Calibration lookup borrows coefficients from another matrix · case 03
Calibration lookup borrows coefficients from another matrix.
Case contract
Given unique [lot,matrix,slope] records, return the slope for an exact pair or None. No fallback between lots or matrices.
Why this case matters
A deterministic synthetic laboratory reporting model isolates a software metadata contract; it is not a clinical procedure.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| same lot different matrix | 3 | 5 | Failed |
