274: single-spine route shapes, west and east approach stubs

The route shapes were built by sorting road nodes by distance. Where R274 has a central reservation OSM draws each carriageway as its own way, so the sort alternated between them: 216 of 1,715 points in 274-route.json lay on the second carriageway, up to 38 m sideways, in the divided sections after 福山大橋 and through 占冠. All three shapes are now traced back along the shortest-path tree, so they follow one spine. Point spacing sums to exactly the km span and km strictly increases in every file. No roster coordinate came from a dropped point. 274-route-west.json 54 pts 30.46 - 35.53 ends on the first main point 274-route.json 1499 pts 35.53 - 108.74 274-route-east.json 54 pts 108.56 - 113.99 overlaps main by 0.18 km The stubs let the video bring the road in before 川端橋 and carry it on past 右左府 for 東に続く. The GeoJSON carries all three as separate lines. Page and GeoJSON rebuilt, which also picks up the roster fixes. 274-dev.md brought up to date: file table, current roster figures, and three new entries under errors found and fixed.

+"""Build the lyric index: every sung line resolved to its roster entry and timing.
+
+Reads 274.lrc and 274-lookup.csv and writes 274-lyrics-index.csv, one row per
+resolved object per lyric line, in song order.
+
+    start / stop   the line's own timestamp and the next timestamp in the file,
+                   blank spacer lines included — so every line has a stop.
+    sung           the text exactly as it appears in the lyric
+    object         the roster's full name for it (the power stations carry their
+                   operator prefix there but are sung without it)
+    kind, lat, lon from the roster
+
+Two lines need more than a name lookup:
+
+  * モトツ橋にモトツシェルター is one structure driven through and two facilities
+    in the registers, so it emits TWO rows sharing one timing.
+  * The district headers (勇払郡むかわ町穂別福山 and the rest) are addresses, not
+    points, and three of them repeat because the road re-enters the district —
+    so they cannot resolve by name alone. Each is resolved from the run of
+    objects it introduces: the header takes the first object's coordinates, and
+    km_from / km_to span the run.
+
+    Not from 274-districts.json, which is sampled along the road and therefore
+    cannot describe a district the road does not physically enter. 宮下町 has no
+    band at all, 本町東 exists only as 本町東一丁目, and 千栄's band sits at
+    107.25-107.75 while the station it introduces is at km 104.52, 666 m off the
+    carriageway inside 千栄.

mikkeli	5ca0b871f8	274: single-spine route shapes, west and east approach stubs The route shapes were built by sorting road nodes by distance. Where R274 has a central reservation OSM draws each carriageway as its own way, so the sort alternated between them: 216 of 1,715 points in 274-route.json lay on the second carriageway, up to 38 m sideways, in the divided sections after 福山大橋 and through 占冠. All three shapes are now traced back along the shortest-path tree, so they follow one spine. Point spacing sums to exactly the km span and km strictly increases in every file. No roster coordinate came from a dropped point. 274-route-west.json 54 pts 30.46 - 35.53 ends on the first main point 274-route.json 1499 pts 35.53 - 108.74 274-route-east.json 54 pts 108.56 - 113.99 overlaps main by 0.18 km The stubs let the video bring the road in before 川端橋 and carry it on past 右左府 for 東に続く. The GeoJSON carries all three as separate lines. Page and GeoJSON rebuilt, which also picks up the roster fixes. 274-dev.md brought up to date: file table, current roster figures, and three new entries under errors found and fixed.

mikkeli	7af0f48afe	274: drop 紅葉山橋, fix オロロップ橋 and 下福山橋, re-timed lyric 紅葉山橋 is not on R274. The full Reiwa 8 bridge register lists it once, on 国道452号 (100.1 m, PC, 1989), just up R452 from the 紅葉山交差点. It had come in through the OSM corridor sweep, which selected by distance rather than by road — hence the only `bridge (structure)` kind in the roster and its 533 m offset. An audit of all 53 roster structures against every route in the three registers found no other stray. オロロップ橋 moves to 78.31 km from the author's Google pin, on the 221 m OSM bridge way that matches the register's 205.9 m. 下福山橋 moves to 78.03, the 104 m way. Both had been displaced by using the オロロップ沢川 stream crossing at 77.05 as an anchor; the stream and the bridge are 1.2 km apart. The sung order ペンケ → 下福山 → オロロップ → 福山 was already right. Lyric re-timed by the author with 紅葉山橋 removed; 274.md and 274.lrc match. Lyric index regenerated: 97 lines, 98 rows, zero backward km steps.

mikkeli	e271da634e	274: lyric index for the visualiser Adds 274-lyrics-index.py and its output 274-lyrics-index.csv: every sung line resolved to its roster entry, with coordinates and timing. 98 lyric lines -> 99 rows. Columns are start/stop as mm:ss.xx and as seconds, the line as sung, the roster's full name for it, kind, km, lat/lon, and km_from/km_to for district headers. stop is the next timestamp in the file, spacer lines included, so every line has one. Four aliases cover the gap between sung and registered names: the three power stations are sung without their operator prefix, and モトツ橋にモトツシェルター names two facilities, so it emits two rows sharing one timing and one coordinate. 東に続く is typed as closing, no object. District headers resolve from the run of objects they introduce, not from 274-districts.json. Those bands are sampled along the road and so cannot describe a district the road does not enter: 宮下町 has no band at all, 本町東 exists only as 本町東一丁目, and 千栄's band sits at 107.25-107.75 while the station it introduces is at km 104.52, 666 m off the carriageway inside 千栄. Object names in the roster are unique, so no other disambiguation is needed. The script exits non-zero and names any line it cannot resolve.

mikkeli	c7e24949cc	274: put the lyric back into road order Two places where the sung order did not follow the carriageway. 楓駐車帯 moves up one line, between 千紫橋 and 万紅橋. It sits at km 57.08, between their 56.60 and 57.25 — it was sung after 万紅橋. 穂別長和 splits into two headers around the 稲里 block. The road runs 長和 → 稲里 → 長和, but the two 長和 stretches had been welded into one block sung first, so the 稲里 block then started 10.84 km behind where the previous line left off. Now: 長和 62.36 - 62.94 オマナイ橋, 桂木橋稲里 64.44 - 71.86 大和橋 … 穂別ダム神社長和 72.02 - 75.28 長和トンネル … 稲里トンネル This is the same repeated-header pattern the song already uses for 由仁町川端 / 栗山町滝下 at the opening, where the road crosses back over the 夕張川. Applied to both 274.md and 274.lrc; the two are now identical, 98 lines each. Lyric order is monotonic by kilometre end to end.

mikkeli	3a8d49641a	274: move the song and its working files into wip/274/ Eleven files were cluttering wip/ alongside an unrelated draft. They now sit together in their own directory. Checked against the pipeline in novoyuuparosk-auto-wiki before moving: - discovery is source_dir.rglob("*.md"), so nested directories are found - the skip test is `"wip" in rel.parts`, which still excludes wip/274/ while the song is in progress - relative links resolve as (path.parent / rel_path), i.e. against the file's own directory, so the three docs keep linking to each other - the lrc field resolves as abs_path.parent / lrc_rel, so 274.lrc must and does sit beside 274.md Both scripts locate their inputs from __file__, so they needed no change; verified after the move that --check is clean and the page rebuilds all 132 entries. Non-Markdown files are never read by the pipeline at all.

mikkeli	80e3521f44	274: aligned lrc 115 timestamped lines, 14.54 s to 8:12, monotonic throughout. Resolver check against 274-lookup.csv: of 97 lines carrying text, 75 match an object name exactly and 17 match a full address, leaving 5. Four of those need aliases rather than corrections — the three power stations appear without their operator prefix (川端発電所, 滝の上発電所, 北電日高発電所 against 北海道企業局川端発電所, 北海道企業局　滝の上発電所, 北海道電力日高発電所) and one is the merged モトツ橋にモトツシェルター. The fifth, 東に続く, is closing text and not an object. So the lyric-to-row index needs a four-entry alias table and nothing else.

mikkeli	e45562a9d2	274: two named parking bays; roster trimmed to 132 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. CSV and GeoJSON re-propagated from the Markdown.
