Research direction

Reproduce the summary screen with Lighthouse runs whose performance scores are low, then trace how those scores are aggregated and represented. Check the precision handling in that aggregation path and verify that the summary reports the actual nonzero value rather than 0. Done means low scores remain accurate in the summary without changing valid higher scores.

Description

awaiting response prio:medium

When lighthouse performance scores for a run are low enough, when aggregated for the summary screen they are reported as 0, presumably due to an issue with precision.
