C2 — real-AE scene snapshots on the node:
- node-agent: runner/snapshot.go RunSnapshot (aerender -comp <key> -s f -e f
→ findRenderedOutput → ffmpeg -frames:v 1 PNG); client ClaimSnapshot /
GetSnapshotUploadURL / ReportSnapshotResult / ReportSnapshotFail; snapshotLoop +
pollSnapshotOnce mirroring the scan loop (reuses the AE-exclusive lock).
- render-svc: GetSnapshotJobMeta + UploadURL handler presigns a PUT to the
public-read user-uploads bucket at snapshots/{project}/{scene}.png and returns a
permanent public_url (not the time-limited export presign); MINIO_UPLOAD_BUCKET +
MINIO_PUBLIC_URL config + compose env + /snapshot/:id/upload-url route.
Epic B — bind edited colours into the render:
- render-svc GetRenderBindings UNIONs studio.saved_shared_colors +
saved_scene_colors (type 'color') so the node writes them before render.
- node-agent binder.go routes type:"color" bindings into the bind-spec colors[]
array that bind.jsx already applies to the frshare colour layers.
