Card detail has one progress row, one home for files, and one reference. "What is happening" is now Workflow progress (where this card is), paired with the Workflow map (what each stage does) as a sibling section instead of nesting a reference inside card state. The section's redundant PROGRESS heading is gone, and the override coaching moved below the stage row, where it now appears only when an override is available.
No fact is printed twice. Each stage's document buttons are replaced by a count-only suffix (2 files), so a pill stays one click target and files keep one shape; the card's file count rides the section summary as the single route into Artifacts.
Removed
The now-unreachable stage-artifact highlight and group-ring plumbing, and the archived progress heading/hint that the disclosure summary already covered.
