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 3.79 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
6 violating nodes across 6 rules, 130 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 1 node -
critical
image-alt— Images must have alternative text 1 node -
moderate
landmark-banner-is-top-level— Banner landmark should not be contained in another landmark 1 node -
moderate
landmark-no-duplicate-banner— Document should not have more than one banner landmark 1 node -
moderate
landmark-unique— Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node -
serious
link-name— Links must have discernible text 1 node
Accessibility failures 3 of 17 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 1 node -
image-alt— Image elements do not have `[alt]` attributes 1 node -
link-name— Links do not have a discernible name 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
