The credential
Type ratings, not certificates of attendance
Borrowed from civil aviation: a credential names the platform, the environment and the expiry, because competence on a bipedal humanoid in a sterile suite says nothing useful about competence on a quadruped in an energised substation.
Anatomy
Reading a HeliX rating
HeliX L3-PAI / ENR / QUADRUPED-INSPECTION CLASS / SUBSTATION-ENERGISED
Holder: [name] · Examined: 2026-11-14 · Examiner: [ID] · Valid to: 2027-11-14
Endorsements: confined-space entry · degraded-comms teleoperation · live blue-team response
Level & pillar
L3 Engineer with Physical AI emphasis
Vertical
Energy, utilities & mining
Robot class
Quadruped inspection class
Environment
Energised substation
A rating is invalid outside any of those four terms.
Examination
Independent by construction
Examiners do not teach the candidate they examine
Examiners are warranted L5 holders in Zone 9 who report to the Safety & Assurance Board, not to faculty. That separation is why the credential is worth anything to a third party.
Safety failures are absolute
One safety violation in an examination is a fail at every level, irrespective of aggregate score. There is no compensating for it elsewhere.
Examination happens on live hardware under injected failure
A candidate who has only been assessed on a working fleet has not been assessed.
Every failure decision is appealable and recorded
Inter-examiner calibration is measured quarterly; examiners who drift from the calibrated standard are re-trained or lose the warrant.
Revalidation
Everything expires in 12 months
Recurrent training is not an afterthought — at scale it is the largest single source of returning learners. Recurrent checks are priced at $1,400–$4,800 depending on level.
| Credential | Validity | Recurrent requirement |
|---|---|---|
| L1 Operator | 12 months | 2-day recurrent check: practical, safety, and one injected failure scenario |
| L2 Technician | 12 months | 3-day recurrent: return-to-service audit plus updated platform differences |
| L3 Engineer | 12 months | 3-day recurrent: policy evaluation exercise plus blue-team scenario |
| L4 Architect | 24 months | 5-day recurrent: architecture review and incident command exercise |
| L5 Examiner warrant | 12 months | Quarterly calibration participation plus annual Board review |
