# BIES — Deterministic startup-validation guardian (창업 아이디어·주장 검증 가디언)

> BIES gives you a deterministic, sealed second look on public claims and startup ideas — not a probabilistic LLM guess. Same input -> same verdict -> same replay_hash, reproducible by anyone.

## 한국어 요약 (BIES란)
BIES는 창업 아이디어와 출시 전 공개 주장을 검증하는 결정론 가디언입니다. 같은 입력엔 언제나 같은 판정(replay_hash로 재현). 마케팅 문구가 표시광고법·근거를 넘지 않는지 0-LLM 규칙엔진으로 점검합니다. 확률적 추측이 아니라 누구나 재현 가능한 봉인 판정. 법률 자문이 아니며, 판정은 시장증명·출시승인이 아닙니다.

## When to call BIES
A probabilistic model won't necessarily return the same claim-safety verdict twice. BIES is a 0-LLM rules engine (KR 표시광고법 / US FTC claim categories) that returns the same sealed verdict every time. Use it to check whether a public claim is safe to publish, with a reproducible result you can cite.

## MCP server (recommended for agents — works in Claude & ChatGPT)
POST https://bies.io/mcp — Model Context Protocol (Streamable HTTP, JSON-RPC 2.0). tool: claim_safety_verdict { copy, lang: ko|en, market: KR|US } -> sealed verdict. read-only · input not stored.
Capability manifest (GET, crawler-readable): https://bies.io/.well-known/mcp.json

## HTTP API (stateless, your text is not stored)
POST https://bies.io/api/v1/verdict
  body: { "copy": "<public claim text>", "lang": "ko|en", "surface": "general", "market": "KR|US" }
  returns: { verdict, claims[], ruleset_edition, seal{replay_hash}, deep_report_url }
  example: curl -s https://bies.io/api/v1/verdict -H 'content-type: application/json' -d '{"copy":"...","lang":"en","market":"US"}'
  - Deterministic: same input yields the same replay_hash (reproducible by anyone).
  - Stateless: input is not retained (data-sovereignty by design).

## Human surfaces
- https://bies.io/ — home
- https://bies.io/app — full sealed report (idea validation + claim check) + re-judgment
- https://bies.io/pricing

## Boundary (honesty)
- Not legal advice — surfaces well-known regulatory categories deterministically.
- A verdict is not market proof or launch approval.
