 ## How to request a scan
 
-Titan is configured (by Terraform) to respond to scan requests for the `public` and
-`secure` storage buckets. To request a scan, tag the object with the following metadata
-after uploading it:
+To request a scan from Siarnaq, use the `titan.request_scan()` function with a blob:
 
-```
-Titan-Status: Unverified
+```python
+from siarnaq.gcloud import titan
+
+# After uploading a file to GCS
+titan.request_scan(blob)
 ```
 
-Titan will detect this and scan the file. Once the file is scanned, the status will be
-replaced with either of `Verified` or `Malicious`.
+This function:
+1. Sets the blob's metadata to `Titan-Status: Unverified`
+2. Publishes a scan request message to the Pub/Sub topic
+
+Once the file is scanned, Titan updates the metadata status to either `Verified` or
+`Malicious`. The status can be checked using `titan.get_object()`.
 
 ## System architecture
 
-Titan receives file metadata update events via Google EventArc. These events are pushed
-to the server and the file is scanned.
+Titan receives scan requests via Google Cloud Pub/Sub:
+
+1. **Siarnaq** publishes scan request messages to the `{environment}-siarnaq-scan` topic
+2. **Pub/Sub** pushes these messages to Titan's Cloud Run service via OIDC-authenticated HTTP POST
+3. **Titan** processes the message, retrieves the file from GCS, scans it with ClamAV, and updates the file's metadata
+
+The message payload is a simple JSON object:
+```json
+{
+  "bucket": "bucket-name",
+  "name": "path/to/file"
+}
+```
+
+Titan runs on Cloud Run and scales automatically based on incoming Pub/Sub push requests.

 Titan is our antivirus module that performs asynchronous malware scanning on-demand.
 
+## Development
+
+### Running Tests
+
+To run the unit tests locally:
+
+```bash
+cd titan
+go test -v ./pkg/...
+```
+
+To run tests with coverage:
+
+```bash
+go test -v -coverprofile=coverage.out ./pkg/...
+go tool cover -html=coverage.out  # View coverage in browser
+```
+
+To run tests with race detection:
+
+```bash
+go test -v -race ./pkg/...
+```
+
+The tests are automatically run as part of CI on every pull request.

 ## How to request a scan
 
 To request a scan from Siarnaq, use the `titan.request_scan()` function with a blob:

 ### Running Tests
 
-To run the unit tests locally:
+#### Unit Tests (Fast, No Dependencies)
+
+Run the fast unit tests with mocked dependencies:
+
+```bash
+cd titan
+go test -v -short ./pkg/...
+```
+
+#### Integration Tests (Requires ClamAV)
+
+The integration tests require ClamAV to be installed and running. These tests verify the actual scanning functionality with a real clamd daemon.
+
+**Install ClamAV:**
+
+```bash
+# Ubuntu/Debian
+sudo apt-get install clamav clamav-daemon
+
+# macOS
+brew install clamav
+```
+
+**Start ClamAV daemon:**
+
+```bash
+# Ubuntu/Debian
+sudo systemctl start clamav-daemon
+
+# macOS
+# Edit /opt/homebrew/etc/clamav/clamd.conf if needed
+clamd
+```
+
+**Run integration tests:**
 
 ```bash
 cd titan
 go test -v ./pkg/...
 ```
 
-To run tests with coverage:
+**Run all tests with coverage:**
 
 ```bash
 go test -v -coverprofile=coverage.out ./pkg/...
 go tool cover -html=coverage.out  # View coverage in browser
 ```
 
-To run tests with race detection:
+**Run tests with race detection:**
 
 ```bash
 go test -v -race ./pkg/...
 ```
 
-The tests are automatically run as part of CI on every pull request.
+The tests are automatically run as part of CI on every pull request. The CI pipeline caches the ClamAV virus definitions to speed up test execution.

-The tests are automatically run as part of CI on every pull request. The CI pipeline caches the ClamAV virus definitions to speed up test execution.
+The tests are automatically run as part of CI on every pull request. The CI pipeline uses a minimal custom test database (only EICAR signature) rather than downloading the full ~8GB ClamAV database set. This keeps CI execution fast while still validating real scanning functionality.
