Checks & Lenses

Checks are standalone standard-library scripts returning exit 0 (done or clean), 1 (findings), or 2 (unable to run). They identify concrete file:line defects and do not decide whether to ship. Construction asks whether a thing was built correctly; conformance asks whether it matches an independently authored specification, including both missing and undeclared elements. Three lenses cover architecture, engineering review, and documentation coherence.
