+- 2026-05-01: Phase 22 Lua done — math/string/table stdlib tables + lua-force in lib/lua/runtime.sx. 185/185 tests (28 new). ec3512d6.
 - 2026-05-01: Phase 22 CL done — runtime.sx (103 forms): type preds, arithmetic, chars, format, gensym, values, sets, radix, list utils. cl-empty? guards nil/() split. 68/68 tests. 1ad8e74a.
 - 2026-05-01: Phase 22 step 1 — SX primitive baseline added to CL/APL/Ruby/Tcl plans. f43659ce.
 - 2026-05-01: Phase 21 complete — format (~a ~s ~d ~x ~o ~b ~f ~% ~& ~~ ~t) as pure SX in spec/stdlib.sx. Fixed lib/r7rs.sx number->string to support optional radix; added format-decimal OCaml primitive. 28/28 tests on both JS and OCaml. 4d7b3e29.
