Development Priorities

[cortner]

Linear models

• get splines working with ET backend
• introduce new pair potential model via V2rep + V2smooth (not compatible with old ACE1 style models)

Non-linear models

• Fully non-linear ACE fits - end-to-end Zygote-based AD through Lux-based ACE models
• Pre-trained/exported embeddings (e.g. from MACE) then used for linear ACE models or TRACE models
• TRACE

General maintainance

• Deprecate then drop support for pre-Lux/ET models
• Bring back purification
