The five enhancements

Enhancement	What it does
Duration + thinking segments	Appends · took X · M thinking segments in a faded tertiary colour, computed by the plugin's own per-turn state machine
Fold-decision persistence	The official fold state is in-memory only (lost on refresh); the plugin records your choice in localStorage and restores it on reload
completed whitelist (optional, off by default)	The official bar folds every settled turn regardless of outcome; when enabled, aborted / errored / max-tokens turns stay expanded and render no bar at all
Auto-load earlier history	Scrolling near the top of a conversation automatically invokes the official loadOlder(), so long-session history arrives pre-folded
Standalone fold bar	When the official renderer finds no finalized answer (a turn stopped on a tool call — interrupted or errored), it renders no fold bar at all and leaves the whole turn flat. The plugin adds its own bar for such closed turns — expanded by default, collapsible, decision persisted like any other

Purely front-end: no backend changes, no session-store changes, zero server-side residue after uninstall. Pinned to DSH 0.1.5-rc.2 (official turn-process fold bar, keyed slot conversation.chat.node, useTurnData injection surface).

How it works

Takeover: ctx.slots.register({ key: 'turn-process', priority: -1 }) — the lowest priority renders among same-key registrations. Expanding runs a CSS height transition (no measurement, via interpolate-size); collapsing runs a Web Animations API height transition that folds the official geometry changes into the same batch — both reversible mid-flight and prefers-reduced-motion aware. When the official renderer finds no finalized answer it renders no bar at all; the plugin supplies its own standalone bar for those closed turns.

Install (4 steps)

1. Get UNscientific-9-dsh-turnfold-0.5.0.tgz (see Releases) and put it in a fixed directory.

2. Edit the DSH web profile's %USERPROFILE%\.dsh\profiles\web\package.json and add the dependency:

   {
     "dependencies": {
       "@UNscientific-9/dsh-turnfold": "file:D:/path/to/UNscientific-9-dsh-turnfold-0.5.0.tgz"
     }
   }
   

3. In the profile directory, run pnpm install, then restart DSH web and hard-refresh the browser (Ctrl+Shift+R).

4. The browser console should show [dsh.turnfold] v0.5.0 loaded, and completed turns get the official-style fold bar with a faded · took X · M thinking segments tail.

Requires DSH web 0.1.5-rc.2 (the fold bar shipped in the 0.1.2 line; this build is pinned to the 0.1.5 host API).

Configuration (localStorage)

Key	Default	Effect
dsh.turn-collapse.completedOnly	unset	Set to '1' to keep aborted / errored / max-tokens turns expanded; remove the key to restore the official behaviour
dsh.turn-collapse.autoLoad	'1'	Set to '0' to disable auto-load of earlier history

Uninstall / rollback

Remove the @UNscientific-9/dsh-turnfold line from the profile package.json, run pnpm install, restart DSH web and hard-refresh. Everything the plugin owns lives in the browser (three localStorage keys + one <style> tag); removing it restores the pure official fold bar.
