Comparison Editor
Comparison isn't one single view in Tensormorph's View menu - the dedicated 3D view for it is called Diff, and the same comparison mode is also available as a shading option within the 2D and 1D view families. "Comparison Editor" here refers to that cross-cutting capability, not a single panel distinct from everything described elsewhere in this documentation.
Once two checkpoints are loaded as an aligned pair, every view in Tensormorph gains a comparison mode, rather than requiring you to switch into a separate comparison-specific application.
Loading a pair
Comparison starts with picking a baseline and one or more candidates - the baseline is the fixed reference every candidate is visually differenced against, distinguished consistently across every view once set (mirroring the "pin a baseline" pattern common in experiment-comparison tools). Loading a pair triggers alignment (see Model Diff) before any diff view becomes available.
Where comparison shows up
| View | Comparison mode |
|---|---|
| Diff (3D) | The dedicated 3D view for browsing a whole-model diff spatially - structurally identical to the Architecture view, shaded by difference instead of by value. |
| Matrix and Heatmap (2D) | The Diff and Correlation shading modes - see Matrix and Heatmap Editor. |
| Signal and Distribution (1D) | The Delta sub-mode, and overlaid distributions - see Histograms and Distributions. |
| Outliner | A per-tensor changed/unchanged indicator, so you can scan the tree for what moved without opening every tensor individually. |
From diff to decision
A comparison surfaces where two checkpoints differ; what to do about it depends on context - accepting a candidate as a promoted result, flagging a merge conflict if the pair came from diverging branches, or feeding the diff into a validation suite (see CI Validation) rather than reviewing it by hand every time.
