Mine the remaining integration 'ported Clojure' batteries into the spec layer
and delete them (clojure-atom/control/for/logic/macros, core, logic). A broad
function-coverage diff confirmed they exercised no clojure.core fn the spec
lacked; their distinctive value was the truthiness/boolean contract, now
captured in a dedicated spec.
New/expanded spec coverage:
- spec/truthiness-spec: only nil/false are falsy (0, "", [], {}, #{} are truthy);
not / and / or return-value & short-circuit semantics; if-not/when-not/boolean
- assert (exceptions-spec), get-validator (state-spec)
Layout now: spec 23 files / 732 cases; integration trimmed to 10 genuine
cross-cutting batteries (conformance, SCI bootstrap/runtime, jank, compile-mode,
api, namespace, bootstrap, features, systematic-coverage). conformance 218/218,
jpm test green.
