## One-liner

Operational access steward for the NetKingdom security model — issues short-lived
SSH certificates for `adm`/`agt`/`atm` actors, documents how to obtain other
credential types from the right platform subsystems, and keeps ops access guidance
aligned with NetKingdom canon.

---

## Core Idea

**Today:** implements the SSH certificate lane from `wiki/AccessManagementDirective.md`
§§1–5 — CA signing, actor inventory, TTL policy, cert-side scorecard, and the
`cert_command` interface for ops-bridge.

**Direction (INTENT):** become the custodian-domain desk that understands NetKingdom
identity, authorization, secrets, and SSH lanes — routing dev workers to key-cape,
flex-auth, OpenBao, ops-bridge, and railiance components instead of centralizing
all secrets here.

Signing backends: `local` (ssh-keygen, labs) and `vault` (OpenBao or other
Vault-compatible SSH secrets engine API, production).

---

## In Scope

### Implemented (SSH lane)

- Local CA backend (`ssh-keygen -s`)
- OpenBao / Vault-compatible SSH engine backend
- Actor identity registry (`inventory.yaml`)
- `cert_command`: `warden sign <actor> --pubkey <path>` → cert on stdout
- TTL enforcement per `ActorType` (`adm` 48 h, `agt` 24 h, `atm` 8 h)
- `warden status`, cleanup, scorecard, signatures log
- `warden issue` and `ops-ssh-wrapper`
- Runbooks for OpenBao config and Inter-Hub bootstrap SSH envelope

### Stewardship (documentation and alignment)

- NetKingdom security routing guidance — which subsystem owns which credential type
- Wiki and config references aligned with OpenBao-first platform standard
- Capability registry entry for SSH certificate issuance
- Keeping ops access patterns consistent with `net-kingdom` platform architecture

### Stewardship (shipped WP-0006)

- `wiki/CredentialRouting.md` — credential type → subsystem routing
- `wiki/NetKingdomSecurityMap.md` — NetKingdom component literacy
- `wiki/ActorInventoryPatterns.md` + `examples/inventory.seed.yaml`
- `wiki/OpenBaoSshEngineChecklist.md` — production SSH signing verify
- `wiki/PolicyGatedSigning.md` — flex-auth integration (opt-in, WP-0007)

### Shipped (WARDEN-WP-0007)

- Opt-in flex-auth policy gate before `warden sign` / `warden issue` (`policy.enabled`)
- `policy_decision_id` in `signatures.log` when gate allows
- Production OpenBao health evidence (`history/2026-06-17-openbao-production-verify.md`)

### Active (WARDEN-WP-0008)

- End-to-end production OpenBao `warden sign` verification on Railiance (T2 — operator)
- `examples/warden.production.example.yaml` — production config template
- NK-WP-0009 SSH tutorial joint with net-kingdom (parallel)

---

## Out of Scope

- **Issuing** non-SSH secrets (API keys, DB creds, S3 STS, Inter-Hub keys) → OpenBao
  with flex-auth policy where required; ops-warden documents paths only
- Identity / OIDC / MFA → key-cape, Keycloak
- Authorization policy decisions → flex-auth
- Tunnel lifecycle → `ops-bridge`
- Host principal deployment → `railiance-infra`
- OpenBao / Vault cluster deployment → `railiance-platform`
- Human admin SSH key generation (self-service `ssh-keygen`)
- Session recording, SIEM, SSO / Teleport at scale

---

## Relevant When

- Issuing or refreshing an **SSH cert** for `adm`/`agt`/`atm`
- A dev worker needs to know **where to get credentials** in the NetKingdom stack
- `ops-bridge` needs a `cert_command` for a tunnel
- Adding actors to the principals inventory
- Inter-Hub or bootstrap tasks need a **short-lived agent SSH envelope**
- Checking cert-side compliance (scorecard)

---

## Not Relevant When

- Storing or vending **API keys or runtime secrets** (→ OpenBao)
- Policy decisions on resource access (→ flex-auth)
- Managing tunnels without SSH cert issuance (→ ops-bridge)
- Static-key-only legacy access (ops-bridge static key mode)

---

## Current State

- **SSH CLI:** shipped v0.1.0 (WARDEN-WP-0001–0003)
- **Docs:** OpenBao-first config (WARDEN-WP-0005), Inter-Hub bootstrap runbook
- **Registry:** `capability.security.ssh-certificate-issuance` published
- **INTENT:** operational access steward (2026-06-17)
- **Stewardship docs:** WP-0006 complete — routing, inventory patterns, OpenBao checklist
- **Policy gate:** WP-0007 complete — opt-in flex-auth pre-sign
- **Active workplan:** WP-0008 — production SSH path verification and stewardship closeout
- **Gap reassessment:** `history/2026-06-17-post-wp0007-reassessment.md`

## How It Fits (NetKingdom)

```text
key-cape / Keycloak     identity claims
        → flex-auth     authorization decisions
        → OpenBao       runtime secrets & dynamic credentials
        → ops-warden    SSH certs + operational access guidance
        → ops-bridge    tunnel transport (cert_command consumer)
        → railiance-*   deployment and host enforcement
```

Upstream: CA key (local file or OpenBao SSH engine). Actor inventory in Git or
operator config.

Downstream: `ops-bridge` (primary), kaizen agents, CI automations, human operators.

---

## Terminology

- `ActorType`: `adm` | `agt` | `atm`
- `cert_command`: shell command returning a cert on stdout
- `inventory.yaml`: actor → principals + TTL registry
- `LocalCA` / `VaultCA`: signing backends (`backend: local` | `vault`)
