  "additional_notes": "The document was reconstructed by identifying overlapping lines between consecutive OCR frames. Key decisions and observations during the process include:\n\n1.  **Code Structure Consistency:** Several frames (e.g., 1.0s, 4.0s, 10.0s, 11.0s) showed incomplete or syntactically incorrect code snippets (e.g., missing closing brackets, truncated `vscode.window.createWebviewPanel` parameters, a `return (` syntax error, `if (message.command === \"scanned\")` block missing in some `onDidReceiveMessage` snippets). These were reconciled by adopting the most complete and syntactically valid structure observed across frames, prioritizing logical flow over literal (and sometimes erroneous) OCR output.\n2.  **Function Naming:** The function `pickBaseFilenameNoExtension` was initially `nickBaseFilenameNoExtension` in frame 0.0s. This was corrected to `pickBaseFilenameNoExtension` as it appeared in later, more complete definitions. Similarly, `getWebViewContent` in some frames was standardized to `getWebviewContent` to match its usage in the `activate` function and more common JavaScript naming conventions.\n3.  **Regex Evolution:** The regular expression used within `pickBaseFilenameNoExtension` evolved across frames (`/\\.[^/.]+$/` in 14.0s, `/\.[^.]*$/` in 15.0s, `/\.[^/.]*$/` in 17.0s). The `/\.[^/.]*$/` regex was chosen as it appears to be the most robust and latest version.\n4.  **Error Handling (`catch` blocks):** The formatting and content of `catch` blocks (especially for the `fetch` calls and the inner `try-catch` within `onDidReceiveMessage`) varied or were truncated in some frames (e.g., 9.0s, 10.0s, 13.0s, 14.0s). These were consolidated to use the most comprehensive error messages and a consistent block style `}).catch((err) => { ... });`.\n5.  **Indentation:** The indentation varied significantly across frames and even within code blocks (e.g., 2, 4, or 6 spaces). The entire stitched response was reformatted to use a consistent 2-space indentation for all JavaScript code and a logical 2-space indentation for nested HTML elements within the template literal, as requested for "correct indentation".\n6.  **Unused Import:** The `import * as aws from \"aws-sdk\";` line was included as it was present in the initial frames, even though it wasn't explicitly used in the visible code. No content was altered or removed, aside from correcting inconsistent syntax or formatting due to OCR errors/cropping."
