Why: Delivery requires writing planning progress back after U7
landed; the proposal still claimed U1+U2 start / NOT_RUN.
Evidence: SELF doc edit against archived U7 cards and release
checklist A1-A7/B1 facts.
Impact: Readers see code-done vs capacity-window-pending; adds
HTTP multi-instance vs Manager-test lesson.
