spakky-policy
spakky-policy는 YAML, TOML, JSON policy document를 typed canonical model로 로드합니다.spakky-auth의 RBAC, PBAC, ABAC-style 인가 규칙을 provider contribution으로 평가합니다.
설치
pip install spakky-auth spakky-policy spakky-fastapi
사용법
SPAKKY_POLICY_DOCUMENT_PATH가 YAML, TOML, JSON 문서를 가리키면 플러그인이 해당 문서를
DI-managed PolicyDocument로 로드합니다. 경로를 설정하지 않으면 비어 있는 policy document를
등록해 인가 요청을 안전하게 거부합니다.

Policy 의미
- 명시적 deny statement는 matching allow statement보다 우선합니다.
- matching allow statement가 없으면 default deny evidence를 반환합니다.
- condition은
all,any,notcomposition과equals,not_equals,in,contains,existsatomic operator를 지원합니다. - resource, action, tenant ref는 decorator metadata,
AuthContext, resolver output, 또는 provider-neutralAuthorizationRequest에서 온 canonical string입니다. - named policy가 OR/ANY 사용자 표면입니다. MCP/tool authorization, generic policy API, policy UI, authorized data filtering은 이 패키지 범위 밖입니다.
