| A/B/D register | The named source-document register that catalogues every cert, plan, and manual a vessel needs. Files are tagged with A-, B-, or D-prefixed slot codes. Of the full register, only 6 docs are blocking for the CL Build (the six-blocker subset). |
| CL | Component List. Per-vessel structured inventory of every UCS-coded component. |
| CL Build | The auto-generated CL skeleton for a vessel, derived from particulars + GA + tanks + Master List. |
| CL Remap | Advisory drafts that propose code reassignments for an existing CL. Supervisor + admin only. |
| DM badge | "Documents Missing" — blue badge on a component card meaning the component is populated but no source document is attached. |
| DWT | Dead-weight tonnage. RAPAX uses Summer Salt Water DWT as the authoritative value, propagated from Particulars on approval. |
| ECDIS | Electronic Chart Display and Information System. One of the 6 mandatory blockers. |
| Form E / Form SER | Equipment / Safety Equipment Record. One of the 6 mandatory blockers. |
| GA Plan | General Arrangement Plan. One of the 6 mandatory blockers. |
| GMDSS Radio Installation Record | One of the 6 mandatory blockers. |
| Group 1 / G1 | Class-and-flag documents (certs). The "Run 1" pipeline populates these. |
| Groups 2–8 | Component groups. The "Run 2" pipeline populates these from particulars + equipment + tanks + Master. |
| Hierarchy Atlas | The L1 / L2 / L3 (Primary / Secondary / Tertiary) grouping that drives navigation, breadcrumbs, and the missing-component picker. |
| IMO number | Vessel's IMO identifier — propagated from Particulars on approval, becomes authoritative. |
| ITCOM | IT / Communications superintendent department. |
| KB / Knowledge Base | cl_knowledge_base — corrective post-AI rewrite layer. Read-only from the LLM. |
| L1 / L2 / L3 / L4 / L5 / L6 | UCS hierarchy levels. L1=Primary Group, L2=Secondary Group, L3=Tertiary Group, L4=family/code, L5=suffix, L6=collapsed-suffix. |
| Master List | The deterministic, code-perfect source-of-truth list of every component code. Lives in ucs_master_list, owned by the administrator. |
| MOC | Management of Change. |
| MSI | Marine Superintendent department — Marine Superintendent, never "Marine Inspector". |
| NCR | Non-Conformity Report. |
| PMS | Planned Maintenance System (the app itself). |
| Particulars | Ship's Particulars PDF. One of the 6 mandatory blockers; IMO + DWT become authoritative on approval. |
| provenance_quality | Tag on extracted fields: `extracted |
| Quarantine | cl_knowledge_base.quarantined=1 for orphan codes (target not in the active Master). Healed by the KB orphan heal job. |
| RAG | Retrieval-Augmented Generation. RAPAX uses dense (Vectorize) + sparse (D1 FTS5) hybrid retrieval. |
| Run 1 | Group-1 cert population pipeline. Reads cert filename prefix → G1 row + cert metadata. |
| Run 2 | Groups 2–8 component population pipeline. CL Skeleton Builder reads particulars + equipment + tanks + Master. |
| Six-blocker subset | The 6 mandatory blocker docs: Particulars, Capacity Plan, GA Plan, Form E/SER, GMDSS, ECDIS. CL Build is gated by these. |
| Source document | Any file uploaded against a vessel — cert, plan, manual, etc. Lives in source_documents. |
| Sister vessel | Detected on dimensions + flag + class — particulars and equipment can be inherited. |
| Supersede | When a new doc replaces an existing one for the same (vessel_id, wizard_slot). The old doc is moved to source_documents_archive with superseded_by_source_document_id. |
| TSI | Technical Superintendent department. |
| UCS | Universal Component Structure. The deterministic taxonomy that codes every component (e.g. 1.0.3.004). |
| UCS Foundation | The active version of the Master List + Hierarchy Atlas + Drawings registry. Owned by the administrator. |
| Wizard slot | A named slot in the Class & Flag Documents wizard that maps to a specific G1 UCS code (e.g. 1.0.3.001 MLC INSURANCE — REPATRIATION). |
| Worker | The single Cloudflare Worker pms-system-builder serving all of pmsplanner.com. |
