# Raw hides and skins of goats or kids

## 1. Scope and Applicability

This rule covers separately recovered, fresh or first-stage preserved, untanned goat and kid raw skins. It applies to slaughter and lawful, quality-acceptable fallen-animal recovery. It does not treat a skin retained on a carcass as a separate product. Declare species, provenance, state, grade, actual removal/recovery/curing gate and reporting period. Exclude sheep skins, furrier-class raw furskins, detached hair, chromium-tanned wet blue, other leather and post-gate transport. Upstream goat husbandry may serve meat, milk, fibre or breeding across periods; its burdens must be linked, never silently discarded.

## 2. Product Category Identity

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | One separately marketed raw goat or kid skin lot at its actual handover |
| How much | 1 kg net as-sold skin; exclude detachable packaging and free brine |
| How well | goat/kid species, legal source, route, grade, fresh/chilled/dried/salted/brined state, moisture and retained salt |
| How long or cycle | measured terminal-event-to-handover lot, linked to actual animal-production and shared-service periods |
| reference_flow_link | `raw_goat_skin` |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Raw goat or kid skin at actual handover |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | goat or kid; actual recovery; legal source; grade; fresh/preserved route; moisture; retained salt; net package exclusion; gate; animal and facility periods |

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `net_sale_mass` | reference and marketable intermediate skins | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Weigh net skin at each actual state and gate; exclude removable package and free brine. |
| `state_mass` | fresh to preserved comparison | Mass | kg | Measure before/after skin mass, water loss and retained salt; never apply a universal fresh-to-cured factor. |
| `period_meter` | shared energy and upstream animal service | Energy and time | kWh, h | Keep carrier meters and service hours by actual reporting period before per-kg normalization. |
| `inventory_reference_normalization` | all inventory rows | Actual flow property | exchange unit per reference flow | The inventory and collection aggregation fields below express final amounts per declared reference flow. Keep all raw collection records, original denominator qualifiers, route/period strata, unit conversions and allocation requirements. For each flow, first obtain its attributable amount in its own numerator unit using the existing rules; then divide by the measured accepted reference-output quantity of the same scope and multiply by the declared reference quantity. Do not mix species, states, gates or incompatible routes; count transfers and shared burdens once. A missing, zero or untraceable accepted-output denominator is a blocking data-quality issue. Keep provisional QA ranges on their explicitly stated bases; they are not conversion factors or production defaults. Compute normalized amount = attributable amount * declared reference quantity / measured accepted reference-output quantity. Apply normalization once only; never divide an already normalized value again. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Identified live goat/kid delivered for slaughter, or legally recoverable fallen body; link the route-compatible animal-production dataset without duplicating its exchanges. |
| starting_condition_role | Product for live slaughter; Waste for fallen body only where that is its actual legal flow role. Product-status fallen recovery requires a separately verified Product exchange. |
| product_classification_scope | CPC 3.0 `02954` raw goat/kid skin, not CPC furskin or processed leather. |
| recursive_input_rule | Purchased same-category raw skin entering conditioning carries its own upstream dataset; do not treat it as newly removed skin or reallocate the originating animal. |
| upstream_dataset_requirement | Species, meat/milk/fibre/breeding history and periods, terminal route, real co-products, salt, utility and package datasets compatible with actual state and gate. |
| disclosure | animal ID/lot, upstream boundary, legal recovery, skin removal, output set, allocation, periods, shared assets, grade, state and handover. |

### Boundary Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `animal_link` | upstream and terminal | Husbandry remains in a route-compatible upstream dataset, including meat/milk/fibre/breeding history. If upstream already includes slaughter, do not repeat its burden in the foreground terminal node; record a handover ledger instead. | `fao-small-ruminant` |
| `independent_skin` | terminal removal | Flaying or lawful recovery is distinct from husbandry and first conditioning. Only an actually separated marketable skin enters this PCR; skin-on carcass does not create an invented hide. | `fao-small-ruminant` |
| `actual_gate` | all routes | Stop at actual removal, slaughterhouse, lawful recovery or curing handover before tanning; exclude later distribution and leather manufacture. Omit unperformed downstream nodes for an early fresh-skin gate. | `un-cpc-3`; `fao-hides` |
| `state_destinations` | conditioning to presentation | Identify wet/prepared, accepted/downgraded/rejected and fresh/preserved states and their handoffs. Fresh skin bypasses preservation; package protects but does not add net skin mass. | `fao-hides`; `fao-small-ruminant` |
| `shared_asset_scope` | removal, conditioning, grading, preservation, presentation | Identify shared rooms, meters, curing frames and reusable containers; enumerate consuming nodes and periods, then attribute each burden once. | `fao-hides` |

| `preservation` | Conditional raw-skin preservation | conditional | actual preservation only | Treat only actual chilling, drying, salting or brining; fresh sale bypasses. | measured lot |
| `gate` | Protective presentation and actual handover | required | recorded route | Protect and transfer one raw skin product at the declared gate. | measured lot |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `animal_phase` | meat/milk/fibre/breeding history | Link upstream inputs, animal services, replacement and termination to actual periods and products. Apply documented physical causality where defensible; otherwise use disclosed economic relation with sensitivity. Do not assign zero or all lifetime burden to the hide by default. | `fao-small-ruminant` |
| `terminal_output_set` | slaughter versus fallen recovery | List every actual independently marketed skin, meat/carcass and other terminal output and its handover; allocate joint burdens only among real intended products, with shares summing to one. Fallen recovery creates no assumed meat product. Residue and Waste are not automatically co-products. | `fao-small-ruminant` |
| `grade_and_state` | sorting and preservation | Saleable accepted and downgraded grades are distinct products only where actual independent sales occur; rejected skin, spent brine and trims follow measured treatment. Do not credit loss as saleable output. | `fao-hides` |
| `shared_period` | shared sites and containers | Allocate room, frame, meter and reusable-container burdens among actual consuming nodes/lots and periods by measured hours or throughput; count each service once and disclose choice. | `fao-hides` |

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 |
| --- | --- | --- |
| `preservative_specific_input` | `cp_preservation` | Operation preservation: Actually used salt, brine constituent or other permitted medium. Denominator and scope requirements：per actual recorded lot; final result normalized to 1 kg net as-sold raw skin Original quantity method: Identify substance and measure input; no universal salt dose or fixed flow identity. |
| `protective_material_specific_input` | `cp_gate` | Operation gate: Actually used reusable or single-use protective packaging. Denominator and scope requirements：per actual recorded lot; final result normalized to 1 kg net as-sold raw skin Original quantity method: Record material and reuse count; package mass is excluded from net skin reference. |


### Data Collection Protocols

| protocol_id | process_id | flow_role | record_type | raw_fields | collection_method | unit | frequency | temporal_coverage | site_scope | aggregation_rule | quality_evidence |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| `cp_removal` | `removal` | actual terminal event and independent skin | animal-event ticket | animal and lot ID, species, source route, legal status, live/body mass, skin removal, skin/meat/other products, Waste, gate, period |slaughter/recovery tickets, calibrated scales, upstream dataset linkage; Raw aggregation requirements: match one body input to real outputs and recorded loss. Apply the existing route, period, conversion and allocation rules; retain raw totals and the measured accepted reference-output denominator for the same scope. Perform final normalization exactly once; do not divide an already normalized amount again. other_terminal_specific_output: Mandatory product output identification, not a selected exchange. Preserved collection scope: Other actually marketed terminal products, if any. Denominator and scope requirements：per actual recorded lot; final result normalized to 1 kg net as-sold raw skin Preserve each actual product output separately, including its actual material/species, physical state, native property/unit, measured quantity, period, destination and unique handover. Before dataset completeness, instantiate a physically specific exchange per actual identity and confirm a compatible UUID or retain its exact unresolved identity. Keep original throughput/normalization, allocation and reuse/stock obligations. A material/function class is not one exchange; do not copy the retired class-level range to components, invent a recipe or infer zero from missing records. Do not duplicate actual quantities or products already represented by another card. | kg, event | each event | animal service and terminal periods | actual source and removal site | per reference flow | tickets, scales, legal records; traceable numerator, accepted reference-output denominator and normalization worksheet |
| `cp_conditioning` | `conditioning` | first prepared-skin state | processing batch | incoming skin, water, prepared skin, trims, moisture, lot, time | batch sheet, water meter and calibrated scale; Raw aggregation requirements: reconcile mass by state and treatment. Apply the existing route, period, conversion and allocation rules; retain raw totals and the measured accepted reference-output denominator for the same scope. Perform final normalization exactly once; do not divide an already normalized amount again. | kg, h | each batch | reference production period | actual conditioning site | per reference flow | meter and scale calibration; traceable numerator, accepted reference-output denominator and normalization worksheet |
| `cp_grading` | `grading` | accepted/downgraded/rejected destinations | grade ledger | incoming lot, grade, accepted, downgraded, rejected masses and destinations | scale and sale/dispatch documents; Raw aggregation requirements: partition actual grade and reject destinations. Apply the existing route, period, conversion and allocation rules; retain raw totals and the measured accepted reference-output denominator for the same scope. Perform final normalization exactly once; do not divide an already normalized amount again. | kg | each lot | reference production period | grading site | per reference flow | grade and dispatch evidence; traceable numerator, accepted reference-output denominator and normalization worksheet |
| `cp_preservation` | `preservation` | actual curing or chilling | preservation batch | inlet state and mass, salt/medium, utility carrier, output state/mass, moisture, retained salt, spent liquor, time | batch sheet, meter and laboratory/scale records; Raw aggregation requirements: separate fresh bypass and each intervention. Apply the existing route, period, conversion and allocation rules; retain raw totals and the measured accepted reference-output denominator for the same scope. Perform final normalization exactly once; do not divide an already normalized amount again. `preservative_specific_input`: Operation preservation: Actually used salt, brine constituent or other permitted medium. Denominator and scope requirements：per actual recorded lot; final result normalized to 1 kg net as-sold raw skin Original quantity method: Identify substance and measure input; no universal salt dose or fixed flow identity. 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. `preservation_waste_specific_output`: Spent brine, rejected skin and other actual preservation residues. Denominator and scope requirements：per actual recorded lot; final result normalized to 1 kg net as-sold raw skin Separate liquid and solid treatment and record mass without hiding moisture loss. This is a mandatory specific-output collection requirement, not a selected exchange. Preserve every actual waste, residue, reject and co-product from this operation. Create separate cards for physically distinct streams with actual material, composition/state, quantity, receiving route and Product/Waste role before dataset completeness; verify a compatible UUID or explicitly retain its unresolved identity. A genuinely mixed stream may remain one physically defined mixture supported by composition records; never invent separation or count its components again. Keep liquid and solid treatment quantities separate. Preserve original period, output balance, reference normalization and allocation rules; missing records do not establish zero or exclusion.  | kg, kWh, h | each preserved batch | actual preservation periods | curing site | per reference flow | batch, calibration and sample record; traceable numerator, accepted reference-output denominator and normalization worksheet |
| `cp_gate` | `gate` | net saleable skin and package | dispatch lot | incoming state, grade, gross mass, free brine, package tare/reuse, net skin mass, gate, destination | dispatch scale, container ledger and invoice; Raw aggregation requirements: one final net-skin output per sold lot. Apply the existing route, period, conversion and allocation rules; retain raw totals and the measured accepted reference-output denominator for the same scope. Perform final normalization exactly once; do not divide an already normalized amount again. `protective_material_specific_input`: Operation gate: Actually used reusable or single-use protective packaging. Denominator and scope requirements：per actual recorded lot; final result normalized to 1 kg net as-sold raw skin Original quantity method: Record material and reuse count; package mass is excluded from net skin reference.

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. | kg, event | each dispatch | reference handover period | actual handover site | per reference flow | dispatch and tare tickets; traceable numerator, accepted reference-output denominator and normalization worksheet |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| `net_reference` | handover | Net skin mass = gross weighed dispatch minus detachable package and free brine; divide attributable inventories by measured net kg. | gross, package tare, free brine, lot ID | inventory per 1 kg as-sold raw skin | `un-cpc-3` |
| `state_balance` | each preparation node | Reconcile state-specific inlet mass plus actual added water/salt with outgoing skin, residues, drained liquor and measured moisture change; no universal conversion. | lot masses, moisture, salt, water, losses | documented state transition | `fao-small-ruminant` |
| `attribution_check` | animal and shared assets | Sum attributable shares to one per real joint-output node and service period; never count same animal phase, room, meter or container twice. | product sales, physical drivers, periods, service records | attributable burden per final kg | `fao-hides` |
| `packaging_reject_identity_and_fate` | `gate` | The packaging_reject collection role is mandatory when the original operation generates these materials. Record the actual material, composition, state, measured mass and destination separately for each physically distinct stream. Dust, chaff, grain, packaging and product rejects must not share one exchange merely because they arise at the same operation. A physically mixed stream may have one card only with its composition and treatment boundary documented. For downgraded produce, distinguish intended saleable co-products supported by recipient and use evidence from actual waste sent to treatment; a lower grade alone does not determine waste status or allocation. Keep on-site rework/internal returns and in-field retained biomass in reconciled internal ledgers instead of exporting them as waste. Create concrete product or waste cards as appropriate before completeness, with a compatible verified UUID or explicit unresolved identity; keep every attributable burden, do not credit unsubstantiated substitution, and do not count any stream twice. Normalize measured quantities once to the original accepted reference output. A missing identity, amount or destination blocks completeness; no aggregate default or numeric bound is inferred. | `cp_gate` | Identity-specific exchanges and reconciled activity records |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `legal_trace` | each recovered skin | Verify goat/kid identity, terminal route, lawful and quality-acceptable recovery, actual separate skin sale and gate. | animal ticket, legal and dispatch record |
| `state_trace` | all mass transitions | Distinguish wet, prepared, graded, fresh and preserved skin; document moisture, retained salt and package tare. | calibrated scales, tests, batch ledger |
| `period_complete` | upstream and shared service | Link meat/milk/fibre/breeding periods, terminal event, assets and every consuming node; record exclusions and branch bypass. | upstream dataset, meter and period ledger |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `category_gate` | reference | Reject sheep, furrier furskin, tanning-stage wet blue or non-raw leather; require species, state and actual pre-tannery gate. | `un-cpc-3` |
| `separation` | terminal | Check a skin is physically recovered and sold separately; no invented output from skin-on carcass. Match live Product or fallen Waste to the actual route and legal role. | `fao-small-ruminant` |
| `route_balance` | all nodes | Match lot IDs and measured masses from removal to final single handover; reconcile accepted, downgraded, rejected, retained salt, free brine and explained moisture change. | `fao-small-ruminant` |
| `outputs_periods` | allocation | Confirm actual meat/milk/fibre/breeding output sets, periods, shared consumers and attribution shares; prevent zero/whole-hide burden defaults and double count. | `fao-hides` |
| `identity_resolution` | concrete dataset exchange | Resolve each unresolved product/waste/elementary identity to a detail-verified compatible flow before generating a final exchange; conditional flow scope is provisional, not a UUID. |  |
| `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. | |
