Frank fece3ffdd0 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.

# download-frank-large-halogen.sh — fetch frank-large's halogen payload:
# the qwen3.8-27b .hgn checkpoint and the export tokenizer, from the
# PUBLIC peonist-ai/halogen-qwen3.8-27b repo (no token — and per the fleet
# secret law, none would ever touch argv).
#
# The fetch law, same as every sibling script: curl -f (an access error
# must not become a "successful" 153-byte artifact), exact byte count from
# the model card, LFS sha256 verification, --verify-only to re-check an
# existing payload without downloading.
