the host from response headers.

What LCP is made of observed, unthrottled
A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.
Measured on the trace before throttling is modelled, so these are real durations that will not sum to the 10.25 s above — that figure is a simulation of the same load on a slow phone and connection. Read these for the proportions: which phase dominates.

Main thread work
Axe violations axe-core 4.13.0, full rule set
17 violating nodes across 3 rules, 1462 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
link-name— Links must have discernible text 8 nodes -
serious
color-contrast— Elements must meet minimum color contrast ratio thresholds 6 nodes -
moderate
heading-order— Heading levels should only increase by one 3 nodes
Accessibility failures 3 of 30 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.
-
link-name— Links do not have a discernible name 8 nodes -
color-contrast— Background and foreground colors do not have a sufficient contrast ratio. 6 nodes -
heading-order— Heading elements are not in a sequentially-descending order 3 nodes
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
