cited identity · physical identity not yet accepted
What is actually verified
The official evidence supports the displayed name or model label. SewGraph has not yet accepted one exact physical-machine entity for this route, so no compatibility answer is attached.
A cited label is not proof that similarly named, regional, revised, or same-code machines are physically identical.
Compatibility first
These states come from the cited public evidence, not from model-code patterns. Unknown is never treated as incompatible.
AnswerNot established from current official evidence
No source-supported value was established; no inference is made.

Compatibility field map
A core answer does not complete every physical axis. Each field below is shown only when current accepted OEM evidence establishes it; all other axes remain explicitly unestablished.
Important: loading style does not establish Bobbin class, hook orientation, or interchangeability.
Important: a recommendation is not an exclusive system requirement unless the OEM says so.
Important: a Snap-On attachment does not establish shank height, holder geometry, stitch-width family, or broad foot fitment.
Cited machine facets
Identity families, physical traits, and OEM accessory groups stay separate. A group badge applies only to its named program and domains.
Identity
Model codes, marketing names, and series are separate cited facts. Search-only spelling variants are not presented as aliases.

Core domains answered: None yet
Domains with cited compatible items: None yet
Unknown is not incompatible. A missing answer means the current official evidence does not support one yet.
This machine is included because its exact identity is cited in an official OEM document. We are not publishing specifications or compatibility until those claims clear the same evidence gates.

Every passage below says exactly what visible fact it proves. Repeated references to the same locator are counted once; identity evidence never counts as compatibility evidence.
Compatibility proof passages: 0. The passages below support identity facts only.
What this passage proves

What this passage proves
sewing computer model artista 640. Power Switch
What this passage proves
BERNINA continues the long-standing tradition of the famous artista family with the model range artista 630 and 640.
Evidence review status
Dossier review completion means every tracked facet received a disposition; it does not mean every machine fact or compatibility axis is known.
Supported public fields (3): physical identity, preferred official name, product line
Unresolved fields (10): aliases, bobbin, lifecycle market, machine type, model codes, needle, oem program groups, part relationships, presser foot, series
Review controls checked (2): source documents and publication/conflict handling are process receipts, not additional machine facts.
Blocked facets: oem program groups, part relationships
Review pass complete — not “all known.” Every tracked field has a recorded disposition; the unresolved fields above remain unknown.
Current blockers: blocked:oem program groups, blocked:part relationships
