50.52 紅葉山駐車帯 41 m off 夕張市紅葉山
57.08 楓駐車帯 39 m off 夕張市楓
Both signposted and both absent from OpenStreetMap, which carries no
parking or rest-area features anywhere on this stretch. One of them is a
bay the author had previously recorded as unnamed. Responsible body is
北海道開発局 札幌開発建設部 岩見沢道路事務所 by jurisdiction — R274 is
指定区間 全線 and every adjacent structure registers to that office — but
no document names either bay, since parking has no published register.
Author's trimming removed 38 rows: the 丁目 grid, all five bus stops,
川端駅, and some civic furniture. That leaves 132 rows with 132 distinct
object names, so the planned lyric-to-row index is unambiguous with no
special case except モトツ橋/シェルター, which already share coordinates.
274-romaji.py learns ちゅうしゃたい and ていしゃたい so parking bays split
as Momijiyama chuushatai rather than one run-on token; --check is clean.

The file called 274-dev.md was never dev notes — it was the roster. It
now sits alongside 274-lookup.csv and 274-lookup.geojson under the same
stem, since all three carry the same table.
274-dev.md -> 274-lookup.md the roster, source of truth
274-method.md -> 274-dev.md how it was built
References updated: DOC in 274-romaji.py, the roster path in
274-transect-build.py, and the docstrings in both. 274.md now links to
the dev notes and the reference tables separately; each of the two docs
links to the other and back to the song page.
Titles follow: "274 - reference tables" and "274 - how the roster was
built".
Verified after renaming: 274-romaji.py --check reports no changes and
274-transect-build.py rebuilds 168 entries, so neither script lost its
input.

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.
