+Subject: [PATCH] tests: allow functional tests to reuse a prebuilt wheel
+
+pytest_sessionstart always runs `uv build --wheel` to produce the wheel the
+venv factories install into their poetry/pdm/uv/pip environments. In a
+cibuildwheel job the interpreter's own wheel has already been built (and
+repaired) once; rebuilding it a second time from scratch to run the
+functional suite roughly doubles an already multi-minute native riscv64
+Rust compile for no functional benefit; the produced wheel is identical.
+
+DEPTRY_PREBUILT_WHEEL lets the caller point at that already-built wheel and
+skip the redundant rebuild; unset, behaviour is unchanged.
+
+Upstream-Status: Inappropriate [avoids a second from-scratch Rust compile inside a cibuildwheel test step; CI-infra only, nothing to fix in the project]

+Subject: [PATCH] tests: upgrade pip in each throwaway venv before installing
+ the wheel
+
+VirtualEnvironment.setup creates each poetry/pdm/uv/pip fixture venv with
+venv.EnvBuilder(with_pip=True), which provisions whatever pip ensurepip
+bundled for that Python build. On the manylinux_riscv64 cibuildwheel image
+that bundled pip predates riscv64 wheel-tag support, so `pip install
+--no-cache-dir <wheel>` against our own riscv64 wheel fails with "... is
+not a supported wheel on this platform" even though the outer test venv's
+own (newer) pip installs the identical wheel without complaint moments
+earlier.
