Document-source diagnostics
These records identify rejected document reads. A current epoch does not prove that a replacement read succeeded. Later success does not erase an earlier evidence limit.
Inspect 5 rejected reads
An epoch identifies a document generation. Superseded means the document changed. Internal means a browser-owned document. Unavailable means the source identity could not be read.
Ordinals are zero-based. Unknown navigation indexes remain unknown. Scroll the table horizontally to inspect all columns.
