table verification now runs fully in live diagnostics, with work caps only as a runaway guard. - Per-column row index (string/bool keys, numeric segment tree) of live rows for unreachable checks and compression - Witness-first reachability before computing covers; lazy borrowed coverers - Divide-and-conquer missing cases over column partitions - Allocation-free set intersection/subset checks and in-place merges for string cells - Findings cache keyed by table content, so unchanged tables are not re-verified - Identical cells type-checked once per column;

before the next snapshot the engine walks dependents with a frozen copy of every recorded view (each dependent on the graph stack) and stamps affected documents with a sequence. Consumers read them via changes_since(cursor), so queries in between cannot absorb a change.
