…parser Two root causes behind 16,517 directory size differences (Bug C): 1. IOCP out-of-order I/O: when an extension record is parsed before its base record, the base overwrites first_stream.size with 0 (losing the extension's $DATA size). Now snapshot and restore first_stream.size alongside the other extension-data snapshots. 2. Extension records with only $I30 attributes were silently skipped by the early-return guard (which didn't check dir_index_size). Now include dir_index_size/dir_index_allocated in both the guard and the return value. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
