New 30-macros tier (registered after 20-coll) for user-facing macros expressed as defmacro + syntax-quote instead of hand-built Janet form-transformers. Validated end to end: overlay-defined macros expand in interpret, compile AND self-host modes (conformance 228/228 x3). Moved comment and if-not; removed their Janet core-X fns + core-macro-names entries. Note: Jolt defmacro is single-arity, so multi-arglist macros become one arglist with & rest / destructuring (if-not uses [test then & [else]]). Macros used by the compiler or earlier tiers (and/or/when/cond/case/cond->/->/declare/ doseq/when-let) stay in Janet until a load-order story exists for them. full suite green, clojure-test-suite 3930.
