dsh-chat-fold

In long DeepSeek Harness sessions, the moment total messages outgrow the initial transcript window, the stock turn-folding shuts off for good. Every completed tool call, system prompt, and intermediate reasoning stays expanded forever, and the page just keeps growing. dsh-chat-fold restores that compact interaction: each settled turn collapses behind a single disclosure row above the final answer, keeping only your input, the final prose, and any errors visible. The disclosure reuses the stock, already-localized duration label and a rotating SVG chevron, so you can expand or re-collapse a turn in place without re-rendering it. Beyond folding, the plugin automatically preloads four extra stock pages when you pick a session, widening the default history window from 50 to as many as 250 messages. Everything is built on namespaced data attributes and one small stylesheet layered over stock semantic anchors; it never touches the Harness runtime, the relay, or React reconciliation. Turns still streaming are never folded, and the plugin stands down completely whenever stock folding is available, so it coexists cleanly with other client plugins.
