Northbrae Energy is a GB Energy retailer running the full Probari assured chain on a customer-churn use case. The deployment is the reference configuration shown to evaluators — a complete, regulator-grade trace from triage through live signals. Six stages, each tamper-evident and linked to the next so the audit trail cannot be quietly altered. The methodology is reproducible; the outputs below describe what the platform does, not a marketing claim.
STEP 01
Triage
Candidate scored against the Probari prioritisation matrix — five weighted dimensions, jurisdiction-specific regulatory rubric. The agent answers "should we build it?" with a quadrant placement and an audit-anchored rationale.
OUTPUT · triage finding, quadrant, audit anchor
STEP 02
Intake wizard
Use case captured through the Probari intake wizard — purpose, data classes, lawful basis, decision affected, vendor model. Risk tier automatically graded against the EU AI Act schedule, seeded by the triage outcome.
OUTPUT · signed intake record, risk tier, owner
STEP 03
Decision map (DIAMC)
Every decision follows a five-step pattern — Discover, Identify, Assess, Mitigate, Confirm (DIAMC). It means nothing reaches a regulator without being checked the same way every time. The completed decision map produces the structured evidence the AI Impact Assessment consumes. Every stage entry is regulator-cited and reviewable.
OUTPUT · approved decision map, evidence packets
STEP 04
Impact assessment (AIIA)
Forty-seven AI Impact Assessment (AIIA) questions across nine sections, drafted with Perplexity Sonar assistance — the only AI provider Probari uses, chosen because every answer comes with the source — and linked to the upstream decision map. Every answer carries a citation, an author and a timestamp.
OUTPUT · completed AIIA, citation chain, sign-off log
STEP 05
PRD generator & patrol
The approved AIIA auto-generates a Product Requirements Document (PRD) — the build brief engineering works to — using Sonar. A second AI agent (the patrol agent) then runs six structured checks — source anchoring, regulator citation, risk-tier consistency, jurisdiction, approval chain and PM-craft — before any human reviews the work.
OUTPUT · patrolled PRD, six-check report, tamper-evident audit chain
STEP 06
Live signals
Operational signals tracked against the assurance baseline. Drift in input distribution or fairness metrics opens a reassessment ticket rather than a surprise audit. The full chain — triage to signals — replays as an evidence pack.
OUTPUT · signals feed, drift triggers, reassessment queue
Reference configuration in the Probari demo environment. The Northbrae deployment is illustrative — every output above is generated by the live product against real framework text. Six agents in the chain: triage, wizard, decision map, AIIA, PRD generator and PRD patrol.
