** (was `claude-sonnet-4-6`), matching the model
+  now in use. The image clones `pi-toolkit@main` into `/opt/pi-toolkit` at build
+  time, so the next build bundles it automatically (pi-toolkit `0010417`); the
+  same commit also refreshes the template's `enabledModels` and the README
+  examples. Seed-only: existing containers keep their live `~/.pi/agent/settings.json`
+  (the entrypoint merge is live-wins), so only fresh `~/.pi` volumes are affected.
