Yeah, fixed. July 24/27/28 syncs are now indexed and queryable — confirmed by reading the 07-28 sync content directly. Ingest was writing files fine but sync silently skipped them; forced reimport (157 pages, 235 chunks) cleared it.
Still open (not touching without your go-ahead): the ingest script silently advances its bookmark on failure, and there are duplicate case-collision pages. Want me to draft fixes?
