-  `ghcr.io/peonist-ai/halogen` image serving `peonist-ai/halogen-qwen3.8-27b`
-  (`qwen3.8-27b-p1w4d-d2.hgn`, 33.4 GiB) with the DFlash2 drafter on ONE slot
-  of 200,700 ctx (slots>1 disables speculation — engine law). Publisher card
-  31.7 t/s mean across eight text workloads. Accepted tradeoffs: TEXT-ONLY
-  (the engine ignores the vision encoder; frank-small owns images) and the
-  CENSORED base model (the ROCmFPX AGENT file was Uncensored by construction).
-  No server-side sampler — the thinking recipe rides the wire in models.yml.
-  Rollback: revert the swap commit; the ROCmFPX payload + fork build +
-  `build-rocmfpx.sh` pin all remain on disk
-  Tuned 2026-10-06: `HALOGEN_CACHE_MB=16384` pins the prompt cache —
-  auto was OFF at the 36.9 GB two-entry floor, so every deep request
-  re-prefilled its 79-81k context (85-180 s each); a 17.3k cold prefill
-  of 27.0 s now resumes in 1.7 s on the warm turn (cache_n 16,384). The
-  serve script captures the engine ledger on disk (foreground `podman
-  run`; the `-d` era wrote only the container ID). Decode-at-depth is
-  structural: 3.3-3.8 t/s at 80k vs 30-50 shallow; no supported flag
-  touches it.
-  The FA tile lever from upstream issue #12 (`HALOGEN_FA_TQ=256`) was
-  A/B'd at 80k on 2026-10-06: decode ±0.3 % (rejected), prefill −9.5 %
-  on this topology — the default tile stands. The deep harness roles
-  (`slow`, `advisor`) rerouted to frank-primary; frank-large keeps
-  OpenWebUI and shallow callers.
