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.

 # Northwich committee of magic researches songs repository
+
 Just a collection of lyrics of songs. Probably will be managed into proper folders. Probably will have LRCs.
+
+## Publishing to the wiki
+
+Song pages are auto-published to <https://wiki.novoyuuparosk.org> by the
+**songs pipeline** in the companion repo `novoyuuparosk-auto-wiki` (the
+"repo next door"). It triggers on push to `master`.
+
+- **Source-file contract** (frontmatter fields, body conventions): see
+  [`pipelines/songs/SCHEMA.md`](../novoyuuparosk-auto-wiki/pipelines/songs/SCHEMA.md)
+  in `novoyuuparosk-auto-wiki`.
+- **Pipeline overview** (branch convention, triggers, categories, LRC, etc.):
+  [`pipelines/songs/README.md`](../novoyuuparosk-auto-wiki/pipelines/songs/README.md).
+
+In short: a file is published when its frontmatter has `wiki.publish: true`
+and it isn't under `wip/`. The `title` field becomes the wiki page name.
+
+## Linking to another song page
+
+Write an ordinary relative Markdown link. There is nothing to declare in the
+frontmatter:
+
+```markdown
+For more behind-the-scene shenanigans, see [Dev gibberish](pulse_dev.md).
+```
+
+At publish time the `.md` target is swapped for the target file's own `title`,
+giving a proper wikilink — so renaming a page means editing its `title` and
+nothing else. The link keeps working in Gitea's blob view and in any editor
+preview, because it is just a link.
+
+Two things to know:
+
+- The target must be published too (`wiki.publish: true`, outside `wip/`).
+  Linking to a file does **not** publish it; an unresolvable link fails the CI
+  run instead of quietly turning into plain text.
+- Links do not work inside a ` ```columns ` fence — that block is verbatim by
+  design. Put them in ordinary prose.
+
+This replaces the old `wiki.siblings` frontmatter block and its `ALL_CAPS`
+placeholders, which are gone.
+
+## Side-by-side lyrics (columns shorthand)
+
+To lay two (or more) versions of a song next to each other — e.g. an original
+and its translation — use a fenced code block tagged `columns`, with each
+column separated by a line containing only `===`:
+
+````markdown
+```columns
+**原題**
+
+一行目
+二行目
+===
+**Title**
+
+first line
+second line
+```
+````
+
+Notes:
+
+- Line breaks and blank lines are preserved verbatim (each column is rendered
+  with line breaks intact).
+- `N` columns ⇒ `N − 1` `===` separators.
+- Use Markdown emphasis inside the block: `*italic*`, `**bold**`,
+  `***bold-italic***`. (No need for raw HTML.)
+
+This is implemented entirely by the auto-wiki pipeline at publish time; the
+authoritative description lives in
+[`SCHEMA.md`](../novoyuuparosk-auto-wiki/pipelines/songs/SCHEMA.md#columns-side-by-side-shorthand).
+See [`kairo/kimito_en.md`](kairo/kimito_en.md) for a real example.

+**You and me and a gentle journey**
+
+You know there was a dream I had long ago
+Of a somewhere that is far away
+And a journey for the two of us
+An end I am yet to have you see
+
+All of the lost stuff
+Collecting but dust
+Forgotten up there on overhead racks
+
+It’s going to take time
+Until the end and should
+(should) you feel like dreaming
+You’re always welcome on my shoulder
+
+
+
+A voice of comfort 
+A voice of yours
+
+
+
+
+
+
+The scenery a-flowing by
+The swaying train, and this feeling merged and intertwined
+In a stream of journey to which
+For now I shall give myself away
+
+If not with me you abide
+There won’t be not such meaningful events left
+
+
+
+To go across the borderline

+
+任何接收环境的本底噪声，指的是某一频段内任一时刻全部背景信号能量的总和。在城市环境中，其主要来源包括配电设施、无线通信网络以及各类消费电子产品的电磁辐射。本底噪声没有统一来源，也不受集中调度，而是众多独立运行的发射源累积叠加的结果：各发射源均在自身参数范围内工作，叠加之后形成一种持续而大致均匀的背景。通常将这一背景电平视为固定基线，而不作为需要关注的变量。幅度等于或低于该基线的信号，在物理上仍存在于介质之中，但接收系统无法将其同背景区分开来，因而被认为无法恢复。  
+
+冲激信号，又称单位冲激，是指这样一种信号：它在所有时刻的取值均为零，仅在某一瞬间例外；在该瞬间，其取值理论上为无穷大，但总积分面积须恒等于一。实际中，理想的冲激信号无法物理实现，通常以持续时间极短、幅度极高、带宽足够的脉冲来近似。对任一线性时不变系统而言，其冲激响应（即以冲激作为输入时所得到的输出）足以完整描述该系统在此后任意输入下的行为。若没有输入，处于静止的系统不产生输出，也不表现出任何可与其他静止系统相区别的特性。仅凭一个冲激及其测得的响应，即可推导出系统完整的传递函数。

+ある受信環境のノイズフロアとは、ある周波数帯域内の任意の瞬間に存在する背景信号エネルギーの総和をいう。都市環境では、その主要な発生源として、配電設備・無線通信網・各種民生用電子機器からの電磁放射が挙げられる。ノイズフロアには統一された発生源はなく、集中的に制御されているわけでもない。それは、独立して動作する多数の送信源の累積的な出力から生じるものであり、各送信源はそれぞれの諸元の範囲内で動作しながら、合わさることで持続的かつほぼ一様な背景を形成する。通常、この背景レベルは着目すべき変数としてではなく、固定された基準値として扱われる。振幅がこの基準値に等しいか、それを下回る信号は、媒質中に物理的には依然として存在するものの、受信系がそれを背景から区別することはできず、復元不能とみなされる。

+インパルス信号は、単位インパルスとも呼ばれ、次のような信号として定義される。すなわち、ただ一つの瞬間を除くすべての時刻で値が零であり、その一瞬においてのみ値は概念上無限大となるが、全体を積分した面積はつねに一に等しくなければならない。実際には、理想的なインパルス信号を物理的に生成することはできず、持続時間がきわめて短く、振幅がきわめて高く、十分な帯域幅をもつパルスによって近似される。任意の線形時不変システムのインパルス応答（すなわち、インパルスを入力として与えたときに得られる出力）は、その後のいかなる入力に対するそのシステムの挙動をも完全に特徴づける。入力がまったくない場合、静止した系は何も出力せず、ほかのいかなる不活性な系とも区別しうる性質を示さない。ただ一つのインパルスと、その測定された応答とから、システムの完全な伝達関数を導くことができる。

+## Notes about this song
+
+I will be just writing about anything I think of related to this song. At least for the first go. It's not really creative when you set yourself an agenda and duly follow it.  
+
+### Why pulse
+
+Some time after witnessing the rover song go locally viral at the second transparent fes I said to myself there will be a third. Almost immediately after that, I was sure the keyword would be 'pulse'. Then it took me several months to figure out the third recursive acronym composition. Maybe more than several months.  
+The choice in 'pulse' is for a very apparent reason. It's literally the last kairo (original) song. That is, the last song in the last album. I know they had more 2hu released after that but that's a different business, isn't it.  
+It also is a very good word in itself because there is vitality, there is machinery, there is electronics and engineering, all in one package. It's kairo plus Northwich committee of magic researches.  
+
+### Educational rock
+
+It's now a traditional practice to sample random people speaking random stuff in a post-rock / prog rock / chill hip-hop / shoegaze / you name it song. There is a hip-hop remix of Niinistö's new year's day address but I can't really dig it out of the Internet rabbit hole. And to start with literally the first post-rock I ever listened to was the 2hu band 'the distant journey to you' by our Veto guy and there was an excerpt of Kon Satoshi's 'Paprika' in one of the songs.  
+When I really started to shape this song I was listening to way more Snakes Don't Belong In Alaska than I should. Two of their later songs sampled someone presumably giving a lecture or speech or that sort of presentation. I very much liked it as I'm a big podcast person. It's like listening to your podcasts with psychedelica music accompanying.  
+I also have been a firm believer that signal processing is something any music-aware people should have at least a slightest idea about. So here we are. It's only natural to make my own mini lecture about some signal basics and incorporate that audio signal into the song.  
+The other parts of the song are intentionally cryptic, evasive, indirect, fuzzy, ambiguous but the educational bit should be factual enough it can be considered a decent crash course on what it talks about. Aside from being the catalyst for the song's underlying emotional progressions. We'll talk about that later or never.  
+
+
+### Football manager ruined my life and LLM agents severed it into pieces
+
+Back in your 2022s and 2023s, I wasn't aware of Anthropic and ChatGPT was basically chat powered by GPT. But this time I approach my songwriting as a relatively heavy Claude user. I never fully hand the lyric composition to LLM agents or raw LLMs as that's the fun bit, not the chore bit.  
+What I personally do is usually tell the Claude 'hey I'm thinking about something like this' in either the plainest of languages or just a draft verse. 9 out of 10 times its response pisses me off. Which is consistent with the experience when you do these exchanges with any verified decent human counterpart. No disrespect to my verified 'I can talk poetic bullshit with them' friends but that just happens. And it happens for good.  
+You see the key here is I have someone to talk to, 24/7, super fluent in languages I speak or not, only restricted by usage limits. For writing lyrics I never hit the limits, by the way. An adversary is an essential upgrade to a rubber duck as it gives you feedback. LLM at the core means this adversary is complex enough to be considered unpredictable and thus inspiring.  
+Your Claudes and ChatGPTs and maybe Geminis out of the box loves proposing verses after verses which is less helpful. Fortunately, I've tweaked my instances to hold fire and communicate in a more atmospheric way. In a convo I get myself immersed in the atmosphere I initiated and the agent amplified. I guess that's where all the fever dreams root from.  
+
+
+### On professionalism and why I consider myself pro enough even if I have no proper proof
+
+In a way, I think it's probably true that flair and discipline has a dance of balance in many things, and I take music and association football as two seemingly irrelevant examples. Simply because I'm somewhat invested in those two.  
+A classical piece in the broadest sense takes many, many players with their respective instruments. There would be a leader violinist or a pianist or similar role but let's face it, for like 99% of the time, orchestra players don't play flashy solo phrases. I feel it's like how you have no-nonsense centre backs and anchor defensive midfielders like Jordan Rossiter, that in a sense stand out even less than a goalkeeper.  
+Your rock and pop bands of 3, 4, 5 people is something else. Basically everyone needs to be a star. Everyone will have flashy, tricky solo riffs.  
+And don't get me wrong, I by no means am stating that playing simple notes correctly is inferior to smashing an outrageous riff, or that only getting the ball and passing to the nearest full back is inferior to dribbling over 5 defenders and driving home with a full bollocks swing. That is just not true. Doing the less fancy 'basic' but proper and well is just a slightly, or very different dimension of professionalism. I personally very like no-nonsense centre backs because I played as one because I couldn't do fancy stuff on the pitch.  
+I don't think I can do fancy stuff in my FL studio either. The justification around all this equity of professionalism had a big portion of making myself feel less useless when I tried and mostly failed to learn to play the guitar then bass. Today I'm totally ok and free of complexes like that.  
+
+The financial stability is also very real. My plan about music has always been 'find a job so I can play with music' and I've finally done it. I mean I never got anywhere around trying to be self-sustainable with music alone or as the main means, but having that peace of mind of a roof above is certainly helpful even for a hobby. Having music to unleash my creativity buildup when there is any also helps me cope with the 'boring' day job so it's a win-win. Probably.
+
+### Music, bloody hell
+
+I don't think one should be expecting me to elaborate on how delicate my music craftsmanship is after the revelation and identification as a no-nonsense FL Studio user at best of Conference National level. But you see, there are people who watch Conf Nat as devoted as they themselves watch the Prem, or even more. Absolute skill levels are not that much of a matter.  
+
+I opted to go for a classic dual-bass, dual-telecaster setup with various other helper instruments because that's simply my favourite. The second bass actually turned out to be utilised less than I originally planned. The plan was based on how things went in 'rover over virtually eternal roundabouts'.  
+
+Also, the song started as my experiment of a more techno-heavy style. It didn't end well, but the techno leftovers might be (I'm doubtful) spotted around the place.  
+Then I switched to the target of making this one the third piece in the recursive acronym trilogy, so essentially I'm doing humble plagiarism on the previous two songs. 'sauna as universal neural analeptic' and 'rover over virtually eternal roundabouts' if you're wondering (no one asked).  
+Like stated elsewhere the psychedelica influence from SDBIA is faintly visible (audible). I also applied some of the minimalism principles to the guitar lines, they should be perceivably sparser than some contemporaries.  
+
+Drums and percussions have always been my passion but I think I just got too lazy to fine tune every loop pattern. A drum track of eternally-morphing patterns is not realistic in some sense after all.
+
+### Vocal synthesis masterclass
+
+Could be stating the obvious, but I'm much better at English than Japanese. When it comes to songwriting I might even argue English enjoys priority over my first language, which is Chinese. So it's a bit of a hassle when there is no good enough Yukari TTS on the shelf. On a side note, Kotonoha sisters got their official English / Chinese TTS but that's a shambles. To put it mildly.  
+When I discovered GPT-SoVITS which in English is something that allows you to generate many languages in person A's voice and person B's accent (partly), it's only natural that I immediately went for it. It fit like a glove on the foot.  
+You see, the problem with many voice changers, even in the l'époque de l'intelligence artificielle, is that they end up with English (simplified) pronunciations. Some give you RP but that's not what I want either. It's the models that are my problem and I needed something more weird.  
+The goal was to mix rallienglanti, Bristolian, and some Aussie flavour to produce the random and weird English I usually speak. The end product is nowhere near that, but equally far from 'standard' English. Which is very acceptable.  
+Also, this synthesised voice should not be considered truly Yukari in the copyright or trademarks sense. I credited Yukari because I included pieces of Japanese voice made with the authentic A.I.VOICE 2 editor with a valid license. Just saying.  
+
+For the sung parts, Synthesiser V Studio Pro 2 is the weapon of massive destruction of choice as always. The actual labour is rather boring so I'll leave it as 'I mix-matched mostly Spanish and English phonemes'.  
+
+### So what is this song about?
+
+It's all in the title mate.  
+
+Keep reading if you think that alone is not meaningful enough.  
+
+I'm firmly against providing an answer as standard yet very happy to write my personal interpretations.
+On condition that no one promotes the following text as the only valid official explanation to the song, I can give this:
+
+There is atmospheric pressure around every one of us. It is like the environmental noise that suffocates signals without malice. The noise itself also contains various meaningful, info-bearing signals but all piled up together as a big blob of something, apparently less meaningful than any component was. This is the 'latent semantic envelopes' bit.  
+The pulse is an object as well as an action. It's both the signal that gets sent (and drowned, most of the time) and the action of sending such signals. Not to mention it also means one's heart beats which is a necessary condition for that guy to be alive.  
+Pulsing, under 'latent semantic envelopes' or more straightforwardly, under overwhelming noise, is absurd. But if you subscribe to the absurd, it's not really a problem. 
+That's it.  
+
+In more straightforward laymen's language, the song states the fact that those dumb people like me who keeps sending out pulses nobody else cares (or cared by only a significantly minor group) are probably not doing it to get responses or replies. They do it for the sake of it.  
+
+I probably should have required signing an EULA to have access to this.  
+
+### A personal crusade against claims of superhuman frequential cognitive abilities
+
+The decision to use the 192 kbps MP3 as a source of truth, converting from that to nominally WAV and everything else was based on several grounds. But the dominant one is that I never liked high fidelity above a certain threshold of good enough. And that threshold for me is roughly 192 kbps of MP3. Another reason is that I would like even one more person to think outside of the box, into the channels, towards the corner flag, that this is a form of proper, intentional digital lofi rather than lossy media.  
+It's totally fair to consider this shithousery because shithousery is what I see it as. I'm not doing this digital lo-fi for the sake of art, I do this as reactive banter invoked by phonophile nonsense. If 192 kbps MP3 is good enough to me, then it's good enough.  
+I do think at 128 kbps I start to sense that something is missing and more information density would be appreciated. So the personal threshold is there or thereabouts.  
+
+
+### Trivia
+- In case you didn't notice, the title forms a recursive acronym.
+- In case you didn't notice, the final verse is an acrostic of 'pulse'.
+- In case you didn't notice, the last line is a reverse acrostic of 'pulse'.
+- Brave Borderer and Dark Adventurer are RN fast patrol crafts, or in English, torpedo boats. And I believe both are playable in War Thunder which is why I know them.
+- 'Ocean as a desert buries all of its life' is a blatant steal from America's 'A horse with no name'. The original line is 'ocean is a desert with its life underground'.
+- I have to sneak in the exact words 'rover' and 'sauna', sorry. And in case you didn't notice, they are two related songs. 
+- Many of the words could be understood with a leaning towards their optical engineering aspects. That said, I was more on the electronics end of my opto-electronic science and engineering syllabus. 
+- Meta-trivia: this note is plagued by football cliches, and the song has contracted some.

Under standard conditions, this background level is treated as a fixed baseline rather than a variable of interest. Signals whose amplitude falls at or below this baseline remain physically present in the medium but cannot be distinguished from the background by a receiving system, and are not considered recoverable.
 
-An impulse signal, sometimes referred to as a unit impulse, is defined as a signal with zero amplitude at all points except for a single instant, at which point its amplitude approaches infinity while its total energy remains finite. In practical applications, true impulse signals cannot be generated; they are approximated by short-duration waveforms of high amplitude. The impulse response of any linear system - that is, the system's output when presented with an impulse input - fully characterises that system's behaviour. From a single impulse and its response, the complete identity of the system can be derived. This property is considered fundamental to signal analysis.
+An impulse signal, also referred to as a unit impulse, is defined as a signal with zero value at all points in time except a single instant, at which its value is notionally unbounded, subject to the constraint that its total integrated area equals unity. In practice, true impulse signals cannot be physically produced; they are approximated by short-duration, high-amplitude pulses of sufficient bandwidth. The impulse response of any linear time-invariant system — that is, the output produced when an impulse is presented as input — fully characterises that system's behaviour under any subsequent input. In the absence of any input, a system at rest produces no output and exhibits no properties that distinguish it from any other inactive system. From a single impulse and its measured response, the complete transfer function of the system can be derived. This property is considered foundational to systems analysis.

+
+# 274: how the roster was built
+
+This is the provenance document for the 川端橋–右左府 roster and the interactive
+transect page. The roster itself lives in [274 reference tables](274-lookup.md); the song
+page is [274](274.md).
+
+Nothing here is authoritative about the road. It is a record of where each number came
+from, which numbers are derived rather than measured, and which were corrected by hand
+against reality.
+
+## What exists
+
+| File | What it is |
+|---|---|
+| `274-lookup.md` | The roster. 131 entries, 37.27–107.83 km, 20 kinds, 86 distinct names, 91 with readings. Source of truth. |
+| `274-lookup.csv` | The same rows, 16 columns, generated from the Markdown. |
+| `274-lookup.geojson` | The same rows as points, plus the three route lines (`route-west`, `route`, `route-east`) and the district bands. |
+| `274-transect.html` | Self-contained interactive page. Opens from disk; also published as an Artifact. |
+| `274-route.json` | 1,499 route points with their kilometre, one clean spine through the range. |
+| `274-route-west.json` | 54 points, km 30.46–35.53: the road arriving before 川端橋, ending on the first main point. |
+| `274-route-east.json` | 54 points, km 108.56–113.99: the road carrying on past 右左府, for 東に続く. |
+| `274-districts.json` | 23 大字 bands with entry and exit kilometres. |
+| `274-transect-build.py` | Re-reads the roster and rewrites the page's data block. |
+| `274-romaji.py` | Fills the Romaji column from the Kana column. |
+| `274-lyrics-index.py` | Resolves every line of `274.lrc` to its roster entry with timing and coordinates. |
+| `274-lyrics-index.csv` | Its output: one row per sung object, the file the music video syncs to. |
+
+Flow is one-way: **`274-lookup.md` → everything else.** Editing a generated file is pointless;
+it will be overwritten on the next build.
+
+## Scope
+
+The range is **川端橋 (37.27 km) to 右左府 (106.22 km)**, chosen by the author, not derived.
+
+- West end at the bridge rather than the settlement: 川端's substance lies upstream, west
+  of the bridge, and is deliberately outside the frame. The JR station was excluded for
+  the same reason and later re-added.
+- East end at 右左府 — 発電所, 変電所 and the transmission line 右左府線 — after which the
+  road continues east out of the piece.
+- Everything beyond is out of scope: 千呂露橋, 大颱橋, the whole of 日勝峠, the Tokachi
+  descent. Full-route material stays in the KB at `~/infra/kb/inbox/surreal/md/`.
+
+Two entries sit past the nominal east end (滝の沢川 107.29, ルウケシオマナイ川 107.83)
+because they fell inside the computation window; they are not part of the intended range.
+
+## Sources
+
+**北海道開発局 個別施設計画, 令和8年3月** — the national facility registers, three PDFs:
+橋梁長寿命化修繕計画, 道路トンネル個別施設計画, 大型の構造物個別施設計画. Gives every bridge,
+tunnel and shed with length, width, type, build year, inspection year and 判定区分. No
+coordinates and no kilometrage. Text extracted with pypdf; columns reconstructed by
+anchoring on the inspection year and grade at the right and the bureau/office at the left.
+**Not checked against the original page images.**
+
+**OpenStreetMap** (ODbL, retrieved 2026-09-08/09) — the route geometry, and most points of
+interest. Route relation `r6651380`. Reading tags `name:ja-Hira` and `name:ja-Latn` where
+they exist, which was 42 of the original 170 rows.
+
+**国土数値情報 河川データセット (W05)** via the Geoshape repository at 国立情報学研究所 —
+watercourse names and geometry for the 石狩川, 鵡川 and 沙流川 systems. All 561 named rivers
+were fetched, not only the 「その他」 group: named rivers carry their own 河川コード and are
+served separately, which is the mistake that caused the first pass to miss 夕張川, 鵡川,
+沙流川, 穂別川, サヌシュッペ川, both ウシャップ rivers and ホルカクルキ川.
+
+**国土地理院 逆ジオコーディング** — `mreversegeocoder.gsi.go.jp`. Coordinate to municipality
+code and 大字. Joined to GSI's `muni.js` for the municipality name including the 郡.
+
+**日本郵便 郵便番号データ** (Hokkaido file, CP932) — kana readings for municipality and
+町域, folded from half-width katakana to hiragana.
+
+**route01.com r274p2–p4** and **hgf03030.a.la9.jp** — two drivers' 2019 trip reports. The
+only source for structure *order*, which the registers do not carry. Also the source for
+several details no dataset has: the painted-out hexagon on the 道道610 sign, the bear
+statue at the drive-in, the 合目 markers restarting on the Shimizu side.
+
+**Google Maps** — via the author, for everything OSM lacks. See below.
+
+## Method
+
+**Kilometre datum.** A node graph is built from the ways of the OSM route relation.
+Dijkstra from a seed node gives distance along the road for every node. The relation is
+broken across the divided-carriageway stretch in 札幌, so the seed is the west end of the
+largest connected component, near 上野幌 — **not the official start**. Comparison against
+KP values in a 帯広開発建設部 disaster report suggests official KP ≈ these figures + 14 km,
+unverified. One kilopost read on Street View would settle it. Everything downstream —
+ordering, district bands, offsets — is internally consistent regardless.
+
+**Point features** are projected to their nearest route node; the offset column is the
+straight-line distance from feature to road.
+
+**Structures** have no coordinates in the registers, so their positions are derived two
+ways. First, OSM tags each bridge and tunnel as its own way, giving a position and a
+geometric length; aligning that ordered sequence against the registers' ordered lengths by
+Needleman–Wunsch transfers the positions. 穂高トンネル lands within 9 m. Second, where a
+bridge is named after the watercourse it crosses, the geometric crossing point gives an
+independent position that overrides the alignment — this fixed 草木橋, ポン久留喜橋,
+福山大橋 and 新川橋. It misled twice: モトツ橋 and オロロップ橋 are both named for streams they
+do not cross at the bridge (see below).
+
+The alignment is reliable in the 60–97 km core, where tunnels anchor it, and unreliable at
+both ends where small bridges cluster and OSM ways do not correspond one-to-one. 唐沢橋
+(9.1 m) and 福本沢川橋 (3.0 m) have no position at all — below the size OSM splits out.
+
+**Watercourses** are positioned at closest approach, which equals the crossing for streams
+the road crosses and is arbitrary for streams it runs beside. サヌシュッペ川 is tangent at
+two reaches 5 km apart for this reason; 沙流川 is placed where the road joins its valley
+at 右左府, not at its nearest point, which falls past the range end.
+
+**District bands** come from reverse-geocoding the road itself every 250 m — 287 samples
+producing 23 bands with entry and exit kilometres. This is the only method here that can
+say where the road enters and leaves a district; point data cannot, because representative
+points sit at settlement centres.
+
+**Name extraction** strips generic tails (橋, 川, トンネル, 覆道, 郵便局, 発電所, 町, 丁目),
+strips the Ainu qualifiers パンケ/ペンケ/ポン, and aliases variants together (十三哩→十三里,
+滝ノ上→滝の上, 浪ノ沢→浪の沢, 能見→熊見, クルキ→久留喜). Mechanical and meant to be corrected.
+
+**Romaji** is generated from kana, never from kanji, in wāpuro style — おう→ou, ゅう→yuu,
+っ doubles, ー repeats, ん→n' before a vowel or y. The trailing generic is split off and
+lowercased. Kana is the source of truth; where kana is blank, romaji stays blank.
+
+## Human in the loop
+
+The machine-derived roster was wrong in ways no amount of cross-referencing would have
+caught. Every item below came from the author reading signs, satellite imagery and Street
+View, or from knowledge not in any dataset.
+
+**Corrections to derived data**
+
+- **十三哩橋 / 十三里橋** — the register writes 哩, the kanji for *mile*; the plate on the
+  bridge reads 里. Confirmed on Street View. As a place name it is read **とみさと**. The
+  origin is the 13-mile post from 追分駅, so the name runs mile → ri → hamlet, and the
+  register is the only place the mile survives.
+- **ホルカクルキ川** — I claimed it had no counterpart in W05. It does, 河川コード
+  8101030169; I had fetched only 12 of 561 named rivers. The 北海道 plate on the bank
+  confirms the spelling and gives the Ainu original **ホロカ・クルヒ (horka・kurihi)**,
+  "to turn back" and "its shadow" — *horka* marks a stream running counter to its parent.
+  route01's ホロカクルキ is a slip.
+- **モトツ橋** — I had it at 86.16 km on the パンケモトツ沢川 crossing. It is at 87.12,
+  the sheltered span between モトツトンネル and 福山トンネル. The identical 62 m lengths of
+  bridge and shelter are the same deck, not a coincidence. Street View and satellite,
+  July 2025: the two tunnels now read as continuous.
+- **オロロップ橋 and 下福山橋** — I anchored オロロップ橋 on the オロロップ沢川 crossing at
+  77.05 km, but the stream crossing and the bridge are 1.2 km apart. An interim swap then
+  put 下福山橋 on that wrong spot. The author's Google pin places オロロップ橋 at 78.31, on
+  the 221 m OSM bridge way that matches the register's 205.9 m; 下福山橋 is the 104 m way
+  at 78.03. The original length-alignment had both right, and the sung order
+  ペンケ → 下福山 → オロロップ → 福山 was correct throughout.
+- **紅葉山橋** — flagged by the author as the only `bridge (structure)` in the roster, with
+  a 533 m offset. The full Reiwa 8 bridge register lists it exactly once, on **国道452号**
+  (100.1 m, PC, 1989), just up R452 from the 紅葉山交差点. Removed.
+- **滝ノ上信号場** — demoted from passenger station in 2024. Not in any dataset consulted.
+- **登川** — the active community now falls under 楓 jurisdiction; 登川 is largely the
+  administrative remnant of Yubari's first settlements. This explains why 登川神社, 登川橋
+  and 登川郵便局 all geocode to 夕張市楓 while the district called 登川 begins further east.
+- **穂別ダム神社** belongs to 穂別長和 — the dam and reservoir are in that district and only
+  the shrine fell the wrong side of an old boundary. **稲里神社**, the proper shrine for
+  穂別稲里, is too far inland to reach from R274. Neither fact is derivable from the
+  geocoded address, which reports only where each thing physically sits.
+
+**Found by hand, absent from OpenStreetMap**
+
+滝下八幡神社 · 滝下発電所 · 登川神社 · 豊進神社 · 穂別ダム神社 · 福山神社 · 名石駐車場 ·
+日高神社 · 日高発電所 · 右左府発電所
+
+Ten entries, all located from Google Maps pins resolved to coordinates, then positioned
+against the route and geocoded like any other row. OSM carried two of the eight shrines.
+A shrine 18 m from the carriageway (穂別ダム神社) was missing, so the shrine count is a
+floor rather than a total, and parking and rest areas are effectively unmapped along the
+whole route — 名石駐車場 came through only because it has a Google place listing.
+
+**Judgement calls**
+
+Readings were filled by hand and are not all guaranteed; the plaques will settle the
+doubtful ones. Rivers are being skipped. Shops, restaurants, bus stops, temples, fuel
+stations, campsites and hotels were removed deliberately. 名称不明, ベリベツ川 and
+デチン沢川 were excluded with reasons recorded. A vacant Seicomart was rejected as an entry
+and read instead as a relocation to the shop 859 m away.
+
+## Errors found and fixed
+
+Recorded because they indicate where this kind of pipeline fails.
+
+- **Duplicate-named features shared one set of coordinates.** A name-keyed lookup meant
+  both セイコーマート pointed at the same spot 50 km apart; likewise three ENEOS and paired
+  bus stops. 12 coordinate cells were wrong.
+- **穂高トンネル is 1,991 m long and was built in 1991.** The parser took the first
+  year-shaped token and grabbed the length. Fixed by anchoring build year and age from the
+  row end. The only such collision on the route.
+- **W05 coverage** — see ホルカクルキ川 above. Assuming the 「その他」 group was the whole
+  dataset produced a confident false negative.
+- **Over-stripping** — 登川 reduced to 登, and のぼりかわ romanised as "Nobori kawa", because
+  a trailing 川 looks generic. Both are toponyms where it is integral.
+- **A table column mismatch** in the page: a header change applied while its matching cell
+  insert silently did not, shifting every column right of Kana by one.
+- **A join key type mismatch** left the 大字 column empty in a committed CSV.
+- **The corridor sweep selected by distance, not by road.** Anything within 2 km of R274 was
+  admitted, which is how 紅葉山橋 on R452 got in. An audit of all 53 roster structures
+  against every route in the three registers found no other stray.
+- **Route shapes zig-zagged.** They were built by sorting road nodes by distance, and where
+  R274 has a central reservation OSM draws each carriageway as a separate way, so the sort
+  alternated between them. 216 of 1,715 main points 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, which follows one spine; point spacing sums to the
+  km span and km strictly increases. No roster coordinate came from a dropped point.
+
+## Limits
+
+- Distances are **not official kiloposts**.
+- Structure positions are derived, not surveyed. Two have none at all.
+- Register figures are not checked against the original page images.
+- Shrine and parking coverage is a floor, not a total.
+- The roster records where each object physically sits. It cannot express which community
+  an object belongs to — that distinction lives in the prose.
+- The underlying 全国道路施設点検データベース restricts commercial use and copying of the
+  dataset. Facility names and build years are facts; wholesale redistribution of the tables
+  is not.

+# 274: reference tables
+
+The roster of named objects along the 川端橋–右左府 stretch, and the notes that go with it.
+For how it was built, see [274 development notes](274-dev.md); for the song page, see [274](274.md).
+
+## Scope: 川端橋 → 右左府
+
+West end **川端橋**, on the 夕張川, where 夕張市 / 由仁町 / 栗山町 very nearly meet.
+East end **右左府** — 変電所, 発電所, and the transmission line 右左府線, all carrying
+the name of a municipality dissolved in 1943. After that the road goes on east.
+
+Everything past 右左府 — 千呂露橋, 大颱橋, the whole of 日勝峠 and the Tokachi descent —
+is out of scope. Full-route material lives in the KB:
+`~/infra/kb/inbox/surreal/md/` — `R8kobetsu-shisetsu-R274.md` (national registers,
+all 268 R274 facilities), `R274-chimei-junjo.md` (place names), `R274-enkatsu-shisetsu.md`
+(facilities), `R274-PoI-kawabata-usappu.md` (this scope, finer).
+
+Distances below are OSM-derived, measured from a datum near 上野幌, **not official KP**
+(official ≈ +14 km, unverified). Structures have no distance — order only, from route01.
+
+### Master table
+
+Every named entry in the range, in road order. **Name** is a first-pass extraction of the
+proper noun — generic tails stripped (橋, 川, トンネル, 覆道, 郵便局, 発電所, 町, 丁目 …),
+Ainu size/position qualifiers stripped (パンケ, ペンケ, ポン), and a few variants aliased
+together (十三哩 → 十三里, 滝ノ上 → 滝の上, 浪ノ沢 → 浪の沢, 能見 → 熊見, クルキ → 久留喜).
+**Object** keeps the full name as recorded. Correct the Name column freely; it is a
+starting point, not an authority.
+
+131 entries, 86 distinct names. The clusters — where one name spreads across several
+objects — are where the road's naming actually shows:
+

+|---|--:|---|

+| 穂別 | 5 | 穂別キャンプ場 · 穂別ダム · 穂別ダム神社 · 穂別大橋 · 穂別川 |
+| 日高 | 5 | 北海道電力 日高発電所 · 日高 · 日高トンネル · 日高神社 · 日高郵便局 |

+| 稲里 | 3 | 稲里トンネル · 稲里橋 · 稲里簡易郵便局 |
+| モトツ | 3 | モトツシェルター · モトツトンネル · モトツ橋 |
+
+Coordinates are WGS84. Structure coordinates are taken from the route line at the
+structure's kilometre, so they sit on the road rather than on the structure's own
+centroid; watercourse coordinates are the crossing point; PoI coordinates are the
+feature's own. Machine-readable copies: `274-lookup.csv`, `274-lookup.geojson`.

+### Things worth keeping in the text
+
+- **紅楓橋 1958** is the oldest structure in scope, and the furthest-upstream crossing
+  of the 夕張川. **唐沢橋 2004** is the newest.
+- Eight bridges date from **1988**, three tunnels from **1991** — the new-built
+  紅葉山–穂高 section going in. That section had no predecessor road at all.
+- **穂高トンネル is 1,991 m long and was built in 1991.** The two numbers are identical
+  and the national register's own column order makes them easy to confuse.
+- **モトツ橋 (62 m, 1988) and モトツシェルター (62 m, 1990) are one structure** — a
+  sheltered bridge spanning the gap between モトツトンネル and 福山トンネル, the deck built
+  first and roofed two years later. Identical lengths because they are the same span.
+  Confirmed on Street View and satellite imagery, July 2025: the two tunnels now read as
+  continuous. Both remain separately listed and separately inspected in the registers.
+  *(superseded note: same length, same name,
+  two years apart.)*
+- **福山第1ゲート 79.81 km, 福山第2ゲート 79.86 km** — the closure gates, 50 m apart.
+- **21 km of nothing** between 穂別福山 (80.01) and 日高 (100.90): no named facility,
+  no PoI, no settlement within 2 km. That is ニニウ and the 樹海.
+- The 滝下/滝の上 cluster carries the の/ノ split: 滝の上発電所 and 滝の上公園 against
+  滝ノ上神社 and the district 滝ノ上. The register writes 滝の上こ線橋.
+- **十三哩橋** in the register, **十三里橋** on the sign, **とみさと** on the map.
+  13 miles from 追分, via 里, into a hamlet name.
+- 夕張市街 is **17 km** from 紅葉山交差点. That is how far the road misses the town by.
+- JR石勝線 runs alongside here under **many スノーシェッド**. R274 has none.
+- 道道1065号夕張厚真線 is severed at the 夕張/厚真 boundary and the plan to finish it
+  has been cancelled.
+- Overhead at 紅葉山: **夕張のぞみ橋, 夕張きぼう橋, 夕張みらい橋** — three E38 bridges
+  named Hope, Wish and Future crossing a road whose own bridges carry river names.
+
+### Flags
+
+- 右左府発電所 is not in OpenStreetMap; only 右左府変電所 and the line 右左府線.
+  Coordinates need manual confirmation.
+- 交差点 names have no open database — OSM has 7 named nodes on all 388 km. Junction
+  names in scope come from ja.wikipedia and route01 only.
+- 唐沢橋 and 福本沢川橋 are in 日高町 but their position relative to 右左府 is unconfirmed.
+- Distances are not official KP. One kilopost read on Street View would fix the offset.
+- A 史跡 at 103.41 km appears in OSM with the name `79616` — an import artefact, not a name.

+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.

+Kana is the source of truth. Romaji is generated wāpuro-style — no macrons,

+consonant, ー repeats the preceding vowel, ん→n' before a vowel or y.
+
+The trailing generic is split off and lowercased (Kawabata hashi, Houshin jinja,

- 
-For things that are not easily pronounced (e.g. formulae, expressions, symbols), inclusive either:  
-- Mark how the thing should be pronounced in a pair of adjacent parentheses

-- (inclusive) Or don't embed these elements too deep into the flow of sentences; use common, laymen's language instead

-The general direction is to stay boring, but the deadpan kind of boring. Keep technical language appearing but explain things in more laymen's language.

-A boring lecture about signals and systems, and its digital implementation in DSP.  
-Borderline 'song' less 'poetic'.  
-
-The actual material (text that is read) is in Japanese.  
-
-## Outline
-
-### 1. Signals and systems
-- What is a signal
-  - A function of one or more variables carrying information; here, amplitude over time
-- What is a system
-  - A system maps an input signal to an output signal
-  - Characterized entirely by its behavior on inputs — the internals are not required
-- Most systems are nonlinear — linearity is a special property, not the default
-  - Linearity: superposition holds — scaling and additivity
-  - Most physical systems violate this under sufficient conditions (e.g. overdrive: linear below clip threshold, nonlinear at and above it)
-- Time-invariance
-  - A time-invariant system responds identically regardless of when the input arrives
-  - Violation: any system with time-varying parameters (e.g. modulated effects)
-- LTI as the restricted, studied case
-  - Satisfies both simultaneously — analytically tractable
-  - A deliberate simplification; not a description of typical reality
-- The impulse signal; impulse response
-  - The impulse: unit energy concentrated at a single point in time
-  - The impulse response: what an LTI system outputs when fed an impulse
-  - Completely characterizes the system
-  - The impulse response is a function — it exists in the same space as signals; systems are absorbed into signal space
-
-### 2. LTI and convolution
-- An LTI system is fully characterized by its impulse response
-  - Any input decomposes into scaled, shifted impulses
-  - By linearity and time-invariance, the output is the corresponding sum of scaled, shifted impulse responses
-- Convolution as the operation
-  - That sum is convolution: y = x * h
-  - Symmetric in its arguments: x * h = h * x
-  - Signal and system are interchangeable operands — both are functions; convolution makes no distinction between them
-- Commutativity: for LTI systems, order of composition is irrelevant
-  - Two LTI systems in series have a combined impulse response equal to the convolution of each
-  - h₁ * h₂ = h₂ * h₁ — order does not affect the result
-
-### 3. Signal transformation
-- A signal in time can be equivalently represented in the frequency domain
-- The Fourier transform: s(t) ↔ S(ω); decomposes a signal into its constituent frequencies
-- Analog signals carry frequency components from DC to arbitrarily high frequencies
-
-### 4. Filters
-- A filter is an LTI system — characterized by its frequency response H(ω)
-  - H(ω) is the Fourier transform of the impulse response h(t)
-  - Filtering: shaping a signal's spectrum by selectively attenuating or preserving frequency bands
-- Basic types: lowpass, highpass, bandpass
-  - Lowpass: passes low frequencies, attenuates high
-  - Highpass: passes high frequencies, attenuates low
-  - Bandpass: passes a target band, attenuates above and below
-- In discrete time: finite impulse response (FIR) and infinite impulse response (IIR) filters
-
-### 5. Discrete time
-- Discretization on two axes: amplitude and time
-  - Amplitude: bit depth; finite resolution; hard clip at boundary (unlike analog soft limits)
-- A signal's frequency spectrum, not its time-domain values alone, determines what is lost in sampling
-  - Analog signals have components from DC to infinite frequency — not representable in discrete time
-  - Discrete time is viable if components up to a sufficient frequency are preserved
-- Nyquist: given sampling rate Fs, faithful reconstruction is guaranteed up to Fs/2
-  - What Fs/2 should be is an applied engineering question — Nyquist does not answer it
-  - Components above Fs/2 are lost: aliasing
-- LTI and convolution hold in discrete time — commutativity survives
-
-### 6. Nonlinearity and consequences
-- Real systems violate LTI: time-varying parameters, feedback, saturation
-  - Each breaks a different condition: time-variance breaks TI, feedback and saturation break linearity
-  - Examples
-    - Modulated delay (chorus, flanger): delay time varies with time → time-invariance breaks; same input at different times yields different output
-    - Overdrive: saturation above threshold → linearity breaks; EQ before overdrive ≠ overdrive before EQ
-- Commutativity breaks — order of composition is no longer irrelevant
-  - h₁ followed by h₂ ≠ h₂ followed by h₁ in general
-  - No universal rule; behavior must be examined per case
-

-
-信号とシステム、そしてデジタル信号処理について説明する。
-
-### 1. 信号とシステム
-
-まず信号とは何か、次にシステムとは何かを定義し、
-その上でシステムの性質を議論する。
-
-信号とは、一つ以上の変数の関数として定義される。
-信号は情報を担う。
-ここでは時間を変数とし、振幅の時間変化として扱う。
-
-システムとは、入力信号を出力信号へ写す操作である。
-内部の構造は定義に含まれない。
-システムはその入出力の関係によってのみ特徴づけられる。
-
-システムの性質として、まず線形性を取り上げる。
-線形システムとは、重ね合わせの原理が成立するシステムである。
-入力をスケーリングすれば出力も同率でスケーリングされ、
-入力の和に対する出力は、各入力の出力の和に等しい。
-
-ここで注意が必要である。
-多くの物理システムはこの条件を満たさない。
-線形性は特殊な性質であり、デフォルトではない。
-
-次に時不変性について述べる。
-時不変システムとは、入力を時間軸上でシフトしたとき、
-出力も同じだけシフトされるシステムである。
-パラメータが時間とともに変化するシステムは、時不変ではない。
-
-線形かつ時不変なシステムを、線形時不変システムと呼ぶ。
-以降の議論はこの線形時不変システムを対象とする。
-これは解析的に扱いやすい、制限された特殊ケースである。
-現実の典型ではない、という点は記憶にとどめておいてほしい。
-
-線形時不変システムの性質をさらに掘り下げる前に、
-インパルス信号を導入する。
-インパルス信号とは、単一の時刻に単位エネルギーが集中した信号である。
-線形時不変システムにインパルスを入力したときの出力を、インパルス応答と呼ぶ。
-このインパルス応答が、線形時不変システムを完全に特徴づける。
-
-ここで重要な点を強調する。
-インパルス応答は、信号と同種の関数である。
-これにより、システムは信号と同じ操作の空間に置かれる。
-システムと信号の区別は、操作の上では消える。
-
-### 2. 線形時不変システムと畳み込み
-
-なぜそう言えるのか。
-任意の入力信号は、スケーリングされた時間シフトインパルスの和として分解できる。
-線形性と時不変性により、
-それぞれのインパルスに対する出力の和が、入力全体に対する出力となる。
-この操作を畳み込みと呼ぶ。
-
-y = x * h　（y イコール x 畳み込み h）
-
-畳み込みはその引数に対して対称である。
-x * h = h * x　（x 畳み込み h イコール h 畳み込み x）
-これは代数的な性質にとどまらない。x と h が同種の対象であることの表れである。
-
-この対称性から、重要な結論が導かれる。
-二つの線形時不変システムを直列に接続する場合を考える。
-合成されたシステムのインパルス応答は、各インパルス応答の畳み込みに等しい。
-h₁ * h₂ = h₂ * h₁　（h1 畳み込み h2 イコール h2 畳み込み h1）
-接続の順序は、結果に影響しない。
-
-### 3. 信号変換
-
-ここで話題を変える。
-これまでの議論は連続時間を前提としていた。
-しかしデジタルシステムにおいては、連続信号をそのまま扱うことができない。
-
-離散化は二つの軸で生じる。振幅軸と時間軸である。
-振幅軸の離散化はビット深度によって規定される。
-表現可能な範囲の境界でハードクリップが発生する。
-アナログシステムの物理的な限界とは異なり、これは硬い境界である。
-
-時間軸の離散化を理解するには、まず別の観点から信号を見る必要がある。
-信号 s(t)（エス ティー）は、時間領域での表現とは別に、周波数領域でも表現できる。
-これをフーリエ変換と呼ぶ。s(t)（エス ティー）と S(ω)（エス オメガ）は同じ信号の二つの見方である。
-この変換により、信号を周波数成分の重ね合わせとして捉えることができる。
-
-アナログ信号は、原理的にはゼロから無限大まで、すべての周波数成分を持ちうる。
-離散システムはこれを完全には表現できない。
-しかし、もし十分な高周波成分が不要であれば、離散時間は有効な選択肢となる。
-これが離散化の根拠である。
-
-### 4. フィルタ
-
-フィルタは、線形時不変システムの具体的な例である。
-フィルタは周波数応答 H(ω)（エイチ オメガ）によって特徴づけられる。
-周波数応答はインパルス応答のフーリエ変換である。
-フィルタリングとは、信号の周波数成分を選択的に通過させ、あるいは減衰させることである。
-
-基本的な分類としてローパス、ハイパス、バンドパスがある。
-ローパスフィルタは低周波成分を通過させ、高周波成分を減衰させる。
-ハイパスフィルタはその逆で、高周波成分を通過させ、低周波成分を減衰させる。
-バンドパスフィルタは特定の帯域のみを通過させ、それより低い成分も高い成分も減衰させる。
-
-離散時間においては、有限インパルス応答フィルタと無限インパルス応答フィルタの区別がある。
-前者はインパルス応答が有限、後者は無限である。
-
-### 5. 離散時間
-
-サンプリング周波数を Fs とする。
-ナイキストの定理が保証するのは、Fs/2（サンプリング周波数の半分）までの帯域を忠実に再構成できる、ということである。
-それが全てである。定理はそれ以上のことを言わない。
-Fs/2（サンプリング周波数の半分）をどこに設定すべきかは、定理が答える問いではない。それは用途が決める。
-Fs/2（サンプリング周波数の半分）を超える成分は再構成できない。これをエイリアシングと呼ぶ。
-
-重要なのは、この離散化によって線形時不変システムの性質が失われるわけではない、という点である。
-離散時間の線形時不変システムは、連続時間の線形時不変システムと類似した性質を持つ。
-畳み込みは有限または無限の和となる。
-可換性を含む全ての性質は引き継がれる。
-
-### 6. 非線形性とその影響
-
-では、現実のシステムに戻る。
-先ほど線形時不変システムは特殊ケースであると述べた。
-現実のシステムは線形時不変システムの条件を様々な形で破る。
-時変パラメータは時不変性を破る。
-フィードバックと飽和は線形性を破る。
-
-例を挙げる。
-モジュレーテッドディレイを考える。コーラスやフランジャーがその例である。
-ディレイタイムが時間とともに変化するとき、同じ入力でも入力するタイミングによって出力が異なる。
-これは時不変性の破れである。
-
-次にオーバードライブを考える。
-入力が閾値を超えると飽和が生じ、出力は入力に比例しなくなる。
-これは線形性の破れである。
-そして順序が問題になる。EQの後にオーバードライブを適用した結果と、オーバードライブの後にEQを適用した結果は、一般に異なる。
-
-このとき、畳み込みの可換性は成立しない。
-非線形システムでは、一般に
-h₁（システム1）の後にh₂（システム2）を適用した結果と、
-h₂（システム2）の後にh₁（システム1）を適用した結果は、等しくない。
-
-普遍的な規則は存在しない。
-各ケースを個別に検討する必要がある。
