The bare-`main` carve-out (which keeps the link entry's main unmangled) keyed on `leaf == "main" && imported == 0`. Under the combined path a dependency's body folds in with imported==1, so only the root's main stayed bare. Under separate compilation each package is its own unit and a dependency's body carries a path-mangling module-reset but imported==0 (#57) — so an imported `fn main` matched the carve-out, emitted a bare `TEXT main`, and collided with the root entry (`w6l: duplicate symbol main`). The combined path was unaffected, so this only surfaced under sep. Gate the carve-out with sep_isdep = (wwiout != NULL): the producer emits a .wwi output only for dependency units, never for the root/link-entry unit (root stripped, #69), symmetric on both stages. Only the root unit's main now stays bare; an imported package's main mangles on its import path (e.g. aa.bb.main). Both stages. Gate: test/wcc/989_depmain_sep.c (table-driven, dotted + single-component shapes, both stages; asserts the mangled dep main + a single bare root main + cs==ww byte-id; combined path stays neutral).
