 - SQLite and filesystem persistence with byte-canonical bDS2 frontmatter, media sidecars, metadata JSON, and OPML menus; rebuild; bidirectional metadata diff/repair including project categories and publishing preferences; stale post-path cleanup on republish; bDS2-compatible checksums and 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 Tags workspace manages tags and category settings; its category table includes the main language and every configured translation, whose titles are used by the matching category archives.
 - 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.
 - Headless `bds-cli` automation for rebuild/repair/render, publishing and Git sync, post/media/gallery creation, effective shared settings with secret-presence redaction, projects, utility Lua tasks, JSON I/O, airplane-mode AI routing, and guarded launcher installation from Settings → Data or `bds-cli install`.
