+
+## Project overview
+
+Official Python SDK for the Verda Cloud API (formerly DataCrunch). The main package is `verda`, with a backward-compatible `datacrunch_compat` wrapper that re-exports everything under the old `datacrunch` name.
+
+- **Package name:** `verda` (PyPI)
+- **Python:** >= 3.10, tested on 3.10 through 3.14
+- **License:** Apache 2.0
+- **Build system:** `uv_build`
+
+## Common commands
+
+```bash
+uv sync                          # install dependencies
+uv run pytest                    # run all tests (unit + integration)
+uv run pytest tests/unit_tests   # run unit tests only
+uv run ruff check                # lint
+uv run ruff format --check       # check formatting
+uv run ruff format               # auto-format
+```
+
+CI runs three checks on every PR: unit tests (Python 3.10-3.14), `ruff check`, and `ruff format --check`.

+
+## Module conventions
+
+Each service module follows this pattern:
+
+```
+verda/<service>/
+  __init__.py           # public exports only (no license header)
+  _<service>.py         # all implementation: dataclasses, service class, endpoint constant
+```
+
+- The `__init__.py` only re-exports public symbols from the private `_<service>.py` module.
+- `__init__.py` files do NOT have the Apache 2.0 license header. All other `.py` files do.
+- Implementation files are prefixed with `_` (e.g., `_instances.py`, `_volumes.py`).
+
+## Code style
+
+### Formatting and linting
+
+- **Tool:** Ruff (lint + format)
+- **Line length:** 100 characters
+- **Quote style:** single quotes
+- **Docstring convention:** Google style
+- **Import sorting:** handled by ruff (`I` rules)
+
+### Ruff rules enabled
+
+`E4, E7, E9, F, C4, I, PT, B, UP, D, A, ARG, RUF`
+
+Key rule groups: default pyflakes/pycodestyle, comprehensions, import sorting, pytest conventions, bugbear, Python syntax upgrades, pydocstyle (Google), builtins shadowing, unused args, ruff-specific.
+
+Ignored: `F401` (unused imports), `B006` (mutable default args), `D100` (module docstring), `D105` (magic method docstring), `D107` (`__init__` docstring).
+
+Per-file ignores:
+
+- `tests/`, `examples/`, `datacrunch_compat/tests/` -- all `D` rules (docstrings not required)
+- `__init__.py` -- `D104` (missing package docstring)
+- `datacrunch_compat/datacrunch/*.py` -- `F403` (wildcard imports allowed)
+
+### Type hints
+
+- Use Python 3.10+ union syntax: `str | None` (not `Optional[str]`)
+- Type-annotate function signatures and return types
+- Use `Literal` for constrained string values (e.g., `Contract = Literal['LONG_TERM', 'PAY_AS_YOU_GO', 'SPOT']`)
+
+### Dataclasses
+
+- Use `@dataclass_json` decorator from `dataclasses_json` for JSON serialization
+- Use `@dataclass_json(undefined=Undefined.EXCLUDE)` for API response models (tolerates extra fields)
+- Stack decorators: `@dataclass_json` first, then `@dataclass`
+- Optional fields use `field(default=None)` or `= None`
+- Google-style docstrings with `Attributes:` section
+
+### License header
+
+All `.py` files (except `__init__.py`) must have this header at the top:
+
+```python
+# Copyright 2026 Verda Cloud Oy
+#
+# Licensed under the Apache License, Version 2.0 (the "License");
+# you may not use this file except in compliance with the License.
+# You may obtain a copy of the License at

+# distributed under the License is distributed on an "AS IS" BASIS,
+# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
+# See the License for the specific language governing permissions and
+# limitations under the License.
+```
+
+Ensure two blank lines between the header and the first top-level `class`/`def` (ruff enforces this).
+
+## Testing conventions
+
+- **Framework:** pytest
+- **HTTP mocking:** `responses` library (via `pytest-responses`)
+- **Test organization:** class-based, one test class per service (e.g., `TestVolumesService`)
+- **Fixture pattern:** shared `http_client` fixture in `conftest.py` using `unittest.mock.Mock` for auth
+- **Per-test fixtures:** `<service>_service` and `endpoint` fixtures defined inside each test class
+- **Naming:** `test_<action>_<successful|failed>` (e.g., `test_create_volume_successful`, `test_create_volume_failed`)
+- **Structure:** arrange/act/assert pattern with `# arrange`, `# act`, `# assert` comments
+- **API error tests:** use `pytest.raises(APIException)` and verify `.code` and `.message`
+- **Request matching:** use `responses.add()` with `matchers.json_params_matcher()` to verify request payloads
+- **Test data:** define constants and mock payloads as module-level variables at top of test file
+
+## Git and branching
+
+- **Main branch:** `master`
+- **Branch naming:** `feature/<name>` for features, `fix/<name>` for bugfixes
+- **PRs:** tests must pass on all supported Python versions before merge
+
+## Release process
+
+1. `uv version --bump minor` (or `major`/`patch`)
+2. Update `CHANGELOG.md`
+3. Commit, tag with `v<version>`, push to `master` with tags
+4. Publish via GitHub release (triggers PyPI publish workflow)
+
+## Dependencies
+
+- **Runtime:** `requests` (HTTP), `dataclasses_json` (serialization)
+- **Dev:** `pytest`, `pytest-cov`, `pytest-responses`, `responses`, `python-dotenv`, `ruff`
+
+* IMPORTANT: Never jump directly to the conclusion. First think about constraints and considerations before answering. This applies to all questions including ones that look simple, practical, obvious or straightforward. Labeling a question as not needing analysis is itself a failure mode.

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
