formula_id: WBS_10_DOTNET_IDEMPOTENCY_CONTRACT_V1
owner: QuantEngine
status: draft
goal: "중복 실행 방지, lock/lease 정책, 재시도 경계를 표준화한다."
lock_domain:
canonical_table: quantengine.workspace_lock
fields:
- domain
- target_ref
- locked_by
- reason
- locked_at
invariant:
- "같은 domain + target_ref 조합은 동시에 하나만 존재"
- "잠금 해제는 동일 domain + target_ref 로만 수행"
- "잠금 없는 실행은 retryable 작업으로 취급하지 않는다"
idempotency_key:
required: true
pattern: "{job_id}:{resource_key}:{run_scope}"
scope_examples:
- "daily-collection:collection:yyyyMMdd"
- "hourly-price-update:ticker:yyyyMMddHH"
- "weekly-report:report:yyyy-'W'ww"
- "monthly-optimization:optimization:yyyy-MM"
lease_policy:
required: true
fields:
- lease_owner
- timeout_policy
- retry_policy
retry_policy:
max_attempts: 3
backoff: exponential
retryable_errors:
- transient network failure
- upstream timeout
- deadlock detected
non_retryable_errors:
- validation failure
- contract failure
- missing configuration
duplicate_execution_guards:
- "동일 job_id/resource_key/run_scope 중복 호출 금지"
- "동일 lock_domain이 점유 중이면 새 실행은 blocked"
- "중복 실행이 발생하면 audit는 남기되 write path는 재진입 금지"
notes:
- "idempotency는 hash 추정이 아니라 명시된 key 조합만 사용한다."
- "lock은 수동 승인 워크플로와 동일한 canonical table을 사용한다."
