attempt-6: address Adi's two in-scope findings (#3 deferred to E6). #1 E4-own-author-type-arg (silent-wrong): the bare-TYPE gate returned `.proceed` for the querying source's OWN author, so the non-leaf sites (reflection / type-arg / array-literal / type-value / match arm) dropped it and re-resolved a same-name flat import via global `findByName`. headTypeGate now resolves the own author to ITS per-source TypeId (mirroring selectNominalLeaf's own-wins, 0754); the type-as-value and type-match sites, which only consumed the poison bit and re-resolved globally, now route through the gate and use the `.resolved` author. size_of(Widget) with an own + imported Widget now yields main's own size, not the import's. #2 E4-type-fn-head-ambiguity (silent-wrong): headFnLeak only checked isNameVisible, so two flat same-name type-returning functions both reported "visible" and one was silently instantiated. It now diagnoses >=2 distinct direct flat type-fn authors (no own author) as ambiguous before the isNameVisible short-circuit, consistent with the parameterized struct / protocol heads and the leaf (0755/0767). Own / single / diamond-collapse type-fn heads still resolve. Regressions: 0768 (own-wins at every non-leaf bare-type site, fail-before reflection=16 -> pass-after 8) and 0769 (two flat Make type-fns -> ambiguity diagnostic exit 1). README: own-wins + type-fn-head ambiguity at every bare-type site.
