ckVision 0.1.19

ckVision 0.1.19 delivers the Progress Lab task display variants and the Mac client SDK bundle.

The attached ckvision-client-0.1.19-6b865375.tar.gz contains the installable macOS ARM64 CMake package, example applications, source documentation, and 225 generated figures. It was built from the public source snapshot 6b865375 and verified independently of the internal development tree. Archive SHA-256: 8695a3d208fd3d09716966a13acc258caca3e7cafea4d4465bbb4007711e13f8.

Verification: clean warning-free Release builds and full CTest suites on macOS ARM64 (233/233), Linux ARM64 (233/233), and Windows ARM64 (227/227); Linux ASan/UBSan with all 11 fuzz corpora (244/244); Linux TSan (232/232); benchmark smoke; modern Windows ConPTY (34/34). The filtered public snapshot separately passed a clean Release build, 227 non-PTY and four PTY tests, and a strict documentation build. All seven GitHub CI jobs passed on the public commit.

The owner approved this release and explicitly waived the interactive five-app walkthrough. The owner also directed that the idle-Mac p99 and theme-switch baseline be skipped for this release. Those measurements remain open in the roadmap; this release does not claim that they passed.
