dsh-rightbar (alpha.1)

The pack's own right bar — the right-hand column of the DeepSeek Harness web GUI: the tab strip with its "+" add control, the docking panel with split / float / fullscreen, the header expand button, the Start (guide) page, the tab-type registry other plugins register into, and the keyed tab body/title seats. Alpha.

What "the pack owns it" means

The right bar is a fork: lib/client.js is a byte-for-byte copy of the shipped @deepseek-ai/dsh-client-ui-sidebar-right bundle (same harness line as .dsh-version.json's dsh pin), with a generated banner and the module-table id rewritten to dsh-rightbar. The bundle layer then hard-disables the two core rows and inserts the pack's:

- id: ui-sidebar-right
  disabled: true
- id: ui-sidebar-files
  disabled: true
- insert:
    - id: rightbar
      name: 'dsh-rightbar'

So exactly one bar is mounted, and it is this package — the code can be changed here without touching any DeepSeek core file. The shipped @deepseek-ai/dsh-client-ui-sidebar-documentpreview row is deliberately left alone: it only consumes the sidebarRightTabs service and the sidebar.right.pane.tab seat, which this copy provides under the same names.

The contract other plugins use

Unchanged from the shipped bar (that is the point of a byte-for-byte fork):

• Registry (cordis service sidebarRightTabs): register({ id, kind, patterns?, priority?, canOpen?, title(address), guide? }) — id is also the slot key of the plugin's body/title.
• Controller (cordis service sidebarRight): openResource(address, opts), openTab(kind, opts), close, focus, split, float, dock, isExpanded, toggleExpanded.
• Seats: sidebar.right.pane.tab and sidebar.right.pane.tab.title (keyed by the definition id), sidebar.right.tab.guide (chain), sidebar.right.tab.menu.item (list), plus the rightbar / rightbar.session panel seats and the conversation.session.header.corner expand button.
• The "+" control opens the Start page, which lists each registered type's guide entries; picking one calls openTab(kind, { replaceTab: true }).

dsh-rightbar-files (the Files tab) and dsh-editor (the editor tab) are the pack's own tab types on top of this bar.

Re-syncing the fork

When the pinned harness line moves:

pwsh -NoProfile -File scripts/sync-vendored.ps1
pwsh -NoProfile -File scripts/sync-vendored.ps1 -Check

(On Windows, powershell -NoProfile -ExecutionPolicy Bypass -File scripts\sync-vendored.ps1 works just as well: the script is OS-neutral.)

The script finds the harness node_modules (profile first, then the npm caches

• the Windows npm cache, ~/.npm/_npx, and the POSIX global module directories), copies each forked bundle, rewrites the module id, applies that fork's patch list, stamps the banner and prints hashes. -Check reports drift without writing (exit 1 when out of sync). If the bar's slot/service surface changed in the new line, review the diff before installing — a fork does not silently track upstream.

Layout

cordis.patch.yml   bundle layer: disables the core bar + Files rows, inserts 'rightbar'
lib/index.js       Node half: no-op row so the browser bundle ships
lib/client.js      GENERATED vendored bar (do not edit; re-sync instead)
