Frank 795b0b3a5e frank-large: document the ik_llama.cpp deployment and the decode performance campaign

- Runbook with the measured envelope (prefill ~192 t/s at the VNNI ceiling;
  decode ~3.8-4.3 t/s gated by 100 backend splits/token, GPU 95% idle), the
  root-cause evidence chain, tuning levers, and co-tenancy traps
- AGENTS.md: fleet topology row + Active Services section for the ik
  deployment; halogen demoted to rollback; bench policy unit type fixed
- LLM + root indexes relinked (frank-large-ik-uncensored ACTIVE,
  halogen-flash-server retired)

Raw Blame History

LLM Fleet — Knowledge Base

Documentation for the LLM inference fleet on the two hosts (2026-09-16): charlie12345/ROCmFPX llama.cpp on Dankserver (frank-medium, kingjones777 Qwen3.8-27B-ROCmFPX-Q8_0-AGENT on 2x Radeon AI PRO R9700) and ik_llama.cpp on Dankclaw (frank-large, mradermacher Qwen3.8-Flash-Next- Uncensored i1-Q4_K_M on the RTX 3090 + Strix Halo hybrid).

2026-08-22: the former vllmScripts repository is merged into the serverAppConfigs repository. This knowledge base moved from the old repo's serverAppConfigs-docs/ root to serverAppConfigs-docs/LLM/. The fleet scripts and units now live in the repo's scripts/ directory.
