Providers, media, artifacts, and generations
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔴 Critical · up to The current head is not merge-ready: duplicate declarations reportedly break TypeScript parsing, while media generation can poll forever, crash on read errors, or block the server during large writes; the viewer also has a focus-restoration regression. These build, availability, and correctness risks should be fixed before merge. Possibly related PRs

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Remove the abort listener when the pause completes.
abortablePause adds an abort listener on every call and never removes it on the resolve path. generateVideo calls it once per poll iteration with the same long-lived request.signal, so listeners accumulate for the whole run. A long video job leaves hundreds of dead listeners attached and triggers MaxListenersExceededWarning.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Bound the video polling loop with a deadline.
The loop has no attempt cap and no overall deadline. If the provider reports a status that is neither terminal-failure nor terminal-success (for example a job stuck in queued), the driver polls forever and the media run never settles. interval also accepts 0, which turns the loop into a delay-free request loop against the provider.
Add a wall-clock deadline, and keep a small floor on the interval when a caller passes 0 outside tests.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Handle read-stream errors and client aborts on the media response.
The stream has no error handler. If the read fails after the headers are written, for example when the cached object is removed between resolve() and the read, Node emits an unhandled error event and the server process exits. pipe also does not destroy the source when the client aborts, so an interrupted video download leaks the file descriptor.
Attach teardown on both sides, or use pipeline.

Do not block the event loop while writing cached media.
writeFileSync holds the single-threaded server for the full payload. The default video limit is 512 MiB, so one large generated video stalls every other HTTP request, the SSE keepalive, and the screen poller until the write finishes. store is already async, so an awaited write is a drop-in change.

Split the focus setup from the key handler.
The effect depends on onClose. Both call sites pass an inline arrow: src/components/GenerationsPage.tsx line 177 and line 144 in this file. The identity changes on every parent render, so the effect re-runs while the viewer stays open. Two failures follow:
returnFocus.currentis reassigned to the element that is currently focused inside the dialog. After close, focus does not return to the control that opened the viewer.dialogRef.current?.querySelector("button")?.focus()runs again and moves focus from the video controls back to the close button.
Keep the focus capture and restore in a mount-only effect. Read onClose from a ref in the key handler.
🛠️ Proposed fix
export function MediaViewer({ output, onClose }: { output: MediaOutput; onClose: () => void }) {
const dialogRef = useRef<HTMLDivElement>(null);
const returnFocus = useRef<HTMLElement | null>(null);

+ closeRef.current = onClose;

returnFocus.current = document.activeElement as HTMLElement | null;

Name each model picker for assistive technology.
The row labels are plain <span> elements. They are not linked to the picker buttons. A screen reader announces only the selected model or the placeholder, so the three pickers are indistinguishable. Add an accessible name per role.
