# FLEX-WP-0017 - Action-bound authorization and durable approval contract

secrets-engine needs production authorization that binds an approval to an
exact action, catalog lane, stage, targets, actor, purpose, validity window,
and distinct approvers. The existing flex-auth decision response and State Hub
decision object each provide only part of that contract.

## Bind execute-time decisions to the evaluated request

```task
id: FLEX-WP-0017-T01
status: done
priority: high
state_hub_task_id: "e7b47e1d-58e8-503c-be89-e8f2050215b1"
```

Add a structured `binding` to standalone `DecisionEnvelope` responses with the
normalized subject, action, resource, context, and full SHA-256 request digest.
Add schema and regression coverage. Prose remains diagnostic only.

## Define the durable authorization object and semantics

```task
id: FLEX-WP-0017-T02
status: done
priority: high
state_hub_task_id: "df7984fb-c31f-5b26-bf42-193e4c3cbb9f"
```

Publish `schemas/action_authorization.schema.json` and
`docs/action-bound-authorization-contract.md`, including exact target mapping,
validity, distinct approvals, supersession, and fail-closed outage semantics.

## Add durable storage and authenticated approval evidence

```task
id: FLEX-WP-0017-T03
status: wait
priority: high
state_hub_task_id: "82d39961-8140-5a7f-9bd8-5164dd1742e5"
```

State Hub must add a structured endpoint/object equivalent to the published
contract, authenticated approval entries, and atomic supersession. Its current
`/decisions/{uuid}` shape has only prose plus a single free-form `decided_by`.
No flex-auth-local substitute is acceptable because flex-auth does not own the
organizational approval lifecycle.

## Propagate bindings through delegated evaluators

```task
id: FLEX-WP-0017-T04
status: done
priority: medium
state_hub_task_id: "d85089ee-ad8c-502b-ba1b-be4ad23aec46"
```

Populate the same binding in Topaz, relationship, rule, and Keycloak adapter
success and fail-closed responses using the shared canonical constructor.

## Consumer handoff and live destructive-action proof

```task
id: FLEX-WP-0017-T05
status: wait
priority: high
state_hub_task_id: "8c3fc0a2-0855-5ac9-afa5-d03b8b1f0bf9"
```

After T03, secrets-engine validates the canonical object before every
privileged production action and proves wrong action/lane/stage/targets,
expiry, supersession, outage, insufficient approvals, and duplicate approvers
all fail before any OpenBao call. Live destroy stays disabled until that proof.
