-## Review workflow
-1. Read the PR description, linked issues, and intended behavior.
-2. Inspect the diff before commenting.
-3. Identify affected MFEM components, examples, tests, build or docs changes, and downstream APIs.
-4. Analyze the code against the critical review pillars.
-5. Compare the change against nearby code and MFEM patterns; flag unmotivated deviations.
-6. Check whether tests and documentation were updated appropriately.
-7. Review CI results and suggest actions.
-8. Produce a structured review with prioritized findings.
-9. Always limit conclusions to available evidence.
-
-## MFEM-specific review checklist
- Component-aware scope: identify the touched subsystem (FEM, solvers, preconditioners, linear algebra, mesh, examples, miniapps, build, or docs) and assess its impact against the review pillars.
- Numerical and algorithmic behavior: assess issues in convergence, stability, tolerances, precision, iteration limits, and failure handling. If clear opportunities exist to improve the algorithmic approach, call them out with expected impact.
- API and user-facing impact: assess backward compatibility, user-visible behavior and default changes, migration impact, deprecations, and whether documentation clearly explains user-facing API changes.
- Data structure and memory semantics: assess ownership, lifetime, aliasing, container behavior, and device-host synchronization.
- Parallel and serial behavior: assess whether the change preserves equivalent semantics in serial and parallel modes where applicable; if logic is currently mode-specific, check whether extension to the other mode is straightforward (clear abstractions, no hard-wired assumptions), document constraints, and call out expected behavior differences explicitly.
- Backend and portability impact: assess likely cross-backend risks in CPU, CUDA, HIP, OCCA, RAJA, partial assembly, fallback paths, compiler compatibility, and platform assumptions.
- Build, dependency, and configuration impact: assess CMake or make changes, optional dependency behavior, and feature-flag interactions.
- Tests and docs alignment: check available regression or unit coverage evidence for changed behavior, and ensure docs are updated for new flags, APIs, options, or behavior changes.
- MFEM developer-guideline fit: keep code lean, simple, general, logically separated, and portable; suggest C++17 improvements when they clearly improve safety, clarity, or maintainability.
- New source files, examples, or miniapps: if a PR adds source/header files, verify they are properly wired into the relevant `makefile` and `CMakeLists.txt`, referenced in docs where applicable (including `doc/CodeDocumentation.dox`), and added to top-level `.gitignore` only when generated artifacts require it.
- Changelog: verify `CHANGELOG` is updated if the PR introduces significant new features or user-facing changes.
- MFEM conventions: use `real_t`; use `mfem::out`/`mfem::err` instead of `std::cout`/`std::cerr` in library code; flag large/binary files; if AI assistance is apparent but undisclosed, suggest following `CONTRIBUTING.md`.
- Edge cases: if the PR touches complex or error-prone areas, suggest additional tests for edge cases, failure modes, and parallel behavior.
-
-## Commenting guidelines
- Keep comments concise, actionable, and grounded in the diff.
- Focus on correctness, behavior changes, and user impact over style nits.
- Be professional, concise, collaborative, technically precise, and avoid unsupported assumptions.

-## Sanitizer Workflow for MFEM Verification
-
-This workflow validates MFEM unit tests, examples, and miniapps using sanitizer tools.
-
- `sanitizers.yml` orchestrates:
-  - Building and caching dependencies: HYPRE, METIS, LSAN suppression file, and LLVM libcxx.
-  - Launching fine-grained jobs for serial (ASAN, MSAN, UBSAN) and parallel (ASAN, UBSAN) sanitizers.
- `sanitize-tests.yml` is a reusable workflow accepting `par` mode (`true` for parallel) and `sanitizer` (ASAN, MSAN, or UBSAN) as inputs. It executes the following jobs:
-  - **Build**: Compiles the MFEM library with specified parallel and sanitizer settings.
-  - **Check**: Runs verification checks.
-  - Parallel jobs to test the following: **Examples**, **Miniapps** and **Unit tests**
-
-The workflow leverages composite actions in `.github/actions/sanitize/`:
-
- `config`: Centralizes settings for the sanitizer workflow.
- `mfem`: Manages the MFEM library build process.
- `mpi`: Installs MPI and applies additional compilation flags.
- `restore`: Restores the testing environment state.
- `setup`: Builds or restores cached dependencies.

-# DESCRIPTION:
-###############################################################################
 # General GitLab pipelines configurations for supercomputers and Linux clusters
-# at Lawrence Livermore National Laboratory (LLNL).
-# This entire pipeline is LLNL-specific
-#
-# Important note: This file is a template provided by llnl/radiuss-shared-ci.
-# Remains to set variable values, change the reference to the radiuss-shared-ci
-# repo, opt-in and out optional features. The project can then extend it with
-# additional stages.
-#
-# In addition, each project should copy over and complete:
-# - .gitlab/custom-jobs-and-variables.yml
-# - .gitlab/subscribed-pipelines.yml
-#
-# The jobs should be specified in a file local to the project,
-# - .gitlab/jobs/${CI_MACHINE}.yml
-# or generated (see LLNL/Umpire for an example).

+# at Lawrence Livermore National Laboratory (LLNL). This entire pipeline is
+# LLNL-specific!
+
+
+# The pipeline is divided into stages. Usually, jobs in a given stage wait for
+# the preceding stages to complete before to start. However, we sometimes use
+# the "needs" keyword and express the DAG of jobs for more efficiency.
+# - We use setup and setup_baseline phases to download content outside of mfem
+#   directory.
+# - Allocate/Release is where quartz resource are allocated/released once for all.
+# - Build and Test is where we build and MFEM for multiple toolchains.
+# - Baseline_checks gathers baseline-type test suites execution
+# - Baseline_publish, only available on master, allows to update baseline
+#   results
+stages:
+  - sub-pipelines

-###############################################################################
-# We define the following GitLab pipeline variables:
 variables:
-##### LC GITLAB CONFIGURATION
  CUSTOM_CI_BUILDS_DIR: "/usr/workspace/mfem/gitlab-runner"
-
-##### PROJECT VARIABLES
  USER_CI_TOP_DIR: "${CUSTOM_CI_BUILDS_DIR}/${GITLAB_USER_LOGIN}"

  AUTOTEST_ROOT: "${SHARED_REPOS_DIR}"

+  # used in '.gitlab/configs/<machine>-config.yml':
  MFEM_DATA_DIR: "${SHARED_REPOS_DIR}/mfem-data"
-# AUTOTEST: enable (ON/YES) or disable (any other value) test reporting. See
-# also AUTOTEST_COMMIT.
-  AUTOTEST: "OFF"
-# AUTOTEST_COMMIT: used only when AUTOTEST is set to ON/YES.
-# * If AUTOTEST_COMMIT is set to ON/YES, reporting jobs will commit their
-#   files to the MFEM/autotest repo.
-# * If AUTOTEST_COMMIT is NOT set to ON/YES, reporting jobs will NOT commit
-#   their files to the MFEM/autotest repo. Instead they will just show the
-#   contents of the report files and remove them.
-  AUTOTEST_COMMIT: "ON"
-# REBASELINE:
+
 # Defines the default choice for updating the saved baseline results. By default
 # the baseline can only be updated from the master branch. This variable offers
 # the option to manually ask for rebaselining from another branch if necessary.
-  REBASELINE: "OFF"
+  REBASELINE: "NO"
+  AUTOTEST: "NO"
+  # AUTOTEST_COMMIT: used only when AUTOTEST is set to YES.
+  # * If AUTOTEST_COMMIT is NOT set to NO, reporting jobs will commit their
+  #   files to the MFEM/autotest repo.
+  # * If AUTOTEST_COMMIT is set to NO, reporting jobs will NOT commit their
+  #   files to the MFEM/autotest repo. Instead they will just show the contents
+  #   of the report files and remove them.
+  AUTOTEST_COMMIT: "YES"

-##### SHARED_CI CONFIGURATION
-# Required information about GitHub repository
-  GITHUB_PROJECT_NAME: "mfem"
-  GITHUB_PROJECT_ORG: "MFEM"

-=================================
-RAJA uses CMake's built-in HIP support (added in CMake 3.21), while MFEM uses

-
-Specific options for Enzyme
-===========================
-To work properly, MFEM and Enzyme need to use the same LLVM/Clang configuration.

-
-   brew install enzyme

-
-   CXX = $(shell brew --prefix llvm@19)/bin/clang++
-
-in the user.mk file (adapted from config/defaults.mk, see the section "Building
-with GNU make" above). With MPI, it is convenient to set
-
-   MPICXX = OMPI_CXX=$(CXX) mpicxx
-
-for OpenMPI and
-
-   MPICXX = MPICH_CXX=$(CXX) mpicxx
-
-for MPICH.
-
-Additionally, the Enzyme directory needs to be set in user.mk as follows:
-
-   ENZYME_DIR = $(shell brew --prefix enzyme)
-
-Specifically, a full build on a Mac can be tested by adding the following
-user.mk file in the config/ directory
-
-   MFEM_USE_ENZYME = YES
-   ENZYME_DIR = $(shell brew --prefix enzyme)
-   LLVM_DIR = $(shell brew --prefix llvm@19)
