+- 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.
 - 2026-04-26: Phase 7 complete — bitwise-and/or/xor/not + arithmetic-shift + bit-count + integer-length. OCaml: land/lor/lxor/lnot/lsl/asr + Kernighan popcount + lsr loop for integer-length. JS: bitwise ops + Hamming weight + Math.clz32. 26 tests, 158 assertions, all pass. a8a79dc9.
 - 2026-04-26: Phase 6 complete — JS+Tests+Commit all ticked. JS needed no changes (spec-level forms). 40/40 ADT tests pass JS. 2032/2500 JS total (+67 vs phase-4). Phase 6 fully landed: 6c872107+0dc7e159+5d1913e7. Phase 7 (bitwise) next.
