@romeokienzler the DCO is failing, make sure all your commits are signed off. Also you have conflicts on the locks and requirement files. |

The tests are failing because of your conflicts and the CI is not able to merge your changes with main. Make sure that you are rebased on the latest main. |
Add the gridfm-graphkit PowerFlow-reconstruction model package
(models/gridfm-pf-reconstruction) and pin gridfm-graphkit for the
ecosystem and candidate variants.
- ecosystem: gridfm-graphkit==0.9.0.3 (bare)
- candidate: gridfm-graphkit[vllm]==0.9.0.3 — its `vllm` extra targets
vllm>=0.29,<0.30, matching this variant's vllm==0.29.0. Not added to
product (vllm>=0.28,<0.29) until validated there.
- [tool.uv.extra-build-dependencies] torch-scatter=["torch"]: gridfm
(>=0.9) depends on torch-scatter, whose sdist imports torch at build
time without declaring it; inject torch so `uv lock` can build metadata.
- Regenerate uv.lock (gridfm 0.8.1->0.9.0.3, gridfm-datakit 1.0.5->1.1.0,
+torch-scatter 2.1.2) and requirements-{ecosystem,candidate,product}.txt.
Rebuilt on top of current origin/main (candidate already at vllm==0.29.0
+ terratorch[vllm]==1.2.13). Invariants: no vllm in ecosystem;
vllm==0.29.0 in candidate; gridfm absent from product. nexus validate
passes; all pre-commit hooks green.

@christian-pinto could you re-trigger the Tekton pipeline for this PR when you get a chance? Three contexts are showing a terminal
The other 8 checks are green (DCO, detect-secrets, vulnerability-scan, branch-protection, unit-tests under pr-code-checks). Locally For reference, this push rebased onto current |

The pipeline re-runs every time you push a new commit. Currently it is failing because of a mismatch with the lock file. Make sure you update the lock file. We even have an agent skill for that. Also, make sure you have the pre-commit hooks installed that will re-generate the requirement files if when you try to commit. Updated requirement files are also to be committed here is the log for the failing unit test |
