Problem

lib/formula-session.sh check_memory (line 48) calls the free command to check available memory:

avail_mb=$(free -m | awk '/Mem:/{print $7}')

The agents Docker image (Debian bookworm based) does not have procps installed, so free is not available:

/home/agent/disinto/lib/formula-session.sh: line 48: free: command not found

This crashes any agent that sources formula-session.sh (gardener, supervisor, planner, predictor, architect).

Proposed solution

Add procps to the Dockerfile:

RUN apt-get update && apt-get install -y procps && rm -rf /var/lib/apt/lists/*

Alternatively, make check_memory graceful when free is missing:

if ! command -v free &>/dev/null; then
  log "run: free not found, skipping memory check"
  return 0
fi

Both fixes are recommended — install the package and add the fallback.

Affected files

docker/agents/Dockerfile (add procps)
lib/formula-session.sh (add fallback in check_memory)

Acceptance criteria

check_memory works in the agents container
Gardener, supervisor, planner, predictor, architect can all start without crashing
