Lays the dormant data-plane foundation for Sencho Mesh. The pilot tunnel
gains TCP forwarding frames (tcp_open / tcp_open_ack / tcp_close JSON
plus a 0x04 TcpData binary type) and a TcpStream surface on the bridge
so a future MeshService can ride the existing WSS tunnel for cross-node
container traffic. The agent rejects every tcp_open with mesh_not_enabled
until a follow-up PR wires the Dockerode resolver gated by a
mesh_stacks opt-in table; ships dormant.
A new top-level mesh-sidecar/ package provides the per-node container
that will host the L4 forwarder + control WS in production. Built as a
small Node 22 alpine image and published in lockstep with the main
sencho image via a parallel docker-publish workflow job.
Tests cover protocol roundtrips on both packages and the sidecar
forwarder end-to-end including resolve, splice, close, and stats.
* feat: pilot agent outbound-mode for remote nodes
Adds a second mode for managing remote nodes: the agent dials an outbound
WebSocket tunnel to the primary, so the remote host no longer needs an
inbound port, a reachable URL, or its own TLS certificate. Works behind
NAT, residential routers, and corporate firewalls.
The primary multiplexes HTTP and WebSocket requests over a single tunnel
via a hybrid JSON + binary frame protocol, bridged through a per-tunnel
loopback server so existing proxy and upgrade handlers route pilot-mode
nodes identically to proxy-mode ones.
Enrollment uses a single-use 15-minute pilot_enroll JWT exchanged for a
long-lived pilot_tunnel credential on first connect. Proxy mode continues
to work unchanged and both modes are supported side-by-side.
* test(e2e): switch to proxy mode before asserting api_url field
Remote nodes default to Pilot Agent mode, which hides the api_url input.
The SSRF-validation tests need proxy mode, so the helper now selects
Distributed API Proxy after picking Remote type before asserting the
field is visible.
* fix(e2e): wire Combobox id prop so node-mode selector resolves
The Combobox trigger button had no id, leaving its Label orphaned and
making getByRole name-based lookups fail. Adding id to the primitive,
passing id="node-mode" from NodeManager, and updating the E2E helper to
use #node-mode fixes both the a11y regression and the CI timeout.
