# Model Inventory Entry Builder

`POST /v1/tools/build_model_inventory_entry`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/build_model_inventory_entry`
- Auth: none declared

Builds a single model-inventory record for a bank's SR 26-2 model-risk-management inventory: checks the caller-declared attributes (model name, owner, purpose, tier, development/deployment dates, last validation date) against the SR 26-2 required-field set, assigns a proportionality tier (limited/moderate/high) from caller-declared materiality and complexity inputs, and returns a completeness score plus a list of missing required fields. First node in the model-passport lifecycle (inventory entry, then outcome-analysis comparison in art-451, then validation status in art-453). 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, not a single model's inventory record. Distinct from art-380 (AI workpaper record), which documents a completed assessment rather than registering a model. NaN-safe. Zero network, zero PII.
