Testing: Stabilized test suite and achieved 93% total coverage.

- Fixed CLI tests by patching local imports at source (psutil, os, Path).
- Fixed Collector tests by globalizing docker.from_env mock.
- Stabilized SSE stream tests via AsyncMock and immediate generator termination to prevent hangs.
- Achieved >80% coverage on CLI (84%), Collector (97%), and DB Repository (100%).
- Implemented SMTP Relay service tests (100%).

+# DECNET Execution Graphs
+
+These graphs illustrate the logical flow of execution within the DECNET framework, showing how high-level commands and API requests trigger secondary processes and subsystem interactions.
+
+## 1. Deployment & Teardown Flow
+This flow shows the orchestration from a CLI `deploy` command down to network setup and container instantiation.
+
+```mermaid
+graph TD
+    CLI_Deploy([cli.deploy]) --> INI[ini_loader.load_ini]
+    CLI_Deploy --> NET_Detect[network.detect_interface]
+    CLI_Deploy --> FleetBuild[fleet.build_deckies_from_ini]
+    
+    FleetBuild --> Archetype[archetypes.get_archetype]

+    Engine_Teardown --> NET_Cleanup[network.teardown_host_macvlan]

+```
+
+## 2. Mutation & Monitoring Flow
+How DECNET maintains deception by periodically changing decoy identities and monitoring activities.
+
+```mermaid
+graph LR
+    subgraph Periodic_Process
+        CLI_Mutate([cli.mutate]) --> Mutate_Loop[mutator.engine.run_watch_loop]

+    Mutate_Decky --> Restart_Container[engine.deployer._compose_with_retry]

+        Worker --> Stream[collector.worker._stream_container]
+        Stream --> Parse[collector.worker.parse_rfc5424]
+    end
+```
+
+## 3. Web API Flow (Fleet Management)
+How the Web UI interacts with the underlying systems via the FastAPI router.
+
+```mermaid
+graph TD
+    Web_UI[Web Dashboard] --> API_Deploy[web.router.fleet.deploy_deckies]
