A_i is the raw exchange numerator after actual unit/rate conversion, attribution and inherited WIP/cohort corrections; Q is kg of newly first-released caps in the selected release cohort. Execute once only for Q>0. Manufacturing and observed service contributions are identified separately; every card and aggregation references this same result. released_cap is the 1 kg identity, not another division.	A_i; Q; cp_release	a_i	jrc-ilcd-2010
release_gate	released_cap	Q = sum of unique first-released new-unit net mass in kg under cp_release. Where counts are used, configuration-specific measured cap mass converts count to kg; preserve its sampling scope and uncertainty. Already released FG, repeat tests, physical returns and dispatch are not new Q.	first_release_net_mass; accepted_new_count; measured_cap_mass; cp_release	Q	bericap-hdpe-cap
raw_conversion	all inventory rows	U_i = raw readings converted to the row unit before attribution. Weighed kg needs no density. Integrated volume times independently measured same-substance/state density yields kg; genuine volume rates are integrated first. Hydraulic m3 retains its volume identity; physical kg subledger is separate. Electricity E_MJ = 3.6 times metered E_kWh; heat and electricity stay separate. No time multiplier on integrated readings and no implicit item mass.	raw_reading; raw_unit; actual_rate_intervals; actual_density_state; cp_material; cp_energy; cp_water; cp_species	U_i	ifc-plastics-2007
wip_vector	manufacture	For each exchange i, A_i_manufacture = opening_WIP_i + opening_separately_held_i + current_new_assigned_U_i - closing_WIP_i - closing_separately_held_i - independently_evidenced_distinct_assignments_i. Separately held vectors cover raw supplies, installed items, cooling/other water, hydraulic fluid, solvent and refrigerant charges where actually present, with physical quantities reconciled independently. current_new_assigned_U_i includes only newly incurred external-receipt and process-load vectors before these stock corrections; internal withdrawal is not an additional purchase. If a directly measured consumption vector already includes a particular stock correction, prove equivalence and apply that correction once only. Keep actual manufacturing losses and waste-treatment burdens in the intended cap cohort, not subtraction credits. Disjoint WIP/non-WIP ownership prevents duplicate stock terms; historical charge depletion without makeup retains its inherited burden. Failed/zero-output pools and later assignment history remain; mass alone cannot invent an exchange vector.	opening_WIP_vector; opening_separately_held_vector; current_new_assigned_U; closing_WIP_vector; closing_separately_held_vector; distinct_assignments; cp_material; cp_water; cp_wip; cp_allocation	A_i_manufacture	jrc-ilcd-2010
fg_vectors	fg_service	For each release cohort preserve its original released exchange vector and original Q. Opening inherited FG vector plus internal Q receipt vector plus actual returned vector plus current attributable service vector equals closing FG vector plus gross outward vector plus discarded/treatment vector plus any independently evidenced emissions. Physical returns and original-delivery reversals are distinct signed records. Service burdens for historical cohorts use their own original cohort, never unrelated current Q; observed services do not reset manufacturing burden.	opening_FG_vector; Q_receipt_vector; returned_vector; current_service_vector; closing_FG_vector; gross_outward_vector; discarded_vector; cp_fg	A_i_service and reconciled cohort vectors	jrc-ilcd-2010
physical_gates	all inventory rows	Manufacturing mass: opening material/WIP/auxiliary-fluid stocks + external material inputs = closing stocks + Q + external return/waste/emission masses. Internal regrind cancels. Cap-only FG mass: opening FG + Q + physical cap returns = closing FG + gross cap departures + discarded caps + any confirmed cap-derived emissions. The combined gate cancels the internal Q pair: opening manufacturing+FG stocks plus external material inputs and cap returns = closing manufacturing+FG stocks plus gross cap departures and real external return/waste/emission masses. Package balances are checked separately then included once in the combined all-material gate. Q is not added again beside its closing FG.	opening_material_WIP_FG_stock; external_material_inputs; Q; cap_returns; closing_material_WIP_FG_stock; gross_cap_departures; external_mass_exits; cp_wip; cp_fg; cp_water; cp_waste	independent manufacturing FG and combined mass closures	ifc-plastics-2007; jrc-ilcd-2010
package_balance	cp_pack; cp_supply_pack	For each physical packaging form k: opening_empty_k + opening_attached_WIP_k + opening_attached_FG_k + opening_reusable_k + purchased_k + external_returns_received_k = closing_empty_k + closing_attached_WIP_k + closing_attached_FG_k + closing_reusable_k + gross_carried_outward_k + returned_to_external_owner_k + waste_k. Internal reuse transfers cancel, and its real service loads remain. Split different forms/materials; exclude package mass from cap Q and never net gross package carriage against returned cap mass.	opening_package_states; purchased_packages; external_returns_received; closing_package_states; gross_carried_outward; returned_to_external_owner; package_waste; cp_pack; cp_supply_pack	each package-form physical closure	sacmi-ccm-2018; jrc-ilcd-2010
species_and_elements	cp_species; cp_water	Quantify each real species/phase independently and retain gross physical transfer separately from net environmental transfer after matched measured ambient-carrier cancellation; evaluate elemental input/output vectors from actual composition/analysis separately from total mass. Measured water supply/storage/return/blowdown/drift/leak/vapour terms share one coherent water gate. At most one unidentified scalar can be constrained by one independent residual; more unknowns require more measurement and remain incomplete. No deliberate reaction water in this non-reactive nominal route.	species_measurements; composition_assays; independent_elemental_data; water_path_measurements; cp_species; cp_water	species phase and elemental reconciliations	ifc-plastics-2007
exchange_allocation	all inventory rows	For exchange i first assign exclusive/subdivided/virtually subdivided U_i. Apply supported determining physical drivers only to its residual shared pool. Only its truly remaining pool uses contemporaneous actual same-gate market values after documented earlier-step infeasibility. Sum all cohort/product/service assigned exchange vectors to the original pool before normalize_once; no fixed allocation fraction.	U_i; exclusive_assignments; residual_shared_pool; physical_drivers; actual_gate_values; cp_allocation	A_i	jrc-ilcd-2010
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	Verify full actual supplier/form/state and all adopted native restrictions; preserve missing auxiliary identity/provider as a data gap rather than a new generic bundle.	Direct identity context plus current supplier PDS/SDS/composition and exact support chain
dq_measurement	all inventory rows	Preserve raw originals, original units/rates, calibration, independent substance-state densities where needed, detection limits and uncertainty; do not substitute an indicative brochure coefficient for measurement.	Instrument files; laboratory and mass/energy/water reconciliations
dq_scope	all inventory rows	Cover the entire selected cohort and time/geographic scope, including failure, start-stop, idle, cleaning and rework. Report measured absence versus unknown and the observed service closing date; future service loads are not fabricated.	Mode logs; cohort/period genealogy; completeness and exclusions register
dq_stocks	cp_wip; cp_fg; cp_pack; cp_supply_pack	Retain per-exchange inherited vectors as well as mass for all opening/closing stocks and returns; reconcile all three physical gates and each packaging form independently of allocation.	Signed physical stocktakes; vector ledgers; package-form closure
dq_sources	all inventory rows	Maintain source id/type/reference/used_for and rule source links with complete applicability/countercontext. Qualitative primary facts are not quantitative site records or scientific/translation approval.	Full primary context; protocol records; unresolved-method and supplier-data disclosure

9. Validation Rules

rule_id	applies_to	rule	source_ids
v_identity	all inventory rows	Check every scope/qualifier and full native name, route, state, geography, CAS where present, type, receiving medium and reference-property support. Cap UUID is CN at-plant production mix for a cap/pump/sprayer family: use only the one-piece cap subset, never proof of HDPE grade, compliance or a provider. HDPE granulate UUID is slurry/gas-phase at-plant mass identity with no CAS/grade; disclose its inconsistent CPC34170 label without treating that label as physical evidence. Reject any real contradictory CAS, particle form or route.	ifc-plastics-2007
v_q	all inventory rows	Verify cp_release, one explicit reference link released_cap, Q deduplication and one normalize_once operation. Reconcile WIP exchange vectors, failed/zero-output loads and all actual unit conversions before normalisation. Repeat release/dispatch cannot increase Q. Q<=0 or missing critical measured relations prevent a defensible unit result and remain explicit incomplete data.	jrc-ilcd-2010
v_gates	all inventory rows	Reconcile manufacturing, FG and combined physical control volumes independently of allocation. Cancel internal release/regrind transfers. Current closing FG is contained in Q, not Q plus another product. Every physical and inherited burden remainder must have an identified stock, discharge, waste or independently assigned service destination. Actual return-repair load belongs to its original released cohort/service; no new production from reinspection.	jrc-ilcd-2010
v_species	all inventory rows	Compare total mass and relevant elemental closure with independently quantified species/water pathways. No residual-fitted chemical emissions; no COD/VOC-to-species invention. Retain unknowns, detection limits, uncertainty and unresolved sinks separately. Confirm actual environmental medium; water-vapour UUID means ordinary unspecified-air emission, not stratospheric or long-term release.	ifc-plastics-2007
v_packaging	all inventory rows	Check each packaging identity/form/stock balance in cp_pack including empty, attached and reusable stocks; gross outward packages follow actual gross carriage, not net cap delivery. No internal reuse repurchase or packaging mass in cap Q. Distinguish one whole commercial tape/carton article from duplicate backing/adhesive/constituent purchases.	jrc-ilcd-2010
v_applicability	all inventory rows	Check resin use conditions and cap test plan independently of broad identities. MB5568 historical PDS supports a water-cap injection route, but typical values and its customer-test disclaimer do not certify a current final cap. MB5569 explicitly not recommended for bottled water cannot be substituted by name similarity. BERICAP geometry, Husky injection architecture and SACMI downstream operations are a transparent synthesis, not a proven same-SKU line. Missing ordinary provider/auxiliary data are disclosed; a genuine core product/terminal/method gap holds methodology as draft.	bericap-hdpe-cap; borealis-mb5568-2017; borealis-mb5569-counter; husky-hycap4-2016; sacmi-ccm-2018
v_data	all inventory rows	Require source-specific primary context, raw readings, calibration, coverage, all reported source fields and uncertainty. No missing exchange is zero; unavailable auxiliary identity is not permission for a collection row. Preserve distinct foreground measurement, author protocol, external process fact and identity evidence. Confirm bilingual rules and generated projection retain all conditions and ancestors; engineering success is not science, translation, mapping or publication approval.	jrc-ilcd-2010
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.
