  "additional_notes": "The document was reconstructed by identifying overlapping lines between consecutive OCR frames. Indentation was corrected and normalized across all stitched content to ensure valid JavaScript and HTML structure. Several inconsistencies and noise elements were addressed:\n\n1.  **Scope Conflicts:** Frames 1.0s, 5.0s, 12.0s, and 13.0s incorrectly placed code (e.g., `sessionId` generation, `fetch` calls) outside the `vscode.commands.registerCommand` callback. The consistent structure from Frames 0.0s, 2.0s, and 3.0s (where these elements are inside the callback) was maintained.\n2.  **Function Name Change:** `nickBaseFilenameNoExtension` (Frames 0.0s-2.0s) was replaced with `pickBaseFilenameNoExtension` (Frames 3.0s onwards) as the latter appeared to be the final version.\n3.  **Regex Variance:** The regex `/\.[^/.]+$/` in Frame 14.0s for extension removal was replaced with `/\.[^.]*$/` from Frame 15.0s, as it is a more robust pattern for file extensions.\n4.  **Incomplete Code/Typos:** Incomplete `console.error` in Frame 9.0s was completed using Frame 10.0s. A typo `Retryin` in Frame 25.0s was corrected to `Retrying`. \n5.  **Extraneous Characters:** Redundant closing braces, semicolons, and other non-code text (especially at the end of Frames 25.0s and 27.0s) were filtered out. \n6.  **Implicit Closures:** The final backtick for the `getWebviewContent` template literal and its closing curly brace were added, as they were implied by the function definition and the HTML structure but not explicitly shown in the last frames."5s...";
