# WARDEN-WP-0015 — Secret Lifecycle Tiering (policy + conformance)

**Scope:** Establish a NetKingdom standard for how secrets are managed across the
**dev → test → prod** lifecycle, and make ops-warden the **conformance steward** for it.
The standard defines three credential-posture tiers with identical *contracts* and
deliberately divergent *security posture*, plus the phase-change ceremonies between
them. ops-warden authors the ops-security slice of the standard, ships
machine-readable tier descriptors and a conformance checker, and provides a dev-tier
**contract-double** fixture library (the generalization of the "fake bao" pattern).

**Decisions locked (2026-06-27):**
- Authoritative standard lives in **net-kingdom canon** (`docs/`), next to
  `openbao-unseal-custody-models.md` and `responsibility-map.md`. ops-warden authors
  the ops-security slice and carries a pointer + conformance tooling.
- ops-warden role = **author + conformance checks** (machine-readable descriptors,
  drift/conformance checkers, dev-tier doubles). **Not** runtime enforcement.

**Hard boundary (responsibility-map, ~line 154):** ops-warden "must not become a
universal secret broker — runtime secrets remain OpenBao; authorization remains
flex-auth." This WP keeps ops-warden as policy author + conformance verifier only.
OpenBao holds the secrets; flex-auth makes allow/deny decisions.

**Cross-repo note:** T1 authors content destined for **net-kingdom** canon. ops-warden
drafts it; landing it in net-kingdom is a coordinated change through net-kingdom's own
process (inbox/PR), not a unilateral write from this repo.

**Depends on / relates to:** WARDEN-WP-0014 (the `warden access` proxy is the tier-aware
fetch surface; its caller-identity/transit guardrails are tier-prod-compatible).

**Status:** `proposed` — awaiting Bernd's review before implementation.

---

## The model (refined, to be encoded by this WP)

**R1 — Contract parity, posture divergence.** The interface is identical at every
tier; only the backend's security posture changes. Automation written once runs at all
three tiers unchanged. (This is why contract doubles work.)

**R2 — Promote topology, regenerate material.** Secret *values* are never promoted up
the ladder. Only the *structure* (paths, policy shape, names, the secret tree) is
promoted; values are generated fresh at each tier. Test conveniences (reuse,
single-unseal) are quarantined in test by construction.

**R3 — Dev touches no real data, ever.** An insecure personal mock store in dev is
sanctioned *iff* dev uses only synthetic/fixture data. Absolute invariant.

**R4 — Phase-changes are ceremonies, not copies.** test→prod is a gated checklist
(regenerate secrets, switch unseal model, enable break-glass, human sign-off),
referencing the existing net-kingdom `security-bootstrap-*` and unseal-custody docs —
not duplicating them.

**Tier descriptor matrix (encoded in registry/policy):**

| | dev | test | prod |
| --- | --- | --- | --- |
| backend | mock / contract double | OpenBao `-dev` (single-unseal) | OpenBao sealed (Shamir 3-of-5) |
| real values | forbidden (synthetic) | generated, reuse allowed | generated fresh, reuse forbidden |
| unseal | n/a | single key / auto | 3-of-5 + break-glass |
| human-in-loop | never | never | required (break-glass) |
| real user/business data | never | never | allowed |
| audit | optional | on | full, tamper-evident |

## Tasks

### T1 — Author the Secret Lifecycle Tiering standard (canon-bound)

```task
id: WARDEN-WP-0015-T01
status: todo
priority: high
state_hub_task_id: "85aeb676-a593-4056-986a-db14d4c5209f"
```

- [ ] Draft `secret-lifecycle-tiering.md` (R1–R4 + tier matrix + phase-change gates),
      cross-linking `openbao-unseal-custody-models.md`, `responsibility-map.md`,
      `platform-root-custody.md`, and the `security-bootstrap-*` ceremony series.
- [ ] Stage the draft in ops-warden (`history/` or `wiki/`) and open a coordination
      request to **net-kingdom** to land it as authoritative canon (cross-repo).
- [ ] Encode ops-warden's role explicitly: author + conformance, not enforcement/custody.

### T2 — Machine-readable tier descriptors

```task
id: WARDEN-WP-0015-T02
status: todo
priority: high
state_hub_task_id: "011fb0af-154d-40f4-a03e-3172c325321a"
```

- [ ] `registry/policy/secret-lifecycle-tiers.yaml` — the tier matrix as data
      (backend, value-policy, unseal model, human-in-loop, data-class, audit-level).
- [ ] Loader + validation (mirror `routing/catalog.py` rigor; no secret material).
- [ ] Optional `warden policy show|list` lookup (mirrors `warden route`).

### T3 — Conformance checker

```task
id: WARDEN-WP-0015-T03
status: todo
priority: high
state_hub_task_id: "c1a0e987-19d0-478e-ac08-2dbe98e64e09"
```

- [ ] `scripts/check_secret_tier_conformance.py` — given a tier + an environment
      descriptor, assert posture matches the standard (e.g. prod must be sealed +
      Shamir; dev must have no real-value paths). Drift-style report, like
      `check_principals_drift.py`. Read-only; operator runs it.
- [ ] Surface conformance status; never read or print a secret value.

### T4 — Dev-tier contract-double fixture library

```task
id: WARDEN-WP-0015-T04
status: todo
priority: medium
state_hub_task_id: "e556fd2e-4e39-4c7d-bd94-b4330e4bef45"
```

- [ ] Generalize "fake bao": ship hermetic dev-tier doubles for routed subsystems
      (bao, key-cape login) honoring each contract (argv/stdout/exit) with synthetic
      values only — enabling fully offline dev/test of access flows.
- [ ] Document the pattern in the standard (R1) as the sanctioned dev backend.

### T5 — INTENT/SCOPE alignment

```task
id: WARDEN-WP-0015-T05
status: todo
priority: medium
state_hub_task_id: "298c9b09-4a5a-41bf-a3bd-6c572385236b"
```

- [ ] Update `INTENT.md`: ops-warden stewards **security-policy conformance** of the
      infrastructure (authoring the ops-security tiering standard + conformance checks +
      dev doubles), scoped explicitly to author+check — **not** enforcement or custody.
- [ ] SCOPE: add the tiering policy + conformance surface; note the net-kingdom canon
      home; bump the maturity vector where warranted.
- [ ] `history/2026-06-27-secret-lifecycle-tiering-charter.md` — decision record.

## Acceptance

- A coherent dev→test→prod standard exists in net-kingdom canon (R1–R4 + tier matrix +
  phase-change ceremonies), authored by ops-warden, landed via net-kingdom coordination.
- ops-warden ships tier descriptors + a read-only conformance checker + dev-tier doubles.
- No secret material in any descriptor, checker, fixture, doc, or log.
- ops-warden's role is documented as author+conformance; OpenBao custody and flex-auth
  authorization boundaries are explicitly preserved (responsibility-map honored).
- INTENT/SCOPE reflect the conformance-steward role without overclaiming enforcement.
