    <description>Most of the wait before our AI's first word on a repeat turn was the engine re-reading text it had already read.</description>
    <nyaa:claim>On a turn whose context hadn't changed, most of the time to the first token went to re-reading context the engine had already read.</nyaa:claim>
    <nyaa:measurement>Our engine's median time to first token was 1.27 s (397 requests, all traffic). Most of it traced to cache-block rounding, an estimated 0.8-1.5 s per turn. A config change then cut a test turn from 0.88 s to 0.16 s.</nyaa:measurement>
    <nyaa:method>live engine metrics on our own machine, 2026-10-09; the rounding share is an estimate from the uncached-token distribution, not a direct measurement. People turns were not measured on this engine.</nyaa:method>
    <nyaa:falsifier>If an exact end-of-request cache checkpoint does not remove most of that re-read time on byte-stable turns, the claim is wrong.</nyaa:falsifier>
