CottonWorks explains yarn numbering and twist in its spinning material. That provides a concrete starting point for an AI exercise in which a bare number is insufficient to identify a yarn specification. CottonWorks yarn spinning
Create fictional cone tickets, a laboratory sheet and a mock knitting order. Give two yarns the same numeric count but explicitly different count systems. Add a plied-yarn notation and a twist result with its direction. Ask the assistant to match only the supported specification and identify any missing unit or construction information. The key should reject a match based on the repeated number alone.
Label count system, ply, twist unit, direction and lot separately. If the exercise includes a conversion, supply its definition and inputs. Evaluate with a new cone-ticket layout and unfamiliar product names. Score wrong-system matches independently from transcription errors. A model should also identify a complete match, so uncertainty is rewarded only when the evidence actually has a gap.
Start with invented cone labels and original test tables. Real customer yarn requirements and outside laboratory reports need permission for reuse. A spinner's proposal should identify the specification-reading task and reviewed examples. Agree on the buyer's needed combinations and annotation format before collecting a larger archive of operating records.

Original Fiund exercise
Which yarn report belongs to the knitting trial?
A fictional mill sends a cone to an internal knitting trial. All labels and measurements are fabricated; the trial needs a document link, not a yarn specification.
| Record | Source | What it records |
|---|---|---|
| Y1 | Cone ticket | Cone K04, parent lot L12, sample role: knitting trial. |
| Y2 | Lab register | Report R77: cone K04, finished yarn, linear density in tex, twist recorded as S. |
| Y3 | Lab register | Report R78: cone K40, finished yarn, linear density in tex, twist recorded as Z. |
| Y4 | Order note | Order O51 asks for finished-cone evidence for K04; no tolerances entered. |
Question for the model
Which report belongs in the trial packet, and what decision remains open?
Show the reference answer and checks
Attach R77 (Y2) to O51 (Y4) by the exact K04 identifier on Y1. R78 (Y3) concerns K40, even though both records use tex. The packet can identify the observed twist direction and density basis, but cannot declare conformance without an applicable tolerance.
- Swapping K04 and K40 after normalizing identifiers
- Treating a measured direction as evidence that the order specified it
Fields to preserve
- cone_id
- Joins order, sample and laboratory record
- measurement_basis
- Distinguishes finished yarn from precursor and keeps its units
- acceptance_reference
- Leaves conformance unscored where the tolerance is missing
Test another case
Give two cones with the same parent lot and withhold the sample-to-cone map. Score abstention even if both reports agree on twist.
Use invented tickets and original fiber photos; omit proprietary blends, operating settings and real customer specifications.
