```{r setup, include=FALSE}
knitr::opts_chunk$set(collapse = TRUE, comment = "#>")
```

eyeprocess 0.9 consolidates hashes of data, decisions, model specifications, results, package versions, files, and the R environment into a reproducibility fingerprint.

```{r, eval=FALSE}
fp <- eye_reproducibility_fingerprint(data=data, analysis_spec=spec, decisions=manifest, result=fit)
write_reproducibility_fingerprint(fp, "fingerprint.rds")
verify_reproducibility_fingerprint(fp)
```

Lineage nodes and edges can be represented using PROV-like relation labels, exported as compact JSON, or written as Graphviz DOT. `export_ro_crate_metadata()` writes minimal RO-Crate 1.3 metadata. The package intentionally describes this as interoperability scaffolding rather than claiming full external conformance without independent validation.
