The library step runs ONLY when SPEC params are empty and the Family & Type has exactly one library record — ambiguous families never backfill. Greys out loudly if bom_library.json is unavailable.

Unit = boq_data.unit_for(atomic), contract = contract_qty(atomic) — promoted from the contract BOQ. Modeled figure follows the unit: m → Σ CURVE_ELEM_LENGTH (ft→m via icz.units) · St → count · m² → Σ area. A v1 catalogue (no units) renders the classic Count/Length/Area table — columns appear only when the catalogue carries them.

STATION 04 Reconcile NEW station

Audit the model against the firm DX BOM library: FILLED SPEC params that contradict the library record are findings. Read-only — correcting a filled param stays a human decision.

? How the classifier works (the former How-It-Works page, folded into Setup)

0 · Library backfill (r24): empty SPEC_NAME/MATERIAL + uniform Family & Type library record → values filled, element tagged LIB. Filled params are never overwritten; ambiguous families never backfill. 1 · Material: SPEC_MATERIAL_TEXT_EN → segment XX.XX. (exact, then substring). 2 · Fitting: SPEC_NAME_EN → XX.XX.YY. (144 rules); Family & Type fallback + cross-check (61) — name wins, disagreement flags. 3 · Size: SPEC_SIZE / RBS_CALCULATED_SIZE → NW parse → atomic leaf; sized types refuse fallback (loud size-miss). 4 · Bill (r24): unit + contract per atomic from the source BOQ → totals in the code's own unit, Δ against contract.
