 Publishing in RuDS is a staged process: publish content locally, generate or validate-and-apply site changes, commit the result, then deploy when ready.
 
-Full generation builds the entire static site. Site validation detects missing, extra, and updated routes so RuDS can re-render only what changed. This is the practical incremental workflow for most daily editorial changes.
+Full generation builds the entire static site and skips files whose tracked content hash is unchanged. Use **Blog → Force Render Site** (Command/Ctrl+Shift+R) when every generated file must be rewritten regardless of its stored hash. Site validation detects missing, extra, and updated routes so RuDS can re-render only what changed. This is the practical incremental workflow for most daily editorial changes.
 
 When blog languages are configured, generation produces language-aware route trees, per-language feeds, and alternate language metadata.
 
 ### Key takeaways
 
 - Full generation produces the complete site.
+- Force Render Site rewrites the complete site and search index without relying on stored hashes.
 - Validate and Apply is the efficient daily workflow for incremental publishing.
 - Public Base URL must be set before generation.
 - Commit generated output before deploying for recoverability.

 - A fully localized Ratatui terminal workspace, available locally through `bds-cli tui`/`BDS_MODE=tui` and remotely through authenticated SSH shell sessions, with shared post/template/script editing and publishing, project/search/command overlays, settings, tags, Git, reports, task progress, live multi-client locale updates, and airplane-mode AI gating.
 - `bds-cli server` hosting the shared application engines over a loopback-by-default, public-key-only SSH service, with restrictive private key material, live authorization updates, terminal-session transport, CLI-change synchronization, ordered domain/task events, and native desktop remote-project selection.

 - Optional one-shot AI translation, description, analysis, taxonomy, and language-detection operations run in background tasks with editor-level waiting indicators, using provider-portable JSON-only requests through independent online and local OpenAI-compatible profiles. Each profile has secure credentials, persistently discovered chat/title/image model selections, explicit tool/vision overrides, chat testing, and restart-persistent status-bar airplane-mode routing.
 - 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.
