dsh-rightbar

dsh-rightbar (alpha.6)

The pack's own right bar — the web GUI's right-hand column: the tab strip with its "+" control, the docking panel (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.

lib/client.js is a GENERATED fork of the shipped @deepseek-ai/dsh-client-ui-sidebar-right bundle (the line pinned in .dsh-version.json), carrying the patch list in scripts/tools/sync-vendored.ps1. cordis.patch.yml hard-disables the two core rows and inserts this package's, so exactly one bar is mounted and it is this one:

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

The shipped @deepseek-ai/dsh-client-ui-sidebar-documentpreview row is left alone on purpose: it only consumes the sidebarRightTabs service and the sidebar.right.pane.tab seat, which this copy provides under the same names.

What it adds

• Four docked panes, not two. The fork's eleven patches lift the shipped two-pane cap in all five places it is enforced, re-open the top/bottom drop bands, and let the kit's own canSplit be the ceiling.
• A renderer that can draw the tree those bands build. The kit's DockLayout renders one pane or two side by side and THROWS on anything else, so a stacked pane reached the shell's slot boundary as a crash. The fork renders the kit's recursive DockSurface instead, through its one hand-written component vendor/dock-tree.js (spliced in verbatim by the sync script), with DockLayout only as the fallback for a kit line without DockSurface.
• The three things the flat renderer's tab host provided, all on the data-dockkit-host="dock" wrapper DockTree emits: the bar's LEFT SEAM (border-right: .5px solid var(--dsw-alias-border-l3), the token the app's own column separators use), an OPAQUE --dsw-alias-bg-base fill on the box the tab bodies are MOUNTED IN (without it a fullscreen bar shows the conversation through every pixel the active tab does not paint itself), and the fullscreen layer.

The wrapper must also keep pointer-events: auto (the bar's own stylesheet turns the PANEL's pointer events off, so without it the whole bar is deaf to the mouse), the kit's FloatLayer (a floated tab is otherwise unreachable) and the active / expanded / keepMounted gates.

The fullscreen layer goes on the PANEL, not the wrapper:

.P3OORG_panel[data-sidebar-right-panel=fullscreen]{ --dsh-dockkit-dock-layer:40; z-index:40 }

40 is the app's own ladder: above every persistent layer (composer seat 7/9, frame handles and seats 11/15/20, this pack's command dock 21, the sidebar's fixed controls 30) and below every transient one (the kit's tab menu 70, tooltips and menus 100/101, the modal root 1000, toasts and portals 1100). Push mode is untouched.

How it plugs in

• sidebarRightTabs (registry): register({ id, kind, patterns?, priority?, canOpen?, title(address), guide? }); id is also the slot key of the type's body and title.
• sidebarRight (controller): 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 definition id), sidebar.right.tab.guide (chain, with sidebar.right.tab.guide.entry), sidebar.right.tab.menu.item (list), 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 }).

The pack's own tab types resolve these services — dsh-rightbar-files (Files), dsh-editor, dsh-gittree, dsh-image, dsh-audio, dsh-video, dsh-pdf, dsh-diagrams — as does the shipped document preview.

Limits

• Four docked panes; floats do not count against the ceiling, so they remain the way to see more at once.
• lib/client.js is generated — never hand-edit it. Re-sync instead; the sync script verifies the component inside it is byte-for-byte vendor/dock-tree.js.
• A re-sync accepts only the PINNED harness line (an older line's sidebar-right is a different bundle entirely); -CoreModules is the one deliberate override.
• A fullscreen bar covers the pack's own command dock (21). If the dock should survive one, that number belongs to dsh-cmdbar.

Verify

node scripts/checks/check-client-bundles.mjs
pwsh -NoProfile -File scripts/tools/sync-vendored.ps1 -Check

The client check pins the cap lift, the renderer, the seam, the fill and the fullscreen layer as recorded patches, and fails when a harness bump moves the app's z-index ladder under the bar.

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)
vendor/dock-tree.js   the dock renderer the sync script splices into it
