Sodium stearate soap powder by fatty-acid neutralisation

1. Scope and Applicability

This method covers unformulated vegetable-derived C18 sodium stearate soap powder, CAS 822-16-2, made from identified free stearic acid and purchased 50% aqueous sodium hydroxide by neutralisation, actual water removal, powder finishing, quality acceptance, packaging, included storage and factory dispatch. The real marketed >=99% powder demonstrates a specific supply form; actual assay basis, moisture, fatty-acid profile and lot acceptance must be established. No mixed-fat recipe is inferred. [sigma-s3381; us-soap-neutralisation-1983; epa-soap-1974]

Exclude deliberately mixed C16/C18 fatty-acid soaps, sodium oleate/palmitate, potassium or metal soaps, glyceride saponification, purchased-soap-base finishing, superfatted/perfumed or glycerol-added formulations, bars, liquid cleansers, nonsoap surfactants, impregnated substrates and their finished articles. A changed feed, formula, route or physical state requires a separate applicability decision, not pooling under the classification label. The boundary is not a claim that the named producer uses the specified route. Historical patent examples include composite additives; their 12% moisture, recipes, airflow and energy are not defaults for this powder. [us-soap-neutralisation-1983]

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 actual net accepted external delivered powder mass for one product/route/state cohort. Exclude packaging tare, internal transfers, undelivered finished stock and already counted returns. Deduplicate physical lot/portion IDs; returned and reaccepted material creates no additional Q. Retained moisture is included; dry-active analysis is a subledger, not another reference.
inventory_carry	all inventory rows			Keep separate manufacturing, FG and combined physical gates. FG: opening + actual new release + external returns + independently measured actual material/moisture entering FG = closing + gross outward dispatch G + actual FG waste, vapour and other physical exits. Track dry C18 salt, free water and other actual species independently at opening, release, return, rework, closing and dispatch. Cancel internal production/rework handovers only once; release plus closing FG is not a double output. Net accepted delivery Q follows calc_delivery, not G or release. Every raw/WIP and non-WIP water loop, steam/condensate, cooling fluid, lubricant, refrigerant and equipment charge retains independent physical amount/state/location AND each inherited exchange vector, with original cohort/history and no overlapping stocks. Add every actual charge makeup, recovery, leak, replacement and disposal as a specific atomic exchange before data use.
single_normalisation	all inventory rows	Mass / Energy	kg; MJ	Collect raw period numerators without dividing. Attribute actual failed/zero-output runs, returns/rework, utilities, warehouse/packing/handling/dispatch and treatment burdens to their matched cohort including stock carryover. calc_normalise alone divides the resulting numerator B_i by Q once. Card amount rules and protocol aggregation are the same report operation, never sequential divisions. No positive Q means no finite per-kg dataset.
wet_supply	whole wet material supplies	Mass	kg	Purchase each whole wet solution once. NaOH assay and carrier water are component subledgers. With onsite preparation, separately acquired ingredients and actual mixing/dilution energy/loss replace the formulation purchase. Do not buy feed oil, its stearic acid and a whole soap base again for the same upstream material.
unit_conversion	all inventory rows	Mass / Energy / Volume	kg; MJ; m3	Use 1000 kg/t and 3.6 MJ/kWh. Convert liquid volumes using measured density at recorded conditions. Rate times duration is valid; an integrated volume is not multiplied by time again. Steam supply and condensate return masses remain separate physical records; heat service uses each actual measured mass and state enthalpy. Heat is not water mass, and secondary flow-property coefficients are not density.
species_water	physical material and species ledgers	Mass	kg	Check whole physical mass and C/H/O/Na separately from species reaction chemistry. For confirmed stearic-acid neutralisation, C18H36O2 + NaOH -> C18H35NaO2 + H2O forms one mole water per reacted mole and no glycerol. Glyceride + 3NaOH -> glycerol + 3soap does not itself form net water and is outside this route. Free water, evaporation, condensation and any structural water are separately evidenced; never fit reaction water and an unknown outlet to one closure residual or COD.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Receipt of specified vegetable-derived free C18 stearic acid and purchased whole 50% NaOH solution, not fats or soap base
starting_condition_role	foreground_collection_boundary
product_classification_scope	Only the single-soap powder subset of CPC35321
recursive_input_rule	Cancel internal soap, dust, condensate and rework handovers; external soap-base inputs change applicability and require upstream burden, not recursion into the final reference
upstream_dataset_requirement	Match origin and processing of whole acid, whole caustic, utilities and actual packaging; include applicable cultivation/oil extraction/refining, fat splitting, hydrogenation/fractionation and acid purification in supplied-acid backgrounds without inventing their presence or omission
disclosure	Actual site/geography, period/cohort, delivery gate, included storage temperature/time, packaging, dispatch/loading, stock burdens, outsourced stages and treatment; no supplier route inferred from catalogue

rule_id	applies_to	rule	source_ids
boundary_stages	all inventory rows	Include receiving/storage, melting, solution handling, neutralisation, actual removal of water, milling/sieving, air systems, pollution controls, cleaning, QA, packing, warehouse and dispatch handling up to the actual factory-delivery gate. Include real rework and failed runs, plus upstream and external treatment links.	epa-soap-1974; us-soap-neutralisation-1983
boundary_actual	all inventory rows	Atomic cards are a collection starting set, not a fixed plant recipe. Every actual extra package component, cleaner, utility, refrigerant loss, onsite fuel, treatment reagent, waste or elementary species requires an additional atomic card and protocol. Demonstrated absence permits not_applicable; a blank UUID or catalogue silence does not permit omission.	epa-soap-1974
boundary_sources	all inventory rows	The producer page identifies a real high-purity plant-origin powder, not this supplier route or water/packaging composition. Its ambient shipment and 2-8 C storage differ; match actual conditions and retain refrigeration burdens when present. The ester metadata label conflicts with its carboxylate formula and is not a reaction basis. Patent Example I contains glycerol and composite additives: its formulation is not transferred.	sigma-s3381; us-soap-neutralisation-1983
boundary_physical	all inventory rows	Independently close manufacturing, FG and combined total mass, C/H/O/Na and actual species/phase ledgers. Drying/ventilation has separately measured gross N2, O2, Ar, atmospheric-origin CO2 and gaseous H2O intake/outlets; no fixed air recipe or automatic fossil CO2/uptake credit. Purchased compressed-air carriers are composition child accounts, not duplicate environmental intake. Actual gas reaction/uptake, condensate, droplets and aerosols require separate measured identities/destinations. Packaging custody and external steam-water supply/return remain gross physical exchanges regardless of allocation.
boundary_pack	hdpe_body; hdpe_lid	For EACH actual separate article: opening empty + opening attachedWIP + opening attachedFG + opening reusable + new external purchase/supplier-attached receipt + external return received = closing empty + closing attachedWIP + closing attachedFG + closing reusable + article accompanying every gross physical dispatch + separate external return sent + actual article waste. New purchase and attached supplier receipt count once; contents are independent from dry tare. Internal reuse cancels within custody, never reduces gross outward article mass, raises net powder Q or creates automatic credit. Add every genuinely different material/article and its five external directions.

Inputs

Product flows

Stearic acid feed (stearic_acid)

Purchased vegetable-derived C18 stearic acid, CAS 57-11-4, as a whole supplied material. Require fatty-acid profile, acid value, water, residual glycerides and supplier route; do not substitute commercial C16/C18 mixed acids or oils. Melting and feed handling remain included.

Purchased caustic solution (caustic_solution)

Whole purchased 50% aqueous NaOH solution. Record actual assay and whole wet mass; active NaOH and carrier water are subledgers, not extra purchases. Native source-paper reagent role supplies no supplier, production route, geography or quantity. Different concentration requires another verified identity; onsite dilution includes separately acquired water and energy without purchasing the resulting mixture again.

Deionised make-up water (process_water)

Only separately supplied deionised process and cleaning make-up water, excluding water already inside purchased caustic. Native route qualifier is ion exchange or reverse osmosis; broader comment also mentions distillation, so do not silently adopt it for a distillation-only supplier. No geographic limit or density is stated. Its CPC18000 natural-water classification does not describe the treated-water identity; retain this metadata debt while matching actual deionised-water supply.

Purchased electricity (electricity)

Include melting, mixing, drying, milling/sieving, air movement, dust control, packing, cleaning and attributable warehouse/dispatch electricity. Match voltage, geography and supply period; no generic CN low-voltage UUID is assigned to an unspecified site. Capture refrigeration electricity if storage actually requires it.

Indirect purchased steam heat (steam_heat)

Conditional actual external indirect heat, calculated from independently measured steam supply mass/state/enthalpy and actual external condensate return mass/state/enthalpy; do not assume supply and return masses equal. Keep steam_water_supply and condensate_return as distinct physical exchanges with loop/equipment stocks and actual losses. Agree supplier water/energy and upstream-burden ownership: heat service and carrier-water records must not purchase the same steam production twice. An onsite boiler requires its actual separate fuel, water and emissions instead; direct-contact steam needs its actual mass/state and renewed applicability review.

HDPE package body (hdpe_body)

One actual HDPE drum body if used. Weigh tare by package design and reconcile issued, returned, damaged and stock quantities; do not infer packaging from net product mass or a catalogue pack size. Record actual new supply or supplier-attached receipt once and dry tare independently of contents. Apply boundary_pack to empty, attached WIP/FG and reusable stocks and all five external directions; the actual physical dispatch mass never falls with reuse or allocation.

HDPE package lid (hdpe_lid)

One separate actual HDPE lid if used; body mass excludes it. Other closure resin, liner, seal, label or outer carton requires its own atomic exchange and collection record. An alternative package is not evidence that actual packaging can be omitted. Record actual new supply or supplier-attached receipt once and dry tare independently of contents. Apply boundary_pack to empty, attached WIP/FG and reusable stocks and all five external directions; the actual physical dispatch mass never falls with reuse or allocation.

External indirect-heating steam water supply (steam_water_supply)

Actual externally supplied steam as physical H2O mass with measured quality, pressure, temperature, enthalpy and supplier water/energy agreement. Separate from calculated heat service; assign its upstream production once under the agreed provider convention, never duplicate it across the two records. Track actual loop charge and independently measured return/loss.

Soap (fg_return)

Actual externally returned specified C18 powder by original physical portion, measured moisture/dry salt/state, historical exchange vector and original delivery correction. Reacceptance is not new manufacture. This is a gross custody record; netting under calc_delivery cannot erase actual mass, rework inputs or outlets. The broad native Product identity permits fatty-acid alkali salts but has no CAS/form/grade/geography restriction; actual C18 powder qualification remains mandatory.

One actual complete HDPE packaging drum body. Apply the full per-article boundary_pack equation at measured dry tare, independent of contents. This separate return_received direction is actual physical custody; retain attached WIP/FG and reusable stocks, lineage, destination and inherited exchange vectors. Gross outward mass is never reduced by reuse, return netting or allocation. Other real resin/article requires its own atomic card.

Outputs

Product flows

Net delivered sodium stearate powder (product)

Terminal Product output only: actual net external accepted delivery of the specified powder, after powder finishing, quality acceptance, actual packaging, included storage and dispatch handling. Native Soap is a broad alkali-fatty-acid salt identity with no CAS, grade, form or geography; this method and lot evidence supply the narrower C18 powder qualifiers. Packaging tare is excluded; actual retained water and impurities remain in the net powder mass. The fixed 1 kg is the net-delivery reference representation of the gross dispatch/return custody ledger, not an extra physical shipment added to gross_dispatch. Preserve actual new water/cleaner/packaging/energy entering returned FG rework and each measured moisture/species/waste exit under its causing cohort; water gain/loss is not new soap manufacture. Old cohort denominators and exchange vectors remain in correction provenance; incremental services follow the declared matched net-delivery basis, never unrelated current output.

Soap (gross_dispatch)

Actual gross physical outward specified powder, including redelivery, measured net of package tare by portion and moisture/state. Keep old dispatch/return reversals and original vectors. This custody amount G is not Q; the one net product reference represents the reconciled accepted delivery, so never append gross_dispatch as a second model product output on top of that reference.

Waste flows

Soap-bearing cleaning wastewater (wash_water)

Actual external wet wastewater from equipment cleaning and off-spec handling; measure water, sodium, stearate and actual contaminants independently of COD. Link receiving treatment and its burden. Internal wash liquor reused within the boundary is an internal transfer, not another waste export.

Elementary flows

Process water vapour to air (water_vapour)

Measure the actual gross ordinary gaseous H2O crossing the external air boundary after controls, including uncondensed carrier moisture and actual process/FG evaporation. Independently measure inlet humidity, phase changes, retained moisture and stock changes. Net newly evaporated process water is an origin subaccount inside this gross outlet, never another output. Do not assume all inlet water exits as vapour: liquid condensate, droplets and aqueous aerosols need their own actual atomic destinations. Reaction-water formation is independently calculated from reacted species and is not automatically an emitted vapour quantity. No single residual may fit unknown phases/species. Adopt only ordinary gaseous H2O CAS7732-18-5 to ordinary external air unspecified, Mass reference factor1, no geographic/technology restriction or other property. Registry synonyms mentioning ice, bound or isotope water do not authorize those forms; known other compartments need another verified identity.

Uncaptured stearate dust to air (soap_dust)

Actual stack and fugitive powder losses after controls, measured by exhaust flow and species-specific particulate sampling with duration. Captured dust returned to process is not emitted. Any other measured emission requires a separate species and compartment row.

Actual single carrier species at the external atmospheric outlet of drying/ventilation. Determine mass independently from integrated gas measurement, actual P/T/composition and origin; no fixed dry-air proportions or inferred zero reaction/uptake. Purchased carrier belongs to its product child account instead of another resource input. Passing atmospheric CO2 is not new fossil generation or a credit.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_single	all inventory rows	This free-acid route produces no reaction glycerol and defines only soap powder as the reference. Do not add hypothetical glycerol output, substitution credit, soap-base credit or avoided waste-treatment benefit. Upstream fat-splitting glycerol belongs to the supplied-acid background with its disclosed allocation.	epa-soap-1974; us-soap-neutralisation-1983
allocation_actual	all inventory rows	Establish the study situation first: these provisions apply when attributional allocation is required; industrial route evidence does not authorize consequential substitution. First subdivide actual distinguishable operations or use evidenced virtual subdivision to assign exclusive materials, failures, cleanup, package and service exchanges. For each still-shared exchange independently establish the determining physical cause and measured driver, including actual state/time/geometry as relevant; mass or output count is not universal causality. Only a genuine residual without determining physical assignment uses relative market values of actual cofunctions at the same process exit/entry gate, condition and period, removing downstream transport/conditioning/packaging costs where needed. Collect quantities, prices/currency/date, allocation-sum conservation and sensitivity. Unknown cause/value evidence leaves the concrete dataset incomplete; no arbitrary fixed key. Internal return/rework/dust is not a coproduct or credit; actual external recovery follows applicable recycling provisions.	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

Named owners collect original records without division. Protocol aggregation and card formulas refer to the one downstream calc_normalise operation. Collection includes the full reporting period, zero-output/failed runs and complete WIP/finished-stock carryover; absence needs evidence, not assumed zero.

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
calc_raw	all inventory rows	Retain each external whole-supply raw exchange once; reconcile receipts/issues/returns and opening/closing unreacted material. Convert tonnes to kg; kWh to MJ by 3.6; liquid integrated volume to mass by measured-condition density. Heat is net delivered enthalpy. Rate x duration is allowed; integrated volume gets no extra time. Subledgers are not duplicate exchanges.	cp_material; cp_energy; cp_pack; cp_outlets	raw_exchange_vectors	epa-soap-1974
calc_delivery	product	Q = unique net externally delivered and accepted powder mass of the declared cohort after linked return adjustments; never count re-delivery of the same already counted physical portion twice. A return reverses the original delivery recognition for that physical portion; later re-delivery restores it once and creates no new production. Record prior-period corrections so neither the original and replacement delivery nor their history burdens are duplicated. Keep opening + releases + physical returns + actual new FG material/moisture = gross dispatch + closing + all actual FG waste/vapour/other exits, with separate new-production and delivered quantities. Unresolved return lineage or nonpositive Q blocks reporting. Independently retain gross G, external returned mass and water/dry-salt/state changes; the simplified FG equation must include actual new material/moisture inputs and real vapour/waste/other exits, not force release plus returns into unchanged wet mass. Preserve the original Q and numerator of affected historical reports for explicit corrections; re-delivery restores only the actually accepted reconditioned portion/state once, never old mass blindly and never new manufacture.	cp_output; cp_balance	Q
calc_carry	all inventory rows	For each burden vector B_i, take complete actual period raw burden plus opening WIP/finished carried burden and inbound returned-product carried burden not already included in opening stock, with linked prior-report corrections, minus closing WIP/undelivered finished carried burden and separately justified other-product shares. Assign retained failed/zero-output and irrecoverable-loss burdens to the responsible cohort; include actual rework, cleaning, treatment, storage, packaging, handling and dispatch. Physical stock balances and burden balances are separate. Stage/warehouse handovers cancel, including prior stock load rather than treating it as zero. Carry external returned-product history without recreating production. Extend the same per-exchange opening/current/closing reconciliation to non-WIP loops and equipment charges at each declared location; every genuine change in remaining stock keeps its inherited vector, not only purchase expenditure. Actual new FG/rework inputs, exits and incremental services belong to the causally matching net-delivery cohort. Do not use one old cohort burden or denominator for unrelated current output. Net delivery reference and gross custody cards are alternative accounting views of the same product movements, never additive duplicate product exports.	raw_exchange_vectors; cp_balance; cp_output; cp_energy; cp_pack; cp_outlets	B_i
calc_chemistry	all inventory rows	Independently establish reaction extent xi from identified reacted C18 acid/NaOH and residual assays: n(H2O formed) = xi; n(glycerol formed) = 0 for this route. Use documented molar masses for mass conversion. Distinguish incoming solution water, residual free water, evaporation, condensate and any evidenced structural water. Confirm C/H/O/Na and complete mass with WIP/stock. Do not infer xi from an unknown water outlet or closure residual; a glyceride route needs another method.	cp_balance; cp_material; cp_output; cp_outlets	independent_species_and_water_balance	us-soap-neutralisation-1983; epa-soap-1974
calc_normalise	all inventory rows	For every non-reference exchange, report B_i / Q exactly once after calc_raw and calc_carry; Q is from calc_delivery, not production release or dry-active mass. The product output is 1 kg. Inventory expressions and protocol aggregation describe this same report, not successive divisions. Preserve all unnormalised ledgers and conversion/attribution provenance.	B_i; Q; cp_output; cp_material; cp_energy; cp_pack; cp_outlets; cp_balance	normalised_inventory
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	Confirm actual C18 profile, vegetable origin, assay basis, powder state and route; product name/CAS alone or nonaqueous titration cannot establish the complete composition. UUID supports only its native identity limitations; background compatibility is independent.	Supplier CoA/SDS, fatty-acid analysis, site route and background documentation
dq_complete	all inventory rows	Complete raw periods, failed runs, returned/reworked portions, physical WIP/finished stocks and their full carried burden vectors must reconcile. Document sampling uncertainty and missing-data resolution before quantitative use.	Raw ledgers, transfer genealogy, calibrated meters and independent balances
dq_sources	all inventory rows	Historical EPA/patent descriptions are route evidence, not modern inventory or scientific approval. Producer page provides no lot water, package, manufacturing route or climate inventory. Match actual storage/transport conditions, suppliers, place and time.	Primary originals, full source limitations and collected activity records

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_reference	product	Require product as the sole terminal net-delivery reference with reference_flow_link product, the Soap UUID, Mass/kg and 1 kg; gross_dispatch is its gross custody ledger, never an additional net product output; verify declared C18 powder qualifiers and actual net delivery gate. Intermediate soap or internal returns cannot become another reference under the same UUID.
validate_accounts	all inventory rows	Require positive Q, matched raw/cohort records, complete WIP/finished burden carryover, return deduplication, no double procurement and exactly one normalisation. Verify production release and delivery separately; no closing-stock double output and no omitted warehouse/packing/dispatch/rework load. Independently close the manufacturing, FG and combined physical/species gates, non-WIP physical and inherited exchange stocks, all package directions and steam carrier supply/return. Gross product custody must reconcile to the single net reference rather than add duplicate product exports. Verify separate phase outlets and original return corrections with each actual new rework input and loss.
validate_chemistry	all inventory rows	Require independent complete mass/element and species/water evidence. Reject generic reaction-water assumptions, glycerol reference/credits, COD or residual fitted unknown outlets and integrated-volume time multiplication. Check active, water and whole-supply subledger agreement.	us-soap-neutralisation-1983; epa-soap-1974
validate_boundaries	all inventory rows	Check actual atomic utility/package/treatment/emission completeness, native property/unit and geography limits, provider and source applicability. Empty auxiliary UUIDs remain disclosed identity work; they do not erase actual flows. Source limitations and stock burdens remain in both language renderings and projection.
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.
