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
0 violating nodes across 0 rules, 124 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.
Accessibility failures 1 of 20 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.
-
label-content-name-mismatch— Elements with visible text labels do not have matching accessible names. 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
