Key takeaways
  • Build a single navigable technical file that proves safety, performance and compliance — not a pile of PDFs.
  • Every claim links to evidence; every control links to owners, thresholds, tests, and results.

Scope & purpose

  • Intended purpose, target users, environments, exclusions and dependencies; product variants.
  • Regulatory mapping: AI Act title, sector laws, CE/UKCA routes, standards list (e.g., ISO/IEC 42001 family when available).

System architecture & context

  • Diagrams of data flows, components, APIs, third-party services, monitoring, key custody and isolation boundaries.
  • Operational modes (normal, degraded, paused); rollback and kill-switch architecture.

Data sources & governance

  • Source registry with provenance/licences, lawful basis, cohort notes, retention; lineage graphs.
  • Privacy engineering: minimisation, redaction, unlearning approach, DSR handling.

Models & training

  • Model cards; training/finetune recipes; hyperparameters; guardrails; content filters; jailbreak protection.
  • Supplier attestations for foundation models; constraints and intended use statements.

Evaluation & performance

  • Test plans and results: accuracy, robustness, bias/parity, safety red-team, and stress/load.
  • Acceptance thresholds by cohort; unresolved gaps with risk rationale and roadmap.

Risk management cross-refs

  • Link to RMS register items; control implementations; evidence (logs, dashboards, approvals).

Security & privacy controls

  • Threat model; segregation, secrets, egress controls; anti-prompt injection; content moderation pipeline.

Human oversight & UI

  • Operator roles, permissions, explainability widgets, uncertainty cues, and override mechanisms.

Post-market monitoring plan

  • Metrics, alerts, sampling, escalation, and CAPA workflow; regulator notification triggers.

Change control & versioning

  • Model/data versioning; release approvals; rollback criteria; waiver handling; periodic reassessment.

Evidence pack structure

  • Index page; requirement→control→evidence matrix; snapshots per release; immutable incident bundles.

Technical file checklist

  • Scope/architecture documented; data/model cards complete; evaluations attached; RMS & PMM linked; approvals signed.
