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.

Roster now carries, for every entry: kana and romaji readings, the
administrative address with its reading, and the 大字 it sits in.
- Kana/Romaji columns prefilled from OSM name:ja-Hira / name:ja-Latn
where they exist (42 of 170); the rest are blank rather than guessed,
pending the plaque readings.
- Address and Address kana for all 170, from 国土地理院 reverse geocoding
joined to GSI muni.js and 日本郵便 郵便番号データ. Confirms 千栄=ちさか
and 穂別長和=ほべつおさわ.
- District transect: the route sampled every 250 m gives 23 大字 bands
with entry and exit kilometres. R274 does not pass through 字ニニウ at
all — it runs 穂別福山 → 字中央 → 字日高, and both municipal boundaries
fall inside tunnels (穂高 and 日高).
- Fixes a real bug: duplicate-named features shared one set of
coordinates, so both セイコーマート pointed at the same spot 50 km
apart. 12 coordinate cells were wrong.
- 沙流川 added at 105.67 km, where the road joins its valley at 右左府,
rather than at its nearest point past the range end.
- Kind labels normalised to English throughout.
CSV and GeoJSON regenerated from the Markdown, which is now the source
of truth. GeoJSON also carries the district bands as geometryless
features.

Follows the pulse / pulse_dev split. 274.md keeps the frontmatter, the
intro and the lyrics workspace; everything below moves to 274-dev.md,
which will document how the PoI candidates were assembled and hold the
filtered charts.
Uses the new relative-Markdown-link convention rather than a siblings
macro, in both directions. Dev page carries publish: false to match
274.md while both are under wip/.
Contents moved verbatim; the dev page's own prose is still to be written.

Replace the 由仁-十勝清水 reference section with the narrowed
川端橋 - 右左府 scope.
- structures table gains a kilometre key, derived two ways: sequence
alignment of the 北海道開発局 register against OSM way geometry by
length, and watercourse crossings as anchors where a bridge is named
after the stream it crosses (草木橋, ポン久留喜橋, オロロップ橋,
モトツ橋, 福山大橋, 新川橋)
- watercourses deduplicated 176 -> 32; the inflation was single rivers
split across many OSM ways
- PoI and watercourse tables sorted on the same datum so all three
interleave by distance
- working language switched to English, Japanese kept for proper nouns
- gloss fixed: 川端 as 'riverside', not 'end of a river'
Distances are measured from a datum near 上野幌 and are not official
kiloposts (official KP is roughly this plus 14 km). Full-route data and
the source registers live in the KB at ~/infra/kb/inbox/surreal/.
