The first board column is the Inbox on every track. Research and Explore's "To-Do" becomes Inbox (the same word the creation dialogs and parked cards already used), and Build's board gains one too, ahead of Analysis. One column means captured, nothing running yet: a card sits there while it has no worker, and leaving it is what starts the card.
Added
Deferred start for Build. "Start new issue" now offers Start immediately (checked), matching research and explore. Unchecked parks the card in the Inbox with no worker; the card offers Start, and dragging it into a phase starts it through the same shared spawn as preset restarts. Dragging a card that already has a worker into the Inbox is refused by the move policy with a named exit, so a running worker is never orphaned.
Fixed
Build state now reads identically on the board and in the open card. Both surfaces share the same ordered pills: board location, lifecycle state, worker state, and workflow type. The Kanban no longer substitutes a stage for status or prefixes the pills with a redundant “Status” label.
Audit and recovery evidence fail closed. Build completion now records the host-verified Git root and exact HEAD in audit.md; copied or stale receipts are refused. A recovered diff is also refused if its path no longer resolves to the Git root the person attached.
