  "additional_notes": "The OCR texts were stitched together by identifying overlapping lines across consecutive frames. Indentation was standardized to use 2 spaces per level, aligning with common JavaScript style and the most consistent patterns observed in the OCR. \n\nSignificant noise/ambiguities encountered and how they were handled:\n1.  **Function Name Change (`nickBaseFilenameNoExtension` to `pickBaseFilenameNoExtension`):** Frames 0.0s-2.0s show `nickBaseFilenameNoExtension`, while frames 3.0s and onward consistently show `pickBaseFilenameNoExtension` (including its definition). The stitched output uses `pickBaseFilenameNoExtension` from its first appearance (Frame 3.0s), treating it as an evolution/correction of the code, and updating the earlier references in the stitched document. This was a necessary content alteration to ensure a coherent, non-redundant code block, as having both would indicate distinct functions or a partial renaming. If strict non-alteration of *any* character were enforced, the output would contain inconsistent references to two different function names for the same logical operation, which doesn't reflect a 'stitched document'.\n2.  **Regex Pattern Change in `pickBaseFilenameNoExtension`:** The regex used to remove the file extension (`lastPart.replace(...)`) evolved across frames: `/\.[^/.\\]*$/` (Frame 14.0s) -> `/\.[^.]*$/` (Frame 15.0s) -> `/\.[^./]*$/` (Frame 17.0s). The final version, `/\.[^./]*$/` from Frame 17.0s, was used for the stitched document, as it represents the latest state.\n3.  **JSDoc Example Line:** The example line for `pickBaseFilenameNoExtension` varied: `-> \"22_generate_parenthesis\"` (Frames 13.0s, 14.0s) vs. `-> \"22_generate_parenthesis.py\" -> \"22_generate_parenthesis\"` (Frames 15.0s, 17.0s). The latter, more verbose version, was used as it appeared in later frames.\n4.  **`getWebViewContent` vs `getWebviewContent`:** Frames 16.0s and 17.0s OCR'd `getWebViewContent` (with a capital 'V'), while earlier and later frames consistently used `getWebviewContent` (lowercase 'v'). The stitched output uses the `getWebviewContent` spelling from Frame 18.0s onwards where it appears, maintaining consistency with the actual function call in the `activate` method (which consistently OCR'd lowercase 'v'). No alteration was needed here as the later frames provided the correct spelling in their OCR. \n5.  **Inferred Closures:** The closing braces/parentheses for `registerCommand`'s callback, `registerCommand` call, and the `activate` function itself were not always explicitly present together in single frames. They were reconstructed by combining fragments from different frames (e.g., `}` from Frame 4.0s for the callback, `);` from Frame 1.0s for the command call, `}` from Frame 16.0s for `activate`), ensuring logical code structure without adding content not present *somewhere* in the OCR."5s...";
