Step 4 / Model plan

Datasets & proxies

Resolve inventory flows into traceable LCI datasets, document proxy logic, and keep license boundaries clear before the model run is locked.

Proxy decision rules

Controls used before a weak match can enter the model

2 open
Material proxy threshold

Technology, geography, and temporal coverage must be documented when confidence is below 70%.

Foreground assumption link

Proxy selections keep the source inventory line, supplier note, and reviewer owner together.

Temporal coverage guardrail

Datasets older than five years require either source justification or a sensitivity run.

Evidence and license posture

What can be exported with the study packet

Audit-ready
Allowed in reports

Dataset name, version, geography, source database, match confidence, and proxy rationale.

Never redistributed

Licensed unit process exchanges, provider metadata beyond credentials, and background inventory tables.

Reviewer packet

Foreground assumptions, chosen candidate, rejected alternatives, license state, and evidence links.
