Known Limitations
- A shared-post event does not guarantee that Facebook exported the complete original third-party post text.
- 1,543 shared-post records preserve the sharing event while source text is absent.
- Video metadata is indexed, but the large video binaries were not included in this intake.
- The separately downloaded HTML Posts export and the larger full-account export remain pending comparison.
- Public still images are visual-access derivatives; original-resolution files remain in the private accession.
- Facebook-generated titles and export schemas may be repetitive or ambiguous. The archive preserves those boundaries rather than inventing missing context.
