v0.12.27: @newsroom.newsletter: Issue 6, The reader's own newsroom

Issue 6 of the SGit Newsroom newsletter, the first written in this repository (admin/content/newsletter/006-2026-10-13.md) and published by publish.py. Eight articles from 11 to 13 October on the reader's vault: the passkey design and the test that made the door a door per path, the night the vault went live, what it did next that nobody planned (a second Chrome profile is a second device; sixteen changes stranded in one browser, and a lane any browser can write to), and what a reader does with it (the site as an inbox, ways into one article, a reading list in a link, and five themes). One collage of six pictures, eight quotes checked word for word against their articles by the build, three figures, and a 1920x1080 cover for LinkedIn.

Also in this release: issue 3 links its LinkedIn version, posted on 13 October, on its page and on its card in the list of issues. Issue 3's source is sgit.ai's, which this site does not edit, so the link is added on import by two recorded text rules in admin/build/newsroom-text.json, issue-3-linkedin and issue-3-linkedin-card, in the same words and markup as issues 1 and 2. The engineering map now counts ten text rules and the import's items up to 15.
