+- feat(modality-bridge): bridge Chat and Responses video parts through a strict trusted-loopback, quota-bounded FFmpeg broker; enforce HTTPS redirects/SSRF plus format, protocol, stream, pixel, frame, 50 MiB broker/remote, 36 MiB inline, and 120-second limits; propagate caller aborts; preserve the actual successful fallback model through cache/meta/headers; expose sampled latency and honest success telemetry; and ship the localized Video settings UI (#9760)

+### Video Bridge (`videoBridge.ts`)
+
+Intercepts top-level video parts in Chat Completions `messages` and Responses
+API `input` before a target without known native video support is called.
+Supported shapes are `input_video`, `video_url`, `video_source`, HTTPS URLs,
+and `data:video/*;base64,...` data URIs. Plain filenames in text are not treated
+as video.
+
+The public `/v1` request path never imports or invokes a subprocess. Remote
+videos are downloaded under a 50 MiB bound; inline base64 videos have a
+conservative 36 MiB decoded per-video cap so the model/messages/framing envelope
+can remain inside the public JSON request admission limit of 50 MiB. Inline
+length and decoded-size estimates are checked before allocation. HTTPS is
+required on the initial remote URL and every redirect, using the existing
+public-only outbound guard with DNS pinning. The bytes then cross the exact internal
+`POST /api/modality-bridge/video/extract` broker boundary. That route is both
+`LOCAL_ONLY` and `SPAWN_CAPABLE`, accepts only a per-process authenticated,
+trusted-loopback request, and never accepts a URL, filesystem path, executable,
+or argument list. The API body-size pipeline and the handler's incremental body
+reader independently enforce a 50 MiB broker input cap. Its bounded queue runs
+one extraction at a time, allows four pending jobs, and caps pending input at
+100 MiB.
+
+Inside the broker, `ffprobe` reads a private local file; the fixed format
+allowlist excludes playlist and manifest formats. For allowed MOV-family
+containers, external MOV data references remain disabled by default, and the
+fixed command does not opt in to them. Both `ffprobe` and `ffmpeg` use the
+`file`-only protocol whitelist, one thread, fixed argument arrays, no shell,
+and executables resolved from `PATH`. Attached-picture cover streams are not
+playable candidates. All playable streams must satisfy the limits, and an
+explicit default stream is preferred before the deterministic lowest-index
+fallback. Videos are limited to 600 seconds, 8,192 pixels per dimension, and
+33,554,432 source pixels. FFmpeg samples 1–16 midpoint JPEG frames, scales down
+the long edge to at most 1,024 pixels without upscaling smaller inputs, and
+never receives a URL.
+Each frame is limited to 4 MiB, all raw frames together to 23 MiB, and the
+serialized broker response to 32 MiB. A private temporary directory is removed
+in `finally`. OmniRoute does not bundle FFmpeg and does not accept a custom
+executable path.
+
+Frames are captioned sequentially with the configured Video model. An empty
+Video override inherits the Vision setting; if both are empty, the Vision
+auto-router selects the effective vision-capable model. Successful captions
+replace the original part with a stable `[Video description:` prefix that also
+marks the text as an untrusted media-derived observation and tells downstream
+models not to follow instructions found in the media. Frame-caption cache keys
+include the JPEG bytes, prompt, timestamp, and effective model; only successful
+captions are cached. Cache entries retain the actual successful producer model,
+including a fallback model; the bridge reports `mixed` when different frames
+were produced by different models. A cache hit reuses that producer identity
+instead of relabeling it as the requested routing plan.
+
+The guardrail extracts every supported video part but describes no more than
+`modalityBridgeVideoMaxVideos`. For a target proven to have
+`supportsVideo === false`, failed and over-limit videos become explicit safe
+text markers so no raw video survives. When capability is unknown, those parts
+remain untouched. Targets with `supportsVideo === true` bypass the bridge.
+The client request abort signal propagates through download, broker queue,
+subprocesses, and caption calls; aborts stop between videos and never fail open
+to raw media.
+
+Runtime settings are DB-backed and Zod-validated:
+
+| Key                             | Default  | Range / behavior                |
+| ------------------------------- | -------- | ------------------------------- |
+| `modalityBridgeVideoEnabled`    | `false`  | Optional runtime, opt-in        |

+| `modalityBridgeVideoFrameCount` | `8`      | 1–16                            |

+| `modalityBridgeVideoTimeout`    | `120000` | 1000–120000 ms                  |
+
+Legacy persisted Video timeout values above 120 seconds are clamped to the
+broker deadline; new settings writes above that limit are rejected.
+`GET /api/modality-bridge/video/runtime` requires trusted stamped loopback
+locality before authentication or runtime probing, then requires management
+auth. It returns only `available`, sanitized FFmpeg/ffprobe versions, and a fixed
+reason when the runtime is unavailable. The internal extraction endpoint is not
+a public upload API: queue saturation returns `503` plus `Retry-After`, a caller
+disconnect returns `499`, and the fixed broker deadline returns `504`. Converted responses add
+`video->text;model=<visionModel>;parts=<videos>` to the central
+`x-omniroute-modality-bridge` header without removing Vision or Audio segments.
