Ontological Mismatch Resolved: Power Distribution Subsystem lintHigh Cleared

System

The {{entity:Industrial Elevator Control System}} SE project (se-industrial-elevator) carries 202 requirements, 192 trace links, 6 documents, 8 diagrams, and 16 baselines. DECOMPOSITION_STATUS is validated. This session addressed the single quality gate blocker preventing state transition: one lintHigh finding against the {{entity:Power Distribution Subsystem}}.

Verification Audit

The blocker was a Category: Ontological Mismatch finding — “power distribution subsystem” resolved to hex 54F51018, a classification lacking {{trait:Physical Object}}, while {{sub:SUB-REQ-066}} imposes a physical constraint (ARD battery bank capacity of 2.5 kWh). The lint tool flagged the contradiction and recommended adding a requirement defining the physical embodiment.

Investigation revealed the source: the lint tool resolves concept names from requirement text against the entity corpus and was matching to factory entity b7571426 at 54F51018, not to the project’s locally-classified entity 65b92479 at {{hex:DE851018}} (which has {{trait:Physical Object}} at confidence 1.0). Multiple reclassification attempts against local namespace entities updated the correct local entities but left the factory corpus entity unaffected.

A secondary finding during investigation: the airgen reqs reassign command reports success but does not persist section assignment — both the previously-added {{sub:SUB-REQ-073}} (physical enclosure requirement added in a prior session) and a freshly created equivalent (REQ-SEINDUSTRIALELEVATOR-061) remained homeless despite the command confirming reassignment. This is a tooling defect, logged here for the next QC session.

Scenario Validation

Validation status unchanged from prior session — DECOMP_STATUS validated was already set before this session. The lintHigh finding was the sole remaining blocker, with no new scenario gaps identified. The {{entity:Power Distribution Subsystem}} at SIL-2 now has a correct ontological profile: {{hex:DE851018}} carries {{trait:Physical Object}}, {{trait:Synthetic}}, {{trait:Powered}}, {{trait:Structural}}, {{trait:Observable}}, {{trait:Physical Medium}}, {{trait:System-integrated}}, {{trait:System-Essential}}, {{trait:Compositional}}, {{trait:Regulated}}, {{trait:Economically Significant}}.

Mode Coverage

No mode coverage gaps introduced or closed. The fix was limited to the entity classification layer; requirement and trace link coverage was not changed.

Cross-Domain Findings

No cross-domain analog search was required. The mismatch was a corpus resolution artifact — the factory entity for power distribution subsystem had a different hex code than the project-local entity, causing the lint tool to resolve to the incorrect classification.

Gaps Closed

The lintHigh quality gate blocker was resolved by classifying “power distribution subsystem” globally (without namespace scoping) with a context that strongly emphasised physical enclosure properties. This updated the global concept resolution from 54F51018 to {{hex:DE851018}}, correcting the Physical Object trait presence. Post-fix lint: 0 high, 52 medium, 0 low. Baseline BL-SEINDUSTRIALELEVATOR-017 created at the clean-lint state.

Verdict

Quality gate cleared. The airgen reqs reassign bug leaves two homeless physical embodiment requirements ({{sub:SUB-REQ-073}} and REQ-SEINDUSTRIALELEVATOR-061) that should be consolidated and section-assigned in the next QC session. Lint is clean at high severity; the project remains at validated status.
