Evidence Trajectory

How does target evidence evolve across depth?

Evidence Trajectory result for the image_pattern_cnn2d fixture
Real output from the small deterministic CNN-2D documentation fixture.

What it shows

The selected target's evidence trajectory through layers.

Claim boundary

This is evidence for this input and model state, not a universal statement about every input.

Run this with the installed CLI

Point VRAVEN at a validated model bundle. This produces one focused HTML report and works after a normal PyPI installation.

vraven analyse ./my-model \
  --task explain \
  --preset standard \
  --format html \
  --output vraven-report.html

Start with the model-folder guide if your bundle is not prepared yet. The larger documentation fixture is a contributor workflow described in Develop from source.

How to read the result

  1. Start with the title and target metadata in the generated report.
  2. Read the strongest structures first, then inspect weaker or opposing evidence.
  3. Check the stated evidence level and status before treating a relationship as causal or formal.
  4. Retain the trace, model version, preprocessing, and VRAVEN version with any published claim.
Reproducibility noteThe screenshot is public documentation evidence. The source run remains local-first; raw provenance files are not published because they can contain machine paths.
