# v2.1.1

This is an urgent browser-startup hotfix for DVR 2.1.0.

## Fixed

- Fixes #367: DSH Web could fail while applying `dsh-vision-router` with `cannot get property "remote.session" without inject`.
- The 2.1.0 client Host compatibility prelude no longer probes the optional `remote.session` namespace through the traceable `ctx.remote` proxy. It resolves the optional namespace through `ctx.get('remote.session')` first and keeps a guarded fallback for older/non-Cordis harnesses.
- The new Host model-catalog bridge still uses `remote.session.modelCatalog()` when available, while older supported Hosts keep the original `connection.api.llm.models()` path and exact legacy Remote/Connection surfaces.

## Regression coverage

- Adds a production-shaped regression where reading `ctx.remote.session` throws the exact #367 Cordis error while `ctx.get('remote.session')` succeeds.
- Adds the same test to the default Node 22/24 suite and the Web compatibility suite.
- Keeps a fail-closed legacy-host regression so the hotfix does not turn the optional alpha namespace into a hard browser dependency.

## Upgrade

Users on 2.1.0 who hit the browser loader failure should upgrade to 2.1.1 and restart the DSH Web/Desktop process. No settings migration is required.
