Fixes SF-3393
claude-code-usageonly carriedmodelUsagewhen there was per-model usage to report, but the server treats that property as required. A run that ends before any model round-trip (auth failure, cancellation, injection check disabled) sends summary-only and the server-side mapper throws, dropping the whole service message batch — including the transcript.Now always sends the attribute, empty list included, so the run summary still gets through. Logs a verbose line when there's no per-model usage.
No — the server already requires
modelUsage; this makes Calamari always send it. A separate server-side change to stop the mapper throwing on old agents is worth doing, tracked by LEV-1350.🤖 Generated with Claude Code
