📝 WalkthroughWalkthroughThis change adds OpenRouter, Ollama Cloud, and custom OpenAI-compatible providers. It adds image and video generation with caching, cancellation, specialist models, media UI, HTML artifact previews, and stricter Electron navigation controls. ChangesProvider and media platform
Client provider and media flows
HTML artifacts and desktop policies
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR adds cancellable media generation and bounded caching, but the current implementation can still expose API secrets, terminate the server on persistence or media-stream failures, accept malformed media-provider settings, and consume excessive memory for large videos. It is not merge-ready until these high-impact issues are fixed. Possibly related PRs

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
The 512 MB video read buffers the whole file in memory twice.
readResponseBytes keeps every chunk, then allocates one contiguous Uint8Array of the same total size. A 512 MB video therefore needs about 1 GB of resident memory before the cache write starts. Concurrent video runs multiply that. Lower the video limit to a value the server can hold, or extend the media cache contract to accept a stream so bytes go straight to disk.
♻️ Interim mitigation

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Handle read-stream errors on GET /api/media/:id.
createReadStream(media.path, { start, end }).pipe(res) attaches no error listener. mediaCache.resolve already opened and closed the file, so the open here is a second, later attempt. If the file disappears or a read fails between the two operations, the stream emits error with no listener and Node raises an uncaught exception, which terminates the server. pipe also does not destroy the source when the client aborts the response, so a cancelled video seek leaks a file descriptor.
Use stream.pipeline so both directions are cleaned up.

+ const source = createReadStream(media.path, { start, end });

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Validate specialists before you persist it.
The loop copies body.specialists verbatim into the bot record. The comment below the loop states that fields which decide what runs are type-checked instead of copied through. specialists now decides which provider instance and model run a media turn: startTurn reads bot.specialists?.[mediaTask] and passes specialist.model straight to instance.generateMedia. A malformed body such as {"specialists":{"video":{"instanceId":1,"model":{}}}} is stored, survives restart, and then reaches the driver.
Check the shape in the same way as autoApprove and alwaysAllow.

Guard the timer callback and run.done against throwing callbacks.
onPatch and onDone perform store writes in server/index.ts (lines 475-518), and those writes touch the filesystem. Two failure paths follow from that:
- The
setTimeoutcallback at Line 55 callsinput.onPatchandinput.onDoneoutside anytry. A throw there becomes an uncaught exception and terminates the process. run.doneis never awaited.server/index.tsignores the value returned bymediaRuns.start. IfonPatchin the success path (Line 76) oronDoneinfinishthrows, the async IIFE rejects and Node reports an unhandled rejection, which terminates the process by default.
Wrap the callback invocations so a persistence failure cannot kill the server.

Redact secrets passed through argv.
Line 46 passes argv to redact as an array. Line 28 then calls redact(item) without an argument key. An argument such as --api-key=secret reaches Line 39 unchanged and is written to FAKE_ACP_DUMP.
Apply argument-aware redaction before serializing argv. Handle both --api-key=secret and --api-key secret forms.

Keep Escape scoped to the media viewer.
When an artifact preview is open, this listener and ArtifactPanel both process Escape. One Escape closes the media viewer and the artifact preview. Register this handler in the capture phase and stop propagation for Escape.

Copy specialist selections when duplicating a bot.
The duplicate request copies modelSelection but omits source.specialists in StoreProvider at lines 904-920. A duplicated bot therefore loses its image and video specialist configuration.
Add specialists: source.specialists to the duplicate PATCH payload.

What changed
AbortController, terminalized timeouts/cancellation immediately, and ignored late provider completion.Why
The original media prototype could remain busy after a failed video request, had no dependable cancellation boundary, and allowed late work to overwrite terminal state. Remote URL ingestion also left SSRF edge cases, including IPv4-mapped IPv6 forms. This slice makes the lifecycle explicit and keeps provider data inside constrained response and cache boundaries.

Checklist

Provider/model-specific 9:16 video output may still need request-shape tuning and live-provider validation. Aspect-ratio intent is forwarded, and progress, Stop, cancellation, recovery, caching, and playback are covered here.
