How the story changed, release by release
Every section of this site is a projection of the evidence, and every projection is versioned. Across: each release of the site. Down: the front page's sections, each reader's briefing, and the story and evidence pages. A filled cell is a new version written in that release; a faint cell is a section that existed and did not change. A new fact for engineers moves the engineer's briefing and leaves the board's alone, and this table is where that shows.
Versions before v0.3.2 are reconstructed from each release's markdown twins and data files in git. The ledger itself is data/sections.json. What each release changed, in a sentence, is the release history; what changed for readers is what's new.
