# Rock lobster and other sea crawfish, frozen, dried, salted or in brine

## 1. Scope and Applicability

This PCR supports foreground data packages for rock lobster and other sea crawfish preserved and marketed as frozen, dried, dry-salted, or in brine. The producer shall declare exactly one preservation route for each reported result. Route-specific inputs, yields, wastes, storage conditions, and results shall remain separate; a multi-route average is allowed only when each route result and the aggregation basis are also disclosed.

The foreground boundary begins with received live, fresh, chilled, or otherwise declared source crustaceans at the processing gate and ends with 1 kg net preserved product at the producer gate after packaging and, for the frozen route, frozen storage to the declared dispatch point. Harvesting or aquaculture, feed, vessel operations, and inbound transport are represented by upstream datasets. Distribution after the producer gate, retail, consumer preparation, and end-of-life are excluded unless separately added by the study.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `allocation_subdivide_routes` | frozen, dried, dry-salted, and brined production | Subdivide route-specific processes, utilities, yields, and wastes before allocation. Report each route result separately and do not use an unconditional multi-route average. | `eu-pef-2021-2279` |
| `allocation_shared_operations` | shared preparation, packaging, and site utilities | Use direct measurement first; otherwise use a documented physical causal driver such as processed mass, metered operating time, or capacity-time. If no physical relationship can be justified, use a documented economic allocation with contemporaneous prices and a sensitivity result. | `eu-pef-2021-2279` |
| `allocation_residues_and_coproducts` | shell, viscera, rejects, recovered product, and other outputs | Classify each output as product, co-product, or waste using its actual destination. Avoid allocation by process subdivision; when unavoidable, apply the same physical-then-economic hierarchy and disclose any credits or substituted products separately. | `eu-pef-2021-2279` |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `dq_identity_and_route` | every dataset | Declare species or commercial group, presentation, shell/cooking status, exactly one preservation route, net-mass method, packaging, and gate condition. | product specification; batch record; label; route code |
| `dq_temporal_and_site_coverage` | foreground records | Use a representative period covering all included lots, routes, shifts, and seasonal conditions; disclose exclusions, shutdowns, and shared-service allocation. | production calendar; lot list; meter coverage; exclusion log |
| `dq_measurement_and_reconciliation` | mass, water, energy, salt, packaging, waste, and refrigerant | Retain calibration or invoice evidence, reconcile process balances, and investigate missing records, outliers, and unexplained losses before aggregation. | calibration certificates; invoices; balance worksheets; corrective-action records |
| `dq_upstream_and_proxy_quality` | upstream datasets | Assess technological, geographical, temporal, and precision/completeness suitability; disclose proxy choices and material mismatches. | dataset metadata and documented data-quality rating consistent with `eu-pef-2021-2279` |
| `dq_reasoned_estimates` | all provisional ranges | Do not use these QA ranges as measured foreground values. Replace each with collected or accepted source-backed evidence, or document reviewer acceptance and uncertainty before activation. | review record; replacement source or approved uncertainty note |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `validate_reference_flow` | reference flow and packaged output | Verify one reference flow equals exactly 1 kg net target product using the declared drainage, glaze, packaging, and shell basis and the specified Mass property and unit group UUIDs. | `codex-cxc-52-2003` |
| `validate_single_route` | process map and inventory | Verify exactly one of `frozen`, `dried`, `dry_salted`, or `brined` is declared for each result; frozen storage shall appear only for `frozen`, while salt and brine inputs shall appear only when used by the declared route. | `codex-cxc-52-2003`; `unsd-cpc-3-0-2025` |
| `validate_mass_and_utility_completeness` | foreground inventory | Verify process mass reconciliation and coverage of material water or ice, electricity, thermal energy, salt, packaging, residues, wastewater or spent brine, and refrigerant flows applicable to the route; require a documented zero or exclusion for any applicable missing flow. | `eu-pef-2021-2279` |
| `validate_food_safety_traceability` | lot and route records | Verify traceable lots and applicable time-temperature, hygiene, drying, salting/brining, and release-control records are retained; failure is a data-quality finding and this PCR does not certify legal compliance. | `codex-cxc-52-2003` |
| `validate_provisional_ranges` | reasoned-estimate QA guardrails | Flag values outside a provisional range for investigation, but never replace foreground records with the range; all provisional ranges remain review items before activation. |  |
| `validate_uuid_completeness` | non-reference inventory flows | Before activation, resolve and review Tiangong UUIDs for material non-reference flows or document an approved semantic fallback; the reference flow UUID is mandatory. |  |
