System Role

UUID: EA7814F1-819A-4C2F-A709-6B4C829C8EB5

Summary: The Host PC wavelength-mapping system associates each ordered effective detector position and corrected value with wavelength using an approved map and retains coverage and known-reference residual evidence.

System Objectives

UUID: 500B2C55-787B-4AE7-B6B3-6DD20C6360DF

Objective 1: Position mapping. Wavelength Mapping shall use a pixel-to-wavelength relationship to assign one wavelength to each effective detector position and corrected detector value.

Rationale: One wavelength per detector position preserves the relationship among position, corrected value, and reported wavelength.

Objective 2: Coverage evidence. Wavelength Mapping shall compare the resulting wavelength array with the 400-1000 nm target and retain residuals calculated from known reference wavelengths.

Rationale: Coverage and residual evidence show where the wavelength assignment is supported by reference measurements.

Objective 3: Output and diagnostics. Wavelength Mapping shall prevent the mapped record from advancing when the map is absent and shall report incomplete coverage and wavelength residuals.

Rationale: Blocking an absent map prevents detector positions from being reported with unsupported wavelength meaning.

Documentation Relationship

Validation	Behavior claim, local traceability state, open decisions, and evidence method.

Pipeline Boundary

UUID: 9FDA6ADC-41D8-4C77-9992-C819CA32917C

Summary: The Host PC wavelength-mapping system receives ordered, geometry-qualified corrected values and supplies wavelength-associated data and validation evidence before spectral correction and record assembly. Function form, polynomial order, coefficient format, extrapolation, uncertainty, and residual thresholds remain Not In Docs.
