Two defects found by the MMX6/Tomba2 pre-merge regression gate: 1. An ABI bump (v9->v10) invalidated every cached DLL, and the lazy path migrated them PER-DISPATCH (LoadLibrary -> reject -> DeleteFile -> retry) on the emulation thread that owns the window pump — a large cache presented as a "(Not Responding)" black window for minutes. Now a one-time preflight sweep at cache-scan enumerates the DIRECTORY, checks overlay_abi per DLL, purges mismatches (DLL + .ranges + index entry) in one pass, and writes a .abi_<tag>.ok marker so healthy caches skip the sweep on later boots. The per-load ABI gate stays as defense in depth. 2. CACHE_IDX_CAP was 256 and overflow was SILENT — Tomba2's 399-DLL cache truncated, leaving ~140 real DLLs invisible (their regions interpreted forever, no diagnostic). Cap raised to 4096 with a loud never-again loader_log on overflow. Negative-tested: planted a v6 DLL under a valid name — swept on boot along with 25 latent v9 orphans the lazy path had never touched; marker written; game boots to title. Sweep enumerates the directory rather than the index precisely because the index is capacity-bounded (bug 2 hid the plant on the first test iteration).
