Confirmed:
everything from July 21 onward is missing from the index — five-plus meetings including all the recent all-team syncs. They're all committed to git and on disk, but the sync bookmarked them as done without importing them. That's why my query only surfaces stuff up to ~July 16-21 and nothing recent.
The likely culprit is a stuck sync bookmark from those earlier
commit/sync failed
crashes (the 110/git errors)
