Owner answer to NK-WP-0056-T02 (hub message 16adf344). Design and proposed lane
|
|
|
|
|
shapes: `docs/bounded-executor-credential-lanes.md`. The engine catalogs and
|
|
|
|
|
statically guards the executor lane. railiance-platform applies the Kubernetes
|
|
|
|
|
auth role and policy through its own CCR, and the executor holds only its own
|
|
|
|
|
15-minute token. Nothing here is a grant or a live change.
|
|
|
|
|
|
|
|
|
|
## Model an existing-auth CAS rotation lane in the catalog
|
|
|
|
|
|
|
|
|
|
```task
|
|
|
|
|
id: SECRETS-WP-0017-T01
|
|
|
|
|
status: wait
|
|
|
|
|
needs_human: true
|
|
|
|
|
blocked_on: founder approval of the Q1 lane shape (docs/bounded-executor-credential-lanes.md)
|
|
|
|
|
priority: high
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Add an explicit lane access mode, for example `access: rotate-cas`, for `kv`
|
|
|
|
|
lanes with `delivery_auth.management: existing`. It renders `["read",
|
|
|
|
|
"update"]` on the exact data path and no `create`, metadata, delete, destroy or
|
|
|
|
|
undelete paths. It requires the `cas_required` declaration, a 15m maximum TTL,
|
|
|
|
|
risk `high`, and rotation and deactivation owners. Kubernetes auth is recorded
|
|
|
|
|
as existing-auth metadata only. Keep the default read-only `lane_policy_paths`
|
|
|
|
|
unchanged. Add tests for the rendered policy and for refusal of wildcard, extra
|
|
|
|
|
capability and metadata variants.
|
|
|
|
|
|
|
|
|
|
## Check a platform policy file against the catalog-rendered policy
|
|
|
|
|
|
|
|
|
|
```task
|
|
|
|
|
id: SECRETS-WP-0017-T02
|
|
|
|
|
status: todo
|
|
|
|
|
priority: medium
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Add a static, offline comparison of a railiance-platform policy HCL with the
|
|
|
|
|
engine-rendered policy for a lane, reported as non-secret pass/fail. Platform
|
|
|
|
|
can run it on the CCR policy file before an attended apply. No OpenBao call.
|
|
|
|
|
|
|
|
|
|
## Add catalog entries for the pilot executor
|
|
|
|
|
|
|
|
|
|
```task
|
|
|
|
|
id: SECRETS-WP-0017-T03
|
|
|
|
|
status: wait
|
|
|
|
|
needs_human: true
|
|
|
|
|
blocked_on: platform CCR for the executor role/policy, and founder choice of LLDAP credential shape
|
|
|
|
|
priority: medium
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Add `nk-bind-executor-svc-authelia` (rotate-cas) and the syn-journey check read
|
|
|
|
|
as non-secret entries that reference the platform CCR and NK-WP-0056. If the
|
|
|
|
|
founder chooses the fallback LLDAP account, also add
|
|
|
|
|
`nk-bind-executor-lldap-credential` (high risk). Use `route` for readiness
|
|
|
|
|
pointers only.
