cuda.bindings: import maintained CUDA 12.9 source root
Narrative review layer 1 of 6. Bring the source import from Keith PR #2675 into a separate cuda_bindings_12 package root and synchronize it through released v12.9.9. Preserve the PR-specific coredump lifetime overlay and the focused maintenance-test adjustments, including loading the shared pytest safeguards. Repository-wide hygiene recognizes the second source root, including generated-file seals, SPDX validation, labeling, lint, and preview cleanup. Review focus: the source import and maintenance provenance, plus the small hosting changes outside cuda_bindings_12. This is a narrative decomposition of PR head 59ff7bd; intermediate layers need not build independently.

and conversions to other media types.
36+
37+
"Work" shall mean the work of authorship, whether in Source or
38+
Object form, made available under the License, as indicated by a

copyright notice that is included in or attached to the work
40+
(an example is provided in the Appendix below).
41+
42+
"Derivative Works" shall mean any work, whether in Source or Object
43+
form, that is based on (or derived from) the Work and for which the
44+
editorial revisions, annotations, elaborations, or other modifications
45+
represent, as a whole, an original work of authorship. For the purposes
46+
of this License, Derivative Works shall not include works that remain
47+
separable from, or merely link (or bind by name) to the interfaces of,
48+
the Work and Derivative Works thereof.
49+
50+
"Contribution" shall mean any work of authorship, including
51+
the original version of the Work and any modifications or additions
52+
to that Work or Derivative Works thereof, that is intentionally
53+
submitted to Licensor for inclusion in the Work by the copyright owner

the copyright owner. For the purposes of this definition, "submitted"
56+
means any form of electronic, verbal, or written communication sent

to the Licensor or its representatives, including but not limited to
58+
communication on electronic mailing lists, source code control systems,

69+
this License, each Contributor hereby grants to You a perpetual,
70+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
71+
copyright license to reproduce, prepare Derivative Works of,
72+
publicly display, publicly perform, sublicense, and distribute the
73+
Work and such Derivative Works in Source or Object form.
74+
75+
3. Grant of Patent License. Subject to the terms and conditions of

(except as stated in this section) patent license to make, have made,
79+
use, offer to sell, sell, import, and otherwise transfer the Work,

where such license applies only to those patent claims licensable
81+
by such Contributor that are necessarily infringed by their
82+
Contribution(s) alone or by combination of their Contribution(s)
83+
with the Work to which such Contribution(s) was submitted. If You
84+
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+
96+
(a) You must give any other recipients of the Work or
97+
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.
