//! Integration tests for inverse calibration algorithm (Story 19.1 / P4-25).
|
|
//!
|
|
//! Tests cover:
|
|
//! - Single-factor calibration (f_ua → target capacity)
|
|
//! - Multi-factor sequential calibration (f_m then f_ua)
|
|
//! - Simultaneous calibration
|
|
//! - Failure diagnostics
|
|
//! - Bounds enforcement
|
|
//! - JSON round-trip of CalibrationResult
