# Thermoelectric temperature sensor calibration, drift, and cross-sensitivity evidence map

## Scope

This v105 packet teaches how a generic thermoelectric response, series-junction scaling, reference-junction correction, calibration slope and offset, ascending/descending hysteresis, repeatability, drift, mechanical burden, cross-sensitivity, uncertainty, traceability lineage, and replacement evidence must remain separate.

## Execution

- 6,144 deterministic rows.
- Complete `16 x 4 x 3 x 2 x 2 x 2 x 2 x 2` Cartesian product.
- Precomputed CSV and typed JSON with browser-only filtering.
- Original dimensionless equations and coefficients only.
- Zero publication values, NIST/BIPM tables or functions, physical units, measurement rows, calibration services, instrument control, or live server runs.

## Basic Identity Boundary

The packet uses only the generic teaching idea that thermoelectric output is proportional to a declared temperature-difference coordinate and contrast term, and that like-oriented series contributions add. The normalized contrast classes and all burdens are original assumptions. They are not a transcription of the 2026 graphene-fiber article, a NIST reference function, a BIPM temperature-scale realization, or a model of a thermocouple type.

## Calibration Boundary

`reference-tracked` means that a declared synthetic offset is removed inside the teaching model. It does not mean that a physical reference junction, cold-junction compensation, fixed point, comparison calibration, certificate, or traceability chain exists. `owned-calibration-slot-ready` means only that the record has a place for future owned evidence; it does not reduce uncertainty or create a calibration claim.

## Hysteresis, Repeatability, And Drift

Ascending and descending outputs are generated from a declared mechanical-burden coefficient. The gap is a stress-test field, not a measured loop. Repeatability is a deterministic burden score, while drift changes a synthetic slope and offset. Neither field is a statistical distribution, cycle test, aging model, stability forecast, or material result.

## Uncertainty Boundary

The packet combines declared normalized components with a root-sum-square transform and a fixed multiplier. This is useful for teaching that uncertainty components must remain visible, but it is not a GUM-compliant budget, calibration laboratory statement, confidence interval, or certificate. No NIST uncertainty value is copied.

## Medical And Product Boundary

The packet provides no body-temperature guidance, diagnosis, medical decision support, clinical interpretation, wearable-safety recommendation, product selection, material ranking, fabrication recipe, chemical-handling instruction, instrument-control action, qualification, or signoff.

## Source Addition

New sources enter through `SOURCE_ADDITION_WORKFLOW.md`. A source can add lineage, vocabulary, and evidence questions without changing model arithmetic. Any proposal to import a reported value or alter an equation, coefficient, threshold, unit, or interpretation requires a new metric-contract version, a regenerated packet, and a fresh no-import independent-verifier pass.

## Replacement Evidence

A real claim needs an owned measurand definition, reference-junction treatment, temperature reference, output and sampling records, calibration fit and valid range, residuals, repeatability, drift, ascending/descending tests, mechanical and nuisance studies, uncertainty budget, current traceability lineage, and accountable sensor/metrology review.
