Replace the R9V radiance fork with the tcclaviger RDNA4 vLLM stack (the digest-pinned image the 2026-09-29 tuning campaign measured), serving orcarouter/Qwen3.8-Flash-Next-Uncensored-FP8 (131 shards, 172.8 GiB, already on disk) with MTP4 spec decode. Qualified by boot probe on 2026-09-29: - MAXLEN=200000 x SEQS=3 (600k total) at --kv-cache-dtype fp8 (q8/q8 KV): 'GPU KV cache size: 729,545 tokens; Maximum concurrency for 200,000 tokens per request: 3.65x' at KV_BYTES 7.2 GiB PER RANK. - KV_BYTES is per-rank: global 16G and 9G both OOM (worker tried to allocate the full size; ~7.5 GiB/rank is the ceiling with the arena). - prefetch OFF by law (telemetry: 36% precision, ~50% wasted traffic); TunableOp off (corrupts numerics). - decode at this shape: 42.94/34.55/36.09 tok/s; arena 6,032 slots. Trio: frank-primary.env (all FRANK_PRIMARY_* keys), serve-frank-primary.sh (direct podman run; entrypoint execs vllm serve; waits on the container), frank-primary.service (root unit, same ExecStop law, new container name frank-primary-qwen). Deployer gates rewritten (image digest + shard count + weight-map index). download-frank-primary.sh is now inventory/verify (repo is GATED — 401 anonymous, masked LFS hashes; payload already on disk). Seam rewritten for the new contract. Pre-cutover tag: frank-primary-r9v-q8-20260929.

# frank-primary.service — tcclaviger RDNA4 vLLM endpoint (orcarouter

# Qwen3.8-Flash-Next-Uncensored-FP8, MTP4 spec decode, KV q8/q8, 600k total
|
|
# context over 3 sessions, TP=2, tiered experts, 131-shard payload) on the
|
|
# 2x R9700 pair, dankserver :7770. 2026-09-29 cutover from the R9V radiance
|
|
# 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
|
|
# disk as rollback).
|
|
#
|
|
# 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.
