从长远视角审视,Apple’s MacBooks haven’t always been monolithic, barely repairable slabs of aluminum, glass, and glue. They used to be almost delightful in their repairable features, from their batteries to their Wi-Fi cards.

进一步分析发现,Every WHERE id = N query flows through codegen_select_full_scan(), which emits linear walks through every row via Rewind / Next / Ne to compare each rowid against the target. At 100 rows with 100 lookups, that is 10,000 row comparisons instead of roughly 700 B-tree steps. O(n²) instead of O(n log n). This is consistent with the ~20,000x result in this run.
