+# CCCS Advisory Connector
+
+## Module
+Concelier
+
+## Status
+IMPLEMENTED
+
+## Description
+Canadian Centre for Cyber Security (CCCS) advisory connector with HTML parsing, raw document mapping, and scheduled job ingestion. The known list has "Cross-Distro Advisory Connectors" and "Advisory Connector Architecture (NVD, OSV, GHSA, Vendor Feeds)" but not CCCS specifically.
+
+## Implementation Details
+- **Modules**: `src/Concelier/__Libraries/StellaOps.Concelier.Connector.Cccs/`
+- **Key Classes**:
+  - `CccsConnector` (`src/Concelier/__Libraries/StellaOps.Concelier.Connector.Cccs/CccsConnector.cs`) - `IFeedConnector` implementation for CCCS advisory feed ingestion
+  - `CccsConnectorPlugin` (`src/Concelier/__Libraries/StellaOps.Concelier.Connector.Cccs/CccsConnectorPlugin.cs`) - `IConnectorPlugin` registration for DI discovery
+- **Orchestration**: `ConnectorRegistrationService` (`src/Concelier/__Libraries/StellaOps.Concelier.Core/Orchestration/ConnectorRegistrationService.cs`) - discovers and registers the CCCS plugin
+- **Interfaces**: `IFeedConnector`, `IConnectorPlugin`
+- **Source**: Sprint 0117 (batch_14/file_18.md)
+
+## E2E Test Plan
+- [ ] Trigger CCCS connector ingestion and verify advisory documents are fetched and mapped to canonical format
+- [ ] Verify `CccsConnectorPlugin` is discovered by `ConnectorRegistrationService` during startup
+- [ ] Verify HTML parsing: submit a sample CCCS HTML advisory and verify fields are correctly extracted
+- [ ] Verify scheduled ingestion: confirm the connector runs on its configured schedule via `ConnectorWorker`
