PlateRevision Heirloom

This vault exists to keep each drawing plate’s change story nested and knowable, so anyone can see what moved on a sheet and why before the next issue ships. It turns foggy revision memory into a living lineage you can trust when production asks hard questions. Issue, mark-up, revise, check, release, supersede, and archive episodes stack like heirloom chapters under every plate. Fork a branch when fitment splits, stamp uncertain against confirmed marks, wire transparent supersede links, and keep shop sets apart from client packs without losing the chain that got you there. Gap review hunts sheets missing a clean release or closing archive node; density strips and split-compare expose how two lineages breathe side by side. Title-block checklists ride inside episodes as deliverables—so the story of the plate stays as sharp as the steel it describes.
