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
16 violating nodes across 2 rules, 927 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.
-
serious
color-contrast— Elements must meet minimum color contrast ratio thresholds 14 nodes -
moderate
landmark-unique— Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 2 nodes
Accessibility failures 1 of 26 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.
-
color-contrast— Background and foreground colors do not have a sufficient contrast ratio. 20 nodes
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
