  "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."          }\n        }\n\n        checkForScan();\n      </script>\n    </body>\n    </html>\n  `;\n}",
  "additional_notes": "Stitched frames together by identifying longest common overlapping lines and appending unique new content. Applied a consistent 2-space indentation for TypeScript/JavaScript code and appropriate HTML indentation within the template literal. Resolved several content evolution and inconsistencies:\n1.  Ignored Frame 1.0s' structural divergence as it appeared to be an anomaly compared to other frames (0.0s, 2.0s, 3.0s, etc.) which maintained a consistent `activate` function structure where most logic is within the `registerCommand` callback.\n2.  Updated function name from `nickBaseFilenameNoExtension` (Frame 0.0s) to `pickBaseFilenameNoExtension` (Frame 3.0s).\n3.  Updated regex pattern in `pickBaseFilenameNoExtension` across frames: from `/\.[^/.\\]*$/, \"\"` (Frame 14.0s) to `/\.[^.]*$/, \"\"` (Frame 15.0s), and finally to `/\.[^./]*$/, \"\"` (Frame 17.0s), applying the latest version encountered.\n4.  Standardized the `getWebviewContent` function definition name to `getWebviewContent` (matching its call site in `activate` and the explicit definition in Frame 18.0s), resolving a conflict with `getWebViewContent` seen in Frame 16.0s/17.0s.\n5.  Corrected inconsistent indentation and removed seemingly extraneous closing braces/parentheses that appeared to be OCR errors (e.g., in Frame 4.0s, 13.0s, 22.0s), ensuring the final output conforms to valid JavaScript/HTML syntax.\n6.  Corrected the HTML template literal's opening in Frame 22.0s, where it appeared as `return (` instead of `return ``."
