PDF corpus: inspect the files behind the results

Inspect OfficeIMO PDF corpus results with source hashes, licenses, rendering, extraction checks, mutation decisions, failures, and reproduction commands.

These results come from the existing OfficeIMO PDF quality runner. Each input has a pinned source and SHA-256 hash. The runner opens it, exercises public APIs, and compares the outcome with explicit expectations.

A passing case means those expectations were met. It can include a safe refusal to modify a file. A rendered page, extracted text, or declared PDF/A marker does not establish visual fidelity, reading-order accuracy, or standards conformance.

Measured PDF quality run

14 unique files · 14 of 14 cases met expectations · 0 failures · 0 timeouts.

112 of 112 operational checks completed; 141 of 141 pinned expectations passed.

The render check uses managed SVG output for at most 4 pages per file. Mutation checks assess preservation plans; they do not prove that every planned edit was saved and reopened. Compliance checks inspect declarations and do not certify them.

Reproduce this corpus

Check out the source revision above, then run:

pwsh ./Build/Test-PdfQualityCorpus.ps1 -Framework net10.0 -OutputDirectory artifacts/pdf-quality-corpus

The run checks the manifest and input hashes before processing. Keep the environment and engine artifact with any new result; a fresh run may have different timings.

Other evidence answers different questions

EvidenceWhat it establishesWhat it does not establish
PDF performance workloadsValidated equivalent work and measurements for the recorded environmentPerformance on every document or machine
Office producer referencesPinned Microsoft Office output, rendering distances, and declared budgetsPixel equivalence or universal Office compatibility
PDF interoperability input catalogReproducible input selection with provenance and licensingA completed run for every listed input
Reverse conversion scorecardRoute-specific serialization, reopening, and semantic or visual contractsReconstruction of the original editable source

The catalogs can overlap. Their entry counts must not be added together as a unique-file total. OCR accuracy, certified conformance, and large external-corpus stress results are separate evidence requirements.
