Known metadata gaps
Recorded explicitly rather than guessed.
- The checksum recorded here is of Appendix 5, the metadata document, retrieved on 2026-09-08 and read in full for Phase 12. Data Series 801 is a publication of several files rather than one artefact, and the per-file checksums are on the dataset record.
