Reelable silk-worm cocoons

1. Scope and Applicability

This PCR covers measured silk-worm cocoon lots demonstrated suitable for reeling at actual cocoon-producer handover. Fresh unprocessed and producer-stifled/dried reelable lots are distinct product states, never interchangeable kilograms without measured moisture normalization. Declare species/strain, grade, defect fraction, moisture, route and gate. Pierced or otherwise unreelable cocoons, live larvae, spun/raw silk, and post-handover reeling are excluded. Stifling performed only by the buyer after transfer is outside this foreground boundary.

2. Product Category Identity

Field	Value
canonical_pcr_id	pcr.agriculture-forestry-and-fishery-products.live-animals-and-animal-products-excluding-meat.silk-worm-cocoons-suitable-for-reeling
classification_refs	CPC 3.0 02944 — silk-worm cocoons suitable for reeling
covered_products	Demonstrably reelable silk-worm cocoons handed over fresh or, when conditioned by the producer, as a separately measured stifled/dried lot.
excluded_products	Pierced/unreelable cocoons, live silkworms, silk fibre or yarn, raw silk, downstream cooking and reeling.
representative_product	Graded reelable cocoon lot with state-specific as-received mass and measured moisture.
production_route	Managed host-leaf feeding and cocoon spinning; independent collection; grade selection; optional producer-side stifling/drying; protected presentation.
market_state	Fresh unprocessed or producer-stifled/dried, separately identified; reelability and actual handover gate evidenced.

The managed-biological parent is silkworm rearing through spinning. Host-leaf source, species, indoor climate and mounting regime are route deltas only when foreground evidence shows changed inventory, calculation or acceptance requirements. Fresh and producer-dried branches can coexist for different measured lots; the same cocoon cannot be counted at both handovers.

3. Reference Flow

Field	Value
What	Reelable silk-worm cocoons at actual producer handover, with fresh and producer-dried results stratified.
How much	1 kg measured as-received cocoons in the declared state, excluding container and separated rejects.
How well	Reelability evidence, species/strain, grade/defects, shell/pupa state and moisture at handover.
How long or cycle	Documented host-leaf supply, silkworm cohort, collection, grading, optional drying and handover periods; shared assets allocated across actual service periods.
reference_flow_link	reference_product_handover

Field	Value
Reference amount	1
Reference product flow	Reelable silk-worm cocoons, state and gate qualified
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Mass units 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	species/strain; host-leaf source; cohort; fresh or producer-stifled/dried state; measured moisture; reelability/grade test and rejects; actual producer gate; package mass

Instantiate one foreground reference from the actual handed-over lot, with all required qualifiers. The category may cover alternative states and producer gates, but each package has one declared species/state/gate/grade stratum and one measured accepted reference-output denominator. Do not pool incompatible states or claim equal service from equal mass. Route-specific source rows and reference_handover describe the same physical boundary event; their linked internal transfer is not another sale or another physical operation.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
cocoon_mass	accepted and rejected lots	Mass	kg	Weigh each lot at its own handover after tare removal; reconcile accepted, downgraded, waste and sampled quantities without counting one lot twice.
moisture_state	fresh and dried lots	mass fraction	kg/kg	Measure moisture on representative state-specific samples; never substitute assumed fresh-to-dry yield. To compare states calculate dry-matter mass from measured moisture and report both original as-received masses.
grade_fraction	collected and accepted lots	mass fraction	kg/kg	Record tested reelability/defect classification and accepted, downgraded and rejected masses on the same measured basis; no universal quality threshold is imposed.
period_link	cohort and shared assets	time	reporting period	Link host leaves, larvae, tray or dryer services, yield and disposal to producing cohort and period; allocate shared burdens once.
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. These are final foreground-package contributions, not replacements for stage quantitative references or stage-native unit-process datasets. Retain stage records separately. Compute normalized amount = attributable raw amount * declared reference quantity / measured accepted final reference-output quantity. Apply normalization exactly once.
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	Purchased silkworm seed/larvae and host leaves or identified on-site host crop and breeding source; identify opening cohorts and upstream burdens.
starting_condition_role	Purchased inputs cross the foreground boundary with upstream datasets; opening biological stock and reusable assets are separately disclosed.
product_classification_scope	Reelable cocoon goods only; rejected spinning-grade cocoons and raw silk are separate products.
recursive_input_rule	If purchased cocoons of this category are added, retain upstream burdens and purchased mass once; never claim them as newly reared output.
upstream_dataset_requirement	Require supplier-specific or justified secondary datasets for seed/larvae, host leaves, fuel, water, packaging and assets where applicable.
disclosure	Report cohort, route, state, moisture, grade, each output destination, gate, period, shared assets and treatment of purchased cocoon input.

Boundary Rules

rule_id	Applies to	Rule	source_ids
b_rearing	all cohorts	Include managed feeding, climate control, mounting and spinning through intact spun-cocoon handoff. Host-crop production is upstream unless explicitly inside this foreground system; avoid double-counting on-site leaves.	fao-cocoon-quality;fao-cocoon-characteristics
b_nodes	collection and grading	Collect after spinning as an independent removal node, then classify incoming cocoons into accepted reelable, independently downgraded and rejected/waste destinations; not every harvested cocoon is reelable.	fao-cocoon-quality
b_drying	optional producer conditioning	Include stifling/drying only when producer performs it before declared sale gate; meter heat, electricity, moisture loss and rejects. Buyer-side conditioning, cooking and reeling are downstream.	fao-cocoon-drying
b_gate	all outputs	Include protected packing and pre-handover handling at actual producer gate but exclude downstream distribution after ownership transfer. Fresh and dried branches require different final-output identities.	fao-cocoon-quality;fao-cocoon-drying
reference_handover_linkage	actual reference-product boundary	Record reference_handover as the same physical producer handover already represented by its source rows. It must not extend the gate or insert new processing, capture, storage, transport, service or capital burdens. For a unit-process projection, keep the actually operated stage references; the handover record may be a boundary interface in the resulting foreground package, not an invented standalone operation. Select one actual qualified route/output stratum; trace matching source and input as internal transfers and expose the accepted reference product once. If the source already ended at this gate, partition its existing handover responsibility without counting it again.

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
rear	Managed silkworm rearing and spinning	required	Cohort produces cocoons	Managed biological parent; larvae, host leaves, climate and mounting to spun cocoon	kg spun cocoons per cohort
collect	Independent cocoon collection	required	Cocoon removal after spinning	Transfer intact collected cocoons to grading; separate incidental debris and loss	kg collected cocoons
grade	Reelability grading and destination sorting	required	Every sale lot	Incoming collected cocoons split into accepted, separately downgraded and waste states	kg graded input
dry	Producer-side stifling and drying	conditional	Performed before sale of a separately identified reelable dried lot	Fresh accepted cocoons to stabilized dried cocoons; water removal and rejects	kg incoming fresh accepted cocoons
present	Protected presentation and producer handover	required	Accepted sale lot	Package and hand over fresh or dried reelable lot at one declared gate	kg as-received accepted cocoon lot
reference_handover	Actual producer reference-product handover	required	One actual declared route, state and producer gate per foreground package	Record the existing physical boundary handover once; linkage/accounting responsibility, not additional treatment or distribution	1 kg accepted product at the declared handover

Rearing and collection are separate because spinning ends before physical removal from mountages. Grading records accepted, independently marketed downgraded and waste destinations; a pierced cocoon is not reelable even if sold for spinning. The dry node receives a usable fresh grade and hands a distinct stabilized grade to presentation; dehydration is mass loss, not a co-product. Fresh and dried outputs coexist only for different measured lots. Host-leaf plots, rooms, trays, mountages, sorters and dryers shared across cohorts or nodes require documented service-period attribution.

Dead larvae of the declared silkworm species sent to treatment (rear_dead_larvae_waste)

Conditional on this exact waste stream actually being generated and documented inside the existing process boundary. Record actual species/material, physical form, grade, moisture/composition where relevant, lot, recipient, quantity and gate. A named example does not establish actual production or a default recipe.

Process: Actual producer reference-product handover (reference_handover)

Instantiate one foreground reference from the actual handed-over lot, with all required qualifiers. The category may cover alternative states and producer gates, but each package has one declared species/state/gate/grade stratum and one measured accepted reference-output denominator. Do not pool incompatible states or claim equal service from equal mass. Route-specific source rows and reference_handover describe the same physical boundary event; their linked internal transfer is not another sale or another physical operation.

Inputs

Reelable silk-worm cocoons, state and gate qualified for actual producer-handover linkage (reference_handover_input)

This input matches the accepted goods represented by fresh_farm_output, dried_gate_output under their unchanged route conditions. It is an internal source-to-handover linkage, not a newly purchased same-category good and not extra production. The matching source and input cancel at the package boundary.

The actual route/state/gate is selected from foreground handover evidence; retain every required qualifier. Use the actual terminal source for the same accepted physical lot, not every successive stage transfer. Fixed source identities apply only to their exact species/state/gate; use an unbound compatible source role for other covered routes and resolve the actual foreground exchange before final dataset creation.

a_output	separately marketed outputs	First subdivide cohort, grade and conditioning records by physical lot. If reelable and separately marketed spinning-grade cocoons are joint outputs of an indivisible operation, document and justify physical causal allocation where supported; otherwise disclose economic allocation, price period and uncertainty. Unsold rejects and moisture loss are not co-products.	fao-cocoon-quality;fao-cocoon-drying
a_period	cohorts and host-crop phases	Attribute leaf inputs, rearing operations and cocoon outputs to actual cohort and reporting period; carry opening/closing stock and unfinished cohorts across calendar cut-offs.	fao-cocoon-quality
a_shared	shared infrastructure	Record host plots, rearing rooms, trays, mountages, graders and dryers with actual consuming nodes, cohorts and service periods; allocate manufacture, repair and utilities by observed use or justified disclosed proxy only once.	fao-cocoon-quality;fao-cocoon-drying

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
host_leaves_specific_input	cp_cohort_inputs	Operation rear: Record purchased or attributed on-site leaves supplied, retaining consumed leaves and leftovers separately; do not assign zero burden to on-site leaves. Denominator and scope requirements：per kg spun cocoons from identified cohort Raw quantity and calculation requirements: Use separate feed-supply, intake and loss ledgers under calc_feed_supply_and_intake. The quantity carrying feed-production burden includes in-boundary refusals, spoilage and uneaten feed; it is not reduced to animal intake. Retain source, species/cohort, phase and original mass/moisture basis. Calculate the final contribution with inventory_reference_normalization and stage_throughput_linkage exactly once. Original collection denominator kind: process_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.
protective_pack_specific_input	cp_handover	Operation present: Record actual baskets, bags or crates by material and reuse; expand concrete materials in foreground dataset. Denominator and scope requirements：per kg as-received reelable cocoons handed over Raw quantity and calculation requirements: New material issued less returned reusable stock, allocated over verified reuse cycles. Original collection denominator kind: process_output. Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using the matched raw records.

A real mixed stream remains one measured composition-defined identity; do not invent segregation or duplicate mixture/component exports. Retained/deferred stock, in-situ residues and soil returned directly to the environment keep their actual balance/stock/return roles, not assumed technosphere waste exports; establish method and boundary responsibility before any elementary exchange.

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
seed_larvae_identity_and_fate	rear	For the original seed_larvae collection role at this operation, identify the actual physical form, species/material, composition, state and supply/treatment boundary before creating exchanges. Each seed lot, transplant, crown, cutting, larval stage, formulation, coating, preservative or separated residue actually used/generated requires its own concrete card where relevant to this role; these examples are alternatives, not a required recipe. Retain existing collection records and route-specific source evidence. Count-based planting records require measured or supplier-supported mass-per-unit when matched to a mass-based provider; retain count and mass as linked attributes rather than two purchases. Do not merge separate husk/shell or separate agents. A real mixed stream requires composition and recipient evidence and is counted once. Before completeness, record every applicable amount and native unit, link a compatible verified UUID or explicitly unresolved identity, preserve stock/return attribution, and normalize the attributable raw quantity once to the accepted reference output. Missing records are not zero; aggregate ranges are not individual-input defaults.	cp_cohort_inputs	Identity-specific exchanges and reconciled activity records

v_identity	reference and final outputs	Reject pierced/unreelable cocoons as reelable or a lot without grade/state/gate evidence; never bind fresh/unprocessed farm-gate UUID to dried, stifled or other-gate lot.	fao-cocoon-quality;fao-cocoon-drying
v_mass	fresh and dried lots	Require measured net mass and moisture per state; reconcile collection, grading, drying and final handover with sample and water-loss terms, not assumed dry yield.	fao-cocoon-characteristics;fao-cocoon-drying
v_routes	route deltas	Accept host, climate or mounting variant only with changed inventory, calculation, quality or validation evidence relative to managed parent; reject label-only route.	fao-cocoon-quality
v_attribution	multi-output and multi-period	Verify separately marketed outputs, waste, unfinished cohorts, shared assets and service periods; one cocoon mass and shared burden may have only one attributed handover.	fao-cocoon-quality
v_binding	flow cards	Resolve unresolved inputs to evidenced concrete UUIDs before TIDAS process exchange; leave other UUIDs unresolved until detail-confirmed.
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

10. Published Dataset Profile

Field	Value
dataset_role	State-specific foreground cocoon-production data package, not a published PCR release claim.
downstream_use	Secondary/background dataset for downstream silk chains; flow, process and lifecyclemodel projection after exchange identity resolution.
allowed_use	Compare same reelable state, species/grade and gate; compare fresh/dried only on measured moisture-normalized basis.
excluded_use	Proxy for raw silk, spun silk, pierced cocoon feedstock or reeling service; assumed fresh-to-dry conversion.
required_metadata	Cohort, species/strain, host source, grade, moisture, stifling operator/timing, reject destinations, gate, period and allocation.
required_quality_disclosure	Mass/moisture uncertainty, grade test, sampling, upstream data quality, unresolved identities and shared-asset allocation.
update_trigger	New host/strain or drying route, grade acceptance or gate change, exact UUID evidence or measured factors superseding provisional screens.
