Engineering · the umbrella
Evidence-first engineering for the network under the workflow.
Engineering is the BMI2 pillar that ships TestPulse — a diagnostic engine for 802.1X, RADIUS, TACACS+ and EAP-TLS that never returns a verdict without wire evidence to back it. The Virtual Lab is the environment TestPulse was developed against. The Documentation is the same one the engineer reads. Same evidence rule as Fiduciary and AIM, aimed at the network layer instead of the workflow layer.
The engineer behind BMI2
Meet Tarik Riley
An AI systems architect and automation engineer with more than 20 years in IT, including staff and consulting engagements supporting AT&T, Spirent, Verizon, Viasat, and DISH Wireless. I apply that experience to AI services with clear authority boundaries, operational evidence, and measurable acceptance criteria.
What TestPulse does
Four use cases the engine is trained to answer — with citations.
Every TestPulse output is a typed finding with a cause family, the specific counters and log lines that support it, and a fix direction. No verdict is issued without evidence sufficient to defend it in a review.
Diagnosis
What broke, and why.
Structured, evidence-gated diagnosis across RADIUS, TACACS+ and 802.1X. Cause families with detection thresholds — not free-form narrative.
Forensics
Timeline, provenance, ledger.
Reconstruct exactly what happened across log, capture and identity sources. Provenance travels with every claim.
Prognosis
What will fail next, and where.
Forecasts against real observed patterns — advisory, not executing. A prognosis stays a prognosis until a human acts.
Classification
Route the finding to the right hands.
Every finding is classified by cause family, severity and target role so it lands with the person who can act on it.
Two additional capabilities: Compliance — the finding trail is auditable end-to-end. AI Validation — the diagnosis engine is graded against faults it can't see the answer to, and no cause family ships until it clears six gates.
The engineering stack
What Engineering means, plainly.
Engineering is not a marketing bucket. It names the discipline that built TestPulse: system integration, automation and site reliability engineering — now aimed at AAA diagnosis. The Virtual Lab is the same Kubernetes appliance the product was developed against; the User Guide is what a working engineer reads on the console.
Where to go from here
Download TestPulse Pro — the wheel, the SBOM, the release notes. Read the User Guide — plain-text operational guide, no marketing. Get the Virtual Lab — real EAPOL frames on the wire on a single host, if you don't have gear to point at. Watch the demos — four walkthroughs with chapter seeking.
AI engineering in practice
How I build governed AI
Follow my SDLC series on requirements, architecture, secure ingestion, builder/reviewer workflows, evaluation harnesses, CI gates, and accountable human acceptance.
Point it at your own lab and see what it finds.
TestPulse installs as a Python package and runs entirely on your machine. Parsing, correlation, the deterministic diagnosis and the evidence bundle make no network call.
