Typed pydantic-settings config, structlog JSON logging with request/trace id propagation and redaction of phone numbers, tokens and face keys, the unified response envelope and error-code table from 架构文档 §9.2, async SQLAlchemy session management, ORM models for the eight foundation tables, and the OpenTelemetry/Prometheus wiring. packages/domain stays pure logic -- snowflake ids, the quota three-phase protocol and the tk_task state machine -- so it can be tested without a database and is held to mypy strict.
