## Summary\n- Normalize/enforce memory_id at gateway/workflow boundaries and tighten config helpers/tests.\n- Make JetStream sync_interval configurable across compose/k8s/helm, document durability tuning.\n- Wire safety-kernel Redis config so policy bundle fragments load (packs).\n- Improve guardrails demos (gateway env, worker readiness) and align docs.\n\n## Why\nReduce policy bypass risk, improve crash durability controls, and make docs/demo workflows reliable for users.\n\n## Testing\n- go test ./...\n- cordumctl up (docker compose)\n- tools/scripts/platform_smoke.sh (inside compose network)\n- tools/scripts/demo_guardrails.sh (inside compose network)\n\n## Notes\n- Demo flow uses CORDUM_API_BASE/CORDUM_GATEWAY when not on localhost.\n
