A tool can be replaced, but a run you kept in a format only one tool reads is a run you&rsquo;ll lose eventually. So the instance format is open JSON, written down in full in <a href="https://github.com/codeinstances/codeinstances/blob/main/docs/FORMAT.md">FORMAT.md</a> for anyone who wants to read or write instances with their own tools.</p> <p>Its name is <code>codeinstances/0</code>, and that string is the first member of every file. A reader that sees a format version it doesn&rsquo;t know has to refuse the file, and readers ignore members they don&rsquo;t recognise. A file that holds the same member twice, or a known member spelled in another case, is refused. That&rsquo;s how the format can grow without breaking files that already exist.</p>
