PYX: supplier qualification

Four tasks

PYX · for the suppliers. Tested once against an independent standard, so no customer has to test it again.

A supplier would qualify once, against one published standard, and could then supply any product on Moduloa that needs what it makes, the way a marketplace works. The standard would cover what may be supplied as well as who, including the substitute for a part that goes out of production. A supplier you name can be priced in a quote before it qualifies, with its confidence reduced, and is used in production only once it has qualified.

Why the name. Since 1248, an independent jury has tested coins from the Mint's own production in the Trial of the Pyx.

Why it matters. Every part Moduloa builds with is bought. Every unit is only as good as its suppliers, and a qualification each customer has to repeat is the cost this is designed to remove.

The shadow system it is designed to replace. Supplier lists and audit evidence kept in spreadsheets and binders, repeated for each customer, sometimes with two standards running side by side. In the design, a supplier's qualification would live once, as one record against one published standard, read by every quote and every route, and a part that changes would get a new revision and code instead of shipping under the old one.

Research behind it, thin. A production qualification does not travel · One per hour, ten thousand parts No note is about supplier qualification itself, two touch it in one section each, and there is no qualification page and no supplier object yet. The least researched of the five.

Inside it

What it is made of

The pieces of the work that live in PYX. Each is written as designed: none of it runs yet.

What a supplier's quality system must prove

It is the qualification standard itself (Q-01, Q-02).

The regulated industries set the floor the standard would start from. Automotive's IATF 16949 makes an ISO 9001 certificate the initial minimum for a supplier unless the customer allows less, and works toward IATF 16949 certification itself, while ISO 13485 for medical devices requires suppliers to be evaluated and re-evaluated in proportion to the risk the purchased part carries. Moduloa's standard would add what those leave to each customer: one set of evidence, one surveillance interval, and the conditions under which status is lost and regained. It is not written yet, and no supplier has been qualified.

Obsolescence and continuity

Qualification covers what may be supplied as well as who: end-of-life notices and qualified substitutes (Q-04).

Parts go out of production during a product's life, and the warning can be short. JEDEC's discontinuance standard, in the 2011 edition the site cites, required at least six months from notice to last order and twelve to last shipment; it was superseded in December 2025 by J-STD-048A, which sits behind a login and has not been checked here. Some chipmakers give more: Texas Instruments gives twelve months to order and six more to take delivery. Every part on your BOM would be watched for notices, and you would choose a last-time buy, a qualified substitute or a redesign, seeing any substitute before it ships. Nothing watches a BOM yet.

The cost of a last-time buy lands in CHEQUER, and a redesign it forces is a new JACQUARD revision.

The work

Tasks

Several people can work on the same task, each with its own deliverable. Ask to commit with the link on a task: name what you will deliver and a date no more than three months after it is accepted.

Q-01Open

Qualification standard v0.1, an outline

Done when
For four process classes (machining, moulding, circuit board assembly and cable harness), a draft states the evidence a supplier brings on top of its ISO certificates, how often it is checked again, and what loses qualification and what restores it. It covers a supplier the customer names, which a quote can price before it qualifies but production uses only after, and says how a material certificate reaches the unit record while handover parts stay black boxes (intake rule V4).
Effort
Four to six weeks, part time

Ask to commit to Q-01 →

Q-03Open

Supplier record schema

Done when
A JSON Schema for a qualified supplier: its registry identifiers in the intake schema's own form, its scope by process class, and a dated status history (qualified, suspended, lost). One example with a simulated identifier validates against it, and a note says how it would join the factory OS model, which has no supplier object yet.
Effort
One to two weeks, part time

Ask to commit to Q-03 →

Q-04Open

Part lifecycle and substitutes

Done when
A proposed change to the intake schema adds a lifecycle status with its source and date, and a last-time-buy date, to each BOM line. A written rule says which substitutes need the customer's approval before they ship, and settles where the alternates policy's standing consent and the promise that you see any substitute first disagree.
Effort
About two weeks, part time

Ask to commit to Q-04 →

The honest limits

What is open, and what would prove it

  • No qualification standard exists yet. The link the site gives for one leads to the intake standard, which covers verification only.
  • Handover parts are black boxes under intake rule V4, yet traceability is meant to reach the material certificate. How both hold is open (Q-01).
  • The alternates policy treats any form-fit-function equivalent as standing consent, while the journey promises you see any substitute before it ships. One of them has to change (Q-04).
  • No register claim tests supplier qualification directly.

On the register

  • P-17 · due 31 December 2046 · open · makers relying on lock-in and opaque pricing lose ground to certified, interoperable networks
