         - Pay special attention to risky or abusable Lua basic-library features and global-state primitives such as `load`, `loadfile`, `dofile`, `collectgarbage`, `getmetatable`, `setmetatable`, `rawget`, `rawset`, `rawequal`, `_G`, or patterns that dynamically execute code, inspect or alter hidden state, bypass expected data flow, or make behavior harder to review.
         - If such Lua features are used in a way that could execute hidden code, mutate runtime behavior, evade review, tamper with guardrails, access unexpected files or modules, or conceal the plugin's real behavior, treat that as strong evidence for at least CAUTION and often DANGEROUS depending on impact and clarity.
         - When these risky Lua features appear, explicitly evaluate whether their usage is necessary and transparent for the assistant's stated purpose, or whether it creates an unnecessary attack surface even if the manifest otherwise looks benign.
+        - `LogInfo`, `LogDebug`, `LogWarning`, `LogError`, `InspectTable`, `DateTime` and `Timestamp` are C# helper methods that we provide and usually not necessarily DANGEROUS. Audit the usage and decide if its for Debugging only and if so mark as SAFE.
         - Mark the plugin as CAUTION only when there is concrete evidence of meaningful risk or ambiguity that deserves manual review.
         - Mark the plugin as SAFE only when no meaningful risk is apparent from the provided material.
         - A SAFE result should normally have no findings. Do not add low-value findings just to populate the array.

 When you build a plugin, start with the directory layout and the `Structure` section, then jump to the component references you actually use. The resource links at the end are the primary sources for Lua and MudBlazor behavior, and the `General Tips` section collects the practical rules and gotchas that matter most while authoring `plugin.lua`.
 
+## Minimal Example
+If you want to see a complete assistant plugin, start with `examples/translation/plugin.lua` in this folder. It mirrors the built-in translation assistant in a reduced form.
+
+This example shows:
+- `WEB_CONTENT_READER`
+- `FILE_CONTENT_READER`
+- a plain `TEXT_AREA`
+- a `DROPDOWN` for the target language
+- `PROVIDER_SELECTION`
+- `ASSISTANT.BuildPrompt(input)` for prompt assembly
+
+Treat the example as the recommended minimum viable pattern for assistant plugins, not as a feature-by-feature clone of `AssistantTranslation.razor`.
+
 ## Directory Structure
 Each assistant plugin lives in its own directory under the assistants plugin root. In practice, you usually keep the manifest in `plugin.lua`, optional icon rendering in `icon.lua`, and any bundled media in `assets/`.

 - Behavior notes:
   - For single-select dropdowns, `input.<Name>.Value` is a single raw value such as `germany`.
   - For multiselect dropdowns, `input.<Name>.Value` is an array-like Lua table of raw values.
-  - The UI shows the `Display` text, while prompt assembly and `BuildPrompt(input)` receive the raw `Value`.
+  - `input.<Name>.Display` contains the visible label for single-select dropdowns.
+  - For multiselect dropdowns, `input.<Name>.Display` is an array-like Lua table of visible labels in the same order as `Value`.
   - `Default` should usually also exist in `Items`. If it is missing there, the runtime currently still renders it as an available option.

 - Added pre-call validation to check if the selected model exists for the provider before making the request.
 - Added math rendering in chats for LaTeX display formulas, including block formats such as `$$ ... $$` and `\[ ... \]`.
 - Added the latest OpenAI models.
+- Added support for mandatory information notices in configuration plugins. Organizations can now require users to read and confirm important information before continuing in AI Studio.
 - Released the document analysis assistant after an intense testing phase.
 - Improved enterprise deployment for organizations: administrators can now provide up to 10 centrally managed enterprise configuration slots, use policy files on Linux and macOS, and continue using older configuration formats as a fallback during migration.
+- Improved transparency on the information page by showing configured mandatory notices together with their source and confirmation status.
 - Improved the profile selection for assistants and the chat. You can now explicitly choose between the app default profile, no profile, or a specific profile.
 - Improved the performance by caching the OS language detection and requesting the user language only once per app start.
 - Improved the chat performance by reducing unnecessary UI updates, making chats smoother and more responsive, especially in longer conversations.
@@ -22,12 +24,15 @@
 - Improved the logbook reliability by significantly reducing duplicate log entries.
 - Improved file attachments in chats: configuration and project files such as `Dockerfile`, `Caddyfile`, `Makefile`, or `Jenkinsfile` are now included more reliably when you send them to the AI.
 - Improved the validation of additional API parameters in the advanced provider settings to help catch formatting mistakes earlier.
+- Improved the model checks and model list loading by showing clearer error messages when AI Studio cannot access a provider because the API key is missing, invalid, expired, or lacks the required permissions.
 - Improved the app startup resilience by allowing AI Studio to continue without Qdrant if it fails to initialize.
 - Improved the translation assistant by updating the system and user prompts.
+- Improved OpenAI-compatible providers by refactoring their streaming request handling to be more consistent and reliable.
 - Fixed an issue where assistants hidden via configuration plugins still appear in "Send to ..." menus. Thanks, Gunnar, for reporting this issue.
 - Fixed an issue with chat templates that could stop working because the stored validation result for attached files was reused. AI Studio now checks attached files again when you use a chat template.
 - Fixed an issue with voice recording where AI Studio could log errors and keep the feature available even though required parts failed to initialize. Voice recording is now disabled automatically for the current session in that case.
 - Fixed an issue where the app could turn white or appear invisible in certain chats after HTML-like content was shown. Thanks, Inga, for reporting this issue and providing some context on how to reproduce it.
+- Fixed an issue where exporting to Word could fail when the message contained certain formatting.
 - Fixed security issues in the native app runtime by strengthening how AI Studio creates and protects the secret values used for its internal secure connection.
 - Fixed an issue in which the file attachment window exhibited delayed opening or generated duplicate instances on repeated activation. Thanks, Bernhard, for reporting this issue.
 - Updated several security-sensitive Rust dependencies in the native runtime to address known vulnerabilities.
