Validate real eye-tracking exports and compatibility corpora

Build reproducible evidence for source-format compatibility. The validation framework distinguishes declared support, synthetic-fixture testing, and empirical validation with real exports. It audits source structure, adapter detection, canonical import, field coverage, native timestamp preservation, coordinate semantics, provenance, and canonical round-trip fidelity.

Details

validate_eye_source() validates one file or folder. Use validation_manifest() and validate_eye_corpus() to evaluate a versioned collection of exports from multiple vendors, devices, and software versions. init_validation_corpus() is idempotent and preserves an existing manifest and case files unless overwrite = TRUE is supplied. A source can be retained temporarily in the result for creation of an anonymized validation bundle; raw vendor data are never included in bundles by default.

anonymize_eye_dataset() replaces participant, recording, and session identifiers, removes raw tables and source paths by default, and records the operation in provenance. Automated anonymization cannot guarantee removal of all study-specific free text, so exported bundles still require human review.

Value

Depending on the function, an eye_format_validation_spec, source-file manifest, schema-coverage table, source-preservation audit, canonical round-trip result, eye_format_validation, eye_corpus_validation, anonymized eye_dataset, report path, or validation-bundle path.
