Quality & verification

A check that has never failed is decoration.

Every stage of our process carries deliberate failure cases — tests written to catch that stage doing the wrong thing convincingly, not just to confirm it working.

The principle

A part can pass every check and still be wrong. Volume is a scalar: it cannot tell a correct feature from an incorrect one that removes the same amount of material. A toolpath can lie inside the part boundary at every sampled point and still gouge it, because membership is not order.

So nothing here is verified by a single instrument. A dimension is derived in closed form and measured off the built solid, and disagreement between the two is a refusal to report — never an average, never a preferred source. Where we can only measure one way, we say so.

The rule

Two independent channels, or the measurement refuses. Applied to geometry, to material removal, and to cutter position alike.

The fixture

A test case sits exactly on every limit. A wall at precisely the minimum is accepted; one micron under it refuses. Off-by-one boundary errors do not survive that.

The control

Each stage is handed input it must REFUSE — a tool that cannot cut the geometry, stock smaller than the part, a part outside the family. A stage that accepts everything proves nothing.

Measured

What the checks returned.

Recorded from an actual run of the code, not transcribed. Each module’s source is hashed into the record, so a change after the fact is detectable rather than silent.

Verification record Recorded 2026-09-01 20:45 UTC
PASSGeometry derives and self-checks
closed-form area against the built solid, with fixtures exactly on the wall-thickness and lug-ratio limits
44 checks · 5 refusals
PASSOperations account for removed volume
planned removal must equal stock minus part; drill-diameter and depth fixtures sit exactly on their limits
27 checks · 5 refusals
PASSToolpaths are exact and gouge-free
closed-form cutter offset, plus controls that refuse an impossible tool and catch a 0.05 mm perpendicular deviation
3 controls
TOTAL3 of 3 modules pass
recorded under Python 3.13.12; each module’s source is hashed into the record
71 checks · 13 refusals

Two independent signals must agree before a module is recorded as passing: the process exit status and the module’s own verdict line. A script that prints a failure and exits zero does not count as a pass.

Quality system

What we hold, and what we do not.

We are a new entity. We hold no third-party quality accreditation, and we will not imply one. The verification above is our own, it is reproducible, and it is the part of a quality system we can demonstrate today.

A documented quality management system is specified as part of standing up production, and we will state its status here when it is real — the same way this page states everything else.

Third-party quality accreditationNone held
Documented QMSSpecified — not yet implemented
Calibrated inspection equipmentSpecified — not yet purchased
Process verificationIn place — see the record above
Prior federal contract awardsNone to date

We would rather a buyer learn this from us than discover it during a source inspection. If a requirement calls for accreditation we do not hold, we will say so at enquiry rather than at award.
