Could you build this?
Partial The viewer UI and export workflow are vibe-codeable, but reading and repairing OST files means parsing the proprietary Exchange/MAPI binary format, which requires specialized file-format expertise.
What it would actually take: A real version needs a parser for the OST binary structure (PST/OST MAPI property trees, B-trees, and encryption in newer versions), which can start from open-source projects such as libpst or libfreefile. Corrupt-file recovery and handling of newer Outlook versions require low-level binary expertise and extensive test files. Building on existing libraries cuts the work, but the parser is the hard part.
