# NetKingdom Security Infrastructure Boundary

The canonical document lives in the NetKingdom repository:

```text
net-kingdom/docs/secrets-engine-security-infrastructure-boundary.md
```

Local checkout path:

```text
/home/worsch/net-kingdom/docs/secrets-engine-security-infrastructure-boundary.md
```

This secrets-engine file is intentionally only a pointer. The canonical document
belongs to NetKingdom because it defines cross-system security infrastructure
responsibilities and boundaries across OpenBao, flex-auth, user-engine/key-cape,
ops-warden, ops-bridge, info-tech-canon, State Hub, and agents.

The accepted layer model and working companion, which this repository now
declares against as Engine / Lifecycle, live at:

```text
net-kingdom/canon/standards/security-layer-model_v0.7.md
net-kingdom/SECURITY-COMPANION.md
```

secrets-engine consumes that boundary and implements the secrets workflow,
catalog, stage policies, OpenBao apply/delivery mechanics, and evidence model
that the canonical document assigns to it.
