+# NOTE: no --chat-template flag — let llama-server auto-detect Mistral-Small's
+# own embedded chat template from GGUF metadata.
+# NOTE: --host is the private LAN IP (10.1.71.130 by default), NOT 0.0.0.0.
+# NOTE: --parallel 1 is deliberate (plan §1/§2) — tool-calling profiles are
+# single-session-at-a-time per Claude Code profile; lower parallelism reduces
+# KV overhead and lowers hallucination surface from context bleed between
+# concurrent slots.
+# IMPORTANT: this endpoint MUST pass the plan §7 validation harness
+# (docs/validation-log.md in this role) before any Claude Code / tool-calling
+# Hermes profile is pointed at it. Mistral-Small shares lineage concerns
+# flagged for Qwen2.5/Qwen3 hallucinated tool_calls — do not assume safety.
