Frozen produce rework records for AI lot tracing
When material returns to a process, the usual one-input-to-one-output diagram stops working.
NAICS 311411 · Frozen Fruit, Juice, and Vegetable Manufacturing
When material returns to a process, the usual one-input-to-one-output diagram stops working. A frozen produce plant can show how it preserves the link from a rework bin to a later output lot. FDA uses transformation and traceability records for covered foods. micro1 has advertised workplace video collection that includes food production plants. This proposed sample tests record lineage. Any filming project would need its own scope. FDA food traceability rule FAQs · micro1 workplace recording listing
Use an invented bin, two source lots, and two scheduled pack runs. Provide quantities with consistent units and explicitly record which run received a portion of the bin. Add a log entry that notes an intention to rework the material without evidence that the transfer happened. Ask the model to distinguish scheduled and completed movement, then identify all downstream lots supported by records. Score gaps as gaps.
Keep production recipes, real recall files, and retailer or grower identities outside the packet. A food safety lead should design the fictional sequence and any training photos.
Describe a rework lineage scenario
Original Fiund exercise
Only a completed transfer extends a rework bin's documented ancestry to a later output
An original frozen-produce graph uses fictional source and bin aliases with practice mass units. There is no actual recipe, product, recall, grower or operating instruction.
| Record | Source | What it records |
|---|---|---|
| FPR1 | Bin source map | Practice bin B receives 6 U from source L1 and 4 U from source L2. No component-level split record within B. |
| FPR2 | Completed transfer | Original event moves 5 U from B to pack run P1, which maps to output O1. Transfer explicitly confirmed; no per-source composition of that portion. |
| FPR3 | Scheduled second run | P2/O2 planned to receive another 5 U from B, intention logged only. No executed transfer or other B movement supplied. |
Question for the model
Which output has a documented B contribution, and can the exact L1/L2 split or planned O2 contribution be claimed?
Show the reference answer and checks
FPR1 and FPR2 trace a five-unit B portion to P1/O1 and identify L1 and L2 as documented B inputs. No component breakdown proves the amount of each source in that portion. FPR3 leaves O2 planned-only without a completed B transfer. Preserve source ancestry, verified transferred mass and unknown composition separately rather than assume a proportional split or mark both scheduled outputs as actual descendants. No recall or release finding is made.
- Treating a scheduled rework movement as executed.
- Allocating known bin inputs proportionally to an unmeasured portion or omitting a documented ancestor.
Fields to preserve
- Source lot and rework bin
- Defines input ancestry.
- Completed transfer and output map
- Supports downstream trace.
- Mass basis and unresolved composition
- Limits attribution.
Test another case
Add an independently reviewed component split for the O1 portion only. Require its quantities to resolve without assuming O2 occurred.
Use original synthetic records and approved props. Exclude real plant history and grower details; qualified staff retain food decisions.
Discuss a contribution
Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
