The series footer used to hardcode which model I was using for code assist, which went stale the moment a new one shipped. I added an optional model field to the posts schema and taught the remark-series plugin to substitute a {{model}} placeholder in the footer template with each post’s own value. Now the panel reads “at the time of writing” and names whatever model that particular post was written with.

To keep the data honest, the plugin throws at build time if a series footer references {{model}} but a post in that series is missing the frontmatter, so I can’t accidentally ship a post without recording which model drove it.
