+# Content Safety Violation Messages
+
+Implemented in version: **0.250.061**
+
+Related config.py version update: `application/single_app/config.py` is **0.250.061** for this implementation.
+
+## Overview
+
+Administrators can configure the Markdown message shown when Azure Content Safety blocks a chat message. They can also choose whether the response includes trigger information such as block reasons, detected categories with severity, and blocklist matches.
+
+## Dependencies
+
+- Content Safety must be enabled in Admin Settings.
+- The existing local `marked` and `DOMPurify` assets render and sanitize the saved Markdown in chat.
+
+## Technical Specifications
+
+- `content_safety_violation_message` stores the administrator-authored Markdown template.
+- `content_safety_include_trigger_information` controls whether Content Safety details are appended to the message.
+- The default message is `Your message was blocked by Content Safety.` and trigger information is enabled by default, preserving previous behavior.
+- Blank or missing templates fall back to the default message, and saved templates are limited to 3,000 characters.
+- Normal and streaming chat requests call the same backend formatter before persisting and returning a `safety` message.
+- The chat UI renders safety messages through `DOMPurify.sanitize(marked.parse(...))`; no remote browser assets are added.
+- The editor refreshes after the hidden Safety tab becomes visible, and Markdown-only edits enable Save Settings and synchronize to the submitted form value.
+
+## Usage Instructions
+
+1. Open **Admin Settings** and enable Content Safety.
+2. Use the standard Markdown toolbar in **Safety Violation Message** to format the desired text.
+3. Keep **Include Trigger Information** selected to append the block reason, categories, severities, and blocklist matches. Clear it to show only the configured message.
+4. Save the settings. Newly blocked chat messages use the saved configuration.
+
+## Testing and Validation
+
+- `functional_tests/test_content_safety_violation_message.py` validates the Markdown editor toolbar, default output, Markdown template preservation, trigger-information suppression, and blank-template fallback.
+- Admin Settings validation verifies message normalization, seed defaults, and the form controls.
+- Version was updated in `application/single_app/config.py` to `0.250.061` for traceability.
+
+## Known Limitations
+
+- The setting applies to text-chat Content Safety blocks. Image-generation moderation messages continue to use their existing dedicated copy.
+- Saved messages affect newly created safety messages; historical conversation messages retain the text stored when they were created.
