<!--
Before filing: run `pnpm typecheck && pnpm test && pnpm build` on the failing
checkout and paste the real output below. Reports without a reproduction are
much harder to act on.
-->

## Environment

| | |
|---|---|
| dsh-notebook version | <!-- e.g. 0.1.0, or the git commit you linked in --> |
| DSH version | <!-- `dsh --version`, e.g. 0.1.1-rc.2 --> |
| dsh-better-sidebar version | <!-- e.g. 0.12.1, or "not installed" --> |
| OS / Node | <!-- e.g. macOS 15, Node v22.23.2 --> |
| Install path | <!-- `dsh plugin --profile web add …` / manual `link:` / other --> |

## Which sidebar tier was active?

The plugin picks one of three tiers at runtime:

- [ ] **tier 1 `native`** — DSH exposes `ctx.sidebarRightTabs`
- [ ] **tier 2 `service`** — `ctx.betterSidebar` exists (better-sidebar 0.4.0–0.18.x)
- [ ] **tier 3 `standalone`** — no sidebar product installed, so the plugin draws its own panel
- [ ] not sure
