_prepare_existing_venv, validate project_dir and resolve the uv executable
before invoking stale-environment cleanup. Preserve the existing early-return
behavior, but ensure invalid project paths or unavailable uv do not delete a
usable environment; update affected tests, including
test_matching_marker_keeps_existing_pinned_venv, to patch resolve_uv_bin as
needed.

49-53: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy liftInclude the interpreter request in environment identity.
BaseInstaller.all_items()deduplicates installables withset. These lines make PythonExecutable instances with the same repository and commit equal even when they request different Python versions. One request is discarded, and the sharedvenv_namepermits only one resulting interpreter.Include the effective interpreter request in PythonExecutable equality, hashing, and environment naming, or reject conflicting requests before deduplication. Add coverage for two entries that use the same repository commit with different Python versions.

- Line 135: Update the cleanup around shutil.rmtree in the Python executable
installation flow to verify project_dir.is_dir() before deleting the existing
environment, preserving the usable environment when project_subpath is missing
and the pinned marker is stale. Add a regression test covering a stale
environment with a missing project_subpath and confirm _create_venv still
returns an InstallStatusResult.
- Line 163: Update the explicit Python version handling in the relevant property
or method so whitespace-only values are treated as unset before returning or
passing the version onward. Preserve the fallback to .python-version or
sys.executable for empty-after-stripping values, while continuing to use
non-empty explicit versions.

Tip For best results, initiate chat on the files or code changes.
Full support would require separate virtual-environment identity and shared-clone serialization. Deferring this work is reasonable until a concrete workload requires it. I am replying to the latest comment only and do not have the full earlier thread context. 🐇 ✏️ Learnings added

Summary
Certain git repo installable needs specific python versions. For example MBridge's NeMo-Run needs 3.11.9 and doesn't work with 3.14 (which is target for this repo).
