The DSH shell keeps its navigation (selected session, central panel, settings dialog/section) in memory only, so the browser Back/Forward buttons and page reloads lose your place. This client plugin mirrors that state into the URL hash and the browser history.

Features

URL hash reflects where you are:

#/session/<id>[/parent/<id>/mode/<m>][/panel/<id>][/settings/<section>]

Every user navigation does history.pushState, so Back/Forward work; changes during app startup use replaceState.
popstate / hashchange / loading a page with a hash restores the state (shareable, bookmarkable links to sessions, panels and settings sections).
Mouse buttons 4/5 (Back/Forward) map to history.back() / history.forward().

How it works

File	Role
`client.js`	Web client module (`@local/dsh-history-nav`), injects `@deepseek-ai/dsh-client-ui-layout` and `@deepseek-ai/dsh-client-ui-workspace`; owns all behaviour.
`index.js`	Empty Host half (`apply() {}`).
`cordis.patch.yml`	Bundle patch inserting the `dsh-history-nav` row.

Installation

Requirements: a working DeepSeek Harness (dsh) install with the web profile (or any profile that includes the Web UI).

Option A — install from git (recommended)

dsh plugin --profile web add git+https://git.rizzy.dev/DSH-Plugins/dsh-history-nav.git

You can also paste git+https://git.rizzy.dev/DSH-Plugins/dsh-history-nav.git into Settings → Plugins → Install in the Web UI, or ask the agent to install it with its plugin_manager tool (install_bundle).

The plugin manager adds @local/dsh-history-nav to dependencies and to dsh.profile.bundles in ~/.dsh/profiles/web/package.json.

Option B — local checkout (for development)

git clone https://git.rizzy.dev/DSH-Plugins/dsh-history-nav.git ~/dsh-plugins/dsh-history-nav
dsh plugin --profile web add link:$HOME/dsh-plugins/dsh-history-nav

With a link: install, edits in the checkout are picked up directly (client changes reload on page refresh, Host changes after a DSH restart or HMR reload).

Enable / verify

Make sure @local/dsh-history-nav is listed in dsh.profile.bundles of ~/.dsh/profiles/web/package.json (the installer does this; add it by hand if you edited package.json manually).
Restart DSH (dsh web) or reload the page.
Check Settings → Plugins: the @local/dsh-history-nav bundle should be enabled.

Uninstall

dsh plugin --profile web remove @local/dsh-history-nav

Updating

Re-run the add command from Option A (or git pull in your Option B checkout).

Configuration

None. Once enabled, open a session and watch the address bar update; use Back/Forward or reload the page to verify restoration.
