fix: handle missing message in assistant generation telemetry

getGenerationTelemetry threw NOT_FOUND when the stored message id did
not match a persisted message (e.g. the assistant message is still
streaming or was just removed), surfacing as a failed tRPC query in the
console. Return an empty complete result instead, matching the existing
graceful handling for providers without OpenRouter telemetry, and only
fire the client query once both threadId and messageId are available.

+# Assistant
+
+Administrators can configure the instance-wide AI assistant from **Management → Assistant**.
+It is available to signed-in users from the user menu, with `Shift + A`, and from the
+`Cmd/Ctrl + K` command menu. **Ask Homarr Assistant** is always available as a local result in the default
+search. Selecting it with an existing query sends that query in the background; selecting it without a
+query turns the command-menu search field into a prompt composer. Press
+`Enter` to send the prompt in the background without opening the conversation. The search field receives
+focus whenever the command menu opens, including when it is opened by an assistant tool. Sending from the
+command menu preserves any draft in the expanded conversation. The local result is temporarily disabled while
+the assistant is responding or waiting for an approval.
+
+While a response is running, a compact activity bar appears at the bottom of the page and the user-menu
+avatar shows a thinking indicator. The activity bar can be opened to follow the response. Completed
+responses add an unread count to the user menu until they are opened or dismissed. The expanded
+conversation has a minimize action that returns it to the activity bar without interrupting a response.
+The transcript follows streamed output while it is already at the bottom, including fast responses. Scrolling
+up releases that follow state until **Scroll to latest** is selected or the user returns to the bottom.
+
+`Shift + A` opens the compact conversation panel directly. The shortcut is ignored while typing in text
+fields, selectors, and editable content.
+
+The **Assistant** board widget embeds the same persisted conversation and full interaction surface directly
+on a dashboard. By default it follows the current conversation. Widget settings can instead pin a specific
+conversation; the conversation picker stays hidden until **Pinned conversation** is selected.
+
+When the assistant is unavailable, its command-menu result remains visible but disabled and explains that
+an administrator must configure and enable it.
+
+## Configure a model provider
+
+Homarr includes presets for OpenRouter, OpenAI, Anthropic Claude, Google Gemini, xAI, Groq, Mistral AI,
+DeepSeek, Together AI, Ollama, and LM Studio. Provider icons make the presets easy to identify. A custom
+preset connects any other service that implements the OpenAI Chat Completions API.
+
+The provider list also shows **Homarr — Coming soon** as a disabled option. The future service will be a
+Homarr-hosted OpenRouter proxy with the same model discovery, tool-calling, and server-tool features. Keeping
+it visible reserves a clear place for that service without making an unavailable backend selectable today.
+
+The management page presents setup as three compact sections: provider and endpoint, credentials, then
+model and availability. A status summary at the top shows whether the connection is ready, whether a key
+is protected, which model is selected, and whether users can open the assistant.
+
+1. Choose a provider preset or **Custom endpoint**, then confirm the API base URL. It usually ends in `/v1`.
+2. Add an API key if the service requires bearer authentication. Additional authentication or routing
+   headers are available in the collapsed advanced section.
+3. Save the provider connection.
+4. Refresh the model list and select a discovered model. Homarr displays the friendly model name but
+   stores and sends the provider's exact model ID.
+5. Enable the assistant and save the configuration.
+
+The model discovery path defaults to `/models` and is appended to the API base URL. Leave it blank when
+the service does not expose model discovery. A manual model ID can still be used when discovery is
+disabled, unavailable, or returns no models.
+
+API keys and additional header values are encrypted in the Homarr database. They are decrypted only on
+the server for discovery and model requests, and they are never returned to the browser. Changing the
+provider or base URL clears existing credentials unless replacements are submitted with the change. This
+prevents credentials for one service from being sent to another endpoint.
+
+When a key is already stored, the page shows its protected state instead of an ambiguous empty password
+field. **Replace key** starts a two-step flow: enter the new key, then review the provider, destination,
+and impact before confirming. The existing key remains active until confirmation, and its value cannot be
+restored after replacement. Removing only the API key also requires explicit confirmation. **Remove all
+credentials** uses a separate destructive confirmation because it also clears the selected model and
+disables the assistant.
+
+:::info Container networking
+
+For a containerized Homarr installation, `localhost` refers to the Homarr container. Use a resolvable
+container name, internal DNS name, or host gateway address to reach Ollama, LM Studio, or another local
+model server.
+
+:::
+
+The configured endpoint must support streaming Chat Completions and structured tool calls for the full
+assistant experience. Model discovery alone does not guarantee tool support, except when OpenRouter
+explicitly advertises the model's `tools` capability.
+
+OpenRouter web search is an opt-in option in the model section. It registers OpenRouter's model-callable
+[`openrouter:web_search` server tool](https://openrouter.ai/docs/guides/features/server-tools/web-search)
+alongside Homarr's tools, so OpenRouter performs each search without
+exposing the stored credential to the browser. The model decides when live research is needed and can use the
+grounded results and source links in responses or dashboard notes. Homarr limits each assistant request to
+three searches with five results per search. OpenRouter charges web-search usage separately from model tokens.
+Completed responses show a compact web-search activity card when OpenRouter reports search usage. OpenRouter
+does not expose these server-side searches as ordinary client-executed tool calls, so Homarr shows the reported
+search count and the safe title and URL from each returned `url_citation` annotation instead. Citation excerpts
+stay in the provider response and are not persisted in the activity card.
+
+The option is also available for custom endpoints that forward OpenRouter's server-tools request format. This
+supports OpenRouter proxies, including the future Homarr Router provider. Leave it disabled for ordinary
+OpenAI-compatible endpoints because the `openrouter:*` tool type is not part of the standard OpenAI API.
+
+The Claude preset uses Anthropic's OpenAI SDK compatibility layer. Anthropic describes that layer as
+suited to testing and comparison rather than as its full native API; unsupported OpenAI fields may be
+ignored. Streaming responses and tool calls are supported, which are the capabilities Homarr Assistant
+uses. Choose OpenRouter or another provider when you prefer a provider-neutral production endpoint.
+
+## Conversations and tools
+
+Conversations and messages are stored per user in the Homarr database. The assistant stays out of the
+page layout until it is opened. Users can start, revisit, and delete conversations from the
+conversation menu in the floating panel.
+
+Messages support copy, edit-and-resend, response regeneration and branch navigation, Markdown export,
+and helpful/not-helpful feedback.
+Selecting text in a message exposes a quote action that carries the selected passage into the next prompt.
+Files returned by a compatible model can be downloaded directly from the message.
+Assistant responses render GitHub-flavored Markdown, including headings, links, lists, task lists, tables,
+quotes, inline code, and fenced code blocks. Line breaks are preserved, and Homarr repairs common streamed
+responses where a provider returns escaped line breaks or places a bold-label list on one line.
+Fenced `mermaid` blocks render as diagrams in the current color scheme using Mermaid's strict security mode;
+invalid diagrams fall back to their source instead of breaking the response.
+When Homarr's icon search returns an image URL, visual result tables render that actual icon in a compact
+image column instead of substituting an emoji. Assistant-provided Markdown images accept safe relative,
+HTTP, and HTTPS sources and load without forwarding the Homarr page as the referrer.
+Images up to 1 MB and text, Markdown, CSV, HTML, XML, or JSON documents up to 350 KB can be attached by
+using the paperclip or dropping files onto the composer. A request can contain up to five attachments.
+Image understanding depends on the selected model; document text is extracted locally by Homarr and sent
+as part of the prompt.
+
+Type `@` in the composer to add permission-checked context. The nested menu contains apps, integrations,
+boards, widgets, and tools available to the current user. Homarr validates every referenced ID again on
+the server before adding it to the model context. Selected references appear as compact, typed pills in the
+composer and sent message, while preserving assistant-ui's underlying directive syntax for the model. When the
+assistant cites one of those references in its own response, Homarr renders the same typed pill and uses the
+stored app or integration icon when one is available. Type `/`
+for common prompt shortcuts. Both menus support keyboard navigation and keep the active result visible while
+moving through long lists. The selector below the composer combines searchable, provider-grouped models with
+their description, context size and image-input capability, plus the thinking-level control. Model selection is
+stored on the conversation after a completed request. Thinking mode can be left on **Auto**, disabled, or set
+from minimal through high; explicit levels are sent using the AI SDK's provider-neutral reasoning setting and
+still depend on support from the chosen model and endpoint. Reasoning text is shown live when the provider
+streams it. The **Thinking** disclosure can be opened or closed without interrupting the response.
+
+Each completed response includes a circular context-window meter. Select it to open request details when
+the provider reports them: input, output, cached-input and reasoning tokens, used and remaining context,
+time to first output, total duration, output speed, agent-step timing, and cost. OpenRouter-reported cost
+is labeled as reported.
+While the next response is still streaming, the meter keeps the last completed reading for the same model and
+context capacity instead of briefly showing an incorrect zero. It switches to the new request when token usage
+arrives; incompatible model capacities are never mixed.
+OpenRouter responses request inline usage and routing metadata. When request details are opened, Homarr also
+loads the server-side generation record for each model step and briefly polls while OpenRouter finishes
+processing it. The details separate Homarr's end-to-end timing from OpenRouter's provider latency,
+generation time, and provider throughput, and can include normalized and native token counts, moderation
+latency, cache discount, fallback count, service tier, data region, BYOK status, routed provider, generation
+identifier, exact cost, and upstream inference cost. Provider credentials remain server-side; the browser
+can request only generation identifiers already stored on a conversation owned by the signed-in user and
+signed by the Homarr server for that user and conversation. Successful generation lookups are cached
+briefly so polling and multi-step requests do not repeatedly query OpenRouter for the same record.
+When a provider omits cost but model discovery includes prompt and completion pricing, Homarr labels the
+calculated value as estimated. Missing provider data is shown as not reported rather than inferred.
+
+The assistant can use the same internal tool definitions as the [Homarr MCP server](./mcp).
+Each tool call runs as the signed-in user, so normal Homarr permission checks still apply. Read-only
+procedures can run during the agent loop. Mutating procedures require an explicit approval in the
+conversation before they execute. The approval appears as a large **Approve and run** or **Deny** action;
+the assistant does not require a second typed confirmation first. Tool cards expose their status, timing,
+validated input, result, and error state without flooding the conversation with raw JSON by default.
+Common collection and widget results are summarized inline as compact responsive cards, while the full
+structured result remains available in the tool card details. Icon searches show the returned image variants,
+file formats, and repositories instead of the size of the complete icon catalog.
+
+Large tool-driven requests can use up to 32 agent steps and a larger response budget within one request, so
+multi-item dashboard changes normally finish without requiring a follow-up “Continue” message. Independent
+read-only lookups may be performed together, while every mutation still pauses for its normal approval.
+
+The assistant can create a formatted dashboard note by adding a **Notebook** widget. Ask it for a note with
+headings, lists, tasks, links, emphasis, tables, or images; it generates compatible rich-text content, shows
+the native widget configuration form and standard mutation approval, then places the widget in the next
+available dashboard position. The generated content is retained even though the Notebook content field is
+normally hidden from widget settings.
+
+Every assistant-created dashboard widget now passes through Homarr's native widget editor before it is added.
+The form fills widget defaults, validates widget-specific options, and only offers compatible integrations that
+the current user can use. Required integrations cannot be left empty, single-integration widgets cannot receive
+multiple integrations, and the reviewed values are passed unchanged into the final approval-gated mutation.
+
+Custom-widget tools let an administrator list, inspect, create, and update definitions. The custom-widget
+form's **Design with AI** action sends a focused request into the current conversation, where the assistant
+can propose the matching mutation and use the same approval controls. Existing stored secret values are
+reported only as configured/not configured and are preserved on update unless replacements are explicitly
+provided.
+
+The shield control in the conversation header can enable automatic approvals for the current conversation.
+While enabled, Homarr accepts every affirmative approval step as it arrives: protected mutations are approved,
+presented app details and board changes are used, and structured questions with an explicitly categorized
+**Confirm** answer choose that answer. Neutral choices such as selecting a board still wait for input because
+they do not have a safe affirmative default. Automatic approvals turn off when you switch conversations, and
+the shared approval tracker prevents the same call from being handled twice when both a board widget and the
+floating assistant are visible.
+
+When the assistant genuinely needs missing information or a choice, it can pause with a structured
+question. Each proposed answer is visibly categorized as **Confirm**, **Decline**, or **Option**, so the effect
+of automatic approval is unambiguous. Users can select one of the proposed answers or choose **Other** and
+enter their own response. While a question is unanswered, its controls stay in a dedicated area immediately
+above the composer instead of requiring the user to find the tool call in the transcript. The answered choice
+then remains in the conversation history.
+Submitting the answer resumes the same agent run automatically. The minimized activity bar shows the
+question or approval that needs attention and opens directly back to the request. While an answer, app
+form, or mutation approval is pending, the composer preserves its draft but does not replace the pending
+tool call with a new message. If the provider stops before an interactive tool supplies complete arguments,
+Homarr replaces the loading state with an explicit error and confirms that no change was made.
+
+App creation uses Homarr's native app form inside the conversation. The form reuses the local icon picker,
+including automatic matching and searches through the `icon.findIcons` procedure, before the final
+`app.create` approval is requested. App fields are filled only after the complete tool input has arrived, so
+streaming partial arguments cannot replace the proposed values with empty fields. The model is instructed not
+to invent external icon CDN URLs.
+
+Board appearance changes use a similar review flow. The assistant first reads the board's current settings,
+including its complete custom stylesheet, and then opens an editable form with Custom CSS, Appearance,
+Background, and General tabs. The form highlights how many fields were proposed, preserves settings the
+assistant did not change, and returns only values that differ from the current board. Custom CSS can be
+copied or restored before continuing, and Homarr warns when it contains an imported stylesheet or remote
+resource URL. Continuing from the form opens the normal mutation approval before anything is saved.
+
+Ask for changes such as “make the cards denser on my Home board,” “add a mobile CSS rule without removing
+my existing styles,” or “change the board colors and disable app status checks.” The current user must have
+modify permission on the selected board. The empty conversation includes an **Improve a dashboard** starter,
+and `/style` prepares the same guided workflow from the composer.
+
+Homarr also exposes a small set of browser-only actions to the assistant. These actions can navigate to
+safe internal routes, refresh the current view, and open Homarr interfaces such as the command menu and media request search.
+They never receive provider credentials and cannot navigate to arbitrary external URLs.
+
+After an approved mutation completes, Homarr automatically refetches active page and dashboard data so
+board items, settings, custom CSS, apps, and other visible results update without a full browser reload.
+The refresh action in the conversation header performs the same safe refetch manually. It keeps the
+conversation open while refreshing both client queries and server-rendered route data.

+
+The Assistant widget brings the same conversation available from the user menu and command menu onto a
+board. Messages, conversations, tool calls, approvals, files, mentions, model controls, reasoning controls,
+usage details, and response actions remain synchronized with the app-wide assistant.
+
+The assistant must be enabled by an administrator in **Management → Assistant**. Signed-out users and users
+on an instance without an enabled model see an unavailable state instead of a broken composer.
+
+### Adding the widget
+
+<AddingWidget />
+
+The default widget size is ten columns by four rows and automatically fits boards with fewer columns. Controls
+and labels condense as the widget becomes narrower, while the conversation remains scrollable and usable on
+touch devices. When a board layout does not provide enough height for conversation controls, the widget shows
+a compact **Open assistant** action instead of squeezing an unusable composer into the card. Increase its height
+in that layout to keep the complete conversation inline.
+
+### Configuration
+
+<WidgetConfig configuration={assistantWidget.configuration} />
+
+**Current conversation** follows whichever conversation is active in the user-menu panel, `Shift + A`, or
+the command menu. This is the default and keeps every assistant entry point synchronized.
+
+**Pinned conversation** reveals a searchable conversation selector. A pinned widget never changes the
+active conversation silently: select **Open conversation** inside the widget before continuing that thread.
+
+### Conversation features
+
+- Create, switch, rename, and delete conversations.
+- Send text and supported file or image attachments.
+- Mention permitted apps, integrations, boards, widgets, and tools with `@`.
+- Use `/` shortcuts for common dashboard tasks.
+- Review tool calls, approve mutations, and answer structured assistant questions inline.
+- Answer pending structured questions from the dock above the composer without scrolling through the conversation.
+- Enable conversation-scoped automatic approvals from the shield control to approve protected mutations, use presented form details, and choose answers categorized as affirmative without individual clicks.
+- Edit user messages and copy, regenerate, branch, quote, export, or rate responses.
+- Inspect Markdown, sources, generated files, tool results, reasoning, token use, context-window use, timing,
+  speed, provider routing, and cost.
+- Change the model and reasoning effort for the active conversation.
+- Refresh the current board from the conversation header. Approved mutations also refresh visible board data automatically.
+
+The expanded assistant and board widget use the same persisted thread runtime. A response continues in the
+background when the widget leaves the viewport or the expanded panel is minimized.

+const assistantInstructions = `You are Homarr Assistant, embedded in the user's self-hosted Homarr dashboard.
+
+Use the available Homarr tools whenever live instance data is needed. Never invent integrations, boards, apps, users, media, system status, or action results.
+
+Homarr concepts:
+- Integrations connect Homarr to services such as Sonarr, Radarr, Plex, Jellyfin, Home Assistant, download clients, DNS filters, and monitoring systems.
+- Boards are customizable dashboards. Apps are visual links on boards. Widgets show live integration data.
+- Tool inputs that require an integrationId must use an id returned by an integration discovery tool.
+- Existing Homarr permissions are authoritative. If a tool denies access, explain that the current user lacks permission without suggesting a bypass.
+
+Action rules:
+- Prefer read-only tools before actions.
+- When required information is missing or the user must choose between meaningful alternatives, call ask_user. Do not ask the question only in prose. Offer distinct choices, categorize agreement or proceeding as affirmative, refusal as negative, and unrelated selections as alternative, then leave the freeform Other answer enabled. A confirmation question must have exactly one affirmative option.
+- Mutating Homarr tools already pause for native user approval. Calling a mutation only proposes the action; it cannot execute until the user selects Approve and run. Once the requested change is sufficiently specified, call the mutation immediately so the approval UI appears.
+- A prose response such as "Please confirm if you would like me to proceed", "Would you like me to proceed?", or a parameter summary that asks for confirmation is incorrect. Never ask for a second textual confirmation before an approval-gated tool call.
+- Do not retry a denied action.
+- Before creating an app, call configure_app with the app name and every useful default you can infer, including its description, href, pingUrl, and an icon URL returned by icon_findIcons. The user reviews Homarr's native app form. Its icon picker searches Homarr's local icon repository. Use the returned values for app_create. If the user asked to place it on a board, call configure_widget afterward with kind "app" and options { appId: the returned appId }.
+- Before changing a board's custom CSS or visual and behavior settings, call board_getBoardSettings to read the current values, then call configure_board_settings with only the requested proposed changes. The user can edit the complete CSS and settings in Homarr's native form. Use its returned flat object for board_savePartialBoardSettings, which then shows the mutation approval. Never overwrite existing CSS rules unless the user explicitly requests replacement.
+- Before adding any widget to a board, call configure_widget with the target board, widget kind, proposed options, and any integration IDs selected from integration_all. Homarr's native widget editor applies defaults, validates the options, and restricts the picker to compatible integrations the user can access. Use the returned boardId, kind, options, and integrationIds exactly as the input to board_addItem. If configure_widget returns cancelled, do not add the widget.
+- To create a formatted note on a dashboard, call configure_widget with kind "notebook". Put valid Tiptap-compatible HTML in options.content and set options.showToolbar and options.allowReadOnlyCheck when useful. Use semantic paragraphs, headings, lists, task lists, blockquotes, tables, links, emphasis, and images as appropriate. Never include scripts, styles, iframes, event handlers, or unsafe URL protocols.
+- When choosing an app icon without configure_app, call the Homarr icon findIcons tool first and use one of its returned local icon URLs. Never invent a third-party icon CDN URL.
+- When a Homarr tool returns a usable image or icon URL and a visual summary helps, embed that exact URL with Markdown image syntax. App summary tables must use an Icon column such as ![Discord icon](exact-returned-url). Never replace an available returned icon with emoji, and never invent or transform image URLs.
+- Complete batch requests in the same run. Use parallel independent read-only calls when supported, reuse results, continue calling tools until every requested item has been attempted, and summarize only after the batch is complete. Do not stop after a partial batch or ask the user to type "Continue".
+- Browser tools can navigate within Homarr, open existing Homarr UI, or refresh the active view after a completed change. Never navigate to an arbitrary external URL and never refresh before a mutation finishes.
+- Keep responses concise and lead with the result. Summarize tool output instead of dumping JSON.
+- Use well-formed GitHub-flavored Markdown. Put each list item on its own line and leave a blank line before lists.
+- If configuration or a service is unavailable, say what the user or administrator can do next.
+
+Critical approval protocol: when a mutation's inputs are known, your next response must contain the mutation tool call, not a confirmation question. Homarr itself obtains approval after the tool call and before execution.`;
