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.
Fetches into /home/dank/models/Qwen3.8-Flash-Next-GGUF/ keeping the Hub
layout: the six Q8_0 split parts (175.30 GiB — never concatenated, part
1's header advertises file_count=6), the shared Q8_0 MTP drafter head
(2.6 GiB — "shared" borrows the target's embeddings; unsloth's MTP guide
names it the recommended head), and the BF16 vision projector. Total
191,919,144,448 bytes.
Sizes and sha256s captured from the resolve endpoint's x-linked-etag/
x-linked-size on 2026-09-26; every artifact is checked for exact byte
count AND sha256, curl -f so an auth error fails instead of writing the
error body, resumable via -C -. The repo is public: no token machinery.
