Partial provenance

This entry is assembled from traceable records.

This is not a reconstructed day. It is an excavated day.

Because

  • · primary diary identified (断腸亭日乗)
  • · date of entry indexed
  • · Fact / Observation / Interpretation mapped
  • · Unknowns explicitly listed
  • · interpretive layers separated

But — blocking Complete / Strong

  • · Edition not identified
  • · Page reference not indexed
  • · SourceCapture not registered
  • · Source copy not examined
  • · Daily boundary not registered
  • · Rights policy not fully reviewed
  • · External cross-check incomplete

Provenance measures trail completeness — not “verified truth” or 100% historical certainty. Reference Entry: no · Reference Entry requires Strong or Complete provenance. Bibliographic trail incomplete.
