Every rule in this record is conditional on the complete product/route/function limits in §1 and the native identity restrictions in each card.

This PCR covers attributional manufacture of a complete non-electric toilet-seat set: unfilled PP-homopolymer injection-moulded seat ring and lid, conventional non-damped pivot hinges, actual bumpers and declared bowl-fixing parts. It covers raw supplied resin through actual preparation, moulding, cooling, demoulding, trimming, eligible regrinding, assembly and first quality release. Subsequent actual packaging, warehouse, handling and dispatch remain a separately identified release-cohort service account. It excludes baths, basins, pans, cisterns/valves, ceramic fixtures, UF compression mouldings, wood-filled or foamed shells, coatings/printing, soft-close dampers, bidet/electronic functions and bought-finished-set repacking. Other PP copolymer, filler or multi-material structural routes require separate substantiation. The broad native sanitary-flow name does not widen these conditions.

Native sanitary identity is manufactured plastic ware/production mix at plant/Mass only, without fixed CAS, polymer grade, geometry, route, performance, life or geography. Raw PP CAS9003-07-0 is physically consistent but native classification34740 is defective and fixes no grade/form/geography. Adopted identities retain actual configuration, delivered formulation and provider limits in each card; they establish no background inventory or certification.

1. Scope and Applicability

The industrial sources establish complementary product and unit-operation facts, not one common SKU, factory or order. AGI/primary seat manufacturers establish a real sanitary endpoint; IFC supplies general non-reactive plastics process context; Glasfil provides grade-dependent trial counterevidence. Foreground records must establish the actual configuration and operating values. No source test number is prescribed as a load, service-life or conformity certificate.

How much	1 kg net mass of complete sets newly first-released at the factory gate; retain actual accepted set count and measured set masses as supporting data
How well	Actual drawing/BOM and load/chemical/function checks for the declared configuration; neither generic flow identity nor another manufacturer trial certifies performance
How long or cycle	One manufacturing cohort through first quality release; use-stage life is separately declared only from evidence
reference_flow_link	finished

Field	Value
Reference amount	1
Reference product flow	Baths, wash-basins, lavatory pans and covers, flushing cisterns and similar sanitary ware, of plastics `1863571e-49b3-4182-a213-506c1f521d59`
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	PP homopolymer supplier grade and complete delivered additive formulation; seat and lid geometry plus bowl mounting dimensions and actual drawing revision; hinge material and configuration plus bumper/fixing BOM and included loose fitting kit; unfilled nonfoamed uncoated non-electric non-damped route exclusions; declared load and chemical-resistance specification plus test method and actual result without unearned certification; first-release cohort and unique configuration acceptance status; net complete-set mass measurement and accepted count reconciliation; site geography period production technology and utility supply state; opening/closing WIP and FG with per-exchange inherited burden vectors; internal regrind identity and contamination suitability evidence; cohort-linked subsequent service window and original dispatch/return reversal; packaging components gross shipment inventory and return ownership; use duration or cycles declared only when supported; no durability equivalence from mass

All required qualifiers must appear in dataset metadata, process notes, reference-flow comments or equivalent fields. The broad native article name fixes no polymer, geometry, geography or performance; its use is confined to the §1 PP set. Actual count and measured net mass of the same complete configuration support reconciliation, with no fixed kg per item.

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	The basis is 1 kg net complete first-released set mass excluding all transport packaging; cp_release weighs actual complete configurations and reconciles accepted counts. This PCR supplies no per-set mass.
raw_units	all inventory rows	Actual exchange property	actual exchange unit	Collect raw totals and original units. Integrate only true rates; do not multiply integrated amounts by duration again. Complete actual composition/unit/state conversions before allocation, then use the one stored normalization result from §8.
q_zero	all inventory rows	Mass	kg	Q=0 preserves all real raw burdens, stock, failed runs and service ledgers and yields no unit result. Unknown values cannot be called zero or passed.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Actual received PP homopolymer pellets with supplied stabilizers, actual colour masterbatch if used and separately supplied configured components; receipt/transport and upstream burdens retained
starting_condition_role	Full foreground converter manufacture from supplied materials; not purchased-finished-set packaging
product_classification_scope	Only §1 subset within CPC3.0:36930; mapping acceptance is external to this record
recursive_input_rule	Purchased same-category seat sets cannot replace resin-to-article manufacture. Returned already released sets stay in original-cohort service; internal regrind is a burden-carrying transfer, not a new purchased seat or new Q
upstream_dataset_requirement	Compatible actual grade/form/state/geography/time provider for each entire supplied input and transport; disclose packaging inclusion and component BOM, no presumed inventory from flow identity
disclosure	Actual route, utility state, full operation map, configuration, Q gate, cohort/WIP/FG vectors, service window, upstream coverage, allocation and unresolved quantities

rule_id	applies_to	rule	source_ids
`b_complete`	manufacture	Include receipt and inbound movement, dosing, actual moisture/temperature conditioning, mould heating and all injection/cooling/ejection cycles, trimming, in-process inspection, eligible regrinding, assembly and destructive/final testing. Retain failed runs, zero-output campaigns, start/stop, idle and cleanup. A bought complete seat may not stand in for these operations.	`ifc-plastics-manufacturing-2007`; `ziax-seat-manufacturing-2025`
`b_inputs`	all inventory rows	Count each whole supplied preparation/assembly once. Assay, carrier water, embedded materials and active ingredients are subaccounts. Actual in-house formulation uses each purchased constituent, mixing energy and loss. Require compatible provider coverage including raw polymerization, components and inbound transport. No cut-off is established by a missing UUID or missing meter.	`ifc-plastics-manufacturing-2007`
`b_q_gate`	finished	Q is the sum of actual net kg of uniquely first-released complete configurations in the cohort period. Released closing FG is already part of Q and is not an additional manufacturing output. Shipping, reinspection, returned-set repair and internal reuse do not create Q. Unreleased ring/lid parts remain WIP. No fixed single-set kg, assumed density or source-derived test weight may substitute for weighing.	`ziax-seat-manufacturing-2025`
`b_stocks`	all inventory rows	For each actual raw material, supplied component, regrind store, auxiliary, water-loop reservoir, in-process fluid, oil reservoir, installed refrigerant charge and adsorbent bed, retain disjoint opening/closing physical quantities, composition and per-exchange inherited burden vectors. Distinguish receipts, issues, returns, retained charge, real loss and outward transfers. Establish consumed burden by the stock_ledger rule before product allocation; raw receipt or refill is not automatically consumption. Retained media may provide service without losing mass: substantiate the assigned service burden and remaining vector with actual service/turnover evidence, not an assumed lifetime or full-charge factor; unresolved attribution remains a gap. Stocks already in product WIP or the separate packaging account cannot also enter this correction. Internal transfers preserve vectors and cancel at the consolidated gate; stock losses retain their burdens. Keep already assigned production/service trace vectors separate from unassigned stock burden entering C_j; a physical return or reused part never charges its original production again.	`ifc-plastics-manufacturing-2007`; `ilcd-attributional-allocation-2010`
`b_wip`	manufacture	For every exchange j retain opening and closing WIP physical quantity, stage, composition and inherited burden vector. Assign raw current manufacturing expenditure and opening inherited burdens to actual output/waste/remaining WIP by traceable stage and allocation. Subtract only the evidenced closing-WIP vector to carry it forward. All failed and loss-producing operations retain burdens.	`ifc-plastics-manufacturing-2007`
`b_service`	released_service	Keep actual packing, warehouse, handling, dispatch, return inspection and incremental repair in a cohort-linked service ledger. Preserve opening/closing FG and repair WIP physical quantities and inherited production/service vectors, original dispatch reversals on external return and actual incremental repair inputs/waste. Trace the removed component vector and remaining-set vector without subtracting the original production a second time or creating a credit; add only actual new component/repair-service burdens. Reusable removed parts retain their own stock/vector. Allocate historical-cohort services to their original release mass; never divide them by unrelated new production. Disclose the observed service window and unobserved future services.	`ziax-seat-manufacturing-2025`
`b_physical`	manufacture; released_service	Use disjoint raw physical gates before allocation. For manufacture, actual boundary inputs + opening raw/auxiliary/regrind/in-process fluid/water-loop/oil/installed-charge/adsorbent stocks + opening product WIP = first release + corresponding closing stocks + closing product WIP + each actual external output/loss. Count whole preparations once and reconcile their constituent subaccounts. For the FG/repair gate, opening FG + new release + actual external returned sets + actual components issued into repair + opening repair WIP = closing FG + gross physical dispatch + actual whole-set rejects + actual removed-component outputs/losses + closing repair WIP; exclude packaging and separately reconcile unissued component/reusable removed-part stores. A removed component retained for reuse is a measured transfer into that store, not waste. Keep the repair subledger: incoming set mass + actual new component mass + opening repair WIP = repaired-set mass + actual removed-component/loss mass + closing repair WIP. Do not assume new and removed parts weigh the same. Internal release/regrind/repair/reuse transfers cancel in the consolidated gate; repair never creates new Q. Check total wet/dry mass and relevant C/Ti/metal/halogen balances independently from chemical speciation and water-phase evidence. Do not fit two unknowns with one residual. Non-reactive PP moulding implies no default reaction water; free/absorbed water, vapour and any genuinely documented reaction/structural water stay distinct.	`ifc-plastics-manufacturing-2007`
`b_packaging`	released_service	For each individual sleeve, carton, tape, leaflet and pallet: opening empty + opening attached WIP/FG + opening reusable pool + purchases + external returns received = closing empty + closing attached WIP/FG + closing reusable pool + packaging leaving with gross physical shipments + outward returns + waste. Carry attached inbound packaging on returned sets explicitly; internal reuse cancels. Supplier-included inbound sacks are reconciled separately. Packaging never enters net product Q, a second purchase or an automatic co-product.	`ziax-seat-manufacturing-2025`
`b_utilities`	all inventory rows	This bounded route uses electric heat/drives; it does not presume fuel combustion, steam, a boiler or condensate. Actual external cooling supply/return needs paired water-state measurements, heat transfer and supplier burden convention. Record any actually occurring purchased compressed air, fuel, heat, filter, chemical, component, waste and identified gas species as its own atomic card/protocol before using the dataset; a true route extension needs evidence and cannot be buried in zero, other or an aggregate flow.	`ifc-plastics-manufacturing-2007`

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
manufacture	Pellet receipt through complete-set first release	required	§1 bounded PP-homopolymer set route	Complete receipt/dosing/actual conditioning/injection/cooling/ejection/trimming/regrind/assembly/QC manufacture	1 kg
released_service	Released-cohort packing warehouse and dispatch service	conditional	Actual observed post-release services of original cohort	Separate service add-on; internal transfers cancel and no new Q	1 kg

Use foreground amounts only where the actual exchange occurs; evidenced absence is distinct from an unmeasured unknown. Retain unnormalized raw totals first; each card amount refers only to the same single normalization result in §8. Service aligns to original release cohorts; future unobserved service is not presented as complete. Card descriptions and the §1/section conditions form the full consumable context.

Polypropylene (`pp_resin`)

Incoming unfilled injection-grade PP homopolymer pellets including the supplied stabilizer package. CAS9003-07-0; native record is semicrystalline PP production mix at factory with Mass only. Native grade/form/geography are unspecified; require actual homopolymer grade, pellet condition, supplier and site compatibility. Its classification under other polymer families is metadata debt; neither that classification nor its indicative melting commentary establishes the actual recipe, performance or processing temperature. Purchase this supplied resin once; its constituent assays are subaccounts.

Baths, wash-basins, lavatory pans and covers, flushing cisterns and similar sanitary ware, of plastics (`finished`)

Only the complete unfoamed uncoated non-electric PP homopolymer seat ring plus lid, conventional pivot hinge, declared bumpers and bowl-fixing components of one defined configuration at its first quality release. Native Product identity is manufactured plastic sanitary ware, production mix at plant, with Mass only; no CAS, polymer grade, geometry, route, performance standard, lifetime or geography is fixed. The broad native name is used only for this qualified subset; it is not a cistern, basin, ceramic fixture, raw resin or performance-equivalence claim. Q excludes transport packaging and includes newly released closing FG exactly once.

7. Allocation and Co-product Handling

The following rules are limited to attributional process multifunctionality. General industrial documents do not establish LCA allocation; the allocation context comes from ILCD.

rule_id	applies_to	rule	source_ids
`a_scenario`	all shared processes	These provisions apply only to an explicit attributional allocation-required scenario after goal/context assessment. Do not treat process physical/economic allocation as a free choice, consequential substitution rule or multifunctional-product QFD.	`ilcd-attributional-allocation-2010`
`a_subdivide`	all shared processes	First collect dedicated unit operations and product-exclusive material/energy/waste records. Use actual or defensible virtual subdivision for remaining separable parts. Assembly inputs unique to this configured set remain dedicated; do not allocate them to unrelated products. Document infeasibility and material distortion before leaving a common process.	`ilcd-attributional-allocation-2010`
`a_causality`	each remaining shared exchange	Identify the determining physical relation separately for each exchange: how changing the quantity of each delivered product changes that actual input/output. A validated cycle/shot load model may differ from material incorporation, cleaning area or warehouse occupied-volume-time. Test operating/load records; mass, item count or machine time is not automatically causal. Different exchanges may need different criteria. Ring and lid jointly forming one set are internal components, not saleable coproducts by default.	`ilcd-attributional-allocation-2010`
`a_residual`	genuinely unresolved common-process exchanges	Only after justifying that determining physical causality cannot resolve an exchange, allocate that genuine remainder by contemporaneous market value at the actual common-process gate and actual quality, bulk amount and packaged/unpackaged state. Remove later product-specific transport/conditioning/service costs from downstream prices. Retain evidence and sensitivity; no fixed ratio, arbitrary physical/economic selector, zero-value waste adjustment or automatic avoided-product credit.	`ilcd-attributional-allocation-2010`
`a_regrind`	manufacture; released_service	Eligible internal PP regrind retains its exact identity, pigment/contamination state and inherited vector plus grinding/drying/reprocessing increments. It is neither new virgin purchase nor burden-free output. Separately sold scrap requires demonstrated destination and explicit system-boundary/allocation treatment; do not net it from virgin feed or add a credit automatically. External returned seat repairs remain original-cohort increments.	`ilcd-attributional-allocation-2010`; `ifc-plastics-manufacturing-2007`
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.

System boundary rules · 9

Rule ID	Applies to	Rule	Source IDs
`b_complete`	manufacture	Include receipt and inbound movement, dosing, actual moisture/temperature conditioning, mould heating and all injection/cooling/ejection cycles, trimming, in-process inspection, eligible regrinding, assembly and destructive/final testing. Retain failed runs, zero-output campaigns, start/stop, idle and cleanup. A bought complete seat may not stand in for these operations.	ifc-plastics-manufacturing-2007, ziax-seat-manufacturing-2025
`b_inputs`	all inventory rows	Count each whole supplied preparation/assembly once. Assay, carrier water, embedded materials and active ingredients are subaccounts. Actual in-house formulation uses each purchased constituent, mixing energy and loss. Require compatible provider coverage including raw polymerization, components and inbound transport. No cut-off is established by a missing UUID or missing meter.	ifc-plastics-manufacturing-2007
`b_q_gate`	finished	Q is the sum of actual net kg of uniquely first-released complete configurations in the cohort period. Released closing FG is already part of Q and is not an additional manufacturing output. Shipping, reinspection, returned-set repair and internal reuse do not create Q. Unreleased ring/lid parts remain WIP. No fixed single-set kg, assumed density or source-derived test weight may substitute for weighing.	ziax-seat-manufacturing-2025
`b_stocks`	all inventory rows	For each actual raw material, supplied component, regrind store, auxiliary, water-loop reservoir, in-process fluid, oil reservoir, installed refrigerant charge and adsorbent bed, retain disjoint opening/closing physical quantities, composition and per-exchange inherited burden vectors. Distinguish receipts, issues, returns, retained charge, real loss and outward transfers. Establish consumed burden by the stock_ledger rule before product allocation; raw receipt or refill is not automatically consumption. Retained media may provide service without losing mass: substantiate the assigned service burden and remaining vector with actual service/turnover evidence, not an assumed lifetime or full-charge factor; unresolved attribution remains a gap. Stocks already in product WIP or the separate packaging account cannot also enter this correction. Internal transfers preserve vectors and cancel at the consolidated gate; stock losses retain their burdens. Keep already assigned production/service trace vectors separate from unassigned stock burden entering C_j; a physical return or reused part never charges its original production again.	ifc-plastics-manufacturing-2007, ilcd-attributional-allocation-2010
`b_wip`	manufacture	For every exchange j retain opening and closing WIP physical quantity, stage, composition and inherited burden vector. Assign raw current manufacturing expenditure and opening inherited burdens to actual output/waste/remaining WIP by traceable stage and allocation. Subtract only the evidenced closing-WIP vector to carry it forward. All failed and loss-producing operations retain burdens.	ifc-plastics-manufacturing-2007
`b_service`	released_service	Keep actual packing, warehouse, handling, dispatch, return inspection and incremental repair in a cohort-linked service ledger. Preserve opening/closing FG and repair WIP physical quantities and inherited production/service vectors, original dispatch reversals on external return and actual incremental repair inputs/waste. Trace the removed component vector and remaining-set vector without subtracting the original production a second time or creating a credit; add only actual new component/repair-service burdens. Reusable removed parts retain their own stock/vector. Allocate historical-cohort services to their original release mass; never divide them by unrelated new production. Disclose the observed service window and unobserved future services.	ziax-seat-manufacturing-2025
`b_physical`	manufacture; released_service	Use disjoint raw physical gates before allocation. For manufacture, actual boundary inputs + opening raw/auxiliary/regrind/in-process fluid/water-loop/oil/installed-charge/adsorbent stocks + opening product WIP = first release + corresponding closing stocks + closing product WIP + each actual external output/loss. Count whole preparations once and reconcile their constituent subaccounts. For the FG/repair gate, opening FG + new release + actual external returned sets + actual components issued into repair + opening repair WIP = closing FG + gross physical dispatch + actual whole-set rejects + actual removed-component outputs/losses + closing repair WIP; exclude packaging and separately reconcile unissued component/reusable removed-part stores. A removed component retained for reuse is a measured transfer into that store, not waste. Keep the repair subledger: incoming set mass + actual new component mass + opening repair WIP = repaired-set mass + actual removed-component/loss mass + closing repair WIP. Do not assume new and removed parts weigh the same. Internal release/regrind/repair/reuse transfers cancel in the consolidated gate; repair never creates new Q. Check total wet/dry mass and relevant C/Ti/metal/halogen balances independently from chemical speciation and water-phase evidence. Do not fit two unknowns with one residual. Non-reactive PP moulding implies no default reaction water; free/absorbed water, vapour and any genuinely documented reaction/structural water stay distinct.	ifc-plastics-manufacturing-2007
`b_packaging`	released_service	For each individual sleeve, carton, tape, leaflet and pallet: opening empty + opening attached WIP/FG + opening reusable pool + purchases + external returns received = closing empty + closing attached WIP/FG + closing reusable pool + packaging leaving with gross physical shipments + outward returns + waste. Carry attached inbound packaging on returned sets explicitly; internal reuse cancels. Supplier-included inbound sacks are reconciled separately. Packaging never enters net product Q, a second purchase or an automatic co-product.	ziax-seat-manufacturing-2025
`b_utilities`	all inventory rows	This bounded route uses electric heat/drives; it does not presume fuel combustion, steam, a boiler or condensate. Actual external cooling supply/return needs paired water-state measurements, heat transfer and supplier burden convention. Record any actually occurring purchased compressed air, fuel, heat, filter, chemical, component, waste and identified gas species as its own atomic card/protocol before using the dataset; a true route extension needs evidence and cannot be buried in zero, other or an aggregate flow.	ifc-plastics-manufacturing-2007

`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.

Validation rules · 6

Rule ID	Applies to	Rule	Source IDs
`v_identity`	all inventory rows	Verify each supplied physical/chemical article, actual occurrence, native type, all names/comments/CAS, fixed state/route/grade/form/geography, all properties and exact property-to-unit-group chain before quantitative provider binding. Broad native sanitary ware and PP displays remain qualified as in each card; no certification or grade equivalence follows from UUID presence.	ifc-plastics-manufacturing-2007, ziax-seat-manufacturing-2025
`v_raw`	all inventory rows	Require unnormalized raw records with original units, cumulative-meter versus true-rate distinction, actual conversions and exchange-specific allocations. Execute the single §8 normalization only once after raw conversion/allocation and WIP-vector reconciliation. Card amounts and collection aggregation refer to that same result; do not divide a pre-normalized factor again. Q=0 retains real loads and produces no per-unit value. Unknowns are gaps rather than verified zero or pass.	ifc-plastics-manufacturing-2007
`v_gates`	manufacture; released_service	Reconcile §5 manufacturing, FG and consolidated physical gates and every packaging equation, together with inherited burden vectors. Gross shipments, net commercial delivery, release Q and physical returns are different observables. Check rejection/destructive tests and all service repairs without creating extra production. No balancing residual may serve simultaneously as water loss and unknown chemical emission.	ifc-plastics-manufacturing-2007, ziax-seat-manufacturing-2025
`v_species`	all emission and wastewater rows	Retain actual molecule/species, phase, medium, test method, detection limits and control-device destination. Total VOC, COD, aldehyde group or mass residual does not establish specific chemical mass. Independently measure any density at that substance state; integrated liquid/gas volume is not multiplied by time again, while true rates are integrated. IFC Table4 prompts screening under its stated high-temperature condition and never establishes a universal release list or factor.	ifc-plastics-manufacturing-2007
`v_release`	finished	Require complete configuration BOM, traceable first quality release and measured net mass, plus actual declared geometric/functional/load/chemical checks. Informal supplier trial weights, catalogue dimensions and generic native identity do not certify the modeled configuration. A real unresolved terminal/manufacturing-method gap prevents completed-method claims; ordinary auxiliary identity or future factory measurements do not alone establish such a gap.	ziax-seat-manufacturing-2025, glasfil-pp-seat-trials
`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.
