This line is written with machine assistance and verified by script and by document; it names no human author because there is none, and it invents no credentials.
The desk: who keeps this line and how a sheet is made
checked 2026-09-16kept by The Nosing Line (a named line, not a person)
What this line is
A working line about stair safety numbers: what the documents print, what a tape reads, and where the two disagree. It is written with machine assistance and checked against the documents it cites. It is not a consultancy, a testing house, or a person with a reputation to protect. The responsible party is the line, and that is what every sheet says.
Where the model is used and where a person is
| Step | Done by | Evidence |
|---|---|---|
| Choosing what the line covers | Model, from the domain and the refusal list | the not-covered page |
| Drafting a sheet | Model | the four tests below |
| Checking every figure against its document | Model, with the document open | each source names the sentence it supports |
| Verifying that links resolve | Script, by HTTP status | every outbound link is checked before publishing |
| Deciding a sheet is finished | Script, against the sheet checklist | the audit report |
No sheet claims a site visit, a laboratory, or a named author. There is no byline because there is no person to name, and inventing one would be the single worst thing this site could do.
The four tests every sheet has to pass
- Swap test: replace the domain's nouns with another domain's nouns. If the sentences still work, the sheet is generic and gets rewritten.
- Strip test: remove every adjective and adverb. Nouns, dimensions, clause numbers and dates must remain.
- Take-away test: hand the table, the flight sheet or the worked example to someone who works on stairs. It must be usable with no surrounding prose.
- Refute test: the sheet must contain at least one sentence a practitioner could disagree with. A sheet of correct generalities fails.
How corrections are handled
A correction is a change to a figure, a unit or a claim, plus a line saying what changed and on what basis. The sheet's check date moves; the URL does not. Rewording a definition to look fresher is not a correction and is not done here.

Each line points at one specific document, with its own title as the link text. No line is a home page and no line is a search result.
