ATLAS / FIELD NOTES
Better questions make better material records.
Practical guides for the people recording a lot and the people relying on its history. Written around physical events, evidence and the limits of what a record can prove.
01 / OPERATIONS
At the plant
Record the material that arrived, what happened to it and the evidence behind the account.
Material lot traceability: a practical starting point
How to build a useful material lot record from identity, events, evidence and handoffs instead of relying on one certificate.
How to record a material transformation
A practical record of process inputs, outputs, quantities and evidence that does not hide losses or unknowns.
Traceability through blends without false precision
How to document blend inputs and outputs while being honest about source allocation and uncertainty.
Connecting an assay to the right physical lot
A checklist for linking laboratory results to samples, lots, methods and review status.
Recording a material receipt discrepancy
Keep the supplier's declaration and receiver's observation separate when quantities or identities do not match.
Correcting material records without erasing history
How versioned corrections and supersession keep material evidence auditable across company handoffs.
02 / BUYER PRACTICE
Beyond the plant
Ask for useful upstream evidence, understand exceptions and identify potentially affected lots.
Battery-material supplier evidence: a buyer's checklist
A practical checklist for asking suppliers what a material claim covers and which lot-level records support it.
Questions to ask about upstream material traceability
Questions a downstream materials team can use to test the usefulness of a supplier's lot history.
How to find affected downstream lots
Trace an upstream issue through transformations, blends and company handoffs without hiding uncertain branches.
What belongs in a material handoff package?
A field guide to sharing selected lot identity, history, quantities and evidence between companies.
Chain of custody versus material lineage
Why knowing who held a consignment is different from knowing which inputs became which outputs.
How to assess missing or conflicting material evidence
A practical way to separate absent, disputed and superseded evidence in a supplier lot history.
These guides are operational reference material, not a certification, legal interpretation or claim that any supplier's material has been verified. Crucible's hosted three-company handoff is still in pilot development.
