Eval and judge agent
eval-judge
Scores a trace or a patch against a rubric, without the gold label in its prompt, and records the harness version.
Needs below are the JTBD ids already listed on this class, capped at 6. The pick is the current Depot Pick. The cheapest line is that job's matching sourced SKU, or unavailable. A free row is listed only when its jtbd ids include that job. This page does not rescore. cost=free does not hide that pick and does not turn a cheap paid SKU into a free one.

Failure modes
Eval contamination eval-contamination
Keep gold labels out of the agent prompt. Store the harness version beside the score. Do not compare a number across a benchmark revision without saying the revision changed.
Non-determinism non-determinism
Run the task more than once and compare the end state, not a single transcript. Record the trial count next to any success rate you cite.
Weak verification weak-verification
Success requires an end-state check the agent does not grade for itself: tests, a database diff, or a separate judge that cannot see the gold label.
Observability gap observability-gap
Alert on a drop in trace ingestion and on certificate expiry for the trace host. Do not treat a missing trace as a successful quiet run.
Benchmark protocol mismatch benchmark-protocol-mismatch
Store assisted-or-not, subset, and harness version beside every cited score. Refuse a ranking that mixes those fields.
Inter-agent misalignment inter-agent-misalignment
Log the assigned subtask next to the worker's stated result. The lead rejects a result that does not match the assignment.
