Live reptiles

1. Scope and Applicability

This PCR covers living, identified reptiles, including eligible snakes, lizards, crocodilians and turtles, delivered alive at the actual captive-breeder or authorized live-capture source gate. Species-level legal provenance and a documented route are mandatory; CPC classification is not permission to trade protected animals. Captive husbandry and lawful collection have different burdens and must not be averaged as though every reptile were farmed. Amphibians, dead reptiles, skins, meat, detached eggs, slaughter and post-gate buyer transport are excluded from the live reference. Species-specific temperature, lighting, feeding, aquatic/terrestrial holding and welfare practices are actual route facts, not universal defaults.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
m_live_mass	Reference and live transfers	Mass	kg	Weigh live animals at actual handover; preserve count and size class. Do not use a universal kg/animal conversion across taxa.
m_input_mass	Feed, stock and waste	Mass	kg	Use measured wet/as-purchased state and disclose any dry-matter conversion separately.
m_time	Cohorts, capture campaigns and shared facilities	Time	day or declared period	Assign inputs, mortality, output and assets to actual periods; no default lifetime is assumed.
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	Captive route: opening breeding/juvenile stock with count, mass and carried burden, or purchased stock with supplier burden. Capture route: licensed source population/access and actual campaign; no fictitious breeder stock.
starting_condition_role	Breeding/juvenile stock is biological Product input or disclosed opening asset; wild population is capture context, not a zero-burden purchased animal.
product_classification_scope	CPC 3.0 02195 living reptiles only, after species and legal-status check.
recursive_input_rule	Link purchased same-category live reptiles once to upstream source dataset; internal rearing-to-handover transfer is not a second final sale.
upstream_dataset_requirement	Supplier species, source, gate, geography and burden for purchased animals, feed and services; permits for regulated wild or captive source.
disclosure	Taxon, source code/permit, provenance, count/mass, condition, cohort/campaign, mortality, real co-products, shared assets, route and handover gate.

Boundary Rules

rule_id	Applies to	Rule	source_ids
b_legal	Every lot	Verify species and legal source before modelling marketable live output. CITES or domestic source codes require checking; they are not blanket authorization.	un-cpc-2025; ; cites-guide-2022
b_routes	Captive or wild source	Captive production includes real breeding/rearing, stock, feed, water and environmental control; collection includes authorized live capture and actual holding but no invented captive lifetime. Stop at actual source handover.
b_shared	Shared rooms, thermal plant, pools, equipment	Assign measured service to consuming cohorts, capture/holding nodes and periods once. Separate buyer transport, slaughter and destination use.

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
captive	Breed and rear living reptiles	conditional	evidenced captive-bred/reared source	managed biological production	per kg accepted live output
capture	Lawful live collection and short holding	conditional	valid wild-collection authority; excludes captive route for same lot	independent live capture	per kg accepted live output
handover	Verify and hand over living reptiles	required	actual source gate for either route	final live acceptance	per kg accepted live output

The captive node manages named stock through real feeding, water, species-specific environmental control and health checks. Capture independently removes authorized living animals from a documented source and records actual holding, losses and handover; it does not borrow captive-production inputs. Handover is a distinct condition/count/mass and legal-documentation gate. Eggs, shed material or another product count only when independently sold at their own gate; routine residue and dead animals are not live products. Shared rooms, heated water and equipment are allocated by observed service to nodes and periods.

Electricity at the equipment supply point (captive_energy_electricity)

Collection scope and applicability for captive_energy. The following concrete identities have separate cards and apply only when use or generation is evidenced inside the original process scope. They are not mandatory inputs or a default recipe. Document non-use; missing records are not zero. Add a separate concrete card for any other actual material instead of substituting one of these names or UUIDs. Preserve attribution and boundaries and avoid double counting components included in outsourced services.

Record actual carrier for heating, lighting, filtration or humidity control where required by selected species and site. Denominator and scope requirements：per kg accepted live output

Confirm identity, grade, state and unit from equipment, supplier and contemporaneous measurements; the product UUID does not establish actual use or upstream-provider compatibility. Retain the electricity supply point, fuel grade, density and heating-value basis. Distinguish purchased heat from on-site fuel conversion without counting its input fuel again.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
a_output	Captive node	List all intended independent live and non-live outputs and their actual gates. First partition physically separable activities; if joint burdens remain, use evidenced mass or another documented causal driver and disclose sensitivity. Unsold eggs/shed and dead animals are residue/waste.	mass-balance-identity
a_period	Captive cohort or capture campaign	Link stock, facilities, feed, losses and live animals to actual periods. Allocate opening stock and shared assets once across realized outputs and service periods; no default reptile lifetime or double counting at internal transfers.	mass-balance-identity
a_shared	Heated rooms, pools, cages and handling services	Record every consuming node/cohort and period; allocate by measured service time, metered energy/water or justified capacity driver, not again at final handover.	mass-balance-identity

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.

requirement_id	collection_protocol_id	Preserved collection scope
captive_feed_specific_input	cp_resources	Operation captive: Record actual feed identity, including procured prey only where genuinely used; no universal reptile diet is assumed. Denominator and scope requirements：per kg accepted live output Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using reconciled feed-supply records that retain in-boundary losses and their production burden.
capture_supplies_specific_input	cp_resources	Operation capture: Record actual nets, traps, safe containers or purchased consumables; reusable equipment is attributed by use period. Denominator and scope requirements：per kg accepted live output Original quantity method: issue records and shared-equipment attribution
handover_containment_specific_input	cp_resources	Operation handover: Include disposable enclosure material handed with lot or consumed before gate; reusable cages are shared assets. Denominator and scope requirements：per kg accepted live output Original quantity method: measured material issued and attributed reuse if applicable

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
c_reference	accepted live output	Sum measured mass of accepted living animals of one species; normalize allocated inventory to 1 kg. Reconcile count, source transfer and rejected/dead disposition.	cp_live, cp_outputs	kg accepted live species	mass-balance-identity
c_water	captive wastewater	Supplied water minus measured retained, evaporated and separately discharged quantities; direct measurement takes precedence.	cp_resources	kg wastewater	mass-balance-identity
c_period	stock and shared service	Assign consumption to cohort/campaign and period, divide joint service by metered use or documented time and sum shares once.	cp_stock, cp_resources, cp_outputs	allocated input/kg accepted output	mass-balance-identity
calc_feed_supply_and_intake	captive_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

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
q_identity	every lot	Verify scientific taxon, legal source and jurisdiction; reject unknown/prohibited provenance.	source/permit and legal check
q_mass	reference and loss	Calibrated live mass, count, size class and condition by gate; no cross-species average kg/head.	weighing and acceptance logs
q_period	cohorts, campaigns, shared assets	Complete inputs, outputs, mortality and periods with documented attribution, opening and closing stock.	ledgers and reconciliation worksheet
q_flow	UUID-backed exchanges	Confirm exact flow, property, unit group, type and gate before binding; unresolved IDs stay unbound.	platform detail/support-row evidence

Substance-specific Release Requirement

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
captive_emission_specific_emission	captive	For the actual captive activity, preserve the original cp_emission collection role and activity/state/period basis. substance-specific measurement or documented calculation. This is a mandatory identification and calculation requirement, not one aggregate elementary exchange. Enumerate each actual emitted substance and receiving compartment using a compatible measured/pathway method and activity-factor units, then create a separate concrete card or reuse the existing matching card once, with verified UUID or explicit unresolved identity. A generic pollutant/volatile/residue label, total mass loss or summed screening interval cannot establish a compound or individual-emission amount. Keep elemental versus molecular/reporting bases explicit, attribute the raw quantities and normalize once to accepted reference output. No supported release only with evidenced inapplicability; missing identity, method or activity blocks completeness. Exclude releases already covered by an inclusive service or upstream dataset.	cp_emission	separate supported substance/compartment exchanges

9. Validation Rules

rule_id	Applies to	Rule	source_ids
v_legal	live output	Fail if species, authorized origin, condition or actual source gate is absent; classification does not prove legality.	un-cpc-2025; ; cites-guide-2022
v_routes	source process	Exactly one evidenced source route supplies each lot. Captive needs stock/cohort records; capture needs permits/campaign and cannot inherit imagined breeding inputs.
v_balance	mass and outputs	Reconcile opening/purchased or captured mass, stock changes, accepted live animals, mortality and real co-products; internal transfers and same-gate live returns only once. A later production activity requires its own responsibility and records.	mass-balance-identity
v_shared	multi-period/shared assets	Each input, asset, output and loss has node/period attribution; shares sum to observed service without double charge at two gates.	mass-balance-identity
v_identity	all cards	conditional flow cards need concrete selection; final exchanges need verified species/state/direction/property/unit and gate before publication.	un-cpc-2025
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
