Struct NodeRecord 

pub struct NodeRecord {
    pub name: String<64>,
    pub namespace: String<64>,
    pub rmw_name: Option<String<32>>,
    pub locator: Option<String<128>>,
    pub default_sched: SchedContextId,
    pub session_idx: u8,
}

Per-Node metadata stored inside the Executor.

Phase 104.C.2 keeps the shape minimal — name, namespace, default SchedContext, optional rmw-name for diagnostics. Future items: per-Node session reference (104.C.3), per-Node liveliness state, per-Node parameter overrides.

Fields

name: String<64>

namespace: String<64>

rmw_name: Option<String<32>>

RMW backend the Node was created against. None for the implicit primary Node populated from Executor::open.

locator: Option<String<128>>

Per-Node locator override. None = use the Executor’s session-level locator.

default_sched: SchedContextId

Default SchedContext for handles created via this Node. Handles may override per-call. SchedContextId::default() = the executor’s auto-created Fifo slot (slot 0).

session_idx: u8

Phase 104.C.3 — session-slot index. 0 resolves to the Executor’s primary session field; N >= 1 resolves to extra_sessions[N-1]. Each Node may bind to a different session, enabling multi-RMW bridges in one Executor.
