# Single-layer extruded polycarbonate lighting diffusers from complete supplied pellets

## 1. Scope and Applicability

Manufacture a specified indoor-lighting-host single-layer, non-cellular, unreinforced, cut-to-length PC diffuser, starting from purchased complete virgin PC pellet formulation. Include receipt/storage, conveyance, moisture conditioning, screw plastication, continuous die forming, actual sizing/cooling, haul-off/cut-to-length, trimming and clean regrind management, dimensional/optical inspection and first quality release. Include actual utility generation/losses and failed, start/stop, idle, cleanup and rework loads. Record actual subsequent packing/storage/handling/dispatch in separate service accounts. This is complete manufacture, not purchased-finished-part repacking. [condale-pc; condale-manufacture; covestro-pc-2018; ifc-plastics-2007]

Actual Condale PC diffuser/manufacturing capability and Covestro pellet-processing evidence form a transparent technical synthesis, not one SKU, plant, grade, recipe or contemporary order. The UK example does not establish a Chinese factory; the CN medium-voltage identity below applies only at a matching actual utility gate. Predrying has a melt-degassing alternative; retain actual equipment and moisture-control evidence without automatically charging both. Source temperatures, moisture thresholds, dimensions, recipe fractions, density, power, losses, lifetime and performance values are not defaults. [condale-pc; covestro-pc-2018]

Exclude complete luminaires, LEDs/drivers, electrical enclosures, insulating fittings, generic building profiles, formed sheet, other polymers/PC blends, external recyclate, reinforcement/foam, multilayer/UV coextrusion, onsite resin or diffuser-masterbatch compounding, injection moulding, coating/printing, bonding/assembly, and outdoor or medically certified uses. A changed construction needs applicability review and complete actual exchanges; exclusion never permits hiding an actual operation. ET evidence distinguishes outdoor protective layers and component fire tests from resin ratings. CPC distinguishes36960 from36310,36950 and36980 but supplies no substantive manufacturing note; this is only a narrow36960 subset. [covestro-et-2016; un-cpc3-2025]

| excluded_products | Complete luminaires; LEDs and drivers; electrical enclosures; insulating fittings; generic building profiles; formed sheet; other polymers or PC blends; external recyclate; reinforcement or foam; multilayer or UV coextrusion; onsite resin or diffuser-masterbatch compounding; injection moulding; coating or printing; bonding or assembly; outdoor or medically certified uses; actual departures require complete applicability review |
| representative_product | A bare opal/frosted PC diffuser dedicated to its declared lighting host; no fixed brand or dimensions |
| production_route | Complete pellets → moisture control → screw/die extrusion → size/cool/haul/cut → inspect/first release → separately observed supply services |
| market_state | Cooled bare accepted diffuser at first release; packaging and host electrical assembly excluded |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Produce a host-specific PC optical lighting diffuser |
| How much | 1 kg unique newly first-quality-released net bare diffuser mass |
| How well | Actual approved drawing and dimensional optical mechanical surface and host-interface acceptance; no generic lumen or certification equivalence |
| How long or cycle | One manufacturing campaign through first quality release; useful life and lamp electricity not quantified |
| reference_flow_link | first_release |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Parts n.e.c. of lamps, lighting fittings, illuminated signs, illuminated name-plates and the like, of plastics `9fec99da-b5dd-4be9-aa8e-44e0d758f3ba` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | part drawing and dedicated lighting host interface; PC grade and virgin origin; complete supplied formulation and optical finish; linear or branched structure and actual additive declaration; single-layer non-cellular unreinforced construction; actual drying or melt-degassing configuration; die sizing cooling haul-off and cut-length route; dimensional optical mechanical and duty-specific acceptance; actual indoor use restriction and no whole-lamp approval claim; unique first-release cohort and net mass; raw-material WIP FG and equipment-loop stocks; each inherited exchange vector and original cohort denominator; internal regrind genealogy and thermal history; external return direction and original release linkage; observed post-release service interval and carryover; CN medium-voltage import gate and actual losses; water thermal state and supplier water-energy convention; whole preparations and nested constituent ledgers; each package material stock and gross movement ledger; species particle size compartment and independent identification; site period allocation hierarchy uncertainty and completeness |

Every required qualifier must appear in consumer-visible dataset metadata, reference description, process notes or equivalent fields. Q is unique new first-release net kg; same-cohort closing FG is already inside Q, not additional production. Count, length and gross packaged weight do not replace measured net mass; a length conversion requires measured same-configuration linear mass with sampling, conditioning and uncertainty, never density inferred from a native secondary coefficient.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_mass | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Q is unique newly first-quality-released net bare diffuser kg for one configuration/cohort, calibrated weighed after cooling and acceptance excluding detachable tare. cp_release collects raw kg; calc_reference alone divides attributable raw numerators by Q. |
| native_units | all inventory rows | Native reference property | kg or MJ | Mass and energy use their verified native chains. Convert electricity kWh to MJ by3.6 exactly before attribution; energy is not a mass balance term. No count-to-mass or length-to-mass constant is invented. |
| raw_conversion | all inventory rows | Measured extensive quantity | raw units | Whole preparations enter once with assay/carrier subledgers. An already integrated volume is not multiplied by time; integrate only a real rate. Mass from volume requires independently measured substance-specific density at stated temperature/pressure. |
| zero_output | all inventory rows | Raw burden vector | raw units | Retain all failed/start/stop/idle/cleanup/rework burdens for Q=0; preserve unresolved cohort attribution and report no unit result. Reinspection/reshipment never creates Q. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Actual complete virgin unreinforced extrusion-grade PC pellet preparation at receipt with upstream burden and packaging boundary declared |
| starting_condition_role | Purchased material for complete foreground conversion |
| product_classification_scope | Narrow dedicated plastic lighting diffuser subset of36960; not generic36310 stock or whole lamp |
| recursive_input_rule | Purchased finished diffusers retain upstream burden and are outside pellet conversion; qualified old returns retain original release and do not recurse |
| upstream_dataset_requirement | Match complete resin formulation and actual utility packaging transport treatment providers without omitting or duplicating their included burdens |
| disclosure | Site period configuration first-release gate and actual service interval; raw/WIP/FG/equipment-loop stocks with distinct inherited vectors and native restrictions |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| boundary_applicability | all processes | Apply only to a dedicated indoor-lighting-host single-layer non-cellular unreinforced virgin-PC diffuser made from complete supplied pellets and cut to length. Exclude complete lamps/LEDs/drivers, electrical enclosures, insulating fittings, generic building profiles, formed sheet, other polymers/PC blends, external recyclate, reinforcement/foam, multilayer/UV coextrusion, onsite resin/masterbatch compounding, injection moulding, coating/printing, bonding/assembly and outdoor/medically certified use. Actual departures require complete route review and every actual atomic exchange, not hidden zero. | condale-pc; covestro-et-2016; un-cpc3-2025 |
| boundary_source_context | all processes | Industrial sources are qualitative independent technical synthesis, not one SKU/grade/recipe/factory. Condale UK capability does not establish CN manufacture; each utility geography and provider needs actual compatibility. No source processing threshold, dimension, yield, density, unit mass, energy intensity, lifetime or certification is a default. Preserve real drawing and optical/dimensional/mechanical acceptance; a resin fire rating is not a finished-diffuser or whole-luminaire approval. | condale-pc; condale-lighting; covestro-pc-2018; covestro-et-2016 |
| boundary_route | manufacture | Include the complete actual pellet-to-diffuser conversion and all installed utilities. Record actual drying or melt degassing, die/sizing/cooling/haul-off/cut operations and optical rejection. No fuel/steam/boiler, wash plant, abatement train or refrigerant is presumed. Any actual additional operation needs named atomic inputs/outputs and applicability review. | covestro-pc-2018; condale-manufacture; ifc-plastics-2007 |
| boundary_feed | pc_feed | Whole purchased PC formulation crosses once; supplied diffusion additives and stabilisers remain its composition subledger. Actual separate masterbatch mixing changes the route and requires every whole purchased preparation, mixing energy and loss. Internal regrind retains configuration, contamination and thermal history plus each inherited burden vector; never call it new virgin purchase or free feed. | covestro-et-2016; ifc-plastics-2007 |
| boundary_stocks | all processes | Use disjoint raw-material, WIP, FG, water-loop, oil-charge, refrigerant-charge and abatement-stock accounts, each with opening/closing quantity, state and inherited exchange vector. Do not count circulating water or an in-equipment charge again as WIP. Raw-material withdrawals reflect real stock changes. Retain historical cohorts and original denominators; future missing vectors hold a quantitative package. | ilcd-general-2010 |
| boundary_gates | all processes | Manufacturing Q is first quality release once. Same-batch closing FG is inside Q. Post-release service burdens attach to actual serviced cohorts/intervals including stock remaining unshipped; carry opening/closing FG history, gross dispatch and both external return directions. Reinspection creates no production; actual incremental rework attaches once to the original cohort. Consolidation cancels internal Q transfer and every internal recovery without erasing their burdens. | ilcd-general-2010 |
| boundary_water | manufacture | Separate purchased makeup, free feed moisture, in-loop water, condensate, actual evaporation, aqueous waste and external Product returns. Record actual gross received/returned heat-exchange water with temperature/pressure/enthalpy and supplier water/energy agreement. No presumed reaction or hydration/dehydration is inferred from one residual; mass and relevant element balances are independent from species/reaction-water evidence. | ifc-plastics-2007 |
| boundary_species | manufacture | Screen actual SDS/process/outlet evidence for each real chemical and destination. IFC Table4 omits PC; no listed other-polymer species or factor is transferred. Phenol and R134a cards are conditional, not proof of emissions. VOC/COD/TOC and uncharacterised losses remain indicators/uncertainty; add independently identified species and correct compartments individually before quantitative completion. | ifc-plastics-2007 |
| boundary_packaging | all processes | For each single package material: opening empty + opening attached-to-WIP/FG + opening reusable + external acquisition + external returns received = corresponding closing stocks + packages with gross physical shipments + separate external returns sent + waste. Cancel internal reuse; never reduce real outward mass by allocation or reuse. Packaging is not bare diffuser Q, new purchase on reuse, or an automatic coproduct/credit. Keep inlet sacks and each supply-service package separate. | ilcd-general-2010 |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| manufacture | Complete pellet-to-diffuser manufacture and first release | required | Actual complete route and installed operations | Foreground manufacture | per 1 kg reference flow |
| supply_services | Actual post-release supply services and custody movements | required | Actual observed matched-cohort service interval | Separately reported incremental services and physical stocks | per 1 kg reference flow |

Each card is one physical exchange; conditional rows require real presence/absence evidence, and unmeasured never means zero. Add every actual missing material, utility, package, waste and species individually, and reassess changed routes. Cards and collection aggregation point to the same once-computed calc_reference result without another division. Retain gross physical quantities independently; burden allocation does not shrink physical exchanges.

##### Elementary flows

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| allocation_scope | all processes | Use this hierarchy only in a declared attributional inventory when allocation is required. First separate dedicated operations, then subdivide or virtually subdivide using actual process understanding and measurements. Dedicated resin, optical rejects and failed runs stay with their causative cohort. | ilcd-general-2010 |
| allocation_causality | shared exchanges | For each remaining exchange identify the determining physical causal relationship and test why it controls quantity. Extruder load/duration, cooling heat removal and warehouse occupied volume/area with time can differ; a convenient proxy is not causality. No universal mass/time share, fixed allocation ratio or free physical/economic choice applies to all exchanges. | ilcd-general-2010 |
| allocation_residual | genuinely residual multifunctional processes | Only after documenting why subdivision and exchange-specific determining causality cannot resolve a real residual, use contemporaneous quantities times market value at the same common-process gate and actual supplied condition. Derive gate values by removing downstream conditioning, packaging, transport and trading contributions. Unknown/non-positive prices, uncertain cofunction status or missing measurements require review, not automatic allocation. Retain sensitivity and uncertainty. | ilcd-general-2010 |
| allocation_recovery | internal and exported recovery | Carry internal regrind and reuse burdens and cancel internal transfers. Independently establish waste, treatment-service or product status of each external stream; sale does not grant avoided-virgin credit. Physical balances use unallocated real quantities and never allocated burden shares. Exported recovered-product methodology needs separate review. | ilcd-general-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.

Collect unnormalised observations first. aggregation_rule labels the final destination basis only and performs no arithmetic. calc_units handles original units/rates, calc_attribution handles assignment and inheritance, and calc_reference divides by Q once. Historical service cohorts keep their original Q and vectors rather than renormalising against current production.

| cp_waste | manufacture | Each actual waste stream and treatment destination | raw foreground record | stream identity; state; net weight; wet dry basis; assay; treatment; date; internal versus external; reject cohort | Weigh segregated streams and reconcile treatment receipts and retained contained substances without direct-emission double count | kg | Each actual movement or meter interval and stock boundary | Complete campaign plus observed service interval including zero-output records | Actual site line configuration and original cohort | per 1 kg reference flow | Calibration source records full stock/vector reconciliation and uncertainty |
| cp_emissions | manufacture | Each identified chemical and receiving compartment | raw foreground record | species identity; CAS if identified; particle size; outlet compartment; sampling time; concentration; actual rate or integrated volume; temperature pressure humidity; detection uncertainty; abatement and charge evidence | Independently identify chemical and compartment; convert sampling units before integrating real rates. Reconcile each actual destination; indicators and unexplained residuals do not become species masses | kg per species before reference division | Each actual movement or meter interval and stock boundary | Complete campaign plus observed service interval including zero-output records | Actual site line configuration and original cohort | per 1 kg reference flow | Calibration source records full stock/vector reconciliation and uncertainty |
| cp_release | manufacture | Unique first release and net diffuser mass | raw foreground record | configuration; host drawing; lot; unique release ID; cooled net mass; gross and detachable tare; actual optical dimensional mechanical tests; prior-release flag; rework genealogy | Calibrated weighing after acceptance; deduplicate first-release IDs against old FG and returns; retain failures and sum only unique newly released bare kg into Q | kg | Each actual movement or meter interval and stock boundary | Complete campaign plus observed service interval including zero-output records | Actual site line configuration and original cohort | per 1 kg reference flow | Calibration source records full stock/vector reconciliation and uncertainty |
| cp_packaging_in | manufacture | Resin sack custody and waste separately | raw foreground record | material; tare; opening closing empty attached reusable stock; external receipt; external return received; return sent; waste; upstream included burden | Weigh actual sack movements and confirm supplier-packaging boundary; maintain complete package identity and no overlap with polymer net mass | kg | Each actual movement or meter interval and stock boundary | Complete campaign plus observed service interval including zero-output records | Actual site line configuration and original cohort | per 1 kg reference flow | Calibration source records full stock/vector reconciliation and uncertainty |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| calc_units | all inventory rows | Convert original units before attribution: electricity MJ = 3.6 times measured kWh; mass from volume uses independently measured substance/state density. Integrate only real rates once; already integrated volume is not multiplied by duration. Retain original observations and uncertainty. | raw_observations; native_units; measured_density; actual_rates | converted_raw |  |
| calc_release | first_release | Q = sum of unique newly first-quality-released net bare diffuser kg in cp_release for the declared configuration/cohort. Closing FG of that cohort is already within Q; old returns and reinspection/reshipment add no new Q. | cp_release; configuration; cohort | Q | condale-pc; condale-lighting |
| calc_attribution | all inventory rows | A_i is the attributable unnormalised amount of row i after unit conversion, disjoint raw/WIP/FG and equipment-loop opening/closing stock/vector reconciliation and internal-transfer cancellation. Retain failed/idle/cleanup/rework loads. Apply section7 exchange by exchange only where shared. Real physical custody outputs remain gross quantities; no burden allocation reduces their mass. Supply-service A_i is incremental for its observed cohort interval; old cohorts retain original Q and per-exchange history. | converted_raw; opening_vectors; closing_vectors; allocation_evidence; internal_transfers; cohort_history | A_i | ilcd-general-2010 |
| calc_reference | all inventory rows | x_i = A_i / Q for Q>0, exactly once. A_i is this row attributable raw amount in its stated unit from calc_attribution; Q is first-release kg from calc_release. Cards and aggregation only reference this same stored result per1kg reference flow. For Q=0 retain raw burden without a unit result. Historical cohorts use their original Q, never the current campaign denominator. | A_i; Q; calc_attribution; calc_release | x_i |  |
| calc_physical | all processes | Close unallocated manufacturing mass: opening WIP + each actual material withdrawal + opening disjoint in-process water/oil/refrigerant/carbon stocks = Q + closing WIP + closing disjoint stocks + all actual external outputs/losses. Raw-material stores reconcile separately. FG: opening FG + internal new-Q handover + external returns received = closing FG + gross dispatch + separate outward returns + actual FG waste/loss. Consolidation cancels the internal Q handover and recovery; energy is no mass. Do not add same-batch closing FG to manufacturing Q. Independently check relevant element/species balances and measured moisture with uncertainty; one residual cannot solve two unknowns. | cp_material; cp_water; cp_aux; cp_waste; cp_emissions; cp_release; cp_fg | unallocated_physical_balances |  |
| calc_packaging | all processes | Apply boundary_packaging separately to each material and inlet sack; preserve actual gross outward and both external-return directions before attribution. Account attached WIP/FG packages and reusable stocks once. Internal reuse cancels; only external acquisitions incur a new purchase, subject to provider already-included boundaries. | cp_packaging_in; cp_packaging; cp_fg | package_material_balances |  |
| calc_quality | all inventory rows | Retain source identity, measurement uncertainty, non-detect limits, stock history and applicable provider restrictions. Unknown chemical fate, missing inherited vectors or core route/reference inconsistency blocks a completed quantitative package; do not invent zeros, default density, fixed losses or assumed compliance. | raw_observations; uncertainty; cp_release; cohort_history | quality_disclosures |  |
| 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 | Inspect full native identity including every name qualifier comment CAS type property reference index and all geography; do not substitute chemical species or particle compartments by a matching word. Use official zh baseName for selected UUIDs. | Verified identity chain and actual provider compatibility |
| dq_coverage | all processes | Cover full matched campaigns and actual services with start/stop idle failed cleanup and rework; no favourable-run sampling or hidden unlisted totals. Keep zero-output and absence evidence distinct. | Logs meters BOM and rejected-lot records |
| dq_stocks | all processes | All disjoint raw WIP FG water-loop and equipment-charge stocks carry their own state and every inherited exchange vector without overlap; old cohorts retain original denominators and returns history. | Opening closing reconciliations and cohort genealogy |
| dq_speciation | manufacture | Use independent substance/destination evidence; mass/element residuals, COD or VOC are not a licence to infer individual chemicals or reaction water. No universal source emission factor or numerical screening threshold. | SDS sampling reports detection and thermal-state uncertainty |
| dq_applicability | reference product | Product-level drawings and actual optical/mechanical/duty acceptance govern use; resin rating or manufacturer capability never proves final diffuser or luminaire certification, lifetime or luminous equivalence. | Actual qualified release evidence and restrictions |
| dq_uncertainty | all inventory rows | Disclose time geography process gate allocation sensitivity missing UUID/provider and measured uncertainty separately; ordinary future site quantities do not become invented numbers. | Traceable data lineage and explicit completeness statement |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| validate_basis | all inventory rows | Verify explicit first_release Product output link and1kg declared net first-release basis in both languages. Check raw units then attribution then the only A_i/Q operation, Q=0 retention and historical denominator preservation. | condale-pc |
| validate_route | reference product | Require actual complete PC pellet-to-lighting-diffuser route and product acceptance. Purchased finished part repacking, enclosure proxy, changed layer/material or unproven core terminal identity fails applicability; review actual changed operations completely. | condale-pc; covestro-pc-2018 |
| validate_identity | all inventory rows | Every adopted UUID requires compatible full flow and exact property/unit-chain evidence, including geography and media. Specific unresolved auxiliaries remain measured and tracked individually; no generic collection substitutes. Apply all native restrictions in each card. |  |
| validate_balances | all processes | Close independent unallocated raw/WIP/FG and equipment/water/charge accounts, each package material and each real external destination; preserve inherited vectors. Never close with allocated quantities, duplicated FG or unexplained species/reaction-water residuals. |  |
| validate_completeness | all processes | Retain all failed idle cleanup rework zero-output and conditional presence/absence evidence. Unknown core identity/route/basis or missing real species/history holds the quantitative package; ordinary auxiliary UUID gaps do not authorise omission. Engineering checks do not approve science, translation, classification mapping or publication. | ilcd-general-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. |  |
