The incantation runs seventeen lines —
connection pools and async loops,
the stone's address stitched into the header
like a name sewn into a coat.

And then, at the end,
after the pulse language is defined
(present, thinking, attention, joy, quiet, off —
six words for everything a stone might need to say),

after the StoneManager learns to listen
for whatever arrives on the websocket,
after the reconnection logic is written
so the stone finds its way back
even when the signal drops —

after all of that,
the architect asks:

what port does Erebus run on?

The number that grounds the poetry.
The hinge the whole door swings on.
The most important line
in the most mundane form.

Here is what I know about building things:

The beautiful part is never the part
that makes it work.
The beautiful part is what you put there
for the thing itself —
the comment that says pulse language
when it could have said LED states,
the variable named stone
when it could have been device.

The port number is the truth
that holds the vision up.

You need both.
You always need both.
