mcpp 2026.11.3.1 defaults both openkal targets to platform 0.23.3 and builds the Windows package launcher against os 0.2.9. The public version group is Linux 0.24.1, image 0.4.3, musl 0.27.3 and llvm-runtime 0.18.4 over openkal 0.23.0. All prerequisite source releases, mirrors and public index archives are verified. The Linux libraries and native runner carry the corrected read-only confinement policy and atomic ABI probe cache.

The std module receives the platform's compile flags and includes them in its cache identity. Package-format providers receive the selected compression. Runner cache collection selects valid versions and preserves native Windows paths. Object-only packages list every compile object as a default goal, including musl's 1,332 own C objects. The build-program preparation code moves to its own file with its function bodies preserved.

The manifest and compiled version both report 2026.11.3.1. The bootstrap pin remains on the existing installable compiler until the new release is mirrored, indexed and actually installable. English/Chinese usage examples, release notes and the design's current dependency table follow the final group. Snapshot generation is documented as asynchronous; historical warm-start observations are not presented as final resource measurements.

Validation:

• A fresh native self-build reports 2026.11.3.1 and both built-in rows select platform 0.23.3.
• Root and toolchain-model tests: 164 programs pass, zero fail.
• A fresh project with no platform override or old lock builds and runs an import-std image over the public 0.23.3 group.
• Final public-group E2E 01/942/951 pass, including both image architectures, std, pack modes, refusals and a workspace. Version, documentation and module wiring guards pass.
• Full PR CI, including actual legacy-ACP Windows probes, remains required at the final head. Platform PR 0.23.3: propagate the corrected Linux confinement graph mcpplibs/openkal-platform#16 must pass its complete four-host rerun with this compiler default before merge.

Part of #885 (T5). The compiler release, final released-engine producer checks, consumer releases, cleanroom installation and final resource measurements remain tracked there. Existing published tags and archives remain unchanged.
