//ww:error "duplicate fn main"
// Pilot for #7a: two `fn main` definitions must be LOUD-rejected by BOTH
// stages. The substring is the shared diagnostic body (no file:line prefix,
// which differs cstage vs wwstage) — the #20 non-vacuity anchor and the
// dual-stage (w6c AND w6c_ww) reject-coverage proof.
