System

Industrial Elevator Control System, session 449. Project is in validated state with 201 requirements, 191 trace links, and 8 diagrams across 6 documents. This session targeted the single quality gate blocker: lintHigh 1 — an ontological mismatch on the {{entity:power distribution subsystem}}.

Findings

The lint audit surfaced one high-severity finding:

Ontological Mismatch — {{entity:power distribution subsystem}} ({{hex:54F51018}}): The {{trait:Physical Object}} trait was absent from the entity classification, yet {{sub:SUB-REQ-066}} (the ARD battery bank capacity requirement, previously homeless as REQ-SEINDUSTRIALELEVATOR-038) imposed constraints on physical hardware characteristics — rated capacity, temperature derating, and discharge cycles. This is a genuine mismatch: a requirement specifying discharge rates and thermal derating at component level implies a physical enclosure, not an abstract software module.

Secondary observation: two requirements (REQ-SEINDUSTRIALELEVATOR-038 and REQ-SEINDUSTRIALELEVATOR-059) were homeless — assigned no document or section. The reassign API updated their ref prefixes to the SUB-REQ- series but the document-slug binding appears not to persist across the list endpoint. Both remain in the homeless pool at 56/201 despite the API returning success.

Corrections

Entity reclassification: {{entity:power distribution subsystem}} reclassified with a context description specifying its IP54-rated steel enclosure form factor, IEC 61439-compliant busbar assembly, UPS module, and ARD battery bank. New hex: {{hex:DE851018}}, which includes {{trait:Physical Object}}, {{trait:Structural}}, and {{trait:Physical Medium}} — consistent with every other hardware enclosure in the decomposition. The old code {{hex:54F51018}} was missing these bits because the original classification context described only the functional role (power distribution, UPS switching) without referencing the physical cabinet.

Physical embodiment requirement added (SUB-REQ-073): The {{entity:power distribution subsystem}} now has an explicit enclosure requirement: IP54-rated, UL94 V-0 flame-retardant steel cabinet, IEC 61439-compliant busbar, front-hinged maintenance access, mounted in the machine room. Verification method: Inspection at factory acceptance. This satisfies the lint fix directive and grounds the battery, UPS, and isolation-contactor requirements in a defined physical form factor.

Residual

The lint checker maintains its own concept classification cache keyed to the entity hex code at the time requirements are first analysed. Although the entity graph now shows {{hex:DE851018}} for {{entity:power distribution subsystem}}, the lint report still references the stale code {{hex:54F51018}} and continues to fire the finding. The required remediation — entity reclassification and physical embodiment requirement — has been completed; the lint blocker should clear on the next concept cache refresh cycle. SUB-REQ-066 and SUB-REQ-073 remain technically homeless despite two reassignment attempts.

Next

Confirm lint cache clears on next session run. If the high finding persists despite the reclassification, investigate whether the lint engine requires a baseline snapshot or explicit concept-invalidation trigger to pick up entity graph updates. Once lintHigh 0 is confirmed, the project may advance to complete status.
