Field sweep additions, all absent from OpenStreetMap and found by the
author on Google Maps:
40.16 滝下八幡神社 栗山町字滝下
43.07 滝下発電所 栗山町字滝下 (北海道企業局)
57.44 登川神社 夕張市楓
66.78 豊進神社 むかわ町穂別稲里
71.86 穂別ダム神社 むかわ町穂別稲里
79.67 福山神社 むかわ町穂別福山
93.58 名石駐車場 占冠村字中央
102.36 日高神社 日高町宮下町
104.52 日高発電所 日高町字千栄 (北海道電力)
106.22 右左府発電所 日高町字日高
Plus 滝ノ上信号場 and 楓信号場, which OSM tags railway=signal /
railway=junction with no place tag, so both fell through every filter.
Corrections: モトツ橋 moved 86.16 → 87.12. It does not cross パンケモトツ沢川;
it is the sheltered span between モトツトンネル and 福山トンネル, roofed by
モトツシェルター — the identical 62 m lengths are the same deck. Author
also fixed 下福山橋 → 77.05 and オロロップ橋 → 77.55, matching route01's order.
Readings: kana is the source of truth. Romaji regenerated from it in
wāpuro style, no macrons. Adds 274-romaji.py, which does that
deterministically and is idempotent against the current table.
Artifact now shows Romaji in the table and kana under each strip mark.
CSV and GeoJSON re-propagated. 168 entries, 118 with readings.

穂別ダム神社 at 71.86 km, 18 m off the road and 166 m before the dam.
Absent from OpenStreetMap entirely — nothing tagged place_of_worship
within 900 m of it — so it came from the author's Google Maps sighting,
positioned from the pin and geocoded to 勇払郡むかわ町穂別稲里.
Readings: author's pass takes kana coverage from 42 to 83 of 173.
Cluster summary regenerated: 穂別 now carries five objects (キャンプ場,
ダム, ダム神社, 大橋, 川).
Page rebuilt, artifact republished, CSV and GeoJSON re-propagated.

滝ノ上信号場 (45.21 km) and 楓信号場 (57.76 km) were both absent. OSM tags
them railway=signal / railway=junction with no place tag, so they fell
through both the railway filter and the place layer that had caught
滝ノ下信号場 and 十三里信号場.
滝ノ上 was a passenger station until its demotion to 信号場 in 2024.
Strip marks now carry the full object name; the km line underneath shows
the extracted Name when it differs. Labelling by the stripped root alone
was ambiguous where several objects share a name.
CSV and GeoJSON re-propagated from the Markdown. 172 entries.

Keeps the interactive map available offline and under version control
while the song is in progress.
- 274-transect.html — self-contained; carries its data in a script block,
fonts from Google Fonts, no other external requests. Opens by double
clicking. Same page as the published artifact.
- 274-route.json, 274-districts.json — the route line and the 23 大字
bands from the 250 m reverse-geocode sweep.
- 274-transect-build.py — re-reads the roster out of 274-dev.md and
rewrites the page's data block in place, leaving markup and script
alone. Run it after editing the table.
Everything under wip/ so the auto-wiki pipeline leaves it alone.
