Collect references from Alibaba through OpenRouter with an explicit empty system message and no provider fallback. Validate token byte alignment and reject lossy Unicode metadata for API agreement while retaining continuation likelihood scoring.
Track 100 short and 12 long reference cases, Q2/Q4 default and quality controls, continued-prefill results, and independent long-context answers. Include collector and scorer regressions and document the hosted-checkpoint and precision limitations.
