docs(35): import lex-fridman-podcast S01E491 OpenClaw to stock Jellyfin Podcasts

Episode resolved as Type=Episode under correct Series + Season but JF
MovieResolver did not parse SxxEyy from filename — ParentIndexNumber and
IndexNumber were null. Series-level + item-level full refresh did not fix.
Required manual API override (PUT IndexNumber=491, ParentIndexNumber=1,
LockData=true).

All 5 prior LFP episodes already have LockData=true — this appears to be
the established pattern for new Lex Fridman Podcast episodes. Generalise
into playbook §1c after one more confirmation.

+
+Single-episode YouTube import into the **STOCK** Jellyfin at `tv.s8n.ru`
+(container `jellyfin-stock`), **Podcasts** library
+(`collectionType=tvshows`, internet providers disabled).
+
+Extends the existing `Lex Fridman Podcast` Season 01 series — sparse numbering
+already in use (400 / 461 / 478 / 479 / 481). Adds episode 491.
+
+## Provenance
+
+- **Source:** YouTube — `https://www.youtube.com/watch?v=YFjfBk8HI5o`
+- **Channel / Series:** Lex Fridman Podcast
+- **Episode:** #491 "OpenClaw: The Viral AI Agent that Broke the Internet — Peter Steinberger"
+- **Tool:** `yt-dlp` on onyx
+- **Format selector:** `bv*[height<=1080][ext=mp4]+ba[ext=m4a]/b[height<=1080][ext=mp4]/bv*[height<=1080]+ba/b[height<=1080]/b` → `--merge-output-format mp4` (source native 1080p)
+- **Subs:** `--write-subs --sub-langs 'en' --embed-subs --convert-subs srt` — user-uploaded English subs embedded AND sidecar `.en.srt`
+- **Thumbnail:** `--write-thumbnail --convert-thumbnails jpg` → sidecar `.jpg`, Primary via Local Posters
+- **yt-dlp output template:** `-o "Lex Fridman Podcast - S01E491 - OpenClaw - The Viral AI Agent that Broke the Internet - Peter Steinberger.%(ext)s"` (downloaded straight to canonical filename — no post-download rename needed)
+- **Staging path on onyx:** `/home/admin/staging-jelly/Lex Fridman Podcast/Season 01/`
+
+### Filename normalisation
+
+Raw YouTube title:
+> `OpenClaw: The Viral AI Agent that Broke the Internet - Peter Steinberger | Lex Fridman Podcast #491`

+- Pipe `|` not present in episode-title portion after suffix drop.
+
+Final filename (per playbook §1c numbered-podcast pattern):
+`Lex Fridman Podcast - S01E491 - OpenClaw - The Viral AI Agent that Broke the Internet - Peter Steinberger.mp4`

+sidecar. 3:15:52 runtime, ~715 MiB — well under the 1080p cap budget for

+
+## Subtitle status
+
+- Embedded: yes — one English `mov_text` track from `--embed-subs`.
+- External sidecar: yes — `.en.srt`.
+- Action: none. WhisperX rebuild not required (channel-published subs trusted

+  auto-CC is rejected — these are author-provided).
+
+## Verification checks
+
+- [x] Folder/filename canonical (`Lex Fridman Podcast - S01E491 - <Title>.mp4` per playbook §1c).
+- [x] No forbidden chars in path.
+- [x] Permissions `user:user` 644.
+- [x] `Scan Media Library` triggered, `State=Idle`, episode appeared in
+      `/Shows/<id>/Episodes?Season=1`.
+- [x] `/Items?searchTerm=OpenClaw` returns the expected single Episode item.
+- [x] `ImageTags.Primary` present (Local Posters from sidecar `.jpg`).
+- [x] `Type=Episode`, `SeriesId` / `SeasonId` correctly attached.
+- [x] `ParentIndexNumber=1`, `IndexNumber=491` populated (see Notes — required
+      manual override, JF scan did not parse SxxEyy from filename despite
+      the filename containing `S01E491`).
+- [x] `LockData=true` set so future series refresh cannot revert the SE.
+- [ ] Direct-play in mobile / Smart-TV client not exercised.
+
+## Notes / surprises
+
+### JF MovieResolver did not parse `S01E491` from filename — manual SE override required
+
+After the `Scan Media Library` pass, the episode resolved as `Type=Episode`
+attached to the correct Series + Season, but `ParentIndexNumber` and
+`IndexNumber` were both `null`. The other 5 episodes in Season 01 (E400 /
+E461 / E478 / E479 / E481) all have the same `Lex Fridman Podcast - S<NN>E<NN>
+- <Title>.mp4` pattern and parsed correctly — root cause unclear.
+
+Tried fixes that did **not** work:
+1. Series-level `POST /Items/<seriesId>/Refresh?MetadataRefreshMode=FullRefresh&Recursive=true` → state did not change.
+2. Item-level `POST /Items/<episodeId>/Refresh?MetadataRefreshMode=FullRefresh&ReplaceAllMetadata=true` → state did not change.
+
+Working fix — direct API override:
+
+```bash
+EP_ID=fbeeffb256a04f103987f9b22d0bd442
+curl -sf -H "X-Emby-Token: $TOK" \
+  "$SERVER_URL/Users/$USER_ID/Items/$EP_ID" \
+  | jq '.ParentIndexNumber = 1 | .IndexNumber = 491 | .LockData = true' \
+  | curl -sf -X POST -H "X-Emby-Token: $TOK" -H 'Content-Type: application/json' \
+      --data @- "$SERVER_URL/Items/$EP_ID"   # → HTTP 204
+```
+
+Inspecting the 5 known-good episodes, **all of them** already have
+`LockData=true`, so this is the established pattern for the `Lex Fridman
+Podcast` series — every new episode appears to need the override. Generalise
+to a post-import step in the playbook §1c "numbered podcast" section.
+
+Possible upstream cause: episode-resolver in JF 10.11.8 may bail when the
+filename contains additional hyphen-separated segments that resemble more
+SxxEyy tokens. Investigate after second occurrence.
