crit-2's failure mode discards every frame outside the signal site —
including the covering test's own assert — which is why the shipped test
"signal returns handler value to call site" passed vacuously pre-fix. A
plain assert pin would inherit that vacuity on regression.
Add suite gate-crit2-signal-return-kont with a side-effect sentinel: test 1
runs the core.md repros ((list "outer" (handler-bind ... (+ 1
(signal-condition 5))) "end") -> ("outer" 43 "end"); raise-continuable ->
143) then set!s a top-level flag; test 2 independently asserts the flag, so
a dropped continuation fails loudly even though test 1 would "pass". Third
test pins the shipped-test expression (51). 267 passed / 0 failed under
OCaml run_tests.

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).

Three dc7aa709 fixes shipped without pinning tests:
- K09: R7RS longhand (unquote-splicing X) now splices (was silent zero-splice)
- K11: guard re-raise sentinel gensym'd — a user value shaped like
(list '__guard-reraise__ X) is data, not a forged re-raise
- K39: (do ((fn (x) x) 5) 99) -> 99, not a misparsed Scheme do-loop
Add suites gate-K09-longhand-unquote-splicing, gate-K11-guard-reraise-forgeable,
gate-K39-do-iife-head to spec/tests/test-gate-pins.sx with exact reprs from
plans/sx-review/core.md. 261 passed / 0 failed under OCaml run_tests.
Test-only: no semantics edits, no push.

contains? did not support dict key membership in the real runtime —
(contains? {:a 1} :a) threw "contains?: 2 args", contradicting its own :doc.
The fix landed (primitives.sx + sx_primitives.ml) but had no pinning test.
Add suite gate-K20-contains-dict to spec/tests/test-gate-pins.sx (4 tests,
repro from plans/sx-review/core.md): present key true, missing key false,
list membership + string substring unchanged. 8/8 green under OCaml run_tests.

The dc7aa709 quick-wins batch fixed `expt`'s silent 63-bit int wrap (now
promotes to float like +/*) but shipped no pinning test — a regression would
pass silently. Add spec/tests/test-gate-pins.sx suite gate-K18-expt-overflow
(4 tests, minimal reprs from plans/sx-review/core.md): small exponents exact,
2^62 and 2^100 do not wrap, 2^100 is a float. 4/4 green under OCaml run_tests.
Also bootstraps plans/agent-briefings/sx-gate-loop.md (the loop's own briefing,
absent until now) with the W14 checklist derived from PLAN.md §W14.
Test-only: no semantics edits, no push.
