## Independence conditions

- Fresh independent clone: **true**
- Independent retrieval: **true**
- Authoring-agent artifacts used: **false**

## Checked scope

- Exact candidate bytes, dossier identity, and Git binding
- Primary artifacts, public data workbooks, and exact source spans
- Lineage topology, count derivation, target baselines, and limitations
- License treatment, deterministic rebuild, and full repository check

The receipt binds 4 candidate files, 29 source receipts, and 86 span records.

## Limitations

- This is a bounded lineage case study through the declared cutoff, not a systematic review or effect-size estimate.
- The unpublished Skurnik, Yoon, and Schwarz 2007 manuscript and participant-data identity remain unavailable; that lineage is explicitly unknown and receives zero evidential credit.
- Raw automated captures for Schwarz 2016, Carnahan and Garrett 2020, and Rich and Zaragoza 2016 remained unavailable; their quote-minimal exact spans were independently read from authoritative publisher renditions.
- The Bristol Ecker-Hogan and Edinburgh Pluviano endpoints regenerate raw PDF covers; capture-specific raw digests changed while the declared pdftotext semantic digests and exact spans reproduced.
- Distinct participant-data roots do not imply independent research programs; shared authors, recruitment frames, methods, ethics series, and materials remain separately disclosed.
- Restricted works are represented by metadata, digests where available, and quote-minimal attributed excerpts; full provider artifacts are not redistributed.
