+## 15. Build & Deployment Strategy
+Because the background server operates as an always-on Windows daemon, standard recompilation and file-copying strategies will fail due to active Windows OS file locks. 
+
+### Randomized Lock Bypassing
+The \uild.ps1\ deployment pipeline intercepts locked \.exe\ files by appending a unique, timestamped/randomized suffix (e.g., \mcp-memory-server.exe.12345.old\) when forcing a \Move-Item\. This guarantees that rapid sequential deployments (where a previous \.old\ file might still be locked by a zombie process) never silently fail or collide.
+
+### Dynamic Versioning
+To trace binary provenances during rapid deployment cycles, all binaries embed dynamic versioning directly at compile time (via \uild.rs\ and \uild_template.rs\). The injected \APP_VERSION\ environment variable combines the static Cargo \ersion\ with the live \git\ short hash and UTC timestamp, allowing the CLI \--version\ commands and the HTTP \/api/version\ endpoints to guarantee exactly which iteration of the code is actively executing.
