dedup note: Planned 2026-10-10 topic `git-maintenance-commit-graph` passed a strict 186-post inventory and current-source scan. ../git-sparse-checkout/ reduces a monorepo working tree, while ../git-rerere/ stores reusable conflict resolutions and only briefly discusses its own cache cleanup. No existing post covers git maintenance, commit-graph, multi-pack-index, scheduled repository upkeep, or before/after performance measurement. This focused follow-up stays on object-database maintenance, safe scheduling, verification, and rollback-friendly cleanup.
source check: Reviewed against the current official Git maintenance, commit-graph, multi-pack-index, count-objects, gc, and Trace2 documentation on 2026-10-10. Commands were checked with Apple Git 2.50.1; examples favor `git maintenance` tasks and explicitly avoid unsafe concurrent pruning.
