PlatPhorm Update Timestamp Backfill

A PlatPhorm Update Timestamp Backfill is a PlatPhorm News dictionary concept for making PlatPhorm stories portable across RSS, Atom, APIs, and article cards. It treats the last-modified story signal as a structured article-listing or network-graph concern, and it adds older articles to a feed without breaking order. In practice, it helps editors, services, and AI agents keep title, canonical URL, source, image, summary, and timestamps aligned across every listing surface.

“Use the PlatPhorm Update Timestamp Backfill when serializing a story into RSS while keeping its canonical article URL and preview image intact so the article listing, source metadata, and agent-facing context stay aligned.”
