Right-side message navigation rail for DeepSeek Harness.
Per-message tick marks · hover preview drawer · smooth jump · star bookmarks · realtime slide animation
TL;DR: A persistent right-side rail that turns your conversation history into a navigable timeline — hover to preview, click to jump, star to bookmark. Built with official
--dsw-*tokens for seamless integration with the DSH ecosystem.
DSH Lifeline is a persistent DSH bundle plugin built on the Cordis composition model. It renders a vertical navigation rail on the right side of the conversation page, with per-message tick marks that track your scroll position in real time. Hovering expands a preview drawer; clicking jumps to any historical message with smooth scrolling. The rail dynamically avoids other right-side panels (widgets, sidebar, etc.) and slides in/out with a coordinated animation when panels open or close.
| Capability | Detail |
|---|---|
| Per-message ticks | Every user message generates one tick mark on the vertical rail |
| Scroll-spy highlight | The tick nearest to your current reading position lights up in brand blue |
| Center-axis alignment | The rail's center axis aligns with the message layout's content edge — no content occlusion |
| Always visible | Stays pinned on the right side; auto-hides when the session has < 2 user messages |
| Narrow-screen adaptive | Auto-hides at viewport ≤ 767px (mobile / narrow windows) |
| Capability | Detail |
|---|---|
| Hover to expand | Mousing over the rail expands a 260px-wide preview drawer with message text |
| Smooth slide | The drawer slides in from the right with a CSS transition (interruptible) |
| Click to jump | Clicking any item smoothly scrolls the chat to that message (loads older history on demand) |
| Star bookmarks | Click ★ to star a message; starred ticks glow gold in the collapsed rail; "★ Marked only" filter in the drawer |
| Virtualized list | Drawer uses a virtual list (30px row height); smooth even with thousands of turns |
| Official tokens | Background --dsw-alias-bg-layer-1, border --dsw-alias-border-l2, shadow --dsw-shadow-lv3 — matches DSH input box / widget panels in both themes |
| Capability | Detail |
|---|---|
| Frame-by-frame sync | When a right-side panel (widgets, sidebar) opens or closes, the rail follows the conversation-area width change every frame |
| 220ms ease-out tween | Smooth entry/exit with interruptible animation — rapid open→close→open animates seamlessly |
| Content-flow reference | Positioning uses the conversation content-flow container's live rect; no stale overlay caches |
| Capability | Detail |
|---|---|
| Full session index | Host REST endpoint (/api/chat-timeline-index) serves the complete user-message index with incremental pushes |
| No page-load needed | Long conversations show every historical tick without paging through "load earlier" |
| Rewind integration | Withdrawn / rewound messages are automatically removed from the timeline via dsh-rewind |
| Capability | Detail |
|---|---|
| Dynamic right-edge tracking | Detects right-side workbenches (dsh-better-sidebar, dsh-widgets, aionui) and shifts to align |
| Multi-panel aware | Handles two overlapping right panels simultaneously |
