OpenStudio 0.0.16

Optional AI runtime candidate for application 0.1.04. The application, model
weights and device-specific accelerator packages remain separate downloads.
The review in application PR #27
covers the range since the last published all-platform runtime
and the macOS preparation correction. The separate
Linux 0.0.14 hotfix
remains the selected Linux archive for this application candidate.

Highlights

Prepare portable Python 3.11.15 runtimes for Windows x64, macOS Apple Silicon
and Linux x64. The Windows base stays lightweight, with accelerator packages
installed through the existing on-device plans.
Qualify macOS preparation and the relocated archive in PR CI before creating
another component release. That smoke archive uses a test version and is
retained as a CI artifact; it is not published to the app's runtime catalog.

Replace the Windows Python 3.10.20 base, which the current managed installer
does not upgrade and the Audio Generation worker rejects. Python 3.11.15
satisfies the worker's interpreter contract.
Allow the macOS stem-separation dependency to build from source when upstream
has no Python 3.11 ARM wheel. The previous wheel-only requirement caused the
0.0.15 release attempt
to stop before macOS archive packaging. Its tag remains unchanged and no
runtime release was published from that failed attempt.
Require exact-version reviewed notes, matching source/tag identity, validated
archives and a final serialized publication check. Component publication
preserves the application's GitHub latest release and does not overwrite
existing assets. Cached macOS packages must pass current validation too.
Retain Linux archive relocation, model-cache and stem-checkpoint readiness
fixes. The Linux gfx1151 ROCm plan still requires device-specific qualification.

Windows Python 3.11.15 preparation and relocated archive validation passed in
the preceding attempt. The local base archive is approximately 47 MB; those
checks used 0.0.15 metadata and do not claim publication of version 0.0.16.
Publishing 0.0.16 requires successful preparation, packaging and relocated
archive validation on all three hosted platforms. These checks establish
interpreter, layout and capability-probe invariants; GPU inference and audio
quality need separate acceptance.

The downloadable macOS AI archive requires Apple Silicon and macOS 14 or
later because its bundled numerical-library wheels target that OS range.
This was already true of runtime 0.0.13; the base app's macOS 12 minimum
does not establish compatibility of the managed AI archive on macOS 12/13.
Physical GPU execution, clean on-device package/model installation and
generated-audio quality remain separate hardware qualification. Interpreter
compatibility alone does not establish those results.
macOS generic ACE Audio Generation is still constrained by the current
CUDA/ROCm hardware policy. This runtime does not enable Intel macOS AI
support, change model licenses or replace older installed worker scripts.
Existing managed Python 3.10 environments need repair or replacement;
publishing a new archive does not migrate an installed environment.

After successful component publication, select catalog version 0.0.16 and
ai-runtime-v0.0.16 for Windows/macOS. Keep ai-runtime-linux-v0.0.14 for
Linux. The application release later publishes the combined catalog; this
component release does not publish the application or submit it to Store.
Use AI Tools Setup to repair/install the optional runtime, preserving project
files and model caches. No project or runtime-metadata schema migration is
introduced by this component release.
