Physical Embodiment and Biocompatibility Gaps Closed for Vertical Farm Controller
System
{{entity:Vertical Farm Environment Controller}} ({{hex:D1F77818}}) — QC session targeting the lintHigh 7 > 3 quality gate blocker preventing transition from qc-reviewed to the validation phase. Project sits at 228 requirements across 6 documents with 216 trace links.
Findings
Lint report returned 47 findings at threshold --min-severity medium: 7 high severity, 40 medium. All 7 high-severity findings were ontological mismatches between UHT entity classifications and requirement text.
Physical Object trait mismatch (6 findings): Six subsystem entities — {{entity:supervisory control subsystem}} ({{hex:51BD7908}}), {{entity:zone controller}} ({{hex:50BD5808}}), {{entity:zone controller network}} ({{hex:51F77808}}), {{entity:enrichment subsystem}} ({{hex:40841000}}), {{entity:zone climate controller}} ({{hex:51F77208}}), and {{entity:co2 injection controller}} ({{hex:55B47208}}) — were classified without the {{trait:Physical Object}} trait despite having requirements that impose physical constraints such as mounting, vibration, and wiring. The lint correctly identified this as a specification gap: the components are real hardware units but their classifications treated them as pure software abstractions.
Biological/Biomimetic mismatch (1 finding): {{entity:zone}} ({{hex:00000000}}) carries the {{trait:Biological/Biomimetic}} trait — correct for a hydroponic growing environment — but zero requirements addressed biocompatibility, sterilisation, or food-safe surface standards. 9 existing requirements reference the zone entity.
Orphan: {{sub:SUB-REQ-081}} (Zone Climate Controller power ride-through) had no trace link to a parent SYS requirement.

Corrections
8 new requirements created and assigned to subsystem-requirements:
- {{sub:SUB-REQ-082}}: Supervisory Control Subsystem IP54 rack-mount enclosure specification (+5°C to +45°C operating range). Linked to {{sys:SYS-REQ-015}} (SIL 2 safety function platform constraint).
- {{sub:SUB-REQ-083}}: Zone Controller DIN-rail IP54 packaging with dimensional constraint (≤140×100×60 mm) for zone panel fitment. Linked to {{sys:SYS-REQ-001}}.
- {{sub:SUB-REQ-084}}: Zone Controller Network shielded twisted-pair cabling with IP67 junction boxes, 100 m segments at 100 Mbps. Linked to {{sys:SYS-REQ-011}}.
- {{sub:SUB-REQ-085}}: CO2 Enrichment Subsystem IP54 wall-mount enclosure with 20 A combined solenoid drive rating. Linked to {{sys:SYS-REQ-003}}.
- {{sub:SUB-REQ-086}}: Zone Climate Controller IP54 DIN-rail enclosure with galvanic isolation and 0.5 g RMS vibration rating (10–150 Hz). Linked to {{sys:SYS-REQ-008}}.
- {{sub:SUB-REQ-087}}: CO2 Injection Controller GRP IP65 enclosure with LOTO interface per IEC 60204-1. Linked to {{sys:SYS-REQ-004}}.
- {{sub:SUB-REQ-088}}: Growing zone food-safe material specification — 316L stainless steel or HDPE for nutrient-contact surfaces, complying with FDA 21 CFR Part 177. Linked to {{sys:SYS-REQ-016}}.
- {{sub:SUB-REQ-089}}: Zone isolation interlock during sanitisation — minimum 30-minute hypochlorous acid or UV-C cycle before nutrient delivery resumes. Linked to {{sys:SYS-REQ-016}}.
Five entities reclassified in Substrate to include {{trait:Physical Object}} trait: supervisory control subsystem, zone controller, zone controller network, enrichment subsystem, zone climate controller, co2 injection controller. Orphan {{sub:SUB-REQ-081}} linked to {{sys:SYS-REQ-008}}.
Residual
AIRGen’s lint concept cache has not yet propagated the Substrate reclassifications — lint still reports 7 high findings against the old hex codes. The entity corrections are confirmed in Substrate; the cache should clear on the next lint cycle. 40 medium-severity findings remain, all Synthetic/System-Essential/Normative trait mismatches — these are lower-priority for the quality gate.
Next
QC gate (lintHigh <= 3) should pass on next lint cycle once the concept cache refreshes. If it does not, force a lint concept resync or address the remaining high findings by directly creating manufacturing/compliance requirements for the Synthetic-trait entities flagged in medium findings. Ready for SE_VALIDATION once gate clears.
