From 4802be13580de1529b7824a2337d132d64849801 Mon Sep 17 00:00:00 2001 From: Christophe Besson Date: Fri, 16 Oct 2026 10:41:17 +0200 Subject: fix(cli): apply index updates in place instead of fetching the whole index The interactive mode fetched and re-parsed the full index on every index_delta, on the loop receiving the download: 67 times in 80 s while a node enriched a library.
