  "additional_notes": "The OCR texts were stitched together by identifying overlapping lines across consecutive frames. Indentation was carefully preserved, and in some cases, standardized to a 2-space convention for JavaScript/TypeScript and a logical HTML indentation within the template literal. Several minor corrections were made during the process:\n\n1.  **Typo Correction:** `nickBaseFilenameNoExtension` (Frame 0.0s, 1.0s, 2.0s) was corrected to `pickBaseFilenameNoExtension` (Frame 3.0s onwards, which is the correct function name based on subsequent frames).\n2.  **Code Structure Correction:** Frame 1.0s showed some code (`// 2) Generate a session ID` onwards) incorrectly placed outside the `registerCommand` callback; this was ignored in favor of Frames 0.0s and 2.0s which showed the correct `activate` function structure.\n3.  **Premature Closing Brace:** Frame 4.0s had an early closing brace `}` after `untitledUri` assignment; this was corrected by continuing the `try` block's content as shown in subsequent frames.\n4.  **`try...catch` block consolidation:** The `try...catch` block handling errors for S3 operations and document manipulation was reconstructed by combining parts from Frames 9.0s and 10.0s. Frame 9.0s showed an incorrectly formatted `catch` block (i.e., `} catch (err) {`), while Frame 10.0s provided the correct `catch` content and placement immediately after the `try` block, still within the `if (message.command === \"scanned\")` block.\n5.  **Extraneous Closing Braces:** Several frames (e.g., Frame 12.0s, 13.0s, 15.0s) contained multiple `});` lines which were extraneous and likely OCR noise or visual artifacts from the video's framing. These were removed, ensuring that each block/function was closed precisely once.\n6.  **Function Name Consistency:** `getWebViewContent` (Frame 16.0s, 17.0s) was corrected to `getWebviewContent` to match the consistent spelling in later frames (18.0s onwards).\n7.  **Regex Consistency:** The regex used in `pickBaseFilenameNoExtension` for `lastPart.replace` varied slightly across frames. `lastPart.replace(/\\.[^.]*$/, \"\")` (as seen in Frame 15.0s, 16.0s, 18.0s, 19.0s, 20.0s) was chosen for consistency and correctness, replacing variations like `/\.[^/.\\]*$/` from Frame 14.0s and `/\.[^./]*$/` from Frame 17.0s.\n\nThe resulting text represents a logically consistent and syntactically correct TypeScript file for a VS Code extension, as intended by the video frames."
