Primes¶
- Designed-Out Misuse
- the misuse path costs exploitation effort while the legitimate path runs unmodified. Product safety (poka-yoke): child-resistant caps, asymmetric connectors that fit only one way, dead-man switches

Domain-specific¶
- Friction Budgeting
- It subsumes the nudge case, it is not identical to it. Not error-proofing. Poka-yoke forcing functions are one load-bearing reason to add friction at a step
This sourceShingo's account of poka-yoke devices and source inspection as mistake-proofing that catches errors before they become defects.

Mechanisms¶
- Context Restructuring
- Restructuring so the unwanted response cannot easily assemble is a form of poka-yoke, or mistake-proofing: designing the process so the error is hard to make rather than relying on people to resist it.
This sourceDefines poka-yoke as redesigning process conditions so errors are difficult or impossible rather than relying on vigilance.

- Physical Impossibility Design
- Its strength is the most reliable check there is: a slip that is geometrically impossible has a defect rate of zero and needs no vigilance, no power, and no software — the "control" form of poka-yoke that Shigeo Shingo distinguished from a mere warning.
This sourcePresents poka-yoke control devices as mistake-proofing interventions that prevent or stop errors rather than merely warning about them.

- Physical Keying or Interlock
- Its strength is the strongest guarantee in the archetype: a correctly keyed connection eliminates an entire class of catastrophic physical error unconditionally, independent of attention, training, language, or power — the canonical poka-yoke.

- Safety Interlock
- Its strength is turning "operators must be careful" into a physical guarantee: harm is prevented at the actuation point, the earliest placement possible, embodying mistake-proofing so the unsafe transition cannot be made rather than merely being discouraged.

Verification¶
Does it exist? Not confirmed. The DOI recorded for this work did not resolve when it was last checked, so it is shown above but not linked. The citation may still be sound; the recorded identifier is not. Flagged for repair.
Does it back the claim? Read against the text for 1 of 7 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
