The wwstage checker's asserttyped pass currently only WARNS on nil-typed nodes (a check-bail-discipline regression). Before re-arming it to a bail, this probe pins the warn set so the re-arm is verifiable — the live ww-driver suite is blind to it (the stdlib _run tests use the cstage ww driver, no asserttyped; 990 feeds only -t/-a). 901 runs the ww-stage checker (wwdump_ww -c) over the gap-bearing combined.ww fixtures and asserts the asserttyped warn count per fixture against a manifest: checked 0 (closed-root sentinel), smoke 3 (fn-ptr field call), utf8 8 (abort intrinsic), fnmatch 2 + random 16 (module-leaf==type/fn collision). Each subsequent stamping fold drives a count to 0 and edits its manifest line; the bail is safe to arm when all reach 0. A new nil-gap or a regressed class fails loud (mutation-tested both directions). Test-infra only — no compiler change.
