Phase 2 revised: consolidate astro-orbiter to single Qwen2.5-14B-1M model (port 8002)

- Retire llama-server-aux (Phi-4, 8000) and llama-server-toolcall (Mistral-Small-24B, 8001): stopped, disabled, unit files removed from host and Ansible role
- Promote llama-server-qwen (Qwen2.5-14B-Instruct-1M, port 8002) to sole production model, serving both friday and war-machine Hermes profiles
- Verified live: n_ctx=65536/n_ctx_train=1010000, and tool_calls response via /v1/chat/completions probe (no hallucination)
- Deleted superseded GGUF weights (phi-4, mistral-small, orphaned base-Qwen, gemma-2-27b) from astro-orbiter, ~45GB reclaimed
- Updated friday and war-machine Hermes profile configs (model + compression + skills_hub aux) to point at 10.1.71.130:8002
- Ryan explicitly accepted single-model tradeoffs for both profiles

 # FILE: roles/llm-inference-multimodel/tasks/systemd.yml
-# DESCRIPTION: Phase 2 — template + deploy both unit files.
-#              DELIBERATELY DOES NOT START OR ENABLE either service — that is
-#              Phase 4 (verify.yml)'s job, after Phase 3 firewall scoping is
-#              in place. This keeps "units land on disk" and "processes
-#              actually bind ports and load 20+GB into VRAM" as separately
-#              reviewable checkpoints per Ryan's iterative-build preference.
+# DESCRIPTION: Phase 2 (REVISED 2026-08-06) — consolidated to a single
+#              production unit: llama-server-qwen (Qwen2.5-14B-Instruct-1M,
+#              port 8002), serving BOTH the friday and war-machine Hermes
+#              profiles. Ryan explicitly accepted the tradeoffs of running
+#              one model for both profiles instead of the original
+#              aux+toolcall two-model split.
 #
-#              Two independent units (llama-server-aux.service,
-#              llama-server-toolcall.service) — NOT one unit with two
-#              ExecStarts — so either can be stopped/restarted without
-#              affecting the other (plan §2, §6 rollback requirement).
+#              llama-server-aux (Phi-4, port 8000) and llama-server-toolcall
+#              (Mistral-Small-24B, port 8001) are RETIRED: services stopped
+#              + disabled, unit files removed from astro-orbiter, and their
+#              GGUF weights deleted from /opt/models (~45GB reclaimed).
+#              Ansible no longer templates or manages either unit — see git
+#              log for the prior task definitions if a future rollback needs
+#              them restored.
 #
-#              The pre-existing Gemma unit (whatever discover.yml found it to
-#              be) is never templated, restarted, or disabled by this file.
+#              The pre-existing Gemma unit/weights (llama-server.service,
+#              gemma-2-27b-it-Q4_K_M.gguf) were ALSO removed as part of this
+#              consolidation (superseded baseline, no longer a rollback
+#              target once Qwen was accepted as sole production model).
