# Spa-Bench physical rollouts — VLA-0 (partial)

Physical SO-101 rollout recordings for the VLA-0 Spa-Bench checkpoint at the
end of epoch 12.

## Scope and counts

This is a partial familiar/in-distribution baseline, not a complete Spa-Bench
evaluation. It contains **72 episodes**, with at least ten from each of the six
task families, plus **11,051 frames, 51 unique instruction strings, two 480×640
RGB streams, and six-dimensional state/action at 10 FPS**. It contains no OOD
or additional diagnostic trials.

The checkpoint completed **0/72 trials (0%)**. VLA-0 received a 90-second
rollout limit because autoregressive action generation was slower than the
other evaluated policies. Because coverage is partial, it is excluded from the
report's full OOD and diagnostic comparisons.

Outcome labels and groupings are maintained in the
[Spa-Bench evaluation spreadsheets](https://github.com/justintiensmith/Imperial-Thesis/tree/main/spreadsheets),
not as a frame-level success field in this dataset.

## Structure and use

Each trajectory stores the instruction/task index, six absolute SO-101 joint
positions for state and action, and synchronized middle/wrist video. This
release supports audit, integration debugging, and qualitative failure
analysis. It must not be interpreted as an OOD benchmark result or a general
assessment of the VLA-0 method.

Do not train on these trajectories and report them as held-out performance.
Robot deployment requires safeguards and human supervision.
