# {{NAME}} The vault's catalogue. Maintained by `dj index --write` — entries are generated from each concept's frontmatter, so descriptions never drift. * [UI Refresh PRD]() - What the refresh covers, what it deliberately does not, and the acceptance bar per screen. * [Core Performance]() - Startup, sync and map performance — the numbers users feel before they feel anything else. * [UI Refresh]() - The visual pass — receipts, dark mode, and the booking flow brought up to the new system. * [Product]() - The product team's issues — every status in Linear's default lifecycle, every write through a declared form.
