Lighthouse follows the redirect, so the numbers below describe the destination page, not this one. Not yet confirmed as a move; it needs to lead to the same place on several consecutive runs first.
Stack
Detected on the same page load as the accessibility pass — the generator
from <meta name="generator"> or the shape of the page,
the host from response headers.

What LCP is made of
A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Main thread work
Axe violations axe-core 4.13.0, full rule set
3 violating nodes across 1 rule, 1019 passing. This is a standalone axe run, stricter than the subset Lighthouse folds into its score above — and it is the second tiebreaker in the ranking.
-
moderate
heading-order— Heading levels should only increase by one 3 nodes
Accessibility failures 2 of 28 audits
Tracked as a count, not just the score — the weighted score is coarse enough that you can ship a broken component and barely move it.
-
heading-order— Heading elements are not in a sequentially-descending order 3 nodes -
target-size— Touch targets do not have sufficient size or spacing. 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
