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 direct bobbin class, dimensions, material, part number, or bobbin-case answer is established.

Answer134 SUK
Direct exact-scope native evidence establishes Needle system 134 SUK for LZ-2284B-7. The adjacent Nm70 text remains preserved only as an untyped source token: it is not promoted as a size, range, default, recommendation, minimum, maximum, exclusivity claim, or conversion.

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.
Evidence coverage
Machine category: Not yet established
Core domains answered: needle
Domains with cited compatible items: None yet
Unknown is not incompatible. A missing answer means the current official evidence does not support one yet.
Specifications
Multiple cited representations for one field share one row. SewGraph preserves every value and exact proof passage; it does not guess which representation is “raw” or “normalized” when the public projection does not label that distinction.

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 (4): model codes, needle, physical identity, preferred official name
Unresolved fields (9): aliases, bobbin, lifecycle market, machine type, oem program groups, part relationships, presser foot, product line, 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
