• Importing a persona file no longer replaces a character you already have. A character in the file whose key matches one on this station is now skipped by default, and the import dialog in the console and the desktop app says so and offers Replace on that row. In the API, POST /personas/import and /personas/import/preview take an optional replace list of keys to rewrite, a plan entry's outcome can be skip, and the result counts skipped. A caller that relied on an import overwriting a matching character now has to name it in replace.
• A news story read from a publisher's page no longer carries the publisher's own pitches into a bulletin: a broadcaster's membership ask, a "Read more:" link to another story, a writer plugging their own book or newsletter, and an editor's note set entirely in italics are all left out, the way a sponsor's message already was.
