Fresh non-hatching shell eggs of birds other than hens

1. Scope and Applicability

Covers fresh shell-on eggs of birds other than hens handed over for actual non-hatching use at the producer farm gate, including food and documented other unincubated uses; not human table eggs alone. Excludes hen and hatching eggs, broken/liquid/preserved/processed eggs and hatched birds. Managed laying, independent collection and farm-gate transfer are required; on-farm sorting and protective packing apply only when performed. Preserve species and lot-specific mass, count, grade, use, safety, storage time/conditions and actual gate. One kilogram does not imply cross-species nutritional or functional equivalence.

The verified CPC 02322 Product/Mass UUID matches this explicitly farm-gate, shell-on reference and the terminal output. It does not authorize a hen, hatching, processing, count-only, or different-gate exchange.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
mass	reference eggs	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Weigh shell-on mass excluding package and reconcile nodes and stocks by species/lot.
count	conversion of recorded egg counts to measured lot mass	Count plus measured Mass	eggs; kg	Retain count as a separate observed quantity. Use lot measurement or representative sample mean only to derive this lot's mass; no cross-species mean or claim that count itself has Mass property.
feed	feed	Mass	kg as-fed; kg dry matter	Retain measured conversion and source before combining as-fed/dry-matter feed.
inventory_reference_normalization	all inventory rows	Actual flow property	exchange unit per reference flow	The inventory and collection aggregation fields below express final amounts per declared reference flow. Keep all raw collection records, original denominator qualifiers, route/period strata, unit conversions and allocation requirements. For each flow, first obtain its attributable amount in its own numerator unit using the existing rules; then divide by the measured accepted reference-output quantity of the same scope and multiply by the declared reference quantity. Do not mix species, states, gates or incompatible routes; count transfers and shared burdens once. A missing, zero or untraceable accepted-output denominator is a blocking data-quality issue. Keep provisional QA ranges on their explicitly stated bases; they are not conversion factors or production defaults. Compute normalized amount = attributable amount * declared reference quantity / measured accepted reference-output quantity. Apply normalization once only; never divide an already normalized value again.
stage_throughput_linkage	stage records and final package contributions	Actual flow property and its stated raw basis	retain native numerator and stage denominator units	Keep the original lot, event, cohort, period and stage denominators with their units. Reconstruct the attributable numerator A with measured stage quantity Q_stage and documented attribution before final normalization. If a quoted amount a_B corresponds to an explicit stage basis B_stage (for example, 1000 kg), use A = a_B * Q_stage / B_stage. If r_stage is already an intensity in exchange-unit per stage-unit, instead use A = r_stage * Q_stage, with no second division by B_stage. A raw attributable total is used directly. Final contribution = A * declared reference quantity / measured accepted final output. Convert compatible units explicitly and apply each attribution/allocation share exactly once; never treat a quoted amount or intensity as a raw total. Link stage transfers, losses, rejects, stocks, shared services and allocation to the same actual route, period and final-output stratum. For a 1000 kg basis retain 1000 kg explicitly. Do not assume unit yield, equal fresh/dried mass, equal head mass, equal dose quality or interchangeable gates. Missing links, unsupported unit conversion, zero denominators and untraceable allocation block dataset production. Stage-native datasets retain their own stage reference; package contributions are a separate projection.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Admitted birds or on-site rearing history, purchased feed, supplied water, energy, health supplies and conditional packaging.
starting_condition_role	Managed laying passes through independent collection, conditional sorting/packing and farm-gate transfer.
product_classification_scope	CPC 3.0 02322; hen, hatching and processing eggs, spent birds and manure have separate identities.
recursive_input_rule	Purchased same-category eggs retain supplier dataset and distinct transfer; do not recreate laying or count as this farm's output.
upstream_dataset_requirement	Match birds, feed, water, energy, supplies and packaging upstream datasets by species, state, provider, geography and technology.
disclosure	Species, route, flock/phases, node gates, breakage/diversion/waste, storage conditions, co-outputs, shared assets and attribution.

Manure biogenic methane to air (review_laying_manure_ch4)

Calculate actual atmospheric release by manure system, climate, residence time and volatile-solids activity. Reconcile captured, destroyed or oxidised methane; produced methane is not automatically emitted methane. Applies only to the operated laying node; preserve its existing route and period conditions. A dataset must resolve actual activity, method applicability and an evidence-based range or physical bound for this pathway before treating the inventory as complete. Missing evidence is not zero or not_applicable. A verified substance/origin/compartment UUID is still required for a final bound exchange.

• Selected flow: Methane, biogenic, to air (UUID unresolved)
• Flow property / unit: Mass / kg CH4
• Amount rule: Calculate the pathway total for this node and period, apply the existing allocation and stage_throughput_linkage, then inventory_reference_normalization exactly once to the measured final accepted reference output.

Direct manure nitrous oxide to air (review_laying_direct_n2o)

Use the actual manure-management nitrogen pathway. Keep storage/treatment distinct from field application and grazing deposition, which require a managed-soil method and an explicitly assigned inventory responsibility. Applies only to the operated laying node; preserve its existing route and period conditions. A dataset must resolve actual activity, method applicability and an evidence-based range or physical bound for this pathway before treating the inventory as complete. Missing evidence is not zero or not_applicable. A verified substance/origin/compartment UUID is still required for a final bound exchange.

Indirect manure nitrogen-derived nitrous oxide to air (review_laying_indirect_n2o)

Calculate attributable indirect N2O from documented manure N volatilisation/deposition and leaching/runoff pathways where applicable. Keep separate from direct N2O and reconcile any nitrogen-fate calculation already included downstream or in the chosen background/impact model. Applies only to the operated laying node; preserve its existing route and period conditions. A dataset must resolve actual activity, method applicability and an evidence-based range or physical bound for this pathway before treating the inventory as complete. Missing evidence is not zero or not_applicable. A verified substance/origin/compartment UUID is still required for a final bound exchange.

Manure ammonia to air (review_laying_nh3)

Use actual species, housing/storage conditions and a justified nitrogen-flow method. Track total N and ammoniacal N by stage; a generic volatilised-N estimate is not automatically NH3 because it may include other nitrogen species. Applies only to the operated laying node; preserve its existing route and period conditions. A dataset must resolve actual activity, method applicability and an evidence-based range or physical bound for this pathway before treating the inventory as complete. Missing evidence is not zero or not_applicable. A verified substance/origin/compartment UUID is still required for a final bound exchange.

Concrete cards do not inherit numerical ranges from the former aggregate card. Determine quantities from original records, stock/meter reconciliation and the declared reference flow; no default quantity or numeric screen is supplied without evidence matching the identity, unit, period and boundary. Missing range evidence is a quality disclosure, not zero use or proof of completeness.

8. Foreground Data Collection, Calculation, and Quality Rules

Specific input identification before dataset completion

Identify the actual input for this operation from supplier specifications, equipment and primary records. This is a mandatory collection requirement, not an exchange. Before dataset completeness, represent each used material, formulated product, carrier or independently purchased service by one physically specific card with its native quantity/property; confirm a compatible UUID, or retain an explicit unresolved identity and do not claim a fully linked dataset. Do not substitute a conditional example for an unknown actual input, invent a recipe, omit required use or infer zero from missing records. Attribute shared use, reusable assets and inclusive services once; preserve the original stage/period and measured throughput link to final reference output. The former aggregate range is not a component limit or consumption default.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
balance	egg nodes	Input = accepted + diverted + rejected + stock change within measurement uncertainty.	lot mass and stock	reconciled kg	fao-codex-eggs
normalization	inventory	Divide actual flock/period totals by measured transferred fresh shell-egg kg in same scope.	period totals and transfer mass	per-kg inventory	fao-leap-poultry
asset	shared assets	Allocated totals from measured service drivers must equal original burden.	asset total and node use	once-attributed burden	fao-leap-poultry
calc_pathway_emissions	laying	Use species- and management-compatible methods and retain disaggregated pathway totals. Convert N2O-N to N2O by 44/28 and NH3-N to NH3 by 17/14 exactly once; already molecular masses are not reconverted. Check methane against the documented available-carbon/methane-potential balance and nitrogen losses against each stage's available N. Indirect formation from previously volatilised N is a downstream transformation, not a second source-stage N loss. Attribute and normalize once; do not duplicate linked treatment or fate-model emissions. Use matched raw-period quantities before allocation for physical screens: CH4 mass × 12/16 must not exceed the carbon available to the represented pathway; source-stage NH3 mass × 14/17 plus direct N2O mass × 28/44 and other source N losses must not exceed that stage's available N, after accounting for stocks and transfers. Bound each indirect N2O-N calculation by its documented volatilised or leached N precursor, not by subtracting that downstream transformation again from the source ledger. These are conservation checks, not emission factors or an empirical per-product range.	cp_pathway_emissions	kg named compound per final reference flow	review-ipcc-livestock-2019; review-eea-manure-2023; review-ipcc-soils-2019
calc_feed_supply_and_intake	feed	Feed supply used by the represented operation = opening feed stock + receipts + on-site feed entering the operation - closing feed stock - documented unused returns or transfers out. Retain in-boundary spoilage, refusals and discarded leftovers in that supply. Actual intake = that supply - measured uneaten/discarded losses, after matching moisture/DM and period; use intake only for nutrition/metabolism. Opening stock retains its prior burden and is not another purchase. Trace any unused return or transfer and its burden destination; no automatic substitution credit. Attribute production once, through either the purchased-feed dataset or the represented on-site crop/collection node, never both for the same feed. Include actual waste treatment and manure contributions once, not as a second feed-production burden.	cp_feed_supply_and_intake	separate feed supply, intake and loss quantities, in matched as-fed/DM units	fao-feed-loss-accounting-2018
calc_manure_n2o_coverage	review_laying_direct_n2o; review_laying_indirect_n2o	For each actual manure stage, calculate direct N2O, volatilisation/deposition-derived indirect N2O, and applicable leaching/runoff-derived indirect N2O separately with documented species/system activity and factor basis. Convert N2O-N to molecular N2O by 44/28 once; do not reconvert molecular masses. Retain component worksheets. Where an existing N2O card covers both direct and indirect emissions, report their non-overlapping sum; where separate direct/indirect cards exist, assign each component once to its matching card and never also report the sum. Pasture deposition and land application use the managed-soil method, not a manure-storage factor. Assign foreground versus linked treatment/pasture coverage explicitly; a manure export does not erase earlier emissions, and already covered downstream emissions are not repeated. Account for stock, transfers and previous N losses in the nitrogen cascade; indirect N2O is a downstream transformation of its precursor, not a second source-stage N loss. Normalize attributed molecular masses once to the accepted reference output. Document inapplicability; absent pathway data are not zero.	cp_manure_n2o_coverage	kg molecular N2O by pathway and assigned existing card	review-ipcc-livestock-2019; review-ipcc-soils-2019
chemical_species_mass_accounting	elementary_nutrient_emissions	Final elementary exchanges use the mass of the identified substance and one actual receiving compartment. Keep nutrient/activity ledgers separate: species-specific N2O-N × 44/28 gives N2O, NH3-N × 17/14 gives NH3, nitrate-N × 62/14 gives nitrate, and phosphate-P × 95/31 gives phosphate. If the selected flow is elemental phosphorus instead, report kg P and convert phosphate mass by 31/95 only when that species basis is evidenced. Apply a conversion exactly once only when the method output is on the elemental basis; measured compound mass is not reconverted. Total nutrient losses cannot be assigned to a single species without a supported split, and residual/retained soil nutrient is not an emission. Keep direct/indirect pathway ledgers and avoid repeating a pathway already included in the chosen method or upstream inventory. Factor uncertainty ranges screen factors on their stated basis, not final compound amounts or admissible site emissions. Normalize the attributable compound mass once using the accepted reference quantity and the matched measured output. Unknown activity, identity or compartment remains an evidence gap and blocks a completeness claim.	cp_pathway_emissions; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records

Data Quality Requirements

9. Validation Rules

rule_id	Applies to	Rule	source_ids
identity_gate	reference eggs	Require non-hen, fresh shell-on, measured 1 kg, actual non-hatching use and true producer gate; non-food unincubated use remains eligible.	fao-codex-eggs
route_gate	nodes	Laying and independent collection required, sorting/packing evidence-based; species and housing differences change inventory or QA.	fao-codex-eggs; fao-leap-poultry
grade_gate	grades	Sorting has at least two real destinations; hatching/processing diversions need suitability and lawful acceptance; broken eggs cannot be reference.	fao-codex-eggs
attribution_gate	co-outputs/periods/assets	Verify each handover, service period and allocated total without node/period duplication.	fao-leap-poultry
uuid_gate	concrete downstream exchanges	Verify each UUID, property and unit before downstream TIDAS process; do not force blanks.	fao-leap-poultry
v_pathway_emission_coverage	laying	Require a pathway coverage ledger for enteric CH4 where biologically applicable, manure CH4, direct/indirect N2O, NH3 and relevant field emissions. Every pathway needs a measured/calculated value, a named linked process with matching coverage, or supported inapplicability; absent data cannot become zero. Keep wild life before capture outside managed husbandry, assess actual managed holding separately, and retain species-specific evidence.	review-ipcc-livestock-2019; review-ipcc-soils-2019; review-eea-manure-2023
v_foreground_emission_responsibility	Actual operated nodes and linked services	Record responsibility for on-site fuel combustion and refrigerant leakage when applicable: either quantified foreground emissions or a named linked process explicitly covering them, never merely a fuel-supply or electricity-production input. Assess special-taxon biological and residue emissions using species/route evidence, without a generic livestock factor. Identify any unresolved pathway and withhold a completeness claim; document supported absence and prevent duplicate upstream/downstream accounting.
v_feed_supply_intake_separation	All feed inputs	Reject an upstream feed inventory reduced by in-boundary refusal, spoilage or discarded leftovers without retaining their production burden. Reconcile supply, intake, stock, transfers and loss destinations under calc_feed_supply_and_intake. Do not reuse intake as supplied feed, assume zero-burden on-site feed or grant automatic avoided-product credits.	fao-feed-loss-accounting-2018
v_manure_n2o_coverage	Applicable manure and managed-soil N pathways	Require explicit direct and indirect pathway coverage, stage N balances and molecular-mass conversion. Map each component to an existing N2O card or an explicitly covering linked process once under calc_manure_n2o_coverage. Missing indirect-pathway evidence prevents a completeness claim; no default zero or duplicate aggregate-plus-components.	review-ipcc-livestock-2019; review-ipcc-soils-2019
