net-cli 0.27.0-beta.1

//! End-to-end remote-attach integration test for `net aggregator`.
//!
//! Boots an aggregator-daemon in-process via `boot()`, then drives
//! the CLI binary as a subprocess (`assert_cmd`) with the daemon's
//! `--print-bootstrap` triple injected as `--node-addr` /
//! `--node-pubkey` / `--node-id` / `--psk-hex`. Each verb's exit
//! code + stdout JSON shape is asserted against the daemon's
//! registry state.
//!
//! # Routed-handshake bootstrap
//!
//! The CLI's `CliContext::build_with_remote` uses
//! [`net_sdk::Mesh::connect_via`] (routed handshake) rather than
//! the direct path. Direct handshakes from new peers to a
//! started daemon are dropped by the dispatch loop (only
//! `pending_direct_initiators` exists, not a responder-side
//! registry — see `mesh.rs:2409-2417`). The routed path's
//! `handle_routed_handshake` Case 2 picks up msg1 from a fresh
//! initiator, completes the handshake, and registers the peer
//! against a running dispatch loop.
//!
//! Pin set:
//! - `ls --remote` against a daemon with two static groups
//! - `spawn` against a configured template adds a third group
//! - `scale` (interim Unregister + Spawn) resizes a group
//! - bad pubkey / missing flag map to typed exit codes
//! - `query` is `#[ignore]`'d — needs replica node_id discovery
//!   (the fold.query service handler is keyed on each replica's
//!   keypair-derived id, not the daemon's main mesh id)
