1. Scope and Applicability

This PCR covers fresh whole edible hypogeal truffle fruiting bodies gathered from untended terrestrial sources and supplied at a declared primary handover. Intended cultivation, inoculated orchards, irrigation or substrate/host management for truffle production are outside scope even when commercially called wild. Source tenure or access rights alone do not prove untended origin. Species/edible-use acceptance must be evidenced; this PCR does not certify food safety or ready-to-eat use. Frozen, dried, brined, cooked, sliced/prepared or extracted products and ordinary epigeal mushrooms are excluded.

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	Weigh accepted net fresh whole fruiting bodies on a calibrated scale using cp_handover; exclude tare, soil, foreign matter and rejected goods. Do not convert to dry matter without separately measured moisture.
`native_service_units`	service and energy rows	Actual exchange property	Native unit	Preserve native supplier quantities, including MJ/kWh, service hours, mass-distance or asset shares; document conversions separately. Service-hour screens do not justify replacing tonne-kilometres or multiplying dissimilar units.
`foreign_mass`	truffle and incidental matter rows	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	Maintain paired gross/net/soil/tare records and wet-state ledger; water or soil gained or removed cannot be silently counted as edible truffle yield.

rule_id	Applies to	Required property	Required unit	Rule
`provisional_range_evidence_policy`	all Ranges and actual exchanges	compatible property of each actual exchange	native unit of each actual exchange	All reasoned_estimate Ranges are provisional review prompts for this candidate method, not measured distributions, allowable losses, default quantities or emission factors. Never clip, backfill or force actual records to fit them; investigate state, units, boundary, stocks and evidence when exceeded. Before completing a data package, determine actual quantities and uncertainty from traceable measurements or applicable reviewed quantitative sources. Retain missing amounts, factors and flow identities as gaps that block completeness claims; passing a range screen is not evidence.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Untended fruiting bodies in their natural source for self-gathering, or documented already gathered purchased fresh feed
starting_condition_role	Natural source to collector interface, or upstream technosphere handover; declared per source portion
product_classification_scope	Fresh-primary truffle subset of CPC 03233; not all states or cultivation
recursive_input_rule	Purchased already gathered same-category feed is a product input linked to non-overlapping upstream dataset; never regenerate its search/removal burden or truncate to zero
upstream_dataset_requirement	Require matching wild origin, species/state/gate and documented prior removal/preparation/transport; report missing evidence rather than infer an orchard proxy
disclosure	List all source sites/collectors, periods, actual node activations/bypasses, purchased fractions and inclusive suppliers; final acceptance always applies

rule_id	Applies to	Rule	source_ids
`source_ownership`	collection	Targeted search/extraction owns harvesting and natural removal together; do not invent managed biological production or add removal again at cleaning. Soil disturbance is documented separately from actually exported foreign matter.	`fao-truffle-harvesting`
`conditional_route`	all nodes	Use actual lot events to activate cleaning/grading or fresh holding/cooling. Record the input/output state and handover when bypassed. Unknown intervention is not a bypass. Pack only actual materials and reuse; downstream distribution and consumer processing remain outside the primary gate.	`fao-fresh-fungi-handling`
`owned_ledgers`	shared services	Declare batch/trip/season mode, each run/changeover, failed trips, source-site contributions, shared vehicles/tools/animal assistance/cold-room consumers and service periods. Record replacement and termination events. Inclusive purchased services own embedded feed, energy, care and emissions; direct ledgers cover only nonincluded responsibilities.	`fao-truffle-harvesting`

`conditioning`	Primary cleaning and grade separation	`conditional`	Actual soil removal, cleaning or grade separation before fresh handover	Raw collected to prepared fresh grade, with destination ownership	per 1 kg reference flow
`holding`	Fresh holding and actual cooling	`conditional`	Actual holding/cooling before primary handover, without freezing or drying	Retain the fresh state and record actual residence conditions	per 1 kg reference flow
`handover`	Primary packaging and net acceptance	`required`	Every accepted reference lot; packaging only when actually used	Net accepted fresh whole fruiting bodies at actual primary gate	per 1 kg reference flow

All cards use actual recorded amounts. Every nonreference Range is a deliberately broad provisional reasoned screening estimate, not a default, a legal limit, a measured yield or an enforcing ceiling. Values outside a screen prompt review but are not rejected automatically. Zero requires evidence of actual absence; missing/unknown data remain a gap. Service screens are only hours for a service-time exchange; other service units need their own declared evidence, never a guessed conversion.

Process: Targeted search, extraction and source handover (`collection`)

Inputs

Product flows

Electricity at the equipment supply point (`collection_energy_electricity`)

Collection scope and applicability for collection_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.

One energy umbrella for actual fuels, electricity or supplied heat; keep original carrier/provider/state, unit and conversion evidence. Purchased service energy must not be added a second time. Unknown carrier use cannot be set to zero.

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.

This binding is alternating current at the use point with supply technology, voltage and provider unspecified. Confirm actual AC supply; DC requires a different identity. The database reference is 1 MJ: preserve meter kWh and convert once using 1 kWh = 3.6 MJ when linking reference quantities. Internal generation links to its foreground generator, without an additional purchased-electricity burden.

Untended fresh truffle fruiting bodies removed from nature (`collection_natural_truffles`)

Mass of actual targeted edible fruiting bodies at removal, excluding soil and mycelium left in place. Natural-source removal is accounted once with search/extraction; legal land ownership does not decide this environmental/technosphere interface. Purchased already gathered feed has upstream removal and must not be charged again. No automatic fungal growth carbon credit.

Fresh wild truffles as collected at source handover (`collected_truffles`)

Species-qualified fresh collected load handed to conditioning, holding or primary acceptance; separately weigh truffle fruiting bodies and attached foreign matter so gross load is never mistaken for edible reference mass. Targeted extraction is distinct from adjacent cleaning and from intentional cultivation.

corrugated board boxes (`handover_materials_box`)

Only for actual corrugated boxes at this node.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule
`output_attribution`	all intended outputs	Enumerate reference and every independently intended grade/species/downstream-use output with actual handover. First subdivide separately measured trip/node services; next use a demonstrated causal physical driver (e.g. search time, load-distance, cooling occupancy) for joint burdens; only when no physical driver is defensible use disclosed revenue shares from the same site-season. Record quantities, prices/period and uncertainty. No automatic substitution credit.
`trip_period_asset`	shared services	Attribute unsuccessful trips to the declared site-season effort serving actual intended products; do not divide by zero-output trips or drop them. Link asset/feed/training/care burdens to actual consuming nodes and service periods, including replacements and termination, and retain unique event keys. Sum each burden once over outputs and periods.
`reject_loops`	all rejects and returns	Off-spec/spoiled goods exit as actual other intended goods or actual waste; record producing node and recipient. Recleaning returns link handover/holding to conditioning with retained burdens and incremental inputs only. Do not count each passage as newly removed or accepted output. Waste disposal receives its actual attributable burden, never an automatic zero or recovered credit.

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

Material and service identification requirements

Identify each actual material or independently supplied service from supplier and activity records; record composition/specification, quantity, unit, node and period separately. Add one concrete exchange per identity before dataset completion; these requirements are not a single exchange. Reconcile with existing cards and inclusive services to avoid duplication. Allocate reusable assets over evidenced use and preserve physical quantities; normalize once to the matched final reference output. Missing identity or use evidence is a completeness gap, not zero use. Conditional examples below are not an exhaustive bill of materials and do not prescribe use or amounts.

requirement_id	collection_protocol_id	Required scope
`collection_materials_identification`	`cp_collection`	actual collection tools, carrying containers and supplies; for truffles include animal feed/care only when animal assistance occurred
`conditioning_materials_identification`	`cp_conditioning`	actual cleaning water, named cleaning formulations and handling supplies; no universal washing or chemical use is assumed
`holding_materials_identification`	`cp_holding`	actual fresh-holding hygiene supplies, cooling media and storage materials, excluding drying, freezing and chemical-preservation routes
`handover_materials_identification`	`cp_handover`	actual protective containers, wrapping, labels and acceptance hygiene supplies; keep package tare separate from edible net mass

`cp_collection`	collection	Every actual card and net reference mass	Paired mass/activity ledger	event_id; node; collector; site; species; wild-origin evidence; trip including failed; lot; grade; gross; tare; soil; accepted_net_mass; opening/closing stocks; returns; recipient/use; actual energy/material/service/provider/native_unit; inclusive supplier scope; animal assistance/feed/training/care/travel; asset/service period/replacement/termination; named emission substance/particle/compartment; measured quantity or activity and factor source	Weigh accepted net fresh whole fruiting bodies on calibrated scales after separate soil/tare determination. Pair dispatch and receipt records for every node; record unsuccessful searches, residence times and actual cooling, service invoices/meters/feed records, unique asset events and named emissions via measurement or documented activity-factor method. Reconcile species/source proof with acceptance. `collection_services_specific_input`: One collection-service umbrella records actual access/search/extraction, attributable approach and collected-load transfer, tools/vehicles and reusable collection assets. Actual trained-animal assistance includes attributable training, care and travel only when used, with observed service periods, replacement/termination and feed/provider-inclusion linkage. Record service-native units; h is only a service-time screen, not a tonne-kilometre conversion. Measure the attributable amount, retaining actual identity and destination; divide by the accepted net reference mass using cp_collection. Unknown is a data gap, not zero. 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. `collection_emissions_specific_emission`: Conditional direct-emission umbrella: require actual substance or particle size, receiving compartment, activity and measurement or factor method. Report combustion, service leaks or identified product moisture/respiration only when attributable and established; an unexplained mass deficit is not a pollutant or automatically water vapour. Do not duplicate emissions embedded in inclusive supplier services. Measure the attributable amount, retaining actual identity and destination; divide by the accepted net reference mass using cp_collection. Unknown is a data gap, not zero. This is a mandatory emission-identification requirement, not an aggregate elementary exchange. Identify every applicable substance and actual receiving compartment separately, with compatible units, measured activity or justified calculation method, parameter applicability and uncertainty. Preserve the original operation, period, allocation and final-reference normalization. Reconcile direct and indirect pathways and upstream coverage once; do not substitute total nitrogen, total combustion emissions or a generic pollutant for a named compound. Separately document actual environmental returns, with their material and destination, if relevant. Before dataset completeness create each required specific exchange, confirm a compatible UUID or explicitly retain its unresolved identity. Missing records do not establish zero or inapplicability. `fao-truffle-harvesting` `collection_other_goods_specific_output`: Only actual intended nonreference truffle grades or species sharing the declared trip leave with their state, use, recipient and measured amount. Record the joint-search burden decision; unrelated shared-trip products have their own non-overlapping system and service share. Do not invent other goods, classify disposed incidental matter as saleable output, or count collected_truffles again as an independent sale. Measure the attributable amount, retaining actual identity and destination; divide by the accepted net reference mass using cp_collection. Unknown is a data gap, not zero. This is a mandatory output-identification requirement, not an aggregate exchange. Preserve every actual co-product, reject, packaging waste and treatment stream in this operation. Before dataset completeness create separate cards for physically distinct streams, with actual material/state, quantity, destination and Product/Waste role. A genuinely mixed waste stream may remain one physically defined mixture with measured composition; do not invent separation or count its components again. Keep unlike units separate, retain the original allocation and reference normalization, and reconcile the output balance. Identify actual functions before co-product allocation; waste does not acquire a co-product share merely by having mass. Confirm a compatible UUID or explicitly retain its unresolved identity. Missing records never establish zero or exclusion. `fao-truffle-harvesting` `collection_waste_specific_output`: Actual rejected/damaged fruiting bodies, incidental matter sent to treatment and spent collection/animal-service materials leave to named external recipients. State identity, wet mass and event. Soil actually returned to nature belongs to collection_soil_return, not this waste exit; intended other truffle goods and retained stock are separate.

Reconcile species/source proof with acceptance. `conditioning_services_specific_input`: One conditioning-service umbrella records actual cleaning/grading, relevant lot transfer and allocated brushes, sorting space, scales or reusable assets.

Measure the attributable amount, retaining actual identity and destination; divide by the accepted net reference mass using cp_conditioning. Unknown is a data gap, not zero. Identify the actual input for this operation from supplier specifications, equipment and primary records. This is a mandatory collection requirement, not an exchange.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
`ledger_normalization`	all inventory rows	For each actual exchange divide its attributable recorded quantity by accepted net fresh truffle mass in kg. Retain native numerator units and allocation shares; final reference output is 1 kg. Reconcile opening stocks plus inputs with fresh goods, other goods, waste, named measured emissions and closing stocks without inventing missing material.	cp_collection; cp_conditioning; cp_holding; cp_handover	Exchange quantity per reference flow

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
`source_species`	all product lots	Evidence untended origin, accepted edible species/part and actual state/gate; ambiguous cultivation or unsafe/unidentified species blocks concrete dataset finalization.	cp_handover
`site_coverage`	all source sites and periods	Enumerate every collector/source/preparer and site-season contribution. Aggregate attributable numerator totals over compatible accepted net reference totals; document representativeness and exclusions. Never average intensities equally across unequal sites or omit failed efforts.	cp_handover
`identity_quality`	all concrete exchanges	Verify concrete identity, property/unit/provider/destination separately; energy/service units and unresolved conditional identities require actual supplier evidence. No screen substitutes for observations or unknowns.	cp_handover

9. Validation Rules

rule_id	Applies to	Rule
`reference_check`	fresh_truffles_handover	Reference name/link/state/gate and net calibrated mass must agree; the final output is 1 kg per 1 kg reference flow and no internal feed is fixed to this quantity.
`route_check`	all nodes	Verify actual node activations, bypass records, all incoming/outgoing handoffs, species/site origin and batches/periods. All rejected states require their producing-node route, recipient or retained stock; returns are linked to conditioning and cannot count twice as acceptance.
`closure_check`	all inventories	Reconcile wet truffle/soil/tare balances and stocks, actual output sets and attributed source-site/period/asset shares. Check inclusive supplier boundaries, failed trips, animal service duties and unique event ownership. Unknown mass deficit/absence is a disclosed gap, not a guessed emission, yield or zero.
`identity_range_check`	all cards	Every concrete exchange requires verified exact identity and support units; each Range has matching unit/basis/evidence. Provisional screens are non-enforcing, zero requires actual absence proof, and unknown state or unresolved support prevents final concrete use.

System boundary rules · 3

Rule ID	Applies to	Rule	Source IDs
`source_ownership`	collection	Targeted search/extraction owns harvesting and natural removal together; do not invent managed biological production or add removal again at cleaning. Soil disturbance is documented separately from actually exported foreign matter.	fao-truffle-harvesting
`conditional_route`	all nodes	Use actual lot events to activate cleaning/grading or fresh holding/cooling. Record the input/output state and handover when bypassed. Unknown intervention is not a bypass. Pack only actual materials and reuse; downstream distribution and consumer processing remain outside the primary gate.	fao-fresh-fungi-handling
`owned_ledgers`	shared services	Declare batch/trip/season mode, each run/changeover, failed trips, source-site contributions, shared vehicles/tools/animal assistance/cold-room consumers and service periods. Record replacement and termination events. Inclusive purchased services own embedded feed, energy, care and emissions; direct ledgers cover only nonincluded responsibilities.	fao-truffle-harvesting

Allocation rules · 4

Rule ID	Applies to	Rule
`output_attribution`	all intended outputs	Enumerate reference and every independently intended grade/species/downstream-use output with actual handover. First subdivide separately measured trip/node services; next use a demonstrated causal physical driver (e.g. search time, load-distance, cooling occupancy) for joint burdens; only when no physical driver is defensible use disclosed revenue shares from the same site-season. Record quantities, prices/period and uncertainty. No automatic substitution credit.
`trip_period_asset`	shared services	Attribute unsuccessful trips to the declared site-season effort serving actual intended products; do not divide by zero-output trips or drop them. Link asset/feed/training/care burdens to actual consuming nodes and service periods, including replacements and termination, and retain unique event keys. Sum each burden once over outputs and periods.
`reject_loops`	all rejects and returns	Off-spec/spoiled goods exit as actual other intended goods or actual waste; record producing node and recipient. Recleaning returns link handover/holding to conditioning with retained burdens and incremental inputs only. Do not count each passage as newly removed or accepted output. Waste disposal receives its actual attributable burden, never an automatic zero or recovered credit.
`allocation_rule_4`	foreground_burden_allocation	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.

Validation rules · 4

Rule ID	Applies to	Rule
`reference_check`	fresh_truffles_handover	Reference name/link/state/gate and net calibrated mass must agree; the final output is 1 kg per 1 kg reference flow and no internal feed is fixed to this quantity.
`route_check`	all nodes	Verify actual node activations, bypass records, all incoming/outgoing handoffs, species/site origin and batches/periods. All rejected states require their producing-node route, recipient or retained stock; returns are linked to conditioning and cannot count twice as acceptance.
`closure_check`	all inventories	Reconcile wet truffle/soil/tare balances and stocks, actual output sets and attributed source-site/period/asset shares. Check inclusive supplier boundaries, failed trips, animal service duties and unique event ownership. Unknown mass deficit/absence is a disclosed gap, not a guessed emission, yield or zero.
`identity_range_check`	all cards	Every concrete exchange requires verified exact identity and support units; each Range has matching unit/basis/evidence. Provisional screens are non-enforcing, zero requires actual absence proof, and unknown state or unresolved support prevents final concrete use.
