  "additional_notes": "The OCR outputs were stitched sequentially, identifying overlapping lines to avoid duplication. Indentation was normalized to 2 spaces throughout the document for consistency. Several ambiguities and minor inconsistencies were resolved:\n\n1.  **Function Name Discrepancy**: `nickBaseFilenameNoExtension` (frames 0.0s, 1.0s, 2.0s) was standardized to `pickBaseFilenameNoExtension` as seen in later frames (3.0s onwards), assuming `pick` is the final correct name.\n2.  **`fetch` `catch` Block Style**: The `catch` block for `fetch(\"http://localhost:3000/init-session\"` varied between a single-line arrow function and a multi-line block. The multi-line block format was chosen for consistency and readability.\n3.  **Error Handling (`try...catch`)**: The `try...catch` block within `panel.webview.onDidReceiveMessage` evolved across frames (from a generic `catch (e)` to a more specific `catch (err) { console.error(err); }` and finally to a detailed `catch (err) { console.error(\"[Extension] Error fetching data from S3: \", err); vscode.window.showErrorMessage(\"Failed to load file from S3.\"); }`). The most detailed version was used.\n4.  **`getWebviewContent` Function Name**: `getWebviewContent` was occasionally OCR'd as `getWebViewContent` (capital 'V'). The lowercase 'v' version (`getWebviewContent`) was used consistently.\n5.  **Regex in `pickBaseFilenameNoExtension`**: The regex to remove the file extension varied slightly (e.g., `/\\.[^/.\\\\]*$/`, `/\\.[^.]*$/`, `/\\.[^./]*$/`). The simpler `/\.[^.]*$/` was chosen for consistency as it appeared in multiple instances.\n6.  **HTML Template Literal `return` syntax**: Frame 22.0s incorrectly showed `return (` instead of `return \`` for the HTML template literal. This was corrected.\n7.  **Stray OCR Artifacts**: Various partial lines, redundant closing braces/parentheses, and malformed code snippets (e.g., at the beginning of frames 5.0s, 10.0s, 12.0s, 13.0s, 14.0s, 15.0s) were identified as OCR noise or loss of context and filtered out to maintain a logical and syntactically correct flow."
