+# Advisory Connector Architecture (NVD, OSV, GHSA, Vendor Feeds)
+
+## Module
+Concelier
+
+## Status
+VERIFIED
+
+## Description
+Extensive advisory connector ecosystem with vendor-specific connectors for VMware, Oracle, MSRC, Cisco, Chromium, Apple, plus NVD, OSV, GHSA, RedHat, SUSE, Debian, Alpine, Ubuntu, KEV, EPSS, CERT-FR, CERT-CC, CERT-Bund feeds.
+
+## Implementation Details
+- **Modules**: `src/Concelier/__Libraries/StellaOps.Concelier.Connector.*`, `src/Concelier/__Connectors/`, `src/Concelier/StellaOps.Concelier.Plugin.Unified/`
+- **Key Classes**:
+  - **Plugin System**: `FeedPluginAdapterFactory`, `FeedPluginAdapter` (`src/Concelier/StellaOps.Concelier.Plugin.Unified/`) - unified plugin adapter for `IConnectorPlugin` implementations
+  - **Orchestration**: `ConnectorRegistrationService` (`src/Concelier/__Libraries/StellaOps.Concelier.Core/Orchestration/ConnectorRegistrationService.cs`) - discovers and registers connector plugins
+  - `ConnectorWorker` (`src/Concelier/__Libraries/StellaOps.Concelier.Core/Orchestration/ConnectorWorker.cs`) - executes connector ingestion cycles
+  - **Vendor Connectors**: `CiscoConnector`, `VmwareConnector`, `OracleConnector`, `MsrcConnector`, `AppleConnector`, `ChromiumConnector`, `AdobeConnector` (each in `src/Concelier/__Libraries/StellaOps.Concelier.Connector.Vndr.*`)
+  - **Feed Connectors**: `NvdConnector`, `OsvConnector`, `GhsaConnector`, `EpssConnector`, `KevConnector`, `CveConnector` (each in `src/Concelier/__Libraries/StellaOps.Concelier.Connector.*`)
+  - **CERT Connectors**: `CertBundConnector`, `CertFrConnector`, `CertCcConnector`, `CertInConnector` (each in `src/Concelier/__Libraries/StellaOps.Concelier.Connector.Cert*`)
+  - **Distro Connectors**: `AlpineConnector`, `DebianConnector`, `RedHatConnector`, `SuseConnector`, `UbuntuConnector` (each in `src/Concelier/__Libraries/StellaOps.Concelier.Connector.Distro.*`)
+  - **Regional Connectors**: `AcscConnector`, `KisaConnector`, `JvnConnector`, `IcsCisaConnector`, `KasperskyConnector`, `RuBduConnector`, `RuNkckiConnector`, `AstraConnector`, `StellaOpsMirrorConnector`
+- **Interfaces**: `IFeedConnector`, `IConnectorPlugin`
+- **Source**: Feature matrix scan
+
+## E2E Test Plan
+- [ ] Verify `ConnectorRegistrationService` discovers all connector plugins via DI
+- [ ] Trigger a connector ingestion cycle via `ConnectorWorker` for NVD and verify advisories are stored
+- [ ] Verify GHSA connector fetches GitHub Security Advisories and maps to canonical format
+- [ ] Verify EPSS connector fetches exploit prediction scores and associates with CVE IDs
+- [ ] Verify at least one vendor connector (e.g., Cisco) fetches vendor-specific advisories
+- [ ] Verify at least one distro connector (e.g., Debian) fetches distro-specific patch data
