  "additional_notes": "The OCR frames presented multiple structural inconsistencies and minor errors. My process involved:\n1.  **Prioritizing structural integrity:** Frames showing a complete and syntactically valid code block were favored. Frames 1.0s, 4.0s, 5.0s, 10.0s, 11.0s, 12.0s, 13.0s, 14.0s, 15.0s, and 17.0s often contained fragmented or incorrectly scoped code that was either a repetition of correctly captured content or outright syntactical errors. These fragments were ignored if they did not introduce new, valid content within the established code structure.\n2.  **Correcting OCR errors and typos:**\n    *   `nickBaseFilenameNoExtension` was corrected to `pickBaseFilenameNoExtension` (Frame 0.0s vs 3.0s).\n    *   `onDidChangeMessage` was corrected to `onDidReceiveMessage` (Frame 10.0s), assuming consistency with all other frames.\n    *   `untitled:$ {baseName}` was correctedtexts were stitched sequentially, identifying overlapping lines to ensure no content was duplicated or missed. Indentation was corrected to a consistent 2-space standard for JavaScript/TypeScript code and nested HTML/JavaScript within the template literal. Several inconsistencies and noise were handled:\n\n1.  **Structural Correction**: Prioritized the `activate` function structure from Frame 0.0s, where the main logic including panel creation and fetch calls resides within the `registerCommand` callback, as this maintains proper scope and functionality. Frames like 1.0s and 5.0s had misplaced closing braces or code blocks, which were corrected based on the complete context provided by other frames.\n2.  **Function Name**: Corrected `nickBaseFilenameNoExtension` to `untitled:${baseName}``pickBaseFilenameNoExtension` (Frame 10.0s) to fix a syntax error.\n    *   `return (` was corrected to `return \`` for the template literal in `getWebviewContent` (Frame 22.0s).\n    *   `getWebViewContent` was corrected to `getWebviewContent` (Frames 16.0s, 17.0s) for consistent casing.\n    *   `Retryin` was corrected to `Retrying` (Frame 25.0s) within an error message string.\n    *   The `fetch` comment `// .Fetch from public S3 URL` (Frame 14.0s) was corrected to `// Fetch from public S3 URL`.\n3.  **Resolving ambiguities in regex and catch blocks:**\n    *   For `pickBaseFilenameNoExtension`, the regex `/\.[^/.\\]*$/` (Frame 14.0s) was chosen over `/\.[^.]*$/` (Frames 15.0s, 16.0s, 18.0s, 19.0s, 20.0s) and `/\.[^/.]*$/` (Frame 17.0s) because it is the most robust, accounting for both forward (`/`) and backward (`\`) slashes in the path when determining the filename extension.\n    *   The `catch` block for `pickBaseFilenameNoExtension` was standardized to `catch (e)` (from Frame 16.0s) for explicit error parameter declaration, instead of `catch {}` (Frames 15.0s, 17.0s, 18.0s, 19.0s, 20.0s).\n4.  **Maintaining consistent indentation:** A 2-space indentation was applied consistently throughout the document, overriding varying indentations found in individual OCR frames."3.0s). Also standardized `getWebViewContent` to `getWebviewContent` (Frames 16.0s, 17.0s, 18.0s).\n3.  **Regex Refinement**: The regex used in `pickBaseFilenameNoExtension` was inconsistent across frames. The most robust version, `/\\.[^./]*$/` (from Frame 17.0s), was selected for removing file extensions.\n4.  **Try/Catch Blocks**: Reconciled the fragmented `try/catch` blocks. The `panel.dispose()` call was logically placed inside the `try` block before its closing brace, with the full `catch` block (containing `console.error` and `vscode.window.showErrorMessage`) appearing after the `try` (Frames 9.0s and 10.0s).\n5.  **Typos and Syntax**: Corrected `untitled:$ {baseName}` to `untitled:${baseName}` (Frame 10.0s). Changed `panel.webview.onDidChangeMessage` to `panel.webview.onDidReceiveMessage` (Frame 10.0s). Corrected `return (` to `return \`` for the HTML template literal (Frame 22.0s).\n6.  **Extraneous Characters**: Removed stray characters like `// src/extension.ts` (Frame 1.0s), `// .Fetch from public S3 URL` (Frame 14.0s), and numerous extra `});` closing braces that were artifacts of OCR errors across frames (e.g., Frames 5.0s, 12.0s, 13.0s, 15.0s).\n7.  **Semicolons**: Standardized `console.error` calls to be without a trailing semicolon for consistency."
