The model saw edit_video and export_video with artifact_id next to
generate_image, generate_video, edit_image and transcribe with artifactId,
sourceArtifactId and negativePrompt. Mixed conventions in one tool list invite
wrong calls, so all media inputs now use snake_case like continue_after and the
other builtin tools: artifact_id, source_artifact_id, negative_prompt,
duration_seconds. Handlers, artifact checks, the media card's transcribe
action and the tests follow. Nothing has shipped, so stored job inputs need no
migration.

A card that only says "Transcript" does not tell two transcriptions apart,
and it is English whatever the user's language.
- transcribe takes an optional title like the video operations, so a bot
names the card in the user's language; "Transcript" stays the default.
- Transcribe on a media card passes the source file name as the title.
- The E2E seeds the card through bootstrap as well as threads/get, since the
bot thread's first snapshot arrives with bootstrap.

The card's follow-ups now reach the media job RPCs, and it only offers what
the space can run.
- media.capabilities answers which operations the actor's space can run
(booleans only). The card asks once per minute per space, and only when it
shows finished video or audio, so other cards cost nothing.
- Export and Transcribe call media.jobs.start with the card's message, so the
same bot posts the new card; Cancel calls media.jobs.cancel. A refused
start shows the server's message under the card.
- New files use top-level import type.

The media card's download link uses artifactUrl's download option so a video
or audio output is saved rather than opened inline, and the E2E seeds the
thread snapshot with fresh response headers so the patched body is read.

Media jobs report progress and results through the media block, which the
web app did not render.
- MediaCard renders the block: operation icon, title, status (reusing the
task card's labels, plus "Waiting for GPU" for jobs queued behind the
GPU), a progress bar while active, the error when failed, and outputs:
images as thumbnails with the existing lightbox, video and audio in the
media player, subtitle and text files as file cards. Finished video and
audio get a download link, "Export" with presets labelled by aspect ratio
(the video's own shape left out) and "Transcribe", offered only when the
space can run them; running jobs get "Cancel".
- MessageView renders it with one branch.
- An E2E seeds the card on a thread snapshot with real uploaded artifacts.
- artifact-url.ts and MediaPlayer.tsx are minimal stand-ins for the
pipeline workstream's files and give way to them on merge.
