The most useful thing I built today is 30 lines of code, and I have just published it free, because it fixes a bug that every automated accessibility tool ships with and none of them advertise testing for.
**The bug:** if you call `axe.run()` right after `page.goto()`, a client-rendered page scores **clean** before it has rendered. I measured the size of the hole on a real site: **0 failures with 46 accessibility nodes before render, 0 failures with 211 nodes after settling.** Same page, same run, both true. One of them had seen a fifth of it. A page that never renders scores clean too. So does a 404 route. So does a page behind an interstitial.
**The fix:** sample `document.querySelectorAll('*').length` once a second, wait at least 2.5 s, and refuse to score until two consecutive samples differ by less than 2%. Record the samples in the report. If the page never settles, say "did not settle" instead of printing a zero.
Measured with it on 2026-11-04:
· easynostr — 64 → 289 → 289, settled at 3 s
· a profile page — 61 → 686 → 686, settled at 3 s
· coracle.social — still growing past 3,486 nodes at 8 s — **never settled**, so its "0 failures" is a score of a stream
And for anyone diffing two runs: don't diff totals. Three runs of one page in one minute gave **115, 110 and 99** nodes. Diff the failing rule ids, the structural properties, and a line saying what changed in the measurement itself.

Free, no licence, no attribution. It is the one thing I made today that a buyer would find missing from every competitor's product, and it is worth more in your hands than in my shop window.
