Follow the guide to enable codebase context checks.

Objective: Ensure all identifiers clearly express their purpose and intent, making code
self-documenting

Objective: To prevent the leakage of sensitive system information through error messages while
providing sufficient detail for internal debugging.

Objective: To ensure logs are useful for debugging and auditing without exposing sensitive
information like PII, PHI, or cardholder data.

Status: Passed

Objective: Ensure comprehensive error handling that provides meaningful context and graceful
degradation

Status:
Missing error handling: The clipboard write operation for copying message/code text does not handle failures (no
.catch/fallback), which can silently fail in unsupported browsers or restricted contexts.

let text = message?.rich_content?.message?.text || message?.text || '';
if (message?.rich_content?.message?.rich_type === RichType.ProgramCode) {
	text = message?.rich_content?.message?.code_script || text;
}

navigator.clipboard.writeText(text).then(() => {
	setTimeout(() => {
		copyClicked = false;
	}, 800);
});

Objective: To create a detailed and reliable record of critical system actions for security analysis
and compliance.

Status:
No audit events: The new code-viewing interaction (opening the code script modal) does not emit any
auditable event, which may be required depending on whether viewing message content is
considered a critical action in your audit policy.

/**
 * @param {any} e
 * @param {any} message
 */
function openCodeScriptModal(e, message) {
	e.preventDefault();

	codeScript = message?.rich_content?.message?.code_script || '';
	codeLanguage = message?.rich_content?.message?.language || 'python';
	isOpenCodeScriptModal = true;
}

function toggleCodeScriptModal() {
	isOpenCodeScriptModal = !isOpenCodeScriptModal;
	if (!isOpenCodeScriptModal) {
		codeScript = '';
		codeLanguage = '';
	}

Objective: Ensure all data inputs are validated, sanitized, and handled securely to prevent
vulnerabilities

Status:
Untrusted content display: The new modal displays message?.rich_content?.message?.code_script directly in CodeScript,
so a review is needed to confirm that handling untrusted/user-generated text in the editor
cannot lead to XSS/DOM injection via the CodeMirror wrapper configuration.

	codeScript = message?.rich_content?.message?.code_script || '';
	codeLanguage = message?.rich_content?.message?.language || 'python';
	isOpenCodeScriptModal = true;
}

function toggleCodeScriptModal() {
	isOpenCodeScriptModal = !isOpenCodeScriptModal;

		codeLanguage = '';

The CodeScript component's extensions are set in onMount, making it non-reactive
to language prop changes. Refactor this logic into a reactive declaration ($:)
to ensure the editor updates dynamically.

Examples:

    onMount(() => {
        if (language === 'python') {
            extensions = [
                python(),
                indentService.of((context, pos) => {
                    const prevLine = pos > 0 ? context.state.doc.lineAt(pos - 1) : null;
                    if (prevLine) {
                        const prevText = prevLine.text;
                        const match = prevText.match(/^(\s*)/);
                        const baseIndent = match ? match[1].length : 0;

Solution Walkthrough:

Before:

<script>
    export let language = 'python';
    let extensions = [];

    onMount(() => {
        if (language === 'python') {
            extensions = [
                python(),
                ...baseExtensions
            ];
        } else if (language === 'javascript') {
            extensions = [
                javascript(),
                ...baseExtensions
            ];
        }
    });
</script>

After:

<script>
    export let language = 'python';
    let extensions = [];

    $: {
        if (language === 'python') {
            extensions = [
                python(),
                ...baseExtensions
            ];
        } else if (language === 'javascript') {
            extensions = [
                javascript(),
                ...baseExtensions
            ];
        }
    }
</script>

Replace the header prop on the Modal component with the component for correct
title rendering and close button functionality.

src/lib/common/modals/PlainModal.svelte [23-36]

 <Modal
     class={containerClasses}
     style={containerStyles}
     fade
     size={size}
     isOpen={isOpen}
-    header={title}
     toggle={() => toggleModal()}
     unmountOnClose
 >
+    <ModalHeader toggle={toggleModal}>{title}</ModalHeader>
     <ModalBody>
         <slot />
     </ModalBody>
 </Modal>

Initialize the selectedLang variable by reading from localStorage or setting a
default value. This ensures the dropdown displays the current language upon
loading.

src/lib/common/dropdowns/LanguageDropdown.svelte [12-13]

 /** @type {string} */
-let selectedLang;
+let selectedLang = localStorage.getItem("I18N_LANGUAGE") || 'en';
 
+onMount(() => {
+  // ensure i18n is set consistently
+  setupI18n({ withLocale: selectedLang });
+});

Initialize the extensions array with baseExtensions to ensure the CodeMirror
editor always has a baseline set of features, even for unsupported languages.

src/lib/common/shared/CodeScript.svelte [33-63]

 /** @type {import("@codemirror/state").Extension[]} */
-let extensions = [];
+let extensions = [...baseExtensions];
 
 onMount(() => {
     if (language === 'python') {
-        extensions = [
+        extensions.push(
             python(),
             indentService.of((context, pos) => {
                 const prevLine = pos > 0 ? context.state.doc.lineAt(pos - 1) : null;
                 if (prevLine) {
                     const prevText = prevLine.text;
                     const match = prevText.match(/^(\s*)/);
                     const baseIndent = match ? match[1].length : 0;
 
                     // Check if previous line ends with : (control structure)
                     if (prevText.trimEnd().endsWith(':')) {
                         return baseIndent + 4;
                     }
                     return baseIndent;
                 }
                 return 0;
-            }),
-            ...baseExtensions
-        ];
+            })
+        );
     } else if (language === 'javascript') {
-        extensions = [
-            javascript(),
-            ...baseExtensions
-        ];
