## role
This package archives a completed 2026 structural refactoring specification that reorganized a Python/FastAPI backend and TypeScript frontend monolith into domain-based subpackages with extracted schemas and standardized naming conventions.
## files
- .openspec.yaml | Defines an OpenSpec configuration file with schema version and creation date metadata
- design.md | A design document specifying a large-scale backend/frontend refactoring to split monolithic modules into domain-based subpackages, extract schemas, and standardize naming conventions. | dep: FastAPI, Pydantic, SQLAlchemy, Docker, React/TypeScript, Git
- proposal.md | Proposes a pure structural refactoring of a codebase to extract schemas, split monolithic services, refactor auth dependencies, and reorganize frontend files without changing behavior.
- spec.md | This file defines a pure structural refactoring specification for extracting schemas, splitting service monoliths, reorganizing frontend code, and enforcing file size limits without changing any behavior or API contracts. | dep: Pydantic, FastAPI, SQLAlchemy, Docker Compose, React/TypeScript, ruff, npm
- tasks.md | A phased project roadmap for reorganizing a Python/FastAPI backend and TypeScript frontend codebase into domain-based subpackages with verification steps | dep: Python, FastAPI, Pydantic, Docker, ruff, py_compile, pytest, npm, TypeScript, React
## arch
Document-driven specification architecture using phased task breakdown (OpenSpec YAML metadata + layered markdown docs: design → proposal → spec → tasks) with behavior-preserving pure structural refactoring pattern enforced by file size limits and verification gates.
