Sizing evidence report

The Sizing Evidence Report exports the evidence emitted by auto-sizing calculations. It is separate from due diligence reports and focuses on sizing transparency for designers and reviewers.

What the report includes

Each component is shown as a narrative card with:

Historical sizing-result status (PASS, WARN, FAIL, or UNCITED)
Routing and installation assumptions (length, installation type, raceway, ambient, CCC, conductors per run)
Cable construction context (series/type, conductor material, insulation, voltage, termination basis)
Sizing evidence trace (normalized inputs, formulas, recommended value, and acceptance evidence when present)
Constraints such as parallel runs, margins, and ampacity limits
Code book trace (rule references and table lookup strings)
Warnings and errors
Expandable raw trace payload

Citation requirements

Cards are expected to include:

Code book name (for example NEC 2026)
Rule references (for example NEC 430.22)
Table lookup trace (for example NEC 310.16 (Copper, 75C), 250 kcmil -> 255 A)

If citation data is missing, the card is marked UNCITED.

What UNCITED means

UNCITED means the sizing evidence has a selected result but does not include complete standards/table lineage. Treat these cards as requiring manual review before external sign-off.

Scope boundaries

v1 reports route assumptions from current cable metadata fields. It does not claim geometric route pathing (for example turn-by-turn tray/conduit geometry), because that path model is not currently stored.

Historical evidence and current selection

The report keeps the last stored sizing result as historical evidence. It also includes the current selection check when the export has an authenticated sizing context. That check evaluates installed ratings, conductors, parts, modes, and applicable settings from one current project or scenario snapshot.

Manual and locked selections remain checked. A selected value can differ from the historical recommendation and still pass the checked requirements. A failed or unavailable check does not become a current pass because an older sizing result passed; the report shows the unavailable or failed state and retains the historical details separately.

The current check covers its reported requirements and scope. It does not establish whole-project compliance, coordination, fault duty, motor starting, or other analysis that is outside the listed findings.
