7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_scope	all inventory rows	This method uses attributional allocation only where the study situation requires allocation. Establish that scope first; industrial manufacturing sources do not authorize a consequential substitution or automatic recycling credit. Respect applicable ILCD situation/recycling provisions when a different question is asked.	jrc-ilcd-2010
allocation_exclusive	all inventory rows	First subdivide actual distinguishable stages/lines or use evidenced virtual subdivision. Assign each whole formulation, dedicated machine meter, test, failure, cleanup, package and FG service directly to its causing lot/product when possible. Retain burden-bearing stock transfers and shared idle loads; no total-output shortcut before exclusive attribution.	jrc-ilcd-2010
allocation_causality	all inventory rows	For each still-shared exchange independently identify the determining physical cause and actual measured driver, e.g. heater duty with temperature/time/configuration, cooling duty with measured flow/enthalpy, or handling with actual operations. Mass/count alone is not universal causality. Validate each driver and allocation total/uncertainty; different exchanges may need different causal drivers.	jrc-ilcd-2010
allocation_residual	all inventory rows	Only the genuine residual lacking a determining physical assignment uses relative market value of actual cofunctions at the common process exit/entry gate in their real state and period. Derive same-gate values transparently by removing later transport/conditioning/packaging costs where necessary; record quantity, currency, date and sensitivity. Unknown causal/value evidence holds that dataset incomplete; no fixed ratio or free choice between physical/economic keys.	jrc-ilcd-2010
allocation_returns	all packaging rows; fg_out; fg_return; waste_fg	Physical custody remains unchanged by burden allocation. Internal reuse carries inherited burden once; external waste/recovery follows actual treatment/ownership and applicable recycling model. No automatic negative flow, avoided virgin credit or erasure of old cap production from a return, retest or lost lot.	jrc-ilcd-2010
asset_manufacture_conservation	existing capital/reusable manufacture attribution	Within the applicable allocation decision context, original manufacture burden attributed across uses of actual capital equipment or reusable articles already included in foreground production, packaging or observed services uses one persistent same-asset ledger across all crops, products, cohorts, manufacturing/postrelease services, owners and observation periods. D is its supported whole installed service: all realized historical service plus supported remaining service in the same units as actual beneficiary use u; D must be finite and positive. Period capacity, remaining-only capacity, the physical asset/article mass alone, or current-period product Q alone is not D; supported whole-service throughput in mass units may be used when it demonstrates the causal service and matches u. This does not amortize the manufactured reference product over downstream life or change its declared reference gate/Q. The fractions u/D and all previously assigned manufacture shares together must never exceed 1. Changes of window, custody, provider or repair never restart the original manufacture balance. Replacements have distinct identities and only their real new manufacture vectors; actual repair and treatment increments remain separately accounted. Revised capacity evidence requires transparent reconciliation of prior shares and sensitivity, not a fresh ledger. Keep full physical mass and stock movements independent of burden shares. Unknown D, prior shares or beneficiary coverage requires review and no final manufacture-attributed amount; no assumed lifetime, utilization, zero or arbitrary division is permitted. For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

8. Foreground Data Collection, Calculation, and Quality Rules

Data Collection Protocols

For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
convert_raw	all inventory rows	Convert calibrated raw values to the declared atomic numerator unit before attribution; integrate only actual rates once. Use independent material state/density/composition, never a screening property coefficient. Preserve original records and uncertainty.	raw_value; raw_unit; interval; measured_state; density; composition	raw_numerator
quality_quantity	released_cap	Q = sum of unique new first-accepted net complete-cap kg; exclude packaging and previously released lots. No delivery or reinspection count enters Q.	cp_quality; accepted_lot_mass; first_release_id	Q	jerry-swim-cap-production
stock_vectors	all inventory rows	By each actual raw/WIP/loop/equipment lot conserve physical amount and every inherited exchange vector: opening plus real increments/transfers equals closing plus actual exits/consumption; preserve source cohort denominator and eliminate overlapping stock accounts.	cp_material; cp_water; cp_charge; opening_vector; current_increment; closing_vector	attributed_lot_vector
exchange_attribution	all inventory rows	Exclusive/virtual subdivision precedes exchange-specific determining physical causality; only the genuine remaining shared residual uses same-period actual common-gate market values. Preserve Q=0 loads for explicit burden transfer/disclosure, not arbitrary future amortization.	raw_numerator; attributed_lot_vector; causal_driver; residual_gate_value	A_i	jrc-ilcd-2010
fg_cohorts	fg_in; fg_return; fg_out; fg_power; waste_fg	Retain original manufacturing A_i and original Q for old FG/returns; add only measured attributable incremental service numerator to the same cohort. Reconcile physical FG gate and original dispatch reversals independently; do not allocate old-cohort services onto unrelated current Q.	cp_fg; cp_fg_energy; original_numerator; original_Q; actual_service_increment	cohort_A_i; cohort_Q
pack_balance	all packaging rows	Apply the full boundary_pack equation to each whole physical article independently; keep all actual external directions at measured gross article mass and internal reuse cancelling only inside custody. Burden allocation cannot alter physical movement.	cp_pack; article_stock; article_purchase; return_received; gross_outward; return_sent; article_waste	article_balance
species_balance	all elementary rows	Close total mass/elements and independently measured actual species/phase balances, including carrier gas and separate external water/equipment stocks. Never fit multiple unknown species to one residual or convert COD/TVOC to a specific chemical.	cp_species; cp_air; cp_water; cp_charge; independent_assays	species_balance	wacker-silicone-processing
report_once	all inventory rows	q_i = A_i / Q, once for the identified new first-release cohort after raw conversion, attribution and inherited-vector reconciliation. For old cohorts use their own cohort_A_i and original cohort_Q in this same operation. Q=0 retains loads and produces no unit result. Reference output is 1 kg by definition; cards and aggregation only refer to this operation.	A_i; Q; cohort_A_i; cohort_Q	q_i
asset_manufacture_share	existing capital/reusable manufacture attribution	For each included original asset manufacture vector B, f_current = u_current / D only after the persistent ledger verifies the supported whole installed-service denominator, all beneficiaries and prior assigned shares. Attribute f_current * B once to the actual beneficiary before the existing single reference normalization. Check prior_shares + all current/new beneficiary shares <= 1; carry the remaining original balance. Capacity revisions reconcile the historical ledger. Full physical asset/packaging mass and actual gross stocks/returns never receive f_current. Unknown D or history leaves the final attributed result unavailable, without suppressing actual repair/replacement/service burdens.	asset_id; original_B; u_current; D; historical_beneficiaries; prior_shares; capacity_evidence	conserved attributed manufacture vector

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity	all inventory rows	Match whole preparations/grades, complete native names/qualifiers/CAS/geography/type/all properties/reference units and actual provider. Empty auxiliary UUIDs need identity resolution; generic family records never override a hard chemical/form/route contradiction.	Supplier/native originals and compatibility measurements
dq_complete	all inventory rows	Retain all three physical gates, whole preparations, raw/WIP/FG and separate loop/charge stocks with every inherited exchange vector; include all failed/idle/rework events, actual species and package directions.	Full stock and operating-period reconciliation
dq_basis	all inventory rows	Use unnormalized raw numerator records and only report_once for the matching actual Q; original old-cohort denominators persist. No fabricated weight, density, threshold, emission factor, ratio, life or activity range.	Calibrations original units formulas and cohort history
dq_scope	all processes	Primary manufacturer capabilities and supplier guide are independent technical synthesis, not same-SKU factory evidence. No source marketing rates or grade-chart values become cap defaults; qualify actual site/period and uncertainty.	wacker-silicone-processing; jerry-swim-cap-production; ukong-swim-cap-supply
dq_missing	all processes	A real missing terminal, route or basis prevents an authored method claim; a critical missing measurement/species/history makes the concrete dataset incomplete. Ordinary auxiliary UUID/provider/future factory-data requirements alone do not imply an invented numeric result or universal scientific approval.	Explicit missing-data and uncertainty register

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference	released_cap	Require the actual complete unprinted nonprotective LSR cap and every qualifier; 1 kg net new first-release basis must select this sole linked reference row in both languages. Do not infer per-cap weight or let generic native headgear identity replace route evidence.	jerry-swim-cap-production; ukong-swim-cap-supply; un-cpc3-2025
validate_measurement	all inventory rows	Verify raw units/rates and measured state, unique Q, whole formulation count, complete stock vectors and original cohort denominators; report_once executes once only. Q=0, unsupported conversion or missing critical relationships cannot yield a passing concrete dataset.
validate_physical	all processes	Independently reconcile manufacturing, FG and combined physical mass/elements, actual species/phase data, separate water/equipment charges and every package article/direction; cancel only internal transfers. Do not solve two unknowns from one residual or erase gross dispatch through reuse/allocation.
validate_native	all inventory rows	Adopted Product/Waste/resource/emission type, CAS, material state, particle structure, supply geography/voltage and actual compartment must agree with original native restrictions. Distinguish ordinary air from long-term/indoor/water outlets; a family name or taxonomic correction is not compatibility proof.
validate_allocation	all inventory rows	Demonstrate exclusive/virtual subdivision and per-exchange determining physical cause before any genuine residual common-gate market-value allocation. Preserve exact full-period failures, zero-output and historical stock burdens; missing evidence stays explicit.	jrc-ilcd-2010
validate_quality	released_cap	Require actual geometry/visual/fit/cure and declared strength acceptance, A/B storage compatibility and real finishing/postcure evidence. No performance, certification or lifetime can be inferred from a manufacturer page or a supplier example chart.	wacker-silicone-processing; jerry-swim-cap-production; ukong-swim-cap-supply
validate_asset_manufacture_conservation	existing capital/reusable manufacture attribution	For every included capital/reusable manufacture attribution verify same-asset continuity, whole installed service in matched units, all historical/current beneficiaries, prior assigned manufacture shares and cumulative share <= 1. Reject a reset by period, cohort, provider, owner or repair. Check distinct real replacement and incremental repair/treatment vectors separately and preserve gross physical mass. A missing denominator, unexplained previous allocation or incomplete beneficiary ledger requires explicit review and an unavailable final attributed amount; structural inspection cannot claim empirical completeness.
