zit frames streams a WHOLE store: 507 MB peak on sqlite, more on tcl. quarry ran one ingest goroutine per repository with nothing between them, so a cold start — or a mirror round landing artifacts in several big stores at once — ran that many censuses simultaneously and the memory added. Observed as zit spiking to gigabytes after pulling sqlite and tcl together.

--ingest-limit (default 3) puts them in a work lane. The queue is generous and ingest is never shed: dropping a round would leave an index behind its store until the next poll, trading a correctness surprise for a saving the limit already delivers. check-in: e6fd32e82e user: dmestas tags: trunk
