# Tensor Cards

A structured per-tensor card is not a confirmed part of Tensormorph's design - this page covers the confirmed provenance signals a tensor card would plausibly be built from, not a finished feature.

Where a [Model Card](/docs/hub-and-collaboration/model-cards) would describe a whole checkpoint, a Tensor Card is the same idea at finer grain: structured provenance for one specific tensor - where it came from, what's been done to it, and what it's derived from.

## What's already trackable, per tensor, today

Several confirmed pieces of Tensormorph's design already amount to per-tensor provenance, even without a unified "card" object pulling them together:

-   **Lob's commit pin** (see [Versions and Branches](/docs/hub-and-collaboration/versions-and-branches#commit-pins-and-stale-notes)) - which commit a tensor's containing checkpoint was materialized from.
-   **A morph's `recipe.json`** (see [Model Morphing](/docs/core-concepts/model-morphing#expression-dag-not-an-edit-history)) - if a tensor is the output of a morph, the recipe that produced it.
-   **Quantization metadata** (see [Dtype and Quantization](/docs/core-concepts/dtype-and-quantization)) - scale, zero-point, and granularity, wherever a tensor is quantized.
-   **Format-native metadata** - whatever the source format itself carries (see [Model Cards](/docs/hub-and-collaboration/model-cards#whats-confirmed-today)).

## What a card would add

A Tensor Card would plausibly present these together as one readable summary attached to a specific tensor's Inspector panel entry, rather than requiring you to separately check the commit history, the recipe file, and the format metadata to reconstruct a tensor's story. That presentation layer isn't confirmed to exist yet - the underlying data it would draw from largely already does.
