Channel wraps the post-handshake socket and carries 4-byte length-
prefixed distribution messages: pass-through byte ('p') + ETF control
tuple + optional payload term.
API surface:
send_raw / recv_raw -- raw 4-byte framed bytes, empty == net_tick
send_tick -- send keepalive frame
send_control / recv_message -- structured control + payload
send_reg_send -- helper for the REG_SEND case (FromPid,
registered name, payload)
recv_message() transparently skips inbound ticks; callers wanting tick
awareness use recv_raw().
etf.decode_term(data, offset) exposed as a streaming decoder so the
channel can read control + payload back-to-back from one frame body.
Tests:
- pure encode/decode round-trips
- socketpair tests for framing, ticks, helper signatures
- live end-to-end against an erl node with a registered echo process:
EPMD -> handshake -> REG_SEND -> recv reply, payload matches
- boot script writes a /tmp ready-flag after registering `echo`;
fixture waits for both EPMD registration AND the flag to dodge
the race where EPMD registers the node before -eval runs
101 tests green, lint clean.
