DFlash2 experiment declared failed 2026-10-01: the drafter serves and drafts (12.8 tok/s proposed) but acceptance is pinned at 1.0-1.38 on ALL text classes including verbatim repetition — the aux-hidden-state capture semantics are wrong (single-stream entering-state vs post-layer/comb is the untested alternative). At ~1.2 acceptance the 8-token verify tax makes decode 5x SLOWER than the 9.9-10.0 baseline (1.6-1.8 tok/s measured). Restores the verified 37-40 tok/s shape: qwen3.8-flash-next FP8, MTP4, prefetch off, 200k x 3 seqs, fp8 KV.

# fork (git tag frank-primary-r9v-q8-20260929 is the pre-cutover state; its

# launcher/shim/setup-state machinery is retired and the state dirs stay on

|
# Same port, same served alias; the harness models.yml id is unchanged.
|
|
# The serve script drives `podman run` directly (the image entrypoint execs
|
|
# `vllm serve`) and then waits on the container, so a crashed engine is a
|
|
# nonzero ExecStart and Restart=on-failure is real.

#
|
|
# WHY A ROOT UNIT (not a rootless quadlet): the tiered-expert shape pins tens
|
|
# of GiB of host RAM (the expert host slabs, ~20.5 GiB per rank of pinned
|
|
# anonymous memory). Pinned pages are charged against RLIMIT_MEMLOCK; dank's
|
|
# login session on this host carries 8 MiB and a user quadlet is capped by the
|
|
# user manager's own hard limit — raising that means restarting
|
|
# user@1000.service and bouncing every user container on the host. A root unit
|
|
# grants LimitMEMLOCK=infinity to the dank process via PID1, and the image
|
|
# stays in dank's rootless podman storage.
