GET /api/premium/research/milestones
unprobed
Last 30 days of arXiv preprints flagged as milestone candidates by an offline Qwen 3.6 27B per-paper extraction pass. Each paper carries structured reasoning naming the benchmark + quantified delta, model release, or novel architecture justification. Conservative; false positives are worse than false negatives.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
