One part, one code, one identity
Requirement v0.1Autonomous receiving cannot interpret a handwritten label. So Moduloa puts one uniform requirement on every supplier whose parts flow through a hub: everything arrives carrying a single 2D code holding a single globally unique identifier that resolves to supplier, part, revision, and lot or serial. Every part identified equally — whether it comes from a catalogue giant or a two-person machine shop. This page is the requirement, its reasoning, and the zero-cost path for the smallest supplier.
This problem has been solved before — four times
Uniform identification across thousands of unequal suppliers is not a new problem. Four industries solved it, each teaching one lesson this requirement copies.
Today's EMS baseline is a Code 128 logistics label with part number, quantity, and lot — what the largest contract manufacturers require on incoming goods right now. This requirement is deliberately one step ahead of that baseline, and cheaply: a single 2D code whose content is a URL-capable identity, which is precisely the envelope the EU's Digital Product Passport standards fixed this month — the identifier and carrier standards were cited in the Official Journal on 15 July 2026, and both accepted schemes below sit inside them. Parts marked to this requirement are DPP-nodes-in-waiting for the 2027–2030 category mandates.
Five rules
Total capex for the smallest supplier: a label printer and a template. Marginal cost per label: cents. There is no equipment argument against uniform identity.
The requirement binds us too
What we demand of suppliers at the dock, we demand of ourselves on the line. Identity is not only received — it is created, at every step of the build.
On the line, direct marking is a natural task for the flexible layer: a humanoid with a laser engraver marks the closed assembly where a fixed station would need dedicated tooling per product — laser Data Matrix marking is already the automotive DPM standard, and the verification gear to grade it is commodity. It is also, honestly, a hypothesis stacked on a hypothesis: engraving works reliably on metals and many plastics, not on every cosmetic surface or tiny part, so labels remain the fallback the requirement always accepts — and humanoid marking earns its place the same way the rest of the humanoid layer does: measured, on the line, against the alternative.
Identity is what the OS stands on
Every autonomous step downstream leans on this requirement. Receiving binds arriving material to intake BOM lines by scan, and checks it against the acceptance criteria with no human interpretation. The execution trace records which lot and serial went into which unit because the parts could say who they were. The shipped batch carries its history because identity never broke between the supplier's dock and the customer's door. And when a supplier confirms a part through the confirmation protocol, the thing they attest and the thing that later arrives are provably the same thing. Uniform identity is not an administrative preference — it is the load-bearing wall of a factory with no one standing at the receiving desk.
What has to be proven
A v0.1 draft, published to be corrected. The named risks: suppliers with entrenched label systems may resist a second code until the transitional lane expires — the bet is that the lane plus the zero-cost fallback removes every honest objection. The Moduloa resolver that makes fallback identities and scan-to-line binding real does not exist yet — this page is its specification. And enforcement is only as strong as the chargeback discipline behind rule M-05, which is a policy commitment in the same spirit as the commercial terms: easy to publish today, tested the first time it is expensive.
