SURFACE §1 super-simple example uses slack: '#releases → {{prev}}' — that shape needs a compiler pass that expands YAML helper verbs into effect steps consuming the same helper client as f.slack (from B). Lowers to kernel effect primitives; type-parity with the TS surface. Not-in-scope: new kernel primitives; provider-specific rich types.
