FLOCK PLATFORM — AUTOMATED VERSIONING MIGRATION REPORT
================================================================================

1. EXECUTIVE SUMMARY
--------------------
This report documents the migration of the Flock platform's versioning and release
workflow from a manual, error-prone versioning strategy (with versions hardcoded
across files) to a modern, fully automated, Git-tag-driven workflow. By combining
setuptools-scm at build time and importlib.metadata at runtime, we have established
a single source of truth for Flock's versioning, completely eliminating manual edits.

2. ARCHITECTURAL OVERVIEW
-------------------------
The new architecture manages versions dynamically throughout the package lifecycle:

  [ Git Tag: v1.1.0 ] ──> [ setuptools-scm (build time) ] ──> [ dist/*.whl & dist/*.tar.gz ]
                                                                       │
                                                                       ▼
  [ importlib.metadata (runtime) ] <───────────────────────────────────┘
         │
         ▼
  [ flock.__version__ / flock --version ]

3. FILES MODIFIED
-----------------
- pyproject.toml:
  * Removed static version attribute (`version = "1.1.0"`).
  * Added `dynamic = ["version"]` to designate version configuration.
  * Added `"setuptools-scm>=8.0.0"` in build-system requirements.
  * Configured `[tool.setuptools_scm]`.

- src/flock/__init__.py:
  * Replaced hardcoded `__version__ = "1.1.0"` with dynamic importlib metadata query:
    `version("flock-p2p")`.
  * Included a fallback mechanism returning `"0.0.0.dev0"` in case of PackageNotFoundError
    (e.g., in uninstalled development or scratch environments).

- .github/workflows/release.yml [NEW]:
  * Tag-triggered workflow activated on tags matching `v*`.
  * Orchestrates checkout (with full history), Ruff lint checks, mypy strict type verification,
    full pytest execution, wheel/sdist packaging, twine checks, PyPI uploading, and
    GitHub Release creation.

4. OLD VS. NEW APPROACH COMPARISON
----------------------------------
+--------------------------+-------------------------------------+-------------------------------------+
| Dimension                | Old Approach                        | New Approach (Migrated)             |
+--------------------------+-------------------------------------+-------------------------------------+
| Single Source of Truth   | None (hardcoded in multiple files)  | Git Tags (vX.Y.Z)                   |
| Release trigger          | Manual build & twine upload commands| Git tag push (git push --tags)      |
| Build version resolution | Static string in pyproject.toml     | Dynamic resolution via setuptools-scm|
| Runtime resolution       | Hardcoded __version__ string        | importlib.metadata.version()        |
+--------------------------+-------------------------------------+-------------------------------------+

5. VALIDATION STEPS EXECUTED
----------------------------
- Build Verification:
  * Ran `python -m build` which successfully invoked setuptools-scm to produce:
    - sdist: `dist/flock_p2p-1.1.1.dev0+g92a46d46d.d20260725.tar.gz`
    - wheel: `dist/flock_p2p-1.1.1.dev0+g92a46d46d.d20260725-py3-none-any.whl`
  * Verified that twine checks succeeded on all built assets.

- Code Quality Checks:
  * Ruff checks executed with zero errors.
  * Mypy strict checks (`mypy --strict src/`) passed with success.

- Test Suite Execution:
  * Executed the complete test suite (`pytest tests/ -v`). All 635 unit tests passed.

- Editable Installation Check:
  * Ran `pip install -e .` and confirmed that `flock.__version__` resolves the dynamic development
    version (`1.1.1.dev0+g92a46d46d.d20260725`) successfully without hardcoding.

6. ROLLBACK CONSIDERATIONS
--------------------------
If a rollback is required:
1. Re-add the static `version` field in `pyproject.toml`.
2. Re-hardcode the version string in `src/flock/__init__.py`.
3. Re-install the packages normally.

7. FINAL CERTIFICATION
----------------------
Flock now uses a fully automated, Git-tag-driven versioning and release system. Versioning
is dynamically managed from Git tags, eliminating version synchronization errors and manual
maintenance overhead for future releases.
