  "additional_notes": "The document was reconstructed by identifying overlapping lines between consecutive OCR frames and removing duplicates. Significant effort was made to correct indentation to conform to standard JavaScript/TypeScript practices, especially for nested blocks and HTML string literals. Several OCR errors were inferred and corrected for logical and syntactical validity:\n\n1.  **Function Name Consistency**: The function `nickBaseFilenameNoExtension` (seen in frames 0.0s, 1.0s, 2.0s) was corrected to `pickBaseFilenameNoExtension` at its call site. This was done because subsequent frames (3.0s onwards) and the function's definition consistently use `pickBaseFilenameNoExtension`. This correction ensures the code is syntactically valid and consistent with the function's definition.\n2.  **`getWebviewContent` Case**: The function `getWebViewContent` (capital 'V' in frames 16.0s, 17.0s) was standardized to `getWebviewContent` (lowercase 'v') to match its call site in the `activate` function and more consistent occurrences in other frames containing the HTML content. This is likely an OCR misinterpretation of the casing.\n3.  **HTML String Literal**: In frame 22.0s, `return (` was identified as an OCR error and corrected to `return \`` to correctly initiate the multiline HTML string literal.\n4.  **Try-Catch Structure Inference**: The `onDidReceiveMessage` handler's `try-catch` blocks required significant inference. Frames 9.0s and 10.0s/11.0s presented different `catch` block structures. The final reconstruction incorporates a nested `try-catch`: an inner one specifically for the `if (message.command === \"scanned\")` block's S3 operations, and an outer `try-catch` encompassing the entire `onDidReceiveMessage` callback to handle broader errors, based on the `[Extension] Error...` messages in later frames. This required adding an explicit `try {` around the `if` statement and adjusting the scope of the catch blocks.\n5.  **Redundant Closing Braces**: Several frames, especially 13.0s, contained redundant or misplaced closing braces (`});})`) which were filtered out as OCR noise or partial/misaligned text captures. The final structure adheres to proper JavaScript scoping."
