Provenance

Every profile carries generation.global_seed, generation.profile_seed, generation.sdk_version, and generation.reference_manifest_hash, which together identify the deterministic generation context. Re-running with the same --seed and pinned generation date reproduces the generated content including generation.generated_at.

Validation

Per-locale KS gaps (smaller = closer to reference data) and consistency-rate.

Locale	age_ks_M	age_ks_F	edu_ks	marital_ks	consistency
US	0.104	0.100	0.004	0.091	100.00%
UK	0.101	0.093	0.011	0.095	100.00%
IN	0.124	0.124	0.002	0.104	100.00%
CA	0.109	0.102	0.007	0.080	100.00%
AU	0.116	0.102	0.010	0.083	100.00%

Release target: KS <= 0.10 per attribute and mean <= 0.07. This v1.0 release discloses the observed gaps rather than tuning them to force the target.

Leakage audit

Audit	Profiles checked	Findings	Mode
self_collision	100000	1045	exact
wikidata	100000	342	bloom
email	100000	0	syntax_only

Wikidata audits use a Bloom filter (FP rate ~1e-4); reported leak counts are upper bounds.

Bias and limitations

• Reference distributions are 2021–2023 census/ACS bootstraps; living populations drift, and the dataset does not reflect post-2023 changes.
• Cross-household family edges (extended family) are deferred to v1.1.
• households.composition_type_inferred is derived from represented family edges and member ages, not from the original generator spec. Because v1 is adults-only, *_with_children means represented adult children.
• employment.parquet keeps the current employer first and historical jobs after it with valid_to populated.
• Phone and address fields are generated synthetically and should be treated as test data, but plausible strings can still coincide with real-world records by chance. Release leakage evidence is published in the leakage section.
• Income, net worth, and credit scores are statistical realisations, not individual-truth values. Don't use them for downstream decisions about real people.
• This release contains structured Person Objects only. It does not include auxiliary generated-content datasets.
