+# llama.cpp server on .150 (Docker Desktop) — inference backend for hermes/FRIDAY.
+#
+# Replaced ollama as the *serving* engine on 2026-08-21 after a head-to-head
+# benchmark on the same GGUF, same 64k context, same GPU:
+#   ollama (f16 KV):    15.8 tok/s aggregate, 16.5 sustained, 23207 MiB VRAM
+#   llama.cpp (q8_0 KV): 39.7 tok/s aggregate, 39.9 sustained, 19545 MiB VRAM
+# The difference is the quantized KV cache: it drops the footprint from 23.2GB
+# to 18.6GB, so the whole model fits on the 3090 instead of spilling layers to
+# CPU. Ollama exposes no knob for KV quantization.
+#
+# Image is pinned BY DIGEST on purpose — `:server-cuda` is a moving tag, and
+# this homelab has been bitten by tag-rot three times (synapse, gitea, openclaw).
