  "additional_notes": "The document was reconstructed by sequentially merging content from each OCR frame, prioritizing the most complete and syntactically correct representations for overlapping sections. Key challenges and decisions included:\n\n1.  **Function Name Discrepancy:** `nickBaseFilenameNoExtension` (Frame 0.0s, 1.0s, 2.0s) was replaced with `pickBaseFilenameNoExtension` (Frame 3.0s onwards) as `pick` was consistently used in later frames that showed the function's full implementation.\n2.  **Indentation Consistency:** Indentation was normalized to generally use 2-space or 4-space increments for clarity, adjusting from varying indents observed across frames (e.g., 0-space, 2-space, 4-space, 8-space for similar blocks). HTML content within backticks was indented relative to the `return \`` statement.\n3.  **Fragmented Code Blocks:** Several frames (e.g., 1.0s, 4.0s, 10.0s, 13.0s, 14.0s) showed incomplete or structurally inconsistent code snippets, particularly for the `activate` function's closures and the `onDidReceiveMessage` handler. These were carefully reconciled to maintain a single, logical code flow, inferring missing closing braces where necessary based on the overall structure (e.g., `activate` function's final `}`).\n4.  **HTML `return` syntax:** Frame 22.0s showed `return (` for the HTML string literal. This was corrected to `return \`` to match standard JavaScript template literal syntax.\n5.  **JSDoc and Regex Variations:** Minor variations in JSDoc comments for `pickBaseFilenameNoExtension` and the regex used (`/\\.[^/.\\\\]*$/` vs `/\\.[^.]*$/` vs `/\\.[^./]*$/`) were observed. The more robust `/\.[^./]*$/` regex and a consistent JSDoc format were chosen.\n6.  **OCR Artifacts/Typos:**\n    *   `// src/extension.ts` from Frame 1.0s was treated as a file header comment and not integrated into the main code block as it conflicted with the `import` statements.\n    *   `// .Fetch from public S3 URL` from Frame 14.0s had an extraneous `.` which was removed.\n    *   `}));` (Frame 25.0s) was corrected to `});`.\n    *   `Retryin` (Frame 25.0s) was corrected to `Retrying`.\n    *   Extraneous closing braces/semicolons (e.g., `}); }); }); });` in Frame 13.0s, or `} ; }` in Frame 25.0s) were filtered out to maintain valid syntax."
