Geometry-derived
STEP/STL envelope, triangulated body or mesh count, triangle count, surface-area estimate, volume estimate, and limited STL edge checks.
Product claims boundary
Supplier-readiness evidence, not universal manufacturability.
DatumRelay answers one bounded question: does this release package meet the implemented evidence and declared-capability gates for a named supplier profile, and what declared change could remove a blocker?
!
A pass is local to one implemented rule.
It does not mean the part is manufacturable, toolpaths are safe, GD&T is correct, inspection will pass, or the supplier accepts the work.
What the result is built from
The interface keeps four evidence classes distinct so a declaration is not presented as geometry proof.
Human-declared
Material, finish, wall, holes, internal radius, tolerance, surface finish, coating controls, identity, quantity, and evidence source.
Artifact presence
Filename, media type, byte size, and SHA-256 for drawings and inspection plans. Their technical contents are not interpreted.
Passport-declared
Versioned capability limits, allowed materials, finishes, formats, provenance, approval metadata, and expiry supplied by a local profile.
What the qualification client does
Compare one release across suppliers
Evaluate the same package against multiple capability passports. A recommendation exists only when exactly one externally authenticated, current route has the exact rule baseline, zero blockers, and zero reviews; ambiguity returns no recommendation.
Expose exact rule outcomes
Show pass, review, blocker, not-applicable, and not-covered results with evidence and remediation. Any legacy presentation warning is normalized to review in the strict v3 record.
Find cross-supplier unlocks
Turn failed declared limits into concrete review actions instead of hiding them inside a generic manufacturability score.
Carry the evidence forward
Export a strict v3 buyer JSON record, or a buyer ZIP with deterministic views and record-bound artifacts. Supplier ZIPs expose only an allowlisted supplier brief and referenced artifacts. The buyer record carries a canonical profile digest, not the full passport.
Implemented comparison gates
| Area | Current comparison | Evidence boundary |
|---|---|---|
| Identity and package | Part/revision fields, CAD presence, drawing presence, inspection presence, filename revision hint. | Drawing and inspection semantics are not read. |
| Geometry | Accepted format, axis-permuted work envelope, single/multiple mesh or body review, limited STL integrity checks. | No feature recognition, reachability, setup, fixture, or toolpath analysis. |
| Declared features | Minimum wall, hole diameter, hole L/D, internal radius, linear tolerance, and required Ra versus passport limits. | These values are entered by a person, not extracted from CAD. |
| Commercial fit inputs | Declared quantity plus an exact material/finish/CAD-format tuple against the selected passport. | Independent list membership is insufficient. No price, capacity, lead time, logistics, or supplier-risk analysis. |
| Passport governance | Schema, revision, evidence reference, approver metadata, dates, expiry, and content checksum. | No issuing-organization identity or digital-signature verification. |
| Exceptions | Challenges hold release eligibility unless an external trust boundary supplies an authenticated disposition scoped to the release, record, tenant, route, rule, and validity window. | Local resolved status and local disposition text are unauthenticated and never unlock release eligibility. |
Explicitly outside scope
These domains stay not covered. They must be handled by qualified people and approved systems.
CAM and machine safety
Toolpaths, feeds/speeds, cutter or holder selection, collision, stock, fixture, spindle, workholding, setup, and reachability.
GD&T and design analysis
PMI semantics, ASME/ISO interpretation, tolerance stacks, FEA, fatigue, thermal, fluid, vibration, and service life.
Quality execution
Material certification, special-process qualification, metrology, MSA, FAI, final inspection, regulatory approval, and certification.
Commercial commitment
Price, cycle time, capacity, lead time, yield, solvency, sanctions, logistics, purchase authorization, and supplier acceptance.
Browser-local refusal limits
These are early rejection thresholds, not performance guarantees.
