Design walkthrough

How Transit Risk Decision Integrity works.

This is a synthetic demonstrator. It shows how a transit risk alert can become an authorised intervention with attributable evidence, structured outcomes and KATLAS-signed receipts — without centralising customs or trader data and without replacing existing systems.

Nine steps

From anomaly signal to attributable outcome.

Each step shows where the boundary holds. Customs and cargo data does not leave local custody. Analytics services may suggest; authorised roles decide; KATLAS signs the receipt.
  1. 01

    Fragmented customs and transit estate

    Declarations, manifests, border events and trade documents sit across multiple services. A catalogue may describe what exists, but it does not by itself govern what may happen next.

  2. 02

    Movement event or declaration arrives

    A transit movement, declaration or manifest event enters the estate from a partner service. Source services retain custody; only references travel.

  3. 03

    Analytics or rules engine identifies anomaly

    A partner analytics or rules engine flags an elevated risk signal — document mismatch, route deviation, seal contradiction, documentary gap or multi-signal corroboration.

  4. 04

    KATLAS opens a governed Risk Decision Case

    A Risk Decision Case is created with the anomaly summary, source service, rule/model version, confidence band and data-quality caveats attached.

  5. 05

    Evidence provenance and caveats are assembled

    Supporting and contradictory evidence references are assembled with custodian and provenance markers. Withheld evidence is counted but not exposed.

  6. 06

    Correct authorised role receives action request

    The action request is routed by role: case officer, border officer, rule owner or supervisor. Each role only sees actions it is authorised to take.

  7. 07

    Hold / inspect / clarify / release / escalate

    The authorised officer records the intervention. Each action captures actor, role, rationale, evidence sufficiency note and policy basis.

  8. 08

    KATLAS issues a receipt

    KATLAS signs a receipt for each material intervention: alert created, action requested, inspection performed, hold applied, clarification requested, release issued, escalation raised or case closed.

  9. 09

    Outcome returns to learning loop

    Confirmed non-compliance, false positives, intelligence gaps and rule-refinement signals are recorded so the rules and operations improve over time.

Architecture comparison

Centralised risk platform vs federated operating view.

Centralised risk platform

A single database.

  • pushes for full data pooling across services
  • obscures local custody and accountability
  • can blur action authority across teams
  • can make justification retrospective
  • creates another single point of failure

Federated operating view

A shared view, not a shared store.

  • movement data stays under source custody
  • evidence references travel, not raw data
  • authority is explicit at decision time
  • receipts make interventions reviewable
  • outcomes feed back to rules and operations

For advisory audiences

Design ideas this demonstrator is intended to inform.

  1. 01

    Intervention integrity, not just risk score: a high risk score does not authorise an action.

  2. 02

    Evidence provenance must travel with the alert — including what is withheld and why.

  3. 03

    Policy-bound action: every intervention names the policy, rule version and authorised role.

  4. 04

    Feedback for rule refinement: false positives and confirmed non-compliance return to the rules service.

  5. 05

    Federated governance can sit alongside existing customs and border systems, not on top of them.

  6. 06

    Operational truth is reviewable through receipts, without exposing trader or cargo data.

Synthetic, non-procurement disclaimer

This is a synthetic demonstrator, not a replacement for CDS, NCTS, GVMS or Border Force operational systems. The purpose is to show how a risk alert can become a governed intervention with clear authority, attributable evidence and structured learning. KATLAS provides the decision-integrity layer between risk analytics and operational action.

Follow it end-to-end

The control room applies this nine-step pattern to five synthetic transit cases. Open one to see the evidence boundary, the authority gate, the recommended actions and the KATLAS receipt status.
