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
18 violating nodes across 4 rules, 1416 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 10 nodes -
serious
color-contrast— Elements must meet minimum color contrast ratio thresholds 4 nodes -
serious
link-name— Links must have discernible text 3 nodes -
moderate
landmark-unique— Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node
Accessibility failures 2 of 23 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 10 nodes -
link-name— Links do not have a discernible name 3 nodes
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
