Split Roadmap into Changelog and Backlog pages 'Roadmap' implied a forward-looking plan, but the page was mostly a record of decisions already made -- split into pages that say that directly: - Changelog: what was built, when, and why (formerly 'Done' and 'Bugs found and fixed along the way'). - Backlog: what's deliberately not built yet and why, plus scope boundaries (formerly 'Deferred on purpose', 'Explicitly out of scope', and 'Foundation review'). Dropped 'Plausibly next' outright -- its only entry was already marked RESOLVED and duplicated in the Changelog's own 'Cairo removed entirely' entry. Roadmap.md kept as a short pointer to the two new pages for anyone with an old link/bookmark, rather than deleted outright. Home.md updated to link to both new pages. Content verified preserved byte-for-byte (diffed the extracted section bodies against the new files) except for the new intros and one now-cross-page Done-section reference, fixed to point at the Changelog explicitly.
