cuda.bindings: import and adapt the maintained CUDA 12.9 root
Review-only narrative layer 1 of 6 for #2737. Preserve Keith Kraus's source import from PR #2675, synchronized through v12.9.9 (89713a7:cuda_bindings), together with the maintenance root's build hooks, focused runtime/test fixes, shared pytest bootstrap, and repository hosting safeguards. This includes intentional adaptations and the coredump lifetime overlay; it is not a pristine upstream copy. Packaging selectors and Pixi integration follow in layers 2 and 4. Review the three conftest copies and the build-hook consistency checker together. Implementation source: 6c3de41 Review baseline: ab9e20f Read these commits in order. Shared files are assigned as complete files to one layer, so intermediate commits need not build or pass CI. Only the final Git tree matches the implementation. This branch is a reading aid, not an alternate merge or release path. Validation belongs to the implementation source above.

## Synchronized code blocks
17+
18+
Use matching `BEGIN SYNCED <group>` and `END SYNCED <group>` comments for
19+
deliberately duplicated snippets whose contents must remain byte-for-byte
20+
identical. The group name identifies all copies; the boundaries define the
21+
shared snippet, not the surrounding file.
22+
23+
- Before editing a marked block, search from the repository root for its exact
24+
`BEGIN SYNCED <group>` marker, for example with `rg -n -F`. Read every copy
25+
and update them together, including copies outside the current package.
26+
- Compare the complete marked blocks after editing. Also check required
27+
imports and surrounding assumptions, such as relative directory depth,
28+
which may live outside the markers.
29+
- During review, identify groups touched by the diff and compare every copy,
30+
including files absent from the diff. Use the base revision too when markers
31+
were removed or renamed. Report drift, missing boundaries, and newly copied
32+
snippets that omit the markers as review findings.
33+
- Preserve both markers when copying a snippet. If a copy must diverge,
34+
explain why and explicitly revise the group membership; do not remove or
35+
rename a marker merely to conceal drift.
36+
- In the work or review summary, name the groups and files compared, or state
37+
why verification could not be completed.

# CUDA 12 maintenance bindings
2+
3+
This root maintains the CUDA 12.9 release line. Follow the repository-wide
4+
instructions and [maintenance guide](MAINTENANCE.md).
5+
6+
- Preserve the CUDA 12 generated source, build-time header parser, `.in`
7+
templates, legacy APIs, and namespace redirector. The CUDA 13 source layout
8+
and runtime extension list are different and must not replace these.
9+
- Do not hand-edit generated bindings. Change cybind and regenerate against
10+
the intended CUDA 12.9 inputs, recording provenance as described in
11+
`../ci/README.md`.
12+
- Source builds require CUDA 12.9 headers. `build_hooks.py` checks the first
13+
`cuda.h` found through `CUDA_HOME` or `CUDA_PATH` before generating files.
14+
Split toolkit installations remain supported through the existing path list.
15+
- The shared toolchain and Cython cache helper block must remain identical
16+
to `cuda_bindings/build_hooks.py` and `cuda_core/build_hooks.py`.
17+
`toolshed/check_build_hooks_sync.py` checks all three copies.
18+
- Assess handwritten fixes and build changes for both supported roots.
19+
Preserve intentional differences in generated APIs and packaging.
20+
- Use the package's `[test]` dependencies for Python tests. Build Cython tests
21+
with `tests/cython/build_tests.sh` or `build_tests.bat` before running them.

institute patent litigation against any entity (including a
85+
cross-claim or counterclaim in a lawsuit) alleging that the Work
86+
or a Contribution incorporated within the Work constitutes direct
87+
or contributory patent infringement, then any patent licenses
88+
granted to You under this License for that Work shall terminate
89+
as of the date such litigation is filed.
90+
91+
4. Redistribution. You may reproduce and distribute copies of the
92+
Work or Derivative Works thereof in any medium, with or without
93+
modifications, and in Source or Object form, provided that You
94+
meet the following conditions:
95+

Derivative Works a copy of this License; and
98+
99+
(b) You must cause any modified files to carry prominent notices
100+
stating that You changed the files; and
101+
102+
(c) You must retain, in the Source form of any Derivative Works
103+
that You distribute, all copyright, patent, trademark, and
104+
attribution notices from the Source form of the Work,
105+
excluding those notices that do not pertain to any part of
106+
the Derivative Works; and
107+
108+
(d) If the Work includes a "NOTICE" text file as part of its
109+
distribution, then any Derivative Works that You distribute must
110+
include a readable copy of the attribution notices contained
111+
within such NOTICE file, excluding those notices that do not
112+
pertain to any part of the Derivative Works, in at least one
113+
of the following places: within a NOTICE text file distributed
114+
as part of the Derivative Works; within the Source form or
115+
documentation, if provided along with the Derivative Works; or,
116+
within a display generated by the Derivative Works, if and
117+
wherever such third-party notices normally appear. The contents
118+
of the NOTICE file are for informational purposes only and
119+
do not modify the License. You may add Your own attribution
120+
notices within Derivative Works that You distribute, alongside
121+
or as an addendum to the NOTICE text from the Work, provided
122+
that such additional attribution notices cannot be construed
123+
as modifying the License.
124+
125+
You may add Your own copyright statement to Your modifications and
126+
may provide additional or different license terms and conditions
127+
for use, reproduction, or distribution of Your modifications, or
128+
for any such Derivative Works as a whole, provided Your use,
129+
reproduction, and distribution of the Work otherwise complies with
130+
the conditions stated in this License.
131+
132+
5. Submission of Contributions. Unless You explicitly state otherwise,
133+
any Contribution intentionally submitted for inclusion in the Work
134+
by You to the Licensor shall be under the terms and conditions of
135+
this License, without any additional terms or conditions.
136+
Notwithstanding the above, nothing herein shall supersede or modify
137+
the terms of any separate license agreement you may have executed
138+
with Licensor regarding such Contributions.
139+
140+
6. Trademarks. This License does not grant permission to use the trade
141+
names, trademarks, service marks, or product names of the Licensor,
142+
except as required for reasonable and customary use in describing the
143+
origin of the Work and reproducing the content of the NOTICE file.
144+
145+
7. Disclaimer of Warranty. Unless required by applicable law or
146+
agreed to in writing, Licensor provides the Work (and each
147+
Contributor provides its Contributions) on an "AS IS" BASIS,
148+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
149+
implied, including, without limitation, any warranties or conditions
150+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
151+
PARTICULAR PURPOSE. You are solely responsible for determining the
152+
appropriateness of using or redistributing the Work and assume any
153+
risks associated with Your exercise of permissions under this License.
154+
155+
8. Limitation of Liability. In no event and under no legal theory,
156+
whether in tort (including negligence), contract, or otherwise,
157+
unless required by applicable law (such as deliberate and grossly
158+
negligent acts) or agreed to in writing, shall any Contributor be
159+
liable to You for damages, including any direct, indirect, special,
160+
incidental, or consequential damages of any character arising as a
161+
result of this License or out of the use or inability to use the
162+
Work (including but not limited to damages for loss of goodwill,
163+
work stoppage, computer failure or malfunction, or any and all
164+
other commercial damages or losses), even if such Contributor
165+
has been advised of the possibility of such damages.
166+
167+
9. Accepting Warranty or Additional Liability. While redistributing
168+
the Work or Derivative Works thereof, You may choose to offer,
169+
and charge a fee for, acceptance of support, warranty, indemnity,
170+
or other liability obligations and/or rights consistent with this
171+
License. However, in accepting such obligations, You may act only
172+
on Your own behalf and on Your sole responsibility, not on behalf
173+
of any other Contributor, and only if You agree to indemnify,
174+
defend, and hold each Contributor harmless for any liability
175+
incurred by, or claims asserted against, such Contributor by reason
176+
of your accepting any such warranty or additional liability.
