Independently reproduced across all 33 paks: 7750 IDXD objects, 1485577 unnamed field entries, 7094 distinct never-named keys splitting cleanly into 7052 in an ordinal band (<=0x2198, 94.6% equal to their own field index) and 42 hash-shaped (>=0x2677C), with ZERO keys in the gap between. The 42 carry exactly 504 entries -- six language copies of one object times two records. So the preimage target was 42, not 504, and my earlier wording invited the misreading. Cross-referenced to the idxd-unnamed-keys write-up, which shows the 42 belong to <lang>\script\ID.tbl and cannot be recovered from a 24-bit hash.
