feat(grunt/tui): in-process wake listener — rip out daemon#7
Merged
Conversation
The daemon + auto-attach architecture was a workaround for stock opencode's
non-wakeable TUI. With this patch the TUI worker itself binds an HTTP
listener on a pre-picked free localhost port, exposing the same
/session/<id>/prompt_async endpoint used by 'opencode serve' but
in-process. Wake POSTs land directly in the same process that owns the
session, so rendering Just Works (no SSE relay, no attach client, no
display bug).
Concretely:
- New pickFreePort() helper picks a free port via node:net before spawning
the worker.
- Worker spawn env gets OPENCODE_WAKE_PORT + OPENCODE_SERVER_URL stamped
in so MCP children inherit them via sanitizedProcessEnv (hivemind-mcp
auto-announce reads OPENCODE_WAKE_PORT to register peers as wakeable).
- Right after worker boot, TUI calls client.call('server', {port, host})
which makes Server.listen() bind. Existing 'external' path (server, port
flag) is preserved as before.
- Escape hatch: OPENCODE_DISABLE_WAKE_LISTENER=1 skips the bind (legacy
non-wakeable mode, same as upstream).
Drops auto-serve.ts (the daemon-discovery module). The daemon mode is
gone. Closes anomalyco#224 follow-up.

Replaces the daemon + auto-attach dance (v1.15.10-grunt.2/.3) with an in-process HTTP wake listener bound by the TUI worker itself. Wakes land in the same process that owns the session — no SSE relay, no render bug.
Deletes auto-serve.ts. Closes anomalyco#224 follow-up.
