 # herocoordinator
 
+## Demo setup
+
+A python script is provided in the [scripts directory](./scripts/supervisor_flow_demo.py). This script
+generates some demo jobs to be run by [a supervisor](https://git.ourworld.tf/herocode/supervisor).
+Communication happens over [mycelium](https://github.com/threefoldtech/mycelium). To run the demo a
+supervisor must be running, which uses a mycelium instance to read and write messages. A __different__
+mycelium instance needs to run for the coordinator (the supervisor can run on a different host than
+the coordinator, so long as the 2 mycelium instances used can reach eachother).
+
+An example of a local setup:
+
+```bash
+# Run a redis docker
+docker run -it -d -p 6379:6379 --name redis redis
+# Spawn mycelium node 1 with default settings. This also creates a TUN interface though that is not
+# necessary for the messages
+mycelium
+# Spawn mycelium node 2, connect to the first node
+mycelium --key-file key.bin --peers tcp://127.0.0.1:9651 --disable-quic --disable-peer-discovery --api-addr 127.0.0.1:9989 --jsonrpc-addr 127.0.0.1:9990 --no-tun -t 8651
+# Start the supervisor
+supervisor --admin-secret admin123 --user-secret user123 --register-secret register123 --mycelium-url http://127.0.0.1:9990 --topic supervisor.rpc
+# Start the coordinator
+cargo run # (alternatively if a compiled binary is present that can be run)
+# Finally, invoke the demo script
+python3 scripts/supervisor_flow_demo.py
+```

+SupervisorClient reuse cache (Router-local):
+
+Rationale:
+- SupervisorClient maintains an internal JSON-RPC id_counter per instance.
+- Rebuilding a client for each message resets this counter, causing inner JSON-RPC ids to restart at 1.
+- We reuse one SupervisorClient per (destination, topic, secret) to preserve monotonically increasing ids.
+
+Scope:
+- Cache is per Router loop (and a separate one for the inbound listener).
+- If cross-loop/process reuse becomes necessary later, promote to a process-global cache.
+
+Keying:
+- Key: destination + topic + secret-presence (secret content hashed; not stored in plaintext).
+
+Concurrency:
+- tokio::Mutex protects a HashMap<String, Arc<SupervisorClient>>.
+- Values are Arc so call sites clone cheaply and share the same id_counter.
