Add Python 3.15 RC2 preview legs on Windows, macOS, and Linux x64/ARM64 so the existing PR validation flow can expose product and packaging blockers before GA. Skip Arrow-only tests on 3.15 until PyArrow publishes compatible wheels. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

### Work Item / Issue Reference > #817 ------------------------------------------------------------------- ### Summary Extends the governed build and release pipeline to produce Python 3.15 wheels without changing Conda packaging. - Adds Python 3.15 x64 and ARM64 Windows stages. - Adds a Python 3.15 macOS universal2 stage. - Adds `cp315` to all manylinux and musllinux x64/ARM64 build loops. - Extends release-lock compatibility validation to Python 3.15, allowing source builds where upstream wheels are unavailable. - Raises the consolidated wheel completeness gate from 34 to 41 wheels. ### Validation - YAML and whitespace validation passed. - Hosted universal-lock generation completed successfully for Linux, macOS, Windows, and ODBC. - The full build-release pipeline is the validation for native wheel production, tests, signing, and artifact completeness. ### Scope This PR covers PyPI wheel production only. Conda Python 3.15 packaging is intentionally excluded. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

A consistent change requires more than 20% median paired movement, at least 1 ms between the median runtimes, and at least 80% of pairs exceeding the relative threshold in the same direction.

🔵 Needs a closer look
Cross-platform packaging, channel resolution, and native ARM64 behavior still require approved-agent validation.

What changed in this PR
Adds ordinary CPython 3.15 to the Conda packaging matrix while preserving existing versions and published-wheel smoke validation.
Changes:
- Expands Conda builds and release validation to 34 variants.
- Handles Python 3.15’s Windows site-packages layout and builder/channel requirements.
- Makes the Linux smoke test use the current published binding and exact dependencies.

Work Item / Issue Reference
Summary
Add ordinary CPython 3.15 to the existing combined binding/ODBC/RS Conda package without removing older supported versions.
lib/python/site-packageson 3.15, retainingLib/site-packageson older Python.<26constraint.microsoft, thenconda-forge, for the win-arm64 3.15 build and verification dependencies. Preserve the exact older-version channel policies and the 3.12 ARM64 ABI workaround.Source RS/ODBC versions, optional dependencies, OS floors and publisher tools are unchanged.
User-directed PR smoke follow-up: keep current-checkout source tests blocking, but obtain the real Linux CPython 3.11 smoke inputs directly from PyPI using
fetch-wheels --published-smoke. Select PyPI's current published binding and its exact ODBC/RS dependencies, rather than unpublished source versions or independently mixing latest components. No smoke versions, filenames or SHA256 values are hardcoded. Downloads still require PyPI-provided hashes and actual METADATA/WHEEL/RECORD/dependency checks. Missing or mismatched inputs fail; no skip, older-release fallback or release-policy relaxation. The workflow supports both embedded-core and separate-RS published bindings without substituting source RS pins. This published packaging control does not qualify current-source RS or CPython 3.15. Production/default source-bound selection and trigger scoping are unchanged. The hardcoded digest literals reported by DevSkim have been removed, not suppressed.Builds on merged #817 and now targets
main.Validation
Result: 1,388 passed on the initial Conda support commit. These are source-only packaging/tooling tests, not native driver or SQL integration tests.
Result: 1,073 passed on the PyPI-selection follow-up, covering explicit published/source selection, unavailable or invalid published dependencies, target restriction, embedded/separate RS and existing digest/dependency/provenance/trigger controls. Live
read_published_versions()selected the current PyPI binding and its exact ODBC requirement successfully. Earlier local wheel-download attempts hit TLS handshake errors on Windows and a bounded Linux container; no TLS bypass was used. The normal post-push hostedconda-auditrun validates actual wheel downloads and the build/audit for this revision.Result: all passed. Normal commit and push hooks also passed.
Earlier bounded local experiments solved the full ordinary-3.15 runtime dependency closure on all six subdirs. Synthetic packaging with actual Conda interpreters and conda-build 26.9.1 passed for win-64 3.10/3.15 and cross-built win-arm64 3.15, including ABI, PE and installed-component checks.
Not end-to-end qualification: this host's
NoDefaultCurrentDirectoryInExePathsetting blocks conda-build's normal bare batch-file launch, including the productionbuild_packagesinvocation. The synthetic packaging results used an explicit-path generated-batch launch followed byconda-build --post, without changing host policy or installed libraries. They do not establish normal pipeline success or native ARM64 execution. Approved-agent execution, real candidate wheels, native platform/SQL/TLS/authentication/bulk-copy and optional-feature qualification remain pending. No ADO pipeline was queued and nothing was published to Anaconda.
