Conversation
…guard Add a pluggable prompt-injection guard subsystem backed by danger.ScanInjection locally and an optional go-prompt-injection-guard sidecar (HTTP/Unix). Covered surfaces: - memory (legacy facts, memory tool writes, Extended Memory atoms/recall) - system_prompt (IDENTITY.md, --system, AGENTS.md) - mcp_descriptions - skills (load, save, patch suggestions) - telegram (captions, transcripts) - tool_outputs (warning-only) Includes config/env/CLI wiring, tests, and doc updates.

- Add piguard (daemon) and piguard-gateway (HTTP bridge) services to all odek docker-compose profiles. - Mount a read-only ./piguard/models volume for the one-time-exported ONNX model and add docker/piguard/download-model.sh to populate it. - Wire bundled config.restricted.json and config.godmode.json to point the guard at http://piguard-gateway:8080/detect. - Document setup, optional surfaces, and how to disable the sidecar in docker/README.md.

What
Adds a pluggable prompt-injection guard subsystem. The built-in local rule scan (
danger.ScanInjection) always runs first; an optionalgo-prompt-injection-guardsidecar provides a second opinion when configured.Covered surfaces

The compose stack now includes a PIGuard sidecar:
piguard— the daemon that loads the ONNX model.piguard-gateway— an HTTP bridge so odek uses its existing HTTP-based guard client.docker/piguard/download-model.sh— one-time model export script (~735 MB).config.*.jsonfiles point the guard athttp://piguard-gateway:8080/detect.Run
