Struct FlowId 

pub struct FlowId(/* private fields */);

Identifier of a flow — Byteflow’s unit of concurrent work.

Host APIs and the directory key on this type. Inside messages it appears as crate::Value::Pid (Message.sender / msg_sender) for identity. Bytecode addressing uses crate::Value::Cap (FlowCap) — a Pid is not a Send/Ask authority token.

Backed by a single global, wait-free AtomicU64 counter rather than anything derived from memory addresses: ids must stay unique for the lifetime of the runtime and must never be reused, or a stale id in someone’s registers could address a different later flow (ABA) via the host/Directory path.
