A port may now declare `image`, `audio` or `video`. Each is the artifact
reference the engine already had, narrowed by the `media_type` on it, so a
speech recogniser declares what it eats rather than taking any bytes at all and
finding out. Bytes still never travel as a message and nothing on the wire
stops being JSON: a camera publishes one reference per frame, a microphone one
per chunk, and a reference may carry a `meta` dict nothing here interprets.
Streaming media is therefore an ordinary streaming port — with one change to
what that means. An emission used to journal an item with no payload, so
downstream read whatever was current when the item was claimed; a consumer
slower than its producer saw only the newest chunk and the ones between were
lost. That is right for a training curve and wrong for a second of speech, so
an emission now journals a `kind="emission"` item carrying its values, and the
executor hands them to the nodes reading that message instead of writing them
to state again. The value in state stays the latest, which is what everything
else reads, and the wave is filtered by what actually changed rather than
walking everything reachable. No queue serialization change — the existing
`outputs` field carries it.
Continuous media makes the store's missing GC a real problem, so this closes
it: `sweep_artifacts` runs hourly, keeps every digest a `run_artifact` row
records or a live message holds, spares anything written in the last hour, and
stands aside entirely while a run is in flight, since a node may store a
checkpoint long before it returns the reference to it. That also collects the
orphans a deleted flow has always left behind. `ARTIFACT_GC_INTERVAL_S=0` turns
it off.
Around the edges: `GET /artifacts/{digest}` serves the media type the caller
passes and answers ranged requests, so a browser plays a clip rather than
downloading it; `PUT` spools to disk instead of holding the whole body in
memory, as does `save_artifact` given a path; a Media widget draws whatever its
message points at, and a wall panel may fetch the bytes its own tiles are
showing and nothing else; and a connector gets `save_artifact`, for a device
whose readings are bytes.
What this cannot do is live video: a frame every second or two is a glance, and
the honest answer above that is the camera's own stream, which the widget takes
as a URL and the browser plays from source.

The JSON preview capped a ScrollArea rather than the pre inside it. Radix
sizes that viewport in percent, which resolves to the content's own height
against a box carrying only a max-height, so a list or dict of any length
spilled out of the node panel and the edge popover and painted over the
sections below.

A record or an artifact reference was serialised into the port row, and the
panel widened until the type selects and the buttons beside them were pushed
off its edge — a checkpoint reference is 130 characters of digest, and none of
them are what you want while wiring a flow. What shows now is what the value
*is*: 'artifact · weights.json · 60B', 'record · 3 fields'. A chevron unfolds
the whole of it, wrapped, inside the panel it belongs to.
A scalar still reads as itself, and scrolls its own overflow into view when it
is longer than the room it was given. That behaviour already existed inside
the edge inspector; it moves to Common/Marquee so the panel can have it too,
and the inspector drops its own copy of the raw-JSON block along with it.
The rows are smaller for it: the type select finally fits the word 'artifact',
and a port nothing has come through on says so with a dash rather than a
sentence — nine ports of 'nothing has come through yet' is a panel of prose
about the absence of values.
The e2e check asserts both halves: that the summary is what appears, and that
the panel is still exactly 400px with the value unfolded.
