Compliance dossier — training data (AI Act, Article 10)

Automatically generated skeleton from the dataset analysis. The "to be completed by the expert" blocks require human review (provenance, compliance judgment, mitigation measures).

1. Identity & purpose

System / model: _____
Dossier version: _____
Analysis date: _____
Dataset: src
Intended purpose: _____

_To be completed by the expert — intended purpose and what the data is meant to represent_

2. Provenance & legal basis

Origin of each source, licences/contracts, and — for personal data — initial purpose and GDPR legal basis.

⚠️ Potential personal data detected: name, first, last, dob — a GDPR legal basis is required for these columns.

_To be completed by the expert — provenance per source (separate flow §16), licences, GDPR legal basis_

Detected PII columns: name, first, last, dob.

_To be completed by the expert — geographic / contextual / behavioural scope_

4. Preparation _(automatic observations)_

Missing values: days_b_screening_arrest (307) → handling strategy to be documented.

_To be completed by the expert — transformation log: collection, cleaning, labelling, enrichment, aggregation_

5. Quality _(filled automatically)_

Completeness: 307 missing value(s) (days_b_screening_arrest).
Accuracy / outliers: age (1).

_To be completed by the expert — representativeness and relevance to the purpose_

6. Bias

Automatic analysis

Characteristic	Measure	Target	Verdict
Completeness	81.4 %	≥ 95.0 %	to address
Uniqueness	100.0 %	≥ 99.0 %	compliant

race — « score_text »: disparate impact (ratio) 4.83 · statistical parity (gap) 26.4 % ⚠️

_⚠︎ Non-robust disparity: smallest group n=18 — not statistically significant or driven by a small sample. Do not read as an established bias._
