CONTROLLED FIXTURE BENCHMARK

How smart ordering is tested.

Controlled generated PDFs evaluated by the production deterministic ordering service. This is evidence for supported signals, not a claim of general accuracy.

TEXT-DATE

Dates written inside documents

Pass

The filenames point in the wrong direction, while visible document dates define the timeline.

Expected
  1. m-project-start.pdf
  2. z-project-update.pdf
  3. a-project-close.pdf
Alphabetical / mismatch
  1. a-project-close.pdf

METADATA-DATE

PDF creation dates

Pass

No visible date is present, so the embedded PDF creation date provides the sequence.

Expected
  1. m-intake.pdf
  2. z-review.pdf
  3. a-approval.pdf
Alphabetical / mismatch

DOCUMENT-NUMBER

Invoice numbers

Pass

Invoice numbers inside the PDFs define the sequence when dates are unavailable.

  1. m-north.pdf
  2. z-central.pdf
  3. a-south.pdf

PAGE-MARKER

Page markers

Pass

Page X of Y markers reconstruct a three-part packet despite misleading filenames.

  1. m-packet.pdf
  2. z-packet.pdf
  3. a-packet.pdf

FILENAME-DATE

Dates in filenames

Pass

Dated filenames provide the fallback sequence when document text and metadata contain no usable signal.

Expected
  1. m_scan_2025-01-08.pdf

METHOD AND LIMITS

What this result means

  • These fixtures validate supported deterministic signals, not real-world accuracy.
  • The optional model-backed ordering path is not used in this benchmark.
  • Scanned PDFs without extractable text are outside this controlled fixture set.
