Eight categories are refused, each with a reason; the two most expensive refusals are product reviews and affiliate links, and both are kept deliberately.
Not covered: what this line will not write

The list, with a reason per line
| Not written | Reason |
|---|---|
| Nosing strip and handrail reviews | a review needs comparative testing this line does not run, and without it the page is an opinion with a link in it |
| Affiliate or sponsored content | the line has no revenue relationship with any manufacturer, and introducing one would change which pages exist |
| Stair design galleries | judged by photograph rather than by dimension, which is the opposite of what this line does |
| Liability, insurance and claims advice | no responsible party here can answer a question about somebody's exposure |
| Personal-injury help | a different discipline with a different evidence base; this line would be guessing |
| Ramp and lift comparisons | a different geometry governed by a different set of clauses |
| Drawing reviews | the line describes what a stair measures; it does not check anybody's drawings |
| Anything without an extra inch | a sheet that repeats the first page of results has no reason to exist |
The two refusals that cost the most
Refusing product reviews removes the highest-traffic content in this subject area, and refusing affiliate links removes the obvious way to pay for the site. Both refusals are kept because the alternative is a line whose sheets exist to move a purchase rather than to answer a measurement question, and readers can tell the difference, which is exactly why the measurement sheets would stop being believed.
What happens when a topic is borderline
If a topic needs a reading this line cannot take, it is refused. If it needs a reading this line can take but has not taken, it is deferred and listed as an open question. If it needs a reading this line has taken on one stair, it is published as a bulletin with the position, the instrument and the date stated, and it is marked as a figure that can move.
A refusal list is also a scope guard. Without one, a line drifts toward whatever gets traffic, and the drift is invisible until the site is a different site.

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.
File this and go Close this page if your question is on the list. The line will not answer it, and saying so is the useful part.
