Per the tier+stage split (USER-approved): the routine wwstage-behavior run is redundant -- T2 byte-id (cstage.s vs wwstage.s, strictly more sensitive) plus T1's cstage run together cover both stages. Drop the wwstage path from runww; cstage==wwstage convergence moves to a separate pre-push byte-id tool (T2). Update the test-run target comment to match.
