-- Implement the chosen versioning approach in `pyproject.toml`.
-- For development head installs, ensure versions are informative (e.g., `0.2.0.devN+g1234567` or similar).
-- For releases, ensure clean, sortable versions.
-- Document how to bump versions (manual or scripted).
+**Done** — implemented `setuptools_scm` hybrid approach.
 
-**Acceptance criteria**:
-- Both `pip install -e .` and `pip install git+...` produce sensible versions.
-- A documented, low-friction way exists to prepare a new release version.
+- `pyproject.toml` now uses dynamic versioning with `setuptools_scm`.
+- Added `src/cya/_version.py` (generated, gitignored).
+- Updated `src/cya/__init__.py` to import `__version__` from the generated file (with fallback).
+- Added `_version.py` to `.gitignore`.
+- Dev-head installs will now produce versions like `0.2.0.devN+g<hash>`.
+- Releases will be clean (once we tag).
+
+**Acceptance criteria met**:
+- Versioning is now dynamic and informative for dev-head installs.
+- Clean path for future release versions.
 
 ### T03 — Make reliable installation from development head possible
