frank-large: cut over to halogen container (qwen3.8-27b .hgn + DFlash2)
Runtime swap ROCmFPX llama.cpp -> peonist-ai/halogen (image digest dc0a39a0, tag 0.1.4), serving qwen3.8-27b-p1w4d-d2.hgn (33.4 GiB, the .hgn format loads in no other engine) with HALOGEN_DRAFTER=2 (DFlash2) on ONE slot of 200700 ctx: slots>1 disables the drafter (engine law). Accepted: TEXT-ONLY (vision encoder ignored; frank-small owns images) and the censored base (rollback = revert this commit; payload, fork build and build-rocmfpx.sh pin stay on disk). - serve script: podman run under the root unit, exec podman wait so Restart=always is real; gates image digest, checkpoint byte-count, flat regular-file tokenizer, GPU nodes; engine stdout to log. - deploy handler: gates the artifacts, sweeps the legacy bare llama-server + old container name by NAME (never pkill llama-server: frank-small), retires the 2026-09 quadlet, port cutover 7770. - fetch script: -C - resume, -f, byte count, sha256, --verify-only. - seam rewritten (17 tests): halogen is now the deployed runtime.

# frank-large is the ROCmFPX fork of llama.cpp (kingjones30/ROCmFPX, pinned by

# Strix Halo iGPU. It is a ROOT unit: the runtime is a native binary linked

# frank-large is the halogen CONTAINER (ghcr.io/peonist-ai/halogen,
|

# digest-pinned through scripts/frank-large.env) serving
|

# peonist-ai/halogen-qwen3.8-27b — qwen3.8-27b-p1w4d-d2.hgn, 33.4 GiB,
|

# DFlash2 spec decode, 1 slot x 200700, text-only — on the Strix Halo
|

# iGPU. It stays a ROOT unit because the serve script drives `podman run`
|

# directly (the frank-primary pattern): relink_unit points
|

# /etc/systemd/system/frank-large.service at the repo file, boot

# persistence is that unit's [Install], and LimitMEMLOCK=infinity is

# fleet parity. 2026-10-05 cutover from the ROCmFPX llama.cpp shape —
|

# rollback = revert the swap commit's trio; that payload, its draft head
|

# and the fork build all stay on disk
|
||||
# (~/models/kingjones-Qwen3.8-27B-Uncensored-ROCmFP4-STRIX-MTP,

# The runtime gate matters as much as the payload gate: the fork is built from

# source on this host, and the payload is ftype 114 (tensor types 102
|
||||
# GGML_TYPE_Q6_0_ROCMFPX and 103 GGML_TYPE_Q8_0_ROCMFPX) which only this fork
|

# can read — so a machine whose /home/dank/GitPackages tree was never built has
|

# a unit that can never become healthy, and a green deploy would leave the
|

# endpoint dark.

# It replaces the ALIGNED kingjones Q8_0_ROCMFPX_AGENT file (rollback target:

# ~/models/kingjones-Qwen3.8-27B-ROCmFP4-STRIX-MTP, where this payload's
|

# draft-head hardlink also lives). The port gate is the same as every cutover
|
||||
# since 2026-09-16: nothing starts until 7770 is released.
