band: 'batches of 2-8 users; batch 7 pads onto the 48-row batch-8 graph; draft length stays 5 (6 rows per request). Draft length 7 and the Mia weights are NOT part of this selection.'
lane: '2-8 user decode lane = experiments/ds1017-r2-b2-b8 (separate source, DEFAULT OFF). The published C1 source stays the one-user bundle in experiments/ds1017-native-mixed-and-split (native mixed experts, split attention, captured K5 drafter).'
image: "UNAVAILABLE (never published): the author states 'There is still no pullable image' (SERVING-2026-10-26.md). The only image identifier in the stack, sha256:55d2bd9a6664aea2540e3f8e373d784b88420d35c3cedefc9f03923cd687b6f5, is a LOCAL docker image id recorded for the measured serve (1017 repo README.md:93), not a registry reference; the site's image_digest is null. Cloning the repo does not turn the lane on: no image boots the 2-8 user graphs or the sampled drafter yet."

New attention for every batch size; a temperature-0 request stays greedy at every batch size.'
