LINE

This is a shipped standalone native-serve surface: direct sends are implemented, the signed webhook reply loop is implemented, and the runtime stays on channels serve line instead of gateway run today.

Gateway And Ownership

This surface ships a real built-in serve loop, but it remains a standalone native-serve lane today. Use channels serve line directly; it does not join gateway run or the gateway-owned reply-loop contract yet.

​
Operator Notes

  • channels serve line requires --bind because the local listener address stays an explicit operator decision.
  • --path is optional when the default webhook path already matches the LINE console setup.
  • Treat this as a native serve lane, not as an outbound-only sink.
  • Continue to Channel Guides for the full shipped channel matrix.
  • Continue to Channels for the conceptual surface model.
  • Continue to Channel Setup for the shared public setup contract.
