+## Computer Use for the macOS app
+
+- Build the real app bundle with `cargo bundle-macos`.
+- Use Computer Use against the exact app path `target/release/Blogging Desktop Server.app` (resolved to its absolute path), then raise that window before interacting with it.
+- Do not use `cargo run` for Computer Use: it starts RuDS as a child of the command runner and Computer Use cannot attach to it as a macOS app.
+- Do not run `open` on `target/debug/bds-ui`; macOS hands the executable to Ghostty instead of launching RuDS as an app.
+- Do not target only the `de.rfc1437.ruds` bundle identifier because both the installed app and the repository build may share it; always use the exact repository bundle path.
+- Do not improvise with AppleScript, Dock automation, or raw screen-capture workarounds. Use the Computer Use skill and its `node_repl` runtime.

 ## Plan Mode
 
 - Make the plan extremely concise. Sacrifice grammar for the sake of concision.

+- Native Iced desktop workspace with localized menus, tabs, anchored editor popovers, automatically paged post/media sidebars, dialogs, tasks, embedded Wry previews, and a live Pico CSS theme editor.
 - Post and translation authoring with draft/published lifecycle, metadata, tags, categories, links, media, and batch gallery-image import.
 - Media import, thumbnails, metadata translations, filters, validation, post assignment, and sequential drag-and-drop insertion into post editors.
 - WordPress WXR migration with saved analyses, HTML-to-Markdown and shortcode conversion, conflict/taxonomy review, recoverable 500-item execution batches, media-parent linking, progress reporting, and optional AI-assisted taxonomy mapping.
 - Post, Liquid template, and Lua script editing with dedicated syntax highlighting and explicit syntax-check feedback, using a custom Ropey/Syntect/Cosmic Text editor and the documented, bDS2-signature-compatible project-scoped [`bds` host API](docs/scripting/API_REFERENCE.md) across utilities, rendered macros, and Blogmark transforms, including airplane-gated Git sync.
-- SQLite and filesystem persistence with frontmatter, sidecars, rebuild, metadata diff/repair, and FTS5 search.
+- SQLite and filesystem persistence with frontmatter, sidecars, rebuild, metadata diff/repair, bDS2-compatible NFD slug generation, and FTS5 search.

+- Optional on-device multilingual semantic search and similar-post tag suggestions backed by a persistent USearch index, plus always-available partial-name tag autocomplete and duplicate-post review in the desktop workspace.
 - Read-only in-app browsers in the Help menu for the bundled global `DOCUMENTATION.md`, the generated Lua API reference with public types and runnable examples, the [CLI/server/TUI documentation](CLI.md), and the [MCP server documentation](MCP.md), with safe GFM rendering and confirmed external links.
 - A localized OPML menu editor manages pages, submenus, and category archives with protected Home ordering, keyboard-accessible tree controls, drag-and-drop, and bDS2-compatible persistence.
 - Project-scoped typed domain events synchronize desktop views with shared-engine and future CLI mutations; persisted CLI notifications are consumed once, and the selected UI language is shared through settings.

 - Persistent conversational AI with safe Markdown, streamed and cancellable responses, model/session/token tracking, bounded project-aware blog tools, and localized conversation management in the Chat workspace. Allowlisted render tools add persistent native cards, charts, forms, lists, metrics, mind maps, tables, and tabs without executing assistant-provided HTML or JavaScript.
 - SSH-agent-based SCP or rsync publishing.
 - Integrated Git workflow with repository initialization, Git LFS image tracking, status and diffs, branch/file history, commits, remotes, cancellable fetch/pull/push, and post-pull filesystem reconciliation; network actions respect airplane mode.
-- Site, media, and translation validation plus `ruds://new-post` Blogmark capture and Lua transforms; captures open directly in the post editor and defer automatic translation until an explicit save or publish. bDS2 keeps its separate `bds2://` bookmarklet protocol.

 RuDS uses no JavaScript application runtime and loads no CSS or JavaScript from CDNs. The preview is served by the Rust application and displayed by the operating-system webview.
