Brief lives in project memory; pushed wakes share the sweep pipeline; case-ledger dedup.
Board stays the lead's substrate; outward actions ride the normal approval settings.
swe-lead (minimal tools, coordination verbs) + swe/design/test workers with the shared worker contract; workers never surface in the picker — they're staffed, not started.
Staffing card rides the approval slot; workers nest under the lead's ONE expandable RECENT entry in both sidebar layouts.
Per-session coworker+folder chips replace the sidebar split-button picker; code family gets a send-time folder dialog with git-ready temp dirs and Save as project.
Builtins ship enabled; user-facing noun is Coworker; personas flag now defaults on.
