Removing the public extend_known_versions method also conflicts with the stated backward-compatibility requirement [ Full details: Out of Scope Changes checkExplanation The PR adds broad ExternalCommands environment-filtering behavior and removes a public method. These changes are not clearly required for version-specific prebuilt wheel configuration and are not connected to VersionSpecificSettings.

- Around line 130-131: Update the requirement resolution flow around
_extract_pinned_version and _phase_start so unpinned range requirements resolve
each candidate using that version’s pre_built setting and matching distribution
URL, rather than choosing the variant default before resolution. Ensure source
preparation receives an sdist URL and _bg_prepare_prebuilt receives a wheel URL
even when a candidate overrides the default mode, and add regressions covering
both override directions.
- Around line 33-34: Update _extract_pinned_version so an equality specifier
whose version ends with .* returns None instead of being passed to Version();
retain the existing Version conversion for exact == versions and the surrounding
BootstrapRequirementResolver.resolve behavior.

- Around line 317-321: Add version-specific env and annotations fields to the

merge paths to apply these values over variant defaults while preserving
inheritance when they are unset.
- Around line 373-382: Add a concise docstring to the public validator method
before_none_versions stating that it converts a None versions value into an

overrides documentation near the shown package-settings section, and by the

version-specific wheel URLs are re-resolved for every applicable resolved
requirement, not only when wi.pbi_pre_built differs from pbi.pre_built, while
preserving the original URL fallback when resolution fails. After selecting
wi.source_url, update the dependency graph’s download_url edge to match the
final URL before later parallel builds consume it. Add regression coverage for
an unpinned prebuilt requirement whose resolved version supplies a different
wheel_server_url while retaining the same pre_built value.

This can raise an unhandled ExceptionGroup from wheels.resolve_prebuilt_wheel (which propagates from resolve_all_prebuilt_wheels at wheels.py:548) if no matching wheel is found on the version
-specific server. The source branch correctly returns None when no results are found (line 46-47), but the prebuilt branch has no exception handling. The caller at line 142-147 expects either a URL or None and logs a warning on None — an uncaught exception would instead crash the bootstrap run.
Can we wrap the prebuilt resolution in a try/except block and return None on failure, matching the source branch's behavior?

Wrapped resolve_prebuilt_wheel in a try/except ExceptionGroup block that returns None, matching the source branch's behavior.
The caller already handles None by falling back to the original URL with a warning.

This function is the most important part of PR and has no test coverage.
Can we add tests for
(1) re-resolution when version-specific pre_built=True overrides variant default pre_built=False (prebuilt path),
(2) re-resolution when version-specific pre_built=False overrides variant default pr e_built=True (source path),
(3) re-resolution when only wheel_server_url differs,
(4) failure handling when re-resolution returns None (falls back to original URL with warning),
(5) no re-resolution when version-specific settings match variant defaults.

Added 7 tests in TestReResolveUrl covering: prebuilt success, source success, ExceptionGroup failure, empty source results, wheel_server_url mismatch triggering re-resolution, no re-resolution when settings match, and fallback on failure.
