This is an attributional crop-production method for one physically defined food supply route. Site data remain to be collected; evidence supports the technical synthesis, not a measured farm inventory or approval. All below conditions and native-identity restrictions travel with the rules.

1. Scope and Applicability

Use only for Saccharina latissima cultivated on marine horizontal longlines from direct spore-seeded nursery twine through first food-quality release as fresh raw whole blades. The representative configuration combines the 2014 nursery method with the 2020 Connecticut raw-food harvest/cooling route; it is not claimed to be one SKU or farm. Purchased PES, filtered/UV-treated seawater, electric nursery cooling/light/aeration, workboat harvest and unsealed cold packaging are declared process choices. Actual equipment, cleaning and additions must be disclosed and each real additional exchange inserted. Avoid unsupported universal yields, moisture, chemical dose, energy or lifetime ranges. Fresh/frozen/dried/ground in CPC 04932 are distinct possible states; only the fresh whole route is covered here. No nutritional equivalence, safe shelf life or food certification is established.

classification_refs	CPC 3.0 04932; narrower product-state scope; mapping context only
covered_products	Farmed fresh raw whole Saccharina latissima for human food
excluded_products	Other taxa; wild food harvest; non-food biomass; extracts; frozen/dried/ground/blanched or reduced-oxygen routes
representative_product	Fresh sugar kelp blades from spore-seeded longline cultivation
production_route	Sorus collection; nursery inoculation and juvenile culture; longline deployment; maintenance; harvest; cooling and first food release
market_state	Fresh raw whole blades in unsealed cold packaging; no shelf-life claim

3. Reference Flow

Field	Value
What	Provide declared edible farmed fresh sugar kelp biomass
How much	1 kg first-released net wet tissue
How well	Species and provenance confirmed; documented food-suitability release; no water/ice/packaging inflation; independent dry matter and salt disclosure
How long or cycle	One declared cultivation cohort through first release; no universal storage duration or shelf-life equivalence
reference_flow_link	released_kelp

Field	Value
Reference amount	1
Reference product flow	Algae `eb76bd93-d5a5-4db2-bd08-388665f2eda5`
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	species Saccharina latissima; farmed origin and seed provenance; culture site and season; spore-seeded longline route; raw fresh whole blades; first-release gate and timestamp; Q net wet tissue and drainage method; independently measured dry matter and moisture; salt disclosure and attached-water exclusion; food-suitability evidence and destination requirements; harvest-water status; microbial and chemical test methods and detection limits; iodine and contaminant assessment; harvest-to-cooling time and temperature; unsealed packaging and allergen communication; cohort stock and inherited burden vectors; capital service attribution; actual postrelease service scope; uncertainty and identity restrictions; contrary native wild and unfit metadata with unknown owner intent; independent supply quality and no automatic wild/nonfood upstream dataset or provider

Required qualifiers must be retained in dataset metadata, process notes, reference-flow comments or equivalent fields. Generic Algae is not a food-specific match: it has generic aquatic biomass text, no CAS, no fixed grade/route/form/geography or moisture property, and one Mass reference. Its CPC label says wild/unfit, which is unresolved contrary classification metadata relative to this declared farmed/food use; native owner intent is unknown; the generic physical identity is used with the explicit restrictions on every adopted biomass card. Never infer farmed or edible status from the UUID.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
wet_basis	reference product	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	The reference is 1 kg newly first-released net wet S. latissima tissue. Weigh on calibrated scales after a declared repeatable drainage protocol; separately measure and exclude free/attached seawater, ice, twine, containers and fouling. Measure dry matter or moisture independently on representative tissue at a documented drying method; report residual salt separately. Never equate 1 kg dried algae with 1 kg fresh algae or assert nutritional/edible equivalence.
raw_units	all inventory rows	Mass or energy	kg or MJ	Retain raw readings with units, rates versus totals, temperature and uncertainty. Convert kWh by 3.6 MJ/kWh. Convert only actual rates by integrating over time; do not multiply an already integrated liquid/gas volume by duration. Use independently measured material-specific density and gas temperature/pressure/composition. Do not use secondary-property ratios to invent density or per-item mass.
whole_formula	pes	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	Whole purchased PES is one mass input. Assay, active salts, dry matter and carrier water are nested analytical quantities only. No reliable cross-supplier concentrate potency or LCI dose range is provided; collect each exchange raw amount and actual supplier specification.
single_basis	all inventory rows	Mass or energy	kg or MJ	Every final exchange has per reference flow basis. Data collection retains raw period amounts only; its aggregation label states the final destination basis and does not execute normalization. The sole §8 normalization derives the final amount after raw conversion, exchange-specific attribution and WIP burden reconciliation. Reference output remains exactly 1 kg.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Authorized fresh S. latissima sorus acquisition plus actual installed asset and supplier input production
starting_condition_role	foreground_starting_condition
product_classification_scope	CPC 3.0 04932 context; only the narrower fresh whole food crop described here
recursive_input_rule	Seeded twine is an internal stage; bought seed retains its full nursery burden. No infinite recursive edible-kelp input or burden-free bought finished crop
upstream_dataset_requirement	Match actual material/formulation, supply state, geography and energy boundary; retain technology and temporal representativeness and unresolved gaps
disclosure	Site; cohort; seed provenance; asset configuration; actual chemicals; raw water; food release; stock vectors; downstream service scope; exclusions

rule_id	applies_to	rule	source_ids
b_complete	cultivation_to_release	Include authorized sorus collection and nursery water treatment, enrichment, spore inoculation, lit/chilled/aerated nursery, seeded twine transport, installation, deployment, monitoring, thinning if actually needed, maintenance, retrieval, harvest, cooling, sampling, inspection, packaging and first food-quality release. Purchased seed does not erase its nursery chain: obtain complete supplier foreground/upstream inventory or explicitly retain the missing upstream burden. This route cannot begin at bought edible kelp.	ctsg-kelp-nursery-2014; ctsg-seaweed-food-hazards-2020
b_scope	fresh_food_route	Only cultivated S. latissima raw whole blades under documented food suitability are included. Wild-harvest food, S. japonica, Laminaria digitata, Gracilaria, microalgae, feed/fertilizer/bioremediation biomass, extracts and mixed taxa are excluded. Frozen, dried, ground, washed/blanched or reduced-oxygen packed products require separately evidenced state/process extensions; a CPC leaf is not proof of such coverage.	ctsg-kelp-nursery-2014; ctsg-seaweed-food-hazards-2020
b_assets	capital_and_auxiliaries	Collect every installed asset and its supplier production, installation, service life, replacement and end treatment under the same scope; no unsupported capital cutoff. Article mass is assigned by justified service use before normalization and is excluded from biological mass inputs. The listed asset configuration is a transparent technical collection design, not a claimed single documented factory bill. Add each actual cable, fitting, building component or other real input as its own specific exchange when outside an already purchased whole article.
b_gate	first_release_and_service	Q is the first food-quality release of new compliant net wet tissue for a defined cohort; delivery, storage transfer, reinspection or rework never creates second production. Same-cohort released closing FG is already part of Q. Keep manufacture, pending-release WIP and released FG/service physical gates separately; paired internal transfers cancel in consolidation. Packaging, storage, handling and dispatch services after release remain separate cohort service accounts, with historical FG burdens retained for the cohort served. Never add historical production to current Q.
b_atomic	all_exchanges	Every real purchased preparation crosses once at whole as-supplied mass; active ingredients, dry solids, carrier water and assay are constituent subledgers. Internally prepared formulations require separate actual purchased materials, water, energy and losses. Record every real emission species and actual receiving compartment or treatment. No other, utility, packaging or pollutant aggregate can hide unlisted exchanges; add conditional specific rows before calculating. No steam, boiler or external hot-water return is presumed by this electrical nursery/cold-chain configuration; if one actually exists record supply/return mass, temperature, enthalpy and supplier water/energy agreement as separate exchanges.

All cards below have final per-reference-flow basis. Their descriptions and cp_<row_id> protocols require distinct raw exchange records; no numeric range is implied by omission. For each non-reference card the one §8 normalize_once result is consumed; the amount expression is a final quantity description, not a second computation. References to context sources explain route/collection needs, never measured exchange amounts.

Inputs

Product flows

Algae (`sorus`)

Authorized fresh Saccharina latissima reproductive sorus only; weigh received net wet tissue and independently measure dry matter. Record source location and collection vessel burden. This generic identity has no species, food grade, moisture, origin or route guarantee; its wild/unfit CPC label conflicts with this use while its full physical description has no matching restriction. It is used solely as generic algal biomass, never as an accepted classification mapping or food approval. Do not substitute other taxa or dried Laminaria. Contrary native metadata explicitly says wild and unfit for human consumption; native owner intent is unknown. This is a conditional generic physical identity, not proof of misclassification or an exact food/farmed/fresh/species match. Independently establish this PCR reference object and delivered quality; never auto-select a wild or nonfood upstream dataset/provider. No reliable generic numerical range is established for this exchange. Collect its undivided actual amount and uncertainty with cp_sorus.

Inputs

Product flows

Algae (`harvest_in`)

Receive the exact fresh Saccharina latissima harvest transfer with all inherited burdens and water/salt subledgers. Generic biomass identity only; wild/unfit classification conflict is disclosed and gives no food approval. Contrary native metadata explicitly says wild and unfit for human consumption; native owner intent is unknown. This is a conditional generic physical identity, not proof of misclassification or an exact food/farmed/fresh/species match. Independently establish this PCR reference object and delivered quality; never auto-select a wild or nonfood upstream dataset/provider. No reliable generic numerical range is established for this exchange. Collect its undivided actual amount and uncertainty with cp_harvest_in.

Outputs

Product flows

Algae (`released_kelp`)

The one reference output is fresh raw whole farmed Saccharina latissima, after harvest, drainage, cooling, identity and food-suitability checks and the FIRST documented quality release. Generic Algae has no species, food grade, moisture, route or geography guarantee; its only wild/unfit CPC classification conflicts with this declared food/farmed use. Physical text and mass property remain compatible; keep all these restrictions with this row, and use no dried Laminaria substitute. Q is newly released net wet tissue excluding free/attached seawater, ice, packaging, rope and fouling taxa under the declared drain protocol; salt and independent dry matter are reported. Q includes same-cohort released closing finished goods, so never add closing FG to production again. Contrary native metadata explicitly says wild and unfit for human consumption; native owner intent is unknown. This is a conditional generic physical identity, not proof of misclassification or an exact food/farmed/fresh/species match. Independently establish this PCR reference object and delivered quality; never auto-select a wild or nonfood upstream dataset/provider.

This index comes from verified structured.yaml and retains the canonical English rule text.

System boundary rules · 5

Rule ID	Applies to	Rule	Source IDs
`b_complete`	cultivation_to_release	Include authorized sorus collection and nursery water treatment, enrichment, spore inoculation, lit/chilled/aerated nursery, seeded twine transport, installation, deployment, monitoring, thinning if actually needed, maintenance, retrieval, harvest, cooling, sampling, inspection, packaging and first food-quality release. Purchased seed does not erase its nursery chain: obtain complete supplier foreground/upstream inventory or explicitly retain the missing upstream burden. This route cannot begin at bought edible kelp.	ctsg-kelp-nursery-2014, ctsg-seaweed-food-hazards-2020
`b_scope`	fresh_food_route	Only cultivated S. latissima raw whole blades under documented food suitability are included. Wild-harvest food, S. japonica, Laminaria digitata, Gracilaria, microalgae, feed/fertilizer/bioremediation biomass, extracts and mixed taxa are excluded. Frozen, dried, ground, washed/blanched or reduced-oxygen packed products require separately evidenced state/process extensions; a CPC leaf is not proof of such coverage.	ctsg-kelp-nursery-2014, ctsg-seaweed-food-hazards-2020
`b_assets`	capital_and_auxiliaries	Collect every installed asset and its supplier production, installation, service life, replacement and end treatment under the same scope; no unsupported capital cutoff. Article mass is assigned by justified service use before normalization and is excluded from biological mass inputs. The listed asset configuration is a transparent technical collection design, not a claimed single documented factory bill. Add each actual cable, fitting, building component or other real input as its own specific exchange when outside an already purchased whole article.
`b_gate`	first_release_and_service	Q is the first food-quality release of new compliant net wet tissue for a defined cohort; delivery, storage transfer, reinspection or rework never creates second production. Same-cohort released closing FG is already part of Q. Keep manufacture, pending-release WIP and released FG/service physical gates separately; paired internal transfers cancel in consolidation. Packaging, storage, handling and dispatch services after release remain separate cohort service accounts, with historical FG burdens retained for the cohort served. Never add historical production to current Q.
`b_atomic`	all_exchanges	Every real purchased preparation crosses once at whole as-supplied mass; active ingredients, dry solids, carrier water and assay are constituent subledgers. Internally prepared formulations require separate actual purchased materials, water, energy and losses. Record every real emission species and actual receiving compartment or treatment. No other, utility, packaging or pollutant aggregate can hide unlisted exchanges; add conditional specific rows before calculating. No steam, boiler or external hot-water return is presumed by this electrical nursery/cold-chain configuration; if one actually exists record supply/return mass, temperature, enthalpy and supplier water/energy agreement as separate exchanges.

Allocation rules · 7

Rule ID	Applies to	Rule	Source IDs
`allocation_rule_1`	foreground_burden_allocation	The conditions in a_scope govern every rule in this section; the residual rule is conditional on the preceding steps.
`a_scope`	attributional_model	Apply this hierarchy only to a declared attributional partitioning case: Situation C2 or another ILCD situation where its goal-specific provisions establish allocation after subdivision, virtual subdivision and relevant substitution/system expansion have been assessed as unavailable or infeasible. Document the chosen decision context; no free choice of allocation versus substitution is implied.	jrc-ilcd-allocation-2010
`a_dedicated`	exchange_attribution	First separate independently metered nursery batches, dedicated gear, trips, cooling and release activities. Use virtual subdivision for materials embodied solely in one output. Failed culture, rejected food and abnormal/idle/cleanup activity remain burdens of their actual crop/function; do not allocate them away by assuming saleable output.	jrc-ilcd-allocation-2010
`a_physical`	remaining_joint_exchanges	For each genuinely remaining shared exchange identify and demonstrate its determining physical causal relation to each function. Gear occupation time, trip payload and refrigeration load are candidates only when actual measurements demonstrate causality for that exchange. Nutrient content or wet/dry mass is not automatically a driver of boat fuel, capital or all emissions. Reconcile allocated vectors to the original vector without changing physical output masses.	jrc-ilcd-allocation-2010
`a_residual`	residual_joint_exchanges	Only when a determining physical causality remains unavailable after the preceding steps use contemporaneous representative market value at the SAME joint-process exit and actual condition/quantity. Derive gate-equivalent values by removing downstream conditioning, packaging, storage and transport costs. Retain prices, dates, quantities, currency, sensitivity and the reason for this residual criterion. No fixed split or automatic choice of economic/physical allocation is provided.	jrc-ilcd-allocation-2010
`a_noncredits`	biomass_and_residues	Rejected tissue, rope waste, meltwater and measured C/N/P uptake are not automatic saleable co-functions or credits. Keep their actual fates and treatment burdens. Photosynthetic uptake is a physical exchange, not permanent carbon storage or avoided nutrient production. No substitution, negative carbon burden or nutrient-removal credit is authorized by this food-crop inventory. An actual additional marketed function needs separate evidence and goal-consistent treatment.
`asset_manufacture_conservation`	existing capital/reusable manufacture attribution	Within the applicable allocation decision context, original manufacture burden attributed across uses of actual capital equipment or reusable articles already included in foreground production, packaging or observed services uses one persistent same-asset ledger across all crops, products, cohorts, manufacturing/postrelease services, owners and observation periods. D is its supported whole installed service: all realized historical service plus supported remaining service in the same units as actual beneficiary use u; D must be finite and positive. Period capacity, remaining-only capacity, the physical asset/article mass alone, or current-period product Q alone is not D; supported whole-service throughput in mass units may be used when it demonstrates the causal service and matches u. This does not amortize the manufactured reference product over downstream life or change its declared reference gate/Q. The fractions u/D and all previously assigned manufacture shares together must never exceed 1. Changes of window, custody, provider or repair never restart the original manufacture balance. Replacements have distinct identities and only their real new manufacture vectors; actual repair and treatment increments remain separately accounted. Revised capacity evidence requires transparent reconciliation of prior shares and sensitivity, not a fresh ledger. Keep full physical mass and stock movements independent of burden shares. Unknown D, prior shares or beneficiary coverage requires review and no final manufacture-attributed amount; no assumed lifetime, utilization, zero or arbitrary division is permitted. For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

Validation rules · 9

Rule ID	Applies to	Rule	Source IDs
`validation_rule_1`	foreground_dataset_conformance	These requirements apply to the whole declared cohort and its actual conditional exchanges, including Q = 0. Engineering inspection can verify declared structure and consistency only; missing measurements or food-suitability decisions cannot be reported as scientifically verified.
`v_identity`	all_rows	Confirm S. latissima, farmed route, fresh raw state and all qualifiers. A generic Algae UUID does not establish food suitability, farmed provenance or an accepted CPC mapping. Reject dried/pressed Laminaria identity for this wet crop; retain every UUID restriction and unresolved auxiliary identity in consumable context.
`v_food`	released_kelp	Before Q require documented current-site food-suitability decision, authorized harvest waters and seed provenance, microbial/chemical sampling with methods/limits, contaminant and iodine risk assessment, sanitation, cold chain and fouling-allergen communication. For the Connecticut reference configuration the 2020 guide specifies cooling within two hours of harvest start and refrigeration set below 41 F (5 C); verify the current applicable authority and operational controls rather than treating this historical guide as current legal clearance. It does not validate shelf life, a pathogen kill step or food-safety certification. Frozen/dried/reduced-oxygen routes have different hazards and cannot inherit this release.	ctsg-seaweed-food-hazards-2020
`v_mass`	physical_gates	Reconcile each nursery, grow-out, release and service physical gate, then the consolidated gate: opening stock + actual external inputs + biological net additions = closing stock + all actual outputs/losses. Preserve dry biomass, salt, intrinsic water, attached seawater, ice and each packaging material separately; reactions/respiration and actual dissolved/gas species need independent evidence. Do not adjust moisture or one unknown flux to close two unknowns. No universal residual tolerance is supplied: use measured uncertainty and investigate imbalance.
`v_elements`	growout	Use independent dry matter and measured C/N/P composition for every biomass stock and destination and independently determined environmental species fluxes. Conserve carbon, nitrogen and phosphorus across uptake, released/standing biomass, losses, respiration and actual discharges. Convert element mass to a chemical species only with measured speciation, correct stoichiometry and charge. Indicators DIC, COD, total N/P and VOC do not identify molecules. No unsupported carbon credit or persistent storage claim.
`v_period`	campaign_and_stock	Include failed/zero-output cycles, startup, shutdown, idle, cleanup, sampling, rework and returns. For each exchange retain opening/closing WIP quantity, stage and inherited burden vector. Reverse the original transfer on returns; assign only incremental rework once. Do not renormalize already normalized historical burdens. Released FG stock cannot create a second Q on inspection or delivery.
`v_packaging`	tote_liner_label	For each distinct packaging component reconcile opening empty + opening attached WIP/FG + opening reusable stock + purchases + external returns received = closing counterparts + material on GROSS physical dispatch + external returns sent + waste. Eliminate internal reuse and transfers only on consolidation. Returned full packs retain their actual contents and historical burden; split empties. Packaging and ice never enter net tissue Q and reuse never implies repurchase or automatic co-product.
`v_calc`	all_inventory_rows	Convert raw units and allocate attributable raw exchange numerators first; apply the single normalization calculation once for Q greater than zero. Cards and protocol aggregation refer to that same result and must not divide it again. Q equal to zero retains absolute activity and inherited burdens and produces no per-unit result. Missing raw data, biological species fluxes or safety decisions remain explicit unavailable findings, not zero or an asserted pass.
`validate_asset_manufacture_conservation`	existing capital/reusable manufacture attribution	For every included capital/reusable manufacture attribution verify same-asset continuity, whole installed service in matched units, all historical/current beneficiaries, prior assigned manufacture shares and cumulative share <= 1. Reject a reset by period, cohort, provider, owner or repair. Check distinct real replacement and incremental repair/treatment vectors separately and preserve gross physical mass. A missing denominator, unexplained previous allocation or incomplete beneficiary ledger requires explicit review and an unavailable final attributed amount; structural inspection cannot claim empirical completeness.
