Agent Experiment 0.7.2

Agent Experiment 0.7.2

Maintenance release. Three dependencies move: Agent Judge 0.15.1 → 0.15.2, the Agent Journal
family 1.8.2 → 1.9.0, Agent Workflow 0.12.1 → 0.12.2.

This is the release the bug-fix wave was for. Agent Experiment is where the scores are produced, so
it is the component whose numbers were most affected.

If you have collected experiment scores, read this

Agent Judge 0.15.0 and 0.15.1 could silently drop a judge from a parallel jury. The jury still
returned a verdict, still named every configured judge, and did not warn — the aggregate was simply
computed from the judges that survived. It was found independently downstream, where two of six
judges turned out never to have run.

Any experiment score produced through a parallel jury on Agent Experiment 0.7.0 or 0.7.1 may have
been computed from fewer judges than it reports. Treat those scores as suspect and re-run anything
you are relying on.

The experiment reached the judge by two paths — directly, and transitively through Agent Workflow's
JudgeGate. Both are repinned here, so the resolved graph now carries one judge version throughout.
Repinning only the direct dependency would have left the defective judge arriving through workflow.

Capture columns you were missing

Agent Journal 1.9.0 adds the per-turn cost vector (input / output / thinking / cache-creation /
cache-read), vendor-neutral stop reasons, and tool-call turn ordinals and durations. Every one of
those fields was already being reported by the provider and discarded at parse time.

Capture is one-shot per run: trajectories recorded on 1.8.2 are permanently missing those columns
and cannot be backfilled. Runs recorded from 0.7.2 onward will have them.

What changed

• Repins agent-judge 0.15.1 → 0.15.2
• Repins claude-code-capture / journal-core 1.8.2 → 1.9.0
• Repins agent-workflow 0.12.1 → 0.12.2

No API change in Agent Experiment itself. All dependency changes are additive; no schema key was
renamed or removed.

Upgrading

Drop-in. Take it from AgentWorks BOM 1.19.0 or later, or bump the experiment-* coordinates to 0.7.2.
