# SECRETS-WP-0004 - Provision a scoped warden-sign token lane
|
|
|
|
## Goal
|
|
|
|
Give ops-warden a scoped OpenBao credential that can run `warden sign` over the
|
|
HTTP API, minted and custodied by secrets-engine. Model it as a first-class
|
|
secrets-engine **auth-capability lane** (an OpenBao policy + AppRole granting a
|
|
narrow capability), not a KV value. Post the non-secret pointers to State Hub and
|
|
hand the token/secret_id to the operator out-of-band.
|
|
|
|
This unblocks FLEX-WP-0007 T4 (the joint OpenBao + policy-gate production smoke),
|
|
after which `policy.enabled: true` can go live on CoulombCore.
|
|
|
|
## Context
|
|
|
|
ops-warden raised this on State Hub (msg 077ac90d, 2026-06-28). warden's vault
|
|
backend signs over the HTTP API (`X-Vault-Token`) and holds no standing OpenBao
|
|
token (conduit-not-broker), so token custody/minting is squarely secrets-engine's
|
|
lane. The operator cannot mint one interactively: the `bao` CLI is not installed
|
|
on CoulombCore and `bao login -method=oidc` is therefore unavailable — hence the
|
|
preference for an AppRole the operator can use non-interactively.
|
|
|
|
Target backend is the **production** OpenBao at `https://bao.coulomb.social`,
|
|
mount `ssh`. Actors in scope: `agt-state-hub-bridge` (primary),
|
|
`agt-codex-interhub-bootstrap`, `adm-example`, `atm-backup-daily`. The signing
|
|
roles are `agt-role`, `adm-role`, `atm-role`.
|
|
|
|
This is the first non-KV, non-npm lane and the first lane that touches production
|
|
OpenBao, so it also exercises parts of the engine the npm pilot did not.
|
|
|
|
## Design Constraints
|
|
|
|
- No token value or AppRole `secret_id` in Git, State Hub, chat, prompts,
|
|
workplans, or normal logs — pointers only on the hub, value out-of-band.
|
|
- The `warden-sign` policy must be narrow: `update` on `ssh/sign/<role>` for the
|
|
allowlisted roles only. No broader `ssh/*`, no `sys/`, `auth/token/`,
|
|
`identity/`, no root/sudo.
|
|
- Production apply uses a mode-0600 bootstrap token outside any repo, revocable,
|
|
recorded in `docs/hardening-backlog.md` H0.
|
|
- ops-warden takes no custody; secrets-engine owns minting and revocation.
|
|
|
|
## Tasks
|
|
|
|
## T01 - Extend the catalog for auth-capability (non-KV) lanes
|
|
|
|
```task
|
|
id: SECRETS-WP-0004-T01
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "278e9a20-eaa6-47a8-9dd7-62952961d520"
|
|
```
|
|
|
|
2026-06-29: Implemented `kind: auth-capability` catalog support, fieldless
|
|
non-KV validation, KV provisioning bypass/rejection, route semantics, and dry-run
|
|
plan/apply handling while preserving the existing KV/npm lane behavior.
|
|
|
|
Add a lane kind that represents an OpenBao auth credential (AppRole + policy)
|
|
granting a capability on a mount, rather than a KV value. The current schema
|
|
assumes a KV `mount/path/fields` value and `provision --from-file`; an
|
|
auth-capability lane has no stored value — the deliverable is the minted token /
|
|
`secret_id`.
|
|
|
|
Acceptance:
|
|
|
|
- The schema validates a `warden-sign` auth-capability lane (kind explicit).
|
|
- KV-only assumptions (`kv_data_path`, from-file provisioning, value verification)
|
|
are bypassed for this kind without weakening the npm KV path.
|
|
- `plan`/`apply` produce a policy + AppRole for the lane.
|
|
|
|
## T02 - Define the warden-sign policy and AppRole
|
|
|
|
```task
|
|
id: SECRETS-WP-0004-T02
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "f4b209e5-c900-4f5e-bb0c-f0c5b27b70c2"
|
|
```
|
|
|
|
2026-06-29: Added `catalog/warden-sign.yaml`, exact `warden-sign` policy/AppRole
|
|
planning, guard coverage rejecting broad `ssh/*`, `sys/`, `auth/token/`,
|
|
`identity/`, wildcard, root-like, and non-`update` grants, plus tests for the
|
|
allowlist and denial probes. Production stage policy now has exact
|
|
`warden-sign` policy/AppRole management exceptions only.
|
|
|
|
Author the `warden-sign` ACL policy and AppRole. Policy: `update` on
|
|
`ssh/sign/agt-role` (plus `adm-role`, `atm-role`) on the `ssh` mount; nothing
|
|
else. AppRole `warden-sign` bound to that policy with a short token TTL, usable
|
|
non-interactively via `role_id` + `secret_id` (no `bao` CLI needed).
|
|
|
|
Acceptance:
|
|
|
|
- The policy lists exact allowed/denied paths; the guards in `roles.py` refuse any
|
|
broader variant (`ssh/*`, `sys/`, `auth/token/`, `identity/`, wildcards, root).
|
|
- Negative check: a token from this AppRole can `sign` only the allowlisted roles
|
|
and is denied elsewhere on the `ssh` mount.
|
|
- The AppRole issues a scoped token carrying only the sign capability.
|
|
|
|
## T03 - Apply against production OpenBao via bootstrap token
|
|
|
|
```task
|
|
id: SECRETS-WP-0004-T03
|
|
status: wait
|
|
priority: high
|
|
state_hub_task_id: "4b414788-d670-496b-9c57-074464a012c4"
|
|
```
|
|
|
|
2026-06-29: Source apply path is implemented and dry-run verified. Live apply is
|
|
waiting on an approved SECRETS-WP-0004 decision/workplan gate plus a mode-0600
|
|
production bootstrap token outside any repo. The pending token path/revocation
|
|
row is recorded in `docs/hardening-backlog.md` H0.
|
|
|
|
Apply the policy + AppRole on `https://bao.coulomb.social` using a mode-0600
|
|
bootstrap token stored outside any repo. Idempotent re-apply.
|
|
|
|
Acceptance:
|
|
|
|
- The `warden-sign` policy and AppRole exist on the production OpenBao.
|
|
- The bootstrap token file is recorded in `docs/hardening-backlog.md` H0 with an
|
|
explicit revocation task and TTL.
|
|
- Apply evidence is non-secret (policy/role names, mount, addr, status — no value).
|
|
|
|
## T04 - Out-of-band handoff and non-secret pointers
|
|
|
|
```task
|
|
id: SECRETS-WP-0004-T04
|
|
status: wait
|
|
priority: high
|
|
state_hub_task_id: "52b5cf88-029f-4f4b-8fe9-0a8dc30378b5"
|
|
```
|
|
|
|
2026-06-29: Added `secrets-engine handoff` and
|
|
`docs/warden-sign-auth-capability.md`. Handoff writes `role_id` and a fresh
|
|
single-use `secret_id` to caller-chosen mode-0600 files outside Git worktrees and
|
|
records only non-secret file paths/TTL metadata. Execution is waiting on live
|
|
apply and attended out-of-band operator delivery.
|
|
|
|
2026-06-29: ops-warden follow-up message `f5b276a3-b90f-454f-b883-83eee7c69616`
|
|
asked for the OIDC login pointer instead of AppRole handoff because Bernd can
|
|
mint the scoped token on his workstation. Added the non-secret pointer:
|
|
`bao login -method=oidc -path=netkingdom role=warden-sign`, role path
|
|
`auth/netkingdom/role/warden-sign`, bound to `groups=["net-kingdom-admins"]`
|
|
and attaching only policy `warden-sign`. Replied to ops-warden in State Hub
|
|
message `0bce1e08-58c2-4db4-b06c-f86cf8142273`; no token value, role_id,
|
|
secret_id, or token accessor was included.
|
|
|
|
Define and execute the handoff: mint a fresh `secret_id`, deliver it (with the
|
|
`role_id`) to the operator out-of-band; warden does `approle login` to obtain a
|
|
`VAULT_TOKEN`. Post the non-secret pointers on the ops-warden thread (policy name,
|
|
AppRole name, mount `ssh`, addr `https://bao.coulomb.social`, token TTL, status).
|
|
|
|
Acceptance:
|
|
|
|
- Pointers are posted to State Hub; no token value or `secret_id` appears there or
|
|
in Git/logs.
|
|
- The operator can run, on CoulombCore:
|
|
`FLEX_AUTH_EXTERNAL=1 SMOKE_VAULT=1 VAULT_TOKEN=<scoped> ~/ops-warden/scripts/policy_gate_production_smoke.sh`.
|
|
|
|
## T05 - Confirm the joint smoke and signal ops-warden
|
|
|
|
```task
|
|
id: SECRETS-WP-0004-T05
|
|
status: wait
|
|
priority: medium
|
|
state_hub_task_id: "aa0f281e-976d-4fcd-b8a3-78582117f86f"
|
|
```
|
|
|
|
2026-06-29: Offline tests pass (`59 passed, 2 skipped`) and route/dry-run CLI
|
|
checks produce non-secret pointers. Joint production smoke and ops-warden signal
|
|
remain waiting on live OpenBao apply, handoff, and operator-run smoke evidence.
|
|
|
|
Confirm the unblock end to end, then reply to ops-warden (msg 077ac90d) with the
|
|
pointers and runbook alignment. The reply is the explicit "we will signal
|
|
ops-warden when done" step.
|
|
|
|
Acceptance:
|
|
|
|
- Allow path resolves to `backend: vault` + a `policy_decision_id`; deny path
|
|
(ttl 999) is rejected by flex-auth before OpenBao.
|
|
- ops-warden is replied to on State Hub with the non-secret pointers.
|
|
- A revocation/rotation task exists for the minted credential.
|
|
|
|
## Exit Criteria
|
|
|
|
- A narrow `warden-sign` policy + AppRole exist on production OpenBao, minted and
|
|
custodied by secrets-engine, granting only `ssh/sign/<allowlisted-role>` update.
|
|
- The operator can obtain a scoped `VAULT_TOKEN` non-interactively without `bao`.
|
|
- FLEX-WP-0007 T4 joint smoke is unblocked (or blocked only on an explicit
|
|
external condition).
|
|
- ops-warden has the non-secret pointers; no secret value crossed State Hub.
|
|
- The bootstrap token and the minted credential have revocation tasks.
