XFDF twin of the acro-signature-placeholder form data - the same field names and values as the FDF, in Adobe's XML representation. Convert one into the other and the result must be byte-comparable field for field.
A signature block drawn as a ruled area with named text fields - not a digital signature field. This HTML twin carries the same canonical field names as the AcroForm PDF of the same name, so a filler can be tested against both representations of one form.
Text fields carrying the comb, multiline, password and read-only AcroForm flags. A one-page fillable AcroForm whose canonical field names match the HTML twin, the FDF and the XFDF of the same name, so one form can be tested across four representations.
Adobe FDF form data for acro-text-field-flags.pdf: every canonical field with the value the PDF ships. The XFDF file of the same name carries the identical values, so the pair is a round-trip test of an FDF and XFDF converter.

Text fields carrying the comb, multiline, password and read-only AcroForm flags. This HTML twin carries the same canonical field names as the AcroForm PDF of the same name, so a filler can be tested against both representations of one form.
The screen an address verifier shows after standardising an entry: the original and the suggestion side by side as a radio choice, plus editable fields prefilled with the standardised form.
A pure 1 kHz sine tone stored as AIFF: Apple's big-endian 16-bit PCM container, 3 seconds, 44.1 kHz mono. A clean reference for testing AIFF decoders and WAV↔AIFF conversion.
A pure 440 Hz sine tone stored as AIFF: Apple's big-endian 16-bit PCM container, 3 seconds, 44.1 kHz mono. A clean reference for testing AIFF decoders and WAV↔AIFF conversion.
An Airflow DAG definition in the classic operator style, using only the no-op EmptyOperator so the file describes a topology and performs no work. Carries the six-task ETL graph shared across the Airflow JSON, Argo, Graphviz and Mermaid fixtures.
A decorator-based Airflow TaskFlow DAG where dependencies are implied by function calls rather than >> operators: the shape static DAG extractors most often get wrong. Every task returns a literal, so nothing performs I/O.
The serialized-DAG shape Airflow stores in its metadata database, as standalone JSON: per-task metadata with explicit downstream_task_ids. Carries the same six-task topology as the Python, Argo, Graphviz and Mermaid fixtures.
An airline boarding pass laid out as a landscape PDF: passenger, flight, gate, seat, PNR, and a decorative barcode strip. A fixture for testing document-layout parsing and field extraction. Synthetic; the barcode is decorative.
