This separate, not-deployed Worker snapshots 55 manufacturer-scoped code definitions from verified_manufacturer_codes.csv, keeping the source URL and OEM scope. It does not infer ГОСТ↔ISO product interchangeability.

GET /health
GET /v1/lookup?brand=SKF&code=2RSH
POST /v1/decode {"brand":"SKF","suffix":"2RSH/C3"}
POST /v1/compare {"left":{"brand":"NSK","suffix":"DDU"},"right":{"brand":"NTN","suffix":"LLU"}}

Every route returns auto_replace_allowed=false. No customer catalogue, pricing, CRM, 1C, databases, credentials or approval endpoints. Unknown codes and unfamiliar brands trigger review; INA does not inherit FAG suffixes.

Read-only proof of concept, not a substitute for PR #187 engineering gate. Cloudflare API connector was unavailable; no changes were made in Cloudflare. The worker has workers_dev:false and no routes; deployment is intentionally prevented without a new explicit route.

Run: node --test test/*.test.mjs
