Evidence

23 attacks written before any change on 2026-11-02, run once against engine 1.0.0.

Run	Engine	Held	Note
1	1.0.0	16/23	the reported blind result
2	1.1.0	23/23	after the fixes; the erasure case was given its own marker (run 1 reused one shared by other recordings). The 1.0.0 engine was re-checked with a unique marker separately: it left the text in the -wal file, so the run 1 failure was real.

Run 1, every row (engine 1.0.0)
