1. Scope and Applicability

This PCR concerns managed-grown fresh cut whole Christmas trees at actual grower dispatch. It works backward from that reference product through the real producer route, including upstream planting-stock supply and the entire producing cohort, not only the cutting year. It does not prescribe a universal species, height, grade, cultivation duration or handling technology. Wild cutting, rooted or potted/replanting trees, artificial/decorated goods and retail, use and end-of-life are outside this scope.

OSU PNW684 establishes a managed multi-year crop whose species, origin and buyer grade affect cultivation; pruning boughs and failed trees require separate accounting. PNW6 establishes harvest and producer-side preparation/dispatch work, including cutting/yarding and conditional shaking or baling. Neither publication supplies PCR inventory defaults. The dispatch boundary is a producer handover, not a mandatory forest-roadside or retail gate.

Field	Value
What	Managed-grown fresh cut whole Christmas trees accepted at the actual grower dispatch gate
How much	1 kg accepted net fresh tree mass, excluding packaging, supports and foreign matter
How well	Actual species/provenance, height measurement convention and buyer grade acceptance are declared; no universal grade or shelf-life claim
How long or cycle	Actual multi-year cohort establishment-to-harvest phases plus cut-to-dispatch interval; replacements, failed trees and stocks carried between years are disclosed
reference_flow_link	`tree_dispatch`

Field	Value
Reference amount	1
Reference product flow	Fresh cut Christmas trees `ab8a7694-6ea2-4cce-b535-9358f74c1189`
Reference flow property	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`
Reference unit group	Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66`
Reference unit	kg
Required qualifiers	Managed-grown origin; actual species and provenance; contributing sites/blocks; cohort establishment and harvest dates; height convention and buyer grade; accepted net fresh mass and moisture/state at dispatch; actual tree count and measured count-to-mass relationship if count-based records are used; true dispatch actor/gate; preparation/holding status; packaging exclusion; rejected and co-product destinations

Declare all required qualifiers in the foreground package. One kilogram is an accounting reference, not a claim that a one-kilogram tree exists. Species/grade lots are not functionally interchangeable by mass alone; retain their actual mix and do not publish a configuration-free per-tree factor.

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 fresh dispatch tree lots on a calibrated scale under cp_dispatch; subtract separately measured package/support tare and rejected material. Use only positive accepted net tree mass.
fresh_state	planting_stock; standing_crop; grow_bough_goods; harvest_standing_feed; cut_trees; condition_tree_feed; prepared_trees; grade_tree_feed; accepted_grades; downgraded_goods; offspec_return; hold_tree_feed; held_trees; dispatch_tree_feed; tree_dispatch	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	Preserve actual fresh mass and measured moisture/state for each biological transfer; do not use a generic dry-matter or count conversion.
delivered_energy	grow_energy; harvest_energy; condition_energy; grade_energy; hold_energy; dispatch_energy	Energy	MJ	Only actual energy subexchanges use this rule; native service properties/units remain separate. Preserve original fuel quantity, fuel identity and heating-value convention; distinguish electricity from fuels. Convert electricity using the exact unit equality 1 kWh = 3.6 MJ, not a heat-generation efficiency.
material_basis	grow_materials	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	Preserve each fertilizer formulation mass and declared nutrient basis separately, each plant-protection product and active ingredient separately, and purchased water apart from natural abstraction; never sum unlike substances as one concrete flow.

Count-only invoices are not mass observations. Collect paired actual count, species/height-grade and accepted net mass of the same lot; reconstruct the actual total attributable activity for that lot, then divide by its accepted net mass. If those records do not exist, mass-normalized data production is incomplete. No assumed average tree mass, standard rotation, yield or moisture factor is allowed.

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	Actual managed planted cohort with traceable nursery planting-stock supply, establishment, replacement and annual cultivation history
starting_condition_role	Foreground crop production start; nursery supply remains required upstream technosphere coverage
product_classification_scope	Narrower managed-grown fresh cut whole-tree portion of CPC 03241, not all origins or presentations
recursive_input_rule	Purchased trees of the same category retain supplier upstream datasets and genuine receipt/handling; do not reopen their production in this foreground or count them as own-grown reference without origin disclosure
upstream_dataset_requirement	Nursery stock, supplied materials, energy and attributable assets/services require compatible upstream datasets with declared geography, time, state and unit; missing coverage is a gap, never zero
disclosure	Actual cohort periods/sites, biological and package stocks, upstream coverage, bypassed optional nodes, actual handovers, shared assets, rejects, co-products, direct releases and exclusions

Boundary Rules

rule_id	Applies to	Rule	source_ids
bound_cohort	grow; harvest	Include establishment, all cultivation years, replacements and failed-tree burdens attributable to harvested lots; identify remaining living stocks and termination rather than placing all lifetime burdens in one harvest year.	osu-christmas-culture
bound_actual_path	all processes	Use the actual graph: grow to harvest; harvest directly to grade or through condition; grade directly to dispatch or through hold. Rework returns link to the originating off-spec lot and actual receiving node. Do not invent bypassed activity or treat transfers as additional final sales.	osu-christmas-harvest
bound_gates	dispatch	End at actual producer acceptance/loading handover; include producer-side movement and loading once, exclude carrier distribution/retail/use/end-of-life. Declare any geographically distinct grower handling site and include its connecting transport once.	osu-christmas-harvest
bound_direct	grow; all processes	Managed biomass is not a wild whole-tree elementary removal. Record actual environmental abstractions and direct substance releases with receiving media; model biogenic carbon only with an explicit reviewed balance/method, separate stored carbon from sequestration credits and disclose incomplete terms.
bound_assets_sites	all processes	Index every contributing field/block/nursery interface/yard, shared tractor, shed or irrigation service and each consuming node/year. Include attributable upstream asset/services once using observed causal usage and actual service periods; disclose residual unmatched coverage.
bound_optional	condition; hold; dispatch	Actual preparation, fresh holding and package presentation do not automatically create a new tree identity. A distinct physical transformation or incompatible state needs separate identity evidence; attached package mass never enters tree reference mass.
bound_identity_reuse	all own-grown fresh tree transfers	Reusing one compatible flow UUID identifies the physical fresh product only. Preserve actual upstream/downstream process links and measured internal quantities; do not reload a complete farmgate background dataset at every own-grown internal node, count an intermediate transfer as completed dispatch, or count the same lot as a second sale. External purchases retain their actual supplier coverage separately.
`boundary_direct_release_coverage`	`grow`; `harvest`; `condition`; `grade`; `hold`; `dispatch`	Reconcile on-site combustion, actual applications and fugitive releases/leaks at every activated node through unique activity-substance-receiving-medium records in cp_direct_release_grow; cp_direct_release_harvest; cp_direct_release_condition; cp_direct_release_grade; cp_direct_release_hold; cp_direct_release_dispatch. Upstream production of purchased fuel or chemicals does not replace emissions from their use on site; verify coverage and avoid double counting the same activity inside a supplier service. Evidence must support non-activity; missing data are not zero. This obligation does not expand the existing product gate or downstream-use boundary and does not presume combustion, fertilization, chemicals or equipment occur.

Select the route from actual incoming state and ownership. Qualified purchased harvested, extracted, prepared or graded feed may enter at its real receiving node; completed upstream operations are not mandatory foreground operations and standing stock or biological resources must not be charged again. Receiving cards record actual material, grade, wet/dry basis, receipt gate, upstream dataset and process coverage; add the actual receiving exchange if none exists. Bypass does not remove upstream burdens; actual operations cannot be skipped and final reference product, quality and gate remain unchanged.

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
`grow`	Managed crop establishment and full-cohort cultivation	conditional	Managed cultivation is owned inside the foreground for the represented cohort. Purchased fresh cut trees bypass growth while retaining verified managed-origin and matching upstream cultivation burdens.	managed biological production	per 1 kg reference flow
`harvest_to_dispatch`	Aggregated harvest-to-producer-dispatch inventory	required	Final acceptance/dispatch is mandatory; activate the other actual activities below without repeating completed purchased-feed operations	Aggregate boundary for harvesting, preparation, grading, holding and dispatch	per 1 kg reference flow

The inventory has two nodes: grow and harvest_to_dispatch. The latter aggregates the five actual activities harvest, condition, grade, hold and dispatch without removing their operations, losses, sites, direct releases or multi-year attribution duties. Their original identifiers remain activity labels in collection protocols, row ids and rules, not five separate inventory nodes. Cancel matched internal transfer pairs only within this aggregate boundary; retain the unallocated measured ledger, stocks and rework, and never force internal quantities to equal accepted net dispatch mass. Standing-tree receipts, external purchased cut trees, materials, services, wastes, direct releases and final outputs crossing the boundary retain complete flow cards. A later subdivision into separate unit processes must reconstruct both sides of every internal transfer and be validated independently; this aggregate projection is not a validated disaggregated process graph.

Activities and activation inside the aggregate node

activity_id	activity_name	inclusion	inclusion_condition	role	quantitative_reference
`harvest`	Cutting and yarding	conditional	Actual cutting or yarding occurs inside the foreground. Purchased already cut/yarded trees bypass the corresponding completed operations with matched upstream coverage.	harvest	per 1 kg reference flow
`condition`	Primary shaking and preparation	`conditional`	Actual shaking or primary preparation occurs	primary conditioning	per 1 kg reference flow
`grade`	Buyer grade and destination determination	`required`	Always within the declared actual route	grading and sorting	per 1 kg reference flow
`hold`	Bounded fresh protective holding	`conditional`	Actual protected holding occurs before dispatch	preservation and stabilization	per 1 kg reference flow
`dispatch`	Protective presentation and grower dispatch	`required`	Always within the declared actual route	packaging and presentation; producer dispatch	per 1 kg reference flow

Process: Managed crop establishment and full-cohort cultivation (`grow`)

Node grow must complete the direct-release coverage reconciliation in cp_direct_release_grow. Expand each actual substance/medium into an output elementary exchange at this node with a measured or evidence-calculated amount; link existing emission cards to the same event record rather than duplicating them. Distinguish non-occurrence, verified upstream-service coverage and missing evidence; an empty elementary-flow group does not satisfy this requirement.

Managed standing trees pass to harvest; establishment, replacements and every cultivation year belong to the same cohort. Fertilizers, irrigation, plant protection and training are conditional actual management inputs. Pruning boughs may be independent intended goods, returned residues or waste.

Inputs

Electricity at the equipment supply point (`grow_energy_electricity`)

Collection scope and applicability for grow_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.

Identify each actual fuel or electricity exchange in its own conditional card and preserve its delivered-energy basis. Activation requires actual use.

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.

Selected flow: Alternating current 455f0ef5-6118-4f2b-a3f5-1f75e0afe3ca

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.

Waste flows

Elementary flows

Process: Aggregated harvest-to-producer-dispatch inventory (`harvest_to_dispatch`)

Activity harvest must complete the direct-release coverage reconciliation in cp_direct_release_harvest. Expand each actual substance/medium into an output elementary exchange at this node with a measured or evidence-calculated amount; link existing emission cards to the same event record rather than duplicating them. Distinguish non-occurrence, verified upstream-service coverage and missing evidence; an empty elementary-flow group does not satisfy this requirement.

Cutting separates the living managed crop from fresh cut whole trees. Yarding ends at the actual grower handling point; it does not imply a new sale or a wild-resource-removal flow. Keep cut losses, uncropped standing stock and incidental material distinct.

Activity condition must complete the direct-release coverage reconciliation in cp_direct_release_condition. Expand each actual substance/medium into an output elementary exchange at this node with a measured or evidence-calculated amount; link existing emission cards to the same event record rather than duplicating them. Distinguish non-occurrence, verified upstream-service coverage and missing evidence; an empty elementary-flow group does not satisfy this requirement.

Fresh cut whole trees enter; actual shaking or basal tidying prepares the same fresh product for grading. Removed needles and trimmings retain their real return, use or disposal destination. If absent, bypass without inventing an intervention or its inputs.

Activity grade must complete the direct-release coverage reconciliation in cp_direct_release_grade. Expand each actual substance/medium into an output elementary exchange at this node with a measured or evidence-calculated amount; link existing emission cards to the same event record rather than duplicating them. Distinguish non-occurrence, verified upstream-service coverage and missing evidence; an empty elementary-flow group does not satisfy this requirement.

Enumerate each accepted species/height/grade lot, a separately sold downgraded lot, off-spec trees awaiting identified return/rework, and actual discarded material. Buyer acceptance defines the dispatch reference; the PCR imposes no universal grade threshold. Grading is not another physical tree transformation.

Activity hold must complete the direct-release coverage reconciliation in cp_direct_release_hold. Expand each actual substance/medium into an output elementary exchange at this node with a measured or evidence-calculated amount; link existing emission cards to the same event record rather than duplicating them. Distinguish non-occurrence, verified upstream-service coverage and missing evidence; an empty elementary-flow group does not satisfy this requirement.

Accepted fresh trees enter a measured holding interval and leave in the same declared fresh state. Shade, cooling or water inputs are not compulsory: record only actual interventions, depletion, drying loss and rejected trees. This is not intentional drying or a shelf-life guarantee.

Activity dispatch must complete the direct-release coverage reconciliation in cp_direct_release_dispatch. Expand each actual substance/medium into an output elementary exchange at this node with a measured or evidence-calculated amount; link existing emission cards to the same event record rather than duplicating them. Distinguish non-occurrence, verified upstream-service coverage and missing evidence; an empty elementary-flow group does not satisfy this requirement.

Accept trees after the actual upstream path; netting, string, tags and supports are recorded only when used. Separate reusable equipment from one-way packaging and net tree mass from package mass. Loading ends at the actual grower dispatch acceptance event; downstream carrier distribution is excluded.

Actual receipt of purchased fresh cut trees (`purchased_cut_tree_feed`)

Record only purchased fresh cut trees actually crossing the aggregated harvest-to-dispatch boundary. Retain actual receipt state, activity entry point and separately matched supplier upstream coverage. Own-grown transfers inside this boundary are not this input; do not repeat completed harvesting or preparation.

Reference normalization identity: Let R > 0 kg be the actual accepted net final product mass measured under the linked collection protocol for the same lot, boundary and period, excluding packaging, rejects and other products. Its normalized reference output is (R/R) × 1 kg = 1 kg. The 1..1 interval verifies that identity; it does not describe yield or uncertainty in the underlying measurement of R. Retain those measurements and their uncertainty independently.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule
alloc_output_set	intended outputs	Enumerate every accepted tree grade, separately intended pruning bough good and independently sold downgraded good with its actual handover. Subdivide directly measured activities first; internal living/tree/package transfers are not additional sale outputs.
alloc_shared_outputs	shared cohort burden	Where subdivision cannot resolve shared tree/bough/grade production, collect the actual causal usage or biological-output relationship, declare and justify a PCR-specific allocation method and retain a sensitivity alternative. Economic allocation requires contemporaneous comparable actual prices and justified failure of physical attribution; no equal shares or universal factors. Missing material evidence blocks finalization.
alloc_years	grow; all periods	Carry establishment and annual inputs/asset usage by actual cohort and year; allocate harvested lots, still-living stock, failed stock and replacements once using the recorded production relationship. Repeated harvests cannot each absorb the same establishment burden, and failed crop burdens cannot vanish.
alloc_assets_runs	all processes	Attribute each shared asset/service and cleaning/changeover event once across its real consuming nodes, sites, years and lots using measured service use. Maintain a ledger of assigned and residual burden; no independent full-charge in every node.
alloc_returns	offspec_return; all rejects	Returns keep prior attributed burdens and acquire actual additional work once. Regrade/retrim losses retain their actual treatment or return route. Rejected material never enters accepted mass or produces an unsupported avoided-product credit.
alloc_sites	contributing sites	Aggregate by summing compatible attributable quantities and dividing by summed accepted net mass, retaining species/grade/cohort mix and site coverage; do not average site intensities without weights or mix uncovered sites into zero burden.

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.

Missing records never establish zero or exclusion. `dispatch_waste_specific_output`: Activity owner: dispatch. Conditional collection requirement for actual removed material sent to treatment; preserve organic, package and hazardous identities. Returned field residues and intended goods are not automatically waste. Measured attributable quantity under cp_dispatch, divided by accepted net dispatch mass; retain the actual internal quantity before normalization 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.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output
normalize_lot_mass	Separate physical-ledger and burden normalization	R is the positive final accepted net fresh cut-tree dispatch mass in kg for the same boundary, lot and period, excluding co-products, internal transfers and unaccepted stocks. Report original material, co-product and transfer totals Q as q_phys = Q/R without a burden-allocation share. Report environmental burdens B as b_ref = B_attributed/R only after one evidenced direct/output/period/asset attribution. Do not divide final-reference intensities again; cancel paired internal transfers only at whole-package aggregation, not as additional final outputs.	unallocated physical totals Q; burdens B and attribution records; matched positive reference mass R	exchange amount per 1 kg reference flow
derive_count_records	count-based source records	Collect paired actual count and accepted net fresh mass for the same species/height-grade lot; reconstruct actual activity totals from source records, then use normalize_lot_mass. A bare count-only invoice is incomplete, not an assumed kilogram conversion.	paired actual count/mass; lot/species/height-grade; original activity records	traced lot activity totals and count-to-mass relationship
reconcile_stocks	each biological and package handover	Reconcile actual input, output, return, remaining stock and loss separately for each state/period; fresh moisture and dry/biogenic terms are not interchangeable. Investigate residuals rather than inventing a balancing release.	indexed masses/counts; actual moisture/state; returns; loss; stock	disclosed reconciliation and unexplained residual
energy_unit_equality	energy cards	Convert measured electricity kWh to MJ by multiplying by 3.6; retain original records and actual fuel heating-value convention separately. This is unit conversion, not electricity-to-heat equivalence.	actual electricity kWh; actual fuel records	delivered-energy quantities with identities retained
attribution_ledger	all shared burdens	Reconcile the total source burden to allocations across actual output/site/cohort/year/asset/lot consumers and a disclosed residual. Record rework added burden separately from carried burden.	original burden; actual usage/output evidence; declared allocation	assigned and residual burdens without duplicates
`calculate_direct_release_ledger`	`grow`; `harvest`; `condition`; `grade`; `hold`; `dispatch`	For each unique event, substance and medium, obtain raw release E from measurement or the cited applicable method using activity A and a compatible factor EF; use E = A * EF only for a genuinely simple-factor method, after checking units and abatement scope. Do not add different substances/media; retain an unallocated raw-release ledger. Divide attributed burden totals once by matched positive final reference quantity R; do not renormalize final-reference intensities or allocate a shared event twice. Unexplained material residuals are not automatically emissions and missing factors are not zero.	cp_direct_release_grow; cp_direct_release_harvest; cp_direct_release_condition; cp_direct_release_grade; cp_direct_release_hold; cp_direct_release_dispatch; existing emission cards; supplier coverage; reference quantity	Node/substance/medium-specific raw and attributed amounts and unresolved gaps
`aggregate_internal_transfers`	cut_trees; prepared_trees; accepted_grades; held_trees; condition_tree_feed; grade_tree_feed; hold_tree_feed; dispatch_tree_feed; offspec_return	Record paired event-level fresh mass T in kg, activity, lot and state. For positive final dispatch mass R retain T/R × 1 kg in the internal ledger; never force T=R. The four normal fresh-tree handoffs retain verified cut-tree identity ab8a7694-6ea2-4cce-b535-9358f74c1189; downgraded/rework material needs separate compatible identity confirmation, not role-based inheritance. Cancel each pair once within the aggregate boundary, never period stocks, losses, externally sold downgraded goods or actual external purchases. Rework adds only its actual new activity burden without duplicating carried burdens.	cp_harvest; cp_condition; cp_grade; cp_hold; cp_dispatch; transfer_id; paired records	unallocated measured transfer ledger and aggregate inventory without duplicate internal exchanges
`grow_land_specific_exchanges`	`grow`	Enumerate actual land occupation and each evidenced land transformation separately, with site, land class, from/to state, area and period. Occupation uses area-time; transformation uses area and separate from/to identities under the selected method. Instantiate one concrete elementary exchange per identity and unit; never add the two dimensions, infer transformation from planting, or assume zero land burden from wild origin. Retain the linked protocol and actual process attribution. Reconstruct each attributable raw numerator on its recorded stage basis, then normalize once to the matched accepted reference output. Missing identity, quantity, unit or destination blocks dataset completeness; absence requires evidence, not an assumed zero.	`cp_grow`	Separate atomic exchanges; completeness required

System boundary rules · 9

Rule ID	Applies to	Rule	Source IDs
`bound_cohort`	grow; harvest	Include establishment, all cultivation years, replacements and failed-tree burdens attributable to harvested lots; identify remaining living stocks and termination rather than placing all lifetime burdens in one harvest year.	osu-christmas-culture
`bound_actual_path`	all processes	Use the actual graph: grow to harvest; harvest directly to grade or through condition; grade directly to dispatch or through hold. Rework returns link to the originating off-spec lot and actual receiving node. Do not invent bypassed activity or treat transfers as additional final sales.	osu-christmas-harvest
`bound_gates`	dispatch	End at actual producer acceptance/loading handover; include producer-side movement and loading once, exclude carrier distribution/retail/use/end-of-life. Declare any geographically distinct grower handling site and include its connecting transport once.	osu-christmas-harvest
`bound_direct`	grow; all processes	Managed biomass is not a wild whole-tree elementary removal. Record actual environmental abstractions and direct substance releases with receiving media; model biogenic carbon only with an explicit reviewed balance/method, separate stored carbon from sequestration credits and disclose incomplete terms.
`bound_assets_sites`	all processes	Index every contributing field/block/nursery interface/yard, shared tractor, shed or irrigation service and each consuming node/year. Include attributable upstream asset/services once using observed causal usage and actual service periods; disclose residual unmatched coverage.
`bound_optional`	condition; hold; dispatch	Actual preparation, fresh holding and package presentation do not automatically create a new tree identity. A distinct physical transformation or incompatible state needs separate identity evidence; attached package mass never enters tree reference mass.
`bound_identity_reuse`	all own-grown fresh tree transfers	Reusing one compatible flow UUID identifies the physical fresh product only. Preserve actual upstream/downstream process links and measured internal quantities; do not reload a complete farmgate background dataset at every own-grown internal node, count an intermediate transfer as completed dispatch, or count the same lot as a second sale. External purchases retain their actual supplier coverage separately.
`boundary_direct_release_coverage`	grow; harvest; condition; grade; hold; dispatch	Reconcile on-site combustion, actual applications and fugitive releases/leaks at every activated node through unique activity-substance-receiving-medium records in cp_direct_release_grow; cp_direct_release_harvest; cp_direct_release_condition; cp_direct_release_grade; cp_direct_release_hold; cp_direct_release_dispatch. Upstream production of purchased fuel or chemicals does not replace emissions from their use on site; verify coverage and avoid double counting the same activity inside a supplier service. Evidence must support non-activity; missing data are not zero. This obligation does not expand the existing product gate or downstream-use boundary and does not presume combustion, fertilization, chemicals or equipment occur.
`system_boundary_rule_9`	foreground_system_boundary	Select the route from actual incoming state and ownership. Qualified purchased harvested, extracted, prepared or graded feed may enter at its real receiving node; completed upstream operations are not mandatory foreground operations and standing stock or biological resources must not be charged again. Receiving cards record actual material, grade, wet/dry basis, receipt gate, upstream dataset and process coverage; add the actual receiving exchange if none exists. Bypass does not remove upstream burdens; actual operations cannot be skipped and final reference product, quality and gate remain unchanged.

Allocation rules · 7

Rule ID	Applies to	Rule
`alloc_output_set`	intended outputs	Enumerate every accepted tree grade, separately intended pruning bough good and independently sold downgraded good with its actual handover. Subdivide directly measured activities first; internal living/tree/package transfers are not additional sale outputs.
`alloc_shared_outputs`	shared cohort burden	Where subdivision cannot resolve shared tree/bough/grade production, collect the actual causal usage or biological-output relationship, declare and justify a PCR-specific allocation method and retain a sensitivity alternative. Economic allocation requires contemporaneous comparable actual prices and justified failure of physical attribution; no equal shares or universal factors. Missing material evidence blocks finalization.
`alloc_years`	grow; all periods	Carry establishment and annual inputs/asset usage by actual cohort and year; allocate harvested lots, still-living stock, failed stock and replacements once using the recorded production relationship. Repeated harvests cannot each absorb the same establishment burden, and failed crop burdens cannot vanish.
`alloc_assets_runs`	all processes	Attribute each shared asset/service and cleaning/changeover event once across its real consuming nodes, sites, years and lots using measured service use. Maintain a ledger of assigned and residual burden; no independent full-charge in every node.
`alloc_returns`	offspec_return; all rejects	Returns keep prior attributed burdens and acquire actual additional work once. Regrade/retrim losses retain their actual treatment or return route. Rejected material never enters accepted mass or produces an unsupported avoided-product credit.
`alloc_sites`	contributing sites	Aggregate by summing compatible attributable quantities and dividing by summed accepted net mass, retaining species/grade/cohort mix and site coverage; do not average site intensities without weights or mix uncovered sites into zero burden.
`allocation_rule_7`	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 · 10

Rule ID	Applies to	Rule
`valid_reference`	tree_dispatch	Reference link identifies the sole actual accepted dispatch product output and 1 kg net fresh mass; all qualifiers and actual support identities are declared and package/reject mass excluded.
`valid_cohort`	grow; harvest	Check complete cohort/year/failed/replacement and remaining-stock accounting; upstream nursery/material/energy/asset gaps remain disclosed and prevent unsupported zero estimates.
`valid_path`	all processes	Check actual optional-node bypasses, transfer input/output links, returns and handovers; same fresh product may reuse a compatible verified identity, but living stock/seedlings cannot inherit the cut-tree UUID.
`valid_outputs`	all outputs	Enumerate accepted grades, downgraded goods, bough goods, off-spec return, field residues and waste with real destination and attribution. Exclude unresolved rejects from reference mass.
`valid_attribution`	every shared ledger	Reconcile sites, periods, output sets, assets and handling campaigns; check cleaning/changeover events and no repeated full-burden allocation or unsupported substitution credits.
`valid_units`	all rows	Check actual paired count/mass conversion, one net dispatch denominator, fresh moisture/state and native substance/energy/service units; do not equate per-tree records directly to per-kg values.
`valid_bindings`	all actual exchanges	Final dataset exchanges require independently verified specific UUIDs/property/unit; unresolved candidate identities and heterogeneous umbrellas cannot be silently accepted or supplied from a screen.
`valid_bilingual`	all cards	Preserve EN/ZH process/direction/type/row ids, actual meaning, amounts/bases, bindings and Range metadata; regenerate the projection after canonical edits and inspect performed/skipped check coverage.
`validate_direct_release_coverage`	grow; harvest; condition; grade; hold; dispatch	For every activated node, reconcile its activity list against cp_direct_release_grow; cp_direct_release_harvest; cp_direct_release_condition; cp_direct_release_grade; cp_direct_release_hold; cp_direct_release_dispatch: each relevant event must have quantified concrete elementary exchanges, evidenced upstream-service coverage, or evidenced absence of the activity. Missing/unknown is not zero and blocks data-package completeness. Check each actual substance/medium amount, method/factor units, concrete UUID and existing-card/service coverage for omissions or duplication; empty groups, purchased-electricity upstream emissions or another node's single CO2 card do not replace this node's on-site reconciliation. Shared-asset services must not create duplicate physical release events.
`validation_rule_10`	foreground_dataset_conformance	Reconcile required/conditional activation and upstream coverage against incoming state at each node; purchased completed-state feed must not duplicate growth, harvest or preparation. Equal classification does not replace state and gate matching.
