# PQC Migration Roadmap Builder

`POST /v1/tools/build_pqc_roadmap`

## Request

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

Build a phased PQC migration roadmap per system. Maps current algorithm to FIPS 203/204/205 replacement by use case (key_exchange/TLS→ML-KEM, signature→ML-DSA+SLH-DSA, symmetric→AES-256, hash→SHA-384). Assigns Phase 1–4 windows by hndl_priority. Supports hybrid mode and target security category. Step 3 of the PQC Migration chain.

**Tool URL:** https://ainumbers.co/tools/501-pqc-migration-roadmap-builder.html
**AP2/Policy Mandate export:** yes
