Corgi reduce restarts searches for successive changed identifiers, while lopsided joins build owned needle columns. Share a monotone matching-range iterator that gallops across gaps and borrows the existing identifier slices. State is local to the iterator; sorted unique needles match complete runs in the sorted haystack.
Based directly on master-next after ownership merged as #868. The rebase preserves the complete source tree.
On the measured one-worker Reach and SCC workloads, maintenance time falls by 15.6% and 9.5%, respectively; load time falls by 5.8% and 5.9%. These are medians of four processes on Apple M4, with 1,000 edge replacements per epoch. Runtime changes: +102/-52 lines; tests: +39.
Validation: 131 selected library/integration tests passed again after rebasing; two existing tests ignored. Existing independent graph-oracle checks cover 240 snapshots per normal and instrumented binary
