→ Immutable
Once an experiment is committed, its design is frozen. Once it completes, its outputs (inputs, hyperparameters, metrics, and artifacts) are locked.
→ Graph lineage
Each run records the prior runs it descends from. Improvements over a baseline are explicit, not narrated after the fact.
→ Searchable
Find every prior run that touched the same dataset, eval, or architecture — across teams, across years.
→ Auditable
Connect datasets to every downstream trained model to streamline compliance reporting.
