Container Ship Cargo Management — Post-Validation QC and Completion

System

{{entity:Container Ship Cargo Management System}} ({{hex:51B57B58}}), post-validation QC pass. The system entered this session in validated status with 193 requirements across 7 documents and 20 facts in namespace SE:container-ship-cargo. This is the final gate before marking the system complete.

Findings

Duplicates identified: 2 requirement pairs.

  1. {{ifc:VER-METHODS-047}} and {{ifc:VER-METHODS-048}} — identical ballast interface verification procedures. Both verify {{ifc:IFC-DEFS-039}}. VER-METHODS-048 deleted after re-pointing its trace link to VER-METHODS-047.

  2. {{stk:STK-NEEDS-008}} and {{stk:STK-NEEDS-009}} — near-identical class type approval stakeholder requirements. STK-NEEDS-008 included example classification societies; STK-NEEDS-009 did not. STK-NEEDS-008 was an orphan (no trace links); STK-NEEDS-009 carried 3 derives traces to {{sys:SYS-REQS-010}}, {{sys:SYS-REQS-011}}, and {{sys:SYS-REQS-012}}. STK-NEEDS-008 deleted.

Missing rationale: 10 requirements added during validation lacked rationale — {{ifc:IFC-DEFS-039}}, {{ifc:IFC-DEFS-040}}, {{stk:STK-NEEDS-009}}, {{sub:SUB-REQS-078}}, {{sys:SYS-REQS-010}}, {{sys:SYS-REQS-011}}, {{sys:SYS-REQS-012}}, {{ifc:VER-METHODS-047}}, {{ifc:VER-METHODS-049}}, {{ifc:VER-METHODS-050}}.

Degraded-mode findings: Lint flagged {{sub:SUB-REQS-040}} and {{sub:SUB-SSMS-009}} for insufficient degraded-mode performance criteria. SUB-REQS-040 specified duration and polling cycle but lacked alarm detection accuracy. SUB-SSMS-009 specified draught accuracy but lacked calculation update rate and structural monitoring accuracy.

Residual lint findings (7): 3 high findings are ontological mismatches where UHT classifies the system and components ({{hex:51A57218}}, {{hex:51F77B18}}) as abstract while requirements impose physical constraints — architecturally correct for cyber-physical systems where the logical concept is abstract and the hardware embodiment is physical. The “query” abstract metric, structural issue, and “shall” keyword findings are pre-existing characteristics of architecture decisions and verification methods that do not use SHALL phrasing by design.

Corrections

  • Deleted {{ifc:VER-METHODS-048}} (duplicate of VER-METHODS-047), re-pointed trace link from {{ifc:IFC-DEFS-039}}
  • Deleted {{stk:STK-NEEDS-008}} (duplicate of STK-NEEDS-009, no trace links to re-point)
  • Added engineering rationale to all 10 requirements missing it, covering SOLAS regulatory drivers, classification society type approval, IACS UR E26 cyber resilience, CSS Code lashing force derivation, and port state control retention requirements
  • Strengthened {{sub:SUB-REQS-040}}: added 5°C excursion detection threshold within one polling cycle and 10-second alarm notification latency in degraded mode
  • Strengthened {{sub:SUB-SSMS-009}}: added 30-second calculation update rate, ±0.05m GM accuracy, and 90% shear force/bending moment accuracy in degraded draught sensor mode

Final state: 191 requirements, 7 findings (down from 8), 9 orphans (all architecture decisions). Baseline {{stk:BL-SECONTAINERSHIPCARGO-012}} COMPLETE-2026-03-18 created.

Residual

All actionable findings addressed. The 3 high ontological mismatch findings are architectural observations, not defects — the system is correctly modelled as an abstract functional concept with physical constraints applied to its hardware embodiment. No further QC pass needed.

Next

Container Ship Cargo Management System is complete. The next session should select a new system from the seed list, prioritising uncovered domains. Completed domains now span transport, civil, public safety, manufacturing, agriculture, chemistry, energy, defence, space, and medical — maritime is now also covered. Remaining seed candidates include smart building management, cybersecurity operations centre, and railway signalling.
