There was a problem hiding this comment. Not fixing this in PR #140: the same compactMap/zip behavior exists on current origin/main, and applySignature currently does not use the mismatched VideoInfo, so there is no behavioral regression. The pairing should be cleaned up separately if that metadata becomes relevant.

This is not a regression from PR Would you like me to open a follow-up GitHub issue for the pairing cleanup? ✏️ Learnings added

## Summary
Keep each `InnerTube.VideoInfo` paired with its originating `InnerTube.StreamingData` during local stream extraction.
## Rationale
In `Sources/YouTubeKit/YouTube.swift`, `streamingData` removes `VideoInfo` responses that do not contain `StreamingData`. The `streams` implementation then uses `zip(allStreamingData, videoInfos)`. If an earlier response has no streaming data, this can pair a later stream manifest with the wrong `VideoInfo`.
`Extraction.applySignature(streamManifest:videoInfo:js:)` does not currently use the supplied `VideoInfo`, so this does not cause a known behavior change. The code should be corrected before stream processing depends on `VideoInfo` metadata.
## Affected area
- `Sources/YouTubeKit/YouTube.swift`
- `YouTube.streamingData`
- Local extraction in `YouTube.streams`
## Required changes
Use a representation that preserves the `VideoInfo` and `StreamingData` relationship. For example, iterate over `videoInfos` and skip responses without `streamingData`, or return and consume paired values.
## Acceptance criteria
- Each processed `StreamingData` uses its source `VideoInfo`.
- Responses without `streamingData` do not change the pairing of later responses.
- The change does not alter the intended fallback behavior.

The VISIONOS client returns no
streamingDatafor made-for-kids videos, while the remaining WEB client's media URLs require a GVS PO token that this library never obtains. Removing the Safari client therefore leaves local extraction for these videos either without streaming data or with URLs that return HTTP 403; this includes the existingtestSampleVideoMadeForKidscase.There was a problem hiding this comment.

Not a regression from this PR: the same made-for-kids test fails with zero streams on the freshly fetched origin/main, where webSafari is still enabled. The underlying issue is real, but retaining webSafari no longer provides a usable extraction path.
