Building the transect visualisation (Song274Transect) is what exposed problems
in the lyric and its index: syncing nodes to the lyric showed 紅葉山橋 lighting
up although it is not on this road (it is on R452), 下福山橋 and オロロップ橋
sitting at the wrong km, and lines timed against the wrong stretch. They were
fixed upstream in the wiki (ncmr-songs 7af0f48, "274: drop 紅葉山橋, fix
オロロップ橋 and 下福山橋, re-timed lyric"), and the lyric deliverables here
follow.
274.lrc — byte-identical copy of the wiki LRC at 7af0f48: 紅葉山橋 removed;
紅楓橋 through 楓信号場 re-timed (1:35.24–1:55.54) with 夕張市楓 at 1:45.77;
登川トンネル at 2:05.23 and its section end at 2:06.62; 稲里トンネル's section
end at 4:25.27. 下福山橋 and オロロップ橋 keep their timing; their km were
corrected in the roster and index.
274.srt — regenerated with scripts/lrc2srt.py, 116 cues.
274.ass — events follow the LRC: district headers as transparent_title spanning
their section, 東に続く as transparent_lyrics_jp, spacers as empty events, the
final line held 5 s. The Aegisub header and all 17 styles are untouched.
117 events -> 116.
route/ — copied from novoyuuparosk-wiki/ncmr-songs wip/274, where it is
generated; read-only here, and its README says so. src/song-274/data.ts loads
274-route.json, 274-lookup.csv and 274-lyrics-index.csv, plus the two approach
stubs: 274-route-west.json (always drawn as covered) and 274-route-east.json
(painted after 東に続く). Also carries the district bands, the GeoJSON and the
reference page. The route shapes are single clean polylines: no
second-carriageway points in the divided sections, km strictly increasing.
Verified: all 116 ASS events and SRT cues match the LRC's order, text and
timestamps; every sung node in the index joins to the roster at matching km.

Text-based deliverables for the 274 video, synced to the lyrics source of
truth in the wiki repo (ncmr-songs wip/274/274.lrc at c7e2494, "put the lyric
back into road order").
- 274.lrc: byte-identical copy of the wiki LRC.
- 274.srt: generated from it with scripts/lrc2srt.py (117 cues).
- 274.ass: hand-styled in Aegisub; every event re-timed to the LRC, with each
address shown from its own timestamp until its section's last place ends.
- BOM.md: untracked assets with BLAKE2b hashes — release audio
274_release1.wav, the white background plate, and the Noto Serif JP
Medium/SemiBold fonts the ASS uses.
Verified: all 117 ASS events and SRT cues match the LRC's order, text and
timestamps.
