# Model Outcome-Analysis Comparison

`POST /v1/tools/compare_model_outcome_analysis`

## Request

- Auth: none declared

SR 26-2 ongoing-monitoring backtest: compares a list of period predicted-vs-actual model outcomes, computes per-period absolute percent error, mean/max absolute percent error, and flags periods breaching a caller-declared error tolerance. Returns a pass/fail outcome status against a caller-declared maximum breach rate. Second node in the model-passport lifecycle (after art-450 inventory entry, before art-453 validation status). Distinct from the shipped program-level gap analyzers (tools 339/451 SR 26-02 and SR 11-7 gap assessors), which score an institution's overall MRM program rather than backtest one model's outcomes. NaN-safe. Zero network, zero PII.
