## Fixes - [#3] Status events now add/update a status ActivityNode in timeline (upsertWsStatusNode) - [#4] Done callback adds done node; error callback adds error node + sets session.status="error" - [#5] handleRegenerate fully synced with workspace: status/tool/card/done/error all handled - [#1][#2] localStorage persistence: completed/error sessions auto-saved, lazy-loaded on demand - [#1] handleSelectConversation preloads workspace sessions from localStorage for history messages - Refactored completeWsSession to include done ActivityNode in timeline - Added errorWsSession, upsertWsStatusNode, saveWsToStorage, loadWsFromStorage helpers ## Known limitation - [#7] workspace_card merge:true not yet used by backend (all cards are append-only for now) - History workspace recovery depends on localStorage (browser-local, not cross-device) Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
