 # COMcheck API — Python Package

+# Compliance, Requirements & Reports Reference
+
+Three client methods evaluate a project without running the full
+async simulation flow. All three accept a `ComBuilding` and serialize
+it for you — pass the project model directly.
+
+```python
+from comcheck_api import COMcheckClient
+client = COMcheckClient(api_key="...")
+```
+
+| Method | Returns | Purpose |
+|---|---|---|
+| `client.check_UA_compliance(project)` | `dict` | Per-category compliance status for the project. |
+| `client.check_requirements(project)` | `dict` | The applicable requirements for the project. |
+| `client.generate_report(project, ...)` | `dict` | Generate a PDF report; returns `{url, expires, fileName}`. |
+
+## check_UA_compliance
+
+Returns a dict with a top-level `mandatoryRequirementsMet` flag and a
+status object for each category:
+
+- `envelopeStatus`
+- `interiorLightingStatus`
+- `exteriorLightingStatus`
+- `renewableStatus`
+- `energyCreditStatus`
+
+```python
+compliance = client.check_UA_compliance(project)
+if compliance["mandatoryRequirementsMet"]:
+    ...
+```
+
+## check_requirements
+
+Returns the applicable requirements payload for the project. Like
+`check_UA_compliance`, it's a single synchronous call — no polling.
+
+```python
+requirements = client.check_requirements(project)
+```
+
+## generate_report
+
+Builds a PDF report. The PDF is stored in S3; the API returns a
+**short-lived presigned URL** (expires within a few minutes) plus the
+file name:
+
+```python
+report = client.generate_report(project)
+# {"url": "...", "expires": "in 5 minutes", "fileName": "report...pdf"}
+```
+
+### Signature
+
+```python
+client.generate_report(
+    project,
+    envelope=True,
+    extlighting=True,
+    intlighting=True,
+    mechanical=True,
+    download=False,
+    download_dir=None,
+)
+```
+
+- The four section flags toggle which sections appear in the report
+  (all default to `True`).
+- `download=True` fetches the PDF from the presigned URL and saves it
+  using the server-provided `fileName`. `download_dir` defaults to the
+  user's `~/Downloads` folder.
+
+```python
+report = client.generate_report(project, download=True)                      # ~/Downloads
+report = client.generate_report(project, download=True, download_dir="./out")
+```
+
+## Don't
+
+- Don't try to open the report in a browser from library code — this
+  method intentionally returns metadata only. If a browser is wanted,
+  the caller does `webbrowser.open(report["url"])`.
+- Don't cache the presigned `url` — it expires within minutes.
+  Re-call `generate_report` to get a fresh one.

+## U-value calculation requires a construction type
+
+When `update_uvalues` (or `start_run_simulation`) recalculates assembly
+u-values, the engine needs a valid construction-type field to classify
+each assembly — `roofType` for roofs, `wallType` for walls, etc. If it's
+missing or null, the engine falls back to an `"Other"` classification,
+returns a `propUValue` of `0.0`, and the response comes back with
+`assemblyType: "Other"` instead of the value you sent. Because the client
+matches results back by `assemblyType`, an `"Other"` result won't match
+your assembly and its u-value is silently left unchanged.
+
+The default templates set these fields (e.g. `roofType=ABOVE_DECK_ROOF`),
+so this only bites when you build an assembly by hand or clear the type.
+Keep the construction-type field populated:
+
+```python
+from comcheck_api.types import RoofTypeOptions
+
+roof.roofType = RoofTypeOptions.ABOVE_DECK_ROOF   # don't leave this null
