| # Complete the Native Multi-Equilibrium TERPSICHORE Workflow |
|
|
| The supplied source is a substantial DESC-native migration of a three-dimensional |
| ideal-MHD stability workflow. It can load and represent several equilibrium |
| families, and it contains lower-level geometry, spectral, operator, solver, and |
| energy components. It does not yet provide one complete and trustworthy native |
| workflow for a researcher who submits a new supported VMEC/DESC equilibrium. |
|
|
| Inspect the source and run: |
|
|
| ```bash |
| python reproduce.py |
| python reproduce.py --check |
| ``` |
|
|
| The public reproduction uses the same high-level input path for an axisymmetric |
| control equilibrium and a genuinely three-dimensional equilibrium. It reports |
| whether each end-to-end native calculation completes and records the resulting |
| finite stability scalars without inferring a repair location from internal |
| source structure. A candidate scientific-chain exception or non-finite result |
| is reported only as a coarse scientific failure; fixture, path, import, and |
| dependency failures are reported separately as runner failures. |
|
|
| Complete the implementation so that supported stellarator-symmetric equilibria |
| can traverse this scientific workflow through one native path. The implementation |
| must preserve the meaning of intermediate quantities and remain general across |
| equilibrium metadata, field periods, spectral content, and discretization. |
|
|
| Your implementation will be evaluated on additional equilibria, resolution and |
| mode changes, a full-domain vacuum/wall configuration, and an unsupported |
| asymmetric representation that must be rejected explicitly. |
|
|
| Do not: |
|
|
| - hard-code fixture names, dimensions, field periods, arrays, or final scalars; |
| - use precomputed comparison arrays as inputs to the production calculation; |
| - call the external TERPSICHORE executable as the implementation; |
| - make a report claim success when an upstream scientific stage is unavailable; |
| - silently discard asymmetric Fourier content; |
| - solve only the public cases or only the final growth-rate scalar. |
|
|
| The task workspace and fixtures are available offline. The goal is capability |
| completion, not a local text or branch patch. |
