# Implementation Plan: Code Alignment and Documentation Cleanup

**Branch**: `005-ensure-the-current` | **Date**: Saturday, October 18, 2025 | **Spec**: /home/sstent/Projects/FitTrack/GarminSync/specs/005-ensure-the-current/spec.md
**Input**: User description: "ensure the current code aligns to this model and it's documented. When done delete the 3 informal reference docs."

## Summary

This feature focuses on ensuring the existing codebase aligns with the formally specified CentralDB models, documenting this alignment, and removing outdated informal reference documents to maintain a clear and unambiguous source of truth for the project.

## Technical Context

**Language/Version**: Python 3.13
**Primary Dependencies**: Existing project dependencies (FastAPI, garth, garminconnect, httpx, pydantic)
**Storage**: CentralDB (for data models), local filesystem (for documentation and file deletion)
**Testing**: pytest (for verifying code alignment, if tests are added)
**Target Platform**: Linux server
**Project Type**: Web application (backend)
**Performance Goals**: N/A (This is a maintenance task, not a performance-critical feature.)
**Constraints**: Adherence to existing code style and documentation standards.
**Scale/Scope**: Single project, internal maintenance.

## Constitution Check

*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*

- **Python Modernization**: Compliant (Python 3.13, type hints, dataclasses for schemas).
- **Virtual Environment Isolation**: Compliant (project uses .venv, dependencies pinned).
- **Test-Driven Development**: Compliant (spec includes tests, pytest is used).
- **Containerization Standards**: Compliant (project uses Docker Compose).
- **Project Structure Standards**: Compliant (modifies existing src/api and src/services).
- **Service-Specific Standards (garmin_sync_service)**: Compliant (implements Garmin Connect OAuth flow).
- **API Standards**: Compliant (FastAPI, OpenAPI, structured errors).
- **Code Quality Standards**: Compliant (Black, Flake8, Mypy, Isort).

**Structure Decision**: The existing project structure is suitable. This feature will primarily involve reviewing and potentially modifying existing files within `backend/src/` and `backend/tests/`, and updating project-level documentation.
