The DLBS 1.3.0 episodic memory file is an exact copy of its working memory file
We checked all six cognition workbooks in DLBS release 1.3.0. The episodic memory file is an exact copy of the working memory file. Both files have 658,773 bytes and the same pinned content key. All three sheets report Working Memory, construct 2, and tasks 4 to 9. The six files have no task 15 to 19 columns or Hopkins recall columns. A separate cell reader and a fresh download confirmed the result. The other 15 sheets pass the tested construct checks. We also recovered the distinct episodic memory file from release 1.2.0 through a versioned download. It has the expected construct 4 labels and recall fields. The package preserves both releases of that file, source hashes, code, check results, and a recovery recipe. An analysis gate stops use of the incorrect construct file. This result concerns released file identity. It gives no result about brain and memory relations.
