Move update downloads into the background and prompt only after the update is ready, so the global update UI no longer pins a progress panel over the app. Keep the About page as the detailed status surface and make failed downloads or installs retryable without losing the prepared update.
Constraint: Tauri updater install still needs an explicit user restart action after download
Rejected: Keep showing global download progress | it preserves the blocking top-right experience that triggered the complaint
Confidence: high
Scope-risk: moderate
Directive: Do not show the global update prompt before status is downloaded without rechecking the desktop UX complaint

Not-tested: Real signed release artifact update from an installed older desktop build
Desktop destructive confirmations had split implementations: shared ConfirmDialog, hand-rolled modals, inline task popovers, and a diagnostics window.confirm path. This adds shared ActionDialog and ConfirmPopover primitives, keeps ConfirmDialog as the simple two-action wrapper, and migrates the known desktop confirmation flows onto those shared surfaces.
Constraint: Running-tab close needs three actions, so the two-button ConfirmDialog API was not enough.
Rejected: Force every confirmation through ConfirmDialog | would either lose the keep-running action or make ConfirmDialog too broad for inline popovers.
Confidence: high
Scope-risk: moderate
Directive: Add new desktop confirmation flows through ActionDialog, ConfirmDialog, or ConfirmPopover instead of hand-rolled overlays.
Tested: cd desktop && bun run test -- AdapterSettings.test.tsx mcpSettings.test.tsx TabBar.test.tsx PermissionModeSelector.test.tsx diagnosticsSettings.test.tsx
Tested: bun run check:desktop
Tested: git diff --check
Tested: Chrome DevTools smoke for provider delete and diagnostics clear-log confirmation dialogs
Not-tested: Agent Browser smoke because the local agent-browser CLI hung on open/snapshot/doctor/close commands.
Streaming assistant output can expose incomplete Mermaid fences before the
model has closed the diagram syntax. Keep those blocks in a generating state
until the assistant message finalizes, then render the completed diagram. Also
preserve Mermaid label content in sanitized SVG output so preview and expanded
views keep node text visible.
Constraint: marked treats unclosed fenced code as a code block during streaming
Rejected: Keep retrying Mermaid render on partial syntax | users still see parse errors while valid output is incomplete
Confidence: high
Scope-risk: narrow
Directive: Do not render parser-backed diagram components from streaming markdown without an explicit pending state
Tested: bun run check:desktop
Not-tested: live provider smoke after Codex host Crashpad renderer/utility dumps were observed
Message action controls stay visible through focus-within for keyboard navigation, but pointer clicks left the copy/fork buttons focused after the mouse moved away. Release pointer focus on message actions so hover controls return to their quiet state while keeping Tab focus behavior intact.
Constraint: Message actions use focus-within for keyboard accessibility and should not remove that path.
Rejected: Remove focus-within reveal | would regress keyboard users who tab to copy or fork.
Confidence: high
Scope-risk: narrow
Directive: Keep pointer-only blur scoped to message action controls; do not remove focus-within without a replacement keyboard affordance.

Dark-mode Markdown text was still inheriting Tailwind Typography's default prose color, so normal and italic text could render dark while strong text used the app theme token.
Map markdown prose variables to the desktop theme tokens, move code-viewer hover and line-number styling onto theme tokens, and make Mermaid/Diff rendering follow the active app theme. Write/Edit/tool result and workspace render paths were audited; their core code and diff surfaces already use theme tokens, with the DiffViewer theme handoff tightened here.
Constraint: Mermaid theme customization requires the base theme and concrete color values, so CSS theme tokens are resolved to hex before rendering.
Rejected: Add per-element prose utility overrides only | misses Tailwind Typography defaults for quotes, counters, tables, and future prose elements
Confidence: high
Scope-risk: moderate
Directive: Keep markdown, code, diff, and diagram colors routed through shared desktop theme tokens; do not reintroduce fixed light backgrounds in chat renderers.

Not-tested: Full Tauri live desktop session with real provider output; browser broad-audit screenshot capture timed out, but computed colors were captured for all three themes.
MCP settings could remount into a full-page spinner even when cached server data was available, and overlapping refreshes could let stale responses replace newer state. Historical chat sessions also had no explicit history-loading state, so slow transcript reads looked like a blank session.
This keeps cached MCP/session lists visible during refresh, ignores stale list responses, clears the selected MCP server when returning to the list, and gives historical sessions explicit loading/error states with de-duped history loads.
Constraint: Fix must stay local-state focused and avoid changing MCP config persistence.
Rejected: Add a broad transcript/session indexing layer | too large for the issue-level stall fix.
Confidence: high
Scope-risk: moderate
Directive: Do not remove the stale-response guards without re-testing rapid settings navigation and session switching.

Not-tested: Manual Windows desktop reproduction for issue #648.
Message rows should stay visually quiet until the user needs copy or fork controls. The action row now appears on message hover/focus, uses icon-sized controls, and shows the message timestamp beside the actions with locale-aware recent and historical formats.
Constraint: Desktop chat actions already own copy and fork affordances, so the change keeps that surface instead of adding a separate always-visible timestamp row.
Rejected: Keep text-labeled Copy buttons | the row remained too visually heavy for every message.
Confidence: high
Scope-risk: narrow
Directive: Keep copy, fork, and timestamp as one hover/focus metadata row unless the message layout is redesigned as a whole.
Tested: bun run check:desktop
Not-tested: Live Tauri native packaging
A turn can touch many files; an open-with affordance on every row is noise.
Restrict the per-file 打开方式 pill to rendered-previewable types via a new
isPreviewableChangedFile() predicate. Source rows keep their inline diff toggle.

Each file row now shows a material-symbol document-type icon, bold filename,
and a type subtitle (e.g. 文档·MD / 代码·TS) alongside a labeled 「打开方式 ⌄」
pill replacing the old open_in_new icon button; diff-expand is preserved.

Extend the injection effect in AssistantMessage to also append a ▾ trigger
after inline <code> elements whose text is a browser-localhost or remote URL,
so AI-written run URLs like \`http://localhost:9527/\` get the same open-with
menu that markdown <a> links already receive.

Each file row in CurrentTurnChangeCard now has a sibling "open with" button
(open_in_new icon) that shows an OpenWithMenu, reusing buildOpenWithItems and
openWithContextForWorkspaceFile. HTML/XHTML files also get the in-app browser
option. Tests and i18n keys (openWith.title) included.

Wire createPicker into the preview-agent IIFE: enter/exit picker via host messages, bind DOM mousemove/click (capture phase) to picker hover/select, and on click emit a selection event carrying ElementMetadata + annotated screenshot. Route the selection event in previewEvents.ts through buildSelectionComposerText into queueComposerPrefill with the screenshot attachment.

Wire L1 link routing into assistant message rendering. AssistantMessage now
accepts an optional sessionId and, when present, builds an onLinkClick that runs
handlePreviewLink against the running local server base (getServerBaseUrl) and
the browser/workspace panel stores, preventing default on handled links.
MessageList passes sessionId through in the assistant_text case.
Adds getServerBaseUrl() to desktopRuntime as a synchronous wrapper over the api
client's cached getBaseUrl().
