feat: close WP-0009/WP-0013 production integration stewardship strand

Ship flex-auth policy gate registry and smoke evidence, archive WP-0009
through WP-0013, and add integration docs: ops-bridge cert_command
migration playbook, operator OpenBao token hygiene, principals drift
check script, and 2026-06-24 INTENT/SCOPE gap analysis.

# Policy-Gated SSH Signing

## flex-auth policy package (FLEX-WP-0006)
flex-auth owns the `ssh-certificate` / `sign` policy package. ops-warden consumes
it via `POST /v1/check` when `policy.enabled: true`.
**Handoff (canonical):** `~/flex-auth/docs/ops-warden-policy-gate-handoff.md`
| Asset | flex-auth path |
| --- | --- |
| Policy package | `examples/ops-warden/policy_package.md` |
| Allow/deny fixtures | `examples/ops-warden/policy_fixtures.yaml` |
| Registry snapshot | `examples/ops-warden/registry_snapshot.json` |
| Subject manifest | `examples/ops-warden/subject_manifest.yaml` |
| Resource manifest | `examples/ops-warden/resource_manifest.yaml` |
### Tenant and subject bindings
| Field | Value |
| --- | --- |
| Tenant | `tenant:platform` (`policy.tenant`) |
| Resource system | `ops-warden` (`policy.system`) |
| Resource type | `ssh-certificate` |
| Action | `sign` |
| Resource id | `ssh-cert:actor/<actor-name>` |
| Actor type | Example flex-auth subject | ops-warden inventory name pattern |
| --- | --- | --- |
| `adm` | `platform-steward` | `adm-*` |
| `agt` | `ci-deploy-agent` | `agt-*` |
| `atm` | `backup-automation` | `atm-*` |
**Subject id sent to flex-auth:** `WARDEN_POLICY_SUBJECT` when set, otherwise the
inventory actor name. flex-auth may also allow `iam:<actor-name>` when listed in
`allowed_subjects` on the resource.
**Principals and TTL:** Taken from the sign request (inventory defaults). flex-auth
denies when principals are empty/disallowed or TTL exceeds `max_ttl_hours` on the
registered resource.
### Fixture coverage (flex-auth)
Allow: `fixture:ops-warden-adm-sign-allow`, `fixture:ops-warden-agt-sign-allow`,
`fixture:ops-warden-atm-sign-allow`.
Deny: `fixture:ops-warden-unknown-subject-deny`,
`fixture:ops-warden-actor-type-mismatch-deny`, `fixture:ops-warden-ttl-above-max-deny`,
`fixture:ops-warden-disallowed-principal-deny`,
`fixture:ops-warden-missing-fingerprint-deny`.
### Local smoke
```bash
# flex-auth (from ~/flex-auth)
flex-auth serve --addr 127.0.0.1:8080 \
--registry examples/ops-warden/registry_snapshot.json \
--policy examples/ops-warden/policy_package.md \
--log /tmp/flex-auth-ops-warden-decisions.jsonl
# warden.yaml — policy.enabled: true, flex_auth_url pointing at flex-auth
# Use an actor registered in the flex-auth registry (example fixtures use
# template names; production needs a registry slice for real inventory actors).
```
Local end-to-end evidence: `history/2026-06-23-flex-auth-policy-gate-local-smoke.md`.
### Production registry from inventory
Build a flex-auth registry snapshot that mirrors `inventory.yaml` actors:
```bash
python scripts/build_flex_auth_registry.py ~/.config/warden/inventory.yaml \
-o registry/flex-auth/production_registry_snapshot.json
flex-auth load-registry --file registry/flex-auth/production_registry_snapshot.json
```
Re-run after adding or changing actors. Deploy the snapshot to the production
flex-auth runtime together with `~/flex-auth/examples/ops-warden/policy_package.md`.
Smoke (non-secret):
```bash
./scripts/policy_gate_production_smoke.sh
# OpenBao-backed when VAULT_TOKEN is valid:
SMOKE_VAULT=1 ./scripts/policy_gate_production_smoke.sh
```
Evidence: `history/2026-06-23-flex-auth-policy-gate-production-smoke.md`.
---
## Production rollout
1. Deploy flex-auth policies for resource type `ssh-certificate`.
2. Enable `policy.enabled: true` in production `warden.yaml`.
3. Keep `fail_closed: true` unless an explicit break-glass procedure exists.
4. Verify `signatures.log` entries include `policy_decision_id`.
**Keep `policy.enabled: false` until flex-auth is reachable** at `policy.flex_auth_url`
with `fail_closed: true`, unreachable flex-auth blocks all signs.
### Operator checklist
| Step | Owner | Action |
| --- | --- | --- |
| 1 | flex-auth | Deploy runtime; confirm `curl <flex_auth_url>/healthz` → 200 (**FLEX-WP-0007**) |
| 2 | flex-auth | Load production registry + policy package (`~/flex-auth/examples/ops-warden/`) |
| 3 | ops-warden | Regenerate registry from inventory: `scripts/build_flex_auth_registry.py` |
| 4 | ops-warden | Local smoke: `./scripts/policy_gate_production_smoke.sh` |
| 5 | operator | Vault smoke: `SMOKE_VAULT=1 ./scripts/policy_gate_production_smoke.sh` (valid `VAULT_TOKEN`) |
| 6 | operator | Set `policy.flex_auth_url` in `~/.config/warden/warden.yaml` |
| 7 | operator | Set `policy.enabled: true`; keep `fail_closed: true` |
| 8 | operator | Allow smoke: `warden sign <actor>``signatures.log` has `policy_decision_id` |
| 9 | operator | Deny smoke: e.g. `--ttl` above max — CLI shows flex-auth `reason`, no cert |

### Summary
1. Deploy the flex-auth registry and policy package to the production flex-auth
runtime — **not** only the example fixtures.
2. Set `policy.flex_auth_url` to the production flex-auth base URL.
3. Enable `policy.enabled: true` only after steps 15 pass.
4. Keep `fail_closed: true` unless an explicit break-glass procedure exists.
5. Smoke allow and deny paths; preserve non-secret evidence only.
