Median lithium abundances (〈A(Li)〉) vs. median metallicity (〈[Fe/H]〉) with their respective median errors for all the stellar groups in our sample, stratified by HC groups and Li detection (orange markers indicate detected values, and purple markers indicate upper limits). Left panel: star-shaped markers depict 〈A(Li)〉 vs 〈[Fe/H]〉 for the entire sample, with each marker annotated to indicate the corresponding HC group. Right panel: similar to the left panel, but further stratified by stellar movement. Circle markers represent stars that moved inwards; x-shaped markers indicate stars that moved outwards; and square markers depict stars with a birth radius similar to their current Galactocentric distance (‘Equal’). In cyan, we additionally display the abundances for the Solar photosphere (⊙), meteorites (⨷), the Spite plateau (horizontal dashed line), and a newer SBBN estimate for A(Li) from Pitrou et al. (2021) at 2.7 dex (horizontal dot-dashed line). Note that upper limits do not include error estimations for lithium since no de facto detection was made, as shown in all other plots of the paper.
