+
+A reusable probe for one audio or video artifact. It reads the file's technical facts
+with the Media Probe node and projects them into a stable, small shape with a mapping,
+so downstream nodes depend on fixed field names rather than the raw probe layout. Use it
+for clip durations, QA measurements, or upload verification. Import it independently, or
+publish it as a composite.
+
+The graph needs a worker with the `media-worker` capability. It makes no network
+requests, needs no credentials, and has no side effects. Media Probe runs with a
+15-second timeout.
+
+## Data flow
+
+1. **Probe media** (`n_media_probe`) inspects the `artifact` input and emits the raw probe
+   information.
+2. **Normalize facts** (`n_map_fields`) copies fields from the raw information into the
+   shape given by `mapping`.
+
+## Inputs and outputs
+
+| Input | Type | Meaning |
+| --- | --- | --- |
+| `artifact` | `artifact` | Required audio or video file, for example an uploaded asset |
+| `mapping` | `json` | Optional map from output field names to probe field names |
+
+| Output | Type | Meaning |
+| --- | --- | --- |
+| `facts` | `json` | The projected facts |
+| `raw` | `json` | The unmodified probe information |
+
+The default mapping carries `duration_seconds`, `width`, `height`, `fps`, and `has_audio`
+across under the same names. That is a guess at the probe's key layout. Run the graph
+once, compare `raw` with `facts`, and adjust `mapping` if a field comes back empty.
+
+## Authentication and security
+
+There is nothing to wire. The graph holds no credentials and calls no service. Probe
+output can include file metadata such as titles and encoder tags, so treat `raw` as
+untrusted input when it is displayed or passed to another service.
+
+## Recommended panels
+
+Use a JSON Inspector for `facts` and `raw`, and Activity or Logs to see worker errors.
+
+## Using it as a composite
+
+Publish the graph and call it from a parent that produces or receives an `artifact`, such
+as a render step or an upload. Connect `facts` to checks like a duration limit, and keep
+`raw` for diagnostics.
+
+## Validation status
+
+The graph passes the repository validator and the node-catalog check against the production catalog, and the Subfork server-side validate endpoint (`POST /graphs/validate`) accepted it on 2026-11-05. It has not been executed on a media worker, so the default
+mapping is unconfirmed, and whether the account plan includes the `media-worker` capability has not
+been verified.
+
+No Subfork platform version could be found on the public API or site, so this note records the check date and the node catalog instead: on 2026-11-05 the catalog served 75 node types, and every node in this graph is version `1.0.0`.
