build_one_sep (both stages + ww/main.combined.ww regen): discover_deps (transitive directory-package set, dotted-path identity), tri-color reverse-topo (cycle bails; loud reject is commit 4), the transitive producer loop (one w6c -c -I pass per package, dep-first, each both consumer and producer of its .wwi), and a flat w6l of the .o set. combined.ww stays the DEFAULT live path; --sep is additive. Every dep is tagged by its full dotted import path on prepend (//ww:module <path>), so the definer's qualified symbol (#53) == the consumer's qualified reference (#40) and the sep .o set links. The prepend is the TRANSITIVE closure (lead-ratified, superseding rob-c3-spec §1.3 direct-deps): a dep's interface can name a transitive dep's type (os exposes time.instant), so the consuming unit needs the whole closure for resolution — direct-deps-only does not type-check. Consistent with the current flat-unit transitive-namespace model (the visibility tighten is #45, post-M4). Gate 989_sepbuild_run drives ww + ww_ww --sep on the real chain root->os->{rt,time}: build+run (exit 7) + cs==ww per-pkg .s/.wwi/.unit + final binary + transitive-topo discovery + keystone bodies==.wwi (os,root) through the real driver. Cold scratch; -o-redirected.
