+ODYSSEUS DOCKER START/STOP (WINDOWS)
+
+REQUIREMENT
+Docker Desktop must be installed, running, and ready before these scripts are used.
+The scripts expect the repository at C:\odysseus and bind Odysseus to
+http://127.0.0.1:7000.
+
+START WITH A VISIBLE WINDOW
+Double-click:
+ scripts\start_odysseus_docker.bat
+
+START HIDDEN
+Double-click:
+ scripts\start_odysseus_docker_hidden.vbs
+
+The hidden launcher starts the same batch script without showing a console.
+Startup details are appended to:
+ logs\odysseus-docker-startup.log
+
+STOP
+Double-click:
+ scripts\stop_odysseus_docker.bat
+
+This runs "docker compose stop" for the standard stack. It does not run
+"docker compose down", delete containers, volumes, images, or application data.
+Stop details are appended to:
+ logs\odysseus-docker-stop.log
+
+STATUS AND LOGS (POWERSHELL)
+ Set-Location C:\odysseus
+ docker compose ps
+ docker compose logs --tail 100 odysseus
+ docker compose logs --tail 100 searxng chromadb ntfy
+
+PERSISTENCE
+Application data and logs remain under C:\odysseus\data and C:\odysseus\logs.
+SearXNG, ChromaDB, ntfy, and the disposable workbench use Docker named
+volumes. The stop script preserves all of them.
+
+REBUILD AFTER SOURCE CHANGES
+Changes made in C:\odysseus (mounted as /project/workspace) do not change the
+running application snapshot at /app. After reviewing and testing changes, rebuild and
+recreate Odysseus from Windows PowerShell:
+ Set-Location C:\odysseus
+ $env:APP_BIND = "127.0.0.1"
+ $env:APP_PORT = "7000"
+ docker compose up -d --build --no-deps odysseus
+ Remove-Item Env:APP_BIND -ErrorAction SilentlyContinue
+ Remove-Item Env:APP_PORT -ErrorAction SilentlyContinue
+
+WORKSPACE AND DISPOSABLE WORKBENCH
+Select /project as the single active Odysseus workspace. The real Windows
+checkout is mounted read/write at /project/workspace, while the running app
+stays at /app. A Docker named volume is mounted at /project/workbench for
+disposable sandbox-first patch work. Do not copy .env, data, logs, credentials,
+model caches, or other secrets into the workbench. Test candidate changes
+there, then apply the reviewed patch to /project/workspace and test again before
+rebuilding.
+
+ROLLBACK TO THE NATIVE WINDOWS LAUNCHER
+The original native scripts are preserved:
+ scripts\start_odysseus.bat
+ scripts\start_odysseus_hidden.vbs
+ scripts\stop_odysseus.bat
+
+Before starting native Odysseus, stop the Docker stack and confirm port 7000 is
+free. Do not run the native and Docker versions on the same host port.
+
+SAFETY
+The standard Compose configuration does not mount the Docker socket. Do not add
+the host-Docker overlay merely to use these scripts. Windows Firewall changes
+are outside these scripts.
