Quick note: To configure/change the bridge port number from default 3100 to e.g. 3101, or run the bridge from a different host other than the IRIS server:

1. 1. Update bridge port
   	File: workpath/AIAgent/bridge/.env
   	Set: PORT=3101
   	If .env is missing, create it from .env.example.
   
   2. Restart bridge
   	From workpath/AIAgent/bridge, run:
   	npm install
   	npm run build
   	npm start
   	Verify bridge health
   	Run: curl http://localhost:3101/api/health
   	Expected: healthy response (status ok).
   
   3. Update IRIS setting used by CSP
   	In IRIS terminal, run:
   	do ##class(Ens.Config.DefaultSettings).SetValue("AIAgent","BridgeURL","http://localhost:3101")
   
   4. Keep global config in sync (recommended)
   	In IRIS terminal, run:
   	set ^AIAgent.Config("BridgeURL")="http://localhost:3101"
   
   5. Verify IRIS is using new URL
   	In IRIS terminal, run:
   	write ##class(AIAgent.Engine.BridgeClient).GetBridgeURL(),!
   	
   	zw ##class(AIAgent.Engine.BridgeClient).HealthCheck()
   	Expected: URL is http://localhost:3101 and health is reachable.
   
   6. Run E2E Test in IRIS
   
   	do ##class(AIAgent.Test.E2E).Run("http://localhost:3101")
   	
   7 Run Node E2E Test(from workpath/AIAgent/bridge):
   	$env:BRIDGE_URL="http://localhost:3101"
   	npm run e2e:sample
   	npm run e2e:realworld
   
   8. If bridge is on another machine
   	Use http://<bridge-host>:3101 instead of localhost in previous steps, and ensure firewall/network allows TCP 3101.
