Video link check
On 2026-09-23, every YouTube link in videos/ was checked against YouTube’s public oEmbed
endpoint, which reports whether a video or playlist exists and may be embedded, and returns its real title. This page
records what that check found, for maintainers and for anyone picking up the
video library track.
Method. A link whose YouTube title shared at least half its meaningful words with the entry’s title was accepted; the rest were compared by hand. This is a title check only, and it will go stale as videos come and go — re-run it before relying on it.

What the check found, and what happened to it
| Result | Unique links | Entries | Action taken |
|---|---|---|---|
| Available and matched the entry | — | 261 | Kept, and embedded on the Part pages |
| Available, but embedding disabled by the uploader | 2 | 2 | Kept as a plain link |
| Available, but a different video from the one the entry described | — | 55 | Removed from videos/ on 2026-09-23 |
| Not found (removed, private, or a wrong ID) | 36 | 38 | Removed from videos/ on 2026-09-23 |
93 entries were removed in total. Four chapters lost their only video and now carry a short “Note:” line instead, in the style already used elsewhere in these files for chapters with no direct links: 2.8, 3.1A, 6.2B, and 3.6 (which had ten entries, all ten of them wrong).
Archive: removed entries
Kept for context — if you are curating new videos for one of these chapters, these are the ones that did not hold up, so you can avoid proposing the same link again.
