# Seam: the frank-zealot llama.cpp root unit on dankclaw.
# frank-zealot is the RTX 3090 endpoint; since 2026-10-07 it serves
# HauhauCS's Qwen3.5-9B-Uncensored-HauhauCS-Aggressive (Q6_K, qwen35 hybrid:
# 32 layers, 8 full-attention + 24 Gated DeltaNet, no MTP tensors in the file)
# via the CUDA (sm_86) build of llama.cpp master: TWO 200,704-token
# conversations (--ctx-size 401408 --parallel 2), exact f16 K + f16 V under
# flash attention, the publisher's own BF16 vision projector, and MTP off —
# the file carries no nextn/mtp tensors, so there is no in-file head to draft
# with. Log verbosity 4 ships so the VRAM-fit forensics (KV layout, buffer
# sizes, graph capture) land in the journal.
# This seam runs the serve script against a stub engine and asserts on the
# argv it actually execs, so what is pinned is the command the operator gets.
