v0.1.15
Fixed
- "solver install failed (1)" on macOS — setup could pick up the system Python 3.9 (shipped with Apple's Command Line Tools) when no newer Python was installed. The separation engine installed fine on 3.9, but the solver component (yt-dlp-ejs) requires Python 3.10+, so setup failed at the last step. StemKit now requires Python 3.10–3.12 and falls back to its bundled Python 3.11 otherwise — affected users are repaired automatically on the next setup run.
- Python selection now prefers the newest compatible interpreter on the machine (3.12 > 3.11 > 3.10) instead of the first one found.
- Solver install errors are no longer silent — the actual pip error is now shown in the setup log and included in the failure message, so reports like "(1)" come with a reason.
