Adil Hafeez	da9792c2dd	rename session pinning to model affinity with x-model-affinity header	2026-04-08 15:23:53 -07:00
Adil Hafeez	5789694d2f	rename x-session-id to x-routing-session-id and fix routing config field name	2026-04-08 12:39:43 -07:00
Adil Hafeez	0105897692	add session pinning to llm_chat handler and rewrite session pinning demo ... - extend brightstaff llm_chat_inner to extract X-Session-Id, check the session cache before routing, and cache the result afterward — same pattern as routing_service.rs - replace old urllib-based demo with a real FastAPI research agent that runs 3 independent tool-calling tasks with alternating intents so Plano routes to different models; demo.py is a pure httpx client that shows the routing trace side-by-side with and without session pinning	2026-03-26 16:44:05 -07:00
