Include receipt and issue of listed materials and components, directly controlled housing work, optical/electronic integration, assembly, calibration, functional testing and saleable packaging through the manufacturing-site gate.

boundary_upstream_inputs
purchased inputs
Link each purchased material, component, battery, electricity and packaging input to a geographically and technologically representative upstream dataset; do not restate upstream emissions as foreground exchanges.
boundary_quality_test
calibration and functional testing
Retain model-specific calibration, functional-test, precision-test and acceptance evidence; identify the applied test procedure and do not represent a partial precision check as comprehensive product acceptance.
boundary_exclusions
default study boundary
Exclude capital equipment, buildings, employee travel, product use, maintenance and end-of-life unless the declared study scope explicitly includes them.

allocation_subdivide_models
multiple instrument models or product families
Prefer model-, batch- or line-level subdivision using BOM, issue, meter and accepted-output records.
allocation_shared_operations
shared electricity and common operations
When subdivision is not feasible, allocate shared burdens using a documented causal driver such as machine time, test time or occupied production time; disclose the driver and perform a sensitivity check against item-count allocation.
allocation_rework_scrap
rework, rejects and recyclable scrap
Assign rework burdens to the accepted output that required them; record any exported recyclable material as a separate waste or co-product exchange and disclose the applied cut-off or substitution convention without netting it from input quantities.

validate_reference_output
reference flow and finished output
Exactly one accepted saleable instrument must be the normalized reference output; rejected, reworked or incomplete units must not be counted.
validate_uuid_identity
UUID-bearing exchanges
Verify each UUID against the declared flow name, flow type, property and unit group; keep the reference-product UUID empty until an exact CPC 48212 instrument flow is confirmed.
validate_bom_completeness
foreground inventory
Reconcile listed and additional atomic inputs to the approved model BOM, packaging BOM, issue/return records and accepted output population; disclose omitted exchanges and cut-off rationale.
validate_electricity
purchased electricity
Reconcile attributable electricity to meter or invoice totals, preserve the allocation driver and verify the 3.6 MJ/kWh conversion.
validate_test_evidence
finished surveying instrument
Confirm that the declared model-specific acceptance evidence exists, identifies the applied test procedure and covers the instrument functions represented by the declared product specification.
validate_range_status
important flows
Do not substitute an external default range for missing foreground data while the manifest records an unresolved range-evidence need.
