K49: area/base/embed/param/track were in VOID_ELEMENTS but missing from
HTML_TAGS — render fell through to "Undefined symbol: base". dc7aa709 fixed
spec/render.sx; add suite gate-K49-void-elements-renderable (3 tests): the
spec registry contains all five, and render-to-html renders each as a
self-closing void. 264 passed / 0 failed under OCaml run_tests.
DISCOVERY (recorded in the briefing's Blocked section): the generated
hosts/ocaml/lib/sx_render.ml was never regenerated after the spec fix — its
stale html_tags_list still lacks the five tags, so the runner's native
render-html path STILL errors. Fix is a bootstrap_render.py regen (hosts
lane, out of scope for this test-only loop). Live evidence for F13
(regen-diff CI gate). Pin covers the spec side only for now.
Also corrects the checklist label: K49 = void elements; the depth/cycle
guard is K16 (OPEN, W8).
Test-only: no semantics edits, no push.
